Abstract

Sentinel node navigation surgery (SNNS) has become a standard procedure for early‑stage melanoma and breast cancer. However, very few studies have evaluated the long‑term clinical outcomes following SNNS for gastric cancer. The present study analyzed 51 patients with cT1 gastric cancer who underwent SNNS at our hospital. Sentinel nodes (SNs) were identified using the dual tracer method. Patients underwent limited gastrectomy with SN station dissection when the SNs were reported as pathologically negative during surgery. When SNs were pathologically positive, standard gastrectomy with D2 lymphadenectomy was performed. Out of the 51 cases, 42 cases (82%) were pathologically diagnosed as SN‑negative using a frozen section. The surgical procedures included segmental gastrectomy (n=33) and local resection (n=9). A total of 9 patients (18%) had lymph node metastasis in SNs. The mean observation period was 3,125±167 days, and the 5‑year overall survival rate was 98%. There was no recurrence, and body weight loss was minimal following the SNNS. Remnant gastric cancer developed in 4 (8%) of the 50 patients except total gastrectomy. Thus, SNNS was a useful procedure for cT1 gastric cancer from the long‑term clinical outcomes, though metachronous gastric cancer should paid further attention to.
