Intelligent Diagnostic System for Papillary Thyroid Carcinoma

چکیده
Due to exponential growth and high diversity of DICOM images in healthcare industry, medical image mining has gained prominent attention because extraction of useful and effective patterns is one of the major problems in DICOM images. For instance, differentiating between the mimic, mix and complex patterns of thyroid papillary carcinoma (PTC) and other cancers in FNAC images is really challenging since it requires in-depth study of cells and tissues. In order to reduce the chances of misdiagnosis of thyroid cancer and to discernment the mimic lesions of papillary thyroid carcinoma (Small cell carcinoma may mimic insular carcinoma). This article proposes a framework, so called (IDSPTC) Intelligent Diagnostic System for papillary thyroid carcinoma, which offers a systematic way to classify papillary and non-papillary structures by using AI base techniques. In first phase, we prepared own dataset due to unavailability of training and testing datasets in literature. We applied our proposed algorithm “DICOM_Segs graph-Sag” to extract the useful movement and coordinate based patterns of nuclei and constructed decision model using ANN (artificial neural network) to identify the papillary structures by analysing nuclei coordinates; finally we performed test model and performance evaluation to measure the classification accuracy using confusion matrix, precision and recall measures and visualized the ROC curve for papillary and non-papillary classes. The measured accuracy of our proposed system is 90.32% with 10-k fold cross validation.

Thyroid Papillary Microcarcinoma: Etiology, Clinical Manifestations, Diagnosis, Follow-up, Histopathology and Prognosis
Background: Thyroid carcinoma is the most common malignancy of the endocrine system. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. Thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. As a result of diagnostic methods improvement, p...

The most usual form of the endocrine carcinoma is thyroid cancer (TC). In addition to papillary thyroid carcinoma (PTC), recent studies revealed incidence of RET/PTC rearrangement in other tumors, like Hürthle cell carcinoma (HCC) and even in non-carcinomatous disorders like Hashimoto's thyroiditis. Here, we present a case with concurrence of papillary thyroid carcinoma and Hürthle cell carcino...

The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinog...

Papillary thyroid carcinoma (PTC) is one of the most commonly diagnosed types of differentiated carcinoma of the thyroid. It is stated that lung is the most common site of metastasis followed by bone. The incidence of paranasal sinus (PNS) metastasis is fairly uncommon in case of thyroid carcinoma. To the best of our knowledge, no case of metastatic PTC to nasal cavity has been reported. In thi...
