328 Background: Stereotactic Body Radiation Therapy (SBRT) is emerging as a possible standard treatment for pancreatic cancer; however, there is limited data to support its efficacy. This study reviews our institution’s experience using SBRT in the treatment of pancreatic cancer (PCA). Methods: Charts of all PCA patients receiving SBRT from January 2010 to June 2013 were retrospectively reviewed. The primary end points were overall survival (OS) and tumor response assessed by RECIST criteria. 95% of the PTV (GTV + 2-3 mm) received a total dose of 20-33 Gy in five fractions (4-6.6 Gy/fraction), with up to 20% heterogeneity allowed. Pre- and post-SBRT chemotherapy regimens included gemcitabine, cisplatin, FOLFIRINOX, 5-FU or paclitaxel. Results: 84 patients received SBRT, with a median follow-up time of 15.3 months. Median age was 66.5 years, 57.1% were male and 65.5% had head tumors. 66 patients received definitive SBRT for locally advanced or borderline resectable PCA, 4 patients were treated with adjuvant SBRT, and 14 received SBRT for treatment of recurrent disease. Median OS from the date of diagnosis for patients receiving definitive radiation was 17.8 mos (95% CI 14.9-20.9).For recurrent patients the median OS from first day of SBRT was 11.8 mos (95%CI 8.3-15.3). In the definitive SBRT group, among patients who were alive and had follow-up scans, the 6 and 12 month local control rate (stable or partial response) based on RECIST criteria was 84.6% and 81.8%, respectively. Five patients underwent surgery following SBRT and all had negative resection margins. Acute toxicity was minimal with most experiencing grade 1 or 2 fatigue and no grade 3/4 acute toxicity. Late grade 3/4 GI toxicity was seen in 5% (4/84) and 1 patient had a grade 5 GI bleed due to direct tumor invasion into the duodenum. Conclusions: Our early results using SBRT in the definitive and recurrent settings show favorable local control, toxicity, and survival when compared to historical outcomes using chemoradiation. Acute and late toxicity was minimal however the optimal dose and fractionation as well as normal tissue dose constraints need to be determined. Integration of SBRT with more aggressive chemotherapy may result in improved outcomes in patients with PCA.

335 Background: Unresectable intrahepatic cholangiocarcinoma has a poor prognosis with less than 5% of patients surviving 5 years. We review our experience with stereotactic body radiation therapy (SBRT) in the treatment of unresectable intrahepatic cholangiocarcinoma and evaluate acute toxicity and local control. Methods: From November 2005 until August 2010, 12 patients with unresectable intrahepatic cholangiocarcinoma were treated with SBRT. All patients were evaluated by a liver surgeon and were deemed unresectable prior to radiosurgery. The median tumor size was 4.3 cm (range 1.9–9.3 cm). All tumors were located in the right hepatic lobe. Three patients had received prior radiation therapy and SBRT was given as a boost with a median dose of 24 Gy in three fractions. Nine patients received SBRT as the sole local modality to a median dose of 51 Gy (range 30–55 Gy) in three fractions on consecutive days. Local control was determined by follow-up imaging with MRI. The median follow up is 12 months. Toxicity was assessed using Common Toxicity Criteria (CTC) guidelines version 3.0. Results: Overall, only 3 of 12 (25%) patients experienced acute toxicity. Three patients had abdominal discomfort and one patient had nausea. All toxicities were grade 1. Ten of 12 (83%) patients received chemotherapy. Four patients received chemotherapy before SBRT and five patients received chemotherapy after. One patient received chemotherapy before and after SBRT. Overall local control is 75% for eight patients with follow-up imaging. Two of eight (25%) patients had a complete response. Four of eight (67%) patients had a partial response or stable disease. One patient had a local recurrence 13 months after receiving SBRT (51 Gy in three fractions) and was retreated with SBRT (28 Gy in three fractions) with no acute toxicity. There was no difference in outcome whether SBRT was given before or after chemotherapy. Conclusions: Stereotactic body radiation therapy given sequentially with chemotherapy is well tolerated with few side effects in the treatment of unresectable intrahepatic cholangiocarcinoma and early local control is promising. No significant financial relationships to disclose.

84 Background: Prospective evaluation of correlations between patient- (PROs) and physician-reported outcomes (PhROs) was conducted among a group of patients receiving stereotactic body radiation therapy (SBRT) for recurrent or locally advanced pancreatic cancer (PCA). Methods: Forty-two patients were treated with 25-33 Gy using SBRT in 5 fractions on a single-institution study. Eight outcomes (performance status, fatigue, pain, anorexia, nausea, vomiting, constipation, and diarrhea) were consistently evaluated by patients and providers prior to SBRT and 4-6 weeks post-SBRT. Patient-reported quality of life (QOL) metrics were assessed using the EORTC QLQ-C30 and QLQ-PAN26, while physician-reported toxicities were graded using the NCI CTCAE v4.0.A Pearson’s correlation was used to determine the relationship between PROs and PhROs. Results: Of the 42 enrolled patients, 36 had both PROs and PhROs collected before (median, 2.9 weeks) SBRT. Physician-reported pain, nausea, constipation, and diarrhea did not show a correlation with patient-reported overall health or QOL. Physician-reported fatigue showed a correlation with patient-reported pain (r > 0.5, p < 0.001) and QOL (r > -0.5, p < 0.001) but not fatigue (r < 0.3, p > 0.05). Nausea and constipation were the only PROs that did not correlate with their respective PhROs (nausea, r < 0.3, p > 0.05; constipation, r < 0.5, p = 0.07) or any of the other 7 PhROs. Only 24 had both PROs and PhROs collected 4-6 weeks after (median, 5.1 weeks) SBRT. Vomiting, constipation, and diarrhea were PhROs that demonstrated no correlation with patient-reported overall health or QOL. Physician-reported vomiting did not correlate with patient-reported vomiting (r < 0.3, p > 0.05) or any of the 7 other PROs. The correlation between patient- and physician-reported pain increased from pre- (r > 0.3, p = 0.03) to post- (r > 0.7, p < 0.0001) SBRT. Conclusions: Discrepancies among PROs and PhROs appear to exist in pancreatic-specific outcomes of interest such as constipation and diarrhea. Future health care teams may find it helpful to consider PROs to better manage symptoms and deliver more personalized care. Clinical trial information: NCT01781728.

341 Background: The surgical outcome of patients with borderline resectable or locally advanced pancreatic ductal adenocarcinoma (BRPC/LAPC) treated with stereotactic body radiation therapy (SBRT) is unclear. Methods: A comparative study was performed to determine if surgical outcomes were different among patients receiving neoadjuvant SBRT vs chemoradiation therapy (CRT) vs chemotherapy only. Results: Between 2011 and 2014, 29 patients with BR/LA-PDAC underwent neoadjuvant chemotherapy and SBRT (6.6 Gy x 5 fractions) followed by pancreatectomy. Eighteen of 29 patients (62%) had LAPC. Their outcomes were compared with 82 patients who received neoadjuvant CRT and 26 patients who received neoadjuvant chemotherapy only (Table). When compared to neoadjuvant CRT and chemo only, the neoadjuvant SBRT group had a higher R0 resection rate (90% vs 84% vs 62%, p=0.02) and vascular resection rate (41% vs 13% vs 31%, p=0.005), respectively. Although the vascular resection and complication rates (Clavien grade 3 or above) were higher in the neoadjuvant SBRT group, no in-hospital mortality was encountered. In the SBRT group, the complete pathological response rate (21%) was higher than that of the other groups (4% and 0% respectively, p<0.001). Survival will be updated later as the current median postoperative follow-up is 6 months in the SBRT group. Conclusions: Neoadjuvant chemotherapy and SBRT is associated with improved surgical outcomes and pathologic complete response rates in selected patients with BRPC/LAPC. Longer follow-up is needed to determine its impact on survival. [Table: see text]
