Filter by:The oncologic benefit of lateral neck dissection (LND) during index operation for sporadic medullary thyroid carcinoma (MTC) basing on basal calcitonin (bCT) levels has been questioned due to the potential post-operative complications. This study aims to evaluate desmoplastic reaction (DSR), as predictor of nodal metastases, for definition of surgical strategy. Data from pathological report of MTC after operations between 1997 and 2022 were collected. The primary endpoint of the study was evaluating the risk factors for nodal metastases. The secondary endpoints analyzed the correlations between DSR and nodal metastases and the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of DSR for nodal metastases.
In 2020, Sarda-Inman et al., developed the Ultrasound Neck Node Reporting and Data System (UNN-RADS) scale that allows decision-making about when it is appropriate to perform FNA of a cervical lymph node, evaluating seven ultrasonographic descriptors (shape, margins, echogenicity, echogenicity of the hilum, vascularity and the presence/absence of calcifications, and cystic degeneration), features that have been associated with metastatic lymph nodes, with scores ranging from 0 to 3 points, which allows categorize into 5 different risk groups. Thus, the objective of this study is to evaluate the ultrasound characteristics of metastatic LN in patients undergoing TC follow-up and to validate the UNN-RADS scale for the diagnosis of LN Metastasis in Patients with a history of TC.
Aldosterone excess can cause oxidative stress leading to DNA damage in vitro and in vivo. Single case reports demonstrated a coincidence of primary aldosteronism (PA) with different malignancies. A higher prevalence of thyroid nodules and non-toxic multinodular goiter was described in patients with PA compared to those with essential hypertension (EH). A single study showed an association between PA and papillary thyroid cancer (PTC), but without a paired control group. Objective: To assess PA prevalence in a transversal cohort of patients with PTC and EH compared to a paired control group with HT.
Medullary thyroid carcinoma (MTC) is a tumor originating from parafollicular C cells of the thyroid. (1) Representing 1 to 7% of all thyroid carcinoma cases (2, 3, 4). It can occur in two clinical forms, the sporadic or non-hereditary, in 75-80% of patients, and the hereditary form in the remaining 20-25%. It can be part of different clinical syndromes depending on the organs involved: Multiple Endocrine Neoplasia type 2A (MEN2A), Multiple Endocrine Neoplasia type 2B (MEN2B) and Familial Medullary Thyroid Carcinoma (FCM) whose clinical expression is only CMT. A distinctive characteristic of this tumor is its capacity to secrete calcitonin (CT), which, measured in serum, sanctions suspicion of this pathology (5-8) leading to diagnostic studies to confirm CMT. For the preoperative diagnosis of thyroid nodules, ultrasound-guided fine-needle aspiration cytology (FNAC) is a useful and safe procedure; however, its sensitivity to exclude CMT is low (9-15). In 2015, a meta-analysis of 15 studies (16) found that the accuracy of FNAC in diagnosing CMT was around 50%. For this reason, other studies have indicated that the measurement of calcitonin in the fine-needle lavage aspirate fluid of thyroid nodules (CT-guided FNAC), which have suspected medullary carcinoma, can significantly improve the accuracy in the diagnosis of MTC (17 -19). Therefore, clinical practice guidelines recommend its determination in patients with suspected MTC (1,2). The diagnostic importance of pre-surgical medullary carcinoma lies mainly in two points: first, it changes the surgical approach of the patients, and second, it allows one to rule out associated pathologies such as hyperparathyroidism and pheochromocytoma, which are associated when the entity is hereditary. The performance of CT-guided FNAC by the chemiluminescent (CL) method has been widely disseminated. However, to the best of our knowledge, to date there are no data available on the appropriate cut-off value of CT-guided FNAC with calcitonin electrochemiluminescence (ECL) immunometric assay method. As previously stated, it is of particular interest to determine the calcitonin cut-off point in needle washing by electrochemiluminescence method that allows diagnosing medullary carcinoma. Clarifying this point allows improving the approach to patients in whom medullary carcinoma is suspected. This work seeks to determine the cut-off point of CT-guided FNAC for the diagnosis of CMT with the ECL assay method.
Tumor deposits (TD), nodules in the peritumoral adipose tissue with no architectural residue of lymph node, which is a definition often being confusing to the extranodal extension (ENE), have been described in several malignancies and linked to a worse prognosis. In gastric cancer and colon cancer, TD and ENE should be distinguished and collected separately in 8th AJCC manual. However, in thyroid cancer, TD as a collection variable was absence in both the 8th AJCC manual and the 2015 ATA guideline. This is a study that revealed the presence of TD by reviewing a large number of papillary thyroid carcinoma (PTC) specimens and explored its prognostic value by constructing a nomogram to accurately predict disease-free survival in PTC patients.
The goal of this retrospective study is to evaluate in patients with HCC and FTC who underwent lobectomy. The main questions it aims to answer are: - The necessity of completion thyroidectomy based on the clinicopathological characteristics - Prognosis Participants underwent thyroid lobectomy Researchers compared HCC and FTC groups to see the prognosis after lobectomy.
Papillary cancer is a disease that spreads through lymphatic ways and its treatment is surgery. We performed prophylactic central dissection in addition to bilateral total thyroidectomy in patients with bethesda 5 and bethesda 6 biopsy results. We evaluated the pathology results retrospectively.
Optimal surgical technique for neck dissection (LND) in thyroid carcinoma remains a subject of debate. Fascial ND (FND) implies the removal of the superficial and middle layers of the deep cervical fascia en bloc with lymph-nodes containing fibro-fatty tissue (levels IIa-Vb and VI-VII for cN1b patients). This retrospective cohort study was designed to compare FND with standard, non-fascial, selective ND (SND).
This is a prospective study aiming to establish near-infrared autofluorescence technology and PTH test strip as a standardized process for finding and identifying parathyroid glands in thyroid surgery.
The purpose of this study is to assess the effect of modified endotracheal intubation procedure combined with early oral intake on postoperative recovery quality of patients, so as to further optimize the ERAS（enhanced recovery after surgery） program for thyroid or parathyroid surgery.
