About this study
Official title: Laparoscopic Gastric Function Preserving Surgery Combined With Resection of the Anterior Lymphatic Drainage Area. Comparison of Laparoscopic Standard Radical Gastric Cancer Surgery for Early Distal Gastric Cancer Multicenter, Prospective, Randomized, Open, Parallel-controlled, Non-inferiority Efficacy Clinical Trial
Nowadays, while pursuing the eradication of tumor, how to maximize the preservation of normal anatomy and physiological functions of the stomach, reduce the surgical trauma caused by excessive debridement, and improve the quality of life of patients after surgery has become a more important concern in the treatment of early gastric cancer. This prospective multicenter randomized controlled clinical trial was designed to elucidate the oncologic safety of laparoscopic gastric preservation surgery compared to standard laparoscopic gastrectomy. The oncologic safety of laparoscopic gastric preservation surgery with anterior basal dissection (SBD) compared to standard laparoscopic gastrectomy. This trial is an investigator-initiated, multicenter, prospective, randomized, open, parallel-controlled with a non-inferiority design. Patients diagnosed as distal gastric cancer with clinical stage T1N0M0, with a lesion diameter of 3 cm or less were eligible to participate in this study. Patients will be randomized to either laparoscopic stomach-preserving surgery with SBD or standard surgery. The primary end-point is 3-year disease-free survival.

What participants receive

Laparoscopic gastric function preserving surgery combined with resection of the anterior lymphatic drainage areaProcedure or surgery
A 4mL volume of double tracer is injected into the submucosa of the four quadrants of the primary tumor by intraoperative gastroscopic method., and 15 minutes after gastroscopic tracer injection, the green anterior lymph nodes were carefully dissected and removed from the surgical area and evaluated for lymph node metastasis by parallel intraoperative freezing.If all collected anterior lymph nodes are negative, laparoscopic gastric function preserving surgery will be performed.

ICG injection: A 4mL volume of double tracer is injected into the submucosa of the four quadrants of the primary tumor by intraoperative gastroscopic method. 0.5 mL was injected at each site, and 15 minutes after gastroscopic tracer injection, the green anterior lymph nodes were carefully dissected and removed from the surgical area and evaluated for lymph node metastasis by parallel intraoperative freezing.
2. Intraoperative and postoperative pathological examination Intraoperative histological examination of lymph nodes collected from the anterior lymph node pool was performed, If all collected anterior lymph nodes are negative, laparoscopic gastric function preserving surgery will be performed.

What is being measured
The primary outcome is the main question the study is designed to answer.
Disease-free survival (DFS) at three years
The criteria for DFS events in this study were as follows: recurrence of the primary tumor at the incisional margin or anastomosis, heterochronic metastasis in the remnant stomach, histologically or imaging confirmed intraperitoneal recurrence, lymph node metastasis, distant metastasis, new malignancy in other organs, and other causes of death.
Measured: three years

Nowadays, while pursuing the eradication of tumor, how to maximize the preservation of normal anatomy and physiological functions of the stomach, reduce the surgical trauma caused by excessive debridement, and improve the quality of life of patients after surgery has become a more important concern in the treatment of early gastric cancer. This prospective multicenter randomized controlled clinical trial was designed to elucidate the oncologic safety of laparoscopic gastric preservation surgery compared to standard laparoscopic gastrectomy. The oncologic safety of laparoscopic gastric preservation surgery with anterior basal dissection (SBD) compared to standard laparoscopic gastrectomy. This trial is an investigator-initiated, multicenter, prospective, randomized, open, parallel-controlled with a non-inferiority design.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 9 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
