FromJanuary 2002 to December 2006, 41 consecutive patients (27 men and 14 women) aged 75 received radiotherapy for local advanced rectal cancer, 9 in a pre-operative and 22 in a post-operative setting.

Variables considered were age, co-morbidities, evaluated according to the adult co-morbidity evaluation index (ACE-27), surgery versus no surgery, and timing of radiotherapy. The median age was 80.5 years (range 75–90). A total of 19.5% of the patients had no co-morbidity, 48.8% mild, 17.1% moderate, and 14.6% had severe co-morbidities. Thirty-nine subjects (95.1%) were submitted to surgery. All patients but one completed the planned radiation schedule.

The cancer-free survival at 2 and 4 years was 78.9% and 26.4%, respectively. No difference in acute and late toxicity rates was found between patients with different ACE-27 indexes. We conclude that compliance with radiotherapy is good and rate of toxicity is acceptable in elderly patients. Patients with no or mild co-morbidities have a significantly better survival. Increasing severity of co-morbidity may sufficiently shorten remaining life expectancy to cancel gains with adjuvant radiotherapy.

Abstract

A B S T R A C T The purpose of this study was to evaluate the impact of radiotherapy in terms of feasibility and activity in the patients aged 75 with advanced rectal cancer. FromJanuary 2002 to December 2006, 41 consecutive patients (27 men and 14 women) aged 75 received radiotherapy for local advanced rectal cancer, 9 in a pre-operative and 22 in a post-operative setting. Sixteen patients received concomitant chemotherapy. Variables considered were age, co-morbidities, evaluated according to the adult co-morbidity evaluation index (ACE-27), surgery versus no surgery, and timing of radiotherapy. The median age was 80.5 years (range 75–90). A total of 19.5% of the patients had no co-morbidity, 48.8% mild, 17.1% moderate, and 14.6% had severe co-morbidities. Thirty-nine subjects (95.1%) were submitted to surgery. All patients but one completed the planned radiation schedule. At a median follow-up of 23.1 months, the 2- and 4-year overall survival rates were 71.8% and 61.6%, respectively. There was a better survival for patients with no ormild co-morbidities (p = 0.002) and a good performance status (p = 0.003). The cancer-free survival at 2 and 4 years was 78.9% and 26.4%, respectively. No difference in acute and late toxicity rates was found between patients with different ACE-27 indexes.
