title: Three synchronous multiorgan primary cancers. All stage I.
abstract: A patient who has three separate, synchronous, early (stage I) primary cancers of the right lung, right breast, and stomach and whose disease is simultaneously diagnosed and successfully treated sequentially within a single hospital admission is unique. While multiple primary malignant neoplasms are not uncommon, to our knowledge, there has been no report of triple stage I synchronous carcinomas in separate major organ systems. Age, immunodeficiency, somatotype, hereditary tendencies, hormonal and environmental factors, and previous therapy have been incriminated as etiologic factors. Accurate tissue diagnosis and tumor staging are mandatory. In patients with diagnosed cancer, pulmonary lesions should never be presumed metastatic. Individual tumors should be treated independently of other concomitant lesions, and each treatment approach should be curative in nature. Patients with proven multiple malignant neoplasms carry a higher risk of developing other primary neoplasms.
