Hi, Thanks for writing in. We all know that viruses are organisms that can self replicate in host cells and alter the DNA in cells. This property has recently been used in the treatment of small cell lung cancer and has been commercially released. Systemically deliverable oncolytic viruses for the treatment of neuroendocrine cancers, such as small cell lung cancer has been produced by a company known as neotropix and you can visit their website to contact them or discuss it with your doctor. This is a step towards research involving harnessing the viruses to stop cell growth and this can be given in addition to surgery, radiation and chemotherapy. Approximately 10% of small cell lung cancer patients receiving treatment will remain free of disease symptoms for up to 2 years from the start of therapy. The aggressive nature of small cell lung cancer, however, usually leads to relapse and the overall survival at 5 years is only 5-10 percent.
