    Abstract: Shorter fractionation radiation regimens for palliation of bone metastases result in lower financial and social costs for patients and their caregivers and have similar efficacy as longer fractionation schedules, although practice patterns in the United States show poor adoption. We investigated whether prospective peer review can increase use of shorter fractionation schedules. Methods: In June 2016, our practice mandated peer review of total dose and fractionation for all patients receiving palliative treatment during our weekly chart rounds. We used descriptive statistics and Fisher’s exact test to compare lengths of treatment of uncomplicated bone metastases before and after implementation of the peer review process. Results: Between July 2015 and December 2016, a total of 242 palliative treatment courses were delivered, including 105 courses before the peer review intervention and 137 after the intervention. We observed greater adoption of shorter fractionation regimens after the intervention. The use of 8 Gy in one fraction increased from 2.8% to 13.9% of cases postadoption. Likewise, the use of 20 Gy in five fractions increased from 25.7% to 32.8%. The use of 30 Gy in 10 fractions decreased from 55.2% to 47.4% ( P = .002), and the use of ≥ 11 fractions decreased from 16.2% before the intervention to 5.8% after ( P = .006). Conclusion: Prospective peer review of palliative regimens for bone metastases can lead to greater adoption of shorter palliative fractionation schedules in daily practice, in accordance with national guidelines. This simple intervention may therefore benefit patients and their caregivers as well as provide value to the health care system.

    Assessing the clinical significance of real-time quality of life data in cancer patients treated with radiation therapy.
    American Society of Clinical Oncology (ASCO) ; 2012

    Abstract: 6108 Background: This pilot study evaluated whether providing clinicians with patient(pt) QOL results and symptom management pathways linked to QOL domains at the time of clinical appointment would result in improvement in QOL and treatment (tx) satisfaction. The objective was to obtain preliminary effect size estimates and logistical evidence for design of a larger, definitive trial. Methods: Oncology pts receiving 5-7 weeks of radiotherapy (RT) electronically completed QOL assessments (LASA) at baseline and biweekly prior to seeing clinicians. Was It Worth It (WIWI) and Interpersonal Patient-Provider Relationship (IPPRS) were measured at tx end. Pt endpoints (pro-rated primary endpoint LASA area under the curve (AUC), LASA changes from baseline, and WIWI responses) and clinician endpoints (IPPRS) were compared between the control group (Phase 1: no QOL feedback) and the intervention group (Phase 2: QOL feedback) via Wilcoxon, Chi-square and Fisher Exact tests. There was 80% power to detect a 10 point difference in average AUC. Results: 148 pts enrolled (79 Phase 1, 69 Phase 2) from 11/28/2008 to 09/20/2011 (sites GI (27%), Lung (22%) and Head and Neck (52%)). 68% received RT and chemo. There were consistently moderate effect sizes observed but no statistically significant differences in any AUC nor end of tx change from baseline scores. 20% fewer pts in phase 2 reported clinical deficits in overall QOL (pain). In pts receiving 7 weeks of RT, end of tx average overall QOL, mental well-being (WB), physical WB and pain severity were significantly better in Phase 2 pts. WIWI results showed 76% found participation worthwhile, 95% would participate again, and 92% would recommend the study to others. No differences between groups were found in communication between clinicians and pts (IPPRS). Conclusions: Preliminary estimates indicate potentially clinically significant improvements of moderate effect size in mental and physical WB and pain severity when clinicians received QOL real time with symptom management pathways. Further study is warranted in larger trial setting.

    Abstract: 327 Background: The use of preoperative therapy for pancreatic cancer remains controversial. This study reviews our experience using neoadjuvant chemotherapy and chemoradiation (CRT) followed by surgery with intraoperative electron irradiation (IOERT) for patients with borderline resectable (BR) or unresectable (UR) tumors. Methods: A retrospective review identified 48 patients (pts) with primary BR/UR pancreas adenocarcinoma treated with preop CRT with intent to proceed to curative surgery with IOERT. Seventeen patients did not undergo attempted resection and are excluded (disease progression, 12; medically inoperable, 3; declined surgery, 2). Thirty-one patients proceeded to resection attempt and are the subject of this analysis. Kaplan-Meier survival analysis was performed using log rank test for significance. Median follow up was 19 months (mo). Results: Complete resection (R0) was achieved in 11 pts, R1 in 5, and R2 or not resected (IOERT alone) in 15 patients. Twenty-six pts died (23 of disease, 2 unrelated causes, 1 uncertain). Median overall survival (OS) was 19 mo for all pts. Local progression was detected in only 5 patients (16%) while distant disease developed in 24 (77%). Resection status significantly correlated with OS; R0/R1 patients had a median survival of 23 mo vs. 10 mo for R2/unresected tumors (p = 0.002). Three-year OS was 35% vs. 0%, respectively. Survival was not influenced by tumor location, CA19-9 baseline or response, tumor size, or initial judgment of resectability (BR vs. UR). BR tumors were resectable after neoadjuvant therapy in 9 of 11 patients (R0, 8; R1, 1) while 8 of 20 initially UR tumors underwent resection (R0, 3; R1, 4; R2, 1). Conclusions: Neoadjuvant therapy combined with IOERT has the possibility to improve patient selection for surgical resection and to optimize local therapy. Although the prognosis for locally advanced pancreatic cancer remains poor, survival was superior among patients for whom R0 or R1 resection was achieved. Distant metastasis remained the dominant pattern of failure, and novel systemic agents are needed. Prospective evaluation of the impact of neoadjuvant chemotherapy, CRT, and IOERT is warranted.
