Table 2 The expression of PP60^c-src in CA of different histo logical types

Lesion	Case	Staining intensity			Positive rate (%)
		-(%)	+(%)	+ + - + + +(%)
Papillary	8	2(25.0)	6(75.0)	0(0)	6(75.0)
Tubular	22	4(18.2)	4(18.2)	14(63.6)b	18(81.8)a
Poorly differentiated	20	10(50.0)	10(50.0)	0(0)	10(50.0)

Total	56	16(28.6)	20(35.7)	20(35.7)	40(71.4)

^aP < 0.05,in comparison of the positive rat es of tubular and mucous adenocarcinomas vs those of papillary and poorly differentiated adenocarcinomas ( χ² = 8.11);

^bP < 0.01,in comparison of the positive rates of tubular and mucous adenocarcinomas vs those of papillary and poorly differentiated adenocarcinomas ( χ² = 27.56).
