Head and Neck Cancer Pain
In the United States, there are 48,000 new cases of head and neck cancer (HNC) annually. Although HNC used to be associated mainly with smoking and drinking, it is now found in many nonsmokers and nondrinkers in their 50s due to the spread of HPV. Pain is typically present at the time of diagnosis. Treatment usually includes radiation, chemotherapy, and/or surgery, which address the mass effect and pain. Yet, patients continue to experience pain during and after treatment, because the treatment modalities can cause significant inflammation and neuropathy and can lead to central sensitization. Painful mucositis is a complication of chemotherapy and radiation treatment; it can become severe, impacting patients’ ability to speak and eat, and sometimes limiting treatment. Pain treatment for HNC is multimodal, and includes preemptive approaches to prevent neuropathy and central sensitization with antiepileptics, such as gabapentin and pregabalin. Mucositis pain is treated using a stepwise protocol.
