ABSTRACT
Objectives: To evaluate the surgical approaches and prognosis of thyroid carcinomas invading the adjacent structures
Methods: The medical records of 197 patients with a pathology diagnosis of thyroid cancer were retrospectively reviewed
Results: Seventeen patients [9%] with thyroid carcinoma invading surrounding structures were included. Patients were initially divided into two groups on the basis of tumor histology: papillary [Group A] and nonpapillary [Group B]. Then patients were divided into three groups Group 1: patients who underwent total thyroidectomy Group 2: patients who underwent total thyroidectomy with shaving resection Group 3: patients who underwent total thyroidectomy with extensive surgery. All patients who didn't survive were more than 45 years old. The survival rate was statistically better in group A compared to group B [92% versus 20%]. The survival rate decreased from Group 1 through Group 3, without reaching statistical significance
Conclusions: Age and histologic type are important in determining the prognosis of locally invading thyroid cancer
