Abstract Background Adult intracranial ependymoma is rare, and the role for adjuvant radiotherapy (RT) is not well defined. Methods We used the National Cancer Database (NCDB) to select adults (age ≥ 22 years) with grade 2 to 3 intracranial ependymoma status postresection between 2004 and 2015 and treated with adjuvant RT vs observation. Four cohorts were generated: (1) all patients, (2) grade 2 only, (3) grade 2 status post–subtotal resection only, (4) and grade 3 only. The association between adjuvant RT use and overall survival (OS) was assessed using multivariate Cox and propensity score matched analyses. Results A total of 1787 patients were included in cohort 1, of which 856 patients (48%) received adjuvant RT and 931 (52%) were observed. Approximately two-thirds of tumors were supratentorial and 80% were grade 2. Cohorts 2, 3, and 4 included 1471, 345, and 316 patients, respectively. There was no significant association between adjuvant RT use and OS in multivariate or propensity score matched analysis in any of the cohorts. Older age, male sex, urban location, higher comorbidity score, earlier year of diagnosis, and grade 3 were associated with increased risk of death. Conclusions This large NCDB study did not demonstrate a significant association between adjuvant RT use and OS for adults with intracranial ependymoma, including for patients with grade 2 ependymoma status post–subtotal resection. The conflicting results regarding the efficacy of adjuvant RT in this patient population highlight the need for high-quality studies to guide therapy recommendations in adult ependymoma.

Objective Epiaortic ultrasound (EU) reliably reveals ascending aortic atherosclerosis (AAA), allowing strategies to minimize the risk of embolization or plaque disruption during coronary artery bypass grafting. Our objective was to delineate if EU-guided intervention improved outcomes. Methods Patients undergoing coronary artery bypass grafting (2004–2007) were categorized by EU grade (grade 1–2 [mild] vs. 3–5 [moderate/severe]) and the use of an aortic clamp. A propensity score estimated probability of clamp use was based on 45 risk factors. Multiple logistic regression models measured the association between outcomes—death, stroke, myocardial infarction, and major adverse cardiac and cerebrovascular events (MACCE)—and the primary variables (grade and clamp use), adjusted for propensity score. Results Grade was available in 4278 patients. Patients with grade 3 to 5 AAA had an increased risk of death (adjusted odds ratios (AOR) 3.11; P < 0.001), stroke (AOR 2.12; P < 0.001), and MACCE (AOR 2.58; P < 0.001). Aortic clamping (any clamp, all grades) led to a higher risk of stroke (AOR 2.77; P = 0.032). EU altered aortic manipulation in 530 patients (12.4%). In this group, patients with high grade aortas had similar rates of death, stroke or MACCE, when compared with patients with low-grade aortas. Conclusions EU alters surgical strategy. Patients with grade 3 to 5 AAA are at increased risk of death, stroke, and MACCE compared with patients with grade 1 to 2 AAA. Clamping the aorta (any grade) increases the risk for stroke. Aortic clamping should be avoided in patients with grade 3 to 5 AAA, but EU may minimize morbidity and mortality if a clamp must be used.

OBJECTIVEChordomas of the spine and sacrum are a rare but debilitating cancer and require complex multidisciplinary care. Studies of other such rare cancers have demonstrated an association of high-volume and/or multidisciplinary centers with improved outcomes and survival. Such an association has been proposed for chordomas, but evidence to support this claim is lacking. The authors performed a study to investigate if treatment facility type is associated with patterns of care and survival for patients with spinal and sacral chordomas by assessing records from a US-based cancer database.METHODSIn this observational retrospective cohort study, the authors identified 1266 patients from the National Cancer Database with vertebral column or sacral chordomas diagnosed between 2004 and 2015. The primary study outcome was overall survival, and secondary outcomes included odds of receiving treatment and time to treatment, defined as radiation therapy, surgery, and/or any treatment, including surgery, radiation therapy, chemotherapy, or participation in clinical trials. The results were adjusted for age, sex, race/ethnicity, level of education, income, and Charlson/Deyo score.RESULTSOf the 1266 patients identified, the mean age at diagnosis was 59.70 years (SD 16.2 years), and the patients were predominantly male (n = 791 [62.50%]). Patients treated at community cancer programs demonstrated an increased risk of death (HR 1.98, 95% CI 1.13–3.47, p = 0.018) when compared to patients treated at academic/research programs (ARPs). The median survival was longest for those treated at ARPs (131.45 months) compared to community cancer programs (79.34 months, 95% CI 48.99–123.17) and comprehensive community cancer programs (CCCPs) (109.34 months, 95% CI 84.76–131.45); 5-year survival rates were 76.08%, 52.71%, and 61.57%, respectively. Patients treated at community cancer programs and CCCPs were less likely to receive any treatment compared to those treated at ARPs (OR 6.05, 95% CI 2.62–13.95, p < 0.0001; OR 3.74, 95% CI 2.23–6.28, p < 0.0001, respectively). Patients treated at CCCPs and community cancer programs were less likely to receive surgery than those treated at ARPs (OR 2.69, 95% CI 1.82–3.97, p = 0.010; OR = 2.64, 95% CI 1.22–5.71, p = 0.014, respectively). Patients were more likely to receive any treatment (OR 0.59, 95% CI 0.40–0.87, p = 0.007) and surgery (OR 0.58, 95% CI 0.38–0.88, p < 0.0001) within 30 days at a CCCP compared to an ARP. There were no differences in odds of receiving radiation therapy or time to radiation by facility type.CONCLUSIONSClinical care at an ARP is associated with increased odds of receiving treatment that is associated with improved overall survival for patients with spinal and sacral chordomas, suggesting that ARPs provide the most comprehensive specialized care for patients with this rare and devastating oncological disease.

5059 Background: Stereotactic body radiotherapy (SBRT) is being increasingly used for renal cell carcinoma (RCC) treatment in non-surgical candidates. However, no studies have compared survival between nephrectomy and SBRT. The National Cancer Database (NCDB) database was used to assess overall survival in patients undergoing SBRT vs nephrectomy. Methods: All cases of T1-T4, N0, M0 RCC diagnosed between 2004 and 2016 were extracted from the NCDB. Only patients undergoing either nephrectomy or SBRT, but not both, were included in the final analysis. Primary outcome was overall survival, defined as time in months from diagnosis to death due to any cause. Descriptive statistics were calculated for all variables. Univariate survival analysis was performed using the Kaplan Meier method and log rank test. Multivariate Cox proportional hazards regression models were performed to determine the predictive performance of covariates with respect to overall survival, reported as hazard ratio [HR] with 95% CIs. Nephrectomy patients were propensity score matched to SBRT patients for sub-cohort survival analysis. Comparisons were considered statistically significant at P < 0.05. Results: There were 243,754 patients meeting inclusion criteria with 243,488 undergoing nephrectomy and 266 undergoing SBRT. Five year OS rates were 53% and 80% for SBRT and nephrectomy, respectively (P < 0.001). On multivariate Cox regression, SBRT was associated with an increased risk of death as compared to nephrectomy (HR, 2.05; 95% CI, 1.72 – 2.44; P < 0.001). Sex, race, insurance coverage, comorbidity index, tumor grade, lymphovascular invasion status, T-stage, tumor size, and academic status of treatment facility were also independent predictors of survival. After propensity score matching of 266 SBRT patients to 266 nephrectomy patients, there were no significant differences in baseline characteristics between the groups. However, SBRT continued to demonstrate worse survival and an increased risk of death as compared to nephrectomy (HR, 1.85; 95% CI, 1.41 – 2.44; P < 0.001). Conclusions: Among node-negative, non-metastatic RCC patients, SBRT is associated with inferior survival outcomes as compared to nephrectomy, even after correcting for underlying differences in demographics, tumor characteristics, socioeconomic status, and comorbidities. These results indicate that nephrectomy should remain the standard of care for RCC patients, with SBRT reserved for non-surgical candidates.

OBJECTIVEAnaplastic meningiomas represent 1%–2% of meningioma diagnoses and portend a poor prognosis. Limited information is available on practice patterns and optimal management. The purpose of this study was to define treatment patterns and outcomes by treatment modality using a large national cancer registry.METHODSThe National Cancer Database was used to identify patients diagnosed with anaplastic meningioma from 2004 to 2012. Log-rank statistics were used to compare survival outcomes by extent of resection, use of adjuvant radiotherapy (RT), and use of adjuvant chemotherapy. Least-squares linear regression was used to evaluate the utilization of RT over time. Logistic regression modeling was used to identify predictors of receipt of RT. Cox proportional hazards modeling was used to evaluate the effect of RT, gross-total resection (GTR), and chemotherapy on survival.RESULTSA total of 755 adults with anaplastic meningioma were identified. The 5-year overall survival rate was 41.4%. Fifty-two percent of patients received RT, 7% received chemotherapy, and 58% underwent GTR. Older patients were less likely to receive RT (OR 0.98, p < 0.01). Older age (HR 1.04, p < 0.01), high comorbidity score (HR 1.33, p = 0.02), and subtotal resection (HR 1.57, p = 0.02) were associated with increased risk of death on multivariate modeling, while RT receipt was associated with decreased risk of death (HR 0.79, p = 0.04). Chemotherapy did not have a demonstrable effect on survival (HR 1.33, p = 0.18).CONCLUSIONSAnaplastic meningioma portends a poor prognosis. Gross-total resection and RT are associated with improved survival, but utilization of RT is low. Unless medically contraindicated, patients with anaplastic meningioma should be offered RT.

Abstract In the 2016 WHO classification of CNS tumors, oligodendrogliomas are molecularly defined by IDH1 or IDH2 mutations and 1p/19q co-deletion. Some reports suggest that PI3K pathway alterations may confer increased risk of progression and poor prognosis in oligodendroglioma. However, factors that influence prognosis in molecularly defined oligodendroglioma (mOGD) have not been thoroughly studied. Also, the benefits of adjuvant radiation and temozolomide in mOGDs remain to be determined. 107 mOGDs diagnosed between 2008-2018 at the University of Texas Health Science Center at Houston (n= 39) and MD Anderson Cancer Center (n= 68) were included. A retrospective review of the demographic, clinical, histologic, molecular, and outcomes were performed. Median age at diagnosis was 37 years and 61 (57%) patients were male. There were 64 (60%) WHO Grade 2 and 43 (40%) WHO Grade 3 tumors. Ninety-five (88.8%) tumors were IDH1-mutant and 12 (11.2%) were IDH2-mutant. Eighty-two (77%) patients were stratified as high-risk: older than 40-years and/or subtotal resection (RTOG 9802). Gross-total resection was achieved in 47 (45%) patients. Treatment strategies included observation (n= 15), temozolomide (n= 11), radiation (n= 13), radiation with temozolomide (n= 62) and other (n= 6). Our results show a benefit of temozolomide vs. observation in progression-free survival (PFS). However, no benefit in PFS or overall survival (OS) was observed when comparing radiation vs. radiation with temozolomide. PIK3CA mutations were detected in 15 (14%) cases, and patients with PIK3CA-mutant mOGDs showed worse OS (10.7-years vs 15.1-years, p= 0.009). Patients with WHO Grade 3 tumors had shorter PFS but no significant difference in OS was observed compared to grade 2. Our findings suggest that mOGDs harboring PIK3CA mutations have worse OS. Except for an advantage in PFS in temozolomide treated patients, adjuvant treatment with radiation or the combination of both, showed no significant advantage in terms of OS.

Abstract BACKGROUND Pilocytic astrocytoma (PCA) is a low-grade glioma common in children but also rarely diagnosed in adults. The role of adjuvant radiation therapy (RT) in treating these tumors remains unclear. OBJECTIVE We investigated the effect of RT on overall survival, specifically among adult patients who had undergone subtotal PCA resection. METHODS Information on adult patients (age 18 years old) who had undergone subtotal PCA resection between 2004 and 2016 was collected from the National Cancer Database (NCDB). A multivariate Cox proportional hazards model was utilized to determine factors independently associated with overall survival. RESULTS A total of 451 patients were identified. The mean age of our patient cohort was 36.8 years old, and the majority of patients (83.4%) did not receive radiation treatment following subtotal PCA resection. Overall median survival was 93.8 months. Survival was longer (p &lt; 0.001) in the patients who did not receive post-surgical RT (median: 98.3 months) compared to patients who did (median: 54.8 months). Patients who had older age at diagnosis (hazard ratio [HR]=1.05, 95% confidence interval [CI]=1.03-1.07, p &lt; 0.01), were Black or African American (HR=2.76, CI=1.12-6.46, p=0.019), received radiation during their initial treatment (HR=4.53, CI=2.08-9.89, p &lt; 0.01), or had a Charlson/Deyo score of &gt; 1 (HR=3.68, CI=1.55, p=0.003) had a significantly higher risk of death following subtotal PCA resection. CONCLUSION Postoperative RT is independently associated with a significantly higher risk of death among adults who underwent subtotal PCA resection. Our findings provide a rationale for further investigation into the efficacy and safety of RT within this patient population.

Prospective studies have shown equal outcomes after mastectomy or breast conservation in patients with invasive breast cancer; however, many of these studies excluded elderly patients. We identified patients in their eighties and nineties with clinical stage 0 to II breast cancer undergoing mastectomy or lumpectomy with or without radiation from the prospective sentinel lymph node database at Wake Forest Baptist Health and analyzed their treatment and survival. Of 92 patients, 24 (26.1%) underwent mastectomy, 22 (23.9%) lumpectomy with radiation, and 46 (50.0%) lumpectomy alone. Significant differences were noted in tumor size (P = 0.018), nodal status (P = 0.013), and stage (P = 0.011) between the groups. Only 7.6 per cent of patients had chemotherapy, whereas 51.1 per cent took antiestrogen therapy. Recurrence occurred in 11 patients. In univariate analysis, overall survival did not differ by surgery. Age was the only factor that increased risk of death (HR = 1.19, P = 0.028). In this age group, neither tumor factors nor the type of local treatment significantly influenced overall survival. Octogenarians and nonagenarians with early-stage breast cancer undergoing breast-conserving surgery with or without radiation have equivalent survival to patients having a mastectomy.

Background. Leiomyosarcomas (LMS) represent a heterogeneous subset of soft tissue sarcomas. Factors influencing prognosis for patients with metastatic extrauterine LMS (euLMS) are not well described. Limited data are available regarding responses to systemic therapy.Methods. We collected clinical and pathologic information for all patients with metastatic euLMS seen at Memorial Sloan Kettering Cancer Center between 1989 and 2012. Objective responses to first-line therapy were analyzed for a subset of patients with available baseline and on-treatment imaging using RECIST 1.1.Results. 215 patients with metastatic euLMS had a median overall survival (OS) of 2.6 years from the time of metastasis. Older age, male sex, and ≥3 initial sites of metastasis were associated with worse OS on multivariate analysis. Objective response rate (ORR) inN=113was 19% overall and 25%, 26%, and 25% for gemcitabine, gemcitabine plus docetaxel, and anthracycline-alkylator combinations. Patients whose tumors objectively responded to first-line therapy had a lower risk of death versus those who did not (Hazard Ratio 0.46; 95% CI: 0.26–0.79,p=0.005).Conclusions. Anthracycline- and gemcitabine-based regimens have similar activity in this cohort of euLMS. Prognostic factors for OS include older age, male sex, and ≥3 initial sites.
