Protein Examined for Role in Liver Cancer
17 December 2009
A protein switch called TAK1 helps prevent liver damage, including inflammation, fibrosis and cancer, according to a team of scientists from the United States and Japan. It was already known that TAK1 activates two proteins that play a role in immunity, inflammation, programmed cell death and cancer. However, it wasn't clear whether TAK1 promotes or prevents liver cancer.
To investigate this question, Brenner and colleagues created mice with liver cells that lacked TAK1 and found that the mice had a high rate of liver cell death. To compensate, the rodents' livers produced too many cells, resulting in liver damage that led to liver cancer, the researchers found.

CIC bioGUNE Research Scientists Identify Risk Gene Affecting Liver Regeneration
17 December 2009
Researchers from the CIC bioGUNE, Center for Cooperative Research in BioSciences in Spain, and the Centre for Biomedical Network Research into Hepatic and Digestive Diseases, CIBERehd, have discovered that deficiency of the gene GNMT affects liver regeneration and proliferation. It also produces greater susceptibility when the liver is damages. Researchers found GNMT deficiencies in patients with HCC. Along with other scientists, it has been shown that GNMT is the main gene behind liver metabolism of the SAMe molecule (S-Adenosylmethionine), which is important for ensuring that liver cells multiply correctly. Studies have shown that high levels of SAMe alter the way hepatocytes function, causing uncontrolled proliferation of the liver, which leads to HCC. The total lack of GNMT means uncontrolled SAMe levels, which means the liver is unable to stop hepatic cells from proliferating.

Getting a handle on Posttransplant Recurrence of HCC
17 December 2009
Liver transplantation offers the best overall and recurrence-free survival for the treatment of HCC. Patients with the highest risk of recurrence are those with tumors beyond the Milan criteria, which is a patient with one lesion smaller than 5 cm or up to three lesions smaller than 3 cm. Although there are many reports on the efficacy of adjuvant chemotherapy to prevent recurrence, most have shown no significant gain. It is best to begin chemotherapy as soon as possible after the transplant, but most patients are not medically fit to receive it in the early post-operative period. There are currently two promising unproven agents on the market, sorafenib (Nexavar) and an immunosuppressant sirolimus (Rapamune).

Scientists Uncover Protective Mechanism Against Liver Cancer
14 December 2009
A team of scientist from UC San Diego School of Medicine and Osaka University in Japan identified the protein switch TAK1 that helps prevent liver damage. “TAK1 appears to be a master regulator of liver function,” said David A. Brenner, MD, professor of medicine and Dean of the UC San Diego School of Medicine. TAK1 is a kinase, a type of signaling protein involved in regulating various cell activities, including cell growth. Researchers have known that TAK1 activates two specific proteins, NF-kappaB and JNK, which are both involved in immunity, inflammation, programmed cell death and cancer. But NF-kappaB helps protect liver cells from dying and protects against cancer development. In contrast, JNK promotes cell death and cancer. According to Seki, the study is the first to demonstrate the role of TAK1 in cancer development, and strongly suggests that the protein also contributes to cancer development in other organs.

Green Pigments may Help Prevent Liver Cancer
6 December 2009
According to a study done by researchers at Linus Pauling Institute, eating plenty of green vegetables may help prevent liver cancer. Since green vegetables are high in chlorophyll, the study found that chlorophyll and chlorophyllin may reduce the bioavailability of aflatoxin B, a cancer-causing chemical that can induce liver cancer. For the current study, Dr George Bailey and colleagues examined the effect of co-treatment of chlorophyll and chlorophyllin on bioavailability of aflatoxin B in a few Chinese volunteers. Chlorophyll and chlorophyllin treatment each significantly impeded Aflatoxin B absorption and helped get rid of the toxin quickly in one or more subjects, the researchers found.

Experimental Drug is Combating Hepatitis C in Chimps, Researchers Say
4 December 2009
Researchers reported that an experimental drug, SPC3649 that works by a different mechanism than existing drugs has been shown to suppress hepatitis C in chimpanzees and is already being tested in human clinical trials. SPC3649 is an antisense drug that binds to RNA that is required by the virus for replication. Researchers at Santaris Pharma A/S in Hoersholm, Denmark, and San Diego injected SPC3649 intravenously into four chimpanzees chronically infected with hepatitis C for 12 weeks, followed by 17 weeks of observation. In the two animals receiving the highest dose, there was a 350-fold drop in the virus level. The only side effect of the treatment was a 45% drop in what is called “bad cholesterol.”

Bayer Appeals NICE’s Ruling on Liver Cancer Drug
3 December 2009
Bayer, a Germany-based drug company appealed Britain’s ruling on its critical liver cancer drug which stated, “The price being asked by Bayer is simply too high to justify using NHS money which could be spent on better value cancer treatments.” The drug costs around 2,900 pounds a month and would cost about 8,300 pounds per patient on average. Bayer has offered to give every fourth pack for free. Bayer said that the decision by the National Institute of Health and Clinical Excellence (NICE) to deny critically ill patients’ access to Nexavar was contradictory and accused them of being unfair.

Sorafenib in a Patient with Advanced Hepatocellular Carcinoma and Serious Impairment of Left Ventricular Function: a Case Report
2 December 2009
Sorafenib is a tyrosine-kinase inhibitor and is widely used in the treatment of HCC. Side effects are normally mild and can include an increase of blood pressure. However, side effects may be critical for patients with underlying serious heart disease and may escalate to acute heart failure. A case study was done to either validate or invalidate this theory. The patient had HCC and severe post-ischemic fall of left ventricular function, a type of stroke where the blood supply to the part of the brain is decreases leading to the dysfunction of the brain tissue in that area. He was given a reduced daily dose of 400mg of sorafenib and doctors saw no worsening of his heart function.

Chemoembolization, Survival in Liver Cancer Studied Chemoembolization in Conjunction with Permanent Embolic Agent Provides Longer Survival
25 November 2009
Scientists found that patients with unresectable HCC that had undergone transcatheter arterial chemoembolization (TACE) in conjunction with a permanent embolic agent to cause a blockage, survived longer than patients who underwent TACE only. Antoinette S. Gomes, M.D., of the University of California at Los Angeles, and colleagues assessed the outcomes for 124 patients with unresectable HCC who underwent TACE, including 56 who received triple-drug TACE and a nonpermanent embolic agent, and 68 patients who had triple-drug TACE with a permanent embolic agent. Twenty-eight of the patients went on to have liver transplants and 96 did not. In addition, the researchers found that survival was significantly longer for those who got a liver transplant with a mean survival of 83.45 months.

Association Between the Methylenetetrahydrofolate Reductase C677T Polymorphism and Hepatocellular Carcinoma Risk: A Meta-analysis
24 November 2009
Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the metabolism of folate, folic acids. Scientists have found that the non-synonymous single nucleotide polymorphism (nsSNP) C677T impairs enzyme activity. C677T polymorphism was found to increase the risk of HCC. The study also showed that the TT genotype increased the risk of HCC as compared to the CT genotype. Therefore, MTHFR C677T polymorphism increased the risk of HCC in an over-dominant model and might be a risk factor for HCC occurrence, especially in chronic liver disease patients.

NICE Appraisal of Sorafenib for Advanced Hepatocellular Carcinoma
20 November 2009
The National Institute for Health and Clinical Excellence (NICE) is evaluating the use of sorafenib for the treatment of HCC for patients with unresectable tumors. As of yet, NICE does not recommend sorafenib. Andrew Dillon, Chief Executive of NICE stated, “We were disappointed not to have been able to recommend the use of sorafenib, but after carefully considering all evidence, including the proposed ‘patient access scheme' in which the manufacturer offered to provide every fourth pack free, sorafenib does not provide enough benefit to patients to justify its high cost.”

XPD Codon 312 and 754 Polymorphisms, and AFB1 Exposure, and Hepatocellular Carcinoma Risk
17 November 2009
Genetic polymorphisms in DNA repair genes may influence individual variation in DNA repair capacity, which may be associated with risk of hepatocellular carcinoma (HCC) related to the exposure of aflatoxin B1 (AFB1). Scientists studied 618 cases of HCC and 712 control cases to assess whether or not there was an association between the two polymorphisms, Codon 312 and 754, and the risk of HCC. They concluded that cases with the XPD 751 Gln were at a higher risk of HCC than those with XPD 751 Lys. They also found that the risk was higher for women.

Predicting Prognosis in Hepatocellular Carcinoma after Curative Surgery with Common Clinicopathologic Parameters
3 November 2009
Surgical resection is a curative treatment for HCC, but prognoses thereafter is often difficult to substantiate. Scientists then conducted a retrospective analysis of 572 Chinese HCC patients who had received curative surgery. Findings showed the five common clinicopathologic parameters to be tumor size, number of tumors, tumor stage, venous infiltration status which is the spread of diseased tissue into the veins, and serum-fetoprotein and total albumin levels. There was considerably much variance between the patients. This study could future biomarker inputs and serve as the foundation for future modeling.

Canonical Wnt Signaling is Antagonized by Noncanonical Wnta in Hepatocellular Carcinoma
22 October 2009
Researchers observed that beta-catenin mutations that activate the canonical Wnt signaling do so in a subset of HCC cases. The mutations are associated with chromosomal stability, and low tumor invasion, which leads to better patient survival. Findings lead to the idea that canonical and noncanonica Wnt pathways have complementary roles in HCC. The canonical signaling contributes to tumor initiation and noncanonical signaling to tumor progression.

Combination of Bevacizumab and Erlotinib in Patients with Advanced Hepatocellular Carcinoma
16 September 2009
The combination of bevacizumab and erlotinib in HCC offers a median overall survival of 15.7 months and provides a progression-free survival in HCC patients of 9 months and a response rate of 25%. The combination of the two's toxicity profile is safe and tolerable. Overexpression of various growth factors, including vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), insulin-like growth factor, hepatocyte growth factor, and transforming growth factor, is thought to have a role in the progression of normal liver tissue to cirrhosis. A Phase II clinical trial conducted at The University of Texas M.D. Anderson Cancer Center to evaluate the efficacy of bevacizumab and erlotinib in 40 patients with HCC showed progression-free survival after 16 weeks.

NICE Rejects Liver Cancer Treatment
9 September 2009
A liver cancer drug has been rejected for use by the UK's cost-effectiveness healthcare watchdog even though the drug company has lowered the cost of the treatment. Nexavar, also known as sorafenib, created by Bayer was designed to help treat HCC. The National Institute of Health and Clinical Excellence (NICE) had previously refused to accept the drug for treating kidney cancers, and it is being refused now a second time for the treatment of liver cancer. Bayer has proven that Nexavar works for liver and kidney cancer.

Race Not Shown to Affect Liver Transplant Outcome Recurrence of Hepatocellular Carcinoma is Only Predictor of Survival After Transplant
3 September 2009
Researchers found that liver transplant outcomes for patients with hepatitis B are similar regardless of whether the patient is Caucasian, Asia, or African American. Natalie Bzowej, M.D. of California Pacific Medical Center in San Francisco analyzed data from 15 American transplant centers on 274 patients. 116 were Caucasian, 135 were Asian, and 23 were African-American. Of the 170 patients to undergo liver transplant, 19 died. Bzowej and researchers found all three groups had similar odds. The recurrence rated for HCC, the only predictor of survival, were also similar among all groups.

DGAP-News: 4SC Commences Phase II Trial in Hepatocellular Carcinoma (HCC) with the HDAC Inhibitor 4SC-201
18 August 2009
4SC AG, a drug discovery and development company focused on autoimmune and cancer indications, has begun its phase II trial of 4SC-201. 4SC-201 (resminostat) is a pan-histone deacetylase (HDAC) inhibitor and is a new potential treatment option for patients with advanced hepatocellular carcinoma (HCC). HDAC inhibitors modify the DNA structure of tumour cells to cause their differentiation and programmed cell death, and are able to potentially stop tumor progression and therapeutically control the cancer. The study will evaluate efficacy, safety, and pharmacokinetics. Researchers will also be treating in combination with sorafenib and examining whether treatment of 4sc-201 alone or with sorafenib can increase progression free survival and tumor response.

Egyptian Congress Focuses on Hepatitis Treatment
17 August 2009
The Egyptian Society of Hepatology, Gastroenterology and Infectious Diseases (ESHGID) emphasized on hepatitis C (HCV) treatment as the key to tackling Egypt's growing liver cancer problem. “The issue we face exceeds all expectations. We need to move beyond blaming hepatitis C prevalence on anti-Bilharzia injections; this method of transmission has ceased since 1983. Current prevalence of HCV is directly related to lifestyle factors. Lack of awareness of proper hygiene and sterilization measures is the main means of transmission,” said Dr Helmy Abaza, professor of Gastroenterology at Alexandria University and president of the society.

Exogenous Cx43 Expression Decrease Cell Proliferation Rate in Rat Hepatocarcinoma Cell Independently of Function Gap Junction
13 August 2009
Gap junction intercellular communication (GJIC) plays a role in the regulation of homeostasis because it regulates important processes including cell proliferation and cell differentiation. A reduced or lost GJIC capacity has been seen in solid tumors and studies show that GJIC restoration in tumor cells help the reversion of the transformed phenotype. The study was based on recent reports that an increase in the expression of specific connexins such as Cx43, which is a major structural protein, can contribute to reversion of the malignant portion of tumor cells. The results showed that Cx43 did not increase GJIC capacity of transfected cells, but was critical to decrease the cell proliferation rates. In conclusion, Cx43 expression lead to decreased growth of the rat hepatocellular carcinoma cells and contributed to the reversion of the transformed phenotype.

Sequential TACE and Cryosurgery can Improve Survival Times for Patients with HCC
12 August 2009
Cryosurgery is a minimally invasive technique of using extreme low temperatures to freeze and kill tumors. Cryosurgery can be used on virtually any solid organ cancer where conventional surgery would be unable to remove the tissue. Transarterial chemoembolization (TACE) is a procedure in which the blood supply to a tumor is blocked and chemotherapy is administered directly into the tumor. TACE performed prior to cryoablation may increase the efficacy of the cryoablation for HCC, to decrease local recurrence at the ablation area, improve survival times, and reduce bleeding complications.

Multiple Pregnancies may Reduce the Risk of Liver Cancer Among Women with Hepatitis B Virus
11 August 2009
According to one study led by researchers at the Johns Hopkins Bloomberg School of Public Health, women with Hepatitis B virus (HBV) who have had multiple pregnancies are at a reduced risk of developing hepatocellular carcinoma (HCC). Researchers evaluated the incidence and risk factors for hepatocellular carcinoma among pregnant women in Taiwan who were screened for HBV infection to prevent transmission of the virus to their infants. They found that markers of active HBC viral replication were associated with a greater risk of later developing hepatocellular carcinoma than those who had inactive chronic HBV infection. This leads to the hypothesis of whether estrogen and progesterone secretion during pregnancy may have provided some protection from HBV-induced liver cancer.

MDRNA Begins Primate Studies in Liver Cancer Program, Adds Bladder Cancer to Pipeline
6 August 2009
MDRNA began studies to find a new lead drug candidate by the end of the year. CSO Barry Polisky noted that the company has been able to demonstrate “efficient delivery and effective knockdown of multiple targets in rodents,” including an in-house rodent model of the liver cancer. Researchers found that UsiRNAs in which the bond between two adjacent carbon atoms of riboseis removed, trigger significant inhibition of apolipoprotien B. Months later, the scientists also found that the same drug could inhibit expression of a blood-clotting factor. Taking the testing to the next level with primates, explains Polisky, will study the tolerability of the RNAi drugs and provide functional, targeted data.

The Extremes of BMI a Cause for Concern in Liver Transplantation
4 August 2009
A recent study by doctors at the University of Washington explained that patients who are significantly underweight or very severely obese prior to liver transplantation are at increased risk of death following transplantation surgery. The research team was led by André A. S. Dick, M.D., Department of Surgery, Division of Transplantation, University of Washington. He investigated the impact of pre-transplantation Body Mass Index (BMI) on post-liver transplantation patient survival. The underweight patients had a higher re-transplantation rate because of the inability to graft, and they were more likely to die from hemorrhagic complications. Patients that were obese had higher rates of death due to infections complications.

Researchers Identify Genes Linked to Chemoresistance
20 July 2009
Researchers are examining ways to prevent resistance by determining the molecular mechanisms involved with cancer progression, and then developing new generations of chemotherapeutic agents. Researchers found two genes, astrocyte elecated gene-1 (AEG-1) and late SV40 factor (LSF), to contribute to resistance of a commonly used chemotherapeutic drug called 5-fluorouracil (5-FU). The team found that over-expression of AEG-1 increase resistance of the liver cells to 5-FU. The researchers also identified that LSF, a transcription factor that regulates gene expression, is increased by AEG-1.

Twist Expression Promotes Migration and Invasion in Hepatocellular Carcinoma
18 July 2009
Twist, a synthesis of RNA factor, is reported to regulate cancer metastasis. It is known to induce epithelial-mesenchymal transition (EMT), a program of development of biological cells characterized by loss of cell adhesion and increased cell mobility. The study evaluated the expression of twist and its effect on cell migration in HCC. The team examined 20 tissue samples of HCC and assessed twist expression. They found strong and intermediate twist expression in 7 of 20 tumor samples and no significant twist expression was found in the tumor-free resection margins. In conclusions, twist induces migratory effect on hepatocellular carcinoma by causing epithelial-mesenchymal transition.

MicroRNAs Show Promise for Detecting, Treating Cancer
30 June 2009
Scientist have discovered microRNAs which are no more than 20 nucleotides in length and do not uphold the long-thought belief that nucleotides are only passive carriers of genetic information. It turns out that microRNAs are non-coding RNAs that do not pass on the instructions for assembling proteins, but instead, act like proteins serving as potent regulators of gene expression. In a recent study, microRNA was able to distinguish the correct tissue for cancers of unknown primary origin with more than 90 percent accuracy. The role of microRNAs in carcinogenesis also makes them a promising target for treatment. Especially attractive is the fact that one microRNA can regulate many, even hundreds, of gene targets.

The 6 Cancer-Fighting Foods You're Not Eating Enough Of
22 June 2009
The phrase “you are what you eat” may be true. Eating unhealthy foods may cause your body to become susceptible to many diseases. Several foods can help prevent cancer and fight abnormal cell growth in people diagnosed with cancer. Avocados are rich in antioxidants that attack free radicals in the body, which are thought to be a major contributor to cancer. Avocados are also known for helping fight liver cancer. Flax also contains antioxidants, and when the seeds are crushed the oils produced can help fight cancer as well. Garlic is great for the immune system and can slow the development and growth of tumors. Grapefruits, oranges and grapes contain citrus which flushes the body of carcinogens.

Cancer Spread to Liver Responds to Experimental Treatment
22 June 2009
Percutaneous hepatic perfusion (PHP) is a procedure that targets tumors with a dose of chemotherapy that is ten times stronger than patients would otherwise receive. A special catheter applies the drug only to the liver, thus reducing the risk of damaging nearby organs and minimizing side effects. “This technique involves only a couple of small holes [in the skin] to place the catheters, so patients generally recover quickly and are released from the hospital in a day or two,” said Dr. Fred Moeslein, an interventional radiologist at the University Of Maryland School Of Medicine who performs the procedure.

An Effective Target of Biological Therapy for Hepatocellular Carcinoma
15 June 2009
Several studies have shown activated STAT3 to be detected in many HCC cell lines, which suggests that it can be a promising molecular target for HCC gene therapy. RNA interference (RNAi) is a controlling, gene-silencing mechanism where the RNA sequences can be introduced into cells that show the expression of a particular gene. A research team led by Professor Piao from Liaoning Medical University and Jinlin University used RNAi to block sequences displaying STAT3 to evaluate its effects on tumor growth. Tests showed that by silencing STAT3 using RNAi increased cell death within the tumor and prevented proliferation and maturation of malignant cells.

An Alternative Treatment for Hypervascular Hepatocellular Carcinoma
15 June 2009
Radio frequency Ablation (RFA) has been used more and more as a safe technique for treating tumors in the liver. However, RFA seems less effective on hypervascular hepatocellular carcinoma (HCC). Another treatment, transcatheter arterial chemoembolization (TACE), can reduce the blood supply of HCC by closing the arteries to the tumor. For the treatment of hypervascular HCC percutaneous arterial ablation (PAA) can be used to reduce, or even block, the blood flow to the tumors. A research team led by Professor Chen from Peking University School of Oncology, Beijing Cancer Hospital and Institute, studied 154 HCC patients with 177 hypervascular lesions, to evaluate the feasibility and adjuvant value (or how much the process could be sped up) of PAA performed before routine RFA treatment of hypervascular HCC. The combination of PAA and RFA may significantly decrease post-RFA recurrence and provide a safe and effective treatment for hypervascular HCC.

Is DKK-3 and WIF-1: Proteins Related to Liver Cancer Development?
15 June 2009
The Wnt-antagonist genes function as tumor-suppressors and contribute to the development of tissue of many human cancers. A study suggests that proteins written by DKK-3 and WIF-1 can act as cancer-associated proteins that relate with liver cancer development. Silencing the DKK-3 gene and the WIF-1 gene resulted from hypermethylation, or an activity of genes that can cause oncogenes to produce proteins that cause malignant behavior. The expression of DKK-3 is negatively related to the stage of tumor and cell growth. DKK-3 and WIF-1 may provide a reliable way to improve liver cancer early diagnosis and therapies.

The Bug That Can Blast Away Cancer: Drug Made From Virus Extends Patients' Lives
9 June 2009
Reolysin, a living virus, has been shown to kill off cancer cells by rupturing their walls that creates a chain reaction and rips through the tumor. By shrinking the tumor, it becomes less harmful, and easier to remove. Reolysin appears to simultaneously “wake up” the immune system to recognize cancer cells as invaders and attack them. Lead researcher Professor Alan Melcher said, “It is a completely different approach to treating cancer. It is not just another drug. It is a virus and it seems to be very well tolerated in combination with chemotherapy.”

New Screening Test Could Reduce High Mortality Rates in Patients with Liver Cancer
3 June 2009
Dr. Jorge Filmus, a Senior Scientist at Sunnybrook Health Sciences Center in Toronto has been developing a new test to proactively screen patients for liver cancer. His test would be able to find tumors while they are still small enough to remove, which would reduce the disease's high mortality rate. The test uses antibodies to detect the presence of glypican-3, a biomarker in the patient's blood. Most doctors use the alpha-fetoprotein blood test or an ultrasound. Dr. Filmus estimates the cost of his test would be $25 per patient. His lab is working with BioMosaics and Amorfix Life Sciences to increase the sensitivity of his test.

Hope for Cancer
3 May 2009
There are many treatments for liver disease including hepatocellular carcinoma (HCC), and patients should fully understand all the options available:
- Chemoembolization involves the injection of one or more cancer drugs directly into the blood vessels that nourish the tumor, which targets the tumors without poisoning the rest of the body.
- Radio-Active Particle Implant (RAPI), in the form or brachytherapy, is a type of radiation therapy in which radioactive materials are placed in direct contact with the tissue being treated.
- High-Intensity Focused Ultrasound (HIFU) is used to kill tumor cancer cells by using heat generated by an ultrasound.
- With lymphocyte/NK cell transfusions, compatible blood from the closest relatives is collected and the lymphocytes, the white blood cells that fight infection and disease, are isolated. The NK cells, or natural killer cells, which are the body's main cancer-fighting cells, are isolated, and the NK-rich fraction is transfused into the patient.
- Nano transfusion makes it possible to deliver tiny, radioactive atoms and chemotherapy molecules to cancer cells throughout the body with minimal harm to normal cells.

Drug-Eluting Beads Significantly Reduce Doxorubicin Toxicity in Patients with HCC: Presented at EASL
29 April 2009
Researchers presented their findings on drug-eluting glass “beads” (DEB-TACE) that are filled with doxorubicin at the 44th Annual Meeting of the European Association for the Study of Liver (RASL). The “beads” may be better than treating with transarterial chemoembolization (c-TACE) for hepatocellular carcinoma (HCC). DEB-TACE produced a significantly higher objective response and disease control among patients who had a more advanced stage of HCC. The study involved 200 patients that received either DEB-TACE or c-TACE. DEB-TACE may be superior because the beads better moderate the doxorubicin uptake and provide a more gradual and long-lasting treatment.

Attacking Liver Cancer with Highly Concentrated Chemo Dose
31 March 2009
Researchers at the Nation Institutes for Health are looking into a new approach known as percutaneous hepatic perfusion, or PHP, which is an extremely aggressive form of chemotherapy that targets cancer that has spread to the liver. With PHP doctors use balloons, like those used in heart surgery, to seal off a patient's liver to directly apply the super-high dose of chemo without it spreading throughout the body. Dr. Elliot Levy, of the NIH uses x-ray images to inflate the balloons which block the blood from exiting as usual. Dye is injected to verify the seal is properly maintained. Then the chemo is administered through a drip for 30 minutes.

Treatment Approach Using Radiofrequency Waves Heats Up
24 March 2009
A retired radio engineer and executive John Kanzius came to the realization that radio frequency (RF) is an ideal way to attack cancer cells from outside the body. At low levels, RF can heat up metal to 130° F in minutes, while not doing any harm to healthy tissue. Kanzuis used RF waves to heat up metal nanoparticles that found their way into cancer cells. Dr. David Geller from the University of Pittsburgh Medical Center and Dr. Steven A Curley from the University of Texas M.D. Anderson Cancer Center used RF to heat up liver tumors in rats using gold nanoparticles that were injected directly onto the tumors. Both are still working to find molecules that are highly specific to cancer cells.
Currently Texas-based Nanospectra Biosciences received approval from the FDA for their Phase I study using a devise that emits near-infrared light to heat up gold nanoparticles in tumors. Also, MagForce in Germany developed a device that uses and alternating magnetic field to heat up magnetized nanoparticles. They are also testing it in Phase I and II trials in Europe.

Proteomics Prove Accurate In Identifying Liver Cancer
5 March 2009
A study led by researchers at Beth Israel Deaconess Medical Center (BIDMC), in Massachusetts, demonstrated a mass-spectrometry based form of proteomic profiling, which is the study of proteins by observing their wavelengths of light. They found that this is more accurate than traditional biomarkers in distinguishing liver cancer patients from patients with hepatitis C. Examining 92 patients, researchers were able to identify an 11-protein signature that accurately differentiates between cirrhosis and cancer.
The best hope for early detection is cancer biomarkers, which are the serum proteins found in blood and other body fluids. The current biomarker for liver cancer is the alpha-fetoprotein (AFP), a substance normally produced by liver cells. Patients with hepatitis C are routinely monitored for AFP levels.

A Vaccine Offers Instant Immunity
3 March 2009
By exposing the body's immune system to inactive forms of a virus or bacteria, a vaccine trains antibodies to fight off the invasion. While vaccines prepare antibodies, they do not give specific instructions on how exactly to do it. This is part of the reason why it can take several weeks or months for vaccines to build up an effective immune response. Researchers at Scripps Research Institute in Florida have begun to develop pre-programmed chemicals that bind antibodies and tell them how to recognize part of a pathogen. Through their experiments, the researchers found that these chemicals promoted a therapeutic immune response that inhibited the growth of two types of tumors in mice.
Additionally, in the past few years, researchers have identified cell-surface markers that are unique to cancer cells, called adjuvants. Adjuvants trick the immune system into recognizing and attacking tumors. Researchers continue to find ways to genetically engineer antibodies that will be able to recognize tumor markers and attack cancer.

Researchers Identify Gene Linked to Aggressive Progression of Liver Cancer
17 February 2009
Researchers at Virginia Commonwealth University have identifies a gene, AEG-1, that plays a key role in regulating liver cancer progression. After examining human liver cancer rumor cells from patients with hepatocellular carcinoma (HCC), they found that the expression of AEG-1 increases as the tumor becomes more aggressive. Researchers also determined that AEG-1 expression of genes is relevant to the progression of HCC, including invasion, metastasis and resistance to chemotherapy.
“AEG-1 also activates multiple intracellular signaling pathways that are known to be involved in HCC progression. So, strategies to inhibit AEG-1 that could lead to the shutdown of these pathways, either by small molecules or by siRNAs, might be an important therapeutic modality for HCC patients,” said principal investigator Devan Sarkar, Ph.D., MBBS, assistant professor in the Department of Human and Molecular Genetics in the VCU School of Medicine.

Treat Viral Hepatitis, Liver Cancer with New Molecule
12 February 2009
Researchers at the department of Gene Therapy and Hepatology at the Centre for Applied Medical Research at the University of Navarra in Spain have identified a molecule, which can be potentially effective in treating chronic hepatitis and liver cancer. They found that dendritic cells, which are natural proteins produced by the immune system that respond to foreign agents, also produce Oncostatin M, along with type 1 interferon, during viral infection. This shows that the combination of Oncostatin M and type 1 interferon can be used to treat viral diseases. Digna Biotech, a Spanish biotechnology company, will further develop this new combination for clinical application.

Radiofrequency Treatment Better than Ethanol Injection for Small Liver Tumors, Study Suggests
9 February 2009
The American Association for the Study Of Liver Diseases (AASLD) recommends percutaneous ethanol injection (PEI) as a safe and effective treatment for small hepatocellular carcinomas. Recently, four trials that directly compare PEI to radiofrequency ablation (RFA) stated that RFA significantly improved patients’ survival.
Dr. Yun Ku Cho and his team of researchers in Seoul, South Korea, conducted several searches for studies on the comparison of RFA and PEI between 1978 and 2008 and found that many trials “identified definite survival benefit favoring RFA compared to PEI.” Their research also showed a significant improvement in the three-year survival for patients who had undergone RFA.

Avastin® Plus Traceva® Shows Promise in Advanced Hepatocellular Carcinoma
3 February 2009
Based on results from a Phase II clinical trial, Avastin and Tarceva, together, showed anticancer activity in patients with advanced hepatocellular carcinoma. Acastin is an anticancer drug that targets the growth of new blood vessels by inhibiting a protein that deprives the cancer of oxygen and nutrients. Traceva works by blocking the pathway involved in cell growth and replication when it is mutated.
The Phase II clinical study consisted of 40 patients that had non-resectable tumors. 63% of the patients remained free of cancer progression for 16 weeks.

Surgeons Use Microwave Technology to Destroy Tumors
3 February 2009
Microwave ablation is a new minimally invasive treatment for liver tumors. This technology uses the heat produced from radiofrequency waves to destroy abnormal tissues. The procedure is done with a small antenna that pierces through the skin into the tumor. The antenna then emits microwaves, producing friction, which in turn, produces heat, causing cellular death at 140°F.
Dr. Marquis Hart, a transplant surgeon at UC San Diego Medical Center, states, “Microwave ablation causes the tumor to be quickly and precisely removed. If necessary, multiple tumors can be treated at the same time … This method appears to be more efficient than other ablation techniques, which translates to better tumor destruction and less time for the patient under general anesthesia.”

Protein Predicts Liver Cancer Recurrence and Metastasis after Transplantation
1 February 2009
A new study shows that a protein, Capn4, involved with cell migration, can be associated with liver cancer recurrence and metastasis after liver transplantation. Capn4 can be used as a biomarker for diagnosis and a target for therapy. Researchers at the Liver Cancer Institute in Shanghai studied liver cancer cells in search of proteins associated with recurrence of hepatocellular carcinoma after liver transplantation. They were able to identify 149 protients, but primarily focused on Capn4, which had a significant correlation with tumor number, maximum tumor size and tumor encapsulation.

Early and Very Early Hepatocellular Carcinoma: When and How Much do Staging and Choice of Treatment Really Matter? A Multi-Center Study
27 January 2009
Researchers looked at 530 HCC patients, and investigated how many patients were diagnosed in “very early” and “early” stage based on treatment and whether their survival depends on treatment. Because most patients with “very early” HCC were not treated with the treatment suggested as the most appropriate by the American Association for the Study of Liver Diseases (AASLD) guidelinees thus the type of treatment had no impact on survival. The “early” stage group was also rarely treated according to the AASLD guidelines, but their survival was partially predicted by the type of treatment.

Solitary Necrotic Nodule of the Liver Mimicking Hepatocellular Carcinoma: A Case Study
25 January 2009
Solitary necrotic nodule is a rare lesion on the liver, which looks similar on x-ray pictures as those of tumors, or other masses on the liver. In such instances, liver resection is necessary to determine what the actual entity is and rule out hepatocellular carcinoma. Symptoms of solitary necrotic nodule include abdominal pain and high fever.

TRIP-Br2 Promotes Oncogenesis in Nude Mice and is Frequently Overexpressed in Multiple Human Tumors
20 January 2009
Clinicopathologic (the signs and symptoms manifested by a patient) and laboratory results were studied to assess whether or not TRIP-Br2 could be a possible prognostic marker of human cancer, and a chemotherapeutic drug target. Researchers found overexpression of TRIP-Br2, which was ample to change the fibroblasts (connective tissue cells) of mice and promote new growths. Clinicopathologic correlation also indicates that overexpression of TRIP-Br2 in hepatocellular carcinoma is the worst clinical outcome according to the Kaplan-Meier survival analysis, which is used to measure the fraction of patients' livers for a certain amount of time after the treatment. In conclusion, the study identified TRIP-Br2 as a legitimate proto-oncogene, or a mutated and overexpressed version of the normal gene.

Tiny Chemo Beads Boost Liver Cancer Outcomes
20 January 2009
The European Institute of Oncology in Italy has been working with a new technique for the treatment of liver cancer. Transarterial chemoembolization (TACE) is a process that attacks liver tumors with microspheres of chemotherapeutic agents that are delivered directly into the tumor, which cuts off its blood supply. Dr. Franco Orsi, the chief of interventional radiology at the European Institute of Oncology stated, “One of the main benefits of Embozene microspheres is the precise, well-calibrated sizing, which match the small blood vessels that feed the tumors … Moreover, chemoembolization without drugs usually causes few or no post-treatment side effects, and patient can usually be discharged the next day.”
In a study done at St. Joseph's Hospital and Medical Center in Florida, ten out of eleven patients that received TACE, were still alive two years later. In an Italian study, about 46 out of the 53 patients showed a complete response to the therapy after six months.

A Novel Regulatory Event-Based Gene Set Analysis Method for Exploring Global Functional Changes in Heterogeneous Genomic Data Sets
16 January 2009
The new approach for microarray data analysis, a technique for performing many DNA experiments in parallel, consists of analyzing gene expression data by assessing the significance of pre-defined gene sets, rather than individual genes. The regulatory event-based Gene Set Analysis (eGSA) considers every gene event and consistently changed genes of each sample to overcome the detection limit. eGSA, when compared to conventional methods, can better detect functional changes in heterogeneous samples. Through eGSA, researchers have also found a new functional characteristic and potential mechanism of very early hepatocellular carcinoma (HCC).

Jennerex Treats First Patients in Phase 2 JX-594 Trial for Liver Cancer
12 January 2009
Jennerex Inc. and Green Cross Corp. have treated their first five patients with their new treatment, poxvirus JX-594, which is a bio-therapeutic product and a breakthrough in armed oncolytic poxvirus. Oncolytic, meaning the destruction of tumor cells, and the poxvirus is a virus that multiplies in the cytoplasm of the cell and establishes a second nucleus. Jx-594 selectively multiplies within the cancer cells and leads to their destruction. Then, newly created copies of JX-594 are released and are able to infect other tumor cells.
So far, no significant toxicities were reported. In phase 2, the two companies are testing the efficacy, safety and tolerability of JX-594 at two different doses. The treatment aims to stop tumor progression in patients with unresectable primary hepatocellular carcinoma (HCC).

Implementation of Newborn Hepatitis B Vaccination — Worldwide, 2006
7 January 2009
The World Health Organization (WHO) is the authority for health within the United Nations system. They are responsible for providing leadership on global health matters, shaping the health research agenda, setting standards, providing technical to countries, and monitoring and assessing health trends. In 1992, WHO set the goal that all countries introduce the hepatitis B vaccine into the national routine infant immunization programs by 1997. The vaccine would be given to infants within the first 24 hours of birth to prevent perinatal (the period of time shortly before and after birth) HBV transmission. As of 2006, 81 of the 193 WHO member states indicated that the hepatitis B vaccine had been included in the national infant immunization schedule.

From a Machine That Reads your Thoughts to Glasses That Cure Dry Eyes: The Breakthroughs That Will Change Lives in 2009
6 January 2009
Patients with inoperable liver cancer and primary cancer tumors can now be treated with an intra-arterial chemotherapy. This is where microscopic beads loaded either with a high concentrate of a chemotherapy or a radiotherapy drug are pumped in via a catheter to the main blood supply to the liver. This treatment is now available at The Christie in Manchester and the Hammersmith Hospital in London.
The drug then disperses into the smaller blood vessels of the liver and is able to reach the most inaccessible of tumors. Professor Gaines, an interventional radiologist at the Sheffield Vascular Institute in the UK, stated, “Trials have shown it can extend life span by an extra year for those with previously untreatable secondary liver cancer.”
