Breast-conserving therapy can be offered to women with prior breast augmentation.

Breast cancer in women with cosmetic breast implants is increasingly common. Over the past decade, there has been a push for mastectomy and reconstruction in these patients, based on a fear of poor aesthetic results from small breast volume, and radiation-induced capsular contracture. At the Paris Breast Centre, augmented women routinely undergo lumpectomy with whole-breast irradiation (BCT). A consecutive cohort of 50 augmented women, who had attempted BCT for early breast cancer at our institution between 2003 and 2018, were retrospectively identified. Post-treatment complications, oncologic outcomes, capsular contracture rates, long-term cosmetic outcomes, and patient-reported outcomes were evaluated. The median follow-up was 51 months. Margins were involved in 7 women (14%); 4 of whom underwent successful re-excision, and 3 had a mastectomy, for an early mastectomy rate of 6%. There were no early complications, nor cases of early implant loss. Long-term aesthetic results were evaluated using our 5-point scale: An excellent (5), or good (4) result was obtained in 68%. Significant capsular contracture (Baker grade 3 or 4) developed in 34%, of which, 5 women underwent capsulotomy and fat grafting; 4 of 5 downstaging their Baker grade. The estimated 5-year local recurrence rate was 2.3%. Ninety-five percent of participants would recommend BCT to augmented women. BCT is feasible and safe in augmented women with good long-term aesthetic results, and should be considered to avoid unnecessary mastectomy.
