Active clinical trials for "Prostatic Neoplasms"

An improved diagnosis of bone metastases in prostate cancer patients can have a significant impact on treatment strategy and probably survival as well. The primary purpose of the project is to determine the diagnostic accuracy of bone SPECT-CT, choline-PET-CT, PSMA-PET-CT, NaF-PET-CT and Whole-body MRI in the diagnosis of bone metastases in prostate cancer patients.

Patients will be submitted to a multiparametric MRI examination of the prostate. Subsequently, all participants will be randomized (1:1) into both study arms. In study arm A patients will be submitted to the gold-standard which comprises systematic transrectal ultrasound-guided prostate biopsy. In study arm B patients will be submitted to targeted prostate biopsy based on the multiparametric MRI findings.

Circulating tumor cells (CTCs) have the potential to provide a surrogate for'real-time biopsy' of tumor biological activity. Enumeration and molecular characterization of CTCs in prostatic cancer could play an important role in diagnosis, predicting the risk for tumor recurrence, and providing novel target therapy biomarkers. In view of these facts, the investigators wanted to demonstrate the value of multiparameter flow cytometry in detecting human tumor cells of prostatic cancer in normal peripheral blood after cryosurgery with or without dendritic cell(DC)-cytokine-induced killers(CIK) treatment, and the investigators also compared the specificity with reverse transcriptase polymerase chain reaction (RT-PCR) method.

Biomarkers of bone resorption will be measured in the blood of patients with bone metastases from prostate cancer during the course of their illness. Changes in these biomarkers will be correlated with the patient's treatment with antiandrogen therapy and bisphosphonates and the response and/or progression of their cancer. It is hoped that serial measurement of these biomarkers may allow therapeutic monitoring in the future with successful individualisation of bisphosphonate therapy for metastatic prostate cancer.

This research study is being done to collect regular and routine follow-up information related to the outcome of treatment for prostate cancer. This study is also being done to relate treatment outcome to measurement of substances in the blood such as prostate-specific antigen (PSA) and other markers. Also environmental and genetic factors that might be responsible for prostate cancer are being investigated.

The purpose of this study is to evaluate an imaging capability Prostate Mechanical Imager (PMI), a PC-based device utilizing a transrectal probe with pressure sensor arrays and motion tracking system, aimed at providing composite elasticity images of the prostate.

The goal of this study is to learn more about how we measure depression in elderly cancer patients (patients aged 70 and older). Depression is one of the most common causes of emotional distress in the elderly and continues to be under-recognized. This is a problem because depression can have a negative impact on quality of life. The symptoms of depression are linked to poor health outcomes and higher costs of health care. In fact, depression is one of the top five concerns facing the elderly today.

Primary objective : The primary objective is to evaluate the diagnosis performance of FFOCT for cancer detection in patients undergoing TRUS prostate biopsy, as compared to standard pathological evaluation. Secondary objective: Evaluate predictive values of FFOCT for cancer detection on prostate biopsy cores Evaluate the value of FFOCT for cancer characterization on prostate biopsy cores Evaluate the reproducibility of FFOCT evaluation for cancer detection on prostate biopsy cores Evaluate the learning curve of FFOCT evaluation on prostate biopsy cores Evaluate FFOCT procedure time

Adrenal androgens are serum biomarkers of interest that may help guide abiraterone acetate treatment, particularly at the time of progression. Biomarkers may also help identify pathways to resistance of abiraterone acetate treatment. The most practical way of approaching this question is to explore surrogate biomarkers of prostate cancer including quantification of pharmacodynamic endocrine biomarkers.
