OBJECTIVE: To evaluate the outcomes following targeted therapies in the management of metastatic renal cell carcinoma (mRCC), through the study of overall survival (OS) and progression-free (PFS).
PATIENTS AND METHODS: We retrospectively included 78 patients treated with targeted therapies for mRCC at the Paul Papin Cancer Institute from 2004 to 2009. Overall survival (OS), progression free survival (PFS), response to treatment, occurrence of grade III and IV side effects, were analyzed following first and second line treatments.
RESULTS: Median follow-up was 33 months [5-236], and 41 patients died (52.6%). Median OS was 36 months [95% CI 29-43]. The median PFS was 14 months [95% CI 6.71-21.29] for sunitinib, 38 months [95% CI 11.41-64.59] for bevacizumab with interferon (IFN), and 8 months [95% CI 0-17.03] for IFN alone. A partial reduction, stabilization or increase in tumor size was observed for 19.2%, 47.4% and 25.6% of cases. A second line treatment was given for 53 patients. They received either sunitinib (n=20, 37.8%), bevacizumab with IFN (n=7, 13.2%), sorafenib (n=17, 32.2%), temsirolimus (n=3, 5.6%) or other molecules (n=6 11.2%). Grade III or IV side effects were observed for 14.1%, 28.3% and 18.2% of the patients following first, second and third line treatment, respectively.
CONCLUSION: Outcomes of targeted therapies in our center upheld the literature data. These therapies allow a benefit survival versus immunotherapy, with sometimes large side-effect.
