text_1: Metastatic colorectal cancer treated with a single agent fluoropyrimidines resulted in similar efficacy and better quality of life when compared with oxaliplatin-based chemotherapy in elderly patients.
text_2: In multivariable analysis, fewer baseline symptoms (odds ratio 1·32, 95% CI 1·14-1·52), less widespread disease (1·51, 1·05-2·19), and use of oxaliplatin (0·57, 0·39-0·82) were predictive of better OTU.
