Anal squamous cell carcinoma (SCC) is the fourth most prevalent cancer in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Human papillomavirus (HPV) has been detected in over 90% of anal carcinoma biopsy specimens from MSM, and is considered a necessary, but alone, insufficient factor for carcinogenesis. Anal intraepithelial neoplasia (AIN) may be precursive for SCC, and screening cytology with referral of persons with abnormality for high-resolution anoscopy-guided biopsy, and AIN treatment, has been recommended for prevention...

Papillary squamous neoplasms of the upper respiratory tract are rare variants of squamous cell carcinomas. They are characterised by an exophytic, papillary growth and generally have favourable prognosis. The tumour has been described in the upper aerodigestive tract. In this context, most common sites of involvement are the larynx and hypopharynx, and rarely the oral cavity and oropharynx. The limited studies and small number of published cases of papillary squamous cell carcinoma of the palatine tonsil led us to make a complete analysis of this tumour by analysing the clinical, histological, radiological, virological and therapeutic aspects that are not always present in the literature...

GOAL: To investigate the HPV prevalence and characterize the expression of potential molecular surrogate markers of HPV infection in esophageal squamous cell carcinoma. MATERIALS AND METHODS: The prevalence of HPV in individuals with and without esophageal cancer (EC) was determined by using multiplex PCR; p16 and p53 protein levels were assessed by immunohistochemistry (IHC). RESULTS: High-risk HPV (hr-HPV) was found in the same frequency (13.8%) in esophageal squamous cell carcinoma (ESCC) and in healthy individuals...

Human papillomaviruses are small DNA viruses with a tropism for squamous epithelia. A unique aspect of human papillomavirus molecular biology involves dependence on the differentiation status of the host epithelial cell to complete the viral lifecycle. A small group of these viruses are the etiologic agents of several types of human cancers, including oral and anogenital tract carcinomas. This review focuses on the basic molecular biology of human papillomaviruses.

The performance characteristics of neuroendocrine-specific and squamous-specific immunohistochemical markers in head and neck squamous cell carcinomas (SCC), in particular in oropharyngeal tumors in this era of human papillomavirus (HPV)-induced cases, are not well-established. The differential diagnosis for poorly differentiated SCCs, for nonkeratinizing oropharyngeal SCCs, and for other specific SCC variants such as basaloid SCC and undifferentiated (or lymphoepithelial-like) carcinomas includes neuroendocrine carcinomas...

Squamous cell carcinoma of the head and neck (SCCHN) is the sixth most common cancer worldwide. It has recently been appreciated that human papillomavirus (HPV) status (or p16 status, which is a frequently used surrogate for HPV status) is prognostic for oropharyngeal SCCHN. Here, we review and contextualize existing p16 and HPV data, focusing on the cetuximab registration trials in previously untreated, locoregionally advanced, nonmetastatic SCCHN (LA SCCHN) and in recurrent and/or metastatic SCCHN (R/M SCCHN): the IMCL-9815 and EXTREME clinical trials, respectively...

Recurrent respiratory papillomatosis (RRP) is a disease of the respiratory tract caused by infection with the human papillomavirus (HPV) and is characterized by multiple recurring papillomas throughout the respiratory tract. Although rare, extra laryngeal involvement carries the risk of malignant transformation in 3-7% of adults. We report the case of a patient with unmonitored juvenile onset RRP with pulmonary involvement found to have malignant transformation to squamous cell carcinoma (SCC). Incidentally found on chest radiography for mild chest wall trauma, she was found to have a large left lower lobe mass with pathology consistent with SCC...

Purpose: We previously demonstrated an association between decreased SMAD4 expression and cetuximab resistance in head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to further elucidate the clinical relevance of SMAD4 loss in HNSCC. Experimental Design: SMAD4 expression was assessed by immunohistochemistry in 130 newly diagnosed and 43 recurrent HNSCC patients. Correlative statistical analysis with clinicopathological data was also performed. OncoFinder, a bioinformatics tool, was used to analyze molecular signaling in TCGA tumors with low or high SMAD4 mRNA levels...

The identification of molecular targets in the therapy of human papilloma virus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) is a primary aim of cancer research. Matrix metalloproteinase 9 (MMP-9) and vascular endothelial growth factor receptor (VEGFR) have important roles in the development of HNSCC. The tyrosine kinase inhibitors, nilotinib, dasatinib, erlotinib and gefitinib are well established in the targeted therapy of tumors other than HNSCC. The present study aimed to investigate the alteration of MMP-9 and VEGFR-1 expression patterns following treatment with these tyrosine kinase inhibitors in p16-positive and -negative squamous carcinoma cells...

BACKGROUND: The p16Ink4a is not a surrogate marker for high-risk human papilloma virus (HPV) genotypes but indicates better prognosis in vulvar squamous cell carcinoma patients. Our recent study confirmed substantial mismatch between p16Ink4a and high-risk HPV-status as well as revealed that p16Ink4a-overexpression itself is an independent prognostic factor for vulvar cancer. AIM: To determine significance of the tumor infiltrating immune cells and p16Ink4a-status for better outcome of patients with vulvar cancer...

Basaloid Squamous Cell Carcinoma (BSCC) is a rare entity with its histopathological distinction from conventional squamous cell carcinoma. It is frequently considered a high-grade carcinoma with poor prognosis because of higher rate of distant metastases. Here by, we are reporting a case of 39-year-old male with an ulcer on the left lateral border of the tongue since a month. Histopathological examination of incisional biopsy revealed basaloid tumour cell islands accompanied by component of well differentiated squamous cell carcinoma...

REVIEW

Anal squamous cell carcinomas (ASCC) are increasing in frequency across the developed world, and 70-90% of all cases originate from infection with human papilloma viruses (HPV). Primary chemoradiotherapy (CRT) is the standard treatment for ASCC, but local and/or distant failure still occurs in up to 30% of patients. HPV-associated ASCC and tumors with a higher density of tumor infiltrating lymphocytes (TIL) carry a better prognosis. Furthermore, HPV can render tumors more immunogenic, whereas it correlates with elevated TIL densities...

BACKGROUND: Biomarkers that facilitate the prediction of disease recurrence in head and neck squamous cell carcinoma (HNSCC) may enable physicians to personalize treatment. In the current study, DNA promoter methylation of programmed cell death 1 (PDCD1, PD-1) was evaluated as a prognostic biomarker in HNSCC patients. RESULTS: High PDCD1 methylation (mPDCD1) was associated with a significantly shorter overall survival after surgical resection in both the discovery (HR = 2...
