 CURRENT SITUATION AND FUTURE OF THE GASTRIC CANCER SURGERY

 According to the 2018 World Health Organization (WHO) data, gastric cancer is the fourth most common cancer in all age groups and both sexes. It is the third leading cause of cancer mortality worldwide. Despite recent developments in medicine, the likelihood of developing gastric cancer increases with advanced age, as the life expectancy has increased in most countries.

 Theodor Billroth did the first successful open gastrectomy in 1881 for gastric cancer. Open gastrectomy (OG) has been used as the standard surgical technique for many years in treating gastric cancer. In 1981, the Japanese Research Society for the Study of Gastric Cancer provided guidelines for the standardization of surgical  treatment  of gastric cancer. Since then, gastrectomy-related D2 lymph node dissections have become the standard in Japan. D2 is a complicated and challenging surgical technique, and proper training is mandatory even in open gastrectomy.

  Over the past three decades, minimally invasive surgery (MIS) has become popular. In early  periods of MIS laparoscopic technique  was  used for gastric cancer. For the last decade, the use of robotic surgery has become widespread worldwide thanks to its favorable early and late outcomes. The main advantages of MIS include less postoperative pain, shorter length of hospital stay, and improved long-term quality of life. It has been shown that MIS is an effective and safe treatment method for early gastric cancer. Although data is limited, it can be successfully performed with favorable early oncological outcomes for advanced stages. Robotic gastrectomy is superior to laparoscopic gastrectomy with better intraabdominal visualization, less intraoperative bleeding, and similar morbidity rates. However, prolonged surgery periods and higher cost are the main disadvantages of robotic gastrectomy. Technical difficulties in D2 lymphadenectomy and performing intracorporeal anastomosis  constitute obstacles in applying minimally invasive surgery. Robotic surgery may decrease these technical challenge and provide better surgical and oncologic outcomes.

 This lecture aims to give information about the current situation and future of gastric cancer surgery. The importance and usefulness of MIS are increasing in gastric cancer surgery.
