BACKGROUND: This study presents oncologic outcomes after transoral robotic surgery (TORS) ± adjuvant therapy for oropharyngeal squamous cell carcinoma (SCC). METHODS: Three hundred fourteen patients undergoing TORS ± adjuvant therapy for oropharyngeal SCC from May 1, 2007, to May 31, 2015, are analyzed. RESULTS: Median follow-up was 3.3 years (interquartile range [IQR] 1.8-5.3 years; range 1 day to 9.3 years). Estimated locoregional recurrence-free survival, distant metastasis-free survival (DMFS), overall survival (OS), and cancer-specific survival (CSS) rates (95% confidence interval [CI] number still at risk) at 5 years after surgery were 92% (88-95; 92), 90% (86-94; 92), 86% (82-92; 98), and 94% (91-97; 98), respectively...

To know tumor PD-L1 expression through IHC or the FDG-PET related radiomics, we investigated the association between programmed cell death protein 1 ligand (PD-L1) expression and immunohistochemical (IHC) biomarkers or textural features of 18F-fluoro-2-deoxdeoxyglucose positron emission tomography (18F-FDG PET) in 53 oropharyngeal or hypopharyngeal cancer patients who were ready to undergo radiotherapy-based treatment. Differences in textural features or biomarkers between tumors with and without PD-L1 expression were tested using a Mann-Whitney U test...

Pigmented squamous cell carcinoma in situ (PSCCIS) is very rare, being clinically described as a pigmented lesion with histological characteristics of an in-situ carcinoma presenting pigmentation within neoplastic cells. A 50-year-old Afro-descendant man came for clinical evaluation of a painful black and red lesion located on the right aspect of the oropharyngeal isthmus. After incisional biopsy, the resulting sample was described as a pigmented squamous cell carcinoma in situ, a diagnosis further confirmed by immunohistochemical analysis...

The staging of oropharyngeal squamous cell carcinoma has undergone key changes in the eighth edition of the American Joint Committee on Cancer Staging Manual, set to take effect January 1, 2018. The most significant change relates to the development of a novel staging system for human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinomas, distinct from that for non-HPV-associated squamous cell carcinomas of the oropharynx. We describe the revised staging parameters and the rationale in support of the changes...

Head and neck cancer (HNC) remains the sixth most common malignancy worldwide and survival upon recurrence and/or metastasis remains poor. HNSCC has traditionally been associated with alcohol and nicotine use, but more recently the Human Papilloma Virus (HPV) has emerged as a favorable prognostic risk factor for oropharyngeal HNSCC. However, further stratification with additional biomarkers to predict patient outcome continues to be essential. One candidate biomarker is the DEK oncogenic protein, which was previously detected in the urine of patients with bladder cancer and is known to be secreted by immune cells such as macrophages...

Histoplasma capsulatum, a dimorphic fungus found world-wide, is endemic to regions of the Mississippi and Ohio River valleys and portions of Central and South America. Initial infection can present with acute pulmonary symptoms or remain clinically asymptomatic, with disease course generally guided by degree of inoculum and underlying immunosuppression. A chronic, progressive course of weight loss, oral ulceration, and fatigue has been associated with elderly males. We present a 79-year-old man with a chronic, progressive course of oral lesions, odynophagia, and weight loss who was found to have histoplasmosis on oral biopsy performed for suspicions of oropharyngeal squamous cell carcinoma...

Oral squamous cell carcinomas are a major cause of morbidity and mortality, and tobacco usage, alcohol consumption, and poor oral hygiene are established risk factors. To date, no large-scale case-control studies have considered the effects of these risk factors on the composition of the oral microbiome, nor microbial community associations with oral cancer. We compared the composition, diversity, and function of the oral microbiomes of 121 oral cancer patients to 242 age- and gender-matched controls using a metagenomic multivariate analysis pipeline...

BACKGROUND: The emergence of transoral robotic surgery (TORS) ignited the debate between surgical and nonsurgical strategies on oropharyngeal squamous cell carcinoma (SCC) management; a question further complicated by human papillomavirus (HPV). We evaluated the survival by treatment strategy independently in HPV-related and HPV-nonrelated oropharyngeal SCC. METHODS: The National Cancer Database was queried for patients with oropharyngeal SCC with known HPV status who underwent primary TORS or primary radiotherapy...

The favorable features of high-risk human papillomavirus (HPV) in the head and neck are limited to those harboring transcriptionally-active HPV, which occur predominantly in the oropharynx (OP). Factors rendering the OP susceptible to HPV oncogenesis are largely unexplored. The role of cytokeratin 7 (CK7) in predisposition to HPV and cancer in the cervix has been evaluated. However, its significance in the H&N is unknown. CK7 immunohistochemistry was performed on a tissue microarray cohort of OP and non-oropharyngeal (NOP) squamous cell carcinomas (SCC) with known clinical follow-up and HPV E6/7 mRNA status...

We conducted a critical review of human papillomavirus (HPV) integration into the host genome in oral/oropharyngeal cancer, reviewed the literature for HPV-induced cancers, and obtained current data for HPV-related oral and oropharyngeal cancers. In addition, we performed studies to identify HPV integration sites and the relationship of integration to viral-host fusion transcripts and whether integration is required for HPV-associated oncogenesis. Viral integration of HPV into the host genome is not required for the viral life cycle and might not be necessary for cellular transformation, yet HPV integration is frequently reported in cervical and head and neck cancer specimens...

In the last years, the explosion of high throughput sequencing technologies has enabled epigenome-wide analyses, allowing a more comprehensive overview of the oropharyngeal squamous cell carcinoma (OPSCC) epigenetic landscape. In this setting, the cellular pathways contributing to the neoplastic phenotype, including cell cycle regulation, cell signaling, DNA repair, and apoptosis have been demonstrated to be potential targets of epigenetic alterations in OPSCC. Of note, it has becoming increasingly clear that HPV infection and OPSCC lifestyle risk factors differently drive the epigenetic machinery in cancer cells...

BACKGROUND: Oral and oropharyngeal carcinomas representing about 90% of all oral malignancies are the sixth most common cancers worldwide. Basic modalities of cancer treatment are surgery, radiotherapy, and chemotherapy (CT) either alone or in combination. For squamous cell carcinoma (SCC) patients, induction CT followed by radiotherapy and concurrent CT are effective methods for improving response rates. MATERIALS AND METHODS: Fifty patients with advance stage oral cavity cancer with performance status >60% on Karnofsky performance scale and having no prior exposure to CT, radiotherapy, and surgery were included in the study...
