177 Background: Positive peritoneal cytology (PPC) in the setting of pancreatic cancer predicts a poor prognosis, such that it is considered metastatic disease in the American Joint Commission on Cancer staging guidelines. We re-evaluate the role of PPC, with particular attention to outcomes following neoadjuvant therapy. Methods: We retrospectively identified 185 patients from January 1, 2000 to present with the diagnosis of pancreatic adenocarcinoma who had undergone peritoneal washings with cytology at the time of planned resection. Data regarding demographics, tumor stage, intraoperative cytology, surgical and chemoradiation therapeutics, and clinicopathological outcomes were analyzed, with the primary endpoints being disease-free and overall survival (DFS and OS). Results: 20 patients (11%) had PPC at the time of planned resection; of these, 11 patients (55%) received neoadjuvant therapy prior to surgery. 165 patients (89%) had negative peritoneal cytology (NPC) at the time of planned resection; of these, 75 (45%) received neoadjuvant therapy prior to surgery. All patients proceeded with resection in the absence of visible metastatic disease. 42% of NPC reached 2-year survival compared to just 20% of patients with PPC. Overall, patients with PPC vs. NPC had significantly poorer DFS (p<0.0064) and OS (p<0.0135). When stratifying by neoadjuvant therapy, in those patients with stage II disease or higher who did not receive neoadjuvant therapy, multivariable CART analysis revealed that PPC predicted poorer DFS compared with NPC (p<0.004). However, among stage II or higher disease receiving neoadjuvant therapy, it failed to show a significant difference in DFS or OS between PPC and NPC. Conclusions: Overall, patients with positive peritoneal cytology are shown to have worse DFS and OS compared to patients with negative peritoneal cytology in pancreatic adenocarcinoma. However, after multivariable analysis, the prognostic significance of positive peritoneal cytology disappears in those patients with stage II and higher disease receiving neoadjuvant therapy.

Abstract Background Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the standard of care in advanced pancreatic cancer. In resectable disease, preoperative EUS-FNA can help to identify benign etiology and other cancers while preventing unnecessary surgery. However, concerns regarding tumor seeding and pancreatitis have led some experts to advocate for upfront surgery without tissue sampling. Aims To conduct a systematic review and meta-analysis of the risks and benefits of performing pre-operative EUS-FNA in patients with suspected, resectable pancreatic cancer. Methods A literature search was performed up to April 2019 using MEDLINE, EMBASE, and ISI Web of Knowledge databases with terms specified for pancreatic neoplasm and FNA. All fully published adult studies that compared preoperative EUS-FNA to EUS without FNA in resectable pancreatic cancer for short- and long-term outcomes were included. Results were reported as Odds ratios (OR) or weighted mean differences (WMD) with 95% confidence intervals (CI) using a random effects model. Heterogeneity, publication bias and quality of studies were evaluated. Sensitivity analyses were performed. The primary outcome is overall survival. Secondary outcomes include cancer free survival, tumor recurrence and seeding, and post FNA adverse events. Results An initial search yielded 2814 citations. Six retrospective studies were included with 1155 patients in the EUS-FNA group vs 2067 patients in the comparator group. Overall survival was reported in three studies (n=2701: 796 EUS-FNA, 1905 non-FNA). Patients with preoperative EUS-FNA had better overall survival compared to the non-FNA group (WMD, 4.40 months [0.02 to 8.78]). In adenocarcinoma patients (2 studies, n=2050), there was no significant difference in overall survival (WMD, 2.94 months [-3.87 to 9.74]). Cancer-free survival did not differ significantly between the two groups (WMD, 2.08 months [-2.22 to 6.38]). Moreover, EUS with FNA was not associated with increased rates of tumor recurrence (OR, 0.55 [0.30–1.02]) or peritoneal carcinomatosis (OR, 0.81 [0.56–1.18]). Post-FNA pancreatitis was rare (1.7%), with all patients treated conservatively. Sensitivity analyses yielded similar findings across the different outcomes tested. Conclusions In this meta-analysis, preoperative EUS-FNA in resectable pancreatic cancer was associated with significantly greater overall survival when compared to the non-FNA group with no significant difference in rate of tumour recurrence and/or peritoneal seeding. These findings are limited by the retrospective nature of the included studies; randomized controlled trials are needed to confirm these results. Funding Agencies None

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.

Abstract Background The added value of radiotherapy following neoadjuvant FOLFIRINOX chemotherapy in patients with resectable or borderline resectable pancreatic cancer ((B)RPC) is unclear. The objective of this meta-analysis was to compare outcomes of patients who received neoadjuvant FOLFIRINOX alone or combined with radiotherapy. Methods A systematic literature search was performed in Embase, Medline (ovidSP), Web of Science, Scopus, Cochrane, and Google Scholar. The primary endpoint was pooled median overall survival (OS). Secondary endpoints included resection rate, R0 resection rate, and other pathologic outcomes. Results We included 512 patients with (B)RPC from 15 studies, of which 7 were prospective nonrandomized studies. In total, 351 patients (68.6%) were treated with FOLFIRINOX alone (8 studies) and 161 patients (31.4%) were treated with FOLFIRINOX and radiotherapy (7 studies). The pooled estimated median OS was 21.6 months (range 18.4–34.0 months) for FOLFIRINOX alone and 22.4 months (range 11.0–37.7 months) for FOLFIRINOX with radiotherapy. The pooled resection rate was similar (71.9% vs. 63.1%, p = 0.43) and the pooled R0 resection rate was higher for FOLFIRINOX with radiotherapy (88.0% vs. 97.6%, p = 0.045). Other pathological outcomes (ypN0, pathologic complete response, perineural invasion) were comparable. Conclusions In this meta-analysis, radiotherapy following neoadjuvant FOLFIRINOX was associated with an improved R0 resection rate as compared with neoadjuvant FOLFIRINOX alone, but a difference in survival could not be demonstrated. Randomized trials are needed to determine the added value of radiotherapy following neoadjuvant FOLFIRINOX in patients with (B)PRC.

The systemic inflammation plays a crucial role in carcinogenesis and cancer progression. Pretreatment lymphocyte-to-monocyte ratio (LMR) has been suggested to be associated with clinical outcomes in various malignancies. To evaluate the prognostic significance of pretreatment LMR on gastric cancer, we conducted a comprehensive literature search in PubMed, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov (Prospero Registration No. CRD42018087263). This meta-analysis included all studies evaluating the prognostic significance of pretreatment LMR on gastric cancer. The main outcome measures included overall survival (OS), progression-free survival (PFS), and the relationship between LMR and clinicopathological features. In total, 11 studies (12 cohorts) enrolling 14,262 patients with gastric cancer were included. The pooled estimates showed that elevated pretreatment LMR was significantly associated with better OS (hazard ratio (HR): 0.71, 95% confidence interval (CI): 0.58–0.83) and better PFS (HR: 0.71, 95% CI: 0.44–0.99). The elevated LMR was also significantly associated with young patients, female, low level of carcinoembryonic antigen (CEA), low level of carbohydrate antigen 19-9 (CA19-9), stage I–II, small tumor size, absence of lymph node metastasis, absence of vascular invasion, and absence of perineural invasion. In conclusion, the elevated pretreatment LMR predicted the better clinical outcomes in patients with gastric cancer.

Abstract The effectiveness of neoadjuvant therapy (NAT) remains unclear in resectable pancreatic cancer (PC) as compared with upfront surgery (US). The aim of this study was to investigate the survival gain of NAT over US in resectable PC. PubMed and EMBASE were searched for studies comparing survival outcomes between NAT and US for resectable PC until June 2018. Overall survival (OS) was analyzed according to treatment strategy (NAT versus US) and analytic methods (intention-to-treat analysis (ITT) and per-protocol analysis (PP)). In 14 studies, 2,699 and 6,992 patients were treated with NAT and US, respectively. Although PP analysis showed the survival gain of NAT (HR 0.72, 95% CI 0.68–0.76), ITT analysis did not show the statistical significance (HR 0.96, 95% CI 0.82–1.12). However, NAT completed with subsequent surgery showed better survival over US completed with adjuvant therapy (HR 0.82, 95% CI 0.71–0.93). In conclusion, the supporting evidence for NAT in resectable PC was insufficient because the benefit was not demonstrated in ITT analysis. However, among the patients who completed both surgery and chemotherapy, NAT showed survival benefit over adjuvant therapy. Therefore, NAT could have a role of triaging the patients for surgery even in resectable PC.
