Accuracy of fine-needle aspiration biopsy for predicting neoplasm or carcinoma in thyroid nodules 4 cm or larger.

Archives of Surgery, 2009
HYPOTHESIS All thyroid nodules 4 cm or larger should be surgically removed regardless of fine-needle aspiration biopsy (FNAB) results because of an unacceptably high rate of false-negative preoperative biopsy results in these large nodules.

Detection of PTEN Mutations in Fine Needle Aspiration Biopsies of Indeterminate Thyroid Nodules: Impact on Diagnosis and Prognosis

Head &Neck, EarlyView.
ABSTRACT Background Data connecting PTEN mutations with thyroid cancer risk for indeterminate nodules remain limited due to the rare nature of these mutations. The aim of this study was to determine the relationship between PTEN mutations identified in cytologically indeterminate nodules and final pathology and clinical outcomes.

Diagnostic value of fine-needle aspiration biopsy for breast mass: a systematic review and meta-analysis

BMC Cancer, 2012
Fine-needle aspiration biopsy (FNAB) of the breast is a minimally invasive yet maximally diagnostic method. However, the clinical use of FNAB has been questioned.

Bilateral Thyroid Ima Arteries Arising From the Brachiocephalic Trunk: A First Case Report

Head &Neck, EarlyView.
ABSTRACT Rationale Bilateral thyroid ima artery (TIA) arising from the brachiocephalic trunk is an extremely rare anatomical variation, with no prior cases reported. Recognizing such vascular anomalies is crucial for optimizing surgical outcomes in thyroid and mediastinal procedures, as failure to identify these variations can lead to severe ...

Cytokeratin 13 (CK13) expression in cancer: a tissue microarray study on 10,439 tumors

APMIS, Volume 131, Issue 2, Page 77-91, February 2023., 2023
Cytokeratin 13 (CK13) is a type I acidic low molecular weight cytokeratin, which is mainly expressed in urothelium and in the squamous epithelium of various sites of origin. Loss of CK13 has been implicated in the development and progression of squamous epithelial neoplasms. To comprehensively determine CK13 expression in normal and neoplastic tissues,

Diffusion-weighted MRI-guided needle biopsies permit quantitative tumor heterogeneity assessment and cell load estimation [PDF]

arXiv, 2021
Quantitative information on tumor heterogeneity and cell load could assist in designing effective and refined personalized treatment strategies. It was recently shown by us that such information can be inferred from the diffusion parameter D derived from the diffusion-weighted MRI (DWI) if a relation between D and cell density can be established ...

HPV‐Positive Squamous Cell Carcinoma Metastasis Without Clinical Evidence of Primary: The Posterior Oropharyngeal Wall May Be an Overlooked Location

Head &Neck, EarlyView.
ABSTRACT Background Oropharyngeal squamous cell carcinoma (SCC) can present as cancer of unknown primary, where only cervical lymph node metastases are identified. Most tumors, particularly human‐papillomavirus‐associated ones, are located in the palatine/lingual tonsils.

Diagnostic pitfalls in fine needle aspiration of solitary pulmonary nodules: two cases with radio-cyto-histological correlation [PDF]

, 2003
BACKGROUND: Fine needle aspiration is an important tool for diagnosis and preoperative evaluation of solitary nodules of the lung. It provides a definitive diagnosis in most patients at low cost with minimal trauma.
