The Prognostic Significance of the Preoperative Full Blood Count after Resection of Colorectal Liver Metastases

Table 3

Univariate survival analysis of tumour characteristics as prognostic covariates in resected CRLM.

	Overall survival		Disease free survival
	Median survival (Months)	𝑃	Median survival (Months)	𝑃
Dukes stage
A + 𝐵^∗	45	.241	28	.135
C + 𝐷^∗	31		19
Unilobar versus bilobar	41	.143	30	.002
disease	31		17
Resection margin
Clear	41	.001	24	<.001
Not clear	12		8
Hepatic lymph nodes
Involved	42	.067	23	.809
Not involved	26		21

^∗Due to the small number of patients with Dukes 𝐴 and 𝐷 tumours (𝑛=7 and 𝑛=2, resp.), those with Dukes 𝐴 and 𝐵 were grouped together for analysis and survival times compared with Dukes 𝐶 and 𝐷.
