A randomised study evaluating the use of pyridoxine to avoid capecitabine dose modifications
BACKGROUND: Pyridoxine is frequently used to treat capecitabine-induced hand–foot syndrome (HFS), although the evidence of benefit is lacking. We performed a randomised placebo-controlled trial to determine whether pyridoxine could avoid the need for capecitabine dose modifications and improve outco...

Sumario: | BACKGROUND: Pyridoxine is frequently used to treat capecitabine-induced hand–foot syndrome (HFS), although the evidence of benefit is lacking. We performed a randomised placebo-controlled trial to determine whether pyridoxine could avoid the need for capecitabine dose modifications and improve outcomes. METHODS: A total of 106 patients planned for palliative single-agent capecitabine (53 in each arm, 65%/ 35% colorectal/breast cancer) were randomised to receive either concomitant pyridoxine (50 mg po) or matching placebo three times daily. RESULTS: Compared with placebo, pyridoxine use was associated with an increased rate of avoiding capecitabine dose modifications (37% vs 23%, relative risk 0.59, 95% CI 0.29, 1.20, P=0.15) and fewer grade 3/4 HFS-related adverse events (9% vs 17%, odds ratio 0.51, 95% CI 0.15–1.6, P=0.26). Use of pyridoxine did not improve response rate or progression-free survival. CONCLUSION: Pyridoxine may reduce the need for capecitabine dose modifications and the incidence of severe HFS, but does not impact on antitumour effect. |
