Etiología de nódulos pulmonares en pacientes con cáncer mamario

Abstract

Materials and Methods: A case-series study was developed to describe the clinical, histological and anatomopathological characteristics of a sample of patients with a diagnosis of de novo metastatic breast cancer or whom presented with pulmonary nodules during their disease that required surgical resection by wedge pulmonary or lobectomy in the INC, between January 1, 2015 and April 30, 2018. Results: Fifty-five cases were included in the study period, of which 26 (47.3%) were breast cancer metastases, 9 (16.4%) were pulmonary primary second, and 1 (1.8%) patient had primary pulmonary cancer and one breast metastasis concomitantly. Another 2 (3.6%) patients had metastases from other organs, one from the rectum and one from the thyroid, while the remaining 17 (30.9%) patients presented a report of benign pulmonary lesions in the pathological anatomy. Conclusion: The presence of pulmonary nodules in patients with breast cancer are not always secondary to metastatic disease. Other etiologies may exist, such as primary pulmonary cancer, metastasis from other cancers, benign lung tumors or infections. Knowing the etiology of pulmonary nodules in patients with breast cancer is crucial to evaluate the therapeutic options .
