Proton vs photon radiation for anal canal cancer
This study compares two types of radiation—protons versus photons—for anal canal squamous cell carcinoma. It may help find which option delivers treatment more effectively or with fewer side effects.
GothenburgAges 18 years+ - NCT04464122Recruiting
Testing blood markers to diagnose and gauge early response in NEN
This trial studies whether specific blood “biomarkers” can help confirm a type of cancer called NEN (neuroendocrine neoplasm) and show whether treatment is working early. It may help doctors start or adjust treatment sooner, especially for cancers that are advanced or have spread.
Rome, ItalyAges 18–80 - NCT04463316Recruiting
Clinic study for people with rare genetic conditions
This study is for people who have a rare syndrome or rare congenital condition and are seen at a rare-disease clinic. It aims to better understand these conditions and how care works in a team setting, which may help guide future treatment decisions.
Rotterdam, South HollandAges 18 years+ - NCT04466059Recruiting
AI tool for leukemia diagnosis using blood or marrow samples
This study tests whether an AI (computer system) can help improve leukemia and related blood cancer diagnoses. You may be able to help if your doctor is already evaluating you for a possible blood disorder and your sample is high enough quality for testing.
Munich, BavariaAges 18 years+ - NCT04467723RecruitingPhase 1/Phase 2
Atezolizumab plus pirfenidone for advanced lung cancer
This Phase 1/2 trial tests whether combining atezolizumab and pirfenidone can help people with non-small cell lung cancer (NSCLC) after prior treatment. It is aimed at patients whose cancer has certain genetic markers ruled out and who can safely take study medicines and follow frequent visits.
Fairway, KansasAges 18 years+ - NCT04468061RecruitingPhase 2
Study chemo drug plus immunotherapy for metastatic triple-negative breast cancer
This trial tests sacituzumab govitecan (an antibody-drug medicine) with or without pembrolizumab (an immune-system therapy) in people with metastatic triple-negative breast cancer. It may help by shrinking tumors and improving immune control, especially for patients with specific tumor marker results.
Stamford, ConnecticutAges 18 years+ - NCT04469296Recruiting
Diet changes before surgery for hormone-receptor breast cancer
This trial tests whether changing your diet before your breast surgery can help people with early, hormone-receptor (ER/PR+) breast cancer. It focuses on patients who have not started treatment yet and want to keep surgery as the main treatment.
Montpellier, HeraultAges 18–80 - NCT04471987RecruitingPhase 1
IL-12 drug for metastatic cancer after checkpoint therapy
This Phase 1 trial studies the safety of an investigational drug called IL-12-L19L19 and looks for early signs it may help control advanced (metastatic) solid tumors. It is designed for people whose cancer has continued to grow even after treatment with immune “checkpoint” therapies.
Hamburg, Free and Hanseatic City of HamburgAges 18–80 - NCT04472338Recruiting
Prostate cancer screening for people with higher genetic risk
This study looks at prostate cancer screening for people who may be at higher risk because of a specific inherited (genetic) change. It may help your care team find the best screening approach to catch aggressive prostate cancer earlier.
Duarte, CaliforniaAges 40 years+ - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT04473794Recruiting
Testing ways to assess pancreatic cyst risk and progression
This study looks at patients who have been referred for evaluation of a pancreatic cyst. It aims to improve how doctors estimate risk and predict how cysts may change over time.
Baltimore, MarylandAges 18 years+ - NCT04473833Recruiting
Transvaginal ultrasound screening for ovarian cancer risk
This study tests whether a transvaginal ultrasound can be used as a screening tool for ovarian cancer in women at higher risk. It may help find ovarian cancer earlier in people who have a strong family or personal cancer history.
Lexington, KentuckyAges 24 years+ - NCT04475354Recruiting
Questionnaire study of distress in cervical cancer patients and partners
This study asks newly diagnosed cervical cancer patients and their partners to complete questionnaires about distress (emotional stress and worry). It may help researchers understand how distress affects both patients and partners and what support could be most helpful.
BredaAges 18 years+ - NCT04474301Recruiting
Quality of life check for people with melanoma during COVID-19
This study looks at how people with melanoma are feeling during the COVID-19 pandemic, including quality of life. You may be asked to share information through surveys or study contact so the researchers can understand needs and concerns.

Radiotherapy plus chemo for WNT medulloblastoma in children
This study tests whether adding a specific brain/spinal radiation plan (focused radiation plus low-dose spinal coverage) followed by chemotherapy works well for children with newly diagnosed WNT medulloblastoma after surgery. It targets kids whose remaining tumor after surgery is small and who have no spread to the spine or fluid.
Mumbai, MaharashtraAges 3–16 - NCT04475705RecruitingPhase 4
Propofol or sevoflurane for anesthesia in child tumor surgery
This trial compares two types of anesthesia medicine—propofol versus sevoflurane—during planned surgery to remove a solid tumor. It aims to find which option is safer and works better for children having curative tumor surgery.
