Key clinical point: In patients with early-stage triple-negative breast cancer (TNBC), capecitabine improved survival and demonstrated a tolerable safety profile, with lower dosage, higher frequency, and adjuvant setting being related with better survival outcomes.
Major finding: Capecitabine vs chemotherapy without capecitabine improved disease-free survival (DFS; hazard ratio [HR] 0.77; P < .001) and overall survival (HR 0.73; P < .0001). A lower dose (<1000 mg; HR 0.69; P = .002), a higher dosage frequency (≥6 cycles; HR 0.72; P < .0001) and an adjuvant setting (HR 0.74; P < .0001) were associated with a higher DFS. Capecitabine was associated with higher risk for diarrhea ( P < .0001), hand-foot syndrome ( P < .0001), and leukopenia ( P < .01).
Study details : Findings are from a meta-analysis of 11 phase 3 randomized controlled trials including 5175 female patients with early-stage TNBC who received neoadjuvant or adjuvant chemotherapy with or without capecitabine.
