OBJECTIVE: To establish reliable standards for surgical application to elderly patients 75 years old or older with gastric or colorectal cancer with special reference to the postoperative recovery of activities of daily living (ADL) and quality of life (QOL). SUMMARY BACKGROUND DATA: ADL and QOL are important outcomes of surgery for the elderly. However, there has been only limited evidence on the natural course of recovery of functional independence. METHODS: Two hundred twenty-three patients 75 years old or older with gastric or colorectal cancer were prospectively examined. Physical conditions, ADL, and QOL were evaluated preoperatively and at the first, third, and sixth postoperative month. RESULTS: The mortality and morbidity rates were 0.4% and 28%, respectively. Twenty-four percent of patients showed a decrease in ADL at 1 month postoperatively, but most patients recovered from this transient reduction, with only 3% showing a decline at the sixth postoperative month (6POM). ADL of these patients was likely to decrease after discharge from the hospital. QOL of the patients showed a recovery to an extent equal to or better than their average preoperative scores. CONCLUSIONS: Of the patients 75 years old or older who underwent elective surgery for gastric or colorectal cancer, only a few showed a protracted decline in ADL and most exhibited better QOL after surgery. This indicates that surgical treatment should be considered, whenever needed, for elderly patients 75 years old or older with gastric or colorectal cancer. Estimation of Physical Ability and Surgical Stress is useful for predicting postoperative declines in ADL and protracted disability; this could aid in establishing a directed rehabilitation program for preventing protracted disability in elderly patients.
