[A retrospective study of UFT and oral leucovorin combination adjuvant chemotherapy for patients over 76 years old with stage III colon cancer].

Objective: To perform a retrospective analysis of UFT and oral leucovorin combination adjuvant chemotherapy for Stage III colon cancer patients over 76 years old, in order to evaluate both treatment efficacy and toxicity.
Subjects: Between 2002 and 2011, 333 Stage III colon cancer patients had surgery performed in our institute, and we studied 25 of them on our chemotherapy regimen.
Results: Patients'median age was 78 years old, with 12 men and 13 women. Of all the patients, 19 had Stage IIIa and 6 had Stage IIIb. The 3-year disease-free survival rates for Stage III and Stage IIIa patients were 65. 1% and 83. 1%, respectively, and the 3-year overall survival rate for Stage III was 79. 9%. With regard to toxicity, liver function disorder was observed in 8% of the patients, being the adverse event that occurred the most, but there was no Grade 3 or 4 toxicity.
Conclusion: UFT and oral leucovorin combination adjuvant chemotherapy for Stage III colon cancer patients over 76 years showed a good response, especially for Stage III a.
