Experts release new guidelines for studies into most effective treatments for HPV-positive throat cancer
Source: en.brinkwire.com Author: provided by University of Birmingham, United Kingdom Heightened caution is needed when considering de-escalation trials for patients with Human papillomavirus (HPV)-positive oropharyngeal cancer (OPC), to ensure minimal harm to patients, new guidelines from a group of international head and neck cancer experts have suggested. HPV-positive oropharyngeal cancer is a cancer of the throat caused by the human papillomavirus—a common, but symptomless group of sexually transmitted viruses. Instances of many throat and neck cancers have declined as smoking rates have fallen, whereas HPV-positive OPC has increased, largely affecting younger patients. The standard course of treatment for this disease is a combination of cisplatin (a common chemotherapy drug) and radiotherapy. The younger age of the patient population, significantly improved prognosis, and relatively minimal morbidities caused by the standard treatment pathway have led to the popularisation of the concept of treatment de-escalation as a way to improve the quality of life of patients by reducing dosage or frequency of treatment. These new recommendations, published today in the Journal of Clinical Oncology have been created by the Head and Neck Cancer International Group, a group of experts from nineteen countries, led by the University of Birmingham, UK. The guidelines have been prompted by the recent results of the first three randomised de-escalation trials which suggested a clear detriment in survival when cisplatin is omitted or substituted to minimise side effects. After a review of available HPV-positive OPC literature, the guidelines recommend an overall need for caution when considering de-escalation options, even [...]
