This study looks at how well nasopharyngeal cancer (NPC) responds to the first round of chemotherapy before other treatments. It aims to see if the amount of tumor shrinkage can help predict outcomes and guide future care for people with advanced NPC.
Nanchang, JiangxiAges 18 years+ - NCT04293796Recruiting
Skipping breast surgery after complete response
This trial looks at whether some people with breast cancer can safely avoid breast surgery after they respond completely to treatment before surgery. If you have no remaining cancer in the tissue and lymph node tests, this study checks whether the “watch-and-wait” approach is feasible and safe.
Saint PetersburgAges 18–70 - NCT05020860RecruitingPhase 2
Study how early breast cancer responds on imaging and under a microscope
This Phase 2 study looks at how well early breast cancer shrinks with treatment and how that matches with what doctors find after surgery under the microscope. The goal is to learn better ways to predict and assess treatment success.
Houston, TexasAges 18 years+ - NCT07088354Recruiting
AI model predicts treatment response in esophageal cancer
This trial tests whether an artificial intelligence (AI) model can accurately predict if esophageal cancer will completely disappear after chemotherapy combined with immunotherapy before surgery. If successful, it could help doctors decide the best treatment plan for patients.
Wuhan, HubeiAges 18 years+ - NCT06299202Recruiting
Predicting breast cancer treatment response with special mammogram
This study uses a special type of mammogram with contrast dye to see if it can predict how well breast cancer responds to chemotherapy before surgery. It's for people with HER2-positive or triple-negative breast cancer.
LyonAges 35 years+ - NCT07289282Recruiting
Study of blood markers and chemotherapy response in breast cancer
This trial is studying tiny molecules in your blood (called microRNAs) to see if they can predict how well breast cancer responds to chemotherapy given before surgery. If you are starting neoadjuvant chemotherapy, this study may help personalize your treatment.
IstanbulAges 18 years+ - NCT07671885RecruitingPhase 3

This trial tests if giving hormone-blocking pills before surgery can help guide which treatments you need after surgery. It is for premenopausal women with early-stage, hormone-sensitive breast cancer.
AkitaAges 18 years+ - NCT06364371Recruiting
Predicting rectal cancer treatment response using multi-omics
This trial is testing a new way to predict how well your rectal cancer will respond to treatments given before surgery. It uses advanced tests (like looking at genes and other markers) to tailor your care.
Guangzhou, GuangdongAges 18–80 - NCT05777824RecruitingPhase 2
Testing treatment after head and neck cancer response to chemo-immunotherapy
This Phase 2 study looks at what treatment is best after you first receive chemotherapy plus immunotherapy, then have surgery for head and neck squamous cell cancer. It tries to use how your tumor responds (shown in lab tissue after treatment) to guide the next steps, which may improve outcomes.
Beijin, Beijing MunicipalityAges 18–75 - NCT05125055RecruitingPhase 2/Phase 3
Test new throat cancer treatment before surgery
This trial tests giving anti–PD-1 immunotherapy plus a drug called TP before surgery for oral squamous cell carcinoma (mouth/throat cancer). The goal is to see whether this pre-surgery treatment improves how much the tumor responds under the microscope.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05512481RecruitingPhase 2
Study combination treatment before surgery for high-risk acral melanoma
This Phase 2 trial tests three medicines given before surgery for people with high-risk acral melanoma (a skin cancer type). It aims to shrink or control the cancer earlier and see how well the treatment works and is tolerated.
Beijing, Beijing MunicipalityAges 18–75 - NCT07251582RecruitingPhase 3
Comparing infusion timing for lung cancer immunotherapy before surgery
This trial tests whether the timing of immunotherapy infusion before surgery improves how well the tumor responds in people with stage II to III non-small cell lung cancer. It combines immunotherapy with standard chemotherapy to shrink the tumor before it is removed.
Changsha, HunanAges 18–75 - NCT06754904Recruiting
Skipping lymph node removal for melanoma with good treatment response
This trial tests whether patients with stage 3 melanoma that shrinks significantly after initial immunotherapy can safely avoid having all their lymph nodes surgically removed. Instead, only the main affected node is removed for testing.
Rotterdam, South HollandAges 16 years+ - NCT05981326Recruiting
Computer model to predict chemo response in early breast cancer
This study looks at how well a computer model can predict if breast cancer will completely respond to chemotherapy before surgery. It is for people with early-stage breast cancer who are about to start neoadjuvant chemotherapy.
AngersAges 18 years+ - NCT05167487Recruiting
Study of treatment effects after chemotherapy and surgery for lung cancer
This trial looks at how lung tumors respond after chemotherapy given before surgery in people with stage IIIA non-small cell lung cancer (NSCLC). It may help doctors understand which past treatments lead to better results, since it uses medical records from approved clinical cases.
A Coruña, A CoruñaAges 18 years+ - NCT04741997RecruitingEarly Phase 1
Adjuvant melanoma treatment guided by response to targeted drugs
This early-phase study looks at whether people with melanoma can get the “right” follow-up (extra) treatment based on how well their cancer responds after starting targeted drugs before surgery. The goal is to improve outcomes while better matching treatment to each person’s tumor response.
Tampa, FloridaAges 18 years+ - NCT07593976RecruitingPhase 2
New PET scan to predict breast cancer treatment response
This study tests a new type of PET scan (a specialized imaging test) to see if it can predict whether chemotherapy will work for HER2-positive breast cancer before surgery. The scan uses a radioactive tracer designed to highlight HER2-positive cancer cells, helping doctors personalize your treatment plan.
RouenAges 18 years+ - NCT05939830Recruiting
Skipping axillary lymph node surgery after treatment response
This study looks at whether some breast cancer patients can safely skip a surgery that removes lymph nodes in the armpit after their initial (pre-surgery) treatment shows the armpit is likely clear. It may reduce surgical side effects if the armpit truly responds well.
NanjingAges 18–70 - NCT05416164Recruiting
Testes less radiation after a complete response to medicines
This study checks whether some people with breast cancer who have no remaining cancer after medicine (neoadjuvant systemic therapy) can safely receive less radiation. It may help reduce side effects while still keeping cancer controlled.
Amsterdam, North HollandAges 18 years+ - NCT07066189Recruiting
Diet and exercise during chemo for triple negative breast cancer
This study looks at whether a program of healthy eating and exercise, started during chemotherapy, can help shrink your tumor more effectively. You will be randomly assigned to either follow the diet and exercise plan or stick with your usual care.
New Haven, ConnecticutAges 18 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.
