Objectives:
We examined the population-based rates of cancer-specific survival in patients with metastatic renal cell carcinoma (MRCC) treated with either partial (PN) or radical cytoreductive nephrectomy (RN).
Methods:
Patients diagnosed with MRCC and treated with either PN or RN were identified within nine SEER cancer registries. Matched and unmatched Kaplan-Meier survival analyses, as well as multivariable Cox regression models compared the effect of RN (n = 1997, 97.8%) vs. PN (n = 46, 2.2%) on cancer-specific survival (CSS). Covariates consisted of age, gender, community type (rural vs urban), race, Surveillance, Epidemiology, and End Results (SEER) registry, tumor size and year of diagnosis.
Results:
In multivariable unmatched Cox regression analyses, no statistically significantly difference was found in CSS between the two groups (hazard ratio [HR] 1.40, P = .16). Similarly, no difference in CSS was found in the matched analyses (HR 1.35, log rank P = .34).
Conclusion:
Cytoreductive PN does not appear to undermine survival in patients with MRCC.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
