[Study of expression of CD138 and heparinase in hepatocellular carcinoma by tissue microarray].

Abstract

OBJECTIVE:

To study the expression of CD138 and heparinase in hepatocellular carcinoma (HCC) and its relationship with tumor development, progression, metastasis and recurrence.

METHODS:

Tissue microarray and immunohistochemical study (EnVision method) for CD138 and heparinase was performed on tissue microarray which consisted of 197 cases of HCC, including adjacent non-neoplastic liver tissues, and 66 cases of HCC metastases.

RESULTS:

The rates of CD138 expression in HCC and adjacent non-neoplastic liver tissues were 48.7% (96/197) and 65.0% (128/197, P < 0.05) respectively. In early-stage and late-stage tumors, the expression rates were 61.7% (29/47) and 44.7% (67/150, P < 0.05) respectively. The rate in patients with metastasis was 33.3% (22/66), as compared with 53.6% (45/84, P < 0.05) in patients without metastasis. In patients with tumor recurrence occurring within or after 1 post-operative year, the expression rates were 23.3% (7/30) and 61.1% (11/18, P < 0.05) respectively. On the other hand, the rates of expression of heparinase in HCC and adjacent non-neoplastic liver tissues were 35.5% (70/197) and 12.7% (25/197, P < 0.05) respectively. In early-stage and late-stage tumors, the expression rates were 29.8% (14/47) and 37.3% (56/150, P > 0.05) respectively. The rate in patients with metastasis was 48.5% (32/66), as compared with 28.6% (24/84, P < 0.05) in patients without metastasis. In patients with tumor recurrence occurring within or after 1 post-operative year, the expression rates were 50.0% (15/30) and 44.4% (8/18, P > 0.05) respectively. In the 66 cases of metastatic HCC studied, the expression rate of CD138 was lower in the heparinase-positive subgroup (P < 0.05).

CONCLUSIONS:

Loss of CD138 expression is related to HCC development, progression, metastasis and recurrence. Overexpression of heparinase, when coupled with loss of CD138 expression, may take part in tumor metastasis of HCC.
