Ca gastrico

Worldwide, gastric cancer represents the fifth most common cancer and the third leading cause of cancer deaths. Although the overall 5-year survival for resectable disease was more than 70% in Japan due to the implementation of screening programs resulting in detection of disease at earlier stages, in Western countries more than two thirds of gastric cancers are usually diagnosed in advanced stages reporting a 5-year survival rate of only 25.7%. Anyway surgical resection with extended lymph node dissection remains the only curative therapy for non-metastatic advanced gastric cancer, while neoadjuvant and adjuvant chemotherapies can improve the outcomes aimed at the reduction of recurrence and extension of survival...

BACKGROUND: Laparoscopic proximal gastrectomy (LPG) has recently been applied for early gastric cancer (EGC) in the upper stomach as a minimally invasive and function-preserving surgery. This study aimed to clarify the feasibility and nutritional benefits of LPG over laparoscopic total gastrectomy (LTG). METHODS: This was a retrospective study of 77 patients with clinical stage I gastric cancer in the upper stomach. Of these patients, 25 underwent LPG, while 52 underwent LTG...

BACKGROUND: Multidetector computed tomography (MDCT) is essential for the prediction of lymph node (LN) metastasis in gastric cancer. However, the measurement method and size criteria for metastatic LNs using MDCT are unclear. METHODS: MDCTs of gastric cancer patients who underwent surgery and had pathological staging were reviewed by radiologists. The two-dimensional cutoff values for LNs with suspected metastasis were calculated, and clinicopathological data were analyzed using those cutoff values...

BACKGROUND: The effect of routine drainage after abdominal surgery with enteric anastomoses is controversial. In particular, the role of peritoneal drain (PD) placement after total gastrectomy for adenocarcinoma is not well established. METHODS: Patients who underwent total gastrectomy for gastric adenocarcinoma (GAC) at seven institutions from the US Gastric Cancer Collaborative, from 2000 to 2012, were identified. The association of PD placement with postoperative outcomes was analyzed...

BACKGROUND: Elderly patients undergoing gastrectomy are expected to be at high risk of postoperative complications. This retrospective multicenter cohort study assessed complications and long-term outcomes after gastrectomy for gastric cancer (GC). METHODS: A total of 993 patients with GC who had undergone gastrectomy were included, comprising 186 elderly patients (age ≥ 80 y, E group) and 807 nonelderly patients (age ≤ 79 y, NE group). Preoperative comorbidities, operative results, postoperative complications, and clinical outcomes were compared between the groups...

BACKGROUND: Gastrectomy remains the primary therapeutic method for resectable gastric cancer. Thought of as an important measure to reduce post-operative complications and mortality, abdominal drainage has been used widely after gastrectomy for gastric cancer in previous decades. The benefits of abdominal drainage have been questioned by researchers in recent years. OBJECTIVES: The objectives of this review were to assess the benefits and harms of routine abdominal drainage post-gastrectomy for gastric cancer...

Robotic surgery for gastric cancer overcomes technical difficulties with laparoscopic gastrectomy. Its benefits include reduced intraoperative bleeding and shorter hospital stays; it is also easier to learn. Because accuracy increases during lymphadenectomy, a larger number of lymph nodes is likely to be retrieved using robotic gastrectomy. Higher costs and longer operation times have hindered the widespread adaptation and use of robotic surgery. In this review, we summarize the current status and issues regarding robotic gastrectomy...

BACKGROUND: Lymph node positivity is a strong prognostic indicator in many cancers including gastric cancer. The extent of surgical resection directly influences the number of lymph nodes available for staging, with the lesser D1 resection that is standard practice in non-Asian countries typically providing fewer nodes for analysis. The widely used AJCC TNM staging system has been criticized for under-staging and stage migration where fewer than 15 nodes are resected, which is often the case in these populations...

BACKGROUND: Category 1 guidelines emphasize multimodality therapy (MMT) for patients with gastric cardia cancer (GCC). These patients are often referred to thoracic surgeons for "esophagogastric junction" cancers rather than to abdominal surgeons for "proximal gastric" cancers. This study sought to determine the ideal surgical approach using national datasets evaluating morbidity/mortality (M/M) and overall survival (OS). STUDY DESIGN: Patients with resected GCC were identified from the 2005 to 2012 ACS-NSQIP dataset and the 1998 to 2010 SEER dataset...

BACKGROUND: Neoadjuvant therapy is recommended for locally advanced gastric cancer patients (stage IB-IIIC). The objective of this study is to evaluate the accuracy of endoscopic ultrasound (EUS) and computed tomography (CT) in identifying patients with locally advanced gastric cancer. METHODS: Patients with gastric adenocarcinoma who underwent gastrectomy at our institution were reviewed. Preoperative EUS and CT staging were compared with pathologic staging to determine accuracy...

BACKGROUND: The purpose of this study was to determine the survival of patients with metastatic gastric cancer treated with surgery. METHODS: We reviewed the medical records of 7,404 patients with gastric or gastroesophageal cancer seen from January 1995 to August 2012 at MD Anderson Cancer Center and identified patients with stage IV disease treated with surgery. Kaplan-Meier curves were created to compare overall survival (OS) between groups. RESULTS: Of the 82 patients who met inclusion criteria, sites of metastatic disease included peritoneum (N = 34, 42%), positive cytology only (N = 17, 21%), distant lymph nodes (N = 12, 15%), and distant organs (N = 19, 23%)...

OBJECTIVE: This study aims to answer the superiority of comparing laparoscopy-assisted distal gastrectomy (LADG) with open distal gastrectomy (ODG) in the treatment early gastric cancer (EGC). MATERIAL AND METHODS: A comprehensive search up to May 31, 2014 was conducted on PubMed, Web of science, and the Cochrane Library. All eligible studies comparing LADG versus ODG were included. Data synthesis and statistical analysis were performed using RevMan 5.2 software...

BACKGROUND: A proximal margin distance of 5 cm is advocated for resection of gastric adenocarcinoma (GAC). We assessed the prognostic value of proximal margin (PM) distance on survival outcomes after resection of distal GAC. METHODS: All patients who underwent resection of distal GAC (antrum/body) from 2000 to 2012 at seven institutions of the U.S. Gastric Cancer Collaborative were included. Patients with positive distal margins or macroscopic residual disease were excluded...

INTRODUCTION: Poor results have been reported after conventional gastrojejunostomy (CGJ) as palliative surgical bypass treatment of gastric outlet obstruction (GOO). Partial stomach-partitioning gastrojejunostomy (PSPGJ) has been introduced as an alternative surgical treatment of GOO to reduce the risk of postoperative delayed gastric emptying (DGE). AIM: The aim was to study PSPGJ as an alternative to CGJ in the treatment of GOO, with respect to DGE. PATIENTS AND METHODS: A retrospective cohort study was completed in all patients who underwent a bypass of the duodenum via PSPGJ or CGJ due to GOO...

BACKGROUND: Advanced gastric cancer in the upper or middle third of the stomach is routinely treated with a total gastrectomy, albeit in some cases with higher morbidity and mortality. The aim of this study was to describe the morbimortality and survival results in total gastrectomy in a single center. METHODS: This retrospective study included patients with gastric adenocarcinoma treated with a total gastrectomy at a single Brazilian cancer center between January 1988 and December 2011...

BACKGROUND: Little data are available supporting the feasibility and safety of early oral feeding in patients after total gastrectomy. The aim of this study was to analyze the potential applicability of early provision of oral diet in these settings. METHODS: Medical records of 353 patients who underwent total gastrectomy for gastric cancer between 2006 and 2012 were retrospectively analyzed. Early oral feeding was defined as clear liquid diet on postoperative day (POD) 1 followed by gradual introduction of solid diet on POD 2 to 3...

BACKGROUND: The optimal surgical approach for treatment of oesophagogastric junction (OGJ) cancer is controversial. A randomized clinical trial (JCOG9502) comparing transhiatal (TH) and left thoracoabdominal (LTA) approaches was stopped after the first interim analysis owing to limited efficacy for LTA resections. Complete 10-year follow-up data are now available. METHODS: Patients with histologically proven adenocarcinoma of the OGJ or gastric cardia with oesophageal invasion of 3 cm or less were randomized to a TH or LTA approach...

BACKGROUND: A pathologic complete response (pCR) can sometimes be induced by intensive or long-term neoadjuvant chemotherapy (NAC). This prognostic research study based on a systematic review of the literature evaluated the impact of a pCR on the long-term survival of gastric cancer (GC) patients. METHODS: Articles were extracted from PubMed and the Japanese medical search engine "Ichu-shi," using the terms "GC," "NAC," and "pCR." Articles were selected based on the following criteria: (1) full-text case report, (2) R0 resection following NAC for locally advanced GC, and (3) pathological complete response in both the primary stomach and in the lymph nodes...
