    Abstract: 2518 Background: This study sought to evaluate the prognostic significance of the three WHO-defined molecular glioma subgroups ( IDHwt, IDHmt/non-codel, and IDHmt/codel) in NRG Oncology/RTOG 0424, a phase II trial of high-risk low-grade gliomas treated with radiation (RT) and concurrent and adjuvant temozolomide (TMZ) after biopsy/surgical resection. Notably, this is the first clinical study to evaluate the prognostic value of the WHO subgroups in RT + TMZ-treated high-risk grade II (G2) gliomas using prospectively-collected long-term survival data. Methods: IDH1/2 mutation status was determined by next-generation sequencing. 1p/19q co-deletion status was determined by Oncoscan and/or 450K methylation data. Overall survival (OS) and progression-free survival (PFS) by marker status were determined by the Cox proportional hazard model and tested using the log-rank test in a post-hoc analysis. Patient pre-treatment characteristics were included as covariates in multivariate analyses. Results: Of all the eligible patients (N=129), 80 (62%) had sufficient quality DNA for both IDH and 1p/19q analyses. Of these 80, 54 (67.5%) were IDHmt, and 26 (32.5%) were IDHwt. Of the 54 IDHmt patients, 26 (32.5% of total, 48% of IDHmt) were IDHmt/codel, and 28 (35% of total, 52% of IDHmt) were IDHmt/non-codel. Both IDHmt subgroups were significantly correlated with longer PFS ( IDHmt/co-del = 8.1yrs (5.2-not reached (NR)); IDHmt/non-codel = 7.5yrs (3.9-11.8); IDHwt = 1.0yr (0.6-1.7), p 〈 0.001) and OS ( IDHmt/co-del = 9.4yrs (8.2-NR); IDHmt/non-codel = 8.8yrs (5.9-NR); IDHwt = 2.3yrs (1.4-3.4), p 〈 0.001) relative to the IDHwt subgroup. Upon univariate and multivariate analyses, both molecular IDHmt subgroup comparisons relative to IDHwt remained significant (p 〈 0.001) even after incorporation of known clinical variables. Conclusions: These analyses suggest that G2 glioma patients harboring IDH1/2 mutations, regardless of co-deletion status, demonstrated longer survival with RT + TMZ relative to IDHwt tumors, although sample size is limited and analyses were post-hoc. These results also support the notion that outcomes for IDHwt high-risk G2 gliomas remain dismal (median = 2.3yrs, similar to G3 anaplastic astrocytoma); these patients should be separated from IDHmt patients in future G2 glioma trials, and warrant novel treatment strategies.

    Abstract: 2008 Background: The primary endpoint of RTOG 0424 was to compare the 3-year survival (OS) of a regimen of concurrent and adjuvant temozolomide (TMZ) and radiotherapy (RT) in a high-risk low-grade glioma (LGG) population to the 3 year (yr) OS rate of the high risk EORTC LGG patients (pts) reported by Pignatti et al (J Clin Oncol 2002;20(8):2076-84). Secondary endpoints were: progression-free survival (PFS), toxicity, neurocognitive and quality of life data and molecular analysis. Methods: Pts with LGG's and 〉 =3 high risk factors (age 〉 = 40, astrocytoma dominant histology, tumor crossing midline, tumor 〉 = 6 cm or preoperative neurological function status 〉 1) were eligible and treated with conformal RT (54 Gy/30 fractions) plus concurrent TMZ 75 mg/m 2 /day for 6 weeks and post-RT TMZ 150-200 mg/m 2 /day days 1-5 q28 days for up to 12 cycles. The study was designed to detect a 43% increase in median survival time (MST) from 40.5 to 57.9 months, and a 20% improvement in 3 yr OS rate from 54% to 65%, at a 10% significance level (1 sided) and 96% power. Results: Between January 2005-August 2009 136 pts were accrued, 129 (75 males, 54 females) were evaluable. Median age was 49 years, 91% had a Zubrod score 0-1 and 69%, 25% and 6% of pts had 3,4 and 5 high risk factors respectively. With a median follow-up time of 4.1 yrs, minimum follow-up of 3 yrs, MST has not yet been reached. Three year OS rate was 73.1% (95%CI:65.3-80.8%), significantly improved from historical control with a p-value 〈 0.0001. No difference in OS rates for pts with 3, 4 or 5 high risk factors was seen. 3 year PFS was 59.2% (95% CI:50.7-67.8%). Grade 3 adverse events (AE) occurred in 43% of pts and grade 4 AE in 10%, primarily hematologic, constitutional or gastrointestinal (nausea, anorexia) toxicity. One patient died of herpes encephalitis. Secondary analyses are ongoing. Radiation Quality Assurance was per protocol/ acceptable in 95% and 74% of pts completed chemotherapy per protocol. Conclusions: The 3 year OS rate of 73.1% for these high risk LGG pts is significantly higher than those reported for historical controls (54%, p 〈 0.0001, one-sided) and the study-hypothesized 65%.

    Abstract: This study investigated the treatment of primary CNS lymphoma with methotrexate, temozolomide (TMZ), and rituximab, followed by hyperfractionated whole-brain radiotherapy (hWBRT) and subsequent TMZ. The primary phase I end point was the maximum tolerated dose of TMZ. The primary phase II end point was the 2-year overall survival (OS) rate. Secondary end points were preirradiation response rates, progression-free survival (PFS), neurologic toxicities, and quality of life. Patients and Methods The phase I study increased TMZ doses from 100 to 150 to 200 mg/m 2 . Patients were treated with rituximab 375 mg/m 2 3 days before cycle 1; methotrexate 3.5 g/m 2 with leucovorin on weeks 1, 3, 5, 7, and 9; TMZ daily for 5 days on weeks 4 and 8; hWBRT 1.2 Gy twice-daily on weeks 11 to 13 (36 Gy); and TMZ 200 mg/m 2 daily for 5 days every 28 days on weeks 14 to 50. Results Thirteen patients (one ineligible) were enrolled in phase I of the study. The maximum tolerated dose of TMZ was 100 mg/m 2 . Dose-limiting toxicities were hepatic and renal. In phase II, 53 patients were treated. Median follow-up for living eligible patients was 3.6 years, and 2-year OS and PFS were 80.8% and 63.6%, respectively. Compared with historical controls from RTOG-9310, 2-year OS and PFS were significantly improved (P = .006 and .030, respectively). In phase II, the objective response rate was 85.7%. Among patients, 66% (35 of 53) had grade 3 and 4 toxicities before hWBRT, and 45% (24 of 53) of patients experienced grade 3 and 4 toxicities attributable to post-hWBRT chemotherapy. Cognitive function and quality of life improved or stabilized after hWBRT. Conclusion This regimen is safe, with the best 2-year OS and PFS achieved in any Radiation Therapy Oncology Group primary CNS lymphoma trial. Randomized trials that incorporate this regimen are needed to determine its efficacy compared with other strategies.

    Abstract: 460 Background: Radiation Therapy Oncology Group (RTOG) 0529 assessed feasibility of dose-painted intensity-modulated radiation therapy (DP-IMRT) to reduce the acute morbidity of chemoradiation with 5-fluorouracil (5FU) and mitomycin-C (MMC) for T2-4N0-3M0 anal cancer. This secondary analysis was performed to identify patient (pt) and treatment factors associated with acute and late gastrointestinal (GI) adverse events (AEs). Methods: RTOG 0529 treatment plans were reviewed to extract dose-volume data for tightly contoured small bowel (SB), loosely contoured anterior pelvic contents (APC), and uninvolved portions of colon outside the clinical target volume (UC). T-tests were performed to evaluate differences in the mean absolute volumes of each critical structure receiving doses ≥ 5 to 60 Gy (V5-V60) in 5 Gy increments between pts with and without ≥ grade (G) 2, acute and late GI AEs, and ≥G3 acute GI AEs using the NCI Common Terminology Criteria, version 3. Acute is defined as ≤ 90 days from the start of treatment and late is 〉 90 days. Additional factors (age, location, gender, race, Zubrod, grade, size, stage, prone vs supine position) were also evaluated in multivariate (MV) logistic regression (acute AEs) or Cox proportional hazards models (late AEs) to evaluate correlation with GI AEs. Results: Among 52 evaluable pts, ≥G2 acute, ≥G2 late, and ≥G3 acute GI AEs were observed in 35, 17, and 10 pts, respectively. Trends (p 〈 0.05) towards statistically significant associations were observed between: ≥G2 acute GI AEs and SB dose (V20-V40); ≥G2 late GI AEs and APC dose (V60); ≥G3 acute GI AEs and APC dose (V5-V25), increasing age, tumor size 〉 4cm, and worse Zubrod. SB and APC dose parameters remained correlated with GI AEs on MV analysis. Treatment in the prone vs supine position correlated with lower SB V10-V35 and APC V5-V20, although no significant differences in GI AEs were observed. Conclusions: Acute and late GI AEs from 5FU/MMC chemoradiation using DP-IMRT correlates with RT dose to the SB and APC. Further analysis is underway to determine critical structure cut-point parameters that may aid treatment plan optimization for anal cancer DP-IMRT.

    Abstract: e17052 Background: Men with localized prostate cancer have many options for initial definitive treatment. In 2015, Cancer Care Ontario Quality Based Procedures (QBP) recommended that men undergoing radical prostatectomy (RP) in Ontario be seen by a radiation oncologist (RO) or discussed at a multidisciplinary case conference (MCC) prior to surgery. An a-priori target rate of 76% was set by QBP, but to our knowledge, has not been reported upon to date. Our objective was to use population-based data to explore factors associated with not receiving RO consult/MCC prior to RP. Methods: Men with localized prostate cancer diagnosed and treated in Ontario, Canada with RP between 2007 and 2017 were identified using administrative data from the Institute for Clinical Evaluative Sciences. Physician billing data was utilized to identify patients who received RO consult/MCC prior to RP. Trends were evaluated using the Cochran-Armitage test. Multivariable logistic regression was used to identify patient and provider factors predictive of RO/MCC prior to RP. Results: 31,467 men with localized prostate cancer underwent RP between 2007 and 2017. Prior to RP, 29.3% of men were seen by RO, 1.0% underwent MCC, and 1.6% had both. RO consult/MCC prior to RP increased from 18.0% in 2007 to 47.8% in 2017 ( p 〈 0.001). On multivariable analysis, the Odds Ratio (OR) of RO consult/MCC prior to RP between the lowest and highest geographic regions (LHINs) was 8.79 (95% CI 6.83–11.32, p 〈 0.001). RO consult/MCC was less likely to occur for patients living further from the nearest cancer center (OR 0.74 per 50km, 95% CI 0.70–0.77, p 〈 0.001) and more likely to occur for men residing in the highest versus lowest income quintile regions (OR 1.42, 95% CI 1.30–1.55, p 〈 0.001). Men with NCCN Low (OR 1.31, 95% CI 1.16–1.47, p 〈 0.001), High (OR 1.20, 95% CI 1.09–1.31, p 〈 0.001) or Very High (OR 1.24, 95% CI 1.11–1.30, p 〈 0.001) risk disease were more likely to receive RO consult/MCC compared to those with favourable-intermediate risk disease. Of the 128 urologists who performed at least 10 RP between 2016 and 2017, RO referral/MCC rate ranged from 0% to 100%, with 31 urologists (24.2%) having ≥76% of their patients seen prior to RP. To meet QBP targets in 2017, an additional 701 men would have needed RO consult/MCC. If all were seen by RO, approximately 2.4 additional full time equivalent RO positions would be needed. Conclusions: Despite increasing rates of utilization, a large proportion of men are not seen by RO or MCC prior to RP in Ontario, Canada. While the largest factors predicting RO consult/MCC discussion appear to be geographic and which urologist performs the RP, these factors are closely intertwined. In addition, these factors may be related to RO availability and radiation system capacity, which would need to be addressed to meet patient demand should QBP consultation rates be mandated to reduce disparities in pre-RP consultation practices.

    Abstract: 4007 Background: NRG/RTOG 0848 is a 2-step study designed to determine whether erlotinib (E) added to gemcitabine (G) (randomized Ph II) & /or adjuvant radiation with concurrent 5-FU or capecitabine following 6 months of systemic chemotherapy (Ph III), improve survival in patients (pts) with resected pancreatic head adenocarcinoma. The erlotinib results are reported here. Methods: Eligible pts include those with resected pancreatic head adenocarcinoma, pathologic stage T1-T3, N0-1, M0; PS 0-1, & CA19-9 ≤ 180 IU/L. Pts in Arms 1 & 2 received G 1 gm/m 2 weekly for 3 weeks in a 28-day cycle for 6 cycles. Pts in Arm 2 also received E 100 mg/day. The primary hypothesis for the E portion was that G+E would increase overall survival (OS) compared to G alone. With a 1-sided alpha of 0.15, 200 OS events provide 80%/90% power to detect a signal for an increase in median OS from 22 to 28.8/30.6 months (mos). OS was estimated by the Kaplan-Meier method & arms compared using the log rank test. The Cox proportional hazards model was used to analyze treatment effect. Results: 336 pts were randomized from 11/17/2009 to 2/28/2014, with 163 pts evaluable for G and 159 for G+E. Median age was 63 years (39-86). Most pts had pathologic T3 disease (78%) & CA19-9 ≤ 90 (93%). There are 32 pts (20%) with grade 4 adverse events (AEs) & 2 pts (1%) with grade 5 AEs on G and 27 (17%) & 3 (2%) on G+E arm, respectively. There are fewer grade ≥ 3 GI AEs on the G arm (22%) as compared to the G+E arm (28%), and 110 (69.2%) & 93 (59.6%) pts received at least 85% of planned G dose for the G & G+E arms, respectively. 58% of E pts received at least 85% of planned E dose. The median follow-up for alive pts is 42.5 mos (min-max: 〈 1-75). With 203 deaths, median & 3-yr OS (95% CI) are 29.9 mos (21.7-33.4) & 39% (30, 45) for G and 28.1 mos (20.7-30.9) & 39% (31, 47) for G+E; log-rank p = 0.62. The hazard ratio (95% CI) comparing OS of G+E to G is 1.04 (0.79- 1.38). Conclusions: The addition of adjuvant E to G did not provide a signal for increased OS in pts with resected pancreatic head cancer compared to G alone. Accrual to the trial is continuing to answer the Ph III radiation question. Clinical trial information: NCT01013649.

    Abstract: 2033 Background: This prospective phase II study tested a methotrexate (MTX), temozolomide (TMZ) and rituximab (RTX) pre-irradiation regimen with hyperfractionated whole brain radiation therapy (hWBRT) followed by post-irradiation TMZ for patients with primary CNS lymphoma (PCNSL). The primary phase II endpoint was the 2-year overall survival (OS) rate compared with the 2-year OS from RTOG 93-10 (MTX, procarbazine, vincristine, whole brain radiation therapy, cytarabine). Secondary endpoints were pre-irradiation chemotherapy tumor response rates (compared to RTOG 93-10), progression free survival (PFS), acute and late neurologic toxicities, and quality of life. Methods: 53 patients (28 women, 25 men), median age 57.5 years, median Zubrod 1 were treated with RTX 375 mg/m 2 3 days prior to first cycle of MTX; 5 cycles of intravenous MTX 3.5 g/m 2 with leucovorin rescue on weeks 1, 3, 5, 7, 9; TMZ 100 mg/m 2 daily for 5 days weeks 4 and 8; hWBRT 1.2 Gy twice daily fractions 5 days/week on weeks 11, 12, 13 for a total of 36 Gy and TMZ 200 mg/m 2 daily for 5 days on weeks 14, 18, 22, 26, 30, 34, 38, 42, 46, 50. Results: Dosing of pre-irradiation temozolomide at 100 mg/m 2 was determined in the phase I portion of the study. With a median follow-up of 3.6 years, 2-year OS and PFS rates were 80.8% and 63.6%, respectively. Compared with historical controls from RTOG 93-10, 2-year OS and PFS were significantly improved (p = 0.006 and 0.03). The overall response rate to the pre-irradiation chemotherapy was 37.7% (complete response 11.3%, partial response 26.4%). 38% experienced grade 3 and 25% experienced grade 4 toxicities before the start of hWBRT. 33% experienced grade 3 and 21% experienced grade 4 toxicities attributable to post-hWBRT chemotherapy. Conclusions: The combination of MTX, TMZ, RTX followed by hWBRT and TMZ for PCNSL is safe with demonstrated improved 2 year OS and PFS compared with RTOG 93-10. Further investigations regarding the role of hWBRT and post-hWBRT TMZ are indicated. This project was supported by RTOG grant U10 CA21661 and CCOP grant U10 CA37422 from the National Cancer Institute (NCI) and Schering-Plough. Clinical trial information: NCT00068250.

    Abstract: Despite advances in surgery and pharmacotherapy, there remains significant residual ischemic risk after coronary artery bypass grafting surgery. Methods: In REDUCE-IT (Reduction of Cardiovascular Events With Icosapent Ethyl–Intervention Trial), a multicenter, placebo-controlled, double-blind trial, statin-treated patients with controlled low-density lipoprotein cholesterol and mild to moderate hypertriglyceridemia were randomized to 4 g daily of icosapent ethyl or placebo. They experienced a 25% reduction in risk of a primary efficacy end point (composite of cardiovascular death, myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina) and a 26% reduction in risk of a key secondary efficacy end point (composite of cardiovascular death, myocardial infarction, or stroke) when compared with placebo. The current analysis reports on the subgroup of patients from the trial with a history of coronary artery bypass grafting. Results: Of the 8179 patients randomized in REDUCE-IT, a total of 1837 (22.5%) had a history of coronary artery bypass grafting, with 897 patients randomized to icosapent ethyl and 940 to placebo. Baseline characteristics were similar between treatment groups. Randomization to icosapent ethyl was associated with a significant reduction in the primary end point (hazard ratio [HR], 0.76 [95% CI, 0.63–0.92] ; P =0.004), in the key secondary end point (HR, 0.69 [95% CI, 0.56–0.87]; P =0.001), and in total (first plus subsequent or recurrent) ischemic events (rate ratio, 0.64 [95% CI, 0.50–0.81]; P =0.0002) compared with placebo. This yielded an absolute risk reduction of 6.2% (95% CI, 2.3%–10.2%) in first events, with a number needed to treat of 16 (95% CI, 10–44) during a median follow-up time of 4.8 years. Safety findings were similar to the overall study: beyond an increased rate of atrial fibrillation/flutter requiring hospitalization for at least 24 hours (5.0% vs 3.1%; P =0.03) and a nonsignificant increase in bleeding, occurrences of adverse events were comparable between groups. Conclusions: In REDUCE-IT patients with a history of coronary artery bypass grafting, treatment with icosapent ethyl was associated with significant reductions in first and recurrent ischemic events.
