Phase I pharmacokinetic and pharmacodynamic study of the prenyl transferase inhibitor AZD3409 in patients with advanced cancer.

AZD3409 is an orally active double prodrug that was developed as a novel dual prenyltransferase inhibitor. The formation of the active metabolite AZD3409 acid is mediated by esterases in plasma and cells. The aim of this phase I study was to determine the maximum tolerated dose, toxicities, pharmacokinetics and pharmacodynamics of AZD3409.

Comprehensive side-effect profile of anastrozole and tamoxifen as adjuvant treatment for early-stage breast cancer: long-term safety analysis of the ATAC trial.

Background: The Arimidex (anastrozole), Tamoxifen, Alone or in Combination (ATAC) trial was designed to compare the efficacy and safety of anastrozole with tamoxifen as adjuvant treatment for postmenopausal women with early-stage breast cancer. After an extended follow-up beyond the 5 years of treatment, we aimed to assess the safety, tolerability, and risk-benefit indices of these compounds.

Methods: We analysed postmenopausal women (mean age 64 years [SD 9]) with localised breast cancer randomly assigned to anastrozole (n=3125) or tamoxifen (n=3116).

Results of the ATAC (Arimidex, Tamoxifen, Alone or in Combination) trial after completion of 5 years' adjuvant treatment for breast cancer.

The standard adjuvant endocrine treatment for postmenopausal women with hormone-receptor-positive localised breast cancer is 5 years of tamoxifen, but recurrences and side-effects restrict its usefulness. The aromatase inhibitor anastrozole was compared with tamoxifen for 5 years in 9366 postmenopausal women with localised breast cancer. After a median follow-up of 68 months, anastrozole significantly prolonged disease-free survival (575 events with anastrozole vs 651 with tamoxifen, hazard ratio 0.

[Platinum compounds in cancer therapy--past, present, and future].

Platinum cytotoxics play an important role globally in the management of solid tumours. Cisplatin sets the standard for efficacy in both regions with careful administration to reduce nephrotoxicity. Carboplatin is associated with neurotoxicity, but has become the leading product in the US due largely to the easier to manage toxicity profile.

Bleomycin, methotrexate, and CCNU in locally advanced or recurrent, inoperable, squamous-cell carcinoma of the vulva: an EORTC Gynaecological Cancer Cooperative Group Study. European Organization for Research and Treatment of Cancer.

Objective: To investigate tumor response rate and treatment toxicity of a modified combination chemotherapy consisting of bleomycin (B), methotrexate (M), and CCNU (C) for patients with locally advanced, squamous-cell carcinoma of the vulva (not amenable to resection by standard radical vulvectomy) or recurrent disease (after incomplete resection). Tumor resectability was reassessed in patients who had responded to chemotherapy.

Methods: The regimen consisted of bleomycin 5 mg intramuscular (im) days 1-5, CCNU 40 mg per os (po) days 5-7, and methotrexate 15 mg po days 1 and 4 during the first week.
