Filter by: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.
Exploratory study of SLPI expression in human prostate cancer patients This is a no-profit exploratory study about the expression of SLPI in human prostate cancer patients that will enroll about 200 patients admitted for suspect prostate cancer to Careggi University Hospital. We will verify whether an increase SLPI levels in the sera may serve as biomarker of cancer progression.
Radiotherapy has an important role in the treatment of prostate cancer both as curative treatment and postoperative or salvage ones. Several studies demonstrated a significant reduction of lymphocytes during RT but there are only a few studies monitoring these cells in the treatment of prostate cancer. This study will enroll 50 patients with hystologically proven prostate cancer who will undergo to radiotherapy according to Institutional protocols. This study aims to evaluate the effect of RT on immuno-regulatory B, NK, T, B and T lymphocyte subpopulations (Breg and Treg) and plasma cells, quantitative / qualitative changes,their correlations with the clinical course of the disease and acute and late toxicity. In parallel, using multicolor panels (12 colors) we will evaluate the expression of inhibitory checkpoints and TGFβ signaling. The final objective is to identify new therapeutic targets to be combined with RT.
Dose escalation is nowadays a standard strategy in radiotherapy for prostate cancer. Besides, it is believed that due to the radiobiology characteristics of prostate cells (low alpha/beta ratio), the delivery of higher radiation doses per fraction could theoretically improve the efficacy of the treatment. In this context, the combination of prostate brachytherapy and external beam radiotherapy (EBRT) has proven to be the most effective method of dose escalation significantly improving disease control in randomized clinical trials. Unfortunately, this strategy is also associated with an increased risk of acute and late adverse events compared to conventional EBRT alone. It has been proposed that this increase in adverse events could be related to the use Low-Dose-Rate (LDR) brachytherapy and that High-Dose-Rate (HDR) brachytherapy (a more modern and accurate procedure) could reduce this risk. On the other hand, Stereotactic Ablative Radiotherapy (SABR) is a high-precision radiation technique that allows the delivery of higher doses per fraction in fewer sessions, reducing the total treatment time. The investigators hypothesized that the combination of two highly conformal radiation techniques (HDR brachytherapy and SABR) could be well tolerated, while reducing total treatment time and therefore improving patient quality of life. This is a single arm Phase II clinical trial designed to test the feasibility, tolerability and impact on quality of life of the combination of High-Dose-Rate prostate brachytherapy and SABR for patients with intermediate and high-risk prostate cancer.
Prostate cancer is the third most common cause of cancer death in men. Most patients with localized prostate cancer will be cured with surgery or radiation therapy, but up to 35% of patients will have their prostate cancer return. Whether it has returned locally or distantly determines which type of treatment they will receive. Current conventional imaging modalities have limitations particularly at low prostate specific antigen levels. This study proposes to use Gallium-68-PSMA-11 (68Ga-PSMA-11) Positron Emission Tomography / Computer Tomography (PET/CT) scans which targets prostate-specific membrane antigens (PSMA) to detect where in the body the prostate cancer has recurred.
This is a diagnostic accuracy prospective, single-centre, open-label, single group assignment interventional study. Its aim is to evaluate the diagnostic accuracy of [68Ga]Ga-PSMA-11 PET/CT in detection of primary tumour and extra prostatic disease (lymph node, soft tissues spread or bone metastases) in men newly diagnosed with Prostate Cancer at Intermediate and High Risk, according to 2019 Prostate Cancer EAU Guidelines Risk Group Stratification (see Study Population paragraph). The investigators are interested in the possible future role of [68Ga]Ga-labelled PSMA PET/CT as integration to conventional imaging mpMRI (with or without CT of the lower abdomen and Bone scan) in the detection of primary tumor and extra-prostatic disease (lymph node and soft tissues spread or bone metastases).
