DLC-1 expression levels in breast cancer assessed by qRT- PCR are negatively associated with malignancy.

OBJECTIVE: The aim of this study was to explore the expression of DLC-l in breast carcinoma and any association with tumor metastasis. METHODS: 51 surgical specimens of human breast carcinoma, divided into high invasive and low invasive groups according to their clinicopathological features, 30 cases of adjacent normal tissue and 28 benign breast lesions were examined by qRT-PCR for expression of DLC-1. RESULTS: Expression level of DLC-1 in adjacent normal tissue and benign breast lesion specimens was higher than that in breast carcinoma (P<0.0001); the values in the high invasive group with synchronous metastases were also lower than in the low invasive group (P=0.0275). The correlation between DLC-1 expression level and tumor progression and metastasis of breast cancer was negative. CONCLUSION: As an anti-oncogene, DLC-1 could play an important part in breast carcinoma occurrence, progression, invasiveness and metastasis. Detecting the changes of the expression of DLC-1 in the breast carcinoma may contribute to earlier auxiliary diagnosis of invasiveness, metastasis and recrudescence.

Clinical significance of axin and ß-catenin protein expression in primary hepatocellular carcinomas.

The aim of the present research was to investigate clinicopathologic correlations of immunohistochemically- demonstrated axin (axis inhibition) and ß-catenin expression in primary hepatocellular carcinomas (HCCs), in comparison with paraneoplastic, cirrhotic and normal liver tissues. Variation in Axin expression across groups were significant (P < 0.01), correlating with alpha fetoprotein (AFP), HBsAg, cancer plugs in the portal vein, and clinical stage of HCCs(P < 0.05); however, there were no links with sex, age, and tumour size (P > 0.05). Differences in cell membrane ß-catenin expression were also statistically significant (P < 0.01), again correlated with AFP, HBsAg, cancer plugs in the portal vein, and clinical stage in HCCs (P < 0.05) but not with sex, age, and tumour size (P > 0.05). Axin expression levels in tissues with reduced membrane ß-catenin were low (P < 0.05), also being low with nuclear ß-catenin expression (P < 0.05). Axin and ß-catenin may play an important role in the genesis and progression of HCC via the Wnt signal transmission pathway. Simultaneous determination of axin, ß-catenin, AFP, and HBsAg may be useful for early diagnosis, and metastatic and clinical staging of HCCs.

[Clinicel study on treatment of advanced primary liver cancer by Yanshu injection combining with chemotherapy].

OBJECTIVE: To study the effects of Yanshu injection on the combined treatment in the advanced primary liver cancer. METHOD: Eighty-five cases of advanced primary liver cancer were treated with Yanshu injection combining with chemotherapy or only chemotherapy. The curative effects, pain genesic rate, one year survival rate, survival quality of life and cell immune functions were observed. RESULT: The remission rate and one year survival rate of the trial group were 60.5% and 51.2%, respectively, and were significantly higher than those (45.2% and 40.5%) of the control group (P < 0.05). The pain relief rate of the trial group was significantly higher than that of the control group (P < 0.05). The improvement of the quality of life was higher than that of the contral group (P < 0.01). The ability of the T-cell subgroup and NK-cell of the trail group were significantly difference between pre-and post-treatment (P < 0.01 or 0.05); however, that of the control group was no obviously change. CONCLUSION: Yanshu injection combination with chemotherapy can raise the curative effect, one year survival rate and cellular immune function, reduce pain genesic rate and toxicity of chemotherapy, and improve the quality of life of the patients with advanced primary liver cancer, which is worthy to be recommended for clinical application.
