Popis: Abstract: Purpose: Capecitabine is commonly used as a first-line treatment for gastrointestinal (GI) tract cancers. Common toxicities of capecitabine include diarrhea and hand-foot syndrome (HFS), which frequently lead to dose reduction, interruption, and even discontinuation. While racial and ethnic differences in capecitabine toxicities have been suggested by case reports, they have not been systematically evaluated in diverse ‘real-world’ populations. This study examined differences in capecitabine-related diarrhea, HFS, dose-reduction, and discontinuation among patients of different racial and ethnic backgrounds. Methods: In this retrospective chart review study, the electronic medical records of patients receiving first-line capecitabine-containing regimens for GI malignancies were reviewed. Patients on regimens containing irinotecan or radiation were excluded due to overlapping toxicities. Concurrent non-neoplastic medications were also recorded. Multiple logistic regression models were used to test for an association between race/ethnicity with any capecitabine toxicities while adjusting for other demographic characteristics. Results: One hundred twenty-five patients diagnosed with either colon [N=76 (60.8%)], rectal [N=22 (17.6%)], gastric [N=16 (12.8%)], or other GI cancers [N=11 (8.8%)] were included. In logistic regression analysis, diarrhea occurrence was significantly lower in the African-American/non-Hispanic [OR(95% CI): 0.25 (0.08, 0.75) p value Citation Format: Soham D.
