Summary

Poorly differentiated thyroid carcinoma (PDTC) is an aggressive cancer. Surgical treatment followed by radioiodine therapy offers an 85% survival rate, but close monitoring is crucial due to relapse risk.

Area of Science:

  • Endocrinology
  • Oncology
  • Pathology

Background:

  • Poorly differentiated thyroid carcinoma (PDTC) is a rare but aggressive thyroid cancer subtype.
  • It is the leading cause of mortality among non-anaplastic follicular cell-derived thyroid cancers.
  • Limited data exist on its clinical behavior and treatment consensus due to its novelty.

Purpose of the Study:

  • To describe the clinical experience with PDTC at a tertiary medical center in Morocco.
  • To analyze clinico-pathological characteristics, treatment strategies, and outcomes over a 7-year period.

Main Methods:

  • Retrospective study of patients treated for thyroid carcinoma.
  • Data collected included patient demographics, tumor characteristics, surgical procedures, radioiodine therapy (RIT), and follow-up outcomes.
  • Seven patients diagnosed with PDTC were included.

Main Results:

  • The study included seven patients (6 female, 1 male) with a mean age of 60.
  • Most patients had advanced disease (70% pT3) with vascular invasion (85%) and insular carcinoma subtype (85%).
  • All patients underwent total thyroidectomy and RIT, with 57% also receiving cervical lymph node dissection. Complete remission was achieved in 57%, with a current survival rate of 85%.

Conclusions:

  • PDTC is an aggressive thyroid cancer requiring prompt management.
  • Surgical resection followed by RIT for radioiodant tumors is the primary treatment approach.
  • Multimodality therapy and vigilant follow-up are essential due to the high risk of recurrence.
