Sudden cardiac death (SCD) is an unexpected death due to cardiac causes that occurs in a short time period (generally within 1 h of symptom onset) in a person with known or unknown cardiac disease. Patients with cardiomyopathies, myocarditis, ischemic heart disease and cardiac channelopathies are at risk of SCD. However, a certain percentage of autopsy-negative cases of SCD in the young (<35 years) remain unexplained even after a post-mortem genetic testing. Autoantibodies against cardiac proteins may be potentially involved in the pathogenesis of different heart diseases and in the occurrence of unexplained SCD...

The sinonasal tract is an environment diverse with neoplasia. Given the continued discovery of entities generally specific to the sinonasal tract, the fourth edition of the World Health Organization Classification of Head and Neck Tumors was released in 2017. It describes 3 new, well-defined entities and several less-defined, emerging entities. The new entities are seromucinous hamartomas, nuclear protein in testis carcinomas, and biphenotypic sinonasal sarcomas. Emerging entities include human papillomavirus-related sinonasal carcinomas, SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1-deficient sinonasal carcinomas, renal cell-like adenocarcinomas, and chondromesenchymal hamartomas...

BACKGROUND: Oropharyngeal squamous cell tumors associated with human papillomavirus infection (p16 positive tumors) have better prognosis than p16 negative tumors regardless of the more advanced stage of the disease. Tumor volume (GTVt+n) is generally an important factor affecting treatment results of ionizing radiation. The aim of this prospective non-randomized study is to evaluate the effect of tumor volume on the (chemo)radiation treatment results in a group of patients with p16 negative and p16 positive oropharyngeal tumors...

BACKGROUND: Penile cancer belongs to group of relatively rare malignancies. It represents, on average, 0.5-1% of all tumours in males globally and occurs predominantly in older individuals (&gt; 65 years). The geographical distribution of malignant cancer of the penis is reported. A higher incidence is observed in less developed parts of the world, particularly in South America, Southeast Asia, and some areas of Africa (&gt; 2.0/100,000). In Slovakia, there has been a recent increase in incidence (1...

BACKGROUND: A consensus about the most appropriate diagnostic method(s) for head and neck human papillomavirus (HPV)-induced carcinogenesis is still lacking because most of the commercially available assays have been designed for the cervix. METHODS: This article summarizes current data and trends concerning HPV diagnostic strategies in oropharyngeal squamous cell carcinoma (OPSCC). Six main approaches are described. RESULTS: The diagnostic gold standard for HPV-related OPSCC, focusing on E6/E7 mRNA detection, requires fresh samples...

AIMS: The International Endocervical Adenocarcinoma Criteria and Classification (IECC) was recently proposed as an improved method for categorising endocervical adenocarcinoma (EA) into human papillomavirus (HPV)-associated adenocarcinomas (HPVAs) and non-HPV-associated adenocarcinomas (NHPVAs). Such categorisation correlates with patient age and tumour size; however, its association with patient outcome remains to be established. METHODS: Institutional cases of EA with histological material available were selected...

BACKGROUND: Some studies have shown that human papillomavirus (HPV) is strongly associated with cervical cancer. As we all know, cervical cancer still remains the fourth most common cancer, affecting women worldwide. Thus, it is both challenging and essential to detect risk types of human papillomaviruses. METHODS: In order to discriminate whether HPV type is highly risky or not, many epidemiological and experimental methods have been proposed recently. For HPV risk type prediction, there also have been a few computational studies which are all based on machine learning (ML) techniques, but adopt different feature extraction methods...

Neck dissection (ND) is an essential component of treatment in head and neck squamous cell carcinoma (HNSCC). The extent of ND depends on primary tumor location and T and N stage. Trials have demonstrated improved survival for cN+ status with therapeutic ND as well as for cN0 status with selective ND if the primary has a high incidence of occult metastasis. The accuracy of the procedure is of prognostic relevance. In the prognostic model of the TNM classification, the parameter "N" does not only reflect the number of affected lymph nodes, but also their size and extranodal tumor extension...

Background: High-risk human papillomavirus (HPV) types are the main etiological factors for cervical cancer. HPV16 and HPV18 are generally the most common forms associated with development of high-grade cervical lesions. This study was undertaken to identify intratypic variants of HPV16 and HPV18 among women with cervical lesions in Tunisia. Materials and Methods: DNA was extracted from cervical samples collected from 49 women. using a PureLinkTM Genomic DNA mini Kit (Invitrogen). E6 and L1 open reading frames (ORF) were amplified by PCR and viral DNA amplicons were subjected to automated sequencing using Big Dye Terminators technology (Applied Biosystems)...

BACKGROUND: More than 400,000 cases of oropharyngeal squamous cell cancer (OPSCC) are diagnosed every year worldwide and this is rising. Much of the increase has been attributed to human papillomavirus (HPV). HPV-positive OPSCC patients are often younger and have significantly improved survival relative to HPV-negative patients. Traditional management of OPSCC has been with radiotherapy with or without chemotherapy, as this was shown to have similar survival to open surgery but with significantly lower morbidity...

Standardized, synoptic pathologic reporting for tumors greatly improves communication among clinicians, patients, and researchers, supporting prognostication and comparison about patient outcomes across institutions and countries. The International Collaboration on Cancer Reporting is a nonprofit organization whose mission is to develop evidence-based, universally available surgical pathology reporting data sets. Within the head and neck region, lymph node excisions and neck dissections are frequently performed as part of the management of head and neck cancers arising from the mucosal sites (sinonasal tract, nasopharynx, oropharynx, hypopharynx, oral cavity, and larynx), along with bone tumors, skin cancers, melanomas, and other tumor categories...

Background/Aims: Since patients with human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) have favorable outcomes after treatment, treatment de-escalation for these patients is being actively investigated. However, not all HPV-positive HNSCCs are curable, and some patients have a poor prognosis. The purpose of this study was to identify poor prognostic factors in patients with HPV-positive HNSCC. Methods: Patients who received a diagnosis of HNSCC and tested positive for HPV from 2000 to 2015 at a single hospital site (n = 152) were included in this retrospective analysis...

REVIEW
Keegan M Lyons, Samantha L Butler
Anal squamous cell carcinoma is a relatively rare diagnosis, but its incidence has continued to rise. Anal squamous cell carcinoma and its precursor lesion, anal intraepithelial neoplasia (AIN), are human papillomavirus (HPV)-associated squamous neoplasias. High-risk HPV subtypes cause cellular proliferation in the anal transformation zone mucosa leading to similar dysplastic changes as seen in the cervix. Unified cytologic and histologic classification systems have emerged for all HPV-associated squamous lesions of the lower anogenital tract due to recent advancements in the understanding of these lesions...

Histological grading of squamous intraepithelial lesions or intraepithelial neoplasia is fundamental for clinical management and for assessment of the risk of progression. Biomarkers are important for assisting correct grading of these lesions, reducing inter and intraobserver variability and most promising, for prognosis. Although p16 is the most studied biomarker in this setting, there are several other biomarkers that have been studied, reflecting also the need to find a better single or association option that can be more suitable, especially for classification purposes...

Locally advanced head and neck squamous cell carcinomas (HNSCC) have limited prognosis due to frequent treatment failure. Currently, TNM-classification and human papillomavirus (HPV) infection are the sole clinical prognosticators of outcome. Tumor heterogeneity and stemness based on epithelial-mesenchymal-transition reportedly associate with therapy resistance. The capacity of epithelial marker EpCAM (EpEX), stemness regulator Sox2 and mesenchymal marker vimentin to predict clinical outcome of HSNCC patients was assessed upon immunohistochemistry staining in two cohorts of HNSCC patients treated with surgery and adjuvant radio (chemo) therapy (n = 94) and primary radio (chemo) therapy (n = 94), respectively...

OBJECTIVE: Recently, the pattern of invasion in usual-type human papillomavirus-associated endocervical adenocarcinoma (AC) was put forward as a novel variable to select patients with favourable prognosis. Based on destructiveness of stromal invasion, three patterns were proposed: A - no destructive stromal invasion, B - focal destructive stromal invasion, and C - diffuse destructive stromal invasion. We aimed to independently validate the clinical significance of this classification-system in 82 AC patients, and explored associations between invasion pattern and somatic mutations...
