Summary of "Long survival of patients with metastatic clear cell renal cell carcinoma. Results of real life study of 344 patients."

The treatment landscape in metastatic renal cell carcinoma has changed fundamentally over the last decade by the development of anti-angiogenic agents, mTOR inhibitors, and immunotherapy. Outside of the context of a clinical trial the treatments are used sequentially. We describe results under real life conditions of a sequential treatment strategy, before the era of immunotherapy. All patients were treated according to their prognostic score (either MSKCC or IMDC) for advanced renal cell carcinoma. A treatment strategy involving 1 to 4 lines was determined including a rechallenge criterion for the repeat use of a treatment class. 344 patients were included over 3 years. Overall survival was 57 months in patients with good or intermediate prognosis and 19 months in patients with poor prognosis. In the former group, the proportions of patients treated with 2 to 4 treatment lines were 70%, 38% and 16% respectively. The best objective response rates for lines 1 to 4 were 46%, 36%, 16% and 17% respectively. Grade III/IV toxicity did not appear to be cumulative. The recommended strategy was followed in 68% of patients. A large proportion of patients with good or intermediate prognosis who progress after two lines of treatment still have a performance status good enough to receive a systemic treatment, which justifies such a strategy. Overall survival of patients with good and intermediate prognosis was long, suggesting a benefit from the applied approach. These results might be used as selection criterion for the treatment of patients in the era of immune checkpoint inhibitors. This article is protected by copyright. All rights reserved.

Medical and Biotech [MESH] Definitions

A heterogeneous group of sporadic or hereditary carcinoma derived from cells of the KIDNEYS. There are several subtypes including the clear cells, the papillary, the chromophobe, the collecting duct, the spindle cells (sarcomatoid), or mixed cell-type carcinoma.

Persons who have experienced prolonged survival of HIV infection. This includes the full spectrum of untreated, HIV-infected long-term asymptomatics to those with AIDS who have survived due to successful treatment.

Mucocellular carcinoma of the ovary, usually metastatic from the gastrointestinal tract, characterized by areas of mucoid degeneration and the presence of signet-ring-like cells. It accounts for 30%-40% of metastatic cancers to the ovaries and possibly 1%-2% of all malignant ovarian tumors. The lesions may not be discovered until the primary disease is advanced, and most patients die of their disease within a year. In some cases, a primary tumor is not found. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d ed, p1685)

A rare tumor of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognized: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumor (called also ENDODERMAL SINUS TUMOR and yolk sac tumor), occurring chiefly in children. The latter variety may also arise in the testis. (Dorland, 27th ed)

A carbonic anhydrase and transmembrane protein that consists of an N-terminal PROTEOGLYCAN-like domain, a catalytic region, a single-pass transmembrane domain, and a short intracellular tail. It functions as a dimer and is expressed primarily by cells of the GASTROINTESTINAL TRACT; BILE DUCT EPITHELIUM; and GALL BLADDER. It is expressed at high levels in many solid tumors, especially CLEAR CELL RENAL CARCINOMA, in response to CELL HYPOXIA.
