Effective oral combination metronomic chemotherapy with low toxicity for the management of castration-resistant prostate cancer.

Prostate cancer (PC) was previously believed to be a chemoresistant disease. In recent years taxane-based chemotherapy has been shown to prolong survival in patients with castration-resistant prostate cancer (CRPC). It remains to be shown, however, which type of chemotherapy provides the most beneficial effect with the least amount of side effects.

Calculated and simulated effects of heterogeneous dose distributions in radiotherapy using the dose volume inhomogeneity corrected biological equivalent dose formula with special reference to prostate cancer.

The aim of this study was to evaluate and estimate the impact on the biological effective dose (BED) of irradiation delivered to a tumour during high dose rate brachytherapy with a heterogeneous dose distribution in the target volume. The calculation of BED in combination with the critical-voxel model and the LQ (linear quadratic) model was used to evaluate the effect of different combinations of heterogeneous dose distribution. The model is called the dose volume inhomogeneity corrected BED (DVIC-BED).

Palliation of bone pain in prostate cancer using chemotherapy and strontium-89. A randomized phase II study.

Strontium-89 is an established alternative for the alleviation of bone pain in prostate cancer. There are few data evaluating the effect on pain of palliative chemotherapy. The aim of this randomized phase II study was to assess and compare the analgesic efficacy of strontium-89 and chemotherapy (FEM=5-FU, epirubicin, and mitomycin C) in 35 patients with disseminated, hormone-refractory prostate cancer suffering from persisting bone pain despite analgesic treatment.

Postoperative radiotherapy after prostatectomy--a review.

Purpose: The management of prostate adenocarcinomas using postoperative irradiation is a controversial question. The purpose of this study was to review the literature on the subject.

Material And Methods: A total of 417 articles dealing with postoperative radiotherapy after radical prostatectomy in English literature (1990-2002) were reviewed in aspects of effect on survival, time of irradiation, risk factors, dose and technique and side effects.

Development of dextran derivatives with cytotoxic effects in human urinary bladder cancer cell lines.

Background: In a previous study we reported on a new approach describing intravesical instillation of charged dextran in patients with superficial bladder carcinoma. The cationic derivative showed a strong tumor-selective accumulation. To develop this approach, the present study investigates the cytotoxic effect of cationic dextran derivatives on two urinary bladder cancer cell lines (J82 and 5637).
