e14042 Background: Optic gliomas are the most common tumors of the optic pathway, comprising about 1% of all intracranial tumours. Here we present the clinical characteristics and the outcome of patients with optic glioma at our institution. Methods: Seventy two patients diagnosed and followed up at a pediatric cancer center in Ankara, Turkey between January 1, 2008 and December 31, 2020 were included in this analysis. The clinical features and outcome of patients were recorded from patient files and hospital information system retrospectively. Results: The median age at the time of diagnosis was 3.5 years (4-157 months), the female/male ratio was 1.3. Fourteen children (19%) were asymptomatic and tumors were detected with routine surveillance, and 58 (81%) had symptoms (the most common being proptosis in 16 patients (22%)). The most common site of optic glioma was the intraorbital region (31%). Fourty patients (55%) had neurofibromatosis type 1 (NF-1). Five patients had histopathological diagnoses; 3 pilomyxoid astrocytoma, 2 pilocytic astrocytoma. Children were treated if they had tumor progression on MRI and/or worsening visual acuity. Twenty seven (38%) children were observed without any therapy, 6 patients (8%) received radiation and chemotherapy, 4 patients (5%) received radiation only, and 35 patients (49%) received chemotherapy only. Treatment regimens for the 41 children who received chemotherapy included carboplatin/etoposide (17), cisplatin/etoposide (18), carboplatin/vincristine (5), and temozolomide (1). The 5-year progression-free survival (PFS) and overall survival (OS) were 64% and 90%, respectively with a 31 month median follow-up. The 5 year PFS was significantly lower in patients with optic tract-hypothalamic-chiasmatic involvement (34%) than orbital involvement (83%) (p=0.013). Five year PFS was significantly higher in patients with NF-1 (80%) than patients without NF-1(46%) (p=0.027) and significantly lower in patients diagnosed at <3 years old (37%) (p=0.05). Five patients died of disease, and one died of infection after chemotherapy. Two patients treated with platin (1 carboplatin, 1 cisplatin) developed ototoxicity. One patient with NF-1 developed Moya-Moya disease. Two patients developed multiple pituitary hormone deficiencies and one patient developed precocious puberty during follow-up. No secondary malignancy was observed. Conclusions: The management of optic glioma remains challenging. Although the overall survival for children with this disease is excellent, progression of disease is frequent, particularly in those children without NF-1, younger children and non-orbital tumors. This study from Turkey showed comparable results with high-income countries. Further studies with longer follow-up periods are needed to find appropriate treatment strategies.

Abstract INTRODUCTION Stereotactic radiosurgery (SRS) commenced at Guy’s Cancer Hospital in August 2017. We report our first seventeen months’ data (August 2017 to December 2018) for brain metastases SRS. METHOD Patients referred via Neuro Oncology MDT were assessed for suitability for SRS via clinical review and 1mm-slice MRI. Treatment was planned on Eclipse v15.6 and delivered using Truebeam STx Linac(FFF) and Align RT v5.1 for matching. Dose prescription, according to departmental protocol, was set at 100% isodose, ranging from 18Gy to 25Gy, with fractionation varying from single to five fractions depending on factors including size, volume and locations. Post-treatment, patients were discharged back to their primary treating team for 3-monthly MRI. RESULTS Between Aug-17 to Dec-18, 70 patients with brain metastases were treated with a total of 122 lesions. Mean age was 66 years (range 37-93) and Median follow-up 9 months. Primary tumour sites mainly included lung 34(48.5%), breast 16(22.8%) and melanoma 17(24.3%). Brain-only metastases, including small volume primary with brain metastases were found in 85.4% cases, whilst visceral disease with brain metastases were found in 14.5% patients. Out of 122 lesions, the majority were treated in the primary setting; 95(77.8%) vs 27(22.1%) in the adjuvant setting. At 9-months follow up, local failure rate was in 26(21.3%) sites and 17 new sites in distant brain appeared. 31(44.2%) patients received no systemic therapy after SRS, whilst immunotherapy was received by 14(20%), with the remaining receiving hormones or chemotherapy. Median Overall Survival was 9.2 months (95% CI: 4.5-13.8) and Median progression-free survival was 5.9 months (95% CI: 7.0-10.4). CONCLUSION Overall Survival results were encouraging with initial auditing proving SRS as effective approach. Local control rates correlate well with randomized control trials results for SRS in brain metastases.

Abstract Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare subtype of lymphoma that, like other Hodgkin lymphomas, has historically been treated aggressively. However, in most cases, NLPHL has an indolent course, which raises the question of to what extent these patients require aggressive upfront treatment. We describe the management and outcomes of consecutive NLPHL patients diagnosed at Memorial Sloan Kettering Cancer Center (MSK), with a focus on evaluating active surveillance. All patients aged 16 years or older diagnosed and followed at MSK between 1974 and 2016 were included. Treatment outcomes were compared between management with active surveillance and other strategies. We identified 163 consecutive patients who were treated with radiotherapy alone (46%), active surveillance (23%), chemotherapy (16%), combined modality (12%), or rituximab monotherapy (4%). Median follow-up was 69 months. Five-year progression-free survival (PFS), second PFS (PFS2), and overall survival (OS) estimates were 85% (95% confidence interval [CI], 78-90), 97% (95% CI, 92-99), and 99% (95% CI, 95-100), respectively. Only 1 of 7 deaths was lymphoma related. Patients managed with active surveillance had slightly shorter PFS than those receiving any active treatment, with 5-year PFS of 77% (95% CI, 56-89) vs 87% (95% CI, 79-92; P = .017). This difference did not translate into better PFS2 or OS. Only 10 patients managed with active surveillance (27%) eventually required treatment, after a median of 61 months, and none died. NLPHL has an excellent prognosis. Within the limitations of a retrospective analysis, active surveillance is a viable initial management strategy for selected NLPHL patients.

ObjectiveThe aim of the study was to report on the oncologic outcome of the disease spread to celiac lymph nodes (CLNs) in advanced-stage ovarian cancer patients.MethodsAll patients who had CLN resection as part of their cytoreductive surgery for epithelial ovarian, fallopian, or primary peritoneal cancer were identified. Patient demographic data with particular emphasis on operative records to detail the extent and distribution of the disease spread, lymphadenectomy procedures, pathologic data, and follow-up data were included.ResultsThe median follow-up was 26.3 months. The median overall survival values in the group with positive CLNs and in the group with negative CLNs were 26.9 months and 40.04 months, respectively. The median progression-free survival values in the group with metastatic CLNs and in the group with negative CLNs were 8.8 months and 20.24 months, respectively (P = 0.053). Positive CLNs were associated with progression during or within 6 months after the completion of chemotherapy (P = 0.0044). Tumor burden and extensive disease distribution were significantly associated with poor progression-free survival, short-term progression, and overall survival. In multivariate analysis, only the CLN status was independently associated with short-term progression.ConclusionsDisease in the CLN is a marker of disease severity, which is associated to a high-risk group of patients with presumed adverse tumor biology, increased risk of lymph node progression, and worst oncologic outcome.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC). Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.

e19531 Background: The outcome of patients with PTCL, NOS is generally very poor, and the identification of biologically rational targets, which may translate into effective and non-toxic treatment strategies, is a high priority. The pro-survival BCL-2 family members BCL-2, BCL-XL (BCL2L1), BCL-W (BCL2L2), BCL2A1 and MCL-1 contribute to tumor maintenance, progression, and chemo-resistance across a range of cancers, but their contributions in PTCL, NOS are poorly understood. Methods: Patients with PTCL, NOS treated between 09/2000 and 09/2019 and with available tissue biopsy were included in the study. Diagnosis was retrospectively confirmed by two expert hematopathologists. BCL-2, BCL-XL, BCL-W, BCL2A1 and MCL-1 expression was assessed by immunohistochemistry (IHC), and the percentage of positive tumor cells assessed by standard microscopy. The 2014 Lugano Classification was used to define response to therapy. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method, and were compared using log-rank test between patient groups. Results: Twenty-seven patients were included in the study: 67% were male, 52% ≥ 65 year old, and 48% had stage IV disease; 59% were previously treated and 41% received > 2 lines of therapy, including stem cell transplant (SCT) in 19%. The median expression of BCL-2, BCL-XL, BCL-W, BCL2A1 and MCL-1 by IHC was: 30% (range: 0-100%), 10% (range: 0-90%), 100% (range: 40-100%), 20% (range: 0-90%), and 70% (range: 1-100%), respectively. BCL-2A1 was significantly higher in previously treated patients (35% vs 5%, p = 0.02), and in those who had previously received > 2 lines of therapy (40% vs 5%, p = 0.02). Twenty-four (89%) patients were treated after tissue biopsy, 17 (63%) with chemotherapy, 7 (26%) with biological therapy, and 6 (22%) received subsequent SCT. Five (24%) patients achieved complete remission (CR); only BCL-W associated with response, a higher expression (quartiles 3 and 4) being observed among patients not achieving CR (median 100% vs 90%, p = 0.07). After a median follow-up of 28 months (95% CI, 14-42 months), 22 (81%) patients progressed or died, and median PFS was 4 months (95% CI, 2-6 months); only BCL-W associated with PFS, a shorter median PFS being observed for patients with higher expression (3 months vs 7 months, p = 0.001). At most recent follow-up, 17 (63%) patients died, and median OS was 6 months (95% CI, 1-12 months). only BCL-W associated with OS, a shorter median OS being observed for patients with higher expression (4 months vs not reached, p = 0.004). Conclusions: High expression of BCL-W associates with significantly worse outcome in patients with PTCL, NOS. While clinical trials investigating the safety and efficacy of BCL-2 inhibition in PTCL, NOS are ongoing, these results suggest that concomitant BCL-W inhibition may be beneficial, and functional studies aimed at confirming these findings are highly needed.

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

The role of cytoreductive nephrectomy (CN) in treatment of locally advanced or metastatic renal cell carcinoma (mRCC) in the era of targeted therapies (TT) is still not clearly defined. The study population consisted of 730 patients with synchronous mRCC. The RenIS (Renal carcinoma Information System) registry was used as the data source. The CN/TT cohort included patients having CN within 3 months from the mRCC diagnosis and subsequently being treated with TT, while the TT cohort included patients receiving TT upfront. Median progression-free survival from the first intervention was 6.7 months in the TT arm and 9.3 months in the CN/TT patients (p < 0.001). Median overall survival was 14.2 and 27.2 months, respectively (p < 0.001). Liver metastasis, high-grade tumor, absence of CN, non-clear cell histology, and MSKCC (Memorial Sloan-Kettering Cancer Center) poor prognosis status were associated with adverse treatment outcomes. According to the results of this retrospective study, patients who underwent CN and subsequently were treated with TT had better outcomes compared to patients treated with upfront TT. The results of the study support the use of CN in the treatment algorithm for mRCC.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Purpose There is no consensus on the optimal systemic treatment of patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. The IELSG-19 phase III study, to our knowledge, was the first such study to address the question of first-line treatment in a randomized trial. Patients and Methods Eligible patients were initially randomly assigned (1:1 ratio) to receive either chlorambucil monotherapy (6 mg/m2/d orally on weeks 1 to 6, 9 to 10, 13 to 14, 17 to 18, and 21 to 22) or a combination of chlorambucil (same schedule as above) and rituximab (375 mg/m2 intravenously on day 1 of weeks 1, 2, 3, 4, 9, 13, 17, and 21). After the planned enrollment of 252 patients, the protocol was amended to continue with a three-arm design (1:1:6 ratio), with a new arm that included rituximab alone (same schedule as the combination arm) and with a final sample size of 454 patients. The main end point was event-free survival (EFS). Analysis of chlorambucil versus the combination arm was performed and reported separately before any analysis of the third arm. Results At a median follow-up of 7.4 years, addition of rituximab to chlorambucil led to significantly better EFS (hazard ratio, 0.54; 95% CI, 0.38 to 0.77). EFS at 5 years was 51% (95% CI, 42 to 60) with chlorambucil alone, 50% (95% CI, 42 to 59) with rituximab alone, and 68% (95% CI, 60 to 76) with the combination ( P = .0009). Progression-free survival was also significantly better with the combination ( P = .0119). Five-year overall survival was approximately 90% in each arm. All treatments were well tolerated. No unexpected toxicities were recorded. Conclusion Rituximab in combination with chlorambucil demonstrated superior efficacy in mucosa-associated lymphoid tissue lymphoma; however, improvements in EFS and progression-free survival did not translate into longer overall survival.
