In this study, we investigated two formulations of chitosan-Pluronic P123 with different folate ligand designation for targeted delivery of Paclitaxel (PTX), in which folic acid (FA) was directly conjugated to chitosan (FA-Cs-P123) or substituted onto P123 (Cs-P123-FA). The results showed that the FA content of Cs-P123-FA was determined at 0.71 wt/wt% which was significantly higher than that of FA-Cs-P123 (0.31 wt/wt%). Two copolymers were low critical gel concentrations (CGC). FA-Cs-P123 and Cs-P123-FA nanogels performed high PTX encapsulation efficiency reaching 95...

Background and Aims: Ovarian carcinoma (OC) is one of the most lethal malignant tumors with a high reoccurrence and chemoresistance. The key mechanism relationship with chemoresistance in ovarian carcinoma is still unclear. The existence of cancer stem cells involves in chemoresistance and reoccurrence in OC. The objective of this study was to investigate the expression, suppression of malignant properties and reversal of paclitaxel resistance inhibiting RNA-binding protein Musashi-1 with siRNA in ovarian cancer cells...

BACKGROUND: The aim of the present trial was to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of liposomal cisplatin (lipoplatin) using nephrotoxicity, gastrointestinal toxicity and myelotoxicity as the main adverse reactions. PATIENTS AND METHODS: Lipoplatin, a liposomal formulation of cisplatin was first tested as monotherapy starting at a dose of 125 mg/m(2) and escalating up to 350 mg/m(2). Lipoplatin was then escalated in combination with paclitacel starting at a dose of 100 mg/m(2) escalating up to 250 mg/m(2) for the former and 100 mg/m(2) escalating up to 175 mg/m(2) for the latter...

BACKGROUND: Cyclooxygenase (COX-2) overexpression is seen in many malignancies including lung cancer. Recent pre-clinical studies have shown that selective COX-2 inhibitors have demonstrated promising results when used with chemotherapy. Based on these observations, we assessed the efficacy and tolerability of the combination chemotherapy consisting of carboplatin and paclitaxel with meloxicam, a selective COX-2 inhibitor. METHODS: Forty-four patients with stage IIIB or IV non-small cell lung cancer (NSCLC), Eastern Cooperative Oncology Group performance status (PS) 0 or 1, who had adequate organ function, were eligible...

Human epidermal growth factor receptor (HER 2) is amplified in 25 to 30% of breast cancer patients and those whose tumors demonstrate HER 2 gene amplification and protein overexpression have an inferior prognosis manifested by shorter disease-free and overall survival. Trastuzumab, the humanized murine anti-HER 2 monoclonal antibody, inhibits tumor growth when used alone and has synergistic and additive effects when used with chemotherapeutic agents (paclitacel-doxorrubicine). At the present time, the accurate diagnostic assessment of HER 2 is essential for appropriate application of the humanized anti HER 2 monoclonal antibody, trastuzumab, for the treatment of patients with metastatic breast cancer...

In initial studies the dose-limiting toxicity of paclitaxel monotherapy was leukopenia. In these studies, paclitaxel was administered over 24 hrs. The aim of the present phase II clinical trial was to investigate the efficacy and the hematological toxicity of a 3 hr paclitaxel infusion in previously untreated patients with NSCLC. Patients received 4 cycles of a chemotherapy consisting of paclitaxel 225 mg/m2 every three weeks. 30 patients (7 female, 23 male) were enrolled in the study. The characteristics of the patients are as follows: age 64 (47-75 yrs); histology: 19 x squamous cell carcinoma, 11 x adenocarcinoma: 4 x IIIB, 26 x IV; performance status 80 (70-90)...

Platinum based chemotherapy is the cornerstone of treatment in advanced ovarian carcinoma. Paclitaxel, an unique antimicrotubule agent has shown significant clinical activity in cisplatin-resistant tumours, indicating a lack of cross-resistance. To compare the in vitro sensitivity of ovarian carcinoma to cisplatin and paclitaxel, we tested 7 ovarian carcinoma cell lines with the 96-well plate clonogenic assay. Chemosensitivity was expressed as the IC50 value i.e. the drug concentration causing 50% inhibition of clonogenic survival...
