Abstract Background: Few studies have suggested the correlation between intraoperative dexamethasone and oncological outcomes in non-small cell lung cancer (NSCLC) patients with radical resection. The existing data are inconsistent and inadequate, and more evidence is needed. We therefore undertook a propensity-matched cohort study to investigate the correlation. Methods: 832 patients with stage I to IIIa NSCLC who went through a curative resection between January 2008 and December 2013 were enrolled in our study. Propensity-score matching analysis created a population of 206 patients in the non-DEX group and 103 patients in the DEX group. Cox regression analyses were applied to compare the disease-free survival (DFS) and overall survival (OS) between patients who did not and did receive dexamethasone in the propensity score-matched cohort, as well as in the certain patients with high-risk factors of postoperative nausea and vomiting. Results: After propensity score matching, intraoperative dexamethasone was not significantly associated with DFS (HR: 1.014, 95%CI: 0.786-1.309, P = 0.913) and OS (HR: 1.221, 95%CI: 0.905-1.647, P = 0.191). Multivariable cox regression analysis revealed that intraoperative dexamethasone was not still associated with DFS and OS after curative resection for NSCLC. In the subgroup analysis, intraoperative dexamethasone was significantly associated with improved DFS (HR: 0.20, 95%CI: 0.04-0.92, P = 0.038) in the group of anesthetic time less than 2 hours. In the subgroup of VATS, intraoperative dexamethasone was significantly associated with prolonged OS (HR: 0.53, 95%CI: 0.30-0.92, P = 0.023). Conclusion: There was no correlation between intraoperative administration of dexamethasone and survival in NSCLC patients after curative surgery. While patients given intraoperative dexamethasone had better disease-free survival compared with patients not given intraoperative dexamethasone in the subgroup of anesthetic time less than 2 hours. Intraoperative administration of dexamethasone may improve overall survival in the subgroup of VATS. Our results indicate that intraoperative administration of dexamethasone is probably favorable in the aforementioned populations.

Abstract Objective There are limited data from retrospective studies on whether therapeutic outcomes after regular pancreatectomy are superior to those after enucleation in patients with small, peripheral and well-differentiated non-functional pancreatic neuroendocrine tumors. This study aimed to compare the short- and long-term outcomes of regular pancreatectomy and enucleation in patients with non-functional pancreatic neuroendocrine tumors. Methods Between January 2007 and July 2020, 227 patients with non-functional pancreatic neuroendocrine tumors who underwent either enucleation (n = 89) or regular pancreatectomy (n = 138) were included. Perioperative complications, disease-free survival, and overall survival probabilities were compared. Propensity score matching was performed to balance the baseline differences between the two groups. Results The median follow-up period was 60.76 months in the enucleation group and 43.29 months in the regular pancreatectomy group. In total, 34 paired patients were identified after propensity score matching. The average operative duration in the enucleation group was significantly shorter than that in the regular pancreatectomy group (147.94 ± 42.39 min versus 217.94 ± 74.60 min, P < 0.001), and the estimated blood loss was also significantly lesser (P < 0.001). The matched patients who underwent enucleation displayed a similar overall incidence of postoperative complications (P = 0.765), and a comparable length of hospital stay (11.12 ± 3.90 days versus 9.94 ± 2.62 days, P = 0.084) compared with those who underwent regular pancreatectomy. There were no statistically significant differences between the two groups in disease-free survival and overall survival after propensity score matching. Conclusion Enucleation in patients with non-functional pancreatic neuroendocrine tumors was associated with shorter operative time, lesser intraoperative bleeding, similar overall morbidity of postoperative complications, and comparable 5-year disease-free survival and overall survival when compared with regular pancreatectomy.

Abstract Background Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an infrequent type of primary liver cancer that comprises hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). This study investigated the clinicopathological features and prognosis among cHCC-CC, HCC, and CC groups. Methods We prospectively collected the data of 608 patients who underwent surgical resection for liver cancer between 2011 and 2018 at E-Da Hospital, I-Shou University, Kaohsiung, Taiwan. Overall, 505 patients with cHCC-CC, HCC, and CC were included, and their clinicopathological features, overall survival (OS), and recurrence were recorded. OS and recurrence rates were analyzed using the Kaplan–Meier analysis. Results In the entire cohort, the median age was 61 years and 80% were men. Thirty-five (7.0%) had cHCC-CC, 419 (82.9%) had HCC, and 51 (10.1%) had CC. The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. OS was significantly lower in the cHCC-CC group than in the HCC group but was not significantly higher in the cHCC-CC group than in the CC group. The median OS of cHCC-CC, HCC, and CC groups was 50.1 months [95% confidence interval (CI): 38.7–61.2], 62.3 months (CI: 42.1–72.9), and 36.2 months (CI: 15.4–56.5), respectively. Cumulative OS rates at 1, 3, and 5 years in cHCC-CC, HCC, and CC groups were 88.5%, 62.2%, and 44.0%; 91.2%, 76.1%, and 68.0%; and 72.0%, 48.1%, and 34.5%, respectively. After propensity score matching (PSM), OS in the cHCC-CC group was not significantly different from that in the HCC or CC group. However, OS was significantly higher in the HCC group than in the CC group before and after PSM. Furthermore, the disease-free survival was not significantly different among cHCC-CC, HCC, and CC groups before and after PSM. Conclusion The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. The OS rate was significantly lower in the cHCC-CC group than the HCC group. However, after PSM, OS and disease-free survival in the cHCC-CC group were not significantly different from those in the HCC or CC group.

Abstract Background: The neutrophil-to-lymphocyte ratio is a significant prognostic marker in resectable colorectal cancer; however, there are no equivalent findings for perforated colon cancer. Using our colorectal cancer database, we retrospectively analyzed the data from 1995 to 2015 to determine whether the preoperative neutrophil-to-lymphocyte ratio is associated with survival outcomes in patients with perforated colon cancer.Methods: One-to-one propensity score matching was applied to minimize the difference between the high (>5) and low (≤5) neutrophil-to-lymphocyte ratio groups. Clinicopathological factors, long-term overall survival, and disease-free survival were analyzed and compared between the two groups. The primary outcomes were overall survival and disease-free survival.Results: Before propensity score matching, the high neutrophil-to-lymphocyte ratio group had a significantly higher prevalence of leukocytosis (low vs. high neutrophil-to-lymphocyte ratio groups: 12 [12.9%] vs. 46 [59.7%], p<0.001), lower serum albumin levels (low vs. high neutrophil-to-lymphocyte ratio groups: 30 [32.3%] vs. 42 [54.5%], p=0.003), and a higher emergent operation rate (low vs. high neutrophil-to-lymphocyte ratio groups: 5 [5.4%] vs. 20 [26.0%], p<0.001). After one-to-one propensity score matching, the groups comprised 41 patients each; none of the parameters were significantly different between the two groups. The mean follow-up period was 76.3 months. The 5-year overall survival (p=0.637) and disease-free survival (p=0.827) rates were not significantly different between the high and low neutrophil-to-lymphocyte ratio groups.Conclusions: The neutrophil-to-lymphocyte ratio has limited predictive value for determining outcomes in patients with perforated colon cancer.

Objective To compare the surgical effects and long-term efficacy of hand-assisted laparoscopic surgery (HALS) and open surgery (OS) in radical gastrectomy for advanced distal gastric cancer. Methods One hundred twenty-four patients who were admitted to the Department of Gastrointestinal Surgery of the West War Zone General Hospital from May 2008 to April 2012 were randomly divided into a HALS group (n = 62) and an OS group (n = 62). After surgery, 113 patients were followed up for 5 and 8 years, and 11 patients were lost to follow-up. The 5- and 8-year overall survival and disease-free survival rates of the two groups were compared and analyzed. Results The 5- and 8-year overall survival rates were 31.90% and 18.40% in the HALS group and 32.50% and 18.60% in the OS group, respectively. The 5- and 8-year disease-free survival rates were 21.50% and 13.00% in the HALS group and 21.90% and 13.10% in the OS group, respectively. No significant differences were found. Conclusion Hand-assisted laparoscopic radical gastrectomy for advanced distal gastric cancer has the advantages of less severe trauma, less intraoperative blood loss, more rapid postoperative recovery, and equivalent long-term efficacy compared with OS.
