With analyzing lymphatic spread patterns based on cross-sectional tumor location, we planned to predict the surgical burden of LN#6 dissection, balancing oncological safety and risk of postoperative complications.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>We included consecutive PPG cases at Seoul National University Hospital (2007\u20132017) to assess the incidence, 5-year survival rate (5YSR), and 3-year recurrence-free survival (3RFS) of LN#6 metastasis. Cox regression analyzed the impact of LN#6 metastasis itself on 5YSR and 3RFS. The effect of tumor location among gastric middle-third tumors on LN#6 metastasis was evaluated. The therapeutic indices (TI) of LN#6 based on tumor location were calculated.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Among 1070 PPG patients, 5YSR and 3RFS were 97.0% and 98.9%. LN#6 metastasis was found in 11 patients (1.03%), with 3 recurrences observed among them (3\/11, 0.28%). LN#6 metastasis itself did not significantly affect 5YSR (<jats:italic>p<\/jats:italic>\u2009=\u20090.266) or 3RFS (<jats:italic>p<\/jats:italic>\u2009=\u20090.075). Tumor location showed a significant association for LN#6 metastasis (<jats:italic>p<\/jats:italic>\u2009=\u20090.015), with low body greater curvature (LB-GC) showing the highest prevalence (5\/11, 45.45%). TI of LN#6 for LB-GC tumors was 3.76, while TI for low body lesser curvature (LB-LC) and midbody lesser curvature (MB-LC) tumors was 0.0.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>LN#6 metastasis is infrequent and does not affect 5YSR or 3RFS in PPG patients.
