ABSTRACT
INTRODUCTION:
Pazopanib is a standard first-line treatment for metastatic clear-cell renal cell carcinoma (ccRCC). Very few data on its activity in non-clear-cell renal cell carcinoma (nccRCC) are currently available. The aim of this study was to retrospectively analyze efficacy and toxicity of pazopanib in nccRCC patients. PATIENTS ANDMETHODS:
Records from advanced nccRCC patients (consecutive sample) treated with first-line pazopanib between 2010 and 2015 at 17 Italian centers were reviewed. Response rate, progression-free survival (PFS), and overall survival (OS) were evaluated. Univariate and descriptive analyses were performed.RESULTS:
Thirty-seven patients with nccRCC were treated with first-line pazopanib; 51% had papillary histology, 24% chromophobe, 22% unclassified, and 3% had Xp11.2 translocation. Dose reductions/temporary interruptions for toxicity were required in 46% of cases. Grade (G) 3/4 toxicity was seen in 32%, G1/2 in 89% of cases; 81% achieved disease control, with 10 partial responses (27%) and 20 cases of stable disease (54%); 16% of patients had disease progression as best response. Median PFS and OS were 15.9 and 17.3 months, respectively. In univariate analysis, nephrectomy (P = .020), Memorial Sloan Kettering Cancer Center (MSKCC) score (P < .001), basal neutrophil/lymphocyte ratio (NLR; P = .009) and performance status (PS) (P = .001) were associated with PFS; MSKCC score (P < .001), International Metastatic Renal Cell Carcinoma Database Consortium score (P = .003), PS (P < .0001), nephrectomy (P = .002), histology (P = .035), dose reductions/interruptions (P = .039), best response to treatment (P < .001), and NLR (P = .008) were associated with OS.CONCLUSION:
In nccRCC patients, treatment with pazopanib was effective and feasible; dose reductions required for toxicity were similar as expected in ccRCC.Palavras-chave
