Abstract
In contrast to earlier studies that suggested that colon carcinoma is unusually lethal in the young, 69 patients, ages 20 to 39 years, had a relatively good prognosis. Fifty-nine percent lived over 5 years after diagnosis, and 51% were cured. Furthermore, 67% were cured if they did not have distant spread of the carcinoma at the time of the initial operation. Neither age, sex, tumor size, location, mere presence of lymph node metastases, depth of tumor invasion, nor predisposing disease of the colon was a strong prognostic factor. Metastases to six or more lymph nodes and distant spread of the tumor at the time of initial surgery were ominous findings. Mucinous carcinoma was relatively frequent (28%) and was also an ominous feature (only 5 of 20 patients cured as opposed to 26 of 43 with classical adenocarcinoma).
