Background: The aim of the present study was to analyze whether Homer1 is a potential prognostic marker for intrahepatic cholangiocarcinoma (ICC). Materials and Methods: The expression of Homer1 in ICC tissue was detected with immunohistochemistry and levels of protein in ICC and paratumor tissues were evaluated by Western blotting. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance. Results: Homer1 expression was high in 67.4% (58/86) of ICC samples, and there was significant difference between ICC and adjacent noncancerous tissues (p<0.001); high expression was associated with poor histologic differentiation (p=0.019), TNM stage (p=0.014), lymph node metastasis (p=0.040), and lymphatic invasion (p=0.025). On Kaplan-Meier analysis, a comparison of survival curves of low versus high expressors of Homer1 revealed a highly significant difference in OS (p=0.001) and DFS (p=0.006), indicating that high expression of Homer1 was linked with a worse prognosis. Multivariate analyses showed that Homer1 expression was an independent risk factor predicting overall survival[Hazard ratio(HR), 7.52; 95% confidence interval (CI), 2.63-21.47; p=0.002] and disease-free survival (HR, 11.56; 95%CI, 5.17-25.96; p<0.001) in ICC. Conclusions: Homer1 promotes lymphatic invasion and associates with lymph node metastasis and poor prognosis of ICC. The current study shows that Homer1 may be an independent prognostic factor for ICC patients after curative resection, and it provides an important basis for screening/treating high-risk patients.

Aim: To investigate whether XRCC1 and ADPRT polymorphisms might be associated with outcomes of breast cancer. Methods: A prospective study was conducted with a total of 335 breast cancer patients undergoing chemotherapy consecutively collected from Jan. 2005 to Jan. 2008. Genotyping of XRCC1 and ADPRT polymorphisms was conducted by PCR-RFLP assay. Results: All 335 patients were followed up until death or the end of Jan. 2012, with a median follow-up period of 38.8 (2-64) months. It was shown that the variant genotype of XRCC1 399Gln/Gln was strongly significantly associated with a decreased risk of death from breast cancer, with an HR (95% CI) of 0.52 (0.28-0.91). Similarly, individuals carrying the ADPRT 762Ala/Ala demonstrated longer survival compared to ADPRT 762 Val/Val, with an HR (95% CI) of 0.58 (0.31-0.97). Individuals with combination genotypes of XRCC1 399Gln allele and ADPRT 762Ala/Ala presented with a longer survival, the HR (95% CI) being 0.56 (0.32-0.97). Conclusion: We found a significant association between XRCC1399Gln/Gln and ADPRT 762Ala/Ala polymorphisms and clinical outcomes. These two genotypes could be used as a surrogate markers of clinical outcome in glioma cases receiving chemotherapy.
