Abstract

Background: Recently, real‐world data have been recognized to have a significant role for research and quality improvement worldwide. The decision on the existence or nonexistence of postoperative complications is complex in clinical practice. This multicenter validation study aimed to evaluate the accuracy of identification of patients who underwent gastrointestinal (GI) cancer surgery and extraction of postoperative complications from Japanese administrative claims data. Methods: We compared data extracted from both the Diagnosis Procedure Combination (DPC) and chart review of patients who underwent GI cancer surgery from April 2016 to March 2019. Using data of 658 patients at Kyoto University Hospital, we developed algorithms for the extraction of patients and postoperative complications requiring interventions, which included an invasive procedure, reoperation, mechanical ventilation, hemodialysis, intensive care unit management, and in‐hospital mortality. The accuracy of the algorithms was externally validated using the data of 1708 patients at two other hospitals. Results: In the overall validation set, 1694 of 1708 eligible patients were correctly extracted by DPC (sensitivity 0.992 and positive predictive value 0.992). All postoperative complications requiring interventions had a sensitivity of >0.798 and a specificity of almost 1.000. The overall sensitivity and specificity of Clavien–Dindo ≥grade IIIb complications was 1.000 and 0.995, respectively. Conclusion: Patients undergoing GI cancer surgery and postoperative complications requiring interventions can be accurately identified using the real‐world data. This multicenter external validation study may contribute to future research on hospital quality improvement or to a large‐scale comparison study among nationwide hospitals using real‐world data.

Abstract

Background/aim: Laparoscopic gastrectomy is a standard treatment strategy for gastric cancer (GC); however, the clinical impact of laparoscopic total gastrectomy (LTG) on survival outcomes remains unclear. We compared the short- and long-term results of LTG with those of open total gastrectomy (OTG)., Patients and Methods: Patients undergoing total gastrectomy with lymph node dissection for Stage I/II/III GC between 2010 and 2020 were retrospectively analyzed. Patients were classified into those undergoing LTG (n=143, LTG group) and OTG (n=173, OTG group). The primary outcome was relapse-free survival (RFS)., Results: The LTG group exhibited a higher prevalence of early T and N factors, with pStage I/II/III distribution skewed toward early-stage in a ratio of 86/24/33 compared to 38/65/69 in the OTG group (p<0.001), respectively. Longer operation time (p<0.001), less blood loss (p<0.001), fewer grade 3-4 complications (p<0.001), and shorter hospital stay (p<0.001) were observed in the LTG than in the OTG group. LTG was associated with survival benefits for patients without indication for adjuvant chemotherapy [5-year RFS rate, 96.3% vs. 73.2%; hazard ratio (HR)=0.24; 95% confidence interval (CI)=0.10-0.56; p<0.001]. Among the eligibility criteria for adjuvant chemotherapy (Stage II/III excluding pT1 and pT3N0), while the LTG group received more frequently doublet-agent administration (56.5% vs. 11%, p<0.001), conversely, the OTG group exhibited slightly better long-term survival rates (5-year RFS rate, 33.9% vs. 50.2%; HR=1.31; 95%CI=0.82-2.10; p=0.251)., Conclusion: LTG contributed to favorable short-term outcomes and demonstrated improved long-term outcomes in early-stage GC; however, careful consideration of indications is warranted for advanced GC cases., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.
