BACKGROUND: Postmastectomy Radiotherapy (PMRT) has become standard of care for patients with breast cancer. However, local recurrence following breast conserving therapy is increasing in incidence due to increased survivorship. The relationship between prior radiation therapy, PMRT and immediate breast reconstruction (IBR) outcomes has not been widely studied. We aim to assess factors that correlate with post-IBR complications in the face of radiation therapy.
METHODS: An IRB approved retrospective cohort review of 262 patients was completed using our tumor registry to identify female patients age ≥ 18 with and without history of radiation who underwent mastectomy with IBR. Operative, clinical, and pathological data was collected, and univariate and multiple logistic regression analyses were conducted to evaluate the relationship between receipt of radiation and major and minor complications. Kaplan-Meier analysis was also conducted to assess the differences between the time to receipt of radiation and cancer recurrence amongst the 3 treatment groups.
RESULTS: There was no correlation between major or minor complications and a history of prior radiation. Patients with PMRT demonstrated a higher incidence of "other" minor complications (OR 2.8, CI 1.27-6.28, P = .01), such as erythema and edema. There was a higher incidence of implant exposure requiring reoperation (OR 5.7, CI 1.36-23.78, P = .01) and "other'' minor complications (OR 3.1, CI 1.32-7.35, P < .001) in patients with PMRT. Receipt of PMRT was associated with lower survival in compared to patients with no history of radiation treatment.
CONCLUSION: Our study found no significant associations between history of prior radiation and surgical complications after mastectomy and IBR. However, patients with PMRT were at increased risk of developing minor complications requiring reoperation. This suggests that we should discuss radiation concerns preoperatively and manage expectations regarding its effect on outcome.
