title: Three cases of carcinoma of the hypopharynx developing as metachronous second primary cancers after total laryngectomy with radiotherapy for carcinoma of the larynx.
abstract: We describe 3 cases of metachronous hypopharyngeal cancer developing after laryngeal cancer had been treated with both radiotherapy and total laryngectomy. All 3 patients were men, 2 were 89 years old, and 1 was 65 years old. All patients had undergone total laryngectomy and radiotherapy for cancer for the glottis more than 20 years earlier. All patients underwent total hypopharyngectomy with jejunal free flap reconstruction. Surgery was complicated by scars from previous cancer treatment, and highly sophisticated surgical skills are needed, especially for preparing the recipient vessels. The postoperative period was largely uneventful and without fatal complications, however, 2 of the 3 patients died of distant metastasis 22 months and 31 months after surgery.
