Abstract

Purpose of Review

With improvements in imaging, breast cancers are diagnosed at earlier stages and increasingly, with additional findings of multifocal or multicentric disease. The aim of this review is to challenge existing paradigms that these scenarios can only be addressed with a mastectomy.

Recent Findings

Traditionally, multifocal or multicentric breast cancers have been addressed with a total mastectomy. Partial mastectomies have been attempted with the tacit understanding between patient and physician that the intervening tissue between cancer foci may contain cancer, and the safest oncologic decision would be to include the interposed tissue during surgical resection. More recent studies have refuted these long-held beliefs. This review is completed to bring to the fore the safety of breast conserving surgery in this population and data supporting this practice.

Summary

Multifocal and multicentric breast cancers can be surgically treated with breast conserving surgery, with no difference in oncologic outcomes if negative margins are obtained.

Ann Surg Oncol. 2022;29(1):427–36. https://doi.org/10.1245/s10434-021-10800-w. This Italian study is the most current data till date. The study follows retrospective matched cohorts of multicentric and multifocal cancer patients, treated with breast conserving surgery vs. mastectomy. This most recent iteration of the study reinforces that the outcomes for the two groups are similar, further strengthening the case for breast conservation in these patients.CrossRefPubMed Lorenzi De, et al.

Much like the TailorX study, age younger than 50 is found to be significant factor for Multifocal and Multicentric cancers and recurrence scores in addition to unifocal cancers.

The trend for multicentric cancers shows similar change but there is a lag in adapting this technique across various countries for a myriad of reasons. Masannat, et al.
