BACKGROUND: Chemoembolization with doxorubucin-eluting beads (DEB) has been used to treat hepatocellular carcinoma (HCC) since 2007. This study compared the efifcacy and sur-vival between transarterial chemoembolization (TACE) with DEB and conventional approach (cTACE) in HCC treatment. METHODS: This retrospective case-control study compared the overall survival and tumor response of HCC patients to cTACE (n=190) and DEB (n=143) by the reassessment of com-puted tomography and serum alpha-fetoprotein (AFP). Mul-tivariate analysis was used to determine the factors affecting tumor response. RESULTS: The median post-treatment to pre-treatment AFP level was 0.8 for a DEB session (n=258) and 1.0 for a cTACE session (n=452), showing a signiifcantly greater decrease in AFP after DEB (Pchieved objective response (complete and partial) compared with those in the cTACE group (Pchieving at least one objective tumor response in a patient when compared to cTACE (P80 months after the ifrst TACE session in the DEB group. CONCLUSION: DEB is a safe alternative to cTACE in HCC pa-tients with better therapeutic efifcacy.

Objective:Although the utility of immunohistochemistry(IHC)for assessing mismatch repair(MMR)protein expression has been demonstrated in solid tumors including primary prostate cancer(PCa),its utility has not been assessed in castration-resistant PCa(CRPC).Methods:Tissue microarrays were constructed from 127 radical prostatectomies and 155 CRPC metastases from 50 ***(MLH1,MSH2,MSH6,and PMS2)expression was assessed by IHC and gene expression *** between MMR protein expression in PCa and CRPC and biochemical recurrence(BCR)or time from diagnosis to death respectively were ***:There was no correlation between levels of MMR protein and *** of MSH2 and MSH6 was the most pronounced at 15%and 22%in PCa and 17.8%and 16%in CRPC patients,***2 and MSH6 protein were absent in 9.4%and 8%of PCa and CRPC *** of individual MMR proteins did not correlate with BCR or time from diagnosis to *** absent MSH2/MSH6 in CRPC was associated with shorter time to death(pZ0.0006).Loss of MSH2 was verified at the gene expression *** finding correlated with microsatellite instability previously reported in this CRPC cohort.
