ABSTRACT
BACKGROUND:
The clinical importance of positive peritoneal cytology results in patients with pancreatic ductal adenocarcinomas remains controversial. We evaluated the prognosis of these patients and the predictive preoperative risk factors for positive peritoneal cytology results.METHODS:
We retrospectively reviewed patients who underwent curative-intent surgery at our institution between May 2010 and June 2020. Preoperative risk factors for positive peritoneal cytology results were identified using logistic regression analysis. A scoring model was constructed using the total number of significant independent predictors for positive peritoneal cytology results.RESULTS:
Of 233 patients, 18 (7.7%) had positive peritoneal cytology results. The recurrence-free survival and cancer-specific survival were markedly worse in patients with positive peritoneal cytology results than in those with negative peritoneal cytology results (recurrence-free survival 6.0 months vs. 16.6 months, p = 0.050; cancer-specific survival 19.4 months vs. 47.5 months, p = 0.034). Tumor location (odds ratio 3.760, 95% confidence interval 1.099-11.818, p = 0.023), tumor size > 25 mm (odds ratio 3.410, 95% confidence interval 1.031-11.277, p = 0.046), preoperative serosal invasion (odds ratio 5.193, 95% confidence interval 1.099-24.531, p = 0.038), and preoperative carcinoembryonic antigen level > 5.6 ng/mL (odds ratio 3.816, 95% confidence interval 1.248-10.667, p = 0.019) were identified as significant independent predictive factors. Our predictive model's optimal cutoff and positive predictive values for positive peritoneal cytology results were 3 and 27.9%, respectively.CONCLUSIONS:
The indications for curative-intent surgery should be considered carefully in patients with high-risk factors for positive peritoneal cytology results.Palavras-chave
