“…Almost half of gastric SMT is found to be gastric GIST after surgery. 13 As demonstrated in Table 3 , preoperative tumor size can predict the incidence of the level of risk of gastric GIST after surgery if the tumor is GIST and thus determine the follow-up plan. Roughly one-third of patients with gastric GIST >5.1 cm to ≤10 cm can be high risk.…”

The aim of this study was to evaluate the treatment and prognosis of gastric gastrointestinal stromal tumors (GISTs) according to the 7th UICC/AJCC tumor-node-metastasis (TNM) system and the modified National Institutes of Health (NIH) risk classification. The study cohort consisted of 1057 patients with gastric GIST who underwent surgery between January 2000 and December 2007 from 13 institutions in Korea and 2 in Japan. Clinicopathologic characteristics, surgical outcomes, recurrence, and 5-year recurrence-free survival were evaluated.The mean age of the patients was 58.6 years. Thirty patients (2.8%) had distant metastasis preoperatively. Median tumor size was 4.0 cm. Complete resection (R0 resection) was achieved in 1018 patients (96.3%). Eighty-six patients (8.1%) had postoperative complications, and 2 patients (0.2%) died within 30 days after surgery. According to the 7th UICC/AJCC TNM system, 5-year recurrence-free survival rates were 95% to 99% in stage I, 94.1% in stage II, 74.1% in stage IIIA, 48.6% in stage IIIB, and 50.0% in stage IV patients. On survival analysis of high-risk patients according to the TNM system, the 5-year recurrence-free survival rates were 91.6% in stage II, 74.1% in stage IIIA, and 48.6% in stage IIIB patients. Independent factors of recurrence following surgery for gastric GIST were gender, tumor size, mitotic count, and radicality on multivariate analysis.The treatment outcome and prognosis of gastric GIST in Korea and Japan seem more favorable compared to those in Western countries. Compared to the modified NIH risk classification, the 7th UICC/AJCC TNM system is more reflective of the 5-year recurrence-free survival of patients with gastric GIST.

“…From 2001, the information committee of the Korean Gastric Cancer Association started to analyze nationwide survey of laparoscopic gastric surgery in Korea, and the Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS group) has reported a regular survey of laparoscopic gastric surgeries from 2004 1, 11. In terms of the type of gastrectomy, LADG is the most common procedure (629 cases in 2004) 11.…”

“…In terms of the type of gastrectomy, LADG is the most common procedure (629 cases in 2004) 11. The number of laparoscopy‐assisted total gastrectomy (LATG) was rapidly increasing from 2004 (2 cases in 2001, 20 cases in 2003, 109 cases in 2004) 1, 11. On the contrary, laparoscopy‐assisted proximal gastrectomy (LAPG) or laparoscopy‐assisted pylorus‐preserving gastrectomy (LAPPG) was rarely conducted (11 cases for LAPG, 1 case for LAPPG in 2004) 11.…”

“…The advantages of minimally invasive approaches are less postoperative pain, better cosmesis, less inflammatory reaction, rapid recovery of bowel function, well‐preserved immune function, short hospital stay, and a rapid return to normal social activity. Laparoscopic surgery in Korea increased rapidly after 2001 because the development of diagnostic tools and nationwide mass health screening increased the detection of early gastric cancer (28.6% in 1995, 47.4% in 2004, and 57.7% in 2009) 1, 2. In addition, medical insurance began to cover laparoscopic surgery for gastric adenocarcinoma since 2006.…”

Laparoscopic surgery in Korea increased rapidly because of the early detection of gastric cancer by the development of diagnostic tools and nationwide screening. The Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS group) played a leading role in various projects related with minimally invasive surgery. The justification of minimally invasive procedures including robotic surgery, sentinel-node biopsy, or single-port surgery/Natural Orifice Transluminal Endoscopic Surgery (NOTES) must be predetermined by the clinical trial before a wide application, and the medical industry as well as surgeons should have great responsibility.

“…In Korea and Japan, the proportion of patients undergoing laparoscopic-assisted distal gastrectomy is rapidly increasing in recent years for the treatment of EGC because this procedure allows the surgeon to perform a limited lymph node dissection [58]. Treatment results of a relatively large number of patients who have undergone laparoscopically assisted distal gastrectomy showed that the operative time was acceptable and there were no significant complications.…”

Minimally invasive treatment for gastric cancer: Approaches and selection process

Minimally invasive treatment of gastric cancer has emerged as a result of the technical advances, better understanding of gastric physiology, and more knowledge of the biologic behavior of gastric cancer. This treatment results in improved quality of life embodied by smaller incisions, reduced length of hospital stay, and a faster return to productive life. However, minimally invasive treatment for gastric cancer must take into consideration the potential effects of these techniques on tumor dissemination at the time of the treatment procedure, as well as the rates of recurrence and overall survival. Several technical treatment approaches to gastric cancer have now become possible, utilizing endoscopy, laparoscopy, or an open method. Endoscopic mucosal resection (EMR), limited resection, and laparoscopic surgical resection are the currently practiced modalities as the minimally invasive treatment. Lymph node dissection with the minimally invasive techniques is a barrier to its wide application. Although it is not commonly performed in Western countries, the use of minimally invasive treatment for gastric cancer is growing, especially in Korea and Japan. Minimally invasive treatment for early gastric cancer (EGC) has already been shown to be safe and effective in many retrospective series though no prospective randomized studies comparing it to open resection have been performed. Therefore, routine implementation of these procedures must await confirmatory outcomes generated by well-done randomized prospective clinical trials.
