This study uses an AI model to predict how well chemotherapy will work before breast cancer surgery. It looks back at medical records and images from women who have already completed treatment to see if the AI can help guide future care.
Guangzhou, GuangdongAges Any age - NCT05890287Recruiting
Chidamide plus hormone therapy after chemotherapy for breast cancer
This trial studies chidamide added to standard hormone (endocrine) therapy to help prevent breast cancer from coming back after initial chemotherapy. It may help by keeping cancer under control for longer in people with HR-positive, HER2-negative breast cancer who respond to first-line treatment.
TianjinAges 18–75 - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Phoenix, ArizonaAges 18 years+ - NCT06910072Enrolling by invitationPhase 2/Phase 3
Chemo and immunotherapy before surgery for triple-negative breast cancer
This trial tests a combination of chemotherapy and two immunotherapy drugs given before surgery for women and men with triple-negative breast cancer. The goal is to see if this approach helps shrink or eliminate the tumor before surgery.
BeijingAges 18–75 - NCT07057791RecruitingPhase 2
Chemo plus immunotherapy for extensive-stage small cell lung cancer
This trial tests a combination of chemotherapy (platinum/etoposide) plus an immunotherapy drug (ivonescimab) for people with extensive-stage small cell lung cancer who have not received treatment before. The goal is to see if adding the immunotherapy improves outcomes.
Miami, FloridaAges 18 years+ - NCT07292246Recruiting
HandX-assisted endoscopic mastectomy study for breast cancer
