- Abstract
Background: Clinical benefits of the meso-jejunal lymph node (MJLN) dissection in remnant gastric cancer (RGC) patients have not been fully established. Hence, in this retrospective study, we evaluated the survival benefit of MJLN dissection and prognostic significance of MJLN metastasis in RGC patients who underwent gastrojejunostomy reconstruction after their initial gastrectomy. Methods: We retrospectively reviewed 391 patients who underwent surgery for RGC at our institution between 1996 and 2019. Among them, 60 patients had MJLN dissection. The index value of the survival benefit gained by dissection of the MJLN was calculated by multiplying the frequency of metastasis at the MJLN station and the 5-year overall survival rate (5YOS) of patients with metastasis at that station. When the metastatic rate or 5YOS exceeded 10%, dissection was recommended. An index value of dissection greater than 1.0 was considered significant. Results: Total metastatic rate of MJLN was 35% (n = 21/60). Patients with MJLN metastasis had advanced pathologic stage compared to patients in the no-metastasis group (p < 0.001). In T2-T4 RGC patients, the metastatic rate of MJLN was 48.6% (n = 17/35), and their 5YOS was 28.4%. The calculated index value was 13.8. Also, patients with MJLN metastasis had a poorer overall survival than those without metastasis. MJLN metastasis was an independent prognostic factor of overall survival in multivariate analysis (HR 6.77, 95%CI 2.21–20.79, p = 0.001). Conclusion: MJLN dissection should be considered for advanced RGC patients who underwent gastrojejunostomy after distal gastrectomy during their initial surgery according to the index value.
