Filter by:The main purpose of this study is to find out whether adding radiation therapy to the standard treatment of chemotherapy for prostate cancer is tolerated well and is more effective than the standard treatment of chemotherapy alone
RATIONALE: Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ixabepilone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Ixabepilone may also make tumor cells more sensitive to radiation therapy. Giving radiation therapy with chemotherapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase I/II trial is studying the side effects and best dose of ixabepilone when given together with radiation therapy to see how well it works in treating patients with high-risk stage III prostate cancer after surgery.
Patient anatomy and position during the course of radiation therapy can vary from those used for treatment planning; a function of patient movement, uncertainty in positioning system, and organ motion. Traditionally, treatment margins are designed to compensate for interfraction prostate setup variability. This approach has the potential to lower the overall effectiveness of treatment because the prostate gland is a continuously moving target whose motion cannot be accurately accounted for solely on the basis of interfraction movement. More recently, the dosimetric relevance of intra-fraction prostate motion has been recognized, and may be compensated for by continuous real-time adaptive radiation therapy afforded by the Calypso 4D Localization System™. In the current study, the investigators propose to characterize intrafraction prostate motion. The investigators hypothesize that intrafraction prostate motion is correlated with respiratory motion.
RATIONALE: Diagnostic procedures, such as MRI, may help measure oxygen levels in tumor cells. It may also help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying how well MRI works in assessing hypoxia in patients with localized prostate cancer undergoing stereotactic body radiation therapy.
RATIONALE: Vandetanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vandetanib together with docetaxel may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of vandetanib given together with docetaxel in treating patients with advanced solid tumors.
Our objective is to evaluate the clinical outcomes for the anatomic radical perineal prostatectomy (RPP) for the surgical management of prostate cancer. We will report the perioperative, oncologic, and functional outcomes in patients undergoing the radical perineal prostatectomy at our institution.
The purpose of this study is to evaluate the role and effectiveness of conversion to sirolimus versus CNI reduction in renal transplant patients with prostate cancer.
Primary Objectives: 1. To describe patient quality of life (QOL) related to bladder, bowel, and sexual function, as well as mental and physical health, in patients who received neoadjuvant investigational therapies prior to radical prostatectomy (RP) for high risk clinically localized prostate cancer (HRCLPC). 2. To identify medical and demographic variables that are related with quality of life, e.g., hormonal or non-hormonal neoadjuvant treatment, time since surgery, disease recurrence, subsequent treatment, age, ethnicity, and socioeconomic status. Secondary Objectives: 1. To describe treatment satisfaction expressed by patients who have received neoadjuvant investigational therapies prior to radical prostatectomy for high risk clinically localized prostate cancer.
Objectives: Primary: - To evaluate the association of the probability of increase in phosphorylation of platelet-derived growth factor receptor (PDGFR) of > 0.5 in peripheral blood leucocytes following pre-operative docetaxel chemotherapy, with progression-free survival in localized castration-resistant prostate cancer (CRPC) Secondary: - To evaluate the association of the probability of increase in phosphorylated platelet-derived growth factor receptor (PDGFR) expression in peripheral blood leucocytes > 0.5 with indices of tumor regression including PSA-decline by 50% and measures of objective regression of tumor by transrectal MRI following pre-operative docetaxel therapy. - Explore associations of probability of increase in phosphorylated PDGFR in peripheral blood leucocytes following pre-operative docetaxel therapy with plasma PDGF kinetics and spatial and quantitative PDGF and phosphorylated PDGFR expression in tumor and stromal compartments in resected specimens. - Evaluate the association of probability of increase in phosphorylated PDGFR expression in peripheral blood leucocytes following pre-operative docetaxel chemotherapy with overall survival outcomes. - Assess global quality of life measures at baseline and 6 and 12 months post-operatively. - Create a tissue archive comprising tumor and peripheral blood specimens as a suitable resource for future genomic and proteomic studies.
This protocol is designed to collect a small amount of blood and tissue from individuals with prostate cancer for extraction of DNA (genetic material) for the study of the genetic basis of prostate cancer. The study population will include individuals with known prostate cancer and controls without prostate cancer. The study will be conducted in Doha, Qatar at the Hamad Medical Corporation and Weill Cornell Medical College (Qatar). Individuals in the study population will be of Arab descent from Qatar. In this protocol, researchers will survey epidemiologic factors and medical records of patients with prostate cancer in order to study the clinical characteristics of these individuals. The researchers will collect blood and tissue samples to evaluate the genetic characteristics of individuals with prostate cancer. The researchers will also collect blood samples of individuals without prostate cancer to serve as a control. The goal will be to identify genes that are associated with prostate cancer and gene profiles that are associated with differing prognoses in individuals who have prostate cancer.
