Introduction: Doxorubicin (DOX) and paclitaxel (PTX) are both widely used anticancer drugs with a broad spectrum of antitumor activity, commonly against breast, ovarian, and lung cancers. Currently, these drugs are commercially available in liposomal formulations for their use in chemotherapy. This study generally proposed coconut oil bodies (COB) obtained from Cocos nucifera L. as an alternative carrier for DOX and PTX rather than the currently used liposome. Objectives: This study aimed to compare standard liposome and coconut oil bodies as drug carriers in terms of their microencapsulation efficiencies, lipid profiles, in vitro drug release and stability, as well as their cholesterol levels. Methods: Coconut oil bodies (COB) were isolated and purified from Cocos nucifera L. by modified sucrose gradient method followed by microencapsulation of standard drugs (doxorubicin and paclitaxel) through selfassembly and freeze-thaw method. The two standard drugs were encapsulated using COB and standard liposome. Encapsulation efficiency of both materials were determined. Lipid profiles of both encapsulating materials were analyzed by Fourier-transform infrared spectroscopy, gas chromatography-flame ionization detector, and cholesterol level determination. In vitro drug release and pH stability of both encapsulated drugs were analyzed. Results: Doxorubicin (DOX) and paclitaxel (PTX) were successfully incorporated in COB. Lauric acid was mainly abundant in COB and was able to lower cholesterol levels (5 mg/dL). COB incorporated with DOX and PTX showed stability at acidic and neutral pH. Drug release profile showed a rapid outburst within 3 hours compared to liposome encapsulated DOX and PTX. Conclusion Our study showed the encouraging potentials of using COB as wall materials that will make them attractive candidates for the formulation of pharmaceuticals for optimized drug delivery of cancer chemotherapeutics DOX and PTX

BACKGROUND/AIMS: Metronomic (MET) chemotherapy is a treatment characterized by frequent infusion of low doses of chemotherapeutic agent without extended break. The aim of this study is to evaluate the efficacy of MET chemotherapy compared with transarterial chemoembolization (TACE) in patients with child B class advanced hepatocellular carcinoma (HCC). METHODS: Seventy-three patients with child B class advanced HCC were analyzed between April, 2007 and August, 2013 according to two treatment groups: (i) MET chemotherapy group (n=43, Epirubicin 35 mg/body surface area [BSA] every 4 weeks, and cisplatin 15 mg/BSA and 5-fluorouracil 50 mg/BSA weekly for 3 weeks) via an implantable port system with 1 week break. (ii) TACE group (n=30, Adriamycin 20-50 mg) every 4 weeks. Primary endpoint was overall survival (OS). RESULTS: The median survival times in the MET and TACE groups were 4.5 months and 3.1 months, respectively. The overall survival rate showed significantly better in the MET treatment group than in the TACE group (P=0.039). When the factors affecting patient OS were analyzed, MET chemotherapy (P=0.038, hazard ratio {HR} 0.538 [95% confidence interval {CI} 0.299-0.967]) was independently associated with OS. Larger maximal tumor size, extrahepatic metastasis and advanced stage also were significant factors for OS (P=0.009, HR 1.064 [95% CI 1.014-16.064]; P=0.014, HR 2.120 [95% CI 1.164-3.861]; P=0.019, HR 2.046 [95% CI 1.125-3.720], respectively). CONCLUSIONS: MET chemotherapy showed survival benefit than TACE in patients with child class B advanced HCC. Therefore, MET chemotherapy may be considered as a treatment option for advanced HCC with poor liver function.

PURPOSE: Breast cancer ranks as the second most frequent cancer in women in Korea, and the rate is gradually increasing. Compared to European countries and USA., the Korean breast cancer occurs at a younger age (mean age: 47) than in western countries (mean age: 60). We suppose that there is some biological differences between Korean and western breast cancer. This study was designed to determine the target chemotherapy agents for use on individual patients and define target patients for chemotherapy during the post-op period. Additionally, we desired to acquire primary data for further proteomic analysis of patients. METHODS: Twenty-one patients with breast cancer were entered in this study. Tumor specimens were taken and in formed consent was obtained for use of the samples in drug sensitivity testing. MTS[3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxy methoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt] assay was able to be preformed in 16 patients (success rate, 76.2 percent). We used four drugs including Adriamycin, Epirubicin, 5-FU, and Taxol. RESULTS: In the axillary lymph node negative group, 5-FU (56.62%) and Taxol (53.85%) were sensitive drugs. There were no sensitive drugs in the p53 over-expression group. In the wild p53 group, 5-FU was the only sensitive drug. 5-FU was sensitive in both the ER and PR positive groups. Taxol was sensitive in the c-erbB2 low expression group. CONCLUSION: We obtained the results for chemosensitivity of breast cancer of Korean women. 5-FU and Taxol were relatively sensitive drugs, however we believe further data should be collected and added to obtain complete chemosensitivity results.
