[Single-center cohort study of elderly patients with surgically removed colorectal cancers]

Incidence of colorectal cancers (CRCs) increases with age. The surgical and medical management of elderly patients needs to be improved. Until recently, these patients were not included into controlled clinical trials. Between 2004 and 2007, 88 patients (median age 79) had surgery for CRC in our hospital. In half the cases, patients had an emergency surgery (40/88). Twenty patients had dementia, with no relationships between dementia and emergency surgery (50% vs. 45% for patients without dementia), nor between dementia and median length of hospital stay (16 days vs. 22 days). In metastatic setting (20 patients), chemotherapy was omitted in 10 cases, usually patients with dementia (5 patients; p = 0.002) Standard therapy was hardly applicable because many patients were frail. In the future, usefulness of participation to the staffs of a geriatrist will be assessed prospectively.
