Metastatic Sigmoid Colon Malignancy With a Synchronous Carcinoma Breast: Is Cure Possible?

Srikanth Gadiyaram et al. Cureus. .

Abstract

Malignancies developing in two organs or more in the same patient are called multiple primary malignancies. They can be synchronous or metachronous based on the time of diagnosis of second cancer from the first. We encountered a synchronous stage IV sigmoid colon cancer (resectable liver metastasis) and breast cancer in a lady. The clinical dilemmas that arose with multiple primary malignancies and how they were tackled in our case have been discussed. A second malignancy should not deter the management or alter the clinical decision-making. Multidisciplinary teams are crucial to the management of these rare occurrences. We could successfully manage a synchronous breast and colon cancer with resectable liver metastasis at presentation.

Keywords: breast cancer; metastasis; multiple primary malignancies; sigmoid cancer; synchronous.
