Maintaining the postoperative quality of life (QOL) while ensuring curability without overtreatment is important in the treatment of early gastric cancer. Postoperative QOL is anticipated to be maintained through minimally invasive function-preserving gastrectomy in early gastric cancer. The concept of the sentinel lymph node (SN) basin is essential to maintain the curability of early gastric cancer using minimally invasive function-preserving gastrectomy. However, additional resection after surgery is difficult to perform in gastric cancer. Thus, the SN basin theory is important. Recently, a multicenter randomized phase III trial in South Korea (SENORITA trial) proved that laparoscopic sentinel node navigation surgery (LSNNS) for stomach preservation results in better postoperative QOL compared with standard gastrectomy in patients with early gastric cancer. LSNNS contributes to patients' QOL based on the concept that curability is not impaired. A multicenter nonrandomized phase III trial is ongoing in Japan, and oncologic safety is expected to be demonstrated. LSNNS has been established as a treatment option for selected patients with early gastric cancer, and its application will become widespread in the future.

早期胃癌前哨淋巴结导航手术的最新进展。

维持术后生活质量 (QOL)，同时确保可治愈性，避免过度治疗，对于早期胃癌的治疗非常重要。术后 QOL 有望通过早期胃癌的微创功能保留胃切除术得以维持。前哨淋巴结 (SN) 盆地的概念对于使用微创功能保留胃切除术维持早期胃癌的可治愈性至关重要。然而，手术后的额外切除术在胃癌中很难进行。因此，SN 盆地理论很重要。最近，韩国的一项多中心随机 III 期试验（SENORITA 试验）证明，与早期胃癌患者的标准胃切除术相比，用于胃保留的腹腔镜前哨淋巴结导航手术 (LSNNS) 具有更好的术后 QOL。LSNNS 基于不损害可治愈性的概念，有助于提高患者的生活质量。日本正在进行一项多中心非随机 III 期试验，预计将证明其肿瘤学安全性。LSNNS 已被确定为早期胃癌患者的一种治疗选择，其应用将在未来得到广泛应用。肿瘤安全性有望得到证明。LSNNS 已被确定为早期胃癌患者的一种治疗选择，其应用将在未来得到广泛应用。肿瘤安全性有望得到证明。LSNNS 已被确定为早期胃癌患者的一种治疗选择，其应用将在未来得到广泛应用。
