Overexpression of G6PD Represents a Potential Prognostic Factor in Clear Cell Renal Cell Carcinoma

Abstract Background: Several models and markers were developed and found to predict outcome of advanced renal cell carcinoma. This study aimed to evaluate the prognostic value of the ratio of maximum to minimum tumor diameter (ROD) in metastatic clear cell renal cell carcinoma (mccRCC).Methods: Patients with mccRCC (n=213) treated with sunitinib from January 2008 to December 2018 were identified. Cut-off value for ROD was determined using receiver operating characteristic. Patients with different ROD scores were grouped and evaluated. Survival outcomes were estimated by Kaplan-Meier method.Results: The optimal ROD cutoff value of 1.34 was determined for progression free survival (PFS) and overall survival (OS). Patients in ROD≥1.34 group had shorter PFS (9.6 versus 17.7 months, p<0.001) and OS (25.5 versus 32.6 months, p<0.001) than patients in ROD<1.34 group. After adjustment for other factors, multivariate analysis showed ROD≥1.34 was an independent prognostic factor for PFS (p<0.001) and OS (p=0.006). Patients in ROD³1.34 group presented higher proportions of T3/4 stage (92.9% versus 7.1%, p=0.012), WHO/ISUP grade III/IV (72.0% versus 28.0%, p=0.010), tumor necrosis (71.0% versus 29.0%, p=0.039), sarcomatoid differentiation (79.1% versus 20.9%, p=0.007), poor MSKCC risk score (78.4% versus 21.6%, p<0.001) and poor IMDC risk score (74.4% versus 25.6%, p<0.001) than ROD<1.34 group.Conclusion: Primary tumor with higher ROD was an independently prognostic factor for both PFS and OS in patients with mccRCC who received targeted therapy. Higher ROD was also associated with high T stage, high WHO/ISUP grade, sarcomatoid features, tumor necrosis, poor MSKCC and IMDC risk score.

654 Background: We investigated correlation of their pathological findings and their prognostic factors in non-clear cell renal cell carcinoma (ncRCC) diagnosed by both regional pathology (RP) and central pathology (CP) in multicenter study. Methods: In January 2005 to December 2014, 140 cases of ncRCC diagnosed by radical or partial nephrectomy were assessed. We assessed their pathological diagnosis by one central pathologist using the 2016 WHO classification tumor of the kidney. We assessed the correlation between clinical parameters or pathological findings and their prognosis. Then, we performed immunohistochemical analysis using PD-1 related antibody in ncRCC. Results: Median follow up was 32.7 months (1-134). Median age was 66 years, 99 males and 41 females. Pathological stage was pT1a: 58, pT1b: 30, pT2a: 17, pT2b: 6, pT3a: 21, pT3b: 2, pT4: 3 cases, respectively. In RP, histology was papillary (PAP): 60 (42.9%), chromophobe (CHR): 49 (35.0%), containing with sarcomatoid components (SAR): 14 (10.0%) and other histology: 17 (12.1%) cases, respectively. The tumors evaluable by CP were 127 cases, PAP: 52 (40.9%), CHR: 31 (24.4%), SAR: 20 (15.7%) and other histology: 24 cases (18.8%), respectively. The overall concordance rate was 59.5% between RP and CP. In multivariate analysis, SAR was extremely poor prognosis in ncRCC. The high neutrophil lymphocyte ratio (NLR) and at high CRP value were also poor prognostic factors. So, we stratified three risk groups using three factors, namely NLR, CRP and SAR. In overall survival, there were significant prognostic differences within three groups (p = 0.0014). In immunohistochemistry, PD-1 or PD-L1 expression correlated with poor overall, cancer specific and recurrence free survival in ncRCC. In multivariate analysis, PD-L1 expression was most significant prognostic factor for ncRCC. Conclusions: These results suggest that Risk stratification by three risk factors is useful prognostic model and the expression of PD-1 and PD-L1 may be a useful prognostic factor in ncRCC.
