Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This CLASS02-01 trial is a prospective, multicenter trial for laparoscopic total gastrectomy (LTG) and open total gastrectomy (OTG) in patients with clinical stage I (T1N0M0、T1N1M0、T2N0M0) gastric cancer. The primary purpose of this study is to evaluate the early operative morbidity and mortality and determine the safety of LTG compared with OTG for clinical stage I gastric adenocarcinoma. The second purpose is to evaluate the recovery course and compare the postoperative hospital stay of the patients enrolled in this study.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Gastric cancer is an important health problem, being the fourth most common cancer and the third leading cause of cancer-related death worldwide. Age standardized mortality rates for gastric cancer are 14.3 per 100 000 in men and 6.9 per 100 000 in women. Incidence shows clear regional and sex variations-rates are highest in Eastern Asia, Eastern Europe, and South America and lowest in Northern and Southern Africa. More than 679 000 new cases and 498,000 deaths occur every year in China, and an increasing trend of proximal gastric cancer is observed during the past years.
More than 20 years after the introduction of laparoscopic gastrectomy, many large-scale randomized controlled trials have been conducted in Japan (JCOG0912 and JLSSG0901), Korea (KLASS01 and KLASS02), and China (CLASS01). These trials are all designed to evaluate the non-inferiority of laparoscopic-assisted distal gastrectomy (LADG) to its open counterpart. No RCT for laparoscopic total gastrectomy (LTG) exists at this moment. The standardization of techniques for esophagojejunal anastomosis in LTG has been difficult even for experienced surgeons.
At present, Japan (JCOG1401), Korea (KLASS03), and Netherlands (STOMACH) have planned or launched clinical studies on LTG. China is one of the countries with the highest incidence of gastric cancer and surgeons have accumulated extensive experience through CLASS01 study. So, it's time for conducting the clinical research on the safety of LTG for gastric cancer.
