Investigational metronomic chemotherapy involves frequent, regularly spaced, long-term administration of a sub-maximum tolerated dose. The phase III CAIRO3 trial evaluated continuous metronomic oral capecitabine, with bevacizumab, as a maintenance treatment in patients with metastatic colorectal cancer; a benefit in progression-free survival compared with observation only was observed, highlighting that metronomic chemotherapy could be a less toxic and convenient therapy.
