Pembrolizumab plus chemo before surgery for esophageal cancer
This trial tests whether giving pembrolizumab (an immune therapy) plus chemotherapy before surgery can improve outcomes for people with locally advanced, operable esophageal squamous cell carcinoma. It may help shrink the tumor and improve the chance of successful surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05284552RecruitingPhase 2
Tinzaparin blood-thinner and biomarkers after ovarian cancer surgery
This Phase 2 study tests whether the blood thinner tinzaparin used after neoadjuvant treatment can change blood markers (“biomarkers”) in people with certain stages of ovarian cancer. It aims to understand if tinzaparin affects the body’s cancer-related signals, which could help future treatment decisions.
Eksjö, EksjöAges 18 years+ - NCT05360290Recruiting
Study checks cancer cells in breast tissue after surgery
This trial looks for circulating tumor cells—cancer cells that may travel in the blood—after standard breast cancer treatment, including chemotherapy before surgery and surgery itself. It may help doctors understand who might be at higher risk and tailor follow-up care.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05420454RecruitingPhase 4
Neoadjuvant treatment for breast cancer before surgery
This trial tests a treatment given before breast surgery to shrink breast cancer and improve outcomes based on your tumor type. Your eligibility depends on tumor size/stage, hormone and HER2 markers, and overall health checks.
Hangzhou, ZhejiangAges 18 years+ - NCT05446467RecruitingPhase 2
Pembrolizumab before surgery for advanced head and neck cancer
This trial studies whether pembrolizumab, given before surgery, can improve outcomes for certain people with stage III–IVA head and neck squamous cell cancer. It’s typically added alongside low-dose PFAS as part of treatment leading up to standard surgery and afterward medicines/radiation.
Qingdao, ShandongAges 18–85 - NCT05475678RecruitingPhase 2
Camrelizumab plus chemo before surgery for triple-negative breast cancer
This Phase 2 trial tests adding camrelizumab (an immune therapy) to standard chemotherapy before surgery for people with triple-negative breast cancer that has not spread. It aims to improve how much the tumor shrinks before and around the time of surgery.
Zhengzhou, HenanAges 18–70 - NCT05571644RecruitingPhase 2
Study compares two pre-surgery treatments for locally advanced rectal cancer
This Phase 2 trial tests whether a newer combination chemotherapy plus an immunotherapy medicine (cadonilimab/AK104) works better than standard chemotherapy before surgery for locally advanced colorectal cancer. The goal is to shrink the tumor and improve how well treatment works after surgery.
Guangzhou, GuangdongAges 18–70 - NCT05576480RecruitingPhase 2
Immunotherapy plus chemotherapy before surgery for rectal cancer without mismatch repair
This Phase 2 study tests penpulimab (an immunotherapy medicine) given with CAPEOX chemotherapy before surgery for rectal cancer that is “MSS” (not the mismatch-repair type). It aims to shrink the tumor and improve outcomes by treating before the operation.
