Specimen	Subtype	CAM5.2	VIM	HBME-1	TM	CAL	CD44H	WT-1	CEA	Leu-M1	Ber-EP4	EMA	p53
Specimen: B, biopsy; P, postmortem.														Staining: 0, less than 10% of tumour cells stained; 1, 10–39% of tumour cells stained; 2, 40–79% of tumour cells stained; 3, 80–100% of tumour cells stained; C, cytoplasmic staining; M, membranous staining; N, nuclear staining.	VIM, anti-vimentin; TM, anti-thrombomodulin; CAL, anti-calretinin; CEA, anti-carcinoembryonic antigen; EMA, anti-epithelial membrane antigen.
