1101 Background: A recent randomized trial (MA.20) showed that regional nodal irradiation (RNI) in addition to breast irradiation in high risk node negative and 1-3 node positive patients undergoing breast-conserving therapy (BCT) reduced the risk of recurrence and improved disease-free survival. We investigated the trends of RNI use in the United States and related factors for the use of RNI using the National Cancer Data Base. Methods: This study includes 292,598 stage I-III breast cancer patients without neoadjuvant therapy who underwent BCT from 2003-2007. We investigated pathological, patient, and facility factors related to RNI use, by multivariable logistic regression, with odds ratio (OR) estimations. Results: The proportion of radiotherapy use after BCT slightly declined from 78.6% in 2003 to 75.6% in 2007. The use of breast irradiation plus RNI decreased from 10.8% in 2003 to 8.3% in 2007 (p<0.0001). The number of tumor positive lymph nodes strongly determined the use of additional RNI: 4.4% patients with negative nodes, 22.8% patients with 1-3 nodes, and 39.7% patients with 4 or more nodes received breast irradiation plus RNI after undergoing BCT (p<0.0001). The proportion of patients undergoing RNI significantly decreased over the study period from 43.3% to 37.2% in the 4+ node positive group, and from 23.6% to 22.0% in the 1-3 node positive group. At comprehensive community cancer centers, 25.5% patients with 1-3 positive nodes were treated with breast irradiation plus RNI (vs. 23.2% in community cancer centers and 21.1% in academic/research cancer centers). Among node negative patients, 11.5% of those with tumor size greater than 5 cm received additional RNI, compared to 4.3% in patients with tumors less than 5cm (p<0.0001). Other significant factors related to RNI use included higher tumor grade, younger age, facility location, and facility volume. Conclusions: The use of RNI varies by number of tumor positive nodes and facility factors. Only 22.8% of patients with 1-3 positive nodes underwent RNI. Future studies are needed to determine if the use of RNI will increase after publication of the MA.20 trial especially for the 1-3 node positive group.

391 Background: There are no randomized data to guide clinicians treating patients with gallbladder cancer (GBC). Several retrospective studies reported the survival benefits of adjuvant radiotherapy (RT) and chemoradiation (CRT). The aims of this study were to examine whether these publications have impacted the utilization of adjuvant therapies and whether their survival benefits were evident in contemporary cohort of patients. Methods: Using the National Cancer Data Base, we identified 5,029 patients diagnosed with T1-3N0-1 GBC and treated with surgical resection from 2005 to 2013. We described trends in receipt of adjuvant treatments for three time periods (2005-2007, 2008-2010, 2011-2013) and calculated 3-year overall survival (OS) probabilities for 2,989 patients treated in 2005-2010. Results: The percentage of patients who received no adjuvant treatment was unchanged from 2005 to 2013. Adjuvant RT decreased from 4.3% to 1.7% (p < 0.01), adjuvant chemotherapy increased from 8% to 14% (p < 0.01), and adjuvant CRT remained stable at 16% (p = 0.98). Even for locally advanced disease (T3N0 and T1-3N1) or in the setting of positive resection margins, over 50% of patients in US did not receive adjuvant treatments. Adjuvant treatments were associated with improved 3-year overall survival in patients with resected GBC, as listed in Table. Adjuvant CRT was associated with improved survival in all stages, except T1N0, and in patients with negative and positive margins. Conclusions: Over the past decade there was no increase in the utilization of adjuvant therapies in the US for patients with resected GBC. Adjuvant therapy is associated with significantly improved 3-yr OS. In the absence of randomized data, this analysis should form the basis for clinical recommendations and national guidelines should be amended to support adjuvant treatment.[Table: see text]
