The Clinicopathological Features and Long-Term Survival Outcomes of Mucinous Gastric Carcinoma: a Consecutive Series of 244 Cases from a Single Institute

Mucinous gastric carcinoma (MGC) is a rare kind of malignancy with unclear prognosis. This study aims to assess the clinicopathological features and prognosis of MGC. We retrospectively analyzed a consecutive series of 244 MGC patients who underwent radical gastrectomy with D2 lymphadenectomy, and compared the data with 260 gastric signet ring cell carcinoma (SRC) patients. The univariate survival analysis showed that the surgical types, diameter of the primary tumor, the Borrmann type, pathological depth of tumor invasion (pT), pathological number of metastatic lymph node (pN), pathological tumor lymph metastasis (pTNM), and vascular invasion were all significant predictors of survival (all P
