2063 Background: Gangliogliomas (GG) represent less than 1% of primary brain tumors in adults. Little is known regarding prognostic features, clinical characteristics or the impact of treatment on patient (pt) outcomes. Methods: In this IRB approved retrospective study, our neuro-oncology longitudinal database was screened for pts with GG from 1992-2012. 67 adult pts (age>18) were identified. Results: 60 pts presented with low grade GG and 7 with anaplastic GG. The median age at diagnosis was 27 years (18-59). 22 pts developed recurrent disease (18 low grade and 4 high grade) with a median time to recurrence of 87 weeks from surgery. 7 of the pts with low grade GG had malignant transformation to a malignant tumor (anaplastic GG or GBM). 22 pts received radiation therapy, 16 at diagnosis. 14 pts received chemotherapy at recurrence. Pts with incomplete resections or higher grade tumors were more likely to receive chemotherapy or radiation. The median overall survival (OS) time for these pts was not reached with a median follow-up time of 4.6 years. The 2-, 5- and 10-year OS were 98%, 87%, and 76%. Factors on univariate analysis that were significantly associated with OS were KPS at presentation (HR 10.1; 95% CI 2.6, 39.1; p = 0.0008), extent of resection (EOR) (biopsy vs gross total; HR 12.1; 95% CI 2.3, 63.6; p = 0.003), histologic grade (Grade 1-2 vs Grade 3-4; HR 0.06; 95% CI 0.01, 0.3; p = 0.0002), and seizure control following surgery (Engel I vs Engel 2-3; HR 0.1; 95% CI 0.01, 0.9; p = 0.02). Factors on univariate analysis that were significantly associated with progression free survival (PFS) were EOR (biopsy vs gross total; HR 4.0; 95% CI 1.4, 11.9; p = 0.01) and histologic grade (Grade 1-2 vs .Grade 3-4; HR 0.3; 95% CI 0.08, 0.8; p = 0.02). On multivariate analysis, EOR is most significant for PFS (p = 0.01), while tumor grade is most significant for OS (p = 0.004). Conclusions: While GG have an excellent prognosis, malignant histological grade, diagnosis with a biopsy only, poor initial KPS, and presence of seizures following surgery could indicate a worse prognosis. The role of chemotherapy and radiation therapy for incompletely resected or inaccessible low grade GG is unclear.

Abstract Abstract 2704 Background: MR has improved the outcome and progression-free survival (PFS) in patients with follicular lymphoma (FL) in front-line and relapsed settings. However, maintenance schedules have been empirically designed based on either B-cell depletion kinetics or rituximab levels, with no consensus on the optimal regimen. Overall, toxicities have been predictable and tolerable but the impact of MR schedule on toxicities has not been previously reported and could influence selection of maintenance regimens. Methods: Using PubMed, prospective clinical trials employing MR were identified. Data presented in abstract form or at meetings were deemed incomplete and thus excluded. Data were analyzed from published manuscripts as percentages of subjects experiencing an adverse event (AE). Percentages were considered as the unit of analysis as this adjusted for the uneven sample sizes. Data were collected for overall Grade 3 and/or Grade 4 toxicity (AE reported at any phase of treatment) and was further categorized as AE occurring during initial treatment or during MR. Grade 1 and 2 toxicities were excluded from meta-analysis, given lack of consistent reporting. No grade 5 toxicities were reported. The incidence, severity, and type of toxicity was analyzed by type of induction (Rituximab (R) vs. R plus chemotherapy), histology (FL vs. FL plus other LG-NHL), setting (front-line vs. relapsed), and MR schedule (one dose every 2 months vs. one dose every 3 months vs. 4 doses every 6 months). Results: Nine clinical trials involving 1,928 patients were included in this Meta analysis (4 of which were randomized controlled in the MR phase). Of those, 1,004 patients received MR. The mean percentage of Grade 3/4 toxicities during any phase of treatment was 26% (95% CI = 0.12–51.88) but when restricted to the MR phase; it was 12.88% (95% CI = 6.50–19.26). Toxicities were numerically higher in patients receiving R induction plus chemotherapy versus R induction alone and in patients receiving MR for relapsed disease versus newly diagnosed patients, but did not reach statistical significance (P = 0.661 and 0.517, respectively). However, patients receiving MR every 2 months were significantly more likely to develop grade 3 and 4 toxicities compared to patients receiving MR every 6 months (P = 0.005). No statistical differences were demonstrated between the 2 vs. 3 months schedules or when comparing the 3 vs. 6 months schedules (P = 0.342 and 0.267, respectively) (Table 1). Statistically significant differences were also found in studies restricted to FL versus others allowing non-FL histologies (P = 0.025) with the FL patients experiencing more toxicity than others. The most frequently reported toxicities were neutropenia and infections. There were no treatment-related deaths in any of the arms. Conclusions: Approximately 13% of patients receiving MR experience grade 3 and/or 4 toxicities, mainly consisting of neutropenia and infections. MR given every 6 months appears to provide the least grade 3 and 4 toxicities. There is a suggestion of increased toxicity in FL histologies. It is important to note that this meta-analysis did not address efficacy and only a true comparative trial can definitively establish the relative risk/benefit ratios amongst MR schedules.

Abstract BACKGROUND: The efficacies of adjuvant stereotactic radiosurgery (SRS) and external beam radiation therapy (EBRT) for atypical meningiomas (AMs) after subtotal resection (STR) remain unclear. OBJECTIVE: To analyze the clinical, histopathological, and radiographic features associated with progression in AM patients after STR. METHODS: Fifty-nine primary AMs after STR were examined for predictors of progression, including the impact of SRS and EBRT, in a retrospective cohort study. RESULTS: Twenty-seven patients (46%) progressed after STR (median, 30 months). On univariate analysis, spontaneous necrosis positively (hazard ratio = 5.2; P = .006) and adjuvant radiation negatively (hazard ratio = 0.3; P = .009) correlated with progression; on multivariate analysis, only adjuvant radiation remained independently significant (hazard ratio = 0.3; P = .006). SRS and EBRT were associated with greater local control (LC; P = .02) and progression-free survival (P = .007). The 2-, 5-, and 10-year actuarial LC rates after STR vs STR/EBRT were 60%, 34%, and 34% vs 96%, 65%, and 45%. The 2-, 5-, and 10-year actuarial progression-free survival rates after STR vs STR/EBRT were 60%, 30%, and 26% vs 96%, 65%, and 45%. Compared with STR alone, adjuvant radiation therapy significantly improved LC in AMs that lack spontaneous necrosis (P = .003) but did not improve LC in AMs with spontaneous necrosis (P = .6). CONCLUSION: Adjuvant SRS or EBRT improved LC of AMs after STR but only for tumors without spontaneous necrosis. Spontaneous necrosis may aid in decisions to administer adjuvant SRS or EBRT after STR of AMs.

Abstract OBJECTIVE To develop outcome predictors after stereotactic radiosurgery (SRS) in patients with intracranial ependymomas who had received previous fractionated radiation therapy, we compared tumor control, survival, and complications with tumor grade, volume, age of patients, and imaging characteristics. METHODS We retrospectively reviewed records of 39 consecutive ependymoma patients who underwent SRS for 56 tumors. The median patient age was 22.8 years (range, 2.9–71.1 years). All patients had previous surgical resection of their ependymomas followed by radiotherapy, and 14 patients underwent previous chemotherapy. Twenty-five patients had low-grade ependymomas (34 tumors), and 14 patients had anaplastic ependymomas (22 tumors). The median radiosurgery target volume was 3.6 cm3 (range, 0.1–36.8 cm3), and the median margin dose was 15.0 Gy (range, 10–22 Gy). RESULTS At a median of 23.5 months after SRS (range, 6.1–155.2 months), 25 patients died as a result of metastases (12 patients) or disease progression (13 patients). The overall survival rates after SRS were 60.1, 36.1, and 32.1% at 1, 3, and 5 years, respectively. The progression-free survival rates after SRS at 1, 3, and 5 years were 81.6, 45.8, and 45.8%, respectively, for all grades of ependymomas. Lower histological tumor grade was not significantly associated with better progression-free survival (P = 0.725). Factors associated with an improved progression-free survival included smaller tumor volume and homogeneous tumor contrast enhancement in low-grade ependymomas. CONCLUSION SRS provides another management option for patients with residual or recurrent ependymomas that have failed surgery and radiation therapy. Predictors of response include smaller volume and homogeneous contrast enhancement.

Background. We previously showed that grading can prognosticate the outcome of retroperitoneal liposarcoma (LPS). In the present study, we aimed to explore the impact of pathological stratification using grading on the clinical outcomes of patients with advanced well-differentiated LPS (WDLPS) and dedifferentiated LPS (DDLPS) treated with trabectedin. Patients: We included patients with advanced WDLPS and DDLPS treated with trabectedin at the Fondazione IRCCS Istituto Nazionale dei Tumori between April 2003 and November 2019. Tumors were categorized in WDLPS, low-grade DDLPS, and high-grade DDLPS according to the 2020 WHO classification. Patients were divided in two cohorts: Low-grade (WDLPS/low-grade DDLPS) and high-grade (high-grade DDLPS). Results: A total of 49 patients were included: 17 (35%) in the low-grade cohort and 32 (65%) in the high-grade cohort. Response rate was 47% in the low-grade cohort versus 9.4% in the high-grade cohort (logistic regression p = 0.006). Median progression-free survival (PFS) was 13.7 months in the low-grade cohort and 3.2 months in the high-grade cohort. Grading was confirmed as an independent predictor of PFS in the Cox proportional-hazards regression multivariable model (adjusted hazard ratio low-grade vs. high-grade: 0.45, 95% confidence interval: 0.22–0.94; adjusted p = 0.035). Conclusions: In this retrospective case series, sensitivity to trabectedin was higher in WDLPS/low-grade DDLPS than in high-grade DDLPS. If confirmed in larger series, grading could represent an effective tool to personalize the treatment with trabectedin in patients with advanced LPS.

In the RECOURSE trial which lead to its accreditation, Lonsurf (trifluridine/tipiracil) was shown to extend progression free survival (PFS) by 1.8 months in metastatic colorectal cancer. This Trust audit aims to assess the average quantity of cycles of Lonsurf received by participants and the length of time it extends PFS. Similarly, to identify how many participants required a dose-reduction or experienced toxicities which necessitated supportive therapies. Quantitative data was collected retrospectively from all participants who had received ≥1 cycle of Lonsurf from The Clatterbridge Cancer Centre (CCC) from 2016 until June 2020. Participant electronic patient records were accessed to identify toxicity grading, length of treatment received, the date progression was identified, if dose reductions were applied and if supportive therapies were administered. Lonsurf extends PFS in patients with metastatic colorectal cancer at CCC by 3.0 months (95% CI: 2.73–3.27) and average treatment length was 2.4 months. However, 78 participants (41.5%) received a dose reduction due to toxicities. A total of 955 toxicities were recorded by participants; the most commonly reported toxicities irrespective of grade were fatigue (33.8%), diarrhoea (13.8%) and nausea (12.3%). The most common grade ≥3 toxicities were constipation and infection. The most frequently utilised supportive therapies were loperamide (49.6%) and domperidone (49.1%). Granulocyte colony stimulating factor (GCSF) was required by patients on 5 occasions (0.3%) in total. Lonsurf extends median PFS in patients with metastatic colorectal cancer by 3.0 months. The most common grade ≥3 toxicities which necessitated supportive therapies or a dose reduction were gastrointestinal and infection.

359 Background: Statins are HMG-CoA inhibitors that regulate several mechanisms involved in tumor growth, including mitochondrial metabolism, activation of oncogenic signaling pathways, and immune modulation. Population-based studies showed that statin intake may be negatively associated with RCC onset. The impact of statins on response to immunotherapy in mRCC is unknown. Herein we study the association between statin administration and outcomes in patients with mRCC treated with nivolumab in the NIVOREN-GETUG AFU 26 phase II trial (NCT03013335). Methods: Patients with mRCC who failed previous VEGFR inhibitors were included. We assessed nivolumab activity, including objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) according to statin intake at baseline. Toxicity was assessed using CTCAE v4.0. Results: Overall,133 patients were treated with statins at baseline among 702 evaluable for concomitant therapies (19%). Among them, median age was 68 (49-90), 84% were male, 85% had a performance status ≥ 80%, 42% were overweight and 20% obese. Patients treated with statins had mostly good (23%) or intermediate (58%) IMDC risk, 64% had grade 3 or 4 tumors, and nivolumab was given in a third line setting or more in 55%. Median follow-up was 23.9 months (95%CI 23.0-24.5) in the overall cohort. The ORR was 26% in patients treated with statins, PFS 5.0 months (CI95% 3.0 – 5.5), OS 27.9 months (CI95% 19.4-30.3). Outcomes of patients with or without statins did not differ significantly. Similar rates of grade 3-5 TRAE were reported in patients with (20%) or without (18%) statin intake. Conclusions: This is the first study to evaluate statin intake and outcomes with nivolumab in patients with mRCC. Despite numerically higher ORR, statins were not significantly associated with improved outcomes. These data require other analyzes considering other factors such as BMI and other comorbidities. Further studies may help better understand the interplay between immunity and metabolic reprogramming in RCC.

PURPOSE Reducing radiation treatment dose could improve the quality of life (QOL) of patients with good-risk human papillomavirus–associated oropharyngeal squamous cell carcinoma (OPSCC). Whether reduced-dose radiation produces disease control and QOL equivalent to standard chemoradiation is not proven. PATIENTS AND METHODS In this randomized, phase II trial, patients with p16-positive, T1-T2 N1-N2b M0, or T3 N0-N2b M0 OPSCC (7th edition staging) with ≤ 10 pack-years of smoking received 60 Gy of intensity-modulated radiation therapy (IMRT) over 6 weeks with concurrent weekly cisplatin (C) or 60 Gy IMRT over 5 weeks. To be considered for a phase III study, an arm had to achieve a 2-year progression-free survival (PFS) rate superior to a historical control rate of 85% and a 1-year mean composite score ≥ 60 on the MD Anderson Dysphagia Inventory (MDADI). RESULTS Three hundred six patients were randomly assigned and eligible. Two-year PFS for IMRT + C was 90.5% rejecting the null hypothesis of 2-year PFS ≤ 85% ( P = .04). For IMRT, 2-year PFS was 87.6% ( P = .23). One-year MDADI mean scores were 85.30 and 81.76 for IMRT + C and IMRT, respectively. Two-year overall survival rates were 96.7% for IMRT + C and 97.3% for IMRT. Acute adverse events (AEs) were defined as those occurring within 180 days from the end of treatment. There were more grade 3-4 acute AEs for IMRT + C (79.6% v 52.4%; P < .001). Rates of grade 3-4 late AEs were 21.3% and 18.1% ( P = .56). CONCLUSION The IMRT + C arm met both prespecified end points justifying advancement to a phase III study. Higher rates of grade ≥ 3 acute AEs were reported in the IMRT + C arm.

AbstractNumerous studies have analysed the clinical efficacies of hypomethylating agents (HMAs) in patients with myelodysplastic syndromes (MDS). However, reports that compare the two HMAs, decitabine and azacitidine, in patients with lower-risk (low and intermediate-1) MDS are limited. We compared 5-day decitabine and 7-day azacitidine regimens in terms of treatment responses, survival outcomes, and adverse events in patients with lower-risk MDS with poor prognostic features. The overall response rates (ORRs) were 67.2% and 44.0% in the patients treated with decitabine and azacitidine, respectively (P = 0.014). While the median progression-free survival (PFS) was significantly better in the patients treated with decitabine than in those treated with azacitidine (P = 0.019), no significant differences in event-free and overall survival rates were observed between the two groups. Multivariate analysis revealed that compared with azacitidine treatment, decitabine treatment is significantly associated with a higher ORR (P = 0.026) and longer PFS (P = 0.037). No significant differences were observed in the incidence of grade 3 or higher haematologic adverse events in response to the two HMAs. In conclusion, in lower-risk MDS, especially with poor prognostic features, ORR and PFS were significantly better with 5-day decitabine treatment than with 7-day azacitidine treatment, with comparable safety.

Abstract Background Management of unresectable pediatric low-grade glioma and glioneuronal tumor (LGG/LGGNT) is controversial. There are no validated prognostic features to guide use of radiation therapy (RT). Our study aimed to identify negative prognostic features in patients treated with RT using clinicopathologic and molecular data and validate these findings in an external dataset. Methods Children with non-metastatic, biopsy-proven unresectable LGG/LGGNT treated with RT at a single institution between 1997 and 2017 were identified. Recursive partitioning analysis (RPA) was used to stratify patients into low- and high-risk prognostic groups based on overall survival (OS). CNS9702 data were used for validation. Results One hundred and fifty patients met inclusion criteria. Median follow-up was 11.4 years. RPA yielded low- and high-risk groups with 10-year OS of 95.6% versus 76.4% (95% CI: 88.7%–98.4% vs 59.3%–87.1%, P = 0.003), respectively. These risk groups were validated using CNS9702 dataset (n = 48) (4-year OS: low-risk vs high-risk: 100% vs 64%, P &lt; 0.001). High-risk tumors included diffuse astrocytoma or location within thalamus/midbrain. Low-risk tumors included pilocytic astrocytoma/ganglioglioma located outside of the thalamus/midbrain. In the subgroup with known BRAF status (n = 49), risk stratification remained prognostic independently of BRAF alteration (V600E or fusion). Within the high-risk group, delayed RT, defined as RT after at least one line of chemotherapy, was associated with a further decrement in overall survival (P = 0.021). Conclusion A high-risk subgroup of patients, defined by diffuse astrocytoma histology or midbrain/thalamus tumor location, have suboptimal long-term survival and might benefit from timely use of RT. These results require validation.
