Active clinical trials for "Prostatic Neoplasms"

HS-20093 is a fully humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. The objectives of this study are to investigate the anti-tumor activity, safety and pharmacokinetics of HS-20093 in Chinese patients with metastasis Castration Resistant Prostate Cancer. This is a phase 2, open-label, multi-center study to evaluate the efficacy, safety, tolerability and pharmacokinetic (PK) of HS-20093 as a monotherapy in subjects with metastasis castration resistant prostate cancers (mCRPC) and other solid tumors.

Multicenter, open-label, parallel-group, phase II randomized study in patients with oligometastatic prostate cancer with 1-3 asymptomatic metastases of the soft tissue or bone. Eligible patients will be randomized at 1:1 ratio to Stereotactic Radiotherapy followed by Lu-PSMA (arm A) or Stereotactic Radiotherapy (arm B)

This prospective, open randomized clinical trial seeks to investigate whether radical prostatectomy with androgen deprivation therapy improves prostate-cancer specific survival and quality of life in comparison with radical radiation treatment with androgen deprivation therapy among patients diagnosed locally advanced prostate cancer. Lack of extensive PSA screening in mainland China, many new cases of prostate cancer are LAPCa. Surgery and/or radiation plus attempted chemotherapy are curative treatment for advanced solid malign tumors to control and eliminate the local and micro metastases. LAPCa is easy to metastasis, relapse and has a poor prognosis. For LAPCa, a single RP approach is generally not the preferred option because it is generally considered that radical surgery is difficult to completely remove the lesion and the long-term prognosis is not ideal. However, androgen deprivation therapy promotes the prognosis of LAPCa with lymph nodes or seminal vesicle metastases and improves the local control rate of tumor. What is more, for early localized prostate cancer, RT has similar efficacy to RP, for advanced tumor RT can not only relieve urinary tract obstruction and other symptoms, but also improve biochemical progression free survival and local oncological control. A randomized clinical trial comparing two multimodal treatment including RP or RT with ADT regimens is therefore warranted.

This trial studies 7 Tesla magnetic resonance imaging (MRI) in diagnosing cognitive impairment in patients with prostate cancer that has not spread to other places in the body (non-metastatic) and who have or have not received androgen deprivation therapy (ADT). The MRI machine uses a strong magnet and radio wave to make images of the inside of the body. A stronger magnetic field allows greater signals and more detailed visualization of the structure and function of human body. Giving 7 Tesla MRI may help doctors learn if patients that receive ADT show more signs of cognitive dysfunction or brain fog compared to patients to patients that do not receive ADT.

This project focuses on African American (AA) men and Hispanic/Latino (H/L) men with prostate cancer (PCa) in Brooklyn/Queens catchment. Evidence from randomized clinical trials support the efficacy of decision navigation intervention, with navigated patients showing greater confidence in their decisions about cancer treatment and less regret. The investigators will develop and test the acceptability and feasibility of a decision navigation intervention for AA or H/L men with prostate cancer. The primary aim for this study is to adapt and tailor an evidence based decision navigation intervention for AA and H/L men newly diagnosed with prostate cancer (PCa). The investigators hypothesize that men in the decision navigation intervention arm will report higher levels of decision self-efficacy, less decisional conflict, and regret about their treatment decisions compared to men engaged in standard of care.

To evaluate of the value of radical prostatectomy and extended pelvic lymph node dissection in locally advanced prostate cancer after neoadjuvant hormonal therapy with or without docetaxel chemotherapy.

Prostate cancer (PCa) is the most common cancer among men and is even more common in the military and veteran population. For patients with advanced prostate cancer, the most common treatment includes lowering the levels of the hormone testosterone as much as possible. This is called "androgen deprivation therapy" or "ADT". Unfortunately, ADT also causes patients to be fatigued, weak and to loose muscle. This is often referred to as "sarcopenia" and it leads to falls, poor quality of life and higher risk of death. Currently, there is no treatment for sarcopenia because the investigators do not understand the mechanisms that cause it. The mitochondria is the part of the cells responsible for providing energy to muscles but to this date the investigators do not know if it is affected in prostate cancer patients with sarcopenia due to ADT. The overall goal of this proposal is to establish if the mitochondria is responsible for sarcopenia in patients with prostate cancer receiving ADT. The investigators will measure mitochondrial function, muscle mass and strength, and feelings of fatigue and quality of life in patients with prostate cancer before starting and after 6 months of ADT.

Prostate gland is a clinically important male sexual organ and its main function is for the production of semen. Globally, it is the second most common cancer in men globally and is also the fifth cancer cause for death in male. Despite the improvement in the understanding of prostate cancer, the current usage of serum prostate specific antigen (PSA) as a diagnostic marker is still not ideal. Many patients with elevated PSA and then subjected to prostate biopsy were found to have no prostate cancer. Therefore, there is a need to discover new biological markers to improve the current situation in diagnosis and also management of prostate cancer. From the earlier small-scale studies, urinary spermine levels have been shown to correlate well with prostate cancer diagnosis and cancer aggressiveness. Due to its nature, it could provide a more convenient and non-invasive method for detecting prostate cancer. The purpose of this study was to collect urine samples to study the role of potential new urine diagnostic markers (including Spermine and others) for prostate cancer diagnosis.

Prostate cancer (PCa) is the second most frequently diagnosed cancer in men worldwide, accounting for 15% of all male cancers. In 2015, there were 220,800 estimated new cases of prostate cancer and 27,540 deaths by PCa, making this disease the second leading cause of cancer-related death for North American men. Men with PCa may develop lower urinary tract symptoms (LUTS) when prostate tumors invade or compress the prostatic urethra, the bladder or the neurovascular bundles, or when the prostate is enlarged. It has been estimated that over 40% of men with PCa experience moderate or severe LUTS. LUTS can impact profoundly on a man's quality of life (QoL); an effect that increases with increasing LUTS severity. Transurethral resection of prostate (TURP) can offer immediate relief of the obstruction in patients with benign prostatic hyperplasia (BPH). In contrast, palliative TURP (p-TURP) (the so-called "channel" TURP), is transurethral resection of prostate tissue in a patient with metastatic or locally advanced and/or previously treated PCa to alleviate obstructive voiding symptoms. Al¬though TURP is commonly performed to relieve bladder outlet ob¬struction (BOO) symptoms in patients with BPH, little known about the outcome of palliative transurethral plasma kinetic resection of prostate (p-TUPKRP) in patients with ad-vanced PCa. Gonadotropin-releasing hormone (GnRH) agonists as androgen deprivation therapy (ADT) are the standard treatment for many patients with PCa, particularly those with advanced or metastatic disease. The impact of ADT on tumor control and achieving the reduction in prostate specific antigen (PSA) is well established. But there is less information available on the effects on LUTSs in men with PCa. Some short-term studies of ADT with the GnRH antagonist or with ADT in the neoadjuvant setting have demonstrated reductions in LUTSs, measured by the International Prostate Symptom Score (IPSS). There are few published data on the longer-term effects of ADT on LUTSs, apart from an earlier interim analysis of data from the current study. In this study, p-TUPKRP combined with ADT will perform for 50 patients with advanced PCa complicated with severe LUTS. As a control, other 50 advanced PCa patients with same symptoms will be treated with ADT only. Some clinical data, including PSA, IPSS, QoL, Urinary flow rate (UFR), ECOG Score, Overall survival (OS), progression-free survival (PFS), will be analyzed. It is expected to explore the efficacy and safety of the combination therapy to advanced PCa with severe LUTS.
