Docetaxel and oxaliplatin in the second-line treatment of platinum-sensitive recurrent ovarian cancer: a phase II study.
2007
ABSTRACT Background A prospective phase II study was conducted to evaluate the efficacy and toxicity of the combination docetaxel (Taxotere) (DTX) and oxaliplatin (OXA) in ovarian cancer patients recurring after a platinum-free interval (PFI) >12 months. Patients and methods DTX, 75 mg/m2, was administered by 60 min i.v. infusion, followed by OXA, 100 mg/m2, given by a 2 h i.v., on day 1 every 21 days. Results From October 2003 to June 2006, 43 ovarian cancer patients were enrolled. Median PFI was 26 months. All patients were available for response evaluation: 17 complete responses and 12 partial responses were registered, for an overall response rate of 67.4%. The median response duration …
Docetaxel plus prednisone in patients with metastatic hormone-refractory prostate cancer: An Italian clinical experience
2011
Aims and Background: We investigated the efficacy of docetaxel plus prednisone in Italian patients with metastatic hormone- refractory prostate cancer (mHRPC). Methods: Twenty four patients with mHRPC received docetaxel 75 mg/m2 every 3 weeks plus prednisone 5 mg twice daily for up to six cycles. The primary endpoint was efficacy measured by a reduction in serum prostate specific antigen (PSA) levels and measurable disease. Evaluation of toxicity, quality of life and reduction of pain were secondary endpoints. Results: PSA response was seen in 18 patients (75%). We observed a partial response in 2 patients (8.3%), stable disease in 10 patients (41.7%), and disease progression in 12 patients…
SNPs and taxane toxicity in breast cancer patients
2014
Aim: In order to identify genetic variants associated with taxanes toxicity, a panel with 47 SNPs in 20 genes involved in taxane pathways was designed. Patients & methods: Genomic DNA of 113 breast cancer patients was analyzed (70 taking docetaxel, 43 taking paclitaxel). Results: Two SNPs associated with docetaxel toxicity were identified: CYP3A4*1B with infusion-related reactions; and ERCC1 Gln504Lys with mucositis (p ≤ 0.01). Regarding paclitaxel toxicity: CYP2C8 HapC and CYP2C8 rs1934951 were associated with anemia; and ERCC1 Gln504Lys with neuropathy (p ≤ 0.01). Conclusion: Genes involved in DNA repair mechanisms and reactive oxygen species levels influence taxane toxicity in cance…
Abstract B09: Nintedanib inhibits tumor and vessel growth and leads to vascular normalization in A549-NSCLC-xenografts
2015
Abstract Angiogenesis plays a major role in the growth and progression of non-small-cell lung cancer (NSCLC). The triple angiokinase inhibitor nintedanib is a potent inhibitor of the receptor tyrosine kinases FGFR-1, 2, 3, PDGFR-α and β, VEGFR-1, 2, 3. and Flt-3. as well as of non-receptor tyrosine kinases like Src, Lyn and Lck by occupying the intracellular ATP-binding pocket. In the pivotal LUME-Lung 1 trial Nintedanib plus docetaxel has proven an overall survival benefit over docetaxel monotherapy in second-line treatment of non-small-cell lung cancer of adenocarcinoma. The aim of this study was to analyse treatment induced vascular normalization of nintedanib, bevacizumab and docetaxel …
Abstract 1423: Shikonin impairs the growth of docetaxel-resistant prostate cancer cells by necroptosis
2021
Abstract Introduction: Prostate carcinoma (PCa) is the most common malignancy in men. Androgen-targeted therapy and chemotherapy are currently the treatment of choice for advanced stages. Due to resistance towards these therapies, prognosis remains poor and new treatment options are urgently required. Shikonin (SHI) from Traditional Chinese Medicine (TCM) might be promising, since it induces anti-tumor effects in different tumor entities. However, data on PCa are few, and data on resistant PCa are not existent. Material and Methods: Parental (=sensitive) and docetaxel-resistant PCa cell lines, PC3, DU145, LNCaP, and 22Rv1 were exposed to SHI [0.1 - 1.5 μM] for 24, 48, or 72 hours. Untreated…
A randomized phase II study of estramustine phosphate versus estramustine phosphate plus etoposide in hormone refractory prostate cancer (HRPC)
2008
20632 Background: Docetaxel-based regimens represent the treatment of choice of HRPC. However, in some patients toxicity may be a concern and the quality of life may be compromised. The aim of this phase II randomized study is to investigate the efficacy and safety of low-dose chemotherapy regimen adopting a combination of EMP and VP16 in patients affected by HRPC. Methods: 54 HRPC patients were randomized between: arm A, daily oral standard dose EMP (10mg/kg) and arm B, low-dose EMP (3mg/kg) plus VP16 (25mg/mq) for 2 weeks followed by 2-weeks’rest. Systemic toxicity and hematologic exams were monitored every 2 weeks. Performance status, pain and analgesic use were evaluated according to WH…
Impact of Hypoxia-Related Tumor Acidosis on Cytotoxicity of Different Chemotherapeutic Drugs In Vitro and In Vivo
2014
Extracellular acidosis in tumors leads to an activation of the p-glycoprotein (Pgp) drug transporter. In the present study the cytotoxicity of different chemotherapeutic drugs and its dependence on the Pgp activity during acidosis were analyzed in vitro and in vivo. Treating R3327-AT1, Pgp-positive tumor cells at pH 7.4 with daunorubicin, cisplatin or docetaxel led to marked apoptosis induction and cell death. Under acidic (pH 6.6) conditions cytotoxicity of daunorubicin or docetaxel was significantly reduced whereas cisplatin-induced cell death was almost pH-independent. Inhibiting Pgp with verapamil reversed the acidosis-induced chemoresistance against daunorubicin and docetaxel. The Pgp …

2013
e17021 Background: This study investigates efficacy and toxicity of docetaxel added to cetuximab, cisplatin and 5-FU for patients with R/M SCCHN. We here report a planned second interim analysis to compare response rates between arms in order to decide on continuing to full accrual. Methods: Inclusion criteria were: stage III/IV R/M SCCHN and ECOG 0-1. Patients were randomized to arm A: cetuximab (standard dose) plus a maximum of 6 cycles of docetaxel (40 mg/m², day 1+8), cisplatin (40 mg/m², day 1+8) and 5-FU (2000 mg/m², day 1+8) or to arm B: cetuximab (standard dose), cisplatin (100 mg/m², day 1) and 5-FU (1000 mg/m², day 1-4). Treatment was administered until progression or intolerabil…

Peripheral olfactory function in rats after chemotherapeutic treatment with the anticancer drug docetaxel
2008
International audience; Clinical studies have documented that chemotherapeutic cancer treatment in humans is often associated with weight loss and decreased enjoyment of food. Beside taste, olfaction plays a role in the food intake regulation. We assessed whether hemotherapeutic cancer treatment compromises olfactory function in rats treated with docetaxel (Taxotere, TAX), an antineoplastic drug which disrupts the structures necessary for cell survival and division. Electroolfactogram responses (EOG) can indicate morpho-pathological changes in olfactory epithelium. Male rats received either a single, two or three intravenous injections (one per week) of an estimated 10% lethal dose (LD10) o…
