Prognostic Effect of Preoperative Apolipoprotein B Level in Surgical Patients with Renal Clear Cell Carcinoma

Background: To assess the prognostic value of preoperative apolipoprotein B level in surgical patients with renal clear cell carcinoma (ccRCC). Materials and Methods The study included 307 ccRCC patients receiving radical or partial nephrectomy between 2003 and 2012 in our center. The correlations among the preoperative ApoB, clinico-pathological parameters, and overall survival (OS) were evaluated. Results A total of 193 men (62.9%) and 114 women (37.1%) with ccRCC underwent radical or partial nephrectomy were enrolled in the present study. The OS at five years after operation was 90.6% for all patients, 87.4% for the lower ApoB group, and 97.0% for the higher ApoB group. The CSS at 5 years after surgery was 90.2% for all patients, 86.7% for the lower ApoB group, and 97.0% for the higher ApoB group. A higher ApoB level was related to a better OS and CSS in ccRCC patients (P = 0.001 and P 60 (P=0.008 and P=0.023), lower Apo B level (P= 0.019 and P= 0.018), were independent prognostic factors for OS and CSS, respectively. Conclusions In the Apo apolipoprotein family, the preoperative ApoB level has an important clinical significance for predicting the prognosis survival rate of the ccRCC patients.
