| Abstract | The purpose of this study was to describe the ultrasonography (US) image features and preoperative thyroid-stimulating hormone (TSH) level in patients with thyroid nodules read as or suspicious for papillary thyroid microcarcinoma (PTMC) on US-guided fine-needle aspiration biopsy (US-FNAB) and to identify the risk factors for central lymph node metastasis (CLNM) that can guide surgical strategies for patients diagnosed with PTMC on pathology. In this retrospective cross-sectional study, a total of 163 patients diagnosed cytologically and histopathologically were included. Cytological diagnosis for each patient preoperatively was based on the Bethesda classification for the nodule: 44 (27.0 %) were suspicious for papillary carcinoma (Bethesda V) and 119 (73.0 %) were positive for papillary carcinoma (Bethesda VI). PTMC was confirmed in 162 patients on pathology. In the multivariate analysis, the US suspicious images including nodal metastases, microcalcification, and irregular margins, tumor size larger than 7 mm on US, and serum TSH level equal to or greater than 2.5 mIU/L were independent predictors for CLNM in 162 patients diagnosed with PTMC. Prophylactic central lymph node dissection (CLND) may be considered in PTMC patients presenting with risk factors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
