A Comparison Laparoscopic With Open Gastric Cancer Surgery for Locally Advanced Gastric Cancer
- Conditions
- Gastric Cancer
- Interventions
- Procedure: Open SurgeryProcedure: Laparoscopic procedures
- Registration Number
- NCT02748551
- Lead Sponsor
- Moscow Clinical Scientific Center
- Brief Summary
Nowadays, the proportion of patients with locally advanced gastric cancer is estimated up to 90 percent of all gastric cancer cases in Russian Federation. Surgical procedure with D2 Lymphadenectomy is the main option for treatment. Conventional open approach is still the current standard for advanced gastric cancer. Laparoscopic procedures for gastric cancer as minimally invasive surgery has gained popularity for the treatment of early gastric cancer in East Asia. Several studies indicated that laparoscopic procedures both total and subtotal gastrectomy with D2 lymphadenectomy is a technically feasible and safe procedure by experienced surgeons in high-volume specialized hospitals. However, lack of solid evidence on the oncologic efficacy.
Starting clinical trials for evaluate safety of oncology laparoscopic subtotal gastrectomy for locally advanced gastric cancer. Aim of this trial is show safety, feasibility and oncologic efficacy of Laparoscopic radical surgical procedures both total and subtotal gastrectomy for treatment gastric cancer.

Group Intervention Description Laparoscopic surgery Open Surgery Traditional open procedure for patient with locally advanced gastric cancer Open surgery Laparoscopic procedures Minimum invasive procedure (laparoscopic) for patient with locally advanced gastric cancer
- Primary Outcome Measures
Name Time Method "Major" Surgical Morbidity 21 days. "Major" Surgical morbidity is defined as the complication grade on III-V Clavien-Dindo Classification which occurs with-in postoperative 21 days, extension of hospitalization and re-hospitalization. It is necessary to evaluate the complication and if it occurs during the hospitalization, it is required to record complication name, date of on-set (postoperatively), grade on Clavien-Dindo Classification and treatment for complication.
- Secondary Outcome Measures
Name Time Method Postoperative recovery index 10 days Time to first ambulation, flatus, liquid diet, soft diet, and duration of hospital stay are used to assess the postoperative recovery course The amount of abdominal drainage and blood transfusion are also recorded
3-year progression-free survival 36 months In terms of locally advanced gastric cancer, to evaluate the progression-free survival rate in laparoscopic gastrectomy with D2 lymph node dissection at postoperative 3 years compared with open procedures
Surgical Mortality 90 days It is defined as the death within postoperative 90 days regardless of postoperative reason.
Pain scores up to 3 days after surgery Pain scores based on a visual analog scale the day of surgery and the subsequent 3 days postoperative 1 days, 2 days, 3 days
3-year overall survival 6, 12, 18, 24, 30 and 36 months In terms of locally advanced gastric cancer, to evaluate the overall survival rate in laparoscopic gastrectomy with D2 lymph node dissection at postoperative 3 years compared with open procedures
Peri-operative blood loss 1 day Minimally-invasive surgery is associated with less peri-operative blood loss. Blood loss will be measured in milliliters and average blood loss will be compared to the conventional 'open' group.
5-year overall survival rate 6, 12, 18, 24, 30, 36, 48 and 60 months In terms of locally advanced gastric cancer, to evaluate the overall survival rate in laparoscopic gastrectomy with D2 lymph node dissection at postoperative 5 years compared with open procedures
long-term surgical morbidity 21days - 36 months after surgery Surgical morbidity is defined as the events which occurs with-in postoperative 21 days - 36 months after surgery. It is necessary to evaluate the complication, it is required to record complication name, date of on-set. Long complications are included: hernia, bleeding, bowel obstruction etc.
Extent of lymph node dissection 2 weeks The extent of lymph node dissection in treatment of gastric cancer is considered a prognostic marker for postoperative survival and disease-free survival. Before implementation of a new surgical technique, it is imperative that this technique is non-inferior with regard to the extent of lymph node dissection. Measures will include the number of resected lymph nodes and the number of resected lymph node stations.
Postoperative quality of life 6, 12, 18, 24, 30 and 36 months Both the European Organization for Research and Treatment of Cancer (EORTC) C30 and STO22 are analyzed with quality of life
