Safety and Efficacy of Umbilical Cord Blood Therapy for Cancer Therapy-Induced Thrombocytopenia (CTIT)

This study is a prospective, single-center, open-label, single-arm clinical trial to assess the safety and efficacy of umbilical cord blood in cancer treatment-induced thrombocytopenia (CTIT) patients. It plans to recruit subjects aged 12 to 65 years old with CTIT. The study involves intravenous infusion of umbilical cord blood, with platelet transfusion as supportive therapy if necessary. The trial consists of three phases: screening (baseline assessments and enrollment), treatment (umbilical cord blood infusion), and follow-up (blood routine tests at Days 3, 7, 14, and 28 post-treatment to record platelet counts, first response time, maximum and minimum values, and calculate efficacy rates while observing changes in thrombocytopenia grading). A total of 25 subjects will be enrolled, and they will undergo evaluation for safety and efficacy based on treatment-related adverse events, GVHD incidence, and hematological improvements.
