Immunotherapy prior to surgery is effective in colon cancer
(PHYSorg.com Medicine & Health)

Patients with colon cancer but without distant metastases can benefit from a short course of immunotherapy while waiting for their surgery, as it can cause tumours to shrink substantially or clear up in a very short time. The patient`s own immune cells clear away the cancer cells. This is the finding of a NICHE study by the Netherlands Cancer Institute, an innovatory phase II clinical trial. In patients with a specific subtype of colon cancer (MSI), 100% of the patients benefited from the therapy. Twenty-five percent of those with MSS type benefited.
