The purpose of this study is to compare the outcomes of first-line systemic targeted therapy (TT) and immunotherapy (IT) in patients with metastatic renal cell carcinoma (mRCC).
This study was a retrospective review of the data of 262 patients treated with systemic IT or TT with tyrosine kinase inhibitors between 2003 and 2013.
The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were assessed using RECIST v1. 0 criteria and the Kaplan-Meier method with log-rank test.
During the median 4. 3-month treatment and the 24-month follow-up period, the ORR/PFS/OS of the overall first-line and second-line therapy were 41. 9%/8. 1months/16. 8months and 27. 5%/6. 5months/15. 3months, respectively. The first-line TT/IT/sequential IT had a PFS of 9. 3/6. 4/5. 7 months and an OS of 15. 8/16. 5/40. 6 months (all p < 0. 05). The second-line of TT/IT had a PFS of 7. 1/2. 1 months (both p < 0. 05) and an OS of 16. 6/8. 6 months (p = 0. 636), respectively. Pazopanib provided the best median PFS of 11. 0 months (p< 0. 001) and a quadruple IT regimen had a superior PFS (p= 0. 522). For OS, sequential treatment with IT and TT was superior compared to treatment with either IT or TT alone (40. 6/16. 5/15. 8 months; p=0. 014). The prognosis according to the MSKCC model showed that favorable/intermediate/poor risk groups had a PFS of 8. 5/10. 4/2. 3 months, and an OS of 43. 1/20. 4/5. 6 months, respectively. The prognosis calculated using the Heng model showed that the favorable/intermediate/poor risk groups had a PFS of 9. 2/3. 9/2. 7months, and an OS of 32. 4/16. 5/6. 1months, respectively (all p<0. 001).
In patients with mRCC, TT provided a better PFS and OS compared with IT.
