A Case of Colonic and Cardiac Metastases from Breast Cancer that Occurred 19 Years After Surgery

Abstract

Resection of multiple organ metastasis of breast cancer is rare. We experienced a case of breast cancer with resection of metachronous metastases to the colon and heart.

The case was a 76-year-old woman with a complaint of epigastric pain. Nineteen years ago, she had undergone radical mastectomy for right breast cancer. Endoscopic examination revealed a stenosis in the transverse colon which was diagnosed by a biopsy specimen as metastasis from breast cancer. Enhanced CT scan revealed a mass of the right ventricle which was suspected to be cardiac metastasis. We decided on surgical resection initially, and performed laparoscopy assisted colectomy for resection of the transverse colon in September 2021. Pathological diagnosis was colonic metastasis from breast cancer. After discharge, she underwent adjuvant therapy. Because the cardiac tumor had grown, cardiac tumor was resected at another hospital in January 2022. Pathological diagnosis was cardiac metastasis from breast cancer. She had no recurrence for 14 months after colectomy.
