Genomic Profile of Appendiceal Goblet Cell Carcinoid Is Distinct Compared to Appendiceal Neuroendocrine Tumor and Conventional Adenocarcinoma

Goblet cell carcinoid (GCC) is a rare appendiceal tumor with unique morphologic features that shows glandular and neuroendocrine differentiation on immunohistochemistry. An additional component of adenocarcinoma (AC) can be present (GCC-AC). Both GCC and GCC-AC are staged and treated like AC. The histogenesis and genetic alterations underlying GCC and GCC-AC are unclear. Capture-based next-generation DNA sequencing targeting 479 cancer genes was performed on 19 appendiceal tumors: 4 GCC, 9 GCC-AC, 3 neuroendocrine tumors (NET), and 3AC (2 conventional, 1 mucinous).
