Abstract

Background

In recent years, TTs have improved the prognosis of mRCC patients (pts). Despite a not negligible number of pts received 3 TTs in clinical practice, no TTs have been evaluated as 3rd line. Aim of this study is to investigate the clinical outcome in pts who received 3 TTs.

Patients and methods

Pts with clear-cell mRCC who received 3 TTs were included. A questionnaire was sent to main Italian centers involved in the treatment of mRCC. Demographic data, history of RCC, type and length of first, second and third line were collected; MSKCC risk class was calculated before starting the 1st and 3rd lines, Heng class before the 3rd line. Sequences of class and specific TTs were evaluated: TKIàTKIàmTOR and TKIàmTORàTKI or sunitinib (SU)-sorafenib(SO)- everolimus(EV) and SU-EV-SO. Median PFS, OS and Time to Strategy Failure (TTSF: from start of 1st to end of 3rd line) were estimated with the Kaplan-Meyer method with 95% CI and curves were compared with log-rank test. The study had the ethical approval.

Results

1905 pts were screened and 252 pts (13%) were treated with 3 TTs. The median age was 60 yrs (range 52–68), 73% were male, 96% underwent nephrectomy and 38% were metastatic at diagnosis. At 1st line, the Motzer class was good, intermediate, and poor in 48%, 47% and 5% of pts, respectively. PFS for type and line of therapy are reported in the table below. The TTSF was 36.4 (30.5–42.2) vs. 30.6 (26.5–34.6) mos (p = 0.11), and the OS was 52.1 (41.6–62.6) vs. 36.3 (31.2–41.4) mos (p = 0.01), for TKIàTKIàm-TOR and and TKIàm-TORàTKI, respectively. TTSF for SU-SO-EV was 36.5 vs. 30.4 mos for SU-EV-SO (p = 0.011). When stratified by ECOG-PS before 3rd line or baseline MSKCC, TS maintained its independent prognostic role (p = 0.002 and p = 0.004, respectively).

Conclusions

Only few patients received 3 lines of TTs. The sequence sunitinib-sorafenib-everolimus was associated with a better TTSF and OS as compared to the sequence sunitinib-everolimus-sorafenib.
