ABSTRACT
At Nara Social Insurance Hospital, from January 2005 to September 2008, chemotherapy for older adult (>or=70) colorectal cancer patients was performed in 18 adjuvant cases and 10 advanced cases. In adjuvant cases, 18 out of 33 patients of >or= stage IIIa received chemotherapy, and 13 completed treatment safely. In advanced cases, all patients received FLOFOX or FOLFIRI, with or without bevacizumab as first-line treatment with a response rate of 50%. Although adverse events were relatively frequent in the older adult patients, there was no difference in the survival rate between elderly and younger patient groups. Cancer chemotherapy for older adults with a high comorbidity rate requires more skill and experience than for younger patients. It was possible even for a small-volume hospital, which plays an important role in regional medical service for elderly patients, to build up a system providing standard chemotherapy for colorectal cancer. However, considering the limited financial and human resources, it is essential to form a regional alliance of designated cancer care hospitals and other clinics in order to maintain the level of practice.
