OBJECTIVE: The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have recently been introduced as prognostic markers of thyroid cancer and strong inflammatory markers. The study was performed to investigate the association of the PLR and NLR with thyroid inflammation and papillary cancer.
METHODS: Patients with thyroiditis and patients with papillary carcinomas were compared with sex-, age-, and body mass index-matched healthy controls. The NLR and PLR were calculated and compared among the three groups.
RESULTS: The NLR was significantly higher in patients with thyroiditis and non-significantly higher in patients with papillary cancer than in healthy controls. The PLR was significantly higher in both patients with thyroiditis and papillary cancer than in healthy controls. Like the NLR, the PLR was not different between patients with thyroiditis and papillary cancer. The NLR was significantly and positively associated with the PLR and white blood cell count.
CONCLUSION: The PLR and NLR showed similar results in both thyroid inflammation and cancer. It seems difficult to obtain clear results in separating cancer from inflammatory events using these parameters. We suggest using them as supportive parameters of thyroid papillary cancer or inflammation.
