Shorter radiation before chemo and immunotherapy for rectal cancer
This trial tests a shorter course of radiation before chemotherapy and an immunotherapy drug to shrink mid-to-lower rectal cancer that has not spread. The goal is to improve treatment response and reduce side effects, potentially allowing for less invasive surgery.
Guangzhou, GuangdongAges 18–75 - NCT06954831RecruitingPhase 2
Short-course radiation for early-stage breast cancer
This trial tests a shorter, more intense radiation schedule for people with stage I-III breast cancer after lumpectomy. It aims to find if giving a higher daily dose over fewer sessions is safe and effective.
Arcadia, CaliforniaAges 40 years+ - NCT06953245Recruiting
Study of skin reactions from radiation in breast cancer patients
This study asks breast cancer patients about their skin reactions during radiation therapy. By sharing your experience, you can help doctors better understand and manage these side effects.
Rochester, MinnesotaAges 18 years+ - NCT06953076Recruiting
Ultrasound changes in fibroids during Relugolix treatment
This study tests whether an ultrasound can show how fibroids (benign uterine growths) change during treatment with a medication called Relugolix (combined with estrogen and progestin). It's for women who have heavy bleeding and want to know if the medication can shrink their fibroids.
RomaAges 18 years+ - NCT06183983Recruiting
Advanced MRI for better glioblastoma radiation
This trial tests whether using advanced MRI scans before radiation therapy can help doctors target the tumor more precisely and possibly improve outcomes for people with glioblastoma. It aims to make radiation treatment more personalized.
Rotterdam, South HollandAges 18 years+ - NCT05170503RecruitingPhase 2
Immunotherapy plus chemo before surgery for junction stomach cancers
This Phase 2 study tests giving immunotherapy together with chemotherapy before surgery for certain “locally advanced” cancers at the esophagus-stomach junction. It may help shrink the tumor and improve outcomes by treating the cancer earlier with both immune and chemotherapy approaches.
Guangzhou, GuangdongAges 18–75 - NCT05702944RecruitingPhase 4
Skipping pre-surgery blood pressure medicine for certain adrenal tumors
This trial studies whether it is safe to skip a specific pre-surgery blood pressure medicine (alpha-blocker) for people with normal blood pressure who have a pheochromocytoma or paraganglioma in one adrenal gland. It aims to see if fewer pre-op meds can still prevent risky blood pressure surges during surgery.
SeoulAges 19–70 - NCT05771181RecruitingPhase 2
Test vitamin E plus two cancer drugs for metastatic colon cancer
This trial tests whether adding vitamin E to two cancer medicines (fruityquintinib and tislelizumab) can work better in people with metastatic colorectal cancer that is mismatch-repair stable (MSS). It may help if your cancer has grown despite standard treatment, and you can meet the study’s safety and blood/organ requirements.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06309836Recruiting
Study of advanced basal cell carcinoma in patients
This study looks at how people with advanced basal cell carcinoma (a type of skin cancer that is hard to treat or has spread) are cared for and what happens over time. It does not test any new treatments, but helps doctors learn more about the disease.
Roma, ITAAges 18 years+ - NCT06334809Recruiting
Genetic test for men with prostate cancer and DNA repair changes
This trial looks for specific DNA repair changes in men with prostate cancer. It tests if these genetic features can help guide treatment decisions. You may join if you have high-risk localized, newly metastatic, or advanced prostate cancer and have tissue available for testing.
Candiolo, TurinAges 18 years+ - NCT06209099Recruiting
Organ preservation first for low-risk rectal cancer
This trial tests a strategy to avoid surgery by using watchful waiting after initial treatment for early-stage rectal cancer. It may help patients keep their rectum and avoid a permanent colostomy.
Beijing, Haidian DistrictAges 18–85 - NCT05740033Recruiting
Closing the radial forearm donor site after mouth surgery
This study looks at how best to close the skin area on the forearm after surgeons take tissue to rebuild part of the mouth. If you need a radial forearm tissue reconstruction, you may be asked about outcomes afterward using English questionnaires.
Vancouver, British ColumbiaAges 18 years+ - NCT05765877RecruitingPhase 2
Study drug before surgery for ALK or ROS1 lung cancer
This Phase 2 trial tests WX-0593 given before surgery for certain types of lung cancer that have ALK or ROS1 gene changes. The goal is to shrink or control the cancer ahead of the operation and see how well the treatment works and is tolerated.
Jinan, ShandongAges 18 years+ - NCT06409702RecruitingPhase 4
Treating high-risk multiple myeloma with MRD testing
This trial tests a treatment plan for people with newly diagnosed high-risk multiple myeloma. It uses a special test called minimal residual disease (MRD) detection to see how well the treatment is working and guide next steps.
Suzhou, JiangsuAges 18 years+ - NCT06418412Recruiting
Pan-Asian study for EGFR exon 20 insertion lung cancer
This trial is building a large database of lung cancer patients from Asia who have a specific EGFR mutation (exon 20 insertion). Your medical records and treatment information will be collected to help doctors learn more about this type of cancer and improve care.
SingaporeAges 21–99 - NCT06906705Recruiting
Ultrasound to Check Lymph Nodes During Gynecological Cancer Surgery
This study uses a special ultrasound probe during surgery to check lymph nodes for cancer. It aims to see if this tool can help doctors make better decisions during your gynecological cancer surgery without needing extra tests.
RomaAges 18–99 - NCT05613452RecruitingPhase 2
Carbon ion radiation for peripheral lung cancer you can’t operate on
This trial tests whether carbon ion radiation (high-energy targeted radiation) can control peripheral non-small cell lung cancer in people who are medically unable to have surgery. It may help shrink or stop tumor growth while limiting harm to nearby organs.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT02328677Recruiting
Colorectal cancer study for newly diagnosed patients
This study enrolls people newly diagnosed with colon or rectal cancer to learn about their care and outcomes. You might be able to join if you meet the age, language, and consent requirements.
Los Angeles, CaliforniaAges 18–89 - NCT05253495RecruitingPhase 2
Targeted immunotherapy added to chemotherapy and radiation for lymphoma
This Phase 2 trial tests whether adding targeted immunotherapy to standard chemotherapy and radiation can improve outcomes in children with certain types of lymphoma. It may help the immune system work better against cancer.
Birmingham, AlabamaAges 3–39 - NCT06942286Enrolling by invitation
HPV self-testing for cervical cancer screening in Indonesia
This study tests a home-based HPV self-collection kit for women who haven't been screened recently. The goal is to find cervical pre-cancer early, so treatment can prevent cancer.
Lebak, BantenAges 30–69 - NCT05844514Recruiting
Breath test study for colorectal cancer detection and risk
This study tests a breath analysis (a sample you give by breathing into a device) to help detect or better understand colorectal cancer. It may help researchers see whether breath results can identify cancer sooner and in people who haven’t started treatment yet.
LondonAges 18 years+ - NCT06326957Recruiting
Online program for chronic breathlessness
This trial tests an internet-based self-guided program to help adults with chronic breathlessness. It is designed for people who still feel short of breath despite treatment for conditions like COPD, lung disease, or cancer.
LondonAges 18–110 - NCT06186726RecruitingPhase 2
Carbon ion radiation with chemo for thymic cancer
This trial tests a new type of radiation (carbon ion) plus chemotherapy for thymic tumors that cannot be removed with surgery. It aims to see if this combination can effectively treat the cancer while protecting healthy organs.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06311981RecruitingPhase 2
Carbon ion radiation for elderly lung cancer patients
This trial tests carbon ion radiotherapy for adults 75 and older with locally advanced non-small cell lung cancer who cannot have surgery. The goal is to see if this precise type of radiation can treat the cancer effectively with fewer side effects.
