A Comparison of Laparoscopic With Open Distal Gastrectomy in Advanced Gastric Cancer After Neoadjuvant Chemotherapy
- Conditions
- Gastric Cancer
- Interventions
- Drug: Neoadjuvant ChemotherapyProcedure: Laparoscopic gastrectomyProcedure: Open gastrectomyDrug: Adjuvant Chemotherapy
- Registration Number
- NCT02404753
- Lead Sponsor
- Peking University
- Brief Summary
The purpose of the study is to evaluate the safety and efficacy of laparoscopic distal D2 gastrectomy (LDG) compared with open surgery (ODG) for resectable gastric cancer, to determine whether LDG can be a test arm for a future Phase III trial to evaluate the non-inferiority of overall survival compared with ODG in patients who receive neoadjuvant chemotherapy.
- Detailed Description
The study is an open-label, controlled, randomized Phase II clinical trial. The protocol has been approved by the Ethics Committee of Beijing Cancer Hospital.
The primary endpoint is the 3-year progression-free survival (PFS) rate. The secondary endpoints are the overall survival, surgical morbidity and mortality.

- 102
- Histologically proven adenocarcinoma of the stomach.
- Clinical cT2N+M0,or cT3-4a/N+M0 disease, confirmed by upper gastrointestinal endoscopy and abdominal computed tomography (CT) and laparoscopy. The T and N stages are determined by the method of Habermann et al.
- The gastric tumors are located in the middle to lower third of the stomach, are macroscopically resectable by distal gastrectomy with D2 lymph node dissection, and R0 or R1 resection can be achieved.
- No bulky lymph node metastasis is detected by abdominal CT.
- No pleural effusion, no ascites exceeding the pelvis and no metastasis to the peritoneum, liver or other distant organs are confirmed by abdominal pelvic CT.
- No clinically apparent distant metastasis.
- Karnofsky performance status ≥70%.
- Sufficient oral intake.
- No previous treatment with chemotherapy or radiation therapy for any tumors.
- No previous surgery for the present disease.
- Sufficient organ function, as evaluated by laboratory tests 7 days or more after the date when the anticancer drugs were given. When patients are recovering from myelosuppression,the revised criteria are shown in parentheses.

- Primary Outcome Measures
Name Time Method 3-year progression-free survival 36 months In terms of locally advanced gastric cancer, to evaluate the disease free survival rate in laparoscopic subtotal gastrectomy with D2 lymph node dissection at postoperative 3 years compared with open subtotal gastrectomy with D2 lymph node dissection
- Secondary Outcome Measures
Name Time Method Overall survival 36 months In terms of locally advanced gastric cancer, to evaluate the overall survival rate in laparoscopic subtotal gastrectomy with D2 lymph node dissection at postoperative 3 years compared with open subtotal gastrectomy with D2 lymph node dissection
Surgical morbidity 30 days Surgical morbidity is defined as the events which occurs with-in postoperative 30 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.
Postoperative recovery index 2 weeks Postoperatively, the investigator evaluates the patient's recovery condition once a day. Evaluation items for patient's recovery condition: the pain score, the leaving bed time, postoperative gastrointestinal function recovery time and hospital stay.
Postoperative quality of life Up to 1 year post-operative In pre-therapy \<7 days, pre-operative \<7 days, and post-operative at 12 months after surgery, both the European Organisation for Research and Treatment of Cancer (EORTC) C30 and STO22 are analyzed with quality of life by following methods. In case of EORTC-C30, the analysis is undergone by classifying into 5 functional scales (physical, role, emotional, cognitive, and social functioning), 3 symptom scales (fatigue, pain and nausea, and vomiting), 1 global health status and 6 single items.
Surgical mortality 30 days It is defined as the death within postoperative 30 days regardless of postoperative reason. If the patient is transferred to other medication institutes with impossible condition for recovery before death, it is regarded as death.
