Significant advances in molecular nuclear medicine imaging in prostate cancer have been achieved in recent years. In particular, the introduction of prostate-specific membrane antigen (PSMA) -based tracers has significantly influenced diagnostic imaging of prostate. If cancer recurs after surgical removal of the prostate, targeted PSMA PET (positron emission tomography) can detect metastases even at very low PSA (prostate-specific Antigen) values. This increasingly allows individualized specific therapy of patients with prostate cancer recurrence. PSMA PET has now been included in national and international guidelines for the diagnosis of patients with biochemical recurrence of prostate cancer. Especially in patients in good general condition, with potentially longer life expectancy and early localized PSA recurrence, advances in molecular imaging are increasingly turning local therapy concepts into focus. Here both, radiotherapeutic (salvage radiotherapy of the lymphatic drainage) and surgical interventions (salvage lymph node dissection = removal of the pelvic lymph nodes) are offered on an individual basis. These regional therapies mainly aim to achieve a delay of further progression of the prostate cancer disease, and thus delay the initiation of palliative, sustained drug therapy. Previous standard or common practice at salvage lymph node dissection is the removal on both sides of the pelvic lymph nodes even if only one-sided suspicious lymph nodes are detected on imaging. Although the complications of salvage lymph node dissection are usually minor and manageable, they can still lead to impaired lymphatic drainage, leg edema, lymphocele formation or other surgical complications. The aim of the present study is to investigate whether a unilateral pelvic lymph node dissection on the side of conspicuous PSMA PET is sufficient and a dissection on the contralateral side can be dispensed without negatively impacting oncological outcomes and thereby sparing the patient the potential additional complications of a bilateral pelvic lymph node dissection.
Currently, lymph node dissection is standard of care during prostatectomy of intermediate risk tumors at the Martini Clinic. It allows the assessment of possible but unlikely lymph nodes metastases. In case of lymph node metastasis, depending on the number of affected lymph nodes, an adjuvant radiation with or without additional hormone therapy may be discussed in order to stop or delay further progression of the disease. Since the procedure carries additional risks, it is controversial. The risks include prolonged surgery duration, injury of vessels and nerves, as well as disorders of lymphatic circulation after surgery. Moreover, formation of lymphoceles (accumulation of lymph fluid in the tissue) are common, which may result in soft tissue swelling, thrombosis, inflammation and additional surgical procedures. Therefore, the aim of this study is to evaluate whether the removal of the lymph nodes during prostatectomy positively influences the course of the disease in patients with intermediate risk prostate cancer, or if the lymph node dissection does not have any influence on the recurrence of the disease and therefore further therapies. In this case, the omission of lymph node dissection may avoid an unnecessary expansion of the operation and the potentially associated side effects linked to it. This is particularly of interest considering the rapidly advancing technical possibilities, both in imaging and in the treatment of prostate cancer, since this enables an earlier and more individual intervention in the case of recurrence.
This study aims at evaluating if placement of CLARIX® CORD 1K during robotic prostatectomy decreases the time to achieve complete erectile and urinary function after the surgery. As part of the study, the patient will be asked to answer various questions after the surgery regarding sexual and urinary function.
This will be a confirmatory, prospective, open-label, single-arm, reader-blinded, multi-centre phase 3 study to assess the diagnostic accuracy and safety of Ferrotran®-enhanced MRI in comparison to unenhanced MRI in the detection of pelvic lymph node metastases in newly-diagnosed adult patients with prostate cancer and an intermediate to high risk for lymph node metastases, based on the D'Amico criteria.
Prostate cancer (PCa) is a high incidence tumor of elderly men. In recent years, its incidence has rapidly increased in China. Serological examination of prostate-specific antigen (PSA) is particularly important in the early diagnosis of PCa, but its specificity is lower in gray areas with PSA between 4-10 ng / ml. Proposition of prostate health index (PHI) strengthens the specificity of PSA gray area prostate cancer diagnosis, but the composition of the index only relies on serological examination, neglects imaging indicators, and cannot be comprehensively evaluated. Based on the preliminary basis of PHI research in the undergraduate department, combined with ultrasound imaging indicators of total prostate volume (TPV), this research group prospectively analyzed the efficacy of PHI combined with TPV to predict prostate cancer in patients with PSA gray areas, and established an improved version of PHI-TPV combination. The prediction model mPHI assesses the sensitivity of the new model to predict the risk of prostate cancer in the Chinese population, provides data support for puncture decisions of middle-aged and elderly male patients in the gray area of PSA in China, and provides reference and guidance for the individualized prevention and treatment of prostate cancer.
Prostate cancer is the second most common cancer among Canadian men of which approximately 20-30% present with high-risk tumour characteristic. Although surgery can be curative in patients evidencing pathological high-risk disease (extracapsular extension, seminal vesicle involvement, positive surgical margins), a large proportion will develop biochemical failure within years from the surgical procedure. The failure rate is even more pronounced in those patients that present with high prostate specific antigen (PSA) levels, pT3 disease, positive margins and Gleason score ≥8 with an estimated 75% failure rate at 10 years. Post-operative radiotherapy (RT) has been shown in three randomized trials to significantly decrease the biochemical failure rate and in one of the trials a survival benefit was also seen with the addition of post-operative RT and is considered by many investigators standard therapy in patients with pathological high-risks factors even in absence of biochemical failure.
A randomized, multicenter, prospective PHASE II trial to assess the effect of short- versus long-term adjuvant ADT with high dose salvage radiotherapy on distant metastasis free survival in case of biochemical relapse (BR) after radical prostatectomy.
The purpose of this research study is to determine if the interpretation of multiparametric MRI (mpMRI) with an algorithm called habitat risk score (HRS) in combination with a panel of blood and urine biomarkers is more effective at detecting prostate cancer than standard of care interpretation of mpMRI with the Prostate Imaging Reporting and Data System (PIRADS).
The study offers focal salvage brachytherapy for prostate cancer patients with a local recurrence after primary defintive radiotherapy
