BACKGROUND: Human immunodeficiency virus-infected individuals (HIVIIs) have a higher incidence of head and neck squamous cell carcinoma (HNSCC), and clinical and histopathological differences have been observed in their tumors in comparison with those of HNSCC patients without a human immunodeficiency virus (HIV) infection. The reasons for these differences are not clear, and molecular differences between HIV-related HNSCC and non-HIV-related HNSCC may exist. This study compared the mutational patterns of HIV-related HNSCC and non-HIV-related HNSCC...

Cytologic sampling is the mainstay of diagnosing advanced lung cancer. Moreover, to select patients for personalized first-line or second-line treatment, epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) rearrangements are tested on cytologic preparations. Commercially available fluorescence in situ hybridization (FISH) and immunocytochemistry (ICC) assays have primarily been used for the identification of cells harboring ALK or ROS1 gene fusions on histologic rather than cytologic preparations...

BACKGROUND: Fine-needle aspiration (FNA) cytology of salivary glands is a well-established technique that plays a critical role in the preoperative diagnosis of lesions. A risk stratification of FNA diagnostic categories has been recently proposed to be useful in reporting. The aims of this study were to evaluate the diagnostic accuracy of salivary gland FNA and to apply the proposed Milan system for reporting salivary gland lesions. METHODS: A retrospective audit of FNA specimens of salivary gland lesions reported from 2014 to 2016 was performed...

Non-small cell lung cancer is a different disease from what it was a decade ago. The last 10 years were based on remarkable advances in the understanding of key genetic alterations that function as oncogenic drivers and serve as therapeutic targets, thereby defining new molecular subsets. These changes have had an impact on clinical care, patient outcomes, and pathologic diagnosis and present new challenges in the approach of the cytopathologist to this still deadly disease. To meet these new challenges and appropriately train the next generation of cytopathologists, the complex molecular background underlying this disease and the implications that cytologic and histologic diagnoses have on treatment must be understood...

BACKGROUND: Thyroid nodules with atypia of undetermined significance (AUS) on fine-needle aspiration (FNA) have a low risk of malignancy that appears to vary based on specific features described in the AUS diagnosis. The Afirma gene expression classifier (GEC) is a molecular test designed to improve preoperative risk stratification of thyroid nodules, but its performance for different patterns of AUS has not been defined. The objective of this study was to assess GEC results and clinical outcomes in AUS nodules with architectural atypia (AUS-A), cytologic atypia (AUS-C) or both (AUS-C/A)...

BACKGROUND: NUT midline carcinoma (NMC) is an increasingly recognized neoplasm defined by rearrangements of the nuclear protein in testis (NUT) gene (also known as NUTM1). NMC is important to diagnose for prognostic and diagnostic reasons, but to date, only a small case series and rare case reports of the cytopathologic features of NMC have been published. METHODS: All NMC specimens (confirmed by molecular testing and/or NUT immunoreactivity) with cytopathologic material available were identified at 2 academic centers...

BACKGROUND: Fine-needle aspiration (FNA) cytology is accurate and cost-effective in the evaluation of thyroid nodules. Molecular techniques may contribute to risk stratification in indeterminate cases. Although next-generation sequencing (NGS) is a promising technique for the molecular testing of thyroid FNA specimens, thyroid-specific cancer gene panels are not commercially available. Conversely, the Ion AmpliSeq Cancer Hotspot Panel v2 (CHPv2), which includes the genes most frequently mutated in thyroid neoplasms, is commercially available and may represent an alternative to thyroid-specific panels...

BACKGROUND: "The Paris System" proposes a 7-tier classification system for urine cytology. Establishing the risk of malignancy (ROM) associated with these diagnostic categories is essential to determine the appropriate management of patients. The objective of this study was to determine the ROM associated with the "positive" and "suspicious" categories. METHODS: The authors searched their electronic records for urine cytology specimens that had been diagnosed as "positive" or "suspicious" for high-grade urothelial carcinoma within an 11-year time frame...

BACKGROUND: Pelvic endoscopic ultrasound-guided fine-needle aspiration (PEUS-FNA) of rectal or perirectal lesions is safe, minimally invasive, and well tolerated. It provides valuable information, which can greatly influence patient management. Herein, the authors present what to their knowledge is the largest series to date of PEUS-FNA. METHODS: PEUS-FNA specimens were retrieved from the archives of the study institution from January 2001 to March 2015. Only patients with solid pelvic lesions were examined...

BACKGROUND: Thyroid malignancy is rare in young children, although the incidence increases sharply during adolescence. Nodular thyroid disease and thyroid cancer in children differ substantially from those in adults, because the rates of malignancy among children are roughly 5-fold higher, and local and distant metastases as well as recurrences are more common. Even with the recent introduction of pediatric guidelines, there remains a paucity of pediatric data on which to base clinical decision making...

BACKGROUND: Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) often presents with cystic cervical metastasis and a small primary tumor localized in the palatine tonsils or base of the tongue, which is diagnostically challenging. Testing for HPV DNA in fine-needle aspiration (FNA) smears from metastases may facilitate a targeted diagnostic workup for identifying the primary tumor. This study was designed to assess the ability to detect HPV DNA in FNA smears with polymerase chain reaction (PCR)...

BACKGROUND: Cytology is an accurate, safe, cost-effective, and guideline-recommended method for pancreatic cancer diagnosis, particularly for unresectable disease. However, to the authors' knowledge, the frequency and determinants of its use have not been described to date. The current study examined patterns of cytological diagnosis among patients with unresectable pancreatic cancer by treatment facility type and by patient characteristics. METHODS: The prevalence of definitive cytological diagnosis (cytology only, without confirmatory histology) versus histological diagnosis (with or without accompanying cytology) was examined in National Cancer Data Base records of 13,657 patients diagnosed with unresectable (American Joint Committee on Cancer stages III and IV) pancreatic cancer in 2011 and 2012 who did not undergo surgical treatment (mode of diagnosis could not be ascertained for surgical patients)...

BACKGROUND: The use of minimally invasive procedures in autopsies such as image-guided fine-needle aspiration may facilitate family acceptance and, therefore, increase the number of postmortem examinations. The objective of the current study was to validate the use of cytology in a prospective set of conventional autopsies. METHODS: All lesions and organs sampled for histological examination were concomitantly evaluated by scrape cytology of exactly the same location...

BACKGROUND: Molecular analysis represents an increasingly important component of the pathologic examination of tumor specimens. Notably, the characterization of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression in breast cancer specimens provides critical prognostic and predictive information. The objective of the current study was to compare the concordance of these markers as determined on fine-needle aspiration (FNA) cell blocks compared with tissue blocks prepared from surgical specimens...

BACKGROUND: The Afirma gene expression classifier (GEC) assesses malignancy risk in patients with indeterminate thyroid nodules. Afirma putatively reduces costs by classifying certain nodules as benign and thereby avoiding unnecessary surgery. Prior studies have evaluated its impact exclusively on GEC-tested nodules. The objective of the current study was to analyze the effect of Afirma on 1) cytopathology diagnosis, 2) the rate of surgery, and 3) the rate of malignancy on all indeterminate nodules at a high-volume thyroid center...
