BrusselsAges 18–39 - NCT04677205Recruiting
Tumor-to-lymph-node study after lung cancer surgery
This study looks at molecular (biologic) signals in the tumor and nearby lymph nodes after curative surgery for stage IIIA lung cancer. It may help doctors better understand the disease and improve future treatment planning.
BordeauxAges 18 years+ - NCT04501523RecruitingPhase 2
ctDNA-guided immunotherapy boost after chemotherapy for triple-negative breast cancer
This Phase 2 study checks whether a blood test that looks for cancer DNA (ctDNA) can help decide who should get an extra 12-month immunotherapy treatment after standard chemotherapy and surgery. It may help reduce the chance of the cancer coming back in people with triple-negative breast cancer.
Guandong, GuangdongAges 18–80 - NCT04803539RecruitingPhase 2/Phase 3
ctDNA-guided booster treatment after chemo for triple-negative breast cancer
This trial uses a blood test called ctDNA to see who is at higher risk after surgery and standard chemotherapy for triple-negative breast cancer. If your ctDNA test is positive, you may receive an extra “boost” treatment to help reduce the chance the cancer returns.
Guandong, GuangdongAges 18–80 - NCT06165900RecruitingPhase 2
Radiation plus immunotherapy and chemo before surgery for triple-negative breast cancer
This trial tests combining stereotactic radiation therapy with immunotherapy (adebrelimab) and chemotherapy (nab-paclitaxel and carboplatin) before surgery for early or locally advanced triple-negative breast cancer. The goal is to see if this combination improves treatment response.
Shenyang, LiaoningAges 18–75 - NCT05760378RecruitingPhase 3
Famitinib plus immunotherapy for advanced triple-negative breast cancer
This Phase 3 trial tests a combination of famitinib (a cancer drug that targets blood vessel growth) with immunotherapy drugs in people with newly diagnosed advanced triple-negative breast cancer that has spread or cannot be fully removed. It aims to improve how long patients live and how well the cancer responds.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06314906RecruitingPhase 3
Acupuncture plus anti-nausea drugs for breast cancer chemo side effects
This trial tests whether adding electroacupuncture (a type of acupuncture with mild electrical pulses) to standard anti-nausea medicine can better prevent nausea and vomiting caused by strong chemotherapy. It is for people with early-stage breast cancer who are about to start a very strong chemotherapy regimen.
Lanzhou, GansuAges 18–75 - NCT06214598Recruiting
Anti-inflammatory diet for breast cancer patients on hormone therapy
This study tests whether a special anti-inflammatory diet can help reduce side effects in breast cancer survivors who are taking aromatase inhibitors after menopause. You would be randomly assigned to either follow the diet for 6 months or continue your usual diet, and your health will be monitored.
BelgradeAges 45–70 - NCT07789717Recruiting
Acupuncture for joint pain from breast cancer hormone therapy
This study tests whether acupuncture (with medication injection at specific points) can reduce joint pain caused by aromatase inhibitors, which are common breast cancer hormone therapies. If you have such pain, you may be able to join.
Daejeon, DaejeonAges 19–75 - NCT07708571Recruiting
Coaching program for women on ribociclib and aromatase inhibitor
This study tests whether a coaching program based on personality types helps women with early-stage hormone receptor-positive, HER2-negative breast cancer stick to their treatment plan. Participants must be taking ribociclib (Kisqali) and an aromatase inhibitor, and their cancer must not have spread to other organs.
Augsburg, BavariaAges 18 years+ - NCT05725265Recruiting
Low-level laser treatment for arm swelling after breast cancer
This study tests whether low-level laser therapy can safely reduce swelling in one arm caused by breast-cancer treatment. It compares the laser to a look-alike inactive (placebo) treatment and checks changes over time.
TaipeiAges 20 years+ - NCT07677839Recruiting
Study using ultrasound to look at normal lymph nodes before breast surgery
This study uses a special type of ultrasound (UHFUS) to take detailed images of your lymph nodes before and during breast cancer surgery. The goal is to better understand normal lymph node anatomy, which may help prevent lymphedema (swelling) after surgery.
Sacramento, CaliforniaAges 18 years+ - NCT06533384RecruitingPhase 3
PARP inhibitor or chemo plus immunotherapy after surgery for high-risk TNBC
This trial tests whether adding a PARP inhibitor or capecitabine (chemo) to a PD-1 inhibitor (immunotherapy) after surgery helps prevent triple-negative breast cancer from coming back. It's for people with high-risk disease who have completed initial treatment.
Guangzhou, GuangdongAges 18–70 - NCT05217966Recruiting
Radiation before possible breast surgery for early ER-positive cancer
This study gives radiation to the breast before surgery to see if some people can safely delay or even skip surgery. It targets women with a small, node-negative, ER-positive breast cancer with low genetic risk.
Montreal, QuebecAges 50 years+ - NCT06692725Recruiting
Lighter chemo with immunotherapy for triple-negative breast cancer
This trial tests whether using less chemotherapy combined with immunotherapy before surgery works well for people with stage II or III triple-negative breast cancer. The goal is to reduce side effects while still being effective.
Beijing, Beijing MunicipalityAges Any age - NCT06700369Recruiting
Lowering chemo with targeted therapy for HER2+ breast cancer
This study looks at whether using targeted therapy can reduce the amount of chemotherapy needed before surgery for HER2-positive breast cancer. It aims to find a safer, equally effective treatment plan.
Beijing, Beijing MunicipalityAges Any age - NCT06700382Recruiting
Capecitabine for TNBC after incomplete response
This trial looks at different ways to use the chemotherapy drug capecitabine for people with triple-negative breast cancer who still have cancer cells after initial treatment and surgery. It aims to find the best approach to improve outcomes.
Beijing, Beijing MunicipalityAges Any age - NCT06007027Recruiting
Vaginal laser therapy for breast cancer survivors with menopause symptoms
This trial tests whether a vaginal laser treatment can help breast cancer survivors who have menopause-like symptoms such as vaginal dryness or pain during sex. It is designed for women currently on hormone-blocking therapy.
RandersAges 18–100 - NCT06722599Recruiting
Shorter chemo with targeted drugs for low-risk HER2 breast cancer
This trial tests whether a short course of chemo plus two targeted drugs (trastuzumab and pertuzumab) before surgery works well for people with early-stage, low-risk HER2-positive breast cancer. It may help reduce the need for stronger chemo later.
Beijing, Beijing MunicipalityAges Any age - NCT06703567Recruiting
Helping patients understand gene test results for breast cancer
This study tests a tool to help people newly diagnosed with early-stage breast cancer better understand their gene test results. It is for patients who haven't yet decided about chemotherapy and want to learn more about their options.
MilanAges 18 years+ - NCT07548762Recruiting
Skin-Sparing vs. Standard Mastectomy for Breast Cancer
This study compares two surgical approaches to remove breast cancer: one that preserves more of the skin (skin-sparing) versus a standard approach. The goal is to see which method results in fewer wound-healing problems after surgery.
Guangzhou, GuangdongAges 18–75 - NCT07528716RecruitingPhase 3
AI-guided treatment for HER2-positive breast cancer
This trial tests whether an artificial intelligence model can help doctors choose the best targeted therapy before surgery for HER2-positive breast cancer (a type of breast cancer with a protein called HER2). The goal is to improve how well the treatment works and reduce side effects.
ShanghaiAges 18–75 - NCT06754059Recruiting
Pyrotinib with trastuzumab for HER2-positive breast cancer maintenance
This trial tests a combination of two targeted drugs (pyrotinib and trastuzumab) as maintenance therapy to keep HER2-positive breast cancer that has spread under control. It is for women who have already received some first-line treatment and are stable enough to continue therapy.
