Summary of "Advances in Diagnosis and Multidisciplinary Management of Oropharyngeal Squamous Cell Carcinoma: State of the Art."

During the past decade and a half, the most common cause of oropharyngeal squamous cell carcinoma (OPSCC) has shifted from tobacco and alcohol to the human papillomavirus (HPV). HPV-driven p16-positive OPSCC and tobacco-related OPSCC differ in their underlying molecular and genetic profiles, socioeconomic demographics, and response to treatment. HPV-related OPSCC tends to occur in younger patients and has a significantly better response to treatment and excellent prognosis. The stark contrast in prognosis-with around 90% overall 5-year survival for HPV-related p16-positive OPSCC and 40% for non-HPV-related p16-negative OPSCC-has prompted major changes in the eighth edition of the staging manual of the AJCC (American Joint Committee on Cancer). The past 10-15 years have also witnessed major advances in surgery, radiation therapy (RT), and systemic therapy. Minimally invasive surgery has come of age, with transoral robotic procedures and laser microsurgery. Intensity-modulated RT (IMRT) and more recently proton-beam RT have markedly improved the conformity of RT, with an ability to precisely target the cancer and cancer-bearing regions while sparing normal structures and significantly reducing long-term treatment-related morbidity. Progress in systemic therapy has come in the form of immunotherapy and targeted agents such as cetuximab. Owing to the better prognosis of HPV-driven OPSCC as well as the morbidity associated with treatment, de-escalation of therapy via multiple strategies is being explored. The article reviews the advances in diagnosis and multidisciplinary management of OPSCC in the HPV era.RSNA, 2019.

Medical and Biotech [MESH] Definitions

A carcinoma derived from stratified squamous epithelium. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.

A mixed adenocarcinoma and squamous cell or epidermoid carcinoma.

Unusual tumor affecting any site of the body, but most often encountered in the head and neck. Considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. It affects women more often than men. When it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma.

A skin carcinoma that histologically exhibits both basal and squamous elements. (From Dorland, 27th ed)
