BackgroundThere is much debate in the literature over the extent of surgery for patients with intermediate risk papillary thyroid cancer. We herein report our results in a local tertiary hospital.MethodWe identify from our database patients with papillary thyroid cancer who underwent surgery in our hospital and were stratified to be of intermediate risk from the GAMES stratification system. Patients' demographic data, surgical and pathological details were recorded. Primary end points were disease specific survival (DSS) and recurrence free survival (RFS).ResultsFrom January 1993 to December 2016, 231 patients with papillary thyroid cancer underwent surgery of which 137 (59%) were of intermediate risk. 45 (33%) patients had hemithyroidectomy and 92 (67%) patients had total thyroidectomy. In the total thyroidectomy group, patients had a higher tumor (T) (p value = 0.009) and nodal (N) staging (p value = 0.001). They were also predicted to have a higher risk of recurrence according to the American Thyroid Association (ATA) classification (p value = 0.005). The 5 year DSS in both groups were 100%. The 5 year RFS in the total thyroidectomy and hemithyroidectomy groups were 92% and 100% respectively and were significantly different by the log rank test (p value = 0.02). The median follow up time was 54 months (range 4-276 months).ConclusionThe 5 year survival in intermediate risk papillary thyroid cancer is favorable. Hemithyroidectomy is an acceptable choice of operation in intermediate risk patients with a better risk profile.Copyright © 2019 Elsevier Inc. All rights reserved.
