Lebanon, New HampshireAges 18–83 - NCT06404983Recruiting
Opioid-free anesthesia for breast cancer surgery
This study tests whether breast cancer surgery can be done safely without using opioid pain medicines during anesthesia. The goal is to see if avoiding opioids leads to fewer side effects and a smoother recovery.
Ioannina, EpirusAges 18–99 - NCT06409390RecruitingPhase 2
Sequential therapy based on tumor evolution for breast cancer
This trial tests a sequence of different treatments for breast cancer that has spread, based on how the cancer evolves. The goal is to find a personalized treatment plan that may work better over time.
Tampa, FloridaAges 18 years+ - NCT06380751RecruitingPhase 3
New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer
This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.
Gilbert, ArizonaAges 18 years+ - NCT06391749Enrolling by invitation
Blood test for multiple cancers in people with symptoms
This trial tests a new blood test (SPOT-MAS) that looks for signs of multiple cancers in people who already have symptoms and are being checked with imaging. If the blood test is positive, you'll get more detailed scans or a biopsy to see if cancer is present.
Ho Chi Minh CityAges 18 years+ - NCT02893761Recruiting
Bergonié Institute breast cancer database study
This study collects information from people who are receiving their first breast cancer treatment at the Bergonié Institute. It helps the institute better understand breast cancer care and outcomes over time.
BordeauxAges 18 years+ - NCT06260033RecruitingPhase 2
Radiation Therapy for Oligoprogressive ER+ Breast Cancer
This trial tests whether a precise radiation treatment (SBRT) can target a few growing spots of estrogen receptor-positive breast cancer that has spread to other parts of the body. It also uses a special PET scan (FES PET/CT) to see how well the cancer responds. The goal is to slow down the cancer and delay the need for stronger treatments.
