2/1 schedual Sunitinib better than 4/2, says study
The Alternative 2/1 Schedule of Sunitinib is Superior to the Traditional 4/2 Schedule in Patients With Metastatic Renal Cell Carcinoma: A Meta-analysis.
patients with metastatic renal cell carcinoma (mRCC). Studies were retrieved from Medline, Cochrane Central, Scopus, Embase, and Web of Science databases. Data were extracted and pooled as hazard ratio (HR: survival data) or odds ratio (OR: dichotomous data) using Comprehensive Meta-analysis software. Based on data of 1173 patients, the progression-free survival (HR, 0.52; 95% confidence interval [CI], 0.39-0.95; P < .0001), overall survival (HR, 0.6; 95% CI, 0.43-0.85; P < .0001), and stable disease rates (OR, 0.38; 95% CI, 0.19-0.76; P = .006) were significantly improved on the alternative 2/1 schedule, compared with the traditional 4/2 schedule. However, the complete response (OR, 1.32; 95% CI, 0.34-5.22; P = .69) and partial response (OR, 1.34; 95% CI, 0.44-4.14; P = .61) rates were comparable between the 2 regimens. The tolerability of the alternative 2/1 schedule was superior to the traditional one as investigated adverse events like fatigue (OR, 2.91; 95% CI, 1.89-4.46; P < .0001), hypertension (OR, 2.08; 95% CI, 1.56-2.75; P < .0001), and diarrhea (OR, 2.18; 95% CI, 1.19-3.98; P = .012) were significantly less common. In conclusion, the alternative 2/1 sunitinib schedule provides improved tolerability and survival in patients with mRCC. Large randomized trials with long follow-up periods are required to validate and confirm these findings.
