Filter by:This clinical trial will evaluate PSMA PET additive value for significant prostate cancer (sPCa) diagnosis in men with negative/equivocal MRI
Constitution of a biological collection within the framework of the establishment of a diagnostic, prognostic and active surveillance test for prostate cancer from long non-coding RNA biomarkers, in 3 cohorts of patients, with cancer of the prostate, with suspected cancer without biopsy confirmation or with prostatic hyperplasia and healthy donors. This biological collection will also be used as a support for further researches on the identification of biomarkers and genetic markers to improve the prognosis and diagnostic management of patients with prostate pathologies.
The present study aimed to compare the diagnostic accuracy, radiation exposure, complication rates between 68Ga-PSMA PET/CT guided robotic arm assisted prostate biopsy and MRI directed TRUS guided prostate biopsy.
Participants will either receive treatment with standard SBRT and the study drug Radium (Ra-223) dichloride, or standard SBRT alone.
This study aims to define the natural history of men at high genetic risk for prostate cancer on the basis of specific germline genetic mutations or a positive family history and evaluate the utility of prostate MRI as a screening tool. The hypothesis is that this targeted population of men are at elevated risk of developing prostate cancer compared to the general population, and enhanced screening with MRI will enable early detection and diagnosis of potentially aggressive prostate cancer, characterization of the penetrance of specific mutations, and potentially identify new genetic risk mutations.
This study is researching an investigational drug called REGN4336. Some participants may receive additional investigational drugs in combination with REGN4336. These additional drugs include REGN5678, cemiplimab and sarilumab. The main purpose of this study is to determine the safety, tolerability (how the body reacts to the drug) and effectiveness of REGN4336 alone, in combination with cemiplimab, or in combination with REGN5678. REGN4336, cemiplimab and REGN5678 are a type of treatment for cancer called immunotherapy,and are intended to activate T-cells to attack cancer cells. This study has 2 parts. The purpose of Part 1 is to determine a safe dose of REGN4336 when given alone or when given in combination with cemiplimab or REGN5678. The purpose of Part 2 is to use the REGN4336 dose(s) determined in Part 1 to further test how well REGN4336 works to shrink tumors either when given alone or in combination with cemiplimab or REGN5678. This study is looking at several other research questions, including: - What side effects may happen from taking REGN4336 alone, in combination with cemiplimab, or in combination with REGN5678? - How much REGN4336 is in the blood at different times when it is given alone, in combination with cemiplimab, or in combination with REGN5678? - Does the body make antibodies against the study drugs (REGN4336, cemiplimab, or REGN5678)?
This is a prospective, interventional pilot study to evaluate the feasibility of randomizing patients diagnosed with prostate cancer to different treatment schemes according to their risk. Patients with a diagnosis of prostate adenocarcinoma (confirmed by biopsy), without signs of metastasis outside the pelvis in the staging study and without prior radiotherapy (RT) to the pelvic region will be recruited. The definition of risk group from the international guide National Comprehensive Cancer Network will be used. - Low risk - Favorable intermediate risk - Unfavorable intermediate risk - High risk The use of hormonal blocking will be at the discretion of each treating physician. The radiotherapy simulation will be carried out according to the institutional protocol for the treatment of prostate cancer. According to the risk group of the patients, the following randomization will be carried out: - Low / intermediate favorable risk: Patients will be randomized to receive SBRT to prostate 36.25 Gy in 5 fractions, alternate days or weekly, with VMAT (technique and 6 Mega-voltage (MV) X-rays vs to SBRT to prostate 26 Gy in 2 fractions, 1 weekly fraction, with VMAT technique and 6 Mv X-rays. The volumes to be treated, ¨Clinical target volume¨ (CTV) will be defined as the prostate, according to the consensus of the Radiation Therapy Oncology Group (RTOG). - Intermediate unfavorable risk and high risk: Patients will be randomized to receive SBRT to the prostate and seminal vesicles, 36.25 Gy in 5 fractions, alternate days or weekly, with VMAT technique and 6 MV X-rays vs SBRT to pelvis scheme of 25 Gy in 5 fractions with simultaneous integrated boost up to 36.25 to the prostate and seminal vesicles, with the same technique. - Patients with positive pelvic node: Will be randomized to moderate hypofractionated RT , completing a dose of 44 Gy in 20 fractions to the pelvis with a simultaneous integrated boost up to 54-60 Gy in 20 fractions to metastatic lymphadenopathy and prostate with seminal vesicles, completing 60 Gy to prostate and seminal vesicles or to ultra hypofractionated RT to the prostate and macroscopic lymphadenopathy to 35 and 30-35 Gy respectively and 25 Gy in 5 fractions to the elective nodal areas.
Early and correct diagnostic staging is paramount to keep patients with newly diagnosed prostate cancer in the correct treatment tract to avoid under- and overdiagnosis in prostate cancer staging. With accurate staging, the investigators aim to save patients from side effects of insufficient or too extensive treatment. The investigators hypothesize that precise staging will lead to optimized individualized treatment and subsequently to prolonged survival and increased quality of life. Prostate cancer is a very heterogeneous disease varying from indolent tumors to aggressive cancer types. About one-fifth of patients with newly detected high- or intermediate-risk prostate cancer present with bone metastases and their 3-years survival is less than 50%. Precise staging is required for planning relevant treatment that has the potential to increase survival. The prostate-specific membrane antigen (PSMA) is overexpressed in prostate cancer cells and can serve as a target for precise diagnosis and staging. PSMA-positron emission tomography/computed tomography (PET/CT) has shown to be more accurate than traditional imaging, but there is a need for prospective trials analyzing the impact of primary staging with PSMA-PET/CT on treatment planning and patient benefit. In a prospective multicenter study, the investigators plan to include 448 patients and randomize 1:1 to either traditional imaging or PSMA-PET/CT. The investigators aim to analyze whether PSMA-PET/CT increases progression-free survival and quality of life. Further, the investigators aim to validate the accuracy of primary staging with PSMA-PET/CT compared with conventional imaging.
