Abstract

Abtract:


The purpose of the study: to describe the clinical and subclinical symptoms and evaluate the response after recurrent lympho node dissection of differentiated thyroid cancer patients after 131I treatment. Subjects: 50 differentiated thyroid cancer patients after 131I treatment, recurrence for the first time. Methods: Retrospective and prospective description, data collection through patient records. Results: the mean age of the study patients was: 43.5 ± 12.6, the most common age is <55 years old with the rate of 80%, the female/male ratio=3.5/1. The group of patients with Tg < 1 ng/ml accounted for the majority with 33/50 patients (66%). The median Tg before and after surgery was 2.02 ng/ml and 0.35 ng/ml, respectively. After surgery, response achieved in 98% of patients, mainly complete response and incomplete response in biochemical, accounted for 40%, 36%. Lymph node dissection reduced Tg in 78% of patients. Reccurent lympho nodes mainly observed in group IV, group III and group VI. The recurrence of lymph nodes was mainly in the central and cervical regions on the same side of the primary tumor. Conclusion: Surgery is the preferred first-line treatment for the reccurent lymph node thyroid cancer patients. It changes response assessment, improve prognosis for reccurent patients after 131I treatment.


Keywords: Differentiated thyroid cancer, response after recurrent lympho node dessection, Tg
