Adjuvant chemotherapy improves survival amongst octogenarians following resection of colorectal adenocarcinoma.

Octogenarians undergoing treatment for colorectal cancer have similar cancer-specific survival and recurrence-free survival to non-octogenarians. Our study demonstrates a survival benefit when adjuvant therapy is provided to octogenarians, despite only half of this cohort receiving therapy compared to their younger peers. Further research into adjuvant therapy with surgical resection for CRC in older Australians is required.
