A comparison of haemogram parameters of patients with thyroid papillary cancer and nodular goiter in Van, Turkey

Objective: To compare the haemogram parameters of patients with thyroid papillary cancer and nodular goiter. Methods: The retrospective comparative study was conducted at Van Training and Research Regional Hospital, Van, Turkey, and comprised data of patients who underwent thyroidectomy from 2011 to 2015. The data was compared between patients with papillary thyroid cancer (group 1) and those with nodular hyperplasia (group 2) in terms of age, gender and thyroid stimulating hormone level as well as haemogram parameters, neutrophil-lymphocyte ratio and platelet-lymphocyte ratio. SPSS 20 was used for statistical analysis. Results: Of the 90 patients, 53(59%) were in group 1 with papillary thyroid cancer and 37(%) in group 2 with nodular hyperplasia. Platelet-lymphocyte ratio was significantly higher in group 1 (p=0.015). Mean platelet volume was significantly higher in group 1 patients with a diameter of 1cm or more (p<0.05). Within group 1, lymphocyte count was significantly high in patients with invasion (p<0.05). In correlation analysis, group 1 patients with a tumour diameter of 1cm or more showed a significant correlation in mean platelet volume, tumour multicentricity, lymphocyte count, vascular invasion, thyroglobulin, platelet distribution width, platelet number and tumour multicentricity (p<0.05). Conclusion: Only platelet-lymphocyte ratio could assist in distinguishing benign goiter from thyroid cancer. Also, mean platelet volume, lymphocyte count, and platelet distribution width appeared to be effective prognostic markers for papillary thyroid cancer.
