Filter by:This phase II trial evaluates Fluorine-18 radiohybrid prostate-specific membrane antigen (18F- rhPSMA)-7.3 positron emission tomography (PET)/computed tomography (CT) scans with and without furosemide for the reduction of bladder activity in patients with prostate cancer that has come back (recurrent) based on elevated levels of prostate-specific antigen (PSA) in the blood (biochemical) after prostate surgery (prostatectomy). Furosemide is a diuretic substance that increases the urine flow into the bladder, thereby decreasing the level of radioactivity within the bladder, which may help to see any abnormal areas that could be masked by the radioactivity within the bladder. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, rhPSMA ligand. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Adding furosemide to 18F-rhPSMA 7.3 PET/CT scans may help to better detect and treat patients with biochemically recurrent prostate cancer.
This phase II trial studies how well time-restricted eating works in reducing side effects of radiation or chemoradiation side effects when compared to nutritional counseling among patients with prostate, cervical, and rectal cancers. Time-restricted eating, also called short term fasting or intermittent fasting, is an eating plan that alternates between not eating food (fasting) and non-fasting periods. Nutritional counseling involves being asked to follow a healthy, balanced diet that includes instructions on what kinds of food are better tolerated during radiation and chemoradiation therapy. This trial may help researchers determine if certain diets may improve the anti-cancer effects of radiation therapy and reduce the side-effects of this treatment. If successful, these diets may be integrated into the future treatment of prostate, cervical, and rectal cancers.
SMMART-ACT is a feasibility pilot study to determine if testing samples from a participant's cancer using a precision medicine approach can be used to identify specific drugs or drug combinations that can help control their disease. The safety and tolerability of the drug or drug combination is also to be studied. Another purpose is for researchers to study tumor cells to try to learn why some people respond to a certain therapy and others do not, and why some cancer drugs stop working. The study population will include participants with advanced breast, ovarian, prostate, or pancreatic malignancies, or sarcomas.
This phase II trial studies how well gallium-68 PSMA-11 PET/CT or PET/MRI works in finding prostate cancer cells that have come back (recurrent) in patients with prostate cancer. Gallium-68 PSMA-11 is a type of radioactive compound, called a radiotracer, which is injected in the vein and can accumulate in tumor cells to generate a signal detected by PET/CT or PET/MRI imaging. This may help researchers in finding recurrent prostate cancer cells in patients with prostate cancer.
This exploratory study conducted under the RDRC program studies the biodistribution of 99mTc-PSMA-I&S in patients with prostate cancer who undergo pelvic lymph node dissection. Prostate specific membrane antigen (PSMA)-targeted radio-guided surgery uses the preoperative intravenous administration of a PSMA-ligand called PSMA-imaging and surgery (I&S) labeled with the gamma-emitter radioisotope Technetium-99m (99mTc). Giving 99mTc-PSMA-I&S may detect PSMA-expressing lymph nodes during surgery using a gamma probe and may help guide doctors to detect prostate cancer that has spread to the lymph nodes.
This phase II trial studies how well white button mushroom supplement works in reducing prostate-specific antigen (PSA) levels in patients with prostate cancer that has come back (recurrent) or has favorable risk and has not undergone any therapy (therapy naive). PSA is a blood marker of prostate growth. White button mushroom supplement may affect PSA level, various parameters of immune system and levels of hormones that may have a role in prostate cancer growth.
This phase I trial investigates the side effects of cabozantinib and nivolumab in treating patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment for human immunodeficiency virus (HIV). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may shrink or stabilize cancer in patients undergoing treatment for HIV.
This exploratory study investigates how a new imaging technique called FAPI PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with prostate cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers including prostate cancer.
This phase II trial studies the side effects of radiation therapy (hypofractionated proton beam therapy or IMRT) for the treatment of prostate cancer that has come back (recurrent) or that has spread to a limited number of sites (oligometastatic) following primary localized treatment. Hypofractionated proton beam radiation therapy delivers smaller doses of radiation therapy over time and may kill more tumor cells and have fewer side effects. IMRT uses high energy x-rays to kill tumor cells and shrink tumors. This trial is being done to find out if a shorter course of radiation therapy is better with fewer side effects for patients with recurrent prostate cancer.
This phase II trial studies how well antiandrogen therapy (leuprolide, apalutamide, and abiraterone acetate) and stereotactic body radiation therapy (SBRT) works in treating patients with prostate cancer that has come back and has spread to other parts of the body. Drugs used in chemotherapy, such as leuprolide, apalutamide, and abiraterone acetate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving antiandrogen therapy and SBRT may work better in treating patients with prostate cancer.
