Objective. To analyze factors influencing survival of patients with stage II colon cancer treated at our cancer center (Sparrow Hospital) from February 1996 through December 2006. Patients and methods. Survival analyses on 197 patients’ age 71.1±0.9 years (29 to 97) were done using SAS system (V9.3, Cary NC). Analysis included age, gender, stage, surgery type, number of examined lymph nodes, pathological grade, tumor size and the use of adjuvant chemotherapy. Results. Mean follow up length was 48.1±2.3 months (0.1-133) and 56±3.3 (0.2-133) for survivors. The average number of removed lymph nodes was 18±13 (1-103). Adjuvant chemotherapy treatment (5-FU± leucovorin) was given to 49 patients, while others (148) were followed expectantly. There were 90 deaths during follow up. Only age exhibits a statistically significant relationship to survival (Hazard Ratio (HR) =1.06, 95% CI=1.03-1.08, p |
