Surgery for HPV-related oropharyngeal cancer
This trial is testing a surgical approach for people with HPV-related oropharyngeal cancer that is stage I or II (but not the very smallest). The goal is to see if removing the tumor through the mouth and taking out neck lymph nodes is effective and safe. It may be an option if you are healthy enough for surgery.
St Louis, MissouriAges 18 years+ - NCT06704555RecruitingPhase 2
Radiation plus drug combo for untreated bulky follicular lymphoma
This trial tests a combination of radiation, an immunotherapy drug (tislelizumab), and chemotherapy (RCHOP) for people with previously untreated bulky follicular lymphoma. It aims to see if giving radiation first followed by the drug combo can improve outcomes for larger tumors.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT06704659Recruiting
Repeated radiation for recurrent breast cancer
This study tests giving a second round of radiation therapy to women whose breast cancer has come back in the same breast, at least 3 years after their first radiation. It may be an option for women 55 and older who have a small, local recurrence that can be removed with surgery.
HelsinkiAges 55 years+ - NCT06739655Recruiting
Radiation before surgery with breast reconstruction
This trial tests whether giving radiation therapy before surgery (instead of after) is safe and effective for women with breast cancer who also want immediate breast reconstruction. It could help avoid the need for a second surgery and improve recovery.
Edegem, AntwerpenAges 18 years+ - NCT06769126RecruitingPhase 2
Personalized treatment study for extensive stage small cell lung cancer
This study uses biomarker tests on your tumor to find a personalized treatment after initial chemotherapy. You will be assigned to one of four treatment groups based on your biomarker results.
Loma Linda, CaliforniaAges 18 years+ - NCT06780787RecruitingPhase 2
Study of chemo plus immunotherapy for localized rectal cancer before surgery
This trial tests a combination of chemotherapy (FOLFOX) and two immunotherapies (botensilimab and balstilimab) before surgery for patients with localized rectal cancer. It aims to see if adding immunotherapy helps shrink the tumor and improve outcomes.
Duarte, CaliforniaAges 18 years+ - NCT06867484Recruiting
Breast re-irradiation after second lumpectomy
This trial tests whether giving a second round of radiation to the breast after a lumpectomy for a recurrence is safe and effective. It is for people with a specific type of breast cancer (ER+HER2-) who meet strict criteria regarding prior radiation and tumor characteristics.
Boca Raton, FloridaAges 40 years+ - NCT06902311RecruitingPhase 2
Shorter radiation after lumpectomy for early breast cancer
This trial tests a shorter, more intense course of daily radiation therapy (called ultra hypo-fractionation) given after lumpectomy for early-stage breast cancer. The goal is to reduce the number of treatment visits while keeping the same high level of effectiveness and safety.
Chapel Hill, North CarolinaAges 50 years+ - NCT06905132RecruitingPhase 2
Short radiation before surgery for soft tissue sarcoma
This study tests a 5-day course of radiation before surgery instead of the usual 5 weeks. It may help people who face challenges like travel or tumor growth that make the longer schedule difficult.
Charleston, South CarolinaAges 18 years+ - NCT06936748RecruitingPhase 2
Radiation plus immunotherapy for large relapsed solid tumors
This trial tests a new combination of radiation therapy and two immunotherapy drugs (Iparomlimab and Tuvonralimab) for people whose solid tumors have returned or spread and are too large for standard surgery. The goal is to shrink the tumor and control the cancer.
Nanchang, JiangxiAges 18–75 - NCT06940180RecruitingPhase 2
Immunotherapy and chemotherapy before surgery for sinus cancer
This trial tests a combination of an immunotherapy drug (toripalimab) plus chemotherapy before surgery for sinus cancer that has not spread. The goal is to see if this treatment shrinks the tumor so surgery can be more effective.
Boston, MassachusettsAges 18 years+ - NCT06954623Recruiting
Partial breast re-irradiation for breast cancer recurrence
This trial tests a second round of radiation to just part of the breast for women who had a previous lumpectomy and radiation, and now have a small, early-stage cancer or DCIS in the same breast. The goal is to see if a focused re-treatment is safe and effective.
HeidelbergAges 18 years+ - NCT06971211RecruitingPhase 2
Radiation and drug combo for advanced prostate cancer
This trial combines radiation therapy with two drugs (fluzopanib and abiraterone acetate) to treat men with metastatic castration-resistant prostate cancer that hasn't been treated yet. The goal is to see if this triple approach helps slow the cancer's growth.
Shenyang, LiaoningAges 18 years+ - NCT06984250Recruiting
