@Patd - At the cancer center where I am being treated, genetic testing is standard of care. The oncologist will rely on the results of the genetic testing for making decisions on best treatment options going forward after frontline treatment is finished. Depending on the results of the test, there may be maintenance treatment option available that could offer prolonged remission. The testing includes an analysis for about 20 different genetic mutations. Once a patient has provided permission, a sample of tissue taken during the debulking surgery will be sent for analysis. Other than permission, there isn't any action required of the patient, the cancer center looks after the logistics.
If a person was interested in a more extensive analysis, private facilities will test for up to 400 genomic mutations. A report is generated that co-relates the genomic results with currently available effective treatment options and open drug trials. This testing procedure is something done by a patient outside of the cancer center. Foundation One located in Mississauga Ontario offers this service.
