ABSTRACT
BACKGROUND:
The prognostic significance of number and location of organ-specific metastatic sites in treated metastatic clear cell renal carcinoma (ccmRCC) patients is object of debate. The current study aimed to test the association between number and location of organ-specific metastatic sites and overall survival (OS) in ccmRCC. MATERIALS ANDMETHODS:
Within Surveillance, Epidemiology and End Results database (2010-2018), all ccmRCC patients treated with cytoreductive nephrectomy and/or systemic therapy were identified. Kaplan-Meier plots and Cox regression models focused on A). number of organ-specific metastatic sites solitary vs. 2 vs. 3 or more; B). solitary organ-specific metastatic sites (lung vs. bone vs. liver vs. brain); C). combinations of 2 and 3 or more different organ-specific metastatic sites.RESULTS:
Of 4,527 patients (median OS 19 months), 3,054 (67%) harbored solitary organ-specific metastatic sites (27 months) vs. 1,153 (25%) combinations of 2 different organ-specific metastatic sites (12 months) vs. 320 (8%) combinations of 3 or more different organ-specific metastatic sites (7 months). In patients with solitary organ-specific metastatic sites, bone metastases portended the longest median OS (median OS 31 months) vs. liver metastases portended the shortest median OS (16 months). Both were independent predictors of OS (multivariable hazard ratio, bone 0.87; liver 1.21). Median OS was similarly poor in patients with combinations of 2 different organ-specific metastatic sites (9-13 months), regardless of their location. The same pattern applied to patients with combinations of 3 or more different organ-specific metastatic sites (6-7 months).CONCLUSIONS:
Solitary organ-specific metastatic sites portend the most favorable OS (16-31 months). Solitary bone metastases yield the longest vs. liver metastases the shortest OS. Invariably poor OS applies to combinations of 2 (9-13 months), as well as 3 or more different organ-specific metastatic sites (6-7 months), regardless of their location.Palabras clave
