Purpose. This study is aimed at evaluating the clinicopathological features and prognostic significance of gastric outlet obstruction (GOO) in patients with distal gastric cancer. Methods. A retrospective review of 1564 individuals with distal gastric cancer from 2002 to 2010 was performed. In total, 157 patients had GOO. The clinicopathological features of the patients with GOO were compared with those of the patients without GOO. A Kaplan-Meier survival analysis and Cox proportional hazard model were used to assess the overall survival. Results. The patients with distal gastric cancer with GOO generally presented more aggressive pathologic features, a poorer nutritional status, more duodenal infiltration, and peritoneal dissemination than those with cancer without GOO. In the univariate analysis, curability, GOO, age, prealbumin, albumin, hemoglobin (Hb), the tumor size, the macroscopic type, lymph node metastasis, and the depth of invasion had a statistically significant influence on prognosis. The multivariate analysis showed that curability, GOO, the tumor size, lymph node metastasis, and the depth of invasion were independent prognostic factors. Conclusions. Gastric cancer with GOO exhibits aggressive biological features and has poor outcomes. The multivariate analysis showed that curability, GOO, the tumor size, lymph node metastasis, and the depth of invasion were independent prognostic factors. The gastric outlet status should be considered in the selection of surgical treatment methods for patients with gastric cancer.

Abstract Background Certain gastric cancers exhibit some primitive phenotypes, which may indicate a high malignancy. In histologically differentiated early gastric cancer (EGC), the presence and the clinicopathological significance of the primitive phenotype remain unclear. Methods Using immunohistochemical staining we detected the expression of three primitive phenotypic markers SALL4, Glypican-3(GPC3), and AFP in whole tissue sections of differentiated EGC (gastrectomy specimens, n = 302). For those cases with primitive phenotypes, we analyzed their clinicopathological features and evaluated whether the criteria for endoscopic resection were met. Results We found that 9.3% (28/302) of all differentiated EGC cases have primitive phenotypes, and most of these cases (25/28) exhibit a histomorphology similar to conventional differentiated EGC. Patients with primitive phenotypes had a deeper invasion, a higher rate of ulcer and lymphatic invasion than cases without primitive phenotype. Moreover, patients with primitive phenotypes displayed a significantly higher frequency of LNM than those without (57.1% vs 8.8%, P < 0.001). Multivariate analysis revealed that presence of primitive phenotypes was an independent risk factor for LNM (P = 0.001, HR 6.977, 95% CI: 2.199–22.138). Interestingly, we found 2 cases with primitive phenotypes developed LNM, and they both met the expanded indications of endoscopic resection for differentiated EGC. Conclusions A small number of differentiated EGC have primitive phenotypes, which were closely related to LNM and were an independent risk factor for LNM. Given its highly aggressive behavior, differentiated EGC with primitive phenotypes should be evaluated with stricter criteria before endoscopic resection, or considered to give an additional surgical operation after endoscopic resection.

Abstract Background Recent studies have shown that mixed predominantly differentiated-type (MD) early gastric cancer (EGC) might have more malignant potential than pure differentiated-type (PD) EGC. However, no study has analyzed all differentiated-type EGC cases treated endoscopically and surgically. This study aimed to compare the differences in clinicopathological features and long-term prognosis between MD- and PD-EGC. Methods We evaluated all patients with differentiated-type EGCs who were treated endoscopically and surgically in our hospital between January 2010 and October 2014. The clinicopathological features and long-term prognosis of MD-EGC were compared with those of PD-EGC. Results A total of 459 patients with 459 lesions were evaluated in this study; of them, 409 (89.1%) and 50 (10.9%) were classified into the PD and MD groups, respectively. Submucosal invasion was found in 96 (23.5%) patients of the PD group and in 33 (66.0%) patients of the MD group (p < 0.01). The rates of positive lymphatic and vascular invasion and ulceration were significantly higher in the MD group than in the PD group (p < 0.01). The proportion of patients with lymph node metastasis was also significantly higher in the MD group than in the PD group (5 (10%) vs 6 (1.5%), p < 0.01). The 5-year overall and EGC-specific survival rates in the PD group were 88.3 and 99.5%, respectively, while they were 94.0 and 98.0% in the MD group, respectively. Conclusions MD-EGC has more malignant potential than PD-EGC. However, the long-term prognosis of MD-EGC is good and is not significantly different from that of PD-EGC when treated appropriately.

Background: In patients with outlet obstruction syndrome and/or severe anemia secondary to unresectable gastric cancer (GC), partial stomach-partitioning gastrojejunostomy, or modified Devine exclusion, is a surgical alternative. Methods: A retrospective study was conducted on patients with unresectable distal GC treated with modified Devine exclusion as palliative surgery between February 2005 and December 2015. It consisted of a series of 10 patients with outlet obstruction syndrome and/or severe anemia. The outcomes of this technique were based on oral tolerance, blood transfusions, postoperative complications, and survival. Results: Early oral tolerance and a low rate of blood transfusions were observed postoperatively. There was no postoperative mortality and a very low complication rate without anastomotic leakage. Median survival was 9 months. Conclusions: Partial stomach-partitioning gastrojejunostomy is a safe procedure for unresectable GC which can improve the quality of life of these patients.

ABSTRACT EFFICACY USING THREE - DIMENSIONAL LAPAROSCOPY IN THE TREATMENT OF DISTAL GASTRIC CANCER Background: Recent studies have supported that three - dimensional (3D) laparoscopy has advantages in treating gastric cancer compared with conventional two - dimensional (2D) screens. This study investigated the safety, short - term efficacy, and oncological outcome of three - dimensional (3D) laparoscopic distal gastric cancer surgery. Materials and Methods: We prospectively analyzed the clinical data from 37 patients treated with 3D laparoscopic systemic lymphadenectomy for distal gastric cancer at the Hue Central Hospital from March 2018 to September 2021. The effects on operative time, intraoperative blood loss, the number of lymph nodes removed, postoperative recovery time, complications, and oncologic outcome were analyzed. Results: Three - dimensional (3D) laparoscopic distal gastrectomy was successfully carried out in 37 patients. The mean operative time was 69,86 ± 20,46 minutes, mean intraoperative blood loss was 171,22 ± 15,47 ml, the number of harvested lymph nodes was 20,49 ± 4,11, and the mean postoperative hospital stay was 10 (6 - 26 days). The incidence of postoperative complications was 8,1%, with 1 case of duodenal stump fistula. The one - year overall survival rate was 87,27%, and the three - year overall survival rate was 83,31%. Conclusions: 3D laparoscopy distal gastrectomy could be performed safely and feasibly. They reducethe operative time and intraoperative blood loss in distal gastrectomy with a good oncologic outcome.
