Abstract
Over a 10-year period, 790 patients with squamous cell carcinoma of the head and neck were treated at The Medical College of Wisconsin Affiliated Hospitals and were followed for a minimum of 7 years. Of the 218 patients with index primary laryngeal tumors, 43 (19.7%) developed additional malignancies in the head and neck, esophagus, or lung. Secondary lung tumors were the most common, occurring in 23 patients (10.6%). Of the 218 patients with index primary laryngeal carcinoma, 113 were treated successfully and never developed a recurrence of the original tumor. Twenty-one second primary lung malignancies developed in this group of successfully treated laryngeal tumor patients. The occurrence of these pulmonary malignancies was distributed fairly evenly over time. Three patients developed second primary lung tumors more than 7 years after initial treatment. The appearance of a second primary malignancy in the lung had a devastating effect upon survival. None of our patients survived more than 2 years after detection of the lung lesion. The relatively high incidence and delayed onset of second primary lung tumors in this group call into question the concept of 5-year “cures.” Our challenge for the future should be the prevention and early detection of these second primary lung tumors.
