Medical treatment of cancer is based on guidelines from the European and American Society of Medical Oncology. Regarding palliative treatment so called 1. Line Therapy is started and in case of resistance or intolerable side effects, treatment is changed to 2. Line Therapy containing different drugs. Beyond 2. Line Therapy there is rarely more help to get from guidelines and treatment becomes experimental or based or doctor´s choice. Today, it is typical at this point you can consider whether IndiTreat® testing is for you to try. However, you may consider discussing IndiTreat® guided treatment with your doctor already after failure of 1. Line Treatment.
