Active clinical trials for "Prostatic Neoplasms"

This prospective study at MAMC evaluates the utility of a rigid pelvic external immobilization compared to limited immobilization using a novel real-time localization system of the prostate. The sample population will include patients referred to the radiation oncology services of both facilities for definitive treatment of prostate cancer. The study will enroll 20 subjects from MAMC and evaluate data on 860 radiation therapy fractions. Subjects will have Beacon® Transponders implanted into the prostate to more precisely localize the position of the organ during radiation therapy. They will be randomized to rigid pelvic immobilization using a Vac-Lok® system or limited immobilization with a band around the patient's feet. They will then undergo radiation therapy planning with standard planning target margins. The Calypso® 4D Localization System will monitor, in real time, the position of the prostate target and adjust radiation treatments as required to ensure accurate treatment of the prostate gland. The time of, the number, and extent of adjustments will be recorded for analysis. Hypothesis: 1. When treating only the prostate, treatment with rigid pelvic immobilization is not necessary when using real-time, state-of-the-art motion tracking of the prostate.

RATIONALE: Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify genes related to cancer. PURPOSE: This clinical trial is studying blood and tumor samples from men with an inherited risk of prostate cancer.

Primary: to investigate the effects of DNA repair gene polymorphisms on prostate cancer susceptibility, pathological grade, disease stage and clinical outcome Secondary: to understand the association between DNA repair gene polymorphism and prostate cancer and provided important information for screening, prevention and treatment of prostate cancer

To evaluate the cancer control for prostate cancer patients treated with focal therapy.

The investigators provided a multicenter analysis aiming to investigate, in a clinical practice setting, the prognostic relevance of previous primary radical prostatectomy (RP) or external beam radiotherapy (RT) in terms of Overall Survival as opposed to patients with no primary treatment performed, in a cohort of patients enrolled in 223-Ra treatment for mCRPC. 223-Ra has been administered from investigators according to the current label authorization and all patients underwent 223-Ra treatment, until disease progression or unacceptable toxicity.

Objectives: To establish if there are differences between an ultrasound-guided transrectal prostate biopsy (BPTE) and a transperineal prostatic biopsy (BPTP) with and without a multiparametric Magnetic Resonance (RMmp) in patients with clinical suspicion of prostate cancer (PC) to first prostatic biopsy in terms of: Rate of detection and diagnosis of prostate cancer. Aggressiveness of the detected tumors. Association of the marker [-2] proPSA and the prostate cancer health index (PHI) and microRNAs for the diagnosis of tumors. Adverse effects of the intervention and subjective perception of the patient: pain and degree of satisfaction, and impairment of quality of life. Cost-effectiveness analysis of the different intervention options. Study Design: Randomized, single-blind prospective clinical study to compare four schemes: RMmp + BPTE vs. BPTE 12 cylinders vs RMmp + BPTP vs BPTP 12 cylinders. Study population: Patients with clinical suspicion of prostate cancer with PSA between 3-20 ng / mL and normal or abnormal rectal examination, candidates for a first prostate biopsy. Research techniques: BPTE standard of 12 cylinders compared to RMmp previous to BPTE vs BPTP of 12 cylinders compared to BPTP with previous RMmp.

The purpose of this study is to evaluate the feasibility of electrical stimulation of nerves responsible for erectile function to evoke penile erection after surgery to remove the prostate (prostatectomy).

This is an observational, prospective (study following participants forward in time), multi-center (study conducted in more than 1 center) study to identify the risk factors, then develop and validate the predictive Nomogram of metastatic castration-resistant prostate cancer (mCRPC) that will effectively predict the early onset mCRPC in patients receiving androgen-deprivation therapy (ADT). The entire duration of study will be approximately 3 year. Participants will primarily be evaluated for achieving biochemical or radiological progression after receiving ADT based on EAU 2017 practice guideline criteria. Serum testosterone, prostate specific antigen (PSA), alkaline phosphatase (ALP) and blood routine will be monitored throughout the study.

Prostate brachytherapy is an effective treatment option for men with localized prostate cancer, with excellent cure rates and a favorable toxicity profile. With the current needle insertion technique, seed placement inaccuracy is primarily caused by needle deflection and soft tissue deformation, which both occur during the brachytherapy operation. This study will accrue 20 patients undergoing prostate brachytherapy implants and acquire a series of ultrasound images, video clips and one CT scan.

The purpose of this study is to evaluate if there is a difference in quality of life (as measured by FACT-P) in patients treated with androgen deprivation therapy (ADT) for biochemical failure (PSA recurrence) following surgery or radiation for prostate cancer depending on when ADT is initiated.
