  1. Model: Indicates a specific patient and patient-derived xenograft model
  2. Pathology: Judged by licensed pathologist (SY); %, percentage of the diseased cells judged by pathology; AC adenocarcinoma, SCC squamous cell carcinoma
  3. Regimen: Drug combinations used to test efficacy in specific PDX model and MiniPDX
  4. Chemotherapeutic or targeted drug: Single or combination of drugs used in PDX assay and in MiniPDX
  5. TGI: Tumor growth inhibition or TCGI: tumor cell growth inhibition. N = 6, results are mean ± SEM. Mean TGI or TCGI ≥ 45% is defined as positive therapeutic response (+)
