Abstract:
623 Background: Treatment of mRC is not affected by gender, studying possible differences in a real-world study, could increase the knowledge of toxicity and possible prognostic factors. Methods: SPAZO2 (NCT03091465) was a retrospective real-world study to analyze the effectiveness of 1st-line pazopanib and subsequent therapies in mRC. Data from 530 pt treated outside CT were collected in 50 spanish centers, and externally monitored. Ineligibility criteria: ECOG 〉 1, pure nonclear-cell, Hgb 〈 9 g/dl, renal failure, severe cardiovascular disease, chronic liver disease, or recent neoplasia Results: 530 pt were included, 67.2% men (M), mean age was 66.2 years (26-92). There were no significant differences (M vs W) in the age 〉 75 (24.7 vs 24.1%), clear cell carcinoma (77.2 vs 79.9%), nephrectomy (72.5 vs 68.4%), IMDC (favourable: 15.2 vs 12.1%, intermediate: 59.3 vs 64.4%, poor: 25.6 vs 23.6%), metastases (lymph nodes: 46.1 vs 43.1%, lung: 69,7 vs 67,2 %, liver: 16 vs 20.1%, bone: 27 vs 24.1%, skin/soft tissues: 1.1 vs 3,4% and CNS: 4,8% vs 6.3%). Discontinuation due to toxicity or comorbidities was 12.4 vs 9.8%. There were no differences in the second lines received (57.9 vs 56.9%), neither response, PFS and OS (table). Median follow up was 39 mo. The gender has no prognostic value when adjusted for the prognostic groups of IMDC (HR of PFS 0.96, CI 95% 0.78-1.2, HR of OS: 0.92, CI 95% 0.72-1.14). Only diarrhea and elevation of uric acid were higher in the men group. Conclusions: Pazopanib was safe and effective in both groups with similar outcome. Women had less diarrhea and less increased uric acid. There were not differences in OS or PFS. In IMDC subgroup analysis, there is a trend towards a better evolution or PFS in the poor prognosis women subgroup. Clinical trial information: NCT03091465. [Table: see text]
