Metastasis of primary gallbladder carcinoma in lymph node and liver

Table 1 Radical procedures performed in 45 patients with gallbladder carcinoma.

Type of resection	Patients (n)	Percent (%)	I	II	III	IV A	IV B
C	3	6.7	2	1
C+N	7	15.6	2	3	2
C+WR+N	8	17.8	1	2	2	1	2
C+S4aS5+N	6	13.3				4	2
C+S4aS5+BD+N	8	17.8				5	3
C+ERH+N	2	4.4				1	1
HPD+N	5	11.1				1	4
C+S4aS5+Other+N	6	13.3			1	2	3
Total	45	100	5	6	5	14	15

Abbreviations: C, cholecystectomy; N, lymphadenectomy; WR, wedge resection of the liver bed; S4aS5, liver resection of segments IV a and V; BD, resection of the bile duct; ERH, extended right hepatic resection; HPD, hepatopancreaticoduodenectomy; Other, other organ tissue resection.

Table 2 Comparison of depth of invasion of the tumor (T) and lymph node metastases (N).

Depth of tumor	No. of patients with lymph node metastasis
	N0	N1	N2	Para-aortic lymph node
T1 (n = 6)	5	1	0	0
T2 (n = 8)	6	1	1	1
T3 (n = 5)	1	2	2	0
T4 (n = 26)	4	11	11	3
Total (n = 45)	16	15	14	4

T and N were based on TNM staging of the American Joint Committee on Cancer (AJCC).
