StockholmAges 18 years+ - NCT05690802Recruiting
Test palonosetron to prevent nausea from chemotherapy
This trial studies whether palonosetron helps prevent nausea and vomiting caused by chemotherapy that has a moderate risk of vomiting. It may help you feel more comfortable during chemo and avoid treatment interruptions from severe nausea.
Xi'an, Shaan'xiAges 18–75 - NCT05693116Recruiting
Study factors that affect outcomes in nasal vestibule cancer
This study looks at survival and outcome factors for people who have squamous cell carcinoma in the nasal vestibule. It uses information from surgery and scans and checks tissue samples to see what predicts recovery or risk of problems later.
Toulouse, TouluseAges 18 years+ - NCT05698576Recruiting
Laser treatment through the skin for men with prostate cancer
This trial tests a laser procedure done through the skin between the scrotum and anus, guided by MRI and ultrasound, for men with certain prostate cancer types. It aims to heat and treat prostate cancer while checking safety and outcomes over follow-up visits.
Hialeah, FloridaAges 50–80 - NCT05696002Recruiting
Track outcomes after advanced pelvic cancer surgery
This study follows people who have advanced pelvic cancer surgery that removes more than one pelvic organ. It’s an observational study, meaning it mainly collects data to help improve how future surgeries and care are planned.
GlasgowAges Any age - NCT05218811Recruiting
Cryo treatment with partial kidney surgery for kidney tumors
This study looks at using a cold (cryoablation) treatment along with partial kidney surgery to treat certain kidney tumors. It may help shrink or control the tumor while preserving more healthy kidney tissue.
Miami Lakes, FloridaAges 55–65 - NCT02381990Recruiting
MRI- and ultrasound-guided freezing treatment for low-risk prostate cancer
This trial tests using MRI and ultrasound together to guide freezing (cryoablation) treatment for prostate cancer. It may help target the tumor more precisely while avoiding areas that could cause side effects.
Miami Lakes, FloridaAges 55 years+ - NCT05241236Recruiting
Laser ablation guided by MRI and ultrasound for prostate cancer
This trial looks at a treatment that uses MRI and ultrasound to guide a laser to destroy prostate cancer. It may help men with low- or intermediate-risk prostate cancer who do not have spread beyond the prostate.
Miami Lakes, FloridaAges 50 years+ - NCT02669992Recruiting
Compare closure methods for a loop ileostomy after rectal cancer
This trial studies which technique works best to close a loop ileostomy after rectal cancer surgery. It compares different closure methods to see which is safer and more effective for patients.
GothenburgAges Any age - NCT04625556Recruiting
Urology cancer registry study using body microbiome data
This study builds a patient registry for prostate, kidney, bladder, and ureter cancers by analyzing your body’s microbiome (the microbes living in/ on the body). It may help doctors personalize care in the future, and your participation mainly involves allowing your medical and related information to be used for research.
SeoulAges 20 years+ - NCT05433935Recruiting
Study blood markers in pancreatic IPMN
This study looks for “biomarkers,” meaning measurable signs in the blood, in people diagnosed with intraductal papillary mucinous neoplasm (IPMN). It aims to better understand what changes happen in this condition and may help future diagnosis or monitoring.
Hangzhou, ZhejiangAges birth–90 years - NCT04813705RecruitingPhase 2
PET/CT-guided lower-dose radiation for nasopharyngeal cancer
This Phase 2 study tests whether using a special scan (PET/CT) to guide radiation can safely reduce the radiation dose for people with nasopharyngeal cancer. It may help lessen side effects while still treating the cancer effectively.
Taizhou, ZhejiangAges 18–80 - NCT04495790Recruiting
Cancer patient study to track health outcomes
This is an observational study that follows people with cancer to better understand outcomes over time. You may be asked to complete questionnaires and share information from your visits (in person or by video only if you meet their rules).
Seattle, WashingtonAges Any age - NCT04014530RecruitingPhase 1/Phase 2
Testing pembrolizumab plus ataluren for metastatic dMMR or pMMR cancer
This early-phase trial tests pembrolizumab combined with ataluren for people with metastatic colorectal cancer that has either dMMR or pMMR, and for metastatic dMMR endometrial cancer. The goal is to see whether this combination can shrink tumors or improve outcomes for cancers with specific mismatch repair (MMR) features.
Amsterdam, North HollandAges 18 years+ - NCT05501353Recruiting
Study tumor biomarkers in recurrent metastatic colon cancer
This study looks for blood/tumor signals (“biomarkers”) that may help predict outcomes in people whose colorectal cancer returns and spreads after surgery. It mainly helps researchers understand who may do better or worse, which can guide future care.
Hangzhou, ZhejiangAges 18–99 - NCT05707819Recruiting
Sintilimab plus chemoradiotherapy for high-risk nasopharyngeal cancer
This trial tests whether adding sintilimab (an immune treatment) to standard chemoradiotherapy can improve outcomes for people with high-risk, locally advanced nasopharyngeal (throat) cancer. It may help your immune system work better against the cancer alongside radiation and chemotherapy.
Nanning, GuangxiAges 18–70 - NCT02070328Recruiting
Proton therapy patient registry for outcomes and long-term follow-up
This study keeps a secure record of people receiving proton therapy to track outcomes over time. It may help researchers understand how proton therapy works in real life and improve future care.
Jacksonville, FloridaAges Any age - NCT05670938Recruiting
Follow-up after testicular cancer surgery and chemotherapy
This study looks at how people should be followed after treatment for testicular cancer (surgery and, for some, chemotherapy). It may help improve follow-up plans while keeping an eye out for cancer coming back.
Rotterdam, South HollandAges 18 years+ - NCT05713578RecruitingEarly Phase 1
Apantamide plus docetaxel with hormone therapy for advanced prostate cancer
This early-phase trial tests whether adding apantamide to hormone therapy (and possibly adding docetaxel chemotherapy) works better and is safe for men with high-volume spread of prostate cancer. It’s designed for people who have recently started hormone therapy and haven’t shown clear disease worsening yet.
Jinan, ShandongAges 18–90 - NCT01958762Recruiting
Cigarette buyers get oral cancer screening
This trial tests whether people who recently bought cigarettes can be offered screening for oral (mouth) cancer. It may help find cancer or warning changes earlier in people at higher risk from smoking.
