Treating advanced esophageal cancer with dalpiciclib and pyrotinib
This trial tests a combination of two targeted drugs (dalpiciclib and pyrotinib) for people with advanced esophageal squamous cell carcinoma whose cancer has gotten worse during or after first chemotherapy. The goal is to see if this drug pair can help shrink tumors or slow the disease.

Predictors of complications in laparoscopic surgery
This study looks at factors that may predict complications after laparoscopic surgery (minimally invasive surgery with a camera) when the patient is tilted head-down (Trendelenburg position). It focuses on surgeries lasting longer than 2 hours.
Jerusalem, YerushalaimAges 18 years+ - NCT06685887RecruitingPhase 2
Chemo, Immunotherapy, and Heated Belly Chemo for Stomach Cancer Spread
This trial tests combining standard chemotherapy and immunotherapy (tirelizumab) with heated chemotherapy given directly into the belly. It aims to treat stomach cancer that has spread to the abdominal lining, and may help shrink or control the cancer.
Wuhan, HubeiAges 18–75 - NCT06686576RecruitingPhase 3
Study of QL1706 before surgery for MSI-H colon cancer
This trial tests a new immunotherapy medicine (QL1706) given before surgery to treat colon cancer that hasn't spread yet. It's designed for patients whose tumors have a specific gene feature (MSI-H/dMMR) and who haven't had any prior treatment for this cancer.
