Methods: The expression of the LRP gene encoding LRP and mRNA LRP was detected in tissues from 54 untreated patients with HCC, adjacent tissues from 24 patients with HCC and archival paraffin-embedded tissues from 12 patients with posthepatitic cirrhosis. The relationship between the LRP gene expression and the change of AFP level was analyzed in the 24 postoperative HCC patients whose AFP was measured after 2 weeks. All of the HCC patients were followed up. Results: The percentage of positive expression of LRP and mRNA LRP in the 3 tissues was 61.1%, 33.3%, 16.7%, and 75.9%, 37.5%, 33.3% respectively. There was significant difference between the untreated HCC tissue and other tissues (P<0.05). No difference existed between the LRP gene expression and clinicopathologic findings, age, sex, and tumor size (P>0.05), but the expression was related to the degree of differentiation of HCC (P<0.05). The effective rate of AFP in the LRP gene positive expression group or in postoperative chemotherapeutic patients was very lower than that in the negative group (P<0.05). Although the mean survival time of postoperative HCC patients in negative LRP gene expression group was longer than that of positive group, there was no difference between them (P<0.05). Conclusion: LRP gene expression is related to MDR of HCC and initiates the intrinsic MDR. Detection of LRP gene expression is of great guiding significance in accessing chemotherapeutic resistance of HCC. As an index to chemotherapy of HCC, detection of LRP expression provides evidence for making individual chemotherapeutic treatment,and reversing MDR in HCC. Although LRP gene expression correlates with the tumor differential degree (P<0.05), it perhaps does not relate with the prognosis of HCC patients.展开更多
