Comparison of patients by family history with gastric and non-gastric cancer

Table 7 Distribution of anatomical sites of tumors in 256 probands

Tumor site	FGC (n = 112)		Non-FGC (n = 144)
	Male proband (n = 76)	Female proband (n = 36)	Male proband (n = 98)	Female proband (n = 46)
Upper	22	5	42	16
	27		58
Medium	20	7	27	15
	27		42
Lower	34	24	29	15
	58		44
χ2 , P value	χ2 = 10.69, P < 0.05

Difference of tumor sites between two male subgroups: χ² = 4.99, P > 0.05; two female subgroups: χ² = 9.67, P < 0.05.
