Totally Laparoscopic Total Gastrectomy with D2 Lymphadenectomy for Advanced Gastric Cancer

Introductions: Gastrectomy, which is the standard surgical procedure for gastric cancer, has gradually come to be performed laparoscopically. Laparoscopic distal gastrectomy (LDG) has been adopted gradually and performed for advanced gastric cancer. However, laparoscopic total gastrectomy (LTG) has not been as widely accepted as LDG due to technical difficulties, especially with reconstruction and proper D2 lymphadenectomy. The purpose of the current study was to determine the utility of TLTG with concomitant splenectomy and D2 lymphadenectomy (TLTGS) for advanced gastric cancer (AGC). Materials and Methods: Between January 2006 and May 2014, 10 consecutive patients who underwent TLTGS for AGC and 76 patients who underwent TLTG with D1 lymphadenectomy were included in this study. These two groups were compared in terms of perioperative results, with assessment of intraoperative and postoperative outcomes. Results: There were no significant differences in patients’ characteristics between the two groups. Operative time was longer in the TLTGS group than in the TLTG group. However, the rate of patients with postoperative complications including major complications was not different between the groups, and no patient in the TLTGS group had anastomotic leakage or pancreatic fistula. Conclusions: In the short-term, TLTGS had good postoperative outcomes and was useful and acceptable for AGC.

Factors associated with early recurrence after curative surgery for gastric cancer

AIM: To characterize patterns of gastric cancer recurrence and patient survival and to identify predictors of early recurrence after surgery.METHODS: Clinicopathological data for 417 consecutive patients who underwent curative resection for gastric cancer were retrospectively analyzed. Tumor and node status was reclassified according to the 7th edition of the American Joint Committee on Cancer tumor-node-metastasis classification for carcinoma of the stomach. Survival data came from both the patients' follow-up records and telephone followups.Recurrent gastric cancer was diagnosed based on clinical imaging, gastroscopy with biopsy, and/or cytological examination of ascites, or intraoperative findings in patients who underwent reoperation.Predictors of early recurrence were compared in patients with pT1 and pT2-4a stage tumors. Pearson's χ 2 test and Fisher's exact test were used to compare differences between categorical variables. Survival curves were constructed using the Kaplan-Meier method and compared via the log-rank test. Variables identified as potentially important for early recurrence using univariate analysis were determined by multivariate logistic regression analysis.RESULTS: Of 417 gastric cancer patients, 80(19.2%)were diagnosed with early gastric cancer and the remaining 337(80.8%) were diagnosed with locally advanced gastric cancer. After a median follow-up period of 56 mo, 194 patients(46.5%) experiencedrecurrence. The mean time from curative surgery to recurrence in these 194 patients was 24 ± 18 mo(range, 1-84 mo). Additionally, of these 194 patients,129(66.5%) experienced recurrence within 2 years after surgery. There was no significant difference in recurrence patterns between early and late recurrence(P < 0.05 each). For pT1 stage gastric cancer, tumor size(P = 0.011) and pN stage(P = 0.048) were associated with early recurrence of gastric tumors.Patient age, pT stage, pN stage, Lauren histotype,lymphovascular invasion, intraoperative chemotherapy,and postoperative chemotherapy were independent predictors of early recurrence in patients with pT2-4a stage gastric cancer(P < 0.05 each).CONCLUSION: Age, pT stage, pN stage, Lauren histotype, lymphovascular invasion, intraoperative chemotherapy, and postoperative chemotherapy are independent factors influencing early recurrence of pT2-4a stage gastric cancer.

Gastric cancer: Current status of lymph node dissection

D2 procedure has been accepted in Far East as the standard treatment for both early(EGC) and advanced gastric cancer(AGC) for many decades. Recently EGC has been successfully treated with endoscopy by endoscopic mucosal resection or endoscopic submucosal dissection, when restricted or extended Gotoda's criteria can be applied and D1+ surgery is offered only to patients not fitted for less invasive treatment. Furthermore, two randomised controlled trials(RCTs) have been demonstrating the non inferiority of minimally invasive technique as compared to standard open surgery for the treatment of early cases and recently the feasibility of adequate D1+ dissection has been demonstrated also for the robot assisted technique. In case of AGC the debate on the extent of nodal dissection has been open for many decades. While D2 gastrectomy was performed as the standard procedure in eastern countries, mostly based on observational and retrospective studies, in the west the Medical Research Council(MRC), Dutch and Italian RCTs have been conducted to show a survival benefit of D2 over D1 with evidence based medicine. Unfortunately both the MRC and the Dutch trials failed to show a survival benefit after the D2 procedure, mostly due to the significant increase of postoperative morbidity and mortality, which was referred to splenopancreatectomy. Only 15 years after the conclusion of its accrual, the Dutch trial could report a significant decrease of recur-rence after D2 procedure. Recently the long term survival analysis of the Italian RCT could demonstrate a benefit for patients with positive nodes treated with D2 gastrectomy without splenopancreatectomy. As nowadays also in western countries D2 procedure can be done safely with pancreas preserving technique and without preventive splenectomy, it has been suggested in several national guidelines as the recommended procedure for patients with AGC.

A matched cohort study of laparoscopy-assisted and open total gastrectomy for advanced proximal gastric cancer without serosa invasion

Background Little is known about the feasibility and safety of laparoscopy-assisted total gastrectomy （LATG） with extended lymphadenectomy in patients with advanced gastric cancer （AGC）.This study compared the technical feasibility,safety,and oncologic efficacy of LATG with open total gastrectomy （OTG） for AGC without serosa invasion.Methods From January 2009 to December 2011,235 patients underwent LATG and 153 patients underwent OTG for AGC without serosa invasion.Age,gender,and depth of invasion （pT2 and pT3） were matched by propensity scoring,and 116 patients （58 LATG and 58 OTG） were selected for analysis.Their clinicopathologic characteristics,postoperative outcomes,and survival were compared.Results There was no significant difference in clinicopathologic characteristics between the two propensity-matched groups.Median number of lymph nodes per patient was 29,and the mean number of retrieved lymph nodes was similar in the LATG and OTG groups （30.8±10.2 vs.29.0±8.3）.Peri-operative characteristics,operation time,number of transfused units per patient,and time to resumption of activities were similar in the two groups; while blood loss,times to first flatus and resumption of soft diet,and post-operative stay were significantly lower in the LATG group （P ＜0.05,respectively）.Rates of post-operative complications （12.1％ vs.15.5％） and postoperative mortality （0％ vs.1.7％）,as well as cumulative survival rates,were similar.Conclusions LATG with D2 lymphadenectomy is a safe and feasible procedure for AGC patients without serosa invasion.ProsPective.multicenter,randomized trials are needed to confirm the efficacy of LATG in this patient population.

A decade in gastric cancer curative surgery:Evidence of progress(1999-2009)

To investigate the progress in evidence-based surgical treatment of non-metastatic gastric cancer,we re- viewed the last ten years'literature.The data used in this review were identified by searches made on MED-LINE,Current Contents,PubMed,and other references taken from relevant original articles(on prospective and retrospective studies)concerning gastric cancer surgery.Only papers published in English between January 1999 and December 2009 were selected.Data from ongoing studies were obtained in December 2009, from the trials registry of the United States National Institutes of Health(http://www.clinicaltrial.gov).The citations list was presented according to evidence based relevance(i.e.,randomized controlled trials,pro- spective studies,retrospective series).In the last ten years,many challenges have been faced relating to the extension of gastric resection and nodal dissection as well as surgical timing,but we found only limited evidence,regardless of latitude of study.The ongoing phase-Ⅲ trials may provide answers that will be valid for the coming decades,and which may bring definitive answers for the currently unresolved questions.

Benefits of minimally invasive surgery in the treatment of gastric cancer

We read with great interest the article that retrospectively analyzed 814 patients with primary gastric cancer,who underwent minimally invasive R0 gastrectomy between 2009 and 2014 by grouping them in laparoscopic vs robotic procedures.The results of the study highlighted that age,American Society of Anesthesiologists status,gastrectomy type and pathological T and N status were the main prognostic factors of minimally invasive gastrectomy and showed how the robotic approach may improve long-term outcomes of advanced gastric cancer.According to most of the current literature,robotic surgery is associated with a statistically longer operating time when compared to open and laparoscopic surgery;however,looking at the adequacy of resection,defined by negative surgical margins and number of lymph nodes removed,it seems that robotic surgery gives better results in terms of the 5-year overall survival and recurrencefree survival.The robotic approach to gastric cancer surgery aims to overcome the difficulties and technical limitations of laparoscopy in major surgery.The threedimensional vision,articulation of the instruments and good ergonomics for the surgeon allow for accurate and precise movements which facilitate the complex steps of surgery such as lymph node dissection,esophagus-jejunal anastomosis packaging and reproducing the technical accuracy of open surgery.If the literature,as well as the analyzed study,offers us countless data regarding the short-term oncological results of robotic surgery in the treatment of gastric cancer,satisfactory data on long-term follow-up are lacking,so future studies are necessary.
