Abstract
Multiple primary malignant neoplasms occur relatively frequently today and are important especially in the head and neck area for they usually carry a bad prognosis. Detection of a synchronous primary tumor at the time of initial work-up is crucial both for management and final outcome. The first case was a T1 hypopharyngeal cancer with a mid-esophageal second primary who complained of a huge neck node. The second case was a T3 hypopharyngeal cancer who was initially seen by the chest surgeons for a large lower esophageal tumor. The third case was a patient previously operated for stomach adenocarcinoma three years ago, who had newly developed symptoms like dysphagia and hoarseness, and was diagnosed as hypopharyngeal T3 with oropharyngeal second primary cancer. Three cases were all heavy smokers and had histories of heavy alcohol consumption. They were all treated at the same sitting by en-block resection of the involved organs and postoperative radiation therapy. The authors have recently experienced 3 cases of synchronous second primary cancers in association with hypopharyngeal cancer and a report is made.
Key Words: Synchronous, Hypopharyngeal cancer
