Multivisceral Resection for Locally Advanced Gastric Cancer: An Italian Multicenter Observational Study.
ABSTRACT IMPORTANCE The role of multivisceral resection, in the setting of locally advanced gastric cancer, is still debated. Previous studies have reported a higher risk for perioperative morbidity and mortality, with limited objective benefit in terms of survival. Conversely, recent studies have shown the feasibility of enlarged resections and the potential advantage of extended resection for clinical stage T4b gastric adenocarcinoma with good long-term results. OBJECTIVE To analyze the role of multivisceral resection for locally advanced gastric cancer with particular attention to the brief and long-term results and to the prognostic value of clinical and pathologic factors. DESIGN Prospective multicenter study using data from between January 1, 1995, and December 31, 2008. SETTINGS Seven Italian surgery centers. PATIENTS A total of 2208 patients underwent curative resections for gastric carcinoma at the centers. Among them, 206 patients presented with a clinical T4b carcinoma. One hundred twelve underwent a combined resection of the adjacent organs with a gastrectomy owing to suspicion or direct invasion of these organs by the gastric cancer. MAIN OUTCOMES AND MEASURES Clinical and pathologic variables were prospectively collected and the feasibility and efficacy of multivisceral resection for locally advanced clinical T4b gastric cancer were assessed. RESULTS Postoperative mortality and complication rates of patients who underwent a gastrectomy with a combined resection of the involved organs were 3.6% and 33.9%, respectively. Pathologic factors revealed that the nodal involvement was present in about 89.3% of patients and the mean (SD) number of pathologic lymph nodes was 14.8 (16.6). The overall 5-year survival rate was 27.2%. The completeness of resection and lymph node invasion represent independent prognostic parameters at multivariate analysis. CONCLUSIONS AND RELEVANCE Our study indicates that patients undergoing extended resections experience acceptable postoperative morbidity and mortality rates, and an en bloc multivisceral resection should be performed in patients when a complete resection can be realistically obtained and when lymph node metastasis is not evident.

ABSTRACT: BackgroundThe aim of the present study was to identify temporal trends in long-term survival and postoperative outcomes and to analyze prognostic factors influencing the prognosis of patients with gastric cancer (GC) treated in a 30-year interval in a tertiary referral Western institution.MethodsBetween January 1980 and December 2010, 1,278 patients who were diagnosed with GC at the Digestive Surgery Department, Catholic University of Rome, Italy, were identified. Among them, 936 patients underwent surgical resection and were included in the analysis.ResultsOver time there was a significant improvement in postoperative outcomes. Morbidity and mortality rates decreased to 19.4% and 1.6%, respectively, in the last decade. By contrast, the multivisceral resection rate steadily increased from 12.7% to 29.6%. The overall five-year survival rate steadily increased over time, reaching 51% in the last decade, and 64.5% for R0 resections. Multivariate analysis showed a higher probability of overall survival for early stages (I and II), extended lymphadenectomy, and R0 resections.ConclusionsOver three decades there was a significant improvement in perioperative and postoperative care and a steady increase in overall survival.World Journal of Surgical Oncology 07/2014; 12(1):217.

ABSTRACT: Most studies about complication after gastric cancer surgery have been performed without consideration of the severity of each complication. The purposes of this study were to prospectively analyze all postgastrectomy complications according to severity using Clavien-Dindo classification and to identify risk factors related to postoperative complications. Complication data were collected prospectively through weekly conferences with all gastric adenocarcinoma patients who underwent gastrectomy between March 2011 and February 2012 at Seoul National University Hospital. Complications were categorized according to the Clavien-Dindo classification. Out of the 881 patients who underwent gastrectomy, there were 254 events in 197 patients (22.4 %). The numbers of grade I, II, IIIa, IIIb, IVa, and V complications according to the Clavien-Dindo classification were 71 (8.1 %), 58 (6.6 %), 108 (12.3 %), 8 (0.9 %), 5 (0.6 %), and 4 (0.5 %), respectively. Extended gastrectomy (odds ratio [OR], 3.92; 95 % confidence interval [CI], 1.96-7.82, p < 0.001), total gastrectomy (OR, 1.97; 95 % CI, 1.24-3.14, p = 0.004), and age of 60 years or more (OR, 1.66; 95 % CI, 1.15-2.38, p = 0.007) were found to be significant independent risk factors for overall complications of gastrectomy. These three factors were also risk factors for the complications of grade IIIa or over and local and systemic complications. In addition, ASA 3 or 4 and moderate or severe malnutrition as well as those three factors were risk factors for systemic complications. Age and the extent of gastrectomy were revealed as the prognostic factors for overall complications and the complications of grade IIIa or over according to the Clavien-Dindo classification following gastrectomy for gastric cancer.Journal of Gastrointestinal Surgery 05/2014; 18(7).

ABSTRACT: The Clavien-Dindo classification for postoperative complications has been established as a standardized system and applied in many fields of surgery. The aim of our study was to assess the complications after total gastrectomy using the Clavien-Dindo classification and identify risk factors related to them. Four hundred and fifteen patients who underwent total gastrectomy for gastric cancer between April 2009 and September 2014 were enrolled in this study. Postoperative complications were graded, and possible risk factors related to complications were analyzed. The overall complication rate was 13.3 %, with the severe complications classified as grade III or above accounting for 3.1 %. Age of 65 years old or more, higher TNM staging, and open surgery were identified as independent risk factors for overall complications. Age of 65 years old or more, ASA score of 3 or more, multiorgan resection, and retrieved lymph nodes of 30 or more were identified as independent risk factors for severe complications. The Clavien-Dindo system has a broad applicability and facilitates the assessment on the incidence and severity of complications. Large-scaled, prospective clinical trials using the classification are necessary to evaluate the postoperative complications of total gastrectomy for gastric cancer.Medical Oncology 04/2015; 32(4):573.
