Tapeworm Drug Inhibits Colon Cancer Metastasis

Plans are already underway with Professor Peter M. Schlag (Charite Comprehensive Cancer Center) to conduct a clinical trial. Colon cancer is one of the most common tumor diseases in Western countries. In Germany alone, there are approximated 73 000 new cases of the disease every year. Despite surgery, chemotherapy and radiation therapy, only about half of the affected patients are cured. The reason is that around 20 percent of the colon cancer patients already have metastases at diagnosis and in about one third of the patients, metastasis occurs despite successful initial treatment. Of these patients with metastatic colon cancer, the five-year survival rate is only about 10 percent. By contrast, for nonmetastatic colon cancer patients the survival rate is 90 percent. Scientists have known for several years that the gene S100A4/metastasin can initiate colon cancer metastasis . Five years ago Professor Stein, working together with Professor Schlag and Professor Walter Birchmeier (MDC), showed how this gene is regulated. They found that the beta-catenin gene, when mutant, activates this S100A4/metastasin gene, thus triggering colon cancer metastasis. Beta-catenin normally regulates cellular adhesion. The scientists looked for compounds that block the expression of the metastasin gene.
