Relation between surgical oncologic quality indicators for papillary thyroid cancer.

Area of Science:

• Surgical Oncology
• Endocrine Surgery
• Quality Improvement in Medicine

Background:

• Thyroid surgical oncologic quality indicators (TSOQIs) require clearer understanding for effective surgical quality assurance.
• The interrelationships between key TSOQIs are not well-defined.

Purpose of the Study:

• To examine the relationship between postoperative serum thyroglobulin level, 24-hour radioactive iodine uptake (RAIU), and metastatic lymph node ratio (MLNR).
• To evaluate the clinical utility of these thyroid cancer quality indicators.

Main Methods:

• Retrospective review of 139 patients undergoing total thyroidectomy for papillary thyroid cancer (PTC).
• Analysis of correlations between serum thyroglobulin, RAIU, MLNR, and the MACIS prognostic score using Spearman correlation coefficient.

Main Results:

• Weak correlation found between serum thyroglobulin and RAIU (r=0.27, p=0.006).
• Moderate correlation observed between serum thyroglobulin and MLNR (r=0.40, p=0.002).
• Weak correlation noted between serum thyroglobulin and MACIS score (r=0.20, p=0.05).

Conclusions:

• Postoperative serum thyroglobulin level is a clinically useful quality metric for PTC surgery as it is universally measurable and correlates with other indicators.
• Surgeons may consider incorporating serum thyroglobulin level as a TSOQI in practice for evaluating thyroidectomy quality.
