Colorectal cancer in patients older than 75 years of age

Two hundred and seven hospital records of patients with colon or rectal cancer from 1982 to 1985 were reviewed retrospectively. Ninetysix patients were 75 years of age or older and 111 were younger than 75 years. Comparison of the two groups showed that the elderly group presented with lower hematocrits and serum albumin values despite comparable pathologic stages and tumor location. A higher preanesthetic stage was seen in the elderly group. The total perioperative mortality rates for the young and elderly groups were 3.6 percent and 7.1 percent, respectively, and were not statistically different. Emergency perioperative mortality rates were 5.2 percent and 10 percent, respectively, and also were not statistically different. All nine patients aged 90 and older underwent a major abdominal operation without the occurrence of any perioperative mortality. This study suggests that age need no longer be considered a major risk factor for immediate surgical outcome in colorectal cancer.
