BudapestAges 18–65 - NCT07855627Recruiting
Predicting lymphedema risk before surgery
This study looks at whether a simple measurement taken before surgery can help predict if you might develop lymphedema (arm swelling) after treatment. It is for women with newly diagnosed inflammatory breast cancer who are planning to have standard treatments.
Houston, TexasAges 18 years+ - NCT04371913Recruiting
Second chance breast-conserving treatment for certain breast recurrences
This trial studies a personalized plan to remove and re-treat a limited breast recurrence while trying to keep the breast. It may help people whose cancer came back in the same breast after prior breast-conserving treatment, with certain size and spread limits.
Brooklyn, New YorkAges 19–90 - NCT06382818Recruiting
Personalized breast radiation based on risk and side effects
This trial tests whether radiation therapy can be personalized based on your risk of the cancer coming back and your risk of side effects from radiation. Depending on those factors, you may receive a tailored radiation plan that could be more or less intense.
MontpellierAges 18 years+ - NCT04710797Recruiting
Lymph node surgery for early-stage ovarian cancer
This trial studies whether removing (dissecting) lymph nodes during surgery can improve care for people with early-stage ovarian cancer that still needs chemotherapy. You may be eligible if you have certain ovarian cancer types and your scans and surgery do not show clearly suspicious lymph nodes.
Guangzhou, GuangdongAges 18–70 - NCT07361562RecruitingPhase 1
Study of CGT4255 for advanced solid tumors with HER2 changes
This trial tests an oral drug called CGT4255 for people with advanced solid tumors that have certain changes in the HER2 gene or related proteins. It aims to see if the drug is safe and effective.
Scottsdale, ArizonaAges 18 years+ - NCT06556654Recruiting
Tissue reinforcement for breast reconstruction study (REDEFINE)

Scottsdale, ArizonaAges 22 years+ - NCT07650305Recruiting
Pain Relief Methods After Breast Cancer Surgery
This trial compares two different nerve-blocking techniques (numbing methods) to reduce pain after breast cancer surgery. Both approaches aim to keep you comfortable during and after your operation.
CairoAges 18–65 - NCT07187726Recruiting
Trial to predict arm swelling risk during breast cancer radiation
This trial checks if telling you about your personal risk of arm swelling (based on a computer prediction) helps prevent it. You'll wear a compression sleeve during radiation and be monitored closely.
ArrasAges 18 years+ - NCT06022029RecruitingPhase 1
Study of injected ONM-501 alone or with cemiplimab for advanced cancers
This trial tests an injected study drug (ONM-501) alone or with another drug (cemiplimab) for people with advanced solid tumors or lymphomas that haven't responded to other treatments. It aims to find a safe dose and see if the combination helps shrink or control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06888258Recruiting
Comparing two nerve blocks for pain after breast cancer surgery
This study compares two types of nerve blocks for pain relief after breast cancer surgery. It will help determine which block works better to reduce pain and the need for strong pain medicines after a mastectomy.
CairoAges 18–60 - NCT06033287Recruiting
Real-world study of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well CDK4/6 inhibitors combined with hormone therapy work in real-world settings for people with a certain type of advanced breast cancer (HR+/HER2-). It aims to understand the best treatment path and what happens next.
Changsha, HunanAges 18 years+ - NCT02743858Recruiting
Watch swelling study after breast lymph node surgery
This study looks at how and when swelling (lymphedema) happens after breast cancer surgery on the armpit lymph nodes. You may be followed closely after your planned one-sided procedure to better understand who gets swelling and how it changes over time.
Basking Ridge, New JerseyAges 18 years+ - NCT05255471RecruitingPhase 3
Olaparib after surgery for recurrent ovarian cancer
This trial tests whether olaparib (a pill cancer medicine) works better than standard platinum chemotherapy after a second surgery for recurrent ovarian cancer. It’s for people whose cancer returned after initial PARP-inhibitor (PARPi) maintenance and aims to see if treatment can control the cancer for longer with acceptable side effects.
NaplesAges 18 years+ - NCT07738770Recruiting
Comparing two numbing techniques for pain relief after mastectomy
This trial tests two different numbing injections to see which one works better for pain after breast cancer surgery. If you are having a mastectomy, you may be able to join and help find a better way to manage pain.
Jakarta, DKI JakartaAges 18–60 - NCT05361837Recruiting
Nerve block with sedation for breast surgery comfort
This trial tests if adding a numbing injection (serratus anterior plane block) with a calming medicine (dexmedetomidine) helps reduce pain during and after breast removal surgery.
Cairo, Cairo GovernorateAges 18–65 - NCT07436663RecruitingPhase 4
Preventing heart damage from breast cancer chemotherapy with two diabetes drugs
This trial tests whether two different diabetes drugs (SGLT-2 inhibitors and DPP-4 inhibitors) can help prevent heart damage that anthracycline chemotherapy can cause in breast cancer patients. You would receive one of the two drugs during your treatment to see if it protects your heart.
Tanta, ElgharbeyaAges Any age - NCT03561740RecruitingPhase 3
Capecitabine plus usual treatment for high-risk HER2 breast cancer
This trial looks at whether adding a chemotherapy medicine called capecitabine (taken in smaller, regular doses) to the standard after-surgery (adjuvant) treatment can lower the chance of cancer coming back in people with early-stage, high-risk HER2-positive breast cancer. It targets patients who still had cancer left after earlier treatment or who had higher-risk tumor features.
Guangzhou, GuangdongAges 18–70 - NCT04072653Recruiting
Sentinel node biopsy versus watchful waiting after PET
This trial studies whether taking a sample from the sentinel lymph node (a first lymph node that can be involved) improves care compared with observation, after a breast cancer PET scan of the armpit area. It may help people with certain early breast cancers avoid unnecessary procedures if the lymph nodes look negative on scans.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05241119Recruiting
Lymph node mapping to guide surgery after chemotherapy
This study tests using a special carbon-based tracing method to help doctors check which lymph nodes to treat during surgery after you finish chemotherapy. It may improve how accurately the surgical plan targets cancer in the armpit (axillary) lymph nodes.
