- Abstract
Several new aspects have evolved during the past years concerning factors that influence survival in surgically and medically treated colon cancer patients that are relevant to the treating team for the treatment strategy and patient’s choice. The 5-year-survival rates dependent on UICC stages/substages (I: 68%-100%, II: 58%-90%, III: 33%-76%, IV:<5%-9%) show remarkable variations between published reports, surgical hospital units, individual surgeons, and continents (USA vs Europe). Those variations may be due to surgical techniques, training status, hospital and individual case volume, and, also, referral patterns and statistical evaluation methods. Survival times and cure rates are significantly improved by adjuvant chemotherapy in UICC III and in substages of UICC II (e.g. UICC II B) by 5%-12%, when compared with surgical controls. In three recently published trials standard adjuvant chemotherapy was further improved by increased survival rates, e.g. from 59% to 71% in stage III and IIB patients. Molecular and genetic factors, such as thymidylate synthase (TS), microsatellite instability (MSI) or loss of chromosome 18q/“DCC” might have an independent impact on prognosis in the spontaneous course, and TS could help to better select patients for adjuvant chemotherapy.
