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.

- "The constant increase of multivisceral resections in our series can be explained by the more aggressive surgical approach in the case of locally advanced GC and in the suspicion of direct invasion of adjacent organs. As reported by a recent Italian multicenter observational study , 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.

The 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.
Between 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.
Over 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.
Over three decades there was a significant improvement in perioperative and postoperative care and a steady increase in overall survival.

ABSTRACT: With the exception of tumours limited to the mucosa, surgical resection of the primary tumour and its local lymph node metastases still remains the sole option for a curative therapy for potentially resectable gastric cancer, as long as a complete tumour resection (R0 resection) can be performed. In this context, the extent of surgical radicality has been discussed over the last years, especially based on the following aspects: 1. extent of lymphadenectomy/need for splenectomy; 2. subtotal versus total gastrectomy; 3. surgical therapy for cardia cancer; 4. operative approach in cT4-tumours; 5. laparoscopic versus open surgery. Based on the recent study results as well as the current guidelines, this review will discuss these specific issues and gives an insight about the recommended surgical radicality in gastric cancer.
