Is Routine Dissection of Central Lymph Node Necessary for Papillary Thyroid Carcinoma, T1-2 N0?

informed consent taken, study was a prospective cohort study, with controlled group a retrospectively. patients ablated by total thyroidectomy only who failed to achieve ablation with the first dose of iodine 131I may be dynamically risk stratified as high-risk category and managed aggressively. N0 patients will benefit and ablated by total thyroidectomy and prophylactic central neck dissection, PCND decreases the residual, increase the RFS and patients without residual do not need adjuvant RAI therapy except in high risk group. Histological grading, size of the primary tumour, the extension of PTC, the extent of surgery were found to be a strong predicting factor for recurrence-free survival Locoregional recurrence cases always found more in male patients aged more than 45 years old. Size of the primary tumour and the extent of surgery was a significant factor for RFS,
