MATERIALS AND METHODS: A retrospective cohort study of patients undergoing either treatment was carried out from January 2009 to December 2014. Tumour response to the procedures was evaluated according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Kaplan-Meier analysis was used to assess and compare the overall survival in the two groups.
RESULTS: A total of 79 patients were analysed (34 had c-TACE, 45 had DEB-TACE) with a median follow-up of 11.8 months. A total of 20 patients in the c-TACE group (80%) and 12 patients in the DEB-TACE group (44%) died during the follow up period. The median survival durations in the c-TACE and DEB-TACE groups were 4.9 ± 3.2 months and 8.3 ± 2.0 months respectively (p=0.008). There was no statistically significant difference noted among the two groups with respect to mRECIST criteria.
CONCLUSIONS: DEB-TACE demonstrated a significant improvement in overall survival rates for patients with unresectable HCC when compared to c-TACE. It is a safe and promising approach and should potentially be considered as a standard of care in the management of unresectable HCC.
OBJECTIVE: The main objective of this study is to determine the potential anti-proliferative effect of KGM on cancer and normal human liver cell lines, HepG2 and WRL68, respectively.
METHOD: HepG2 and WRL68 cells were treated with KGM, D-mannose, KGM-D-mannose and 5-fluorouracil. The morphological changes in those treated cells were observed. Cytotoxic effect of the treatments on cell viability and proliferation, and apoptosis genes expression were assessed by cytotoxicity assay, flow cytometry and RT-PCR analyses.
RESULTS: The results show that KGM treatment resulted in reduced viability of HepG2 cells significantly, in line with the apoptosis-like morphological changes. Up-regulation of BAX and down-regulation of BCL2 genes as reflected by high Bax to Bcl 2 ratio suggests that the inhibitory effect of KGM on HepG2 cells most likely via Bcl2/Bax protein pathway. Despite the effectiveness of standard drug 5-FU in suppressing the viability and proliferation of HepG2 cells, it however, exhibited no selective inhibition of cancer cells as compared to KGM.
CONCLUSION: Current findings suggested that KGM is a potential anti-cancer compound/drug entity, which could be an alternative preventive agent against liver cancer.
METHODS: The cytotoxicity activity was measured using the MTS assay. The mode of cell death determined by the apoptosis study, DNA fragmentation analysis done by using the TUNEL system. The pathway study or mechanism of apoptosis observed by study caspases 8, 9, 3/7 Glo-caspases method.
RESULTS: In this study, the methanol extracts prepared from leaf Xylocarpus mouccensis leaf produced cytotoxicity effect with IC50 (72hr) < 30µg/ml. The IC50 value at 72 hours exerted by diethyl ether extract of Xylocarpus moluccensis leaf was 0.22 µg/ml, which was more cytotoxic than to that of crude methanol extract. The results obtained by the colorimetric TUNEL system suggest that methanol crude extract of Xylocarpus moluccensis (leaf), diethyl ether extract of Xylocarpus moluccensis (leaf) and methanol extract of Xylocarpus granatum (bark) induced DNA fragmentation in the HepG2 cell line. Besides, the caspase-Glo assay demonstrated that diethyl ether leaf extract of Xylocarpus moluccensis triggered apoptotic cell death via activation of caspases -8, and -3/7 However, no visible activation was noticed for caspase -9. Furthermore, TLC indicates the presence of potential metabolites in an extract of Xylocarpus moluccensis.
CONCLUSION: Thus, the present study suggests the remarkable potential of active metabolites in the extract of Xylocarpus moluccensis as a future therapeutic agent for the treatment of cancer.
