Objective::In 2015, the Chinese Pancreatic Association of the Chinese Society of Surgery of the Chinese Medical Association launched a national multicenter online system for registration of surgical treatment of pancreatic cancer in China, called China Pancreas Data Center (CPDC). With continued effort, the CPDC has developed over time. Herein, we report the general results of the CPDC from January 2016 to January 2020 to present the real-world situation of surgical treatment of pancreatic cancer in China.Methods::The data of the CPDC from January 2016 to January 2020 were retrieved and analyzed in this real-world study, including the data on patient demographics, comorbidities, diagnostic modalities, neoadjuvant treatment, surgical procedures, postoperative complications and treatment, pathological examinations, postoperative adjuvant treatment, survival, and risk factors.Results::A total of 13,595 cases from 70 centers in 28 provinces were retrieved for analysis. This study reported the largest cohort of patients who underwent surgical treatment for pancreatic cancer in China to date. More cases were derived from the Eastern regions, among which Shanghai, Beijing, and Zhejiang ranked in the top three. The peak age of the patients ranged from 60 to 69 years. The ratio of males to females was 1.5:1. Overall, 64.3% of the tumors were located in the head and neck of the pancreas, and 35.7% in the body and tail of the pancreas. Of the patients, 23.0% underwent positron-emission tomography-computed tomography, 21.6% underwent endoscopic ultrasound, and 4.8% underwent preoperative biopsy. Two percent of the patients underwent neoadjuvant treatment, while 68.9% underwent R0 surgical resection (margin free of tumor cells). Of the latter, 78.6% of the operations were open procedures, 12.6% were laparoscopic procedures, 2.9% were robotic procedures, and 3.7% were converted to open procedures. The in-hospital mortality rate after surgery was 0.4%. The incidence of grade 2 and grade 3 postoperative pancreatic fistulas was 25.5% and 2.5%, respectively. The incidence of complications based on the Clavien-Dindo classification was 17.9% of grade II, 4.3% of grade IIIa, 1% of grade IIIb, and 0.6% of grade IV. Of the patients, 28.9% underwent postoperative adjuvant chemotherapy. The 1-year, 2-year, and 3-year overall survival of these patients were 77%, 51%, and 38%, respectively. In the 8542 patients who underwent R0 resection, the 1-year, 2-year, and 3-year overall survival and disease-free survival were 77% , 54%, and 43%, and 68%, 49%, and 41%, respectively. The factors related to the prognosis of these patients were also identified after uni-and multi-variate analyses.Conclusion::The surgical quality, safety, and long-term survival of the patients in CPDC are similar to those of international high-volume pancreatic centers. However, neoadjuvant and postoperative adjuvant chemotherapy should be improved.
