ShanghaiAges 18–80 - NCT06601309RecruitingPhase 2
Study of treatments before surgery for esophageal cancer
This trial is testing different treatment combinations before surgery for people with locally advanced esophageal squamous cell carcinoma. The goal is to find which approach works best based on specific biomarkers like PD-L1 levels.
Fuzhou, FujianAges 18–75 - NCT06602011Recruiting
Triple therapy for advanced liver cancer with bile duct invasion
This study tests a combination of three treatments—TACE (a procedure that blocks blood flow to the tumor), lenvatinib (a targeted therapy pill), and tislelizumab (an immunotherapy)—for people with liver cancer that has spread into the bile ducts and can't be removed by surgery. The goal is to see if this triple therapy helps shrink or control the cancer.
Fuzhou, FujianAges 18–75 - NCT06602037Recruiting
ImmunoPET imaging for pancreatic cancer
This trial tests a new imaging method called ImmunoPET to see if it can help detect pancreatic cancer more clearly. If you have or might have pancreatic cancer, this study could help doctors understand your condition better.
