Colon Cancer Prognosis After Radical Surgery

1. Radical surgery. It is supposed to improve prognosis of colon cancer. A surrogate measure of achievement of radical surgery is the number of lymph nodes removed with the specimen. 2. Markers. There may be variables that may make patient assessment more sound. The project is including investigation of such markers (genes, old age, comorbidity, and others). 3. Laparoscopic resections. This is being used more and more in cancer surgery but the feasibility of this approach remains to be proven compared with conventional open surgery. The project compares these according to 1) and 2). 4. Morbidity and mortality must be surveilled to keep at a minimum. Many patients have comorbidity and are old to make this factor extra important, including perioperative care. 5. Proper treatment of colon metastases may prolong life. Treatment of lung-metastases will be studied in particular.
