Pittsburgh, PennsylvaniaAges 18 years+ - NCT07289646RecruitingPhase 3
Lung perfusion scan to guide radiation planning for lung cancer
This study compares two ways of planning radiation treatment for lung tumors. One method uses a special scan to see which parts of your lungs work best, aiming to protect healthy lung tissue, while the other uses a standard anatomical approach. The goal is to see if the functional approach can reduce side effects and improve outcomes.
Brest, FinistèreAges 18 years+ - NCT04025164Recruiting
Shorter vs standard breast radiation after lumpectomy
This study compares a shorter course of radiation to a standard longer course after breast-conserving surgery (lumpectomy). It’s meant to see which schedule works just as well while focusing on safety and cancer control.
Guiyang, GuizhouAges 18–70 - NCT05059379RecruitingPhase 3
Different radiation fields after breast cancer surgery
This trial compares two ways of giving radiation to lymph node areas near the collarbone after surgery for invasive breast cancer. It aims to see which radiation approach works better and is safer for preventing cancer returning in these lymph nodes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05665920Recruiting
Shorter radiation after breast surgery for certain node-positive cancer
This trial compares a shorter, more concentrated radiation schedule versus a standard shorter schedule after breast-conserving surgery. It looks at whether the treatment works well and is safe, especially for women whose lymph nodes also need radiation.
São Paulo, São PauloAges 18 years+ - NCT05674305RecruitingPhase 3
Tested radiation alone vs added chemotherapy for EBV-negative after treatment
This Phase 3 trial compares giving radiation alone versus giving radiation at the same time as chemotherapy for nasopharyngeal cancer. It focuses on people whose EBV test becomes undetectable after one cycle of chemotherapy, to see which approach works best and is safest.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05768490RecruitingPhase 3
Radiation plus targeted pills for EGFR lung cancer brain spots
This Phase 3 study tests whether giving brain radiation early or later, along with almonertinib (a targeted pill), works better for people with EGFR-mutated non-small cell lung cancer that has a small number of brain metastases. It aims to control brain disease while checking safety and effectiveness in a carefully selected group.
Guangdong, GuangzhouAges 18–75 - NCT04583254RecruitingPhase 2
Shorter radiation plan for certain early cervical cancers
This trial tests a feasibility (“can it be done safely?”) approach that delivers radiation in a shorter schedule for some cervical cancer patients. It also uses weekly cisplatin chemotherapy and includes a radiation procedure called brachytherapy to improve treatment effectiveness.
Kelowna, British ColumbiaAges 18 years+ - NCT05884632Recruiting
Personalized daily radiation for prostate cancer after surgery
This trial studies a “daily adaptive” way of planning and delivering radiation after prostate surgery to treat prostate cancer that is coming back locally. It may help target the tumor more precisely while limiting radiation to healthy tissue.
Negrar, VeronaAges 18–80 - 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.
