It is now widely approved for the first-line treatment of advanced RCC. A prognostic marker is required for selecting patients who will benefit most from sunitinib. We have previously revealed that pretreatment normal C-reactive protein (CRP) predicts better oncological outcomes of sunitinib. However, CRP kinetics of sunitinib have never been described. In the cytokine era, CRP kinetics have an impact on survival in patients with metastatic RCC. As such, in the present study, we evaluate CRP kinetics in advanced RCC patients treated with sunitinib. METHODS Between December 2008 and July 2012, 52 consecutive patients with advanced RCC who were treated with sunitinib, were enrolled. Patients divided into 3 groups according to the pretreatment CRP level and CRP kinetics: (i) normal CRP cohort; defined as pretreatment CRP levels ≤ 0.30 mg/dL, (ii) normalized CRP cohort; defined as pretreatment CRP > 0.30 mg/dL and normalized CRP within 2 cycles of treatment, (iii) non-normalized CRP cohort; defined as pretreatment CRP > 0.30 mg/dL and not normalized CRP after the initiation of sunitinib. Disease control rates, non-parametiric estimates of progression-free survival time and overall survival time were evaluated. RESULTS The normal CRP cohort comprised 16 patients (30.8%), the normalized CRP cohort comprised 8 patients (15.4%), and the non-normalized CRP cohort comprised 28 patients (53.8%). Disease control rates of the normal, normalized, and non-normalized CRP cohorts were 93.8%, 75.0%, and 32.1%, respectively. The normal and normalized CRP cohorts showed statistically significant better disease control rates than the non-normalized CRP cohort (P = 0.0003). The normal CRP cohort showed significantly longer progression-free survival time than the non-normalized CRP cohort (median 19.0 months vs 5.0 months, P = 0.0023). Also, the normal CRP cohort showed significantly longer overall survival time than the non-normalized CRP cohort (median 30.0 months vs 9.0 months, P = 0.0012). CONCLUSIONS CRP revealed prognostic significance in advanced RCC patients treated with sunitinib. Pretreatment CRP level could be a useful prognostic marker for sunitinib effectiveness. And a decrease of CRP level during sunitinib treatment predicts better response. CRP kinetics is a prognostic indicator as well as pretreatment CRP level for patients with advanced RCC treated with sunitinib. © 2013 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 189Issue 4SApril 2013Page: e788 Advertisement Copyright & Permissions© 2013 by American Urological Association Education and Research, Inc.MetricsAuthor Information Tetsuo Fujita Kanagawa, Japan More articles by this author Masatsugu Iwamura Kanagawa, Japan More articles by this author Takahiro Hirayama Kanagawa, Japan More articles by this author Daisuke Ishii Kanagawa, Japan More articles by this author Ken-ichi Tabata Kanagawa, Japan More articles by this author Kazumasa Matsumoto Kanagawa, Japan More articles by this author Kazunari Yoshida Kanagawa, Japan More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
