Recruiting studies
- NCT07788625Recruiting
Focal therapy for prostate cancer not visible on MRI
This study tests a new way to treat prostate cancer that is not visible on MRI but is detected by a special PET scan. The treatment is a focal therapy that targets only the cancer while sparing healthy tissue, and it aims to control the cancer with fewer side effects.
Hong Kong, 香港島Ages 50 years+ - NCT07643558Recruiting
Fish oil and weight training for cancer patients' muscle health
This study tests whether taking fish oil supplements combined with progressive weight training exercises can help preserve or build muscle strength in cancer patients undergoing treatment. The goal is to help you maintain physical function and quality of life during cancer care.
Erlangen, BavariaAges 18 years+ - NCT07635238RecruitingPhase 2
Lower Dose Radiation for Prostate Cancer
This trial tests whether a lower dose of radiation can effectively treat prostate cancer while reducing side effects. It is for men with certain types of prostate cancer that are visible on an MRI.
Basking Ridge, New JerseyAges 18 years+ - NCT07467928Recruiting
AI colonoscopy's long-term effect on advanced polyps
This study looks at how well AI-assisted colonoscopy prevents new advanced polyps from forming over the long term. It's for people who were in our earlier AI colonoscopy study and are healthy enough for a follow-up scope.
Hong KongAges 18 years+ - NCT07398690Recruiting
MRI-guided approach for prostate cancer diagnosis
This trial tests if using MRI and a blood test called PHI can help decide who needs a prostate biopsy. It aims to avoid unnecessary biopsies while still catching cancer early.
SeoulAges 20 years+ - NCT07339761Recruiting
Sexual health support for bladder cancer patients
This study from the University of Aarhus looks at ways to support sexual health in people who have been treated for bladder cancer. If you are a Danish-speaking adult who had bladder cancer treatment about a year ago and have noticed changes in sexual function, you may be able to join.
AarhusAges 18 years+ - NCT07325721RecruitingPhase 2
Shorter radiation with a focused boost for high-risk prostate cancer
This trial tests a shorter course of radiation therapy with an extra 'boost' to the most aggressive part of the tumor, combined with hormone therapy, for men with high-risk or locally advanced prostate cancer that has not spread outside the pelvis.
Charleston, South CarolinaAges 18 years+ - NCT07308990Recruiting
Comparing limited vs. full lymph node removal during prostate surgery
This trial compares two types of lymph node removal during prostate cancer surgery to see if removing fewer lymph nodes is just as effective. It is for men with prostate cancer that has not spread beyond the pelvis.
Lyasny, Minsk OblastAges 18 years+ - NCT07225205Recruiting
Home IV fluids after bladder removal surgery
This trial tests if giving IV fluids at home after bladder removal surgery is safe and helpful. It aims to reduce dehydration and hospital visits after you go home.
Baltimore, MarylandAges 18 years+ - NCT07219303Recruiting
Adaptive radiation therapy for intermediate- or high-risk prostate cancer
This trial tests a type of radiation that adjusts to changes in your prostate during treatment. It aims to improve accuracy and reduce side effects for men with intermediate- or high-risk prostate cancer.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07204665Enrolling by invitation
Emergency surgery vs. stent for colon cancer blockage
This study compares emergency surgery to placing a stent first for people with a blocked colon from cancer. It also looks at whether a special recovery program (ERAS) helps you heal faster after surgery.
Bilbao, VizcayaAges 18 years+ - NCT07180381Recruiting
A closer look at prostate MRI to avoid unnecessary biopsies
This study uses repeat MRI scans to monitor men with an intermediate suspicion of prostate cancer, aiming to reduce unnecessary biopsies while still catching significant cancers early.
Emmen, DrentheAges 18 years+ - NCT07161713Recruiting
Relaxation and stress reduction study for cancer survivors
This study is testing whether relaxation and stress reduction techniques can help your body heal at a cellular level. If you are a cancer survivor who finished treatment at least 6 months ago, you may be able to join.
Stony Brook, New YorkAges 18 years+ - NCT03893929Recruiting
Test new markers to help diagnose prostate cancer
This study looks for new biological markers in men to improve how prostate cancer is diagnosed and followed. If you have signs that might be prostate cancer, your tests may help researchers find better clues for future care.
ShatinAges 18 years+ - NCT05443412Recruiting
AI tool to help detect prostate cancer from MRI and biopsy results
This study tests an artificial intelligence (AI) tool that may improve how doctors detect prostate cancer using imaging and biopsy information. It could help better identify cancer that is suspected based on PSA blood tests and rectal exam findings.
Hong KongAges 18 years+ - NCT06604130Enrolling by invitation
Prostate cancer diagnosis using blood exosomes
This study explores whether a simple blood test that looks at tiny particles called exosomes can help diagnose prostate cancer, possibly reducing the need for biopsies. If you have higher PSA levels and are scheduled for a biopsy, this trial might be a fit.
Lanzhou, GansuAges 18 years+ - NCT06396806Enrolling by invitation
Sigmoid cancer surgery with or without dye tracing
This trial compares two surgical approaches for sigmoid colon cancer to see if using a special dye to see lymph nodes during surgery leads to better outcomes.
Guangzhou, GuangdongAges 18–75 - NCT06347705RecruitingPhase 2
Vaccine plus standard therapy for prostate cancer before surgery
This trial tests an experimental vaccine (2141-V11) combined with standard hormone therapy and an anti-androgen drug before prostate removal surgery. It aims to see if the combination can help the immune system fight the cancer more effectively.
Basking Ridge, New JerseyAges 18 years+ - NCT05946213RecruitingPhase 3
Shorter radiation treatment for high-risk prostate cancer
This trial tests whether a shorter course of radiation works as well as the usual longer course for people with high-risk prostate cancer. The goal is to keep cancer control while possibly reducing treatment time and inconvenience.
Birmingham, AlabamaAges 18 years+ - NCT05931419Recruiting
Radiation versus surgery for high-risk prostate cancer
This trial compares two standard treatment options—radiation or surgery—for people with high-risk prostate cancer that has not spread. The goal is to see which approach works better for long-term cancer control and side effects.
AlkmaarAges 50–75 - NCT05454488RecruitingPhase 2
Study focal freezing for intermediate-risk prostate cancer
This trial tests whether freezing only the cancer area in the prostate (focal cryotherapy) can control intermediate-risk prostate cancer. It aims to limit treatment to one tumor focus while closely checking results with targeted and follow-up testing.
Houston, TexasAges 18 years+ - NCT05361798RecruitingPhase 2
Testing immune response after prostate radiation with or without a drug
This study checks how your immune system’s cancer-fighting cells change after stereotactic body radiation (SBRT) to the prostate. It compares SBRT alone versus SBRT plus an immunotherapy drug (PDS01ADC) in men with intermediate- or high-risk localized prostate cancer treated with hormone therapy (ADT).
Bethesda, MarylandAges 18 years+ - NCT05144152Recruiting
Testing M3 and FIT to predict polyp return in colon exams
This study checks how well two lab tests (M3 and FIT) can predict whether advanced colon polyps (adenomas) will come back. If you’ve had adenomas found on a prior colonoscopy, these results may help plan future surveillance.
Shatin, New TerritoriesAges 18 years+ - NCT05065801RecruitingPhase 2
New metastatic pancreatic cancer: targeted chemo before FOLFIRINOX
This trial tests whether adding Gembrax (a combination that includes gemcitabine and nab-paclitaxel) before standard FOLFIRINOX works better than FOLFIRINOX alone in people with pancreatic cancer that has already spread. It looks at whether this “step-up first” approach improves results and is still tolerable.
