Systemic Therapy, Palliation and Supportive Care of Patients with Hypopharyngeal Cancer

Abstract

Hypopharyngeal cancer patients have a very poor prognosis and limited therapeutic options. Seventy to eighty per cent of all hypopharyngeal cancer patients will require palliative and/or end-of-life care for incurable end-stage disease during the course of their illness. The overall proportion of hypopharyngeal cancer patients not qualifying for initial curative treatment, or requiring palliation and supportive care over time is higher than for any other subsite of the head and neck. Surgery and radiotherapy usually have a very limited role in this setting, while systemic therapy will usually compete with supportive care as the best approach. Advances in medicine and oncological treatments for the management of patients with recurrent head and neck cancer have given physicians the opportunity to prolong life where possible. However, this increase in survival might not be clinically meaningful if patients do not simultaneously experience palliative benefits, such as a reduction in symptoms and an improvement in their overall quality of life (QoL). The optimal outcome of palliative treatment is the control of symptoms with minimal treatment toxicities while improving QoL. It remains unclear if current palliative treatment options are better at improving QoL than the best supportive care. An intervention that results in insufficient or unacceptable functional status to the extent that the patient cannot achieve treatment goals - even in the course of prolonging life - is questionable. When used for palliative care purposes, surgery, chemotherapy and radiotherapy commonly have limited effectiveness in improving QoL. Moreover, if these treatments are not congruent with a patient's end-of-life goals, they could constitute low-value care.
