Cellular Immunotherapy for Relapsed or Refractory Lymphoma Data Collection

This study aims to collect efficacy and safety data from adult patients with r/r NHL who received cellular immunotherapy between January 2017 and December 2040. Study investigators will determine the most appropriate diagnostic and treatment plans for patients based on clinical practice, without any intervention due to the existence of this study. No grouping will be conducted, and subgroup analyses will be performed based on the collected data. Data collection process: Clinical data will be collected from patients before cellular immunotherapy, before immune cell infusion, on the day of infusion, and at the last visit or follow-up within 24 months post-infusion. This includes collecting efficacy data, adverse events related to cellular immunotherapy, and survival data. Additionally, any new tumors, pathological findings, and other relevant laboratory or auxiliary examination data will be collected.
