Real-World Clinical Study for Malignant Tumor-Induced Cachexia

This study is a non-interventional, multicenter observational study, aiming to assess the clinical characteristics and treatment outcomes of malignant tumor cachexia. The study is mainly divided into two cohorts: Retrospective Cohort: This cohort focuses on patients who have already been diagnosed with cachexia before the initiation of this study. It involves the retrospective collection and analysis of clinical data. Prospective Cohort: This cohort includes patients who are diagnosed with cachexia after the start of this study. Data will be prospectively collected and analyzed during their subsequent diagnosis and treatment process.
