In a series of more than 2500 patients with cervical carcinoma who were regularly surveyed after treatment, ten cases of bronchial carcinoma confirmed by biopsy were found. The mean delay between the diagnosis of the cervical carcinoma and bronchial carcinoma was 28 months. This long interval, particularly when there was no distant metastases, raises questions about whether bronchial metastasis of cervical carcinoma or a second primary occurred. Comparisons with data of population cancer registries argue in favor of metastasis.
