Delayed vs immediate breast reconstruction after mastectomy and radiation
This study compares two timing options for rebuilding the breast after mastectomy followed by radiation: a reconstruction done later (delayed) versus one done sooner (delayed-immediate). The goal is to see which approach works better and is safer for recovery after treatment.
AabenraaAges 18 years+ - NCT03728673RecruitingPhase 2
Escitalopram for people with newly diagnosed grade 4 brain tumors
This trial studies whether escitalopram (an antidepressant medication) can help people with grade 4 glioma around the time they start standard cancer treatment. You may be screened especially for depression/anxiety status and medication history, because the study uses a specific mental-health medicine.
Omaha, NebraskaAges 19 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 - 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+ - NCT03735992Recruiting
Mind-body sessions for people with blood cancers in remission
This trial studies whether structured mind-body group sessions can support well-being and recovery for people whose blood cancer is in remission. It may be helpful if you can safely participate in group activities and are not currently receiving active cancer treatments.
StuttgartAges 18 years+ - NCT03736863RecruitingPhase 2
Testing combinations of medicines for advanced throat cancer
This trial tests a combination of medicines to treat advanced esophageal squamous cell carcinoma (throat/esophagus cancer) that cannot be removed by surgery and has spread or come back. It is for people whose first treatment (chemotherapy or immunotherapy) did not work well or was not tolerated.
Zhengzhou, HenanAges 18–75 - NCT03739411RecruitingPhase 1
MRI scan with a special agent to assess brain tumors
This Phase 1 study tests a new type of MRI scan using a special “hyperpolarized” imaging agent to help doctors diagnose glioma (a type of brain tumor). It’s mainly focused on whether the scan can safely and clearly show tumor-related information in people who may need treatment.
San Francisco, CaliforniaAges 19 years+ - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
Houston, TexasAges 18 years+ - NCT03740893RecruitingPhase 2
Test drug to block DNA damage in triple-negative breast cancer
This Phase 2 trial studies a treatment given around the time of breast surgery to help shrink or control residual (remaining) triple-negative breast cancer. It also checks biomarkers (lab signals) to understand who benefits, with some people receiving anti–PD-L1 immunotherapy and some not.
Bournemouth, DorsetAges 18 years+ - NCT03740503Recruiting
Study genes in people who respond unusually to treatment
This study looks at stored tumor samples to understand why some people respond much better or much worse than expected. The goal is to learn what the tumor’s genes might be telling doctors about response to treatment.
Toronto, OntarioAges 18 years+ - NCT03742687Recruiting
Testing a shorter, stronger radiation schedule for lung cancer
This trial studies a different way to deliver radiation to people with locally advanced, non-operable non-small cell lung cancer. It may help by aiming to treat the tumor effectively with a different radiation timing and dose pattern.
AarhusAges 18 years+ - NCT03745534Recruiting
Cochlear implant after Gamma Knife for vestibular schwannoma
This pilot study looks at how well cochlear implants work for hearing restoration in people who previously received Gamma Knife treatment for a tumor called vestibular schwannoma. It may help doctors understand what hearing results to expect after surgery.
Vienna, State of ViennaAges 18 years+ - NCT03747588Recruiting
Laparoscopic versus open surgery for pancreas cancer
This study compares two ways of doing pancreaticoduodenectomy (a major surgery to remove parts of the pancreas and nearby tissue): minimally invasive (often smaller incisions) versus open surgery. It may help clarify which approach works best when the cancer looks potentially removable.
Beijing, Beijing MunicipalityAges 18–75 - NCT03745560Recruiting
Test hearing testing during surgery to guide cochlear implant decisions
This study uses a special hearing test done during surgery for vestibular schwannoma to help decide what hearing treatment you need afterward. It may help guide whether a cochlear implant is a good option for hearing rehabilitation.
Vienna, AustriaAges 18–99 - NCT03747133Recruiting
Radiation treatment for certain kidney tumors
This trial tests a focused, high-dose radiation treatment (SABR) for kidney tumors that are too risky to remove with surgery or where surgery was declined. It may help shrink the tumor while limiting damage to surrounding tissue.
Toronto, OntarioAges 18 years+ - NCT03749980Recruiting
Study following people with von Hippel-Lindau (VHL)
This study follows people who have von Hippel-Lindau (VHL) over time to better understand how the condition changes. It may help doctors plan future treatments by collecting long-term health information.
Boston, MassachusettsAges Any age - NCT03748485Recruiting
Chemo after surgery for certain stage III colon cancer
This trial studies whether adding chemotherapy after surgery helps people with colon cancer that was diagnosed before surgery as stage III and later found to be without certain high-risk features. It may help lower the chance the cancer comes back, but you must meet specific surgery and health criteria.
Guangzhou, GuangdongAges 18–75 - NCT03750227RecruitingPhase 3
Radiation before or after brain tumor surgery
This study compares giving focused, high-precision radiation before or after surgery for brain metastases. It aims to see which timing works best to control tumors and improve outcomes.
Scottsdale, ArizonaAges 18 years+ - NCT03750513RecruitingPhase 1
Tested improved radiation targeting for children with ependymoma
This early-phase study tests a more precisely targeted type of radiation for children with ependymoma, aiming to treat the brain tumor more accurately. It may help reduce how much healthy tissue gets radiation, and researchers are checking safety and best dosing.
Boston, MassachusettsAges Up to 22 years - NCT03753243RecruitingPhase 2
Pembrolizumab and hormone blocker before prostate surgery
This Phase 2 trial studies whether pembrolizumab plus a hormone “androgen axis” blocker taken before prostate surgery can improve outcomes for people with high-risk, non-metastatic prostate cancer. It’s designed for patients who are planning prostate removal with an extended lymph node dissection.
Portland, OregonAges 18 years+ - NCT03758976Recruiting
Study of scans in advanced breast cancer recurrence
This study looks at people with advanced breast cancer to better understand recurrence by using information from recent scans. It may help researchers improve how advanced disease is assessed and followed over time.
LundAges 18 years+ - NCT03755739RecruitingPhase 2/Phase 3
Checkpoint cancer drug given into or near tumors
This trial studies whether giving immunotherapy “checkpoint inhibitor” medicine directly into the tumor area (and/or the artery feeding it), along with a chemotherapy-style drug, can work better for advanced solid tumors. It aims to boost the immune system’s ability to attack cancer while still being safe for people with measurable tumors.
Guanzhou, GuangdongAges 18 years+ - NCT03760575RecruitingPhase 1
Pembrolizumab plus chemo with surgery for pleural mesothelioma
This trial studies how well pembrolizumab (an immune therapy) works when added to chemotherapy before image-guided surgery for malignant pleural mesothelioma. It aims to shrink or control the cancer and improve surgical results by combining treatments.
Philadelphia, PennsylvaniaAges 18 years+ - NCT03759717Recruiting
Study of skull base tumors using tumor tissue
This study aims to learn more about skull base tumors by examining tumor tissue from surgery. It may help doctors better understand these tumors and improve future care.
