AIMTo identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors.METHODSThree-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy (distal gastrectomy or total gastrectomy) were included in the analysis. Correlations between 21 parameters that can be determined by preoperative routine blood tests and clinically relevant postoperative complications (grade II or higher according to the Clavien-Dindo classification) were evaluated. The optimal cutoff values and clinical significance of the selected markers were further evaluated by subgroup analyses according to age, body mass index, operative procedure and clinical disease stage.RESULTSSixty-six patients (21.1%) experienced grade II or higher postoperative complications. The platelet-lymphocyte ratio (PLR, total lymphocyte count/platelet count × 100) exhibited the highest area under the curve value (0.639) for predicting postoperative complications among the 21 parameters, and the optimal cutoff value was determined to be 0.71 (sensitivity = 70%, specificity = 56%). In the univariate analysis, the odds ratio of a low PLR for the occurrence of postoperative complications was 2.94 (95%CI: 1.66-5.35, P < 0.001), and a multivariate binomial logistic analysis involving other potential risk factors identified a low PLR as an independent risk factor for postoperative complications (OR = 3.32, 95%CI: 1.82-6.25, P < 0.001). In subgroups classified according to age, body mass index, operative procedure and clinical disease stage, the low PLR group exhibited an increased incidence of postoperative complications.CONCLUSIONThe preoperative PLR is a simple and useful predictor of complications after curative gastrectomy in patients with clinical T2-4 gastric cancer.
ALBI grade serves as a simple and promising predictive factor for disease-free and disease-specific survival in patients with pT2-4 GC after radical gastrectomy.
Background/Aims: Do serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 levels serve as prognostic indicators in patients with gastric cancer (GC)? This is a question that has long been disputed. The aim of this study was to evaluate the significance of perioperative serum levels of CEA and CA19-9 for predicting the recurrence and long-term survival after patients with pT2-4 GC undergo curative gastrectomy. Methods: This study included 251 patients with radically resected pT2-4 GC without preoperative treatment. Associations between the preoperative and postoperative serum levels of CEA or CA19-9 and postoperative long-term outcomes and recurrence patterns were evaluated. Results: Preoperative CEA >5.0 ng/mL was an independent prognostic factor of overall survival. Elevation of both preoperative CEA and CA19-9 levels showed no synergistic adverse effects on prognosis. Preoperative levels of these markers achieved superior predictive performance compared with the postoperative values. Adverse prognosis is significantly associated with persistent elevation of CEA levels before and after gastrectomy. Elevation of CEA levels, particularly at postoperative measurement, was significantly associated with hematogenous recurrence. Conclusion: Determination of perioperative CEA levels facilitated predictions of recurrence patterns and prognosis among patients with pT2-4 GC who underwent curative gastrectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
