Upper Extremity Functional Outcomes After Breast Cancer Treatment: An Analysis of DASH Score in Breast Reconstruction
Background:
Patients undergoing postoncologic breast reconstruction can experience upper extremity (UE) functional deficits.
Objectives:
In this study, we utilized the disabilities of the arm, shoulder, and hand (DASH) questionnaire to identify patient factors that impacted UE functional recovery.
Methods:
Patients who underwent oncologic followed by reconstructive surgery by a single surgeon from 2014 to 2019 and completed the DASH survey were included. A DASH score was calculated for each patient, with values ranging from 0 (no impairment) to 100 (severe impairment). Regression analysis was conducted to identify significant predictors for DASH score with a significance level for entry and stay set at P = .15.
Results:
Among 289 patients who underwent breast reconstruction, 157 completed the questionnaire. The average patient age was 52.6yrs ± 8.6 at the time of reconstruction. A total of 111 had implant-based reconstruction, 15 had autologous reconstruction, and 24 had a combination of both. Average DASH score was 7.7 (range 0.0-52.5), with 74.1% of patients having a score greater than 0. Regression analysis showed 5 variables associated with significantly higher DASH scores: age between 50 and 60 years (P = .13), history of radiation (P = .01), placement of a subpectoral implant (P = .06), postoperative complications (P = .10), and lymphedema (P < .01). Autologous breast reconstruction (P = .04) was associated with a significantly lower DASH score.
Conclusions:
Implant-based reconstruction, radiation history, postoperative complications, and age at reconstruction were associated with increased UE functional impairment in patients who underwent breast reconstructive surgery. Identification of these factors can inform areas for potential practice changes and improve patient counseling regarding postoperative expectations.
