Abstract: Breast cancer is the most common cancer in women worldwide. Doxorubicin-based chemotherapy is used to treat breast cancer patients; however, neutropenia is a common hematologic side effect and can be life-threatening. The ABCB1 and SLC22A16 genes encode proteins that are essential for doxorubicin transport. In this study, we explored the effect of 2 common polymorphisms in ABCB1 (rs10276036 C/T) and SLC22A16 (rs12210538 A/G) on the development of grade 3/4 febrile neutropenia in Iranian breast cancer patients. Our results showed no significant association between these polymorphisms and grade 3/4 febrile neutropenia; however, allele C of ABCB1 (rs10276036 C/T) (p = 0.315, OR = 1.500, 95% CI = 0.679–3.312) and allele A of SLC22A16 (rs12210538 A/G) (p = 0.110, OR = 2.984, 95% CI = 0.743–11.988) tended to have a greater association with grade 3/4 febrile neutropenia, whereas allele T of ABCB1 (rs10276036) (p = 0.130, OR = 0.515, 95% CI = 0.217–1.223) and allele G of SLC22A16 (rs12210538) (p = 0.548, OR = 0.786, 95% CI = 0.358–1.726) tended to protect against this condition. In addition to breast cancer, a statistically significant association was also observed between the development of grade 3/4 febrile neutropenia and other clinical manifestations such as stage IIIC cancer (p = 0.037) and other diseases (p = 0.026). Our results indicate that evaluation of the risk of grade 3/4 neutropenia development and consideration of molecular and clinical findings may be of value when screening for high-risk breast cancer patients.
