Objective: To compare the diagnostic performance of American College of Radiology-Thyroid Image Reporting and Data Systems (ACR-TIRADS) and the American Thyroid Association (ATA) guidelines on screening for thyroid malignancy. Methodology: A cross-sectional criterion-referenced study involving Filipino patients with thyroid nodules, 18-80 years old, who underwent ultrasound guided fine needle aspiration biopsy at the Thyroid Clinic of The Medical City from July to December 2019. The ACR-TIRADS and the ATA guidelines were compared for 197 nodules. Standard diagnostic parameters were calculated, namely sensitivity, specificity, PPV, NPV, positive and negative likelihood ratios and overall accuracies. Results: The risks of malignancy were 15% and 22% for TIRADS 4 and 5 respectively. For ATA guidelines, it’s 2%, 20%, and 15% for nodules with low, intermediate, and high suspicion respectively. The sensitivity, specificity, PPV, NPV, and accuracy of the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TIRADS) in relation to Fine Needle Aspiration Cytology (FNAC) is 100%, 52.2%, 16.5%, 100%, and 56.4% respectively. For the American Thyroid Association (ATA) guidelines it is 88.2%, 57.8%, 16.5%, 98.1%, and 60.4% respectively. Conclusion The ACR TIRADS classifications appears to be more sensitive than the ATA classification. The ATA guidelines prove to be a more specific test. Each tool has its unique advantages and disadvantages. Therefore, clinicians must use these tools with utmost vigilance to avoid over or under diagnosis and to avoid unnecessary thyroid nodule biopsies.

Objective: To compare selected clinicodemographic factors of patients with thyroid nodules who underwent thyroid surgeries with their tissue biopsy results and determine any association between clinicodemographic factors and tissue biopsy results. Methods: Design: Retrospective review of records. Setting: Tertiary Government Training Hospital. Participants: 251 patients with thyroid nodules. Results: Of 251 patients with thyroid nodules, the majority (218; 86.9%) were females while 33 (13.1%) were males. The average age in years was 41.5±13.3 The same population also had malignant outcomes at 79.3%. Most of the patients did not have family history of thyroid malignancy (54%) and had no palpable cervical lymph nodes at presentation (75.9%). Furthermore, there was no distant metastasis at presentation for both lungs (97.7%) and bones (98.9%). There were no significant differences in tissue biopsy results when correlated with age (df=249; t=-.144; p = .886), duration of goiter (df=249; t=-.829; p = .408), and distant metastasis at presentation for lungs (Z=-5.977; p = .052) and bones (Z=-.457; p = .648). Significant differences were only evident for clinicodemographic factors such as sex (Z=-2.570; p = .010), family history (Z=-2.239; p = .020), palpable cervical lymph nodes at presentation (Z=-5.977; p = .000), and the following comorbidities: pulmonary tuberculosis (Z=-2.388; p = .017) and bronchial asthma (Z=-2.148; p = .032) and smoking history (Z=-3.455; p=.001). Furthermore, having no palpable cervical lymph nodes at presentation were associated with malignant tissue biopsy results (B=3.616; p=.001). Patients without palpable cervical lymph nodes at presentation were 37.204 times [OR=37.204] more likely to have benign biopsy results [95% CI: 4.705 – 294.168]. Conclusion There are greater odds of having benign biopsy results for patients without palpable cervical lymph nodes at presentation.

8.An executive summary of the Philippine Interim Clinical Practice Guidelines for the Diagnosis and Management of Well Differentiated Thyroid Cancer 2021

Acta Medica Philippina 2024;58(8):5-30

Objectives: Thyroid cancer is the most common endocrine cancer in the Philippines affecting primarily women in the reproductive age group. Considering the burden of thyroid cancer in the country, the Department of Health (DOH) called for the development of a national clinical practice guideline that would address patient needs, and aid physicians in clinical decision-making while considering therapeutic cost and availability in the local setting. The 2021 guidelines are aimed at providing optimal care to Filipino patients by assisting clinicians in the evaluation of thyroid nodules and management of well differentiated thyroid cancer. Methods: A steering committee convened to formulate clinical questions pertaining to the screening and evaluation of thyroid nodules, surgical and post operative management of thyroid cancer, and palliative care for unresectable disease. A technical working group reviewed existing clinical guidelines, retrieved through a systematic literature search, synthesized clinical evidence, and drafted recommendations based on the ADAPTE process of clinical practice guideline development. The consensus panel reviewed evidence summaries and voted on recommendations for the final statements of the clinical practice guidelines. Results: The guidelines consist of clinical questions and recommendations grouped into six key areas of management of well differentiated thyroid cancer: screening, diagnosis, surgical treatment, post operative management, surveillance, and palliative care. Conclusion The 2021 guidelines for well differentiated cancer could direct physicians in clinical decision making, and create better outcomes for Filipino patients afflicted with the disease. However, patient management should still be governed by sound clinical judgement and open physician-patient communication.

PURPOSE: To review the retrospective imaging findings of thyroid cancer initially assessed as no suspicious malignancy. MATERIALS AND METHODS: Of 338 nodules confirmed to be thyroid cancer, this study included 38 patients with 39 nodules assessed as no suspicious malignancy on initial sonography. (mean age: 39 years, 36 females and 2 males). We evaluated sonographic findings by shape, margin, echogenecity, calcification, cystic degeneration and peripheral hypoechoic rim retrospecively. We analyzed whether sonographic findings were different according to the size (standard: 1 cm). RESULTS: The most frequent sonographic findings were ovoid to round shape 90%, well-defined smooth margin 64%, hypoechogenecity 54%, no calcification 92%, no cystic degeneration 77% and peripheral hypoechoic rim 56%. Suspicious malignancy findings were taller than wide shape 10%, well-defined spiculated margin 36%, markedly hypoechogenecity 10% and microcalcifications 8%. Isoechogenecity, cystic degenetaion and peripheral hypoechoic rim were common in 1 cm more than nodules. Well-defined spiculated margin was common in 1 cm less than nodules. In retrospective, 56% showed no suspicious malignancy finding. CONCLUSION: Although nodules assessed as no suspicious malignancy on initial US had many retrospectively suspicious malignancy findings, still many nodules showed no suspicious malignancy finding. Suspicious findings were ignored due to equivocal finding in small size, isoechogenecity, cystic degeneration or peripheral hypoechioic rim. We need careful observation.
