Prognostic Factors for Excellent Response to Initial Therapy in Patients With Papillary Thyroid Cancer From a...

Area of Science:

• Endocrinology
• Oncology
• Surgical Oncology

Background:

• Prognostic factors for excellent response (ER) to initial therapy in papillary thyroid cancer (PTC) remain undetermined.
• Understanding these factors is vital for optimizing patient management and treatment strategies.

Purpose of the Study:

• To investigate the response to initial therapy in PTC patients.
• To identify independent prognostic factors associated with ER in PTC.

Main Methods:

• A prospective multicenter study involving 506 PTC patients in China.
• Patients underwent total or near-total thyroidectomy, lymph node dissection, and radioiodine therapy.
• Univariate and multivariable logistic regression analyses were used to determine prognostic factors.

Main Results:

• 27.5% of patients achieved ER after initial therapy.
• Extrathyroidal extension, number of metastatic lymph nodes, and preablative-stimulated thyroglobulin (Ps-Tg) were independent risk factors for ER in the overall population.
• Subgroup analyses revealed specific risk factors for pathological N1a and N1b patients.

Conclusions:

• Extrathyroidal extension, number of metastatic lymph nodes, and Ps-Tg are significant prognostic factors for ER in PTC patients.
• These factors can aid in predicting treatment outcomes and tailoring therapeutic approaches.
• Identifying patients at higher risk for poor response is essential for personalized PTC management.
