  20. The magnitude of maximum fluorodeoxyglucose uptake in primary tumors and the serum TK1 level in patients with metastatic NSCLC were found to be independent prognostic predictors of overall survival. PMID: 23116493
  21. Increased serum level of thymidine kinase 1 correlates with metastatic site in patients with malignant melanoma. PMID: 23179401
