PSCA and Oct-4 Expression in the Benign and Malignant Lesions of Gallbladder: Implication for Carcinogenesis, Progression, and Prognosis of Gallbladder Adenocarcinoma

Table 1

PSCA and Oct-4 expression in benign and malignant lesions of gallbladder.

Tissue types	Total no.	PSCA			Oct-4
		Pos. nos. (%)	𝜒^2	^∗𝑃	Pos. nos. (%)	𝜒^2	^∗𝑃
GBC	108	59 (54.6)			60 (55.6)
PT tissue	46	9 (19.6)	16.08	<0.01	10 (21.7)	14.89	<0.01
G. polyp	15	2 (13.3)	8.99	<0.01	2 (13.3)	9.39	<0.01
C. cholecystitis	35	5 (14.3)	17.40	<0.01	5 (14.3)	18.16	<0.01

∗Compared with gallbladder adenocarcinoma (GBC). PT tissue: peritumoral tissue; G. polyp: gallbladder polyp; C. cholecystitis: chronic cholecystitis; Pos. nos. positive numbers.
