Clinical significance of CD44v mRNA detection by PCR in peripheral blood of patients with hepatocellular carcinoma

Table 2 Clinicopathological data of the patients who responded during follow-up

CD44v MRNA in blood	Followed up, n	Responders, n	DTC	PTC	TEPV	DTN
+	10	9	8	2	9	7
-	5	4	1	1	2	1
Total	15	13	9	3	11	8

Note: DTC: deficiency of tumor capsule; PTC: penetration of tumor capsule; TEPV: tumor embolus in portal vein observed by microscopy; DTN: daughter tumor nodules observed by microscopy. χ²_DTC = 5.7778, P < 0.025; χ²_PTC = 0.0164, P > 0.9; χ²_TEPV = 5.3182, P < 0.025; χ²_DTN = 4.9661, P < 0.05.
