Is matrilsin expression a useful marker of submucosal invasion and lymph node metastasis in early stage signet ring cell carcinoma of the stomach?
Early SIG revealed less invasiveness than non-SIG in terms of clinicopathologic features and MMP-7 expression. Preoperative estimation of the MMP-7 expression might be useful as a predictor of submucosal invasion and lymph node metastasis in early SIG.
The publication rates of abstracts submitted to POSNA is high compared with those of other international orthopaedic associations. The mean publication rate for accepted abstracts and rejected abstracts has increased substantially from 45% and 38% in 1991 to 1994 to 58.9% and 45% in 2003 to 2005, respectively.
