Abstract
Background
Among patients with colorectal cancer (CRC) treated with oxaliplatin (L-OHP)-based chemotherapy, delayed chemotherapy-induced nausea and vomiting (CINV) have not been well controlled.
Methods
We pooled data from two prospective observational studies in Japan and one phase III clinical trial to assess whether delayed CINV could be controlled with a combination of three antiemetics adding a neurokinin-1 receptor antagonist and identified individual risk factors, using an inverse probability treatment-weighted analysis.
Results
A total of 661 patients were evaluable in this study (median age: 64 years; 391 male, and 270 female). 3 antiemetics controlled delayed nausea (33.18% vs. 42.25%; p = 0.0510) and vomiting (4.15% vs. 16.08%; p < 0.0001) better than with 2 antiemetics. Female and 2 antiemetics were risk factors for both delayed nausea (female—odds ratio [OR]: 1.918; 95% confidence interval [CI]: 1.292–2.848; p = 0.0012; 2 antiemetics—OR: 1.485; 95% CI: 1.000–2.204; p = 0.0498) and delayed vomiting (female—OR: 2.735; 95% CI: 1.410–5.304; p = 0.0029; 2 antiemetics—OR: 4.551; 95% CI: 2.116–9.785; p = 0.0001).
Conclusions
Identifying individual risk factors can facilitate personalized treatments for delayed CINV. We recommend a 3-antiemetic combination prophylaxis for CRC patients treated with L-OHP-based chemotherapy, especially for female patients.
