Duarte, CaliforniaAges 18 years+ - NCT07224152RecruitingPhase 1/Phase 2
NBTXR3 plus radiation for inoperable lung cancer
This trial tests a new drug called NBTXR3, which makes cancer cells more sensitive to radiation. You'll get one injection of NBTXR3 into your lung tumor, followed by standard radiation. It is for people with early-stage non-small cell lung cancer who cannot have surgery.
Houston, TexasAges 18 years+ - NCT07213154Recruiting
Optical scans for skin cancer diagnosis
This trial uses a special optical imaging scan to help diagnose skin cancer without needing a biopsy. It may be a good option if you have a suspicious skin lesion.
Atlanta, GeorgiaAges 18 years+ - NCT02992574Recruiting
Radiation after mastectomy for certain node-negative breast cancers
This trial studies whether giving radiotherapy after a mastectomy helps prevent breast cancer coming back in women whose lymph nodes are not involved (or only very tiny spread). It may help reduce recurrence risk, especially for patients with higher-risk features despite node-negative early cancer.
Chandigarh, ChandigarhAges 18–80 - NCT06406530Recruiting
Applying PRF gel before radiation for head and neck cancer
This trial tests whether applying a special gel made from your own blood (platelet-rich fibrin, or PRF) to the tooth sockets after extraction can help the gums heal better before radiation therapy starts. It's for people with head and neck cancer who need to have teeth removed on both sides of the jaw.
Giessen, HesseAges 18–99 - NCT06551857Recruiting
How cancer treatments affect hearing and thinking
This study looks at how common cancer treatments (certain chemotherapies and radiation to the head and neck) affect hearing in noisy places, thinking skills, and quality of life related to hearing. It aims to understand and possibly reduce these side effects.
Turku, Southwest FinlandAges 18–75 - NCT07195734RecruitingPhase 2
Adding chemo or immunotherapy before surgery for advanced head and neck cancer
This trial tests whether giving chemotherapy or chemotherapy plus immunotherapy before surgery can improve outcomes for people with advanced head and neck cancer that has come back or not gone away after prior treatment.
Tucson, ArizonaAges 18 years+ - NCT05903261Recruiting
Study of targeted radiation for rare cancers with limited spread
This observational study follows people with rare solid tumors and a limited number of metastases treated with a focused radiation technique (SBRT). Doctors want to see outcomes after using a strong, curative-intent radiation dose to all active spots.
Rozzano, MilanAges 18 years+ - NCT07170358Recruiting
Biomarker screening for head and neck cancer radiation therapy
This trial is looking for people with head and neck cancer who are about to start radiation therapy (possibly combined with other treatments). The goal is to find biomarkers that may help predict how well the treatment works or what side effects might occur.
Nanjing, JiangsuAges 18–75 - NCT07166042RecruitingPhase 3
Guided meditation during radiation for breast or gynecologic cancer
This study tests whether a guided meditation program during daily radiation therapy can help reduce stress and improve well-being for people with breast or gynecological cancer. You will be randomly assigned to either the meditation group or the usual care group.
Salt Lake City, UtahAges 18 years+ - NCT04375904RecruitingPhase 2
Stereotactic radiation for central lung tumors
This trial tests a precise, high-dose radiation treatment aimed at central lung tumors. It may help people who cannot have lung surgery and whose tumors can be safely targeted near sensitive organs.
DublinAges 18 years+ - NCT07162246RecruitingPhase 2
Radiosurgery for large brain tumors and metastases
This trial tests a special high-dose radiation treatment for people who have up to two large brain tumors (metastases) and possibly other smaller ones. The treatment aims to control the tumors while limiting radiation to healthy brain tissue.
Toronto, OntarioAges 18 years+ - NCT07150715RecruitingPhase 2
Radioactive drug plus precise radiation for recurrent prostate cancer
This trial tests a powerful radioactive drug (either alpha or beta) combined with precise radiation to treat prostate cancer that has come back in a few spots outside the prostate. It may help men whose cancer is still hormone-sensitive and has not spread widely.
