Improving survival in Liver Cancer – at what cost?

No effective therapy is available for advanced hepatocellular carcinoma (liver cancer), it’s a terminal condition. Over 18,000 people typically die from it in the USA each year. It is much more common in Africa and East Asia where the risk of infection from Hepatitis B and C is much higher, which are associated with increased risk factors for the disease.

In this month’s New England Journal of Medicine, a randomised trial involving 602 patients with advanced hepatocellular carcinoma was reported. Sorafenib, a multikinase inhibitor of Raf, vascular endothelial growth factor receptor, and platelet-derived growth factor receptor, improved median survival by 3 months compared to placebo (10.7 vs. 7.9 months, P<0.001). Adverse events, including diarrhea and weight loss, were more frequent in patients receiving sorafenib.

Three months doesn’t sound a lot, but improvements in cancer survival nearly always occur in small increments. The other side of the coin is at what cost?

An editorial by Dr Lewis Roberts in the same journal noted the following:

“The pharmacy price of sorafenib is approximately $5,400 per month in the United States, {euro}3,562 per month in France, $1,400 per month in Korea, and $7,300 per month in China. Even in industrial nations, the high cost of new drugs produces significant stresses on health system budgets. There are substantial ethical implications in having effective therapies available for life threatening diseases that are priced beyond the reach of the populations most in need of therapy.”

Would you pay $15,000 for an extra three months of life?

New treatment option for patients with liver cancer

Treatment with sunitinib (Sutent) slows tumour growth and reduces the risk of metastasis in patients with hepatocellular carcinoma, an aggressive cancer of the liver.

Hepatocellular carcinoma is a cancer that relies heavily on blood vessels for growth; sunitinib controls the growth of blood vessels and could therefore potentially play an important role for treatment.

Patients with this type of liver cancer have a very poor prognosis and the only currently available therapy is sorafenib. This study shows that it may be possible to effectively use sunitinib with manageable side effects, thereby providing patients with an alternative treatment option. Sunitinib (Sutent) is a small molecule tyrosine kinase inhibitor that targets multiple receptors, including VEGFR2, c-Kit and FLT3. These receptors may be present in cancer cells as well as in endothelial and immune cells.

Researchers enrolled 34 patients with advanced liver cancer and gave them 37.5 mg sunitinib daily on a standard four weeks on, two weeks off regimen. By 12 weeks, one patient had a partial response and 17 patients had stable disease. The median progression-free survival was four months and the median overall survival was 10 months.
