Palliation of bronchogenic carcinoma with 198Au implantation using the fiberoptic bronchoscope.

ABSTRACT

The majority of cases of bronchogenic carcinoma remain incurable, and many of these patients require palliation of the effects of the tumor on the airway. We have developed a technique for implanting radioactive (198Au) seeds via the fiberoptic bronchoscope. We now retrospectively review the results obtained in 111 procedures in 54 patients. Response was assessed by improvement in symptoms, chest roentgenogram, or bronchoscopic appearance. Nineteen of 29 (66 percent) patients with occluding endobronchial lesions benefitted. Twenty of 22 (91 percent) with hemoptysis improved. All six patients with tracheal lesions benefitted. Two of six (33 percent) patients with nonoccluding endobronchial lesions responded. Complications directly related to the procedure were rarely of major consequence, although a single patient had an exsanguinating hemoptysis four days following the last of multiple implantations. The simplicity, relative safety, and potential wide availability coupled with low equipment costs would suggest an increasing role for this technique in the palliation of endobronchial neoplasms.
