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

Table 6 Distribution of tumor histological types (converting the WHO to the Lauren classification) of 256 probands

Lauren classification	WHO classification	FGC (n = 112)		Non-FGC (n = 144)
		Male proband (n = 76)	Female proband (n = 36)	Male proband (n = 98)	Female proband (n = 46)
Intestinal type	Well	3		2
	Moderately	19	6	39	12
	Mucinous	5	3	5	3
	Total	27	9	46	15
Diffuse type	Poorly	44	24	39	25
	Signet-ring cell	3	2	11	6
	Undifferentiated	2	1	2
	Total	49	27	52	31

Well: Well differentiated adenocarcinoma; Undifferentiated: Undifferentiated carcinoma; No statistical differences of histological types were found between any two subgroups, although ratio of intestinal to diffuse types was lower in FGC than in Non-FGC (36/76 = 0.47 from FGC against 61/83 = 0.73 from non-FGC).
