BACKGROUND: Systematic lymphadenectomy for the resection of sufficient lymph nodes is the most important part of curative resection in gastric cancer surgery. Here, we explore the outcomes of the three-step method for modular lymphadenectomy (TSMML) and determine its safety and efficacy, compared with the conventional method for lymphadenectomy (CML). METHODS: From 2008 to 2011, 270 patients with gastric cancer were divided into 2 subgroups: the TSMML group and the CML group...

OBJECTIVE: The aim of the study was to compare the clinical symptoms between Billroth II (B-II) and Roux-en-Y (R-Y) reconstruction after distal subtotal gastrectomy (DG) for gastric cancer. BACKGROUND: Surgery is the mainstay of curative treatment for gastric cancer. The technique for reconstruction after DG remains controversial. Both B-II and R-Y are popular methods. METHODS: This is a prospective multicenter randomized controlled trial...

BACKGROUND: Laparoscopic 180° anterior fundoplication has been shown to achieve similar reflux control to Nissen fundoplication, with fewer side-effects, up to 5 years. However, there is a paucity of long-term follow-up data on this technique and antireflux surgery in general. This study reports 12-year outcomes of a double-blind RCT comparing laparoscopic Nissen versus 180° laparoscopic anterior fundoplication for gastro-oesophageal reflux disease (GORD). METHODS: Patients with proven GORD were randomized to laparoscopic Nissen or 180° anterior fundoplication...

OBJECTIVE: Laparoscopic sleeve gastrectomy (LSG) is performed almost as often in Europe as laparoscopic Roux-Y-Gastric Bypass (LRYGB). We present the 3-year interim results of the 5-year prospective, randomized trial comparing the 2 procedures (Swiss Multicentre Bypass Or Sleeve Study; SM-BOSS). METHODS: Initially, 217 patients (LSG, n = 107; LRYGB, n = 110) were randomized to receive either LSG or LRYGB at 4 bariatric centers in Switzerland. Mean body mass index of all patients was 44 ± 11 kg/m, mean age was 43 ± 5...

BACKGROUND: Feeding jejunostomy tubes (FJT) in patients undergoing resection of gastroesophageal cancers facilitate perioperative nutrition. Data regarding FJT use and complications are limited. STUDY DESIGN: A single institution review was performed for patients who underwent perioperative FJT placement for gastrectomy or esophagogastrectomy from 2007 to 2015. FJT-related and unrelated complications were evaluated. RESULTS: FJTs were inserted for total/completion gastrectomy (n = 49/117, 41...

Surgical resection is the primary method of obtaining a potential cure for patients with gastric adenocarcinoma. However, chemotherapy or chemoradiotherapy offer significant improvement in survival over surgery alone. Much of the difficulty in deciding the optimal treatment strategy is choosing between perioperative chemotherapy or adjuvant chemoradiotherapy. Adding to the complexity is the potential for incorporating treatment strategies based on clinical trials performed in Asia. There is likely a difference in tumor biology between Eastern and Western patients with gastric adenocarcinoma, in addition to the clear differences in screening, pathologic assessment, and surgical technique...

BACKGROUND: Randomized trials have shown that neoadjuvant treatment improves survival in the curative treatment of oesophageal and gastro-oesophageal junction cancer. Results from population-based observational studies are, however, sparse and ambiguous. METHODS: This prospective population-based cohort study included all patients who had oesophagectomy for cancer in Sweden, excluding clinical T1 N0, recorded in the National Register for Oesophageal and Gastric Cancer, 2006-2014...

OBJECTIVE: The aim of this study is to investigate the impact of the circumferential resection margin (CRM) in esophageal cancer on survival and recurrence in patients without pretreatment. BACKGROUND: Whereas the infiltration of the proximal or distal resection margin is associated with poor survival and higher recurrence, studies looking at the role of the circumferential resection margin on survival and local recurrence after esophagectomy are conflicting. METHODS: Influence of CRM infiltration according to the College of American Pathologists (CAP) and Royal College of Pathologists (RCP) on long-term survival of 180 patients with resected pT3 tumors and without neoadjuvant therapy was analyzed...

INTRODUCTION: Patients undergoing non-elective paraesophageal hernia repair (PEHR) have worse perioperative outcomes. Because they are usually older and sicker, however, these patients may be more prone to adverse events, independent of surgical urgency. Our study aimed to determine whether non-elective PEHR is associated with differential postoperative outcome compared to elective repair, using propensity-score weighting. METHODS: We abstracted data for patients undergoing PEHR (n = 924; non-elective n = 171 (19 %); 1997-2010)...

BACKGROUND: Platelet and blood coagulation abnormalities frequently occur in cancer patients. Fibrinogen is an important hemostatic factor that regulates the hemostatic pathway. Hyperfibrinogenemia is increasing recognized as an important risk factor influencing cancer development and outcome. However, few reports have investigated the prognostic potential of fibrinogen for predicting the survival of gastric cancer (GC) patients. The primary aim of this study was to evaluate the usefulness of preoperative serum fibrinogen as a biomarker for predicating tumor progression and survival of patients with GC...

BACKGROUND: Because postoperative convalescence often prolongs the interval between surgery and chemotherapy in patients undergoing treatment for advanced gastric cancer, this study assesses the survival impact of timing of adjuvant chemotherapy (AC) in patients undergoing curative resection for gastric cancer. METHODS: The 2003-2012 ACS NCDB was analyzed for patients treated with gastrectomy for stages 1-3 gastric cancer. Treatment groups were stratified by time to initiation of AC: initiation of chemotherapy within 8 weeks postoperatively, between 8 and 12 weeks postoperatively, after 12 weeks postoperatively, and no chemotherapy...

BACKGROUND: There is debate surrounding the use of laparoscopic resection for advanced gastric cancer in the Western population. Here we aim to assess the feasibility and short-term outcomes of laparoscopic gastrectomy in consecutive patients in a Western population. METHODS: From 2012 to 2014, retrospective review of 28 patients with clinically staged advanced gastric cancer (≥T3 or ≥N1) treated with laparoscopic resection. RESULTS: Sixty-one percentage of patients were male...

AIM: The aim of this study was to determine the oncologic value of omentectomy in patients undergoing gastrectomy for gastric cancer. METHODS: All consecutive patients with gastric cancer that underwent gastrectomy with curative intent between April 2012 and August 2015 were prospectively analyzed. The greater omentum was separately marked during operation and pathologically evaluated for the presence of omental lymph nodes and tumor deposits. RESULTS: In total, 50 patients were included...

BACKGROUND: The hypermethylation of ring finger protein (RNF) 180 DNA promoter is significantly associated with lymph node metastasis of gastric cancer. The present study explored the potential mechanism of RNF180-regulated lymph node metastasis of gastric cancer. METHODS: Associations between clinicopathological and survival data and RNF180 expression in gastric cancer tissues were analysed. The effects of RNF180 re-expression on gastric cancer cells were determined by means of proliferation, invasion, growth and lymphangiogenesis assays...

BACKGROUND: Several small studies indicated that the genotype of KIT or platelet-derived growth factor receptor-α (PDGFRA) contributes in part to the level of clinical effectiveness of sunitinib in gastrointestinal stromal tumor (GIST) patients. This study aimed to correlate KIT and PDGFRA mutational status with clinical outcome metrics (progression-free survival [PFS], overall survival [OS], objective response rate [ORR]) in a larger international patient population. METHODS: This is a non-interventional, retrospective analysis in patients with imatinib-resistant or intolerant GIST who were treated in a worldwide, open-label treatment-use study (Study 1036; NCT00094029) in which sunitinib was administered at a starting dose of 50 mg/day on a 4-week-on, 2-week-off schedule...

BACKGROUND: The benefit of adjuvant therapy following resection of early stage, node-negative gastric adenocarcinoma following a margin negative (R0) resection is unclear. METHODS: The National Cancer Data Base was used to identify patients with a T2N0 gastric adenocarcinoma (tumor invasion into the muscularis propria) who underwent R0 resection. Patients treated with neoadjuvant therapy and those for whom lymph node count was unavailable were excluded from the analysis...

BACKGROUND: Resectable gastroesophageal junction (GEJ) tumors are treated either with an esophageal-cardia resection or with gastrectomy. The difference in outcome between these two treatment modalities is unknown; Therefore, the aim of this study was to evaluate population-based treatment strategies for patients with resectable adenocarcinomas of the GEJ and to compare the oncological outcomes. METHODS: Patients with potentially resectable GEJ tumors diagnosed between 2005 and 2012 were selected from the nationwide, population-based Netherlands Cancer Registry...

BACKGROUND: Late recurrence of gastric cancer is rare and there are few data on recurrence in patients who are disease free for >5 years after gastrectomy. The aim of this study was to evaluate the predictors and status of tumor recurrence among these patients. METHODS: Clinicopathologic characteristics, patterns of recurrence, and postrecurrence survival were analyzed in patients who were diagnosed as disease free at 5 years postoperatively and thereafter experienced recurrence...

BACKGROUND: Weight loss following gastrectomy for patients with gastric cancer has not been well characterized. We assessed the impact of patient and procedure-specific variables on postoperative weight loss following gastrectomy for cancer. METHODS: A prospectively maintained gastric cancer database identified patients undergoing gastrectomy for cancer. Clinical and pathologic characteristics, baseline body mass index (BMI), and postoperative weights were extracted...
