Nutritional Status of Patients After Hematopoietic Stem Cell Transplantation

This study is looking at the nutritional status of patients who have undergone a hematopoietic stem cell transplant (HSCT), a procedure commonly used to treat blood cancers and other serious blood diseases. The transplant process and the treatments leading up to it can significantly affect a patient's ability to eat and absorb nutrients, putting them at risk for malnutrition. Researchers at the First Affiliated Hospital of Soochow University are collecting data to better understand how nutrition changes after transplantation and how those changes may affect recovery. This is an observational study — participants will not receive any special treatment, but will be monitored over time. You may be eligible if: - You are undergoing hematopoietic stem cell transplantation at the First Affiliated Hospital of Soochow University - You have a life expectancy of more than 3 months - You are between 15 and 80 years old You may NOT be eligible if: - You are not willing to participate - You are under 15 or over 80 years old Talk to your doctor to see if this trial is right for you.
