Salvage Surgery in Recurrent Hypopharyngeal Carcinoma: Anobservational Single-institutional Study From 1998

Squamous cell carcinoma of the hypopharynx (HPSCC) is a rare but aggressive cancer, accounting for only 3-5% of all head and neck cancers. It occurs in the III-IV stage in about 60-85 % of cases, with 5-year overall survival (OS) ranging from 25 to 41%. It tends to spread in local submucosa, with an early involvement of the larynx and the locoregional tissue. Disease recurrence is around 15% to 40%, depending on the casuistry, the type of primary treatment (surgery vs. organ preservation protocols) and personal experience of each center. In recurrence setting, where indicated, salvage surgery (SS) remains the gold standard with the highest survival rates compared to conservative therapy. Generally patients are frail, with poor performance status and countless comorbidities and between 33% to 66% of cases are eligible to surgery with curative intent. In fact, in salvage setting the risk of peri-operative mortality is higher, postoperative complications are more frequent and hospital stay is longer.

Therefore, a careful selection of candidates is imperative and based on the following criteria: age and comorbidities, site of recurrence, stage, time interval since the first treatment and type of previous therapies
