title: [Thyroid cancer during pregnancy].
abstract: OBJECTIVE
  To study the diagnosis and treatment of thyroid cancer during pregnancy.
  
  
  METHODS
  12 pregnant patients with thyroid cancer were retrospectively analysed.
  
  
  RESULTS
  Diagnosis was dependent on the clinical manifestation, the examination of B-ultrasonic and the fine-needle aspiration biopsy of thyroid, 4 patients who asked for ending pregnancy were operated on after abortion, 6 patients with early and middle pregnancy were operated on during pregnancy, and 2 patients with late pregnancy were operated on after delivery. No patients showed recurrence of cancer, and their children were healthy, and the shape and function of the children's thyroid were normal.
  
  
  CONCLUSIONS
  Pregnant patients with thyroid cancer during early and middle pregnancy should be operated on in time, and late pregnant patients should be operated on after delivery. All patients should take levothyroxine.
