Perioperative immunotherapy plus TACE-HAIC for liver cancer with portal vein tumor thrombus
This trial tests a combination of immunotherapy (sintilimab), a targeted anti-angiogenic drug (bevacizumab biosimilar), and liver-directed therapies (TACE-HAIC) before and after surgery for hepatocellular carcinoma that has spread to the portal vein. The goal is to see if this approach improves outcomes for patients with advanced but resectable liver cancer.

Seattle, WashingtonAges 18 years+ - NCT06032676Recruiting
Surgeons’ views on infant bowel disease decisions
This study interviews surgeons who treat infants with a serious bowel condition called necrotising enterocolitis (NEC). Researchers want to understand how surgeons make decisions and how babies do afterward.
Southampton, HampshireAges Up to 4 months - NCT06033976Recruiting
Registry for endoscopic removal of digestive tract growths
This study collects information on people who are having a procedure called endoscopic submucosal dissection to remove abnormal growths in the digestive tract. It helps doctors learn more about how well the procedure works and who benefits most.
BucharestAges 18–100 - NCT06034977RecruitingPhase 2
ADI-PEG 20 and Lenvatinib for liver cancer
This trial tests a combination of two drugs, ADI-PEG 20 and Lenvatinib, for people with advanced liver cancer that cannot be removed by surgery. It aims to see if this combination can help shrink or control the cancer.
TaoyuanAges 18 years+ - NCT06035250Recruiting
AI predicts stomach cancer response to chemo before surgery
This study tests whether an AI tool can predict how well stomach cancer responds to chemotherapy before surgery. It uses CT scans and biopsy images taken before treatment starts to see if the AI can help guide future care.
BeijingAges 18 years+ - NCT06036745RecruitingPhase 2
Palizumab and SOX chemo after gastric cancer surgery
This trial tests adding palizumab (an immunotherapy) to standard SOX chemotherapy after surgery for stage IIIB-IIIC gastric or GEJ cancer. It's for people whose tumors have certain markers (MSI-H, TMB-H, or high PD-L1) that may make immunotherapy more effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06037980RecruitingPhase 2/Phase 3
Chemotherapy before surgery for high-risk bile duct cancer
This trial tests whether receiving chemotherapy (cisplatin, gemcitabine, and nab-paclitaxel) before surgery can improve outcomes for people with high-risk bile duct or gallbladder cancer. It compares this approach to going straight to surgery.
AnconaAges 18–75 - NCT06037902Recruiting
CPAP during radiation for esophageal cancer
This study tests whether using a CPAP mask (which gently pushes air into your airways) during radiation therapy makes treatment safer and more effective for esophageal cancer. It is for adults who are planning radiation and can tolerate wearing the mask.
Ramat GanAges 18 years+ - NCT06037954Recruiting
Mental health support for older adults with cancer
This study offers mental health care for older adults (65+) with breast, colorectal, lung, or prostate cancer who are getting treatment or recently finished. It aims to help people who are also feeling depressed.
