Evaluation of postoperative quality of life by PGSAS-45 following local gastrectomy based on the sentinel lymph node concept in early gastric cancer



The usefulness of sentinel node navigation surgery (SNNS) for early gastric cancer has been demonstrated in a multicenter prospective study. However, quality of life (QOL) after local resection remains unclear. This present study investigated QOL after local resection and distal gastrectomy.


We examined 69 patients who underwent laparoscopic distal gastrectomy (LADG) (n = 44) and laparoscopic local resection (LLR) (n = 25) in our hospital between September 2011 and May 2018. We conducted a combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique (CLEAN-NET) with SNNS as LLR. All patients had pStage I or II and none had received adjuvant chemotherapy. We evaluated QOL using the postgastrectomy syndrome assessment scale questionnaire (PGSAS-45) 1, 6, and 12 months after surgery.


In PGSAS-45, no significant differences were observed between LLR and LADG at 1 and 6 months after surgery. At 12 months, the LLR group scored better for some of the subscales (SS). In the endoscopic evaluation, the LLR group showed significant improvements in residual gastritis at 6 months (P = 0.006) and esophageal reflux and residual gastritis at 12 months (P = 0.021 and P = 0.017). A significant difference was observed in the prognostic nutritional index, which was assessed using serum samples, between the two groups at 6 months (P = 0.028). The body weight ratio was better in the LLR group than in the LADG group at 6 and 12 months (P = 0.041 and P = 0.007, respectively).


CLEAN-NET with SNNS preserved a better QOL and nutrition status than LADG in patients with early gastric cancer.
