Abstract

Aim: We investigated the association of biological sex with the incidence of inter-cycle treatment delays. Patients & methods: This retrospective cohort study included patients receiving first-line chemotherapy. Multivariable logistic regression was used to assess the association between biological sex and a 7-day treatment delay, adjusting for confounders. Results: Among 1904 patients, 1106 (58%) were males and 798 (42%) females. 387 patients (20%) had a treatment delay (54% males, 46% females; p = 0.08). Sex was associated with treatment delays in multivariable analysis (males vs females OR: 0.73, 95% CI 0.57–0.93). Conclusion: The findings are concordant with other studies reporting differences in toxicity profiles of fluorouracil. Further research is required to optimize dosing between males and females.
