Delayed Cytoreductive Nephrectomy Following Three Years of Targeted Therapy for Metastatic Renal Cell Carcinoma.

ABSTRACT: We present a 55-year-old male, with good performance status who was diagnosed with a case of metastatic renal cell carcinoma following a pathologic femur fracture. Despite good performance status, multifocal metastases and poor-prognostic features portended a grim prognosis with predicted overall survival of less than nine months. On initial presentation, he was excluded from cytoreductive nephrectomy based on brain metastasis and interleukin-2 was not pursued as the primary tumor was to be left in situ. The patient was reconsidered for cytoreductive nephrectomy after sustained response to fifth line targeted therapies with shrinkage of tumor burden. The post-operative course was uneventful and the patient was discharged home on postoperative day one. Temsirolimus was resumed one week after surgery and the patient reported returning to his normal activities at the two week follow-up visit. We highlight important clinical features of metastatic renal cell carcinoma, the surgical considerations for cytoreductive nephrectomy and the detailed multidisciplinary care the patient received throughout this case report.

Project description:BackgroundThe metastatic renal cell carcinoma (mRCC) patients treated with upfront cytoreductive nephrectomy combined with α-interferon yields additional overall survival (OS) benefits. It is unclear whether mRCC patients treated with vascular endothelial growth factor receptor-tyrosine kinase inhibitor (VEGFR-TKI) will benefit from such cytoreductive nephrectomy either. The aim of the study was to identify variables for selection of patients who would benefit from upfront cytoreductive nephrectomy for mRCC treated with VEGFR-TKI.MethodsClinical data on 74 patients enrolled in 5 clinical trials conducted in Cancer Hospital (Institute), Chinese Academy of Medical Sciences from January 2006 to January 2014 were reviewed retrospectively. The survival analysis was performed by the Kaplan-Meier method. Comparisons between patient groups were performed by Chi-square test. A Cox regression model was adopted for analysis of multiple factors affecting survival, with a significance level of α = 0.05.ResultsFifty-one patients underwent cytoreductive nephrectomy followed by targeted therapy (cytoreductive nephrectomy group) and 23 patients were treated with targeted therapy alone (noncytoreductive nephrectomy group). The median OS was 32.2 months and 23.0 months in cytoreductive nephrectomy and noncytoreductive nephrectomy groups, respectively (P = 0.041). Age ≤45 years (P = 0.002), a low or high body mass index (BMI <19 or >30 kg/m2) (P = 0.008), a serum lactate dehydrogenase (LDH) concentration >1.5 × upper limit of normal (P = 0.025), a serum calcium concentration >10 mg/ml (P = 0.034), and 3 or more metastatic sites (P = 0.023) were independent preoperative risk factors for survival. The patients only with 0-2 risk factors benefited from upfront cytoreductive nephrectomy in terms of OS when compared with the patients treated with targeted therapy alone (40.0 months vs. 23.2 months, P = 0.042), while those with more than 2 risk factors did not.ConclusionsFive risk factors (age, BMI, LDH, serum calcium, and number of metastatic sites) seemed to be helpful for selecting patients who would benefit from undergoing upfront cytoreductive nephrectomy.
