Recruiting studies
- NCT03712774Recruiting
Study of how chemoradiation affects quality of life
This observational study follows people with esophageal cancer to see how their quality of life changes after chemoradiation. It does not change your treatment, but it may help doctors better understand what to expect during and after therapy.
Munich, BavariaAges 18 years+ - NCT01194648Recruiting
HIFU treatment for early prostate cancer
This trial studies a focused ultrasound treatment called HIFU for prostate cancer that appears limited to the early stages. It aims to treat cancer within the prostate while avoiding treatment spread to lymph nodes or distant organs.
London, EnglandAges Up to 90 years - NCT03731442RecruitingPhase 3
Radiation plus chemotherapy for esophageal cancer that came back
This Phase 3 trial studies giving combined chemotherapy and radiation to treat esophageal cancer that has returned after earlier surgery and/or prior treatments. It may help control the cancer in the area where it comes back, especially when the surgical margins were not fully clear or the cancer is outside the original radiation field.
Beijing, Beijing MunicipalityAges 16–70 - NCT03792854Recruiting
Quality-of-life study after standard treatment for anal cancer
This observational study follows people with anal cancer to understand how their quality of life changes after they receive standard chemoradiation therapy. It may help doctors better support patients with symptoms, recovery, and daily functioning over time.
Munich, BavariaAges 18 years+ - NCT03498326RecruitingPhase 2
Gemcitabine plus celecoxib after pancreatic surgery
This trial tests whether adding celecoxib to gemcitabine chemotherapy after complete (R0) pancreatic tumor removal can lower the chance the cancer comes back. It may help people who have had successful surgery but still need anti-cancer treatment.
Hangzhou, ZhejiangAges 18–90 - NCT03064646Recruiting
Preserving tissue in near-complete rectal cancer response
This trial studies whether it’s safe to preserve the rectum (instead of removing it right away) for people with locally advanced rectal cancer who respond very well after pre-treatment radiation and/or chemotherapy. It may help some patients avoid major surgery, but eligibility depends on response seen on exam, scope, and MRI, and on having no spread to distant organs.
Elche, AlicanteAges 18 years+ - NCT03687151Recruiting
Cancer registry for people living in a specific French region
This study helps build a population-wide cancer observatory (a real-world cancer record) for people in a specific region of France. It may help researchers better understand cancer patterns and needs in the area.
NiceAges Any age - NCT03731130Recruiting
Study on quality of life after rectal cancer treatment and surgery
This observational study follows people with rectal cancer who get radiation (with or without chemotherapy) before surgery. It aims to understand how these treatments affect quality of life after surgery.
Munich, BavariaAges 18 years+ - NCT03781531Recruiting
Blood tests to find hidden cancer after a blood clot
This study looks for “biomarkers,” or blood signs, that may help detect hidden (occult) cancer in people who recently had a blood clot in the leg or a lung clot. It may help doctors catch cancer earlier by improving detection after venous thromboembolism.
StockholmAges 18 years+ - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.
Guangzhou, GuangdongAges 18–75 - NCT03385018Recruiting
Laparoscopic total stomach surgery trial for stomach cancer
This trial studies whether a minimally invasive (laparoscopic) removal of the entire stomach, along with lymph node removal, can be done safely and effectively for certain stomach cancers. It may be an option if your cancer is in the stomach, has limited spread to nearby lymph nodes, and can be fully removed.
SeoulAges 20–80 - NCT02971085Recruiting
Registry for prostate cancer on active surveillance
This study follows men with low-risk prostate cancer who choose active surveillance (watching closely instead of immediate treatment). It aims to better track which monitoring results stay reassuring over time, and when treatment might be needed.
SeoulAges 40–80 - NCT03925662RecruitingPhase 3
Mebendazole added to stage 4 colon cancer care
This trial studies whether adding mebendazole (an existing anti-parasite medicine) to standard treatment can improve outcomes for people with stage 4 colon cancer. You might qualify if you have stage 4 colorectal cancer and none of the key safety concerns.
CairoAges 18 years+ - NCT03961373RecruitingPhase 3
Standard vs longer lymph node surgery after chemo for stomach cancer
This study compares two surgical approaches to remove lymph nodes after you’ve already had chemotherapy for stomach cancer. It aims to see whether removing lymph nodes in a more extended way improves outcomes without causing unacceptable side effects.
SienaAges 18–80 - NCT03941561RecruitingPhase 3
Shorter versus longer chemotherapy for stage II stomach cancer
This trial compares two lengths of an oral chemotherapy medicine (9 months vs 1 year) after surgery for stage II stomach cancer. It aims to see which schedule works better and is easier to complete, while checking safety for people without major health problems.
AnqingAges 18–75 - NCT02724670Recruiting
MRI-guided radiation for prostate cancer patients
This study tests radiation treatment planned and guided using MRI scans (“image-guided radiotherapy”) for men with prostate cancer who are aiming for a cure. If you qualify, you may receive radiation with more precise targeting using MRI to help deliver treatment accurately.
TübingenAges 18 years+ - NCT04063527RecruitingPhase 3
Stage I ovarian cancer treatment after surgery
This trial studies whether an additional treatment after surgery can help people with early-stage epithelial ovarian cancer live longer and stay well for more time. It is meant for patients who had a detailed staging operation and are able to start treatment within 8 weeks.
Nagakute-shi, Aichi-kenAges 20 years+ - NCT04086290RecruitingPhase 1/Phase 2
Surgery plus targeted radiation for prostate cancer spread
This study looks at whether combining prostate surgery with a highly focused radiation treatment (SBRT) can control prostate cancer that has spread to a limited number of bones. It may help patients by treating the main tumor and the specific metastatic spots in a controlled way.
HerlevAges 18 years+ - NCT04158843Recruiting
Local surgery vs comfort treatment for limited breast cancer spread
This trial compares a more direct local treatment (targeting a small, limited spot) versus a comfort-focused palliative approach for breast cancer that has spread only to one side of the upper arm bone or breastbone area. It aims to see which approach works better while keeping side effects manageable.
Hangzhou, ZhejiangAges 18–75 - NCT04281641Recruiting
Testing marker-guided treatment before surgery for HER2-positive breast cancer
This trial studies how well a HER2-focused treatment plan works before surgery (“neoadjuvant” therapy) for operable HER2-positive breast cancer. It also uses tumor tissue tests to find markers that may predict who benefits most.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT03294889RecruitingPhase 1/Phase 2
Single-dose SBRT for early prostate cancer
This trial tests a very short, one-time form of radiation (SBRT) to treat prostate cancer. It aims to see whether treating the prostate in one shot is safe and effective for carefully selected patients.
GenevaAges 18–85 - NCT04437160RecruitingPhase 2
Chemo after surgery for triple-negative breast cancer with leftover tumor
This Phase 2 study tests chemotherapy given after surgery for people with triple-negative breast cancer who still have cancer left after initial (neoadjuvant) chemo. It may help lower the chance the cancer comes back in people at higher risk based on leftover tumor and lymph node findings.
Beijing, Beijing MunicipalityAges 18–75 - NCT04453904Recruiting
Testing best added chemo and radiation after stage III uterine cancer
This study compares different ways of giving radiation and chemotherapy after surgery for stage III endometrial (uterine) cancer. It aims to find which approach works best to reduce cancer risk and improve outcomes.
Beijing, Beijing MunicipalityAges Any age - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer
This trial studies whether adding camrelizumab (an immunotherapy drug) to radiation can improve outcomes and be safe for people with early triple-negative breast cancer. It is designed for specific early-stage cases after breast surgery, using tumor and blood tests to match the cancer’s features.
