We have shown that the 16D10 antigen located on the mucin-like COOH-terminal domain of the feto-acinar pancreatic protein (FAPP) is expressed at the surface of human pancreatic tumor cell lines such as SOJ-6 cell line. Furthermore, an in vivo study indicates that targeting this cell-membrane glycopeptide by the use of the monoclonal antibody (mAb) 16D10 inhibits the growth of SOJ-6 xenografts in nude mice. To validate the potential use of the mAb16D10 in immune therapy, this study examined the expression of 16D10 antigens at the surface of human pancreatic adenocarcinomas versus control tissues.

Pancreatic ductal carcinomas are thought to arise from precursor ductal lesions called pancreatic intra-epithelial neoplasias or PanINs. We report the case of a woman suffering from idiopathic chronic pancreatitis associated with PanINs lesions who developed six years later an invasive ductal carcinoma. Immunohistochemistry for p53, HER-2/neu and genetic analysis of K-ras oncogene were performed at different stages of disease and revealed that the PanINs and the carcinoma did not express p53 and HER-2/neu gene products whereas a K-ras mutation was present at the carcinoma stage.

Background: Long-term results of the surgical treatment of stage I non-small cell lung cancer (NSCLC) are disappointing.

Methods: Univariate and multivariate analyses were conducted on 515 consecutive lung resections for stage I NSCLC performed from 1990 to 1999 and identified by reviewing a database into which data were entered prospectively. Tumors were staged as stages IA (n = 147) and IB (n = 348) according to the 1997 UICC (Union Internationale Contre le Cancer) pTNM classification.
