Breast conservation therapy after augmentation mammaplasty: is it appropriate?

Area of Science:

• Oncology
• Surgical Oncology
• Radiotherapy

Background:

• Breast conservation therapy (BCT) is a popular breast cancer treatment option, offering survival rates equivalent to mastectomy for early-stage disease.
• Most BCT studies exclude patients with breast implants; data on BCT in augmented patients are limited.
• Silicone implants may complicate BCT outcomes and follow-up imaging.

Purpose of the Study:

• To evaluate the outcomes of breast conservation therapy in patients with silicone breast implants.
• To assess the incidence of complications and cosmetic results in augmented patients undergoing BCT.
• To determine the impact of implants and capsular contracture on mammographic surveillance after BCT.

Main Methods:

• Retrospective review of 33 augmented patients treated with breast conservation therapy between 1981 and 1994.
• Analysis of follow-up data for 26 patients, focusing on capsular contracture, cosmetic outcomes, and mammographic findings.
• Comparison of outcomes between augmented and nonaugmented patients where applicable.

Main Results:

• Significant capsular contracture developed in 17 (65%) of 26 augmented patients on the irradiated side.
• Cosmetic results were less satisfactory in augmented patients compared to nonaugmented women.
• Mammographic follow-up was potentially impaired by the presence of implants and capsular contracture.

Conclusions:

• Breast conservation therapy in augmented patients is associated with a high rate of capsular contracture and potentially compromised mammographic surveillance.
• Cosmetic outcomes are generally inferior in augmented patients undergoing BCT.
• Explantation of silicone implants prior to BCT may be advisable for augmented breast cancer patients to optimize outcomes and surveillance.
