Background: To explore the efficacy of treatment strategies for non-metastatic gastric linitis plastica (GLP).
Methods: Patients with non-metastatic GLP from 2004 to 2014 were identified from the National Cancer Database (NCDB). We compared overall survival (OS) of those patients who received different treatments, including surgery alone, a combination of surgery with chemotherapy and/or radiotherapy (S + C/R), chemotherapy and/or radiotherapy (C/R), and no treatment.
Results: The cohort included 474 patients with non-metastatic GLP. Overall, the median survival was significantly different among four groups (13.90 months in S + C/R, 8.38 months in surgery alone, 8.94 months in C/R and 2.50 months in no treatment). Then, we compared the efficacy of surgery alone and surgery with postoperative chemotherapy and/or radiotherapy (S + post C/R). When the tumor size was greater than 8 cm in stage III patients, S + post C/R was associated with a better survival benefit than surgery alone. S + post C/R also conferred an obvious survival advantage compared to surgery alone for R0 patients with positive lymph nodes and patients with positive margins.
Conclusions: Surgery plays the fundamental role in improving the OS of patients with non-metastatic GLP. S + post C/R would benefit patients in stage III with large-sized tumors (>8 cm), patients with negative margins and positive lymph nodes, and/or patients with positive margins.
