Filter by:Androgen deprivation therapy (ADT) by surgical castration or administration of LHRH agonists or antagonists is the gold-standard systemic treatment of Prostate Cancer. The efficacy, severity and frequency of side effects of ADT vary from a patient to another. The exact cause of this variability is not known, however certain genetic polymorphisms affecting enzymes implicated in the synthesis and metabolism of sex-steroids seem to be involved in these processes. To perform a longitudinal study to evaluate the prevalence of various genetic polymorphisms affecting genes in the sex-steroid synthesis and metabolism pathway (CYP1A1, CYP1B1, CYP19A1, 17HSD, HSD3B1, AR, ESR1, ESRRG, IL6, TNF-alpha) in men with Prostate Cancer receiving ADT and the possible association between polymorphisms and frequency and severity of side-effects of ADT.
This is to prospectively investigate whether the chemopreventive agent, MCS, may favorably alter biomarker expression, whether serum carotenoids levels are associated with biomarkers levels, and whether the alterations of biomarker expression may reflect the cancer risk as shown by cancer incidence at the end of the clinical trial.
The SPARK trial is testing the use of Kilovoltage Intrafraction Monitoring in prostate cancer patients being treated with Stereotactic Prostate Adaptive Radiotherapy. The researchers expect this trial to result in better targeted prostate cancer patient outcomes with lower toxicity. The potential application of Kilovoltage Intrafraction Monitoring to other tumour sites will pave the way for additional trials with Australasian radiation oncology leading the world.
This trial examines the feasibility and toxicity of focal brachytherapy in patients with low-risk prostate cancer.
To evaluate the use of the CAMbridge PROstate Biopsy devicE (CAMPROBE) as a method of undertaking prostate biopsy as part of their clinical management.
Objectives: Primary: Comparison of proportion of patient achieving continence between the four arms at 6 months. Secondary: - Comparison of time to achieve continence between the four arms. - Comparison of urinary symptoms and quality of life improvement between the four arms. - Assessment of adverse events in Duloxetine arms. Primary outcome/ time frame: Proportion of patient achieving continence at 6 months. Continence is defined as "using no pad"or "only security pad". Secondary outcome: - time to achieve continence - Quality of life tested in relation to incontinence according to Visual Analog Scale (VAS) and King's Health Questionnaire (KQH). - Urinary symptoms measured with International Prostate Symptom Score (IPSS). No. of subjects entered: 300 patients informed and included, 240 patients will be randomized. Statistical methods - Proportion of patients who achieve continence and time to achieve continence will be compared between the four arms. - Comparison of quality of life outcomes between the four arms - Comparison of clinical variables that can affect the primary/secondary outcome - univariate and multivariate analysis (ITT).
The purpose of this study is to assess the efficacy of intensified intravenous Melphalan in combination with a transplant of patients' own blood stem cells for a maximum of three cycles. In a recently completed small Phase I study looking at the use of higher doses of intravenous Melphalan with the combination of lenograstim (a drug that stimulates bone marrow to produce white blood cells helping to fight infection) and patients' own blood infusion over 4 cycles of treatment has proved encouraging. The results of this study showed rapid improvement in pain and a fall in circulating tumour cells within two weeks of starting Melphalan. However, slow platelet recovery after the fourth cycle meant longer periods of platelet transfusion. For this trial we intend to assess the efficacy of an intensified intravenous Melphalan with transplant of patients' own blood stem cells over a shorter time period. This study will involve approximately 39 patients over a 3 year period.
High-dose rate brachytherapy (HDR-BT) is an advanced technology theorized to be more advantageous than LDR-BT and External Beam Radiotherapy (EBRT), to the patient himself, and in terms of resource allocation. Studies of HDR-BT monotherapy have encouraging results in terms of biochemical control, patient survival and toxicity, but there are still certain limitations that preclude recommending HDR-BT monotherapy outside the setting of a clinical trial. The primary endpoint of this study is to evaluate the safety, tolerance and impact on quality of life (QoL) of the BT-HDR 19Gy administered in single fraction in patients with low and intermediate risk prostate cancer. Secondary endpoint is to measure the efficacy, in terms of cancer control and satisfaction of the patients undergoing the experimental treatment. Forty nine patients will be recruited for the experimental procedure Quality of Life, tolerance, gastrointestinal and genitourinary toxicity will be assessed using standardized procedures and scales. Patient satisfaction with the procedure will be appraised using five-category predetermined Likert scale questions. Two different types of intermediate analyses will be performed: with 15 and 30 recruited patients. The experimental treatment tested in this study is very innovative. Since prostate cancer is the most frequent cancer in men in Spain, this trial results are very likely to have a major impact on the standard therapy for prostate cancer in our National Health Service, allowing for a higher number of Hospitals within our country and other countries starting protocols of HDR BT 19Gy in single fraction.
The purpose of this study is to find out the effects (good and bad) of highly focused radiation on you and your prostate cancer. The purpose of this evaluation is to see if this treatment causes fewer side effects that other standard treatment approaches, and to evaluate the effect of this treatment on your prostate tumor and your quality of life over time.
The investigators will assess the feasibility of intraoperative use of C-arm cone-beam CT imaging for intraoperative dosimetric evaluation in prostate low-dose-rate (LDR) brachytherapy. Patients recruited are those who will receive standard LDR brachytherapy for prostate cancer treatment. Consenting patients will undergo additional 3D C-arm cone-beam CT imaging (3D C-arm) and motorized trans-rectal ultrasound (TRUS). Volumetric and dosimetric measures will be compared to those using the standard Day-0 CT images. The investigators hope that the intraoperative 3D C-arm provides quality assurance measures sufficient to eliminate the need for Day-0 CT LDR brachytherapy and provide the opportunity for intraoperative modification of seed delivery plan.
