Table 4 Expression analysis of cellular inhibitor of apoptosis protein 1 and cellular inhibitor of apoptosis protein 2 in a panel of pancreatic cystic tumours.

Tumour histotype		cIAP1‐positive cases/total cases (site)	cIAP2‐positive cases/total cases (site)
IPMN	Adenoma	0/1	1/1 (C)

	Carcinoma	0/3	3/3 (C)
Mucinous cystadenoma		0/3	1/3 (C)
Serous cystadenoma		1/5 (C)	5/5 (C)

C, cytoplasmic expression; cIAP1, cellular inhibitor of apoptosis protein 1; cIAP2, cellular inhibitor of apoptosis protein 2; IPMN, intraductal papillary mucinous cystic neoplasm.
