Is Routine Dissection of Central Lymph Node Necessary for Papillary Thyroid Carcinoma, T1-2 N0?
Is Routine Dissection of Central Lymph Node Necessary for Papillary Thyroid Carcinoma, T1-2 N0?
study assigned into three groups, Group I was the control group operated by total
 thyroidectomy and retrospectively followed, where the other two groups Operated by Total
 thyroidectomy and central neck dissection. Recurrence Free Survival (RFS) was the main issue
 of the study and calculated as the time from date of surgery to date of relapse or the most
 recent follow-up contact that patient was known as relapse-free, Study exclusively studied
 the outcome and advantage of central neck dissection
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,
Inclusion Criteria:

 Exclusion Criteria:
