[Risk groups in differentiated thyroid carcinomas]

Area of Science:

• Endocrinology
• Oncology
• Surgical Pathology

Context:

• Well-differentiated thyroid carcinoma (WDTC) accounts for 80% of thyroid malignancies.
• Despite increasing incidence, survival rates for WDTC remain stable at over 95% at 20 years for 80% of cases.
• Accurate prognostic factor evaluation is crucial for stratifying patients into high- or low-risk groups.

Purpose:

• To review the incidence of malignant thyroid neoplasms using TNM, GAMES, and MACIS staging systems.
• To analyze the rate of post-surgical complications in thyroid cancer patients.
• To assess the distribution of risk groups in WDTC based on established staging systems.

Summary:

• Malignant neoplasms constitute 28.8% of thyroidectomies, with 88% being WDTC.
• Approximately 80% of WDTC patients fall into the low-risk category across all three staging systems.
• Low rates of permanent complications were observed: 1.2% for recurrent nerve palsy and 2.7% for hypocalcemia.

Impact:

• The study confirms that the majority of WDTC patients are low-risk with a favorable prognosis.
• Risk stratification aids in tailoring treatment strategies, preventing overtreatment in low-risk individuals.
• Personalized treatment approaches can minimize surgical complications and improve patient outcomes.
