Chemotherapy Dose Intensity and Overall Survival Among Patients With Advanced Breast or Ovarian Cancer

Abstract

Dose delays, dose reductions, and reduced RDI were common. In advanced breast cancer, health status and triple-negative disease were significantly associated with mortality. In advanced ovarian cancer, dose reductions and tumor histology were significantly associated with mortality. These results can help identify potential risk factors and characterize the effect of chemotherapy dose modification strategies on mortality.
