Current management strategy of hypopharyngeal carcinoma

Objectives: Squamous cell carcinoma (SCC) of the hypopharynx represents a distinct clinical entity among other cancers of the head and neck region. Despite recent advances in chemoradiotherapy, surgery remains the preferred therapeutic option for locally advanced disease and salvage for failure after chemo-radiotherapy. In this article, several aspects of surgical and non-surgical approaches in the management of hypopharyngeal cancer are discussed. Methods: A search in pubmed was made for publications with regard to the management of hypopharyngeal carcinoma. Results: In early-staged hypopharyngeal cancer, the overall and disease-specific survival rates after organ-preserving radiotherapy is comparable to that after surgery. However, for advanced staged disease, the results initial surgery with post-operative adjuvant radiotherapy was superior to chemoradiotherapy alone. The incidence of occult nodal metastasis is found to be more than 20%. Selective neck dissection removing cervical lymph node level II-IV is the procedure of choice for patients with clinically NO neck. Contralateral nodal clearance may also be considered in tumors involving the medial wall of the pyriform recess, post-crioid region or the posterior wall, and those with ipsilateral palpable nodal metastasis and clinical stage IV disease. Transoral robotic surgery (TORS) has the potential value as the minimally invasive procedure for the management of carcinoma of the hypopharynx. Conclusions: The treatment strategy for carcinoma of the hypopharynx has been evolving with time. Organ preserving chemoradiotherapy has been the treatment of choice for early stage disease, with surgical resection and reconstruction reserved for advanced and recurrent tumors.
