Kim KH, Lee SH, Choi CW, Kim SJ, Choi CI, Kim DH, Jeon TY, Kim DH, Hwang SH - Ann Surg Treat Res (2015)

Bottom Line: We compared MGC versus nonmucinous gastric adenocarcinoma (NMGC).LEMPC patients showed similar features compared with NMGC patients.It is reasonable to consider LEMPC patients in the diagnostic criteria of MGC, and to adequately treat.

ABSTRACT

Purpose: Mucinous gastric adenocarcinoma (MGC) is defined by the World Health Organization as a gastric adenocarcinoma with >50% extracellular mucin pools within the tumors. In this study, we attempted to analyze the clinicopathologic features of patients pathologically diagnosed as gastric cancer with lower than 50% tumor volume of extracellular mucin pool adenocarcinoma (LEMPC). We compared MGC versus nonmucinous gastric adenocarcinoma (NMGC). We were used in abbreviations LEMPC for NMGC including extracellular mucin pool.

Methods: Files of 995 patients with gastric cancer NMGC (n = 935), MGC (n = 20), LEMPC (n = 40) who underwent curative resection at Pusan National University Yangsan Hospital from December 2008 to December 2013 were retrospectively analyzed. All pathologic reports after curative resection and evaluated clinicopathologic features were reviewed to identify the effect of extracellular mucin pools in gastric cancer.

Results: Compared with the NMGC patients, the clinicopathological features of MGC patients were as follows: more frequent open surgery, larger tumor size, more advanced T stage and N stage, more positive lymph node metastasis, and perineural invasion. LEMPC patients showed similar features compared with NMGC patients. MGC and LEMPC patients showed similar clinicopathological features, except T stage and lymph node metastasis.

Conclusion: LEMPC can be thought of as a previous step of MGC. It is reasonable to consider LEMPC patients in the diagnostic criteria of MGC, and to adequately treat.

Mentions: Comparison of Recurrence rates with NMGC, MGC and LEMPC revealed no differences in DFS curves (P < 0.170) (Fig. 3). In multivariate analysis, prognostic factors for recurrence rate were T stage and N stage (Table 5).
