CRP and neoplasm: In contrast, the current analysis not only showed that stratification of postresection survival of pNEN is similar for grading as a postresection risk factor and serum CRP as a preoperative risk factor (shown in Fig. 1), but also confirms preoperative serum CRP as an independent preoperative risk factor associated with overall survival in multivariable analysis independent from grading and advanced tumour stages (Tables 3 and 4).
