Abstract

Purpose

Breast cancer surgical techniques are evolving. Few studies have analyzed national trends for the multitude of surgical options that include partial mastectomy (PM), mastectomy without reconstruction (M), mastectomy with reconstruction (M+R), and PM with oncoplastic reconstruction (OS). We hypothesize that the use of M is declining and likely correlates with the rise of surgery with reconstructive options (M+R, OS).

Methods

A retrospective cohort analysis was conducted using the ACS-NSQIP database from 2005 to 2016 and ICD codes for IBC and DCIS. Patients were then grouped together based on current procedural terminology (CPT) codes for PM, M, M+R, and OS. In each group, categories were sorted again based on additional reconstructive procedures. Data analysis was conducted via Pearson’s chi-squared test for demographics, linear regression, and a non-parametric Mann- Kendall test to assess a temporal trend.

Results

The patient cohort consisted of 256,398 patients from the NSQIP data base; 197,387 meet inclusion criteria diagnosed with IBC or DCIS. Annual breast surgery trends changed as follows: PM 46.3–46.1% (p = 0.21), M 35.8–26.4% (p = 0.001), M+R 15.9–23.0% (p = 0.03), and OS 1.8–4.42% (p = 0.001). Analyzing the patient cohort who underwent breast conservation, categorical analysis showed a decreased use of PM alone (96–91%) with an increased use of OS (4–9%). For the patient cohort undergoing mastectomy, M alone decreased (69–53%); M+R with muscular flap decreased (9–2%); and M+R with implant placement increased (20–40%)—all three trends p < 0.0001.

Conclusion

The modern era of breast surgery is identified by the increasing use of reconstruction for patients undergoing breast conservation (in the form of OS) and mastectomy (in the form of M+R). Our study provides data showing significant trends that will impact the future of both breast cancer surgery and breast training programs.
