The Inverse Association between the Baseline Renal Function and Overall Survival in Patients with Metastatic Renal Cell Carcinoma Treated with Molecular-Targeted Agents

The Inverse Association between the Baseline Renal Function and Overall Survival in Patients with... Background: The objective of this study was to investigate the prognostic significance of the baseline renal function in metastatic renal cell carcinoma (mRCC) patients treated with molecular-targeted agents. Patients and Methods: This study included 408 consecutive mRCC patients receiving molecular-targeted therapy, consisting of 124 patients in group A and 284 patients in group B who had baseline estimated glomerular filtration rates ≥ 60 ml/min/1.73 m<sup>2</sup> and < 60 ml/min/1.73 m<sup>2</sup>, respectively. Results: Compared with group A, group B was significantly less likely to have poor prognostic factors, such as a high proportion of patients without nephrectomy. The median overall survivals (OSs) after the initiation of targeted therapy in groups A and B were 21.4 and 35.8 months, respectively, and there was a significant difference in the OS between the 2 groups. However, multivariate analysis showed a lack of independent impact of the baseline renal function on the OS. Furthermore, when patients without a nephrectomy were excluded, no significant difference was noted in the OS between the 2 groups. Conclusion: These findings suggested that there was no adverse impact of an unfavorable baseline renal function on the efficacy of targeted agents against mRCC. Thus, molecular-targeted therapy should not be avoided in mRCC patients with an impaired baseline renal function. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Current Urology Karger

Abstract

Background: The objective of this study was to investigate the prognostic significance of the baseline renal function in metastatic renal cell carcinoma (mRCC) patients treated with molecular-targeted agents. Patients and Methods: This study included 408 consecutive mRCC patients receiving molecular-targeted therapy, consisting of 124 patients in group A and 284 patients in group B who had baseline estimated glomerular filtration rates ≥ 60 ml/min/1.73 m<sup>2</sup> and < 60 ml/min/1.73 m<sup>2</sup>, respectively. Results: Compared with group A, group B was significantly less likely to have poor prognostic factors, such as a high proportion of patients without nephrectomy. The median overall survivals (OSs) after the initiation of targeted therapy in groups A and B were 21.4 and 35.8 months, respectively, and there was a significant difference in the OS between the 2 groups. However, multivariate analysis showed a lack of independent impact of the baseline renal function on the OS. Furthermore, when patients without a nephrectomy were excluded, no significant difference was noted in the OS between the 2 groups. Conclusion: These findings suggested that there was no adverse impact of an unfavorable baseline renal function on the efficacy of targeted agents against mRCC. Thus, molecular-targeted therapy should not be avoided in mRCC patients with an impaired baseline renal function.
