Introduction: Stromal Immune Contexture (SIC) helps predict prognosis in solid Tumors (T) but has been poorly investigated in gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs). We tested whether GEP-NENs profiling for adaptive immunity-related SIC markers, as well as inflammatory (COX2),EMT [Beta-catenin (B-cat)] and oncogenic pathway signaling (pS6) markers,could improve Ki67 and/or MO-based prediction of OS and DFS.

Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NETs) comprise a heterogeneous group of neoplasm with different histological patterns and biological behavior. Only limited information is available on immunohistochemical prognostic factors of disease. Alterations in the cell-cell adhesion system are closely associated with cell invasion and metastasis in many malignancies, including those of endocrine origin. Abnormal expression of E-cadherin and beta-catenin has been reported to play an important role in these processes. Caveolin-1 has recently been identified as a tumor metastasis modifier factor, which might increase the cell metastasis potential through the interaction with E-cadherin. However, the role of caveolin-1 in GEP NETs cell invasion remains unknown.
