ABSTRACT
PURPOSE:
To retrospectively assess the impact of age on tolerance and oncologic outcomes treated by neoadjuvant treatment for patients of 70 years old or above with locally advanced rectal cancer. PATIENTS ANDMETHODS:
Ninety-one consecutive patients were divided into three groups group 1 from 70 to 75 years (n=31); group 2 76 to 79 years (n=31) and group 3, patients aged 80 years or above (n=29). Radiation therapy was delivered according two schemes 25Gy in five fractions (short scheme) or 45 to 50Gy with a classical fractionation (long scheme). Long scheme patients received a concomitant chemotherapy with 5-fluoro-uracile alone or associated with oxaliplatin.RESULTS:
The three groups were comparable for performance status, Charlson's score and T staging. Long scheme radiation therapy and chemotherapy were performed in 77.5, 74.5 and 48.3% of patients (P=0.03) and 77.4, 71 and 41.4% (P=0.006) in the groups 1, 2 and 3, respectively. All patients treated with the short scheme irradiation received the treatment without any acute toxicity. In the long scheme group, 65% of patients received the treatment on time and grade 3 or above toxicity was observed in 12% of patients who did not receive oxaliplatin and in 48% of patients who received oxaliplatin. The overall survival rate at 3 and 5 years was 66.9% and 60.8% in the group 1, 90.5% and 75.9% in the group 2 and 80.5% and 73.8% in the group 3 (P=0.15).CONCLUSION:
Neoadjuvant treatment is feasible with encouraging survival rates for patients aged 70 years and older. Short scheme radiation therapy seems to be an interesting option in this population.
