Mucinous carcinoma is considered a distinct pathological entity. However, mucinous
tumours can be divided into a least two groups: mucinous A (or paucicellular) and mucinous
B (or hypercellular). Mucinous B cancers display histological features that significantly
overlap with those of neuroendocrine carcinomas. We investigate using genome-wide
oligonucleotide microarrays whether mucinous A, mucinous B and neuroendocrine
carcinomas are entities distinct from histological grade-and molecular subtype-matched …
