Lack of Influence of Pregnancy on the Prognosis of Survivors of Thyroid Cancer

Abstract

<br/><b>Objective</b>: The aim of this study is to investigate the influence of pregnancy on prognosis of thyroid cancer.<br/><b>Methods</b>: A total of 72 patients aged between 15-45 years who underwent total or subtotal thyroidectomy andsubsequently radioablation were followed up under suppression. Individuals who had term pregnancies afterdiagnosis of cancer (group 1, n: 36) and who were non-pregnant (group 2, n:36) were included in the study.Both groups were compared in terms of scintigraphic relapse and metastasis, ultrasonographic relapse, stagechange of lympadenopathy at the beginning and at the end of the study. <br/><b>Results</b>: Relapse was detected in 4 outof 36 pregnant patients (11.1%) and in 5 out of 36 non-pregnant patients (13.9%) with no significant differencebetween groups (p=1.00). Pathologic lymphadenopathy was detected in 2 out of 36 pregnant patients (5.6%) andin 2 out of 36 non-pregnant patients (5.6%) (p=1.00), and metastasis in 3 (8.3%) and in 1 (2.8%), respectively(p=0.61). While stage change was detected in only one pregnant patient (2.8%), and none of the non-pregnantagain there was no significant difference (p=1.00). <br/><b>Conclusions</b>: We conclude that pregnancy does not have aninfluence on prognosis of thyroid cancer.
