This study found that thyroid biopsies are disproportionately high compared to thyroid cancer deaths, suggesting potential overconsumption of healthcare resources for thyroid nodule investigation.

Area of Science:

  • Radiology
  • Oncology
  • Health Resource Management

Background:

  • Image-guided biopsies are crucial for cancer diagnosis.
  • Assessing resource allocation in radiology departments is essential for efficient healthcare delivery.
  • Thyroid nodule investigation trends warrant examination regarding resource utilization.

Purpose of the Study:

  • To evaluate the adequacy of departmental resource allocation for ultrasound-guided thyroid biopsies.
  • To compare resource allocation for thyroid biopsies against other common cancer types.

Main Methods:

  • Collected data on breast, prostate, and thyroid biopsies performed in 2009.
  • Obtained predicted cancer mortality data for Canada from the Canadian Cancer Society.
  • Calculated biopsy-to-cancer mortality ratios for each organ.

"Sun's Seven-Step Technique" for Endoscopic En-Bloc Resection of Thyroid Cancer via the Chest-Breast Approach

Published on: November 28, 2025

Main Results:

  • Over 2,400 breast, 910 prostate, and 610 thyroid biopsies were performed.
  • The biopsy ratio per cancer burden was 7x higher for thyroid than breast cancer.
  • The biopsy ratio per cancer burden was 15x higher for thyroid than prostate cancer.

Conclusions:

  • The high ratio of thyroid biopsies to cancer mortality suggests potential overuse of health resources.
  • Current trends in investigating thyroid nodules may indicate overconsumption.
  • Further evaluation of resource allocation for thyroid nodule workups is recommended.
