Aim: To evaluate whether differences exist in terms of patient, radiological, tumour characteristics and surgical complications between malignant and benign thyroidectomy.
Materials and methods: 184 correlatives cases of thyroidectomy during the period from October 2011 to October 2013 are analysed. Patient, ultrasound, tumour and complication characteristics are compared. Categorical data are reported as percentages. Characteristics between the two groups are compared using a Students t-test for continuous variables and a Fishers exact test or a χ2 test for categorical variables.
Results: A female: male ratio of 5:1 (157 women: 28 men) is found with eight malignant cases (28.6%) in men and 35 (22.3%) in women. Malignancy is associated with family cancer history (RR: 0.3 (0.1830.143)), and larger tumour size with benignity. Benignity nodules are 1, 21 cm larger than malignity nodules (P: 0.00 (0.4741.567). No statistically significant differences in terms of age, mean operative time, mean postoperative hospital stay and surgical complications are found.
Conclusions: The nodule size is not an accurate predictor of thyroid cancer. Malignant thyroidectomy is not associated with more surgical complications or postoperative hospital stay.
