Treatment Options for Hypopharyngeal Cancer.

Abstract

Patients with hypopharyngeal cancer are difficult to treat because they typically present with advanced disease, poor general health status and severe nutritional problems. Currently, treatment options for previously untreated and newly diagnosed hypopharyngeal cancer patients include surgery of the primary tumour and lymph nodes metastasis, radiotherapy, systemic medical treatment, including traditional chemotherapy and immunotherapy. Currently, a multimodal treatment approach is preferred using surgery, radiotherapy and systemic therapy with curative intent and best supportive care in patients considered unfit for curative treatment or patients presenting with distant metastatic spread. More detailed topics regarding the choice of treatment include biological and immunological host factors and their use for defining individualised cancer care, integration of novel therapies, integration of patient autonomy into clinical reasoning and dealing with patients' trade-offs between oncological outcome and individual quality of life, local availability of diagnostic therapeutic procedures and volume-outcome relationships for head and neck cancer surgery, radiotherapy and specialised supportive care. They also include considerations regarding potential delay between diagnosis and treatment, and between different treatment modalities within the frame of multimodal therapy. To date only one randomised trial comparing surgical versus non-surgical approaches has been published. Most randomised trials dealing with hypopharyngeal cancer compare different chemo- and radiotherapy regimen, but do not compare with a surgical approach. On the other hand, most studies on the results of surgery are best considered to be of low-quality case series. At the same time, many of the chemotherapy and radiation oncology studies in head and neck cancer include patients with different primary sites, where hypopharyngeal cancer patients when included usually account for a minority of the study population. Therefore, choosing the best treatment for an individual patient with hypopharyngeal cancer relies on personal experience and local expertise of the multidisciplinary team involved in the therapeutic process.
