ABSTRACT
OBJECTIVE: To assess the prognostic value of clinical and biological features in patients treated with second-line targeted therapies (TT) for a metastatic renal cell carcinoma (mRCC). MATERIAL AND METHODS: A retrospective study was performed including 60 patients treated with second-line TT from 2006 to 2013. Clinical and biological features were collected, including TT-induced toxicities, Heng and MSKCC prognostic scores, and renal function. Overall survival (OS) and progression-free survival (PFS) were assessed using univariate and multivariate analysis. RESULTS: The median age was 61 years [39-81]. MSKCC and Heng scores were significantly prognostic for OS and PFS (P<0.05). Hypo-albuminemia, anemia and brain metastasis were associated with poorer OS and PFS (P<0.05). Severe induced toxicities had a prognostic impact with higher OS (26 months vs 10 months, P=0.003) and PFS (5 months vs 4 months, P=0.047). Renal function impairment at the initiation of the second line was also associated with higher survival (OS=24 months vs 9 months, P=0.035 and PFS=7 months vs 4 months, P=0.043). On multivariate analysis, induced toxicity was found as an independent factor of good prognosis for OS (HR=0.36; P=0.01). CONCLUSION: Our results suggested that renal function impairment and TT-induced toxicities in the second line of treatment for mRCC have a potential prognostic interest as it had previously been reported for the first line of TT. LEVEL OF EVIDENCE: 5.

Desmoplastic small round cell tumor (DSRCT) is a very rare but aggressive malignancy. It is usually observed in males during adolescent and early adulthood. The tumor primarily affects the intra-abdominal serosal and is characterized by distinctive histological and immunophenotypic features and by the specific reciprocal translocation EWS-WT1. Prognosis is mainly poor with a mean survival approximately of 2.5 years. However, long-term survivals have been reported using aggressive multimodal therapy based on complete surgical excision, systemic chemotherapy and radiotherapy. The addition of hyperthermic intraperitoneal chemotherapy in the multimodal approach has been reported in very few cases but no effect on survival has been clearly demonstrated. We report a case of a 51-year old adult patient presenting with a DSRCT treated with aggressive therapy based on systemic chemotherapy, complete cytoreductive surgery associated with hyperthermic intraperitoneal chemotherapy, resulting in a long term survival of 4 years.
