Intraoperative Radiation Therapy: A Large Integrated Health Care System's Approach and Outcomes.

Introduction Intraoperative radiation therapy (IORT) may not be as effective in the community compared with clinical trials. Methods The authors reviewed data from the electronic health records of patients who received IORT between February 2014 and February 2020 at a single center within a large integrated health care system. The primary outcome was ipsilateral breast tumor recurrence. Results Of 5731 potentially eligible patients, 245 (4.3%) underwent IORT (mean age: 65.4 ± 0.4 years; median follow-up time: 3.5 years ± 2.2 months). According to the American Society for Radiation Oncology's accelerated partial breast irradiation guidelines based on final pathology, 51% of patients were suitable candidates for IORT, 38.4% were cautionary, and 10.6% were unsuitable. For adjuvant therapy, 6.5% had consolidative whole breast irradiation, and 66.4% received endocrine treatment. At the median follow-up time of 3.5 years, overall ipsilateral breast tumor recurrence was 3.7%. Recurrences tended to be more frequent in patients who refused or did not complete endocrine treatment than in those who received it (7.4% vs 1.9%, p = 0.07). The complication rate was 14.7%, with seroma being the most common (8.2%). Discussion The IORT ipsilateral breast tumor recurrence rate of 3.7% confirms a higher-than-expected rate compared to randomized clinical trials, possibly due to less compliance with endocrine therapy. Conclusion The authors subsequently revised their IORT protocol to require endocrine treatment as a part of the IORT treatment plan and to strongly recommend adjuvant whole breast irradiation for all patients deemed cautionary or unsuitable for IORT according to the American Society for Radiation Oncology's accelerated partial breast irradiation guidelines.

Successful Design and Implementation of a POEM Program for Achalasia in an Integrated Healthcare System.

BACKGROUND: Per Oral Endoscopic Myotomy (POEM) is a minimally invasive treatment for achalasia with results comparable to laparoscopic Heller myotomy (LHM). Studies have described the development of proficiency for endoscopists learning to perform POEM, and societies have defined educational and technical objectives for advanced endoscopy fellows in training. However, there is limited guidance on the organizational strategy and educational plan necessary to develop an achalasia service with POEM expertise. AIMS: We aim to outline the steps for design and implementation of a successful POEM program. METHODS: We reported our experience developing a multi-disciplinary clinical program for POEM and the steps taken to achieve procedural proficiency. We also reported our technical success (successful tunneling into the gastric cardia and myotomy of LES muscle fibers) and clinical success (post-procedure Eckardt score ≤ 3) at 3-6 months and 12 months post-procedure. Adverse events were classified per the ASGE lexicon for endoscopic adverse events. RESULTS: After creating a multi-disciplinary clinical program for achalasia and completing procedural proficiency for POEM, our technical success rate was 100% and clinical success rate 90% for the first 41 patients. One adverse event (2.4%) occurred, moderate in severity per the American Society of Gastrointestinal Endoscopy (ASGE) lexicon for adverse endoscopic events. CONCLUSION: In this study, we outlined the steps involved to establish a POEM service in a large integrated healthcare system. Prior competency in interventional endoscopy, procedural training models, POEM observation and education, proctorship, and interdisciplinary patient care are recommended.

Same-Day Home Recovery for Benign Foregut Surgery.

Importance: Same-day home recovery (SHR) is now the standard of care for many major surgical procedures and has the potential to become standard practice for benign foregut procedures (eg, hiatal hernia repair, fundoplication, and Heller myotomy). Objective: To determine whether SHR for patients undergoing benign foregut surgery is feasible, safe, and effective. Design, Setting, and Participants: This prospective cohort study took place across 19 medical centers within an integrated health care system in northern California from January 2019 through September 2021. Participants included consecutive patients undergoing elective benign foregut surgery. Exposures: Standardized SHR program. Main Outcomes and Measures: The primary end point was the rate of SHR. The secondary end points were 7-day and 30-day rates of postoperative emergency department visits, hospital readmissions, and reoperations. Results: Of 1248 patients who underwent benign foregut surgery from January 2017 through September 2021, 558 were patients before implementation of the SHR program and 690 were patients postimplementation. The mean age of patients was 60 years, and 759 (59%) were female. The preimplementation SHR rate was 64 of 558 patients (11.5%) in 2018 and increased to 82 of 113 patients (72.6%) by 2021 (94/350 [26.9%] in 2019 and 112/227 [49.3%] in 2020; P < .001). There were no statistical differences in the 7-day and 30-day rates of postoperative emergency visits, hospital readmissions, and reoperations or 30-day mortality in the SHR vs non-SHR groups in the postimplementation era. Conclusions and Relevance: In this study, implementation of a regional SHR program among patients undergoing elective benign foregut surgery was feasible, safe, and effective. The changes in perioperative care require comprehensive patient education and full multidisciplinary support. An SHR program for benign foregut procedures has the potential to improve patient care and cost-effectiveness in care delivery.

Patients Older 65 Years With Early Breast Cancer Prefer Intraoperative Radiation as a Locoregional Treatment Choice.

BACKGROUND: Patients 65 years old or older with early endocrine-responsive breast cancer have many treatment options, including no radiation. This study aimed to evaluate treatment preference when intraoperative radiation therapy (IORT) is offered in this population. METHODS: The study reviewed patients 65 years old or older with a diagnosis of early-stage endocrine-responsive breast cancer in 2016-2019 at a single hospital in a large integrated health care system. Electronic medical records of multidisciplinary breast tumor board discussion, treatment options documented by the treatment team, and final treatment offered were reviewed. Variables including age at biopsy, language, endocrine treatment, and comorbidities were collected. Regression analysis was used to evaluate for variables associated with patients' choice regarding radiation treatment. RESULTS: The institutional IORT guidelines were met by 63 patients in the described age group who had a documented offer of all radiation treatment options. The median age of the patients was 70 years (interquartile range 63-77 years). Overall, 74.6% of the patients chose IORT, and 14.3% opted for whole-breast irradiation. Only 4.8% chose to omit radiation after breast-conserving surgery, and 6.3% chose mastectomy. The patients who chose IORT were more likely to receive endocrine treatment (odds ratio 3.70; p = 0.03). Age, race, language, and comorbidities were not associated with preference for IORT (p < 0.05). CONCLUSIONS: Patients 65 years old or older with early-stage endocrine-responsive breast cancer preferred to have IORT despite counsel about the lack of survival benefit. This study suggests that local cancer control with the convenient radiation delivery method is important to the described patient population.
