With Immunoscore, a test devised by a team of researchers from Inserm and Université Paris Descartes and doctors from the Paris AP-HP hospitals, disease progression in patients with colon cancer can now be defined more accurately. According to an international study conducted in more than 2,500 patients, Immunoscore has proved effective in predicting which patients are at high risk of tumor recurrence and, as such, would benefit from intensified treatment following surgery. These results have been published in The Lancet.
The seriousness of cancer, and particularly that of the colon, is essentially estimated according to the extent to which it has spread within the affected organ and the presence of metastasis. This estimation of the aggressiveness of the cancer and its risk of recurrence following treatment must however be improved.
For decades, it has been thought that the immune reaction developed by the patient against his or her cancer has a beneficial influence. Researchers from Inserm and doctors from the Paris AP-HP hospitals have demonstrated in recent years that infiltration of the cancerous tumor by immune cells is a good indication of the way in which colorectal cancer might develop, thereby representing a potential prognostic tool.
