Abstract 1028
Background
IMDC classifies patients (pt) with mRCC in favorable, intermediate or poor-risk (FR, IR, PR). IR pt having 1 vs 2 unfavorable factors (IR1 vs IR2) treated with sunitinib in clinical trials, have different outcomes (Rini, ASCO 2017). Outcomes are also better foreligible vs ineligible pt for clinical trials (E vs I, Arranz, ESMO 2017).We compare IR1 vs IR2 in I vs E pt receiving 1stPz, and validate the IMDC-modified models.
Methods
SPAZO2 (NCT03091465) retrospectively analyzed the real-world effectiveness of 1stPz in mRCC in 530 pt from 50 centers in Spain. Data were externally monitored. Median follow-up was 39 months (mo). No pt received Nivo or Cabo as 2nd-line.
Results
Among the 323 pt classified as IR1 (53%) or IR2 (47%), we found differences (p < 0.05) in mean age (64 vs 68 y), prior nephrectomy (80 vs 65%), ECOG 0-1 (98 vs 93%), Hb 954PORR (%) Median PFS (mo) Median OS (mo) E I E I E I FR 63 47 23.5 13.5 42.3 29.0 IR1 45.9 37.5 11.0 14.7 26.4 24.1 IR2 21.6 14.3 10.0 7.9 18.0 14.8 PR 33 16 7.5 5.2 14.2 5.9
Conclusions
In our real-world study before Nivo/Cabo approval for 2nd-line, pt with IR1 had statistically significant better ORR and longer OS than IR2. The discrimination power of the IMDC model can be improved by subclassifying patients of the intermediate group and eligibility for clinical trials.
