Using standardized workflows and quantitative data-driven management to reduce time interval from simulation to treatment initiation.

PURPOSE: External beam radiotherapy is a complex process, involving timely coordination among multiple teams. The aim of this study is to report our experience of establishing a standardized workflow and using quantitative data and metrics to manage the time-to-treatment initiation (TTI). METHODS AND MATERIALS: Starting in 2014, we established a standard process in a radiation oncology-specific electronic medical record system (RO-EMR) for patients receiving external beam radiation therapy in our department, aiming to measure the time interval from simulation to treatment initiation, defined as TTI, for radiation oncology. TTI data were stratified according to the following treatment techniques: three-dimensional (3D) conformal therapy, intensity-modulated radiotherapy (IMRT), and stereotactic body radiotherapy (SBRT). Statistical analysis was performed with the Mann-Whitney test for the respective metrics of aggregate data for the initial period 2012- 2015 (PI) and the later period 2016-2019 (PII). RESULT: Over 8 years, the average annual number of treatments for PI and PII were 1760 and 2357 respectively, with 3D, IMRT, and SBRT treatments accounting for 53, 29, 18% and 44, 34, 22%, respectively, of the treatment techniques. The median TTI for 3D, IMRT, and SBRT for PI and PII were 1, 6, 7, and 1, 5, 7 days, respectively, while the 90th percentile TTI for the three techniques in both periods were 5, 9, 11 and 4, 9, 10 days, respectively. From the aggregate data, the TTI was significantly reduced (p = 0.0004, p < 0.0001, p < 0.0001) from PI to PII for the three treatment techniques. CONCLUSION: Establishing a standardized workflow and frequently measuring TTI resulted in shortening the TTI during the early years (in PI) and maintaining the established TTI in the subsequent years (in PII).

Neoadjuvant Reirradiation for Radiation Therapy-Associated Angiosarcoma of the Breast.

PURPOSE: Radiation-associated angiosarcoma of the breast (RAASB) is a rare side effect after breast radiation and has been associated with poor outcomes. At this time, there is no consensus regarding management of RAASB, and the role of reirradiation remains controversial. We present our modern institutional outcomes in managing RAASB with incorporation of neoadjuvant hyperfractionated reirradiation. METHODS AND MATERIALS: Patients identified were treated between 2016 and 2020 with inclusion of any histologically proven RAASB without metastatic disease at diagnosis, while excluding those with a history of radiation therapy outside of the breast/chest wall or other sarcoma histologies. Major wound complications were defined as requiring wound care and/or wound vacuum or return to the operating room for wound repair at any time after surgery. RESULTS: Eight patients were identified, and the median follow-up was 34 months. Median time to RAASB development was 8 years from initial radiation therapy. With respect to RAASB management, all underwent surgery and neoadjuvant reirradiation therapy, and all but 1 patient received taxol-based chemotherapy. At last follow-up, 7 patients remained free of disease, and 1 patient died with distant disease. With respect to acute toxicity after reirradiation, all patients developed at least acute grade 2 toxicities. Five of the 8 patients developed a major wound complication. CONCLUSIONS: Our institutional analysis suggests excellent local control and survival outcomes for RAASB treated with neoadjuvant hyperfractionated reirradiation, surgery, and taxol-based chemotherapy. However, major wound complications represent a major challenge with this approach. Future studies should consider how best to improve the therapeutic ratio while maintaining high rates of local control and survival.
