The prognostic stratification of poor risk mRCC patients in the era of targeted therapy represents an unmet medical need. We analyzed, individually, each prognostic factor included in modified Memorial Sloan-Kettering Cancer Center (MSKCC) and Heng criteria to investigate their prognostic relevance in poor risk mRCC patients and proposed a model to stratify poor risk patients into 3 separate subgroups.


Data were collected from 20 Italian and 2 Spanish centers. Overall survival (OS) was estimated using Kaplan-Meier method. Hemoglobin, Performance Status, Thrombocytosis, Neutrophilia, Number of metastatic sites, Time from diagnosis to treatment, LDH and Hypercalcemia, according to modified MSKCC and Heng criteria, were included in the Cox analysis.


239 (151 males; 205 clear cell) poor risk mRCC pts were enrolled according to, at least, three of MSKCC, or modified MSKCC or Heng criteria. 233 pts were treated with a first line therapy (56 pts with temsirolimus, 163 pts with tyrosine kinase inhibitors (TKI), 14 pts with other agents); 101 pts with a second line (50 everolimus, 49 TKI, 2 other agents) and 31 pts with a third line ( 4 everolimus; 20 TKI, 7 other agents). Only Hemoglobin (13 vs 8 months; p = 0.005), Performance Status (14 vs 7 months; p = 0.002), and Time from diagnosis to treatment (22 vs. 8 months; p < 0.001) were predictors of short survival, independently from the presence/absence of the other prognostic factors. We identified three risk categories: the favorable-poor risk group (0-1 of previous confirmed three prognostic factors; 45 pts) in which median OS (mOS) was 20 months; the intermediate-poor risk group (2 prognostic factors; 111 pts) in which mOS was 11 months and the poor-poor risk group (3 prognostic factors; 81 pts) in which mOS was 5 months (p < 0.001).


This is the first study that identifies three different prognostic subgroups among poor risk RCC patients. Kaplan Meier survival curves of each subgroup will be presented during the meeting.
