conferenceObject OUTCOME OF GASTRIC CANCER PATIENTS SUBMITTED TO D1 LYMPH NODE DISSECTION DUE TO UNFAVORABLE MEDICAL CONDITIONS(2017) RAMOS, Marcus Kodama; PEREIRA, Marina; DIAS, Andre R.; YAGI, Osmar K.; BARCHI, Leandro C.; JACOB, Carlos E.; MUCERINO, Donato R.; LOPASSO, Fabio; MESTER, Marcelo; BRESCIANI, Claudio C.; CHARRUF, Amir Z.; ZILBERSTEIN, Bruno; CECCONELLO, Ivan; RIBEIRO, Ulysses- Resultados da gastrectomia D2 para o câncer gástrico: dissecção da cadeia linfática ou ressecção linfonodal múltipla?(2012) ZILBERSTEIN, Bruno; MUCERINO, Donato Roberto; YAGI, Osmar Kenji; RIBEIRO-JUNIOR, Ulysses; LOPASSO, Fabio Pinatel; BRESCIANI, Claudio; JACOB, Carlos Eduardo; COIMBRA, Brian Guilherme Monteiro Marta; CECCONELLO, IvanBACKGROUND: Eastern literature is remarkable for presenting survival rates for surgical treatment of gastric adenocarcinoma superior to those presented in western countries. AIM: To analyze the long-term result after D2 gastrectomy for gastric cancer. METHODS: Two hundred seventy four underwent gastrectomy with D2 lymph node dissection as exclusive treatment. The inclusion criteria were: 1) lymph node removal according to Japanese standardized lymphatic chain dissection; 2) potentially curative surgery described in medical records as D2 or more lymph node dissection; 3) tumoral invasiveness of gastric wall restricted to the organ (T1 - T3); 4) absence of distant metastasis (N0-N2/M0); 5) a minimum of five years follow-up. Clinical pathological data included sex, age, tumor location, Borrmann's macroscopic tumor classification, type of gastrectomy, mortality rates, hystological type, TNM classification and staging according to UICC TNM 1997. RESULTS: Total gastrectomy was performed in 77 cases (28.1%) and subtotal gastrectomy in 197 (71.9%). The tumor was located in the upper third in 28 cases (10.2%), in the middle third in 53 (19.3%), and in the lower third in 182 (66.5%). Among patients that had their Borrmann's classification assigned, five cases (1.8%) were BI, 34 (12.4%) BII, 230 (84.0%) BIII and 16 (5.9%) BIV. Tumors were histologically classified as Laurén intestinal type in 119 cases (43.4%) and as diffuse type in 155 (56.6%). According to UICC TNM 1997 classification, early gastric cancer (T1) was diagnosed in 68 cases (24.8 %); 51 (18.6%) were T2, and 155 (56.6%) were T3. No lymph node involvement (N0) was observed in 129 cases (47.1%), whereas 100 (36.5%) were N1 (1-6 lymph nodes), and 45 (16.4%) were N2 (7-15 lymph nodes).The median number of lymph nodes dissected was 35. The overall long-term (five-year) survival rate, for stages I to IIIb was 70.4%. CONCLUSION: Digestive surgeons must be stimulated in performing D2 gastrectomies to avoid wasting the only treatment to gastric adenocarcinoma that has proven to be efficient up to this days. It must be emphasized that standardized lymph nodes dissection according to tumor location is more important that only the number of removed nodes

Since then, the experience with this kind of approach has grown, aiming to provide the same oncological outcomes and survival to conventional surgery. Regarding gastric cancer, surgery is still considered the only curative treatment, considering the extent of resection and lymphadenectomy performed. Conventional surgery remains the main modality performed worldwide. Notwithstanding, the role of the minimally invasive access is yet to be clarified. Objective: To evaluate and summarize the current status of minimally invasive resection of gastric cancer. Methods: A literature review was performed using Medline/PubMed, Cochrane Library and SciELO with the following headings: gastric cancer, minimally invasive surgery, robotic gastrectomy, laparoscopic gastrectomy, stomach cancer. The language used for the research was English. Results: 28 articles were considered, including randomized controlled trials, meta-analyzes, prospective and retrospective cohort studies. Conclusion: Minimally invasive gastrectomy may be considered as a technical option in the treatment of early gastric cancer. As for advanced cancer, recent studies have demonstrated the safety and feasibility of the laparoscopic approach. Robotic gastrectomy will probably improve outcomes obtained with laparoscopy. However, high cost is still a barrier to its use on a large scale.
- Predicting recurrence after curative resection for gastric cancer: External validation of the Italian Research Group for Gastric Cancer (GIRCG) prognostic scoring system(2016) BARCHI, L. C.; YAGI, O. K.; JACOB, C. E.; MUCERINO, D. R.; RIBEIRO JR., U.; MARRELLI, D.; ROVIELLO, F.; CECCONELLO, I.; ZILBERSTEIN, B.Background: Most nomograms for Gastric Cancer (GC) were developed to predict overall survival (OS) after curative resection. The Italian Research Group for Gastric Cancer (GIRCG) prognostic scoring system (PSS) was designed to predict the recurrence risk after curative treatment based on pathologic tumor stage and treatment performed (D1 D2/D3 lymphadenectomy). This study was carried out to externally validate the GIRCG's PSS. Patients and methods: Adopting the same criteria used by GIRCG to build the PSS, 185 patients with GC operated with curative intention were selected. The median follow-up period was 77.8 months (1.93-150.8) for all patients and 102.5 months (60.9-150.8) for patients free of disease. The NRI (net reclassification improvement) was calculated to estimate the overall improvement in the reclassification of patients using the PSS in place of the TNM stage system. Results: GC recurrence occurred in 70 (37.8%) patients. The mean time to recurrence was 22.2 (range 1.9-98.1) months. For patients with recurrence, the gain in the proportion of reclassification was 0.257 (p < 0.001), indicating an improvement of 26%. For patients without recurrence, the gain in the proportion of reclassification was 0.122 (p < 0.001), indicating a worsening of 12%. The NRI calculated was 0.135 (p = 0.0527). Conclusion: The GIRCG's PSS, which predicts the likelihood of recurrence after radical surgical treatment for GC, is more accurate than TNM system to predict recurrence mainly for high-risk patients. Yet, the PSS does not have the same effectiveness for low-risk patients, overestimating the chance of recurrence occurs even for disease-free patients.
