Abstract
7528 Background: Hodgkin lymphoma (HL) is a rare disease that commonly occurs in adolescents and young adults (AYAs) which is typically defined as 15 to 39 years. Given their young age at presentation, key factors in treatment selection include a high cure rate and limiting long-term toxicities. Brentuximab vedotin (Adcetris®; A) is a CD30-directed ADC approved in combination with doxorubicin, vinblastine, and dacarbazine chemotherapy (A+AVD) for adults with previously untreated stage III/IV cHL based on results from the phase 3 ECHELON-1 trial. Recent 5-year data demonstrated a significantly improved PFS per investigator (INV) vs doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) (HR, 0.69; 95% CI, 0.54–0.9; P = 0.003) (Straus 2020). Here we describe key efficacy and safety results for AYA pts enrolled in ECHELON-1. Methods: ECHELON-1 (N = 1334) is a global, open-label, multicenter, randomized trial of pts with previously untreated stage III/IV cHL. A total of 771 AYAs (57.8%) received either A+AVD (n = 396) or ABVD (n = 375) with a PET scan after cycle 2 (PET2). An analysis of PFS (time from randomization to progression or death from any cause) per INV was conducted. Results: After a median follow-up of 60.7 months (95% CI, 60.4-61.0), there was a 36% reduction in the risk of progression or death in AYAs receiving A+AVD vs ABVD (HR 0.64; 95% CI, 0.45-0.92; P = 0.013) with a 5-year PFS of 86.3% vs 79.4%, respectively, similar to the ITT population. The PFS benefit of A+AVD vs ABVD was independent of PET2 status; PET2 positivity (Deauville 4-5) was 6% and 8%, respectively. On the A+AVD arm, 81 AYAs (20%) had at least 1 subsequent anticancer therapy vs 96 AYAs (26%) on the ABVD arm; 26 AYAs (7%) received subsequent high dose chemotherapy and autologous stem cell transplant vs 32 AYAs (9%) on the A+AVD and ABVD arms, respectively. Resolution or improvement of peripheral neuropathy (PN) were similar in both arms; 224 AYAs (88%) on the A+AVD had resolution or improvement of PN vs 133 AYAs (89%) on the ABVD arm. Ongoing PN was predominantly Gr 1 (62%) and Gr 2 (26%), with 8 AYAs (13%) on the A+AVD arm and 1 AYA (5%) on the ABVD arm reporting ongoing Gr 3 PN. Finally, 7 AYAs (1.8%) and 5 AYAs (1.4%) on the A+AVD and ABVD arms, respectively, reported a secondary malignancy. Subsequent pregnancies were reported in female pts (44 A+AVD; 26 ABVD) and partners of male pts (31 A+AVD; 30 ABVD). No stillbirths were reported. All but 1 pt in each arm was < 40. Conclusions: Consistent with the ITT population, AYAs treated with A+AVD compared to ABVD had a durable PFS benefit at this significant 5-year milestone. No impact on the rate of secondary malignancies and a numerically greater number of pregnancies were observed, outcomes of interest to AYAs. Additionally, the majority of PN events improved or resolved over time. A+AVD should be considered a treatment option for AYAs with stage III/IV cHL. Clinical trial information: NCT01712490.

Abstract
e19518 Background: Classical Hodgkin lymphoma (cHL) is considered a highly curable cancer. With standard combination chemotherapy regimens, long-term survival exceeds 95% for limited-stage and 85% for advanced-stage patients. Despite these excellent outcomes some patients delay or decline conventional treatment for cHL. We retrospectively assessed the impact of initial treatment refusal on outcomes of patients with cHL in British Columbia (BC). Methods: Using the BC Cancer Lymphoid Cancer Database, we identified all patients aged 18-70 diagnosed between 1st Jan 1999- 31st Dec 2020 that had documented treatment refusal at initial presentation (‘refusers’ defined as not receiving or delaying treatment > 16 weeks). We identified a control cohort (min. 3 controls/refuser) treated within 8 weeks of diagnosis, matched for age, stage, diagnosis date within 3 years, and blinded for outcome. All patients had centrally reviewed biopsies and were treated with ABVD or ABVD-like regimens +/- radiotherapy if appropriate. Patient and disease characteristics at baseline and at time of treatment were analyzed with Chi-squared test and one-way ANOVA test. The Kaplan-Meier method was used to assess progression-free survival (PFS) and overall survival (OS), and statistical significance between groups was determined using the log-rank test. Results: We identified a cohort of 15 patients who initially refused treatment and 47 matched controls. The control cohort was well-matched, with no statistically significant differences in baseline characteristics (age, sex, Ann Arbor stage, B symptoms, International Prognostic Score (IPS) score, ECOG PS, and disease bulk) between groups. The most common reason for initial treatment refusal was to pursue alternative therapy (73%). 13 of 15 refusers eventually accepted treatment (mean time to treatment 76 weeks [range 26-214] vs. 5 weeks [range 1-8] for controls, p < 0.001). At time of treatment, the proportion of refusers with advanced-stage disease increased from 20% to 62% (p = 0.03) and had an associated alteration of treatment plan, and 62% of patients developed higher risk disease with increased IPS score (p = 0.02). At median follow-up of 5 years (0.4-21 years) for all living patients, estimated 5-year PFS was 65% vs 84%, and 5-year OS was 93% vs 98% for refusers and controls respectively. With extended follow up, 13% of refusers (1 late death at 8 years) compared to only 4% of controls died of cHL specifically. Conclusions: This study highlights the impact of treatment refusal in this highly curable malignancy. Initial refusal of treatment is associated with progression of stage, worsening prognostic score, escalation to more prolonged treatment than required at diagnosis, and increased risk of death from cHL. This analysis may help to provide guidance to counselling physicians, as well as inform patients who may be considering alternatives to standard of care for cHL.

Abstract
2640 Background: Endocrine immune-related adverse events (irAEs) are frequent with immune checkpoint inhibitors (ICIs); however, ICI-related insulin-dependent diabetes mellitus (IDDM) is a rare but serious endocrine irAE. We describe the characteristics of patients who developed ICI-related IDDM across five academic Canadian cancer centres. Methods: In this multicentre, retrospective study, we included both patients who developed IDDM and patients with non-IDDM (NIDDM) or pre-DM who became insulin-dependent while on treatment with ICI. We collected data on primary tumor type, ICI regimen (single agent or combination), time to development of IDDM from ICI initiation, comorbidities, laboratory parameters at the time of IDDM diagnosis, tumor response and survival. A p value < 0.05 was considered statistically significant. Results: We identified 27 patients between July 2016 and August 2019. Median age was 60 (39-79) years, 20 (74%) were male, 15 (55%) had melanoma and 4 each (15%) non-small cell lung cancer (NSCLC) and renal cell carcinoma. Seven (26%) patients had prior NIDDM or pre-DM; 5 (18%) had an auto-immune disease (2 psoriasis, 2 inflammatory bowel disease, and 1 systemic lupus erythematosus). Laboratory parameters at presentation and management of IDDM are presented in the Table. Mean A1c was not statistically different between patients with or without prior NIDDM or pre-DM (8.4% vs. 8.6%; p = 0.9). All IDDM events were irreversible; 1 (4%) patient died of diabetic ketoacidosis. At time of IDDM diagnosis, 17 (63%) patients were receiving single agent anti-PD1 and 10 (37%) anti-PD1-based combinations (7 anti-CTLA-4, and 3 other compounds). Median time for development of IDDM from ICI initiation was 2.7 months (95% CI 0.2-5.3). Patients receiving combination ICI developed IDDM earlier than those treated with single agent (1.4 vs 4.8 months; p = 0.05). Amongst patients with metastatic disease (n = 24), 9 (38%) had a complete response and 7 (29%) had a partial response. Two patients (8%) were treated in the adjuvant setting; 1 (4%) received consolidation ICI. IDDM led to ICI discontinuation in 12 (44%) patients. After a median follow up of 21 months from ICI initiation, median survival was 30 months (95% CI NE) and was not reached in patients with melanoma and NSCLC. Conclusions: ICI-related IDDM is a rare and typically irreversible irAE that occurs early in the course of treatment and develops earlier with combination ICI. In this cohort, patients who developed ICI-related IDDM had a high tumor response rate and prolonged survival, especially melanoma and NSCLC patients. Prospective evaluation of autoantibodies to predict development of IDDM is ongoing.[Table: see text]

Abstract
PURPOSE The study objective is to describe and quantify the incidence of treatment-induced late effects in AYA lymphoma patients. METHODS Consecutive patients diagnosed with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) at 15-24 years of age were identified. All patients in British Columbia who received radiation therapy (RT) from 1974 to 2014 with ≥ 5-year survival post-RT were included. Late effects' analyses included only survivors who received RT to the relevant anatomical site(s) and/or relevant chemotherapy, and were reported as cumulative incidence (CI) ± standard error. RESULTS Three hundred and five patients were identified (74% HL). Median age of diagnosis was 21 years. Median follow-up was 19.1 years for secondary malignancy and 7.2 years for other endpoints. Hypothyroidism was the most prevalent late effect, with a CI of 22.4 ± 2.8% and 35.1 ± 4% at 5 and 10 years, respectively. CI of in-field secondary malignancy was 0.4 ± 0.4% at 10 years and 2.8 ± 1.2% at 20 years. CI of symptomatic pulmonary toxicity was 4.6 ± 1.5% and 6.8 ± 2.0% at 5 and 10 years, respectively, and was higher in patients receiving multiple RT courses (p = 0.009). Esophageal complications occurred at a CI of 1.4 ± 0.8% at 5 years and 2.2 ± 1.1% at 10 years. CI of xerostomia/dental decay was 2.6 ± 1.3% at 5 years and 4.9 ± 2.1% at 10 years. CI of cardiac disease was at 2.3 ± 0.9% at 5 years and 4.4 ± 1.5% at 10 years. CI of infertility was 6.5 ± 1.6% at 5 years and 9.4 ± 2.1% at 10 years. CONCLUSION Survivors of AYA lymphoma have a high incidence and diverse presentation of late effects. IMPLICATIONS FOR CANCER SURVIVORS AYA lymphoma survivors should be educated about their risks of late effects and offered screening and follow-up when appropriate.

Abstract
PURPOSE TTI-621 (SIRPα-IgG1 Fc) is a novel checkpoint inhibitor that activates antitumor activity by blocking the CD47 "don't eat me" signal. This first-in-human phase I study (NCT02663518) evaluated the safety and activity of TTI-621 in relapsed/refractory (R/R) hematologic malignancies. PATIENTS AND METHODS Patients with R/R lymphoma received escalating weekly intravenous TTI-621 to determine the maximum tolerated dose (MTD). During expansion, patients with various malignancies received weekly single-agent TTI-621 at the MTD; TTI-621 was combined with rituximab in patients with B-cell non-Hodgkin lymphoma (B-NHL) or with nivolumab in patients with Hodgkin lymphoma. The primary endpoint was the incidence/severity of adverse events (AEs). Secondary endpoint included overall response rate (ORR). RESULTS Overall, 164 patients received TTI-621: 18 in escalation and 146 in expansion (rituximab combination, n = 35 and nivolumab combination, n = 4). On the basis of transient grade 4 thrombocytopenia, the MTD was determined as 0.2 mg/kg; 0.1 mg/kg was evaluated in combination cohorts. AEs included infusion-related reactions, thrombocytopenia, chills, and fatigue. Thrombocytopenia (20%, grade ≥3) was reversible between doses and not associated with bleeding. Transient thrombocytopenia that determined the initial MTD may not have been dose limiting. The ORR for all patients was 13%. The ORR was 29% (2/7) for diffuse large B-cell lymphoma (DLBCL) and 25% (8/32) for T-cell NHL (T-NHL) with TTI-621 monotherapy and was 21% (5/24) for DLBCL with TTI-621 plus rituximab. Further dose optimization is ongoing. CONCLUSIONS TTI-621 was well-tolerated and demonstrated activity as monotherapy in patients with R/R B-NHL and T-NHL and combined with rituximab in patients with R/R B-NHL.

Abstract
PURPOSE The study objective was to assess the discussion of late effects (LEs) and screening recommendations (SRs) for adolescent and young adults (AYAs) treated for lymphoma. METHODS A retrospective study was conducted on AYA lymphoma survivors aged 15-24 years at diagnosis who received radiation therapy (RT) ± chemotherapy between 1984 and 2010 at any of the six British Columbia (BC) Cancer treatment centers across the province. Charts were reviewed to evaluate discussion of LEs and SRs. Susceptibility to specific LEs was determined by reviewing treatment details. RESULTS Of 305 patients, 212 (70%) had documented discussion of at least one specific LE, 39 (13%) had non-specific documentation only, and 54 (18%) had no documented discussion of LEs. Accounting only for patients susceptible to each LEs, the most frequently discussed LEs was radiation-induced (RI) neoplasm (42%), and the least frequently discussed LEs was carotid artery stenosis (0.4%). The most common SRs discussed in susceptible patients was for RI breast cancer (43%). Of patients discharged between 1985 and 1999 vs 2000 and 2014, LEs were discussed in 63 vs 93% (P < 0.0005), and SRs were discussed in 30 vs 65%, respectively (P < 0.0005). Older age at discharge, presence of a discharge note, and occurrence of a discharge appointment were associated with increased discussion of SRs. CONCLUSIONS Most survivors of AYA lymphoma received some discussion of LEs and SRs, but each relevant LEs and SRs was discussed in only a minority of susceptible patients. IMPLICATIONS FOR CANCER SURVIVORS Survivors of AYA lymphoma and their primary care professionals may not be appropriately informed of health risks and how to screen for them.

Abstract
Background The combination of nivolumab and ipilimumab is approved in several jurisdictions (United States, European Union, Canada) for the first-line treatment of patients with advanced melanoma. CheckMate 218 is a North American expanded-access program (eap) of nivolumab plus ipilimumab in patients with advanced melanoma. Here, we report safety and survival outcomes for the Canadian cohort in the eap. Methods Eligible patients were those 18 years of age or older with unresectable stage iii or iv melanoma, an Eastern Cooperative Oncology Group performance status of 0 or 1, and no prior anti-PD-1 or anti-ctla-4 therapy. Patients were treated with nivolumab 1 mg/kg and ipilimumab 3 mg/kg every 3 weeks for 4 cycles (induction phase); they then continued with nivolumab 3 mg/kg every 2 weeks (maintenance phase) until progression, unacceptable toxicity, or a maximum of 48 weeks, whichever occurred first. Safety and overall survival (os) data were collected. Results Of 194 patients enrolled, 174 were treated, and 51% continued on nivolumab maintenance. Median follow-up was 12.9 months. All-grade and grades 3-4 treatment-related adverse events were reported in 98% and 60% of patients respectively and led to treatment discontinuation in 40% and 28% of patients. Two treatment-related deaths were reported. The 12- and 18-month os rates were 80% [95% confidence interval (ci): 73% to 86%] and 76% (95% ci: 67% to 82%) respectively. Conclusions In this Canadian population, nivolumab plus ipilimumab demonstrated a safety profile and survival outcomes consistent with phase ii and iii clinical trial data.

Abstract
Gray zone lymphoma (GZL), a B-cell lymphoma with features intermediate between large B-cell lymphoma (LBCL) and classic Hodgkin lymphoma (cHL), is a rare and poorly defined entity. Alongside GZL, a subset of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) has been described with polymorphic/GZL-like morphology (polymorphic-EBV-L). To fill the important gap in our understanding of the pathogenic process underlying these entities, we performed a gene expression study of a large international cohort of GZL and polymorphic-EBV-L, combined with cHL and primary mediastinal large B-cell lymphoma (PMBCL) cases. In an unsupervised principal component analysis, GZL cases presented with intermediate scores in a spectrum between cHL and PMBCL, whereas polymorphic-EBV-L clustered distinctly. The main biological pathways underlying the GZL spectrum were related to cell cycle, reflecting tumor cell content, and extracellular matrix signatures related to the cellular tumor microenvironment. Differential expression analysis and phenotypic characterization of the tumor microenvironment highlighted the predominance of regulatory macrophages in GZL compared with cHL and PMBCL. Two distinct subtypes of GZL were distinguishable that were phenotypically reminiscent of PMBCL and DLBCL, and we observed an association of PMBCL-type GZL with clinical presentation in the "thymic" anatomic niche. In summary, gene expression profiling (GEP) enabled us to add precision to the GZL spectrum, describe the biological distinction compared with polymorphic-EBV-L, and distinguish cases with and without thymic involvement as 2 subgroups of GZL, namely PMBCL-like and DLBCL-like GZL.

Abstract
8031 Background: Outcomes in elderly patients (pts) with Hodgkin lymphoma (HL) have traditionally been poor. We evaluated the survival of elderly pts (>60 years [y]) with classical HL in British Columbia (BC). Methods: All pts aged >60 y newly diagnosed with classical HL from 1961 to 2019 were identified in the BC Cancer Lymphoid Cancer Database. Limited stage was defined as non-bulky (<10 cm) stage 1A/IB or 2A (before 2000 1B = advanced stage), with the remainder considered advanced stage. Results: Following exclusions (HIV positive n=4, incomplete data n=21, prior or concurrent other lymphoproliferative disease n=67), 713 pts were identified. With a median follow up of 6.0 y (0.1 - 24.0 y) in living pts, there has been an improvement in 5 y DSS/OS (both p<.001) by decade comparison: 1960s (n=52) 25%/17%; 1970s (n=75) 38%/31%; 1980s (n=90) 51%/43%; 1990s (n=115) 53%/42%; 2000s (n=180) 66%/57%; 2010s (n=201) 63%/53%. To account for advances in diagnosis, staging, supportive care, and therapy in the modern era, we evaluated the outcome of pts diagnosed since 01/1995. A total of 368 pts were treated with curative intent (Table). Most pts received multi-agent chemotherapy (n=359, 98%: ABVD[like] n=351, alkylator-based n=7, CHOP n=1), 8 pts had radiotherapy (RT) alone, and 1 pt had surgery (primary CNS HL). The 5 y DSS, PFS, and OS were 74%, 57%, and 62%, respectively. Increasing age was associated with inferior outcomes (5 y DSS/PFS/OS): 61-70 y (81%/70%/74%), 71-80 y (69%/47%/52%), and >80 y (59%/27%/31%) (DSS p=.011; PFS p<.0001; OS p<.0001). Of 318 pts that received bleomycin, 60 (19%) developed pulmonary toxicity, including 22 cases that occurred after cycles 1 and 2. Overall, 24/368 pts (7%) died of acute treatment toxicity (pulmonary [bleomycin n=10, radiation n=1], infection n=10, cardiac n=3). There was no association between age and developing bleomycin (p=.80) or lethal treatment toxicities (p=.74). Conclusions: The outcome of elderly pts with HL has improved in recent decades. However, treatment related toxicity remains a concern and use of multi-agent chemotherapy, particularly bleomycin-containing regimens, should be undertaken with caution. [Table: see text]

Abstract
Hodgkin lymphoma is characterized by an extensively dominant tumor microenvironment (TME) composed of different types of noncancerous immune cells with rare malignant cells. Characterization of the cellular components and their spatial relationship is crucial to understanding cross-talk and therapeutic targeting in the TME. We performed single-cell RNA sequencing of more than 127,000 cells from 22 Hodgkin lymphoma tissue specimens and 5 reactive lymph nodes, profiling for the first time the phenotype of the Hodgkin lymphoma-specific immune microenvironment at single-cell resolution. Single-cell expression profiling identified a novel Hodgkin lymphoma-associated subset of T cells with prominent expression of the inhibitory receptor LAG3, and functional analyses established this LAG3+ T-cell population as a mediator of immunosuppression. Multiplexed spatial assessment of immune cells in the microenvironment also revealed increased LAG3+ T cells in the direct vicinity of MHC class II-deficient tumor cells. Our findings provide novel insights into TME biology and suggest new approaches to immune-checkpoint targeting in Hodgkin lymphoma. SIGNIFICANCE: We provide detailed functional and spatial characteristics of immune cells in classic Hodgkin lymphoma at single-cell resolution. Specifically, we identified a regulatory T-cell-like immunosuppressive subset of LAG3+ T cells contributing to the immune-escape phenotype. Our insights aid in the development of novel biomarkers and combination treatment strategies targeting immune checkpoints.See related commentary by Fisher and Oh, p. 342.This article is highlighted in the In This Issue feature, p. 327.

Abstract
Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of mature T-cell malignancies; approximately one-third of cases are designated as PTCL-not otherwise specified (PTCL-NOS). Using gene-expression profiling (GEP), we have previously defined 2 major molecular subtypes of PTCL-NOS, PTCL-GATA3 and PTCL-TBX21, which have distinct biological differences in oncogenic pathways and prognosis. In the current study, we generated an immunohistochemistry (IHC) algorithm to identify the 2 subtypes in paraffin tissue using antibodies to key transcriptional factors (GATA3 and TBX21) and their target proteins (CCR4 and CXCR3). In a training cohort of 49 cases of PTCL-NOS with corresponding GEP data, the 2 subtypes identified by the IHC algorithm matched the GEP results with high sensitivity (85%) and showed a significant difference in overall survival (OS) (P = .03). The IHC algorithm classification showed high interobserver reproducibility among pathologists and was validated in a second PTCL-NOS cohort (n = 124), where a significant difference in OS between the PTCL-GATA3 and PTCL-TBX21 subtypes was confirmed (P = .003). In multivariate analysis, a high International Prognostic Index score (3-5) and the PTCL-GATA3 subtype identified by IHC were independent adverse predictors of OS (P = .0015). Additionally, the 2 IHC-defined subtypes were significantly associated with distinct morphological features (P < .001), and there was a significant enrichment of an activated CD8+ cytotoxic phenotype in the PTCL-TBX21 subtype (P = .03). The IHC algorithm will aid in identifying the 2 subtypes in clinical practice, which will aid the future clinical management of patients and facilitate risk stratification in clinical trials.

Abstract
A novel prognostic score (IPS-3), comprised of only three of the seven IPS-7 indicators (age ≥45, stage IV, haemoglobin <105 g/l), was recently proposed as a simplified model for advanced-stage classic Hodgkin lymphoma (cHL). We aimed to validate this model in advanced-stage cHL patients treated with doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) in British Columbia. The estimated five-year freedom from progression (FFP) for scores of 0, 1, 2 and 3 were very similar to the original report at 84%, 76%, 72% and 68% respectively. The IPS-3 score is highly reproducible in this independent dataset and its simplicity makes it appealing for everyday clinical practice.

Abstract
Importance This analysis provides long-term follow-up in patients with BRAF wild-type advanced melanoma receiving first-line therapy based on anti-programmed cell death 1 receptor inhibitors. Objective To compare the 3-year survival with nivolumab vs that with dacarbazine in patients with previously untreated BRAF wild-type advanced melanoma. Design, Setting, and Participants This follow-up of a randomized phase 3 trial analyzed 3-year overall survival data from the randomized, controlled, double-blind CheckMate 066 phase 3 clinical trial. For this ongoing, multicenter academic institution trial, patients were enrolled from January 2013 through February 2014. Eligible patients were 18 years or older with confirmed unresectable previously untreated stage III or IV melanoma and an Eastern Cooperative Oncology Group performance status of 0 or 1 but without a BRAF mutation. Interventions Patients were treated until progression or unacceptable toxic events with nivolumab (3 mg/kg every 2 weeks plus dacarbazine-matched placebo every 3 weeks) or dacarbazine (1000 mg/m2 every 3 weeks plus nivolumab-matched placebo every 2 weeks). Main Outcome and Measure Overall survival. Results At minimum follow-ups of 38.4 months among 210 participants in the nivolumab group (median age, 64 years [range, 18-86 years]; 57.6% male) and 38.5 months among 208 participants in the dacarbazine group (median age, 66 years [range, 25-87 years]; 60.1% male), 3-year overall survival rates were 51.2% (95% CI, 44.1%-57.9%) and 21.6% (95% CI, 16.1%-27.6%), respectively. The median overall survival was 37.5 months (95% CI, 25.5 months-not reached) in the nivolumab group and 11.2 months (95% CI, 9.6-13.0 months) in the dacarbazine group (hazard ratio, 0.46; 95% CI, 0.36-0.59; P < .001). Complete and partial responses, respectively, were reported for 19.0% (40 of 210) and 23.8% (50 of 210) of patients in the nivolumab group compared with 1.4% (3 of 208) and 13.0% (27 of 208) of patients in the dacarbazine group. Additional analyses were performed on outcomes with subsequent therapies. Treatment-related grade 3/4 adverse events occurred in 15.0% (31 of 206) of nivolumab-treated patients and in 17.6% (36 of 205) of dacarbazine-treated patients. There were no deaths due to study drug toxic effects. Conclusions and Relevance Nivolumab led to improved 3-year overall survival vs dacarbazine in patients with previously untreated BRAF wild-type advanced melanoma.

Abstract
Management practices in early-stage (I/II) follicular lymphoma (FL) are variable and include radiation (RT), systemic therapy, or combined modality therapy (CMT). There is a paucity of data regarding maintenance rituximab in this cohort. We conducted an international retrospective study of patients with newly diagnosed early-stage FL staged with positron emission tomography (PET)-computed tomography and bone marrow biopsy. Three hundred sixty-five patients (stage I, n = 221), median age 63 years, treated from 2005-2017 were included, with a median follow-up of 45 months. Management included watchful waiting (WW; n = 85) and active treatment (n = 280). The latter consisted of RT alone (n = 171) or systemic therapy (immunochemotherapy [n = 63] or CMT [n = 46]). Forty-nine systemically treated patients received maintenance rituximab; 72.7% of stage I patients received RT alone, compared to 42.6% with stage II (P < .001). Active therapies yielded comparable overall response rates (P = .87). RT alone and systemic therapy without maintenance rituximab yielded similar progression-free survival (PFS) (hazard ratio [HR], 1.32; 95% confidence interval [CI], 0.77-2.34; P = .96). Maintenance rituximab improved PFS (HR, 0.24; 95% CI, 0.095-0.64; P = .017). The incidence of transformation was lower with systemic therapy compared to RT or WW (HR, 0.20; 95% CI, 0.070-0.61; P = .034). Overall survival was similar among all practices, including WW (P = .40). In the largest comparative assessment of management practices in the modern era, variable practices each resulted in similar excellent outcomes. Randomized studies are required to determine the optimal treatment in early-stage FL.

Abstract
Abstract
Aberrant activation of the JAK-STAT pathway is a hallmark of a variety of lymphomas and can alter the lymphoma cells secretome and the composition of the tumor microenvironment (TME). The up-regulation of the immune regulatory chemokine CCL17 has been shown to be mediated by STATs-dependent mechanism in primary mediastinal B cell lymphoma (PMBCL). Here, we assembled a cohort of 340 R-CHOP-treated aggressive lymphomas with diffuse large B cell lymphoma (DLBCL) morphology to investigate JAK-STAT mutations (targeted gene sequencing), copy number (CN) alterations (SNP arrays), gene expression (RNAseq) and TME composition (IHC). The cohort was evaluated using FISH for BCL2, BCL6 and MYC rearrangements and the molecular classification assay, Lymph2Cx, to distinguish ABC vs GBC vs double-hit lymphomas with DLBCL morphology (DH-DLBCL). Among the 317 evaluable cases, 26 were DH-DLBCLs, 101 ABC, 155 GCB and 35 unclassified. In addition, we used the recently published Lymph3Cx assay (Mottok A. et al., Blood 2018) to identify cases with a molecular PMBCL (mPMBCL) expression signature within the GCB-DLBCL group (6.5%, 10/155 cases). Twenty-five of 155 GCB cases (16.1%) were classified as ‘uncertain PMBCL/DLBCL’. Mutational analysis of all cases (n=340) revealed the presence of JAK-STAT pathway mutations at the following frequencies: SOCS1 21.6%, STAT6 4.8%, IL4R 5.3% and 9p24 amplification 11.3%. These mutations were significantly enriched in the mPMBCL (n=10) group compared to the bona fide GCB (n=118) and intermediate phenotype group (uncertain PMBCL/DLBCL) (n=25) (p<0.05). The relative frequency of any JAK-STAT mutations was 100% (10/10) in mPMBCL, 29.2% (35/118) in bona fide GCB and 56% (14/25) in uncertain PMBCL/DLBCL. Among the GCB samples with follow-up data (n=107, incl. bona fide GCB and mPMBCL), cases carrying mutations in IL4R (n=11, 10.3%) had an inferior disease-specific survival (p=0.011) and time to progression (p=0.0048) after R-CHOP therapy. Interestingly, IL4R mutations were also detected in the DH-DLBCL group with an incidence of 11.5% (3/26 cases). Mutations in the extracellular and transmembrane domains of IL4R resulted in gain-of-function mutations leading to constitutive activation of the JAK-STAT pathway in vitro. IL4R gain-of-function increased CCL17 expression through a STAT6-dependent mechanism in vitro. Similarly, gene expression analysis of primary patient samples carrying activating IL4R mutations displayed increased CCL17expression (p<0.05), which positively correlated with the level of the T-regulatory marker FOXP3 (p<0.05) by IHC. In summary, aberrant JAK-STAT activation driven by alterations, such as activating IL4R mutations, plays a significant role in altering chemokine expression profiles and TME changes. Our data strongly suggest the biological and clinical relevance of Lymph3Cx to define a subgroup of aggressive lymphoma harboring a molecular PMBCL signature.

Abstract
PURPOSE Nivolumab, an anti-programmed death-1 monoclonal antibody, has demonstrated frequent and durable responses in relapsed/refractory classic Hodgkin lymphoma (cHL). We report results from Cohort D of the CheckMate 205 trial, which assessed nivolumab monotherapy followed by nivolumab plus doxorubicin, vinblastine, and dacarbazine (N-AVD) for newly diagnosed cHL. METHODS Patients 18 years of age or older with untreated, advanced-stage (defined as III to IV and IIB with unfavorable risk factors) cHL were eligible for Cohort D of this multicenter, noncomparative, phase II trial. Patients received nivolumab monotherapy for four doses, followed by 12 doses of N-AVD; all doses were every 2 weeks, and nivolumab was administered at 240 mg intravenously. The primary end point was safety. Efficacy end points included objective response rate and modified progression-free survival, defined as time to disease progression/relapse, death, or next therapy. Chromosome 9p24.1 alterations and programmed death-ligand 1 expression were assessed in Hodgkin Reed-Sternberg cells in evaluable patients. RESULTS A total of 51 patients were enrolled and treated. At diagnosis, 49% of patients had an International Prognostic Score of 3 or greater. Overall, 59% experienced a grade 3 to 4 treatment-related adverse event. Treatment-related febrile neutropenia was reported in 10% of patients. Endocrine immune-mediated adverse events were all grade 1 to 2 and did not require high-dose corticosteroids; all nonendocrine immune-mediated adverse events resolved (most commonly, rash; 5.9%). At the end of therapy, the objective response rate (95% CI) per independent radiology review committee was 84% (71% to 93%), with 67% (52% to 79%), achieving complete remission (five patients [10%] were nonevaluable and counted as nonresponders). With a minimum follow-up of 9.4 months, 9-month modified progression-free survival was 92%. Patients with higher-level Hodgkin Reed-Sternberg programmed death-ligand 1 expression had more favorable responses to N-AVD (P = .041). CONCLUSION Nivolumab followed by N-AVD was associated with promising efficacy and safety profiles for newly diagnosed, advanced-stage cHL.

Abstract
7532 Background: The phase 3 ECHELON-1 study demonstrated that BV with AVD (A+AVD) was superior to ABVD for the frontline treatment of Stage 3/4 cHL. Maturing data from RATHL and SWOG S0816 show limitations to PET2-adapted strategies, including short and long-term toxicities in PET2+ patients (pts) switched to BEACOPP and still frequent relapse in PET2- pts. Pts in the RATHL trial with Stage 3/4 disease ≤60 yrs had a 3-yr PFS of 79.8% (82.1% PET2-); SWOG S0816 reported a 5-yr PFS of 74% (76% PET2-) in the same population. As an alternative to PET-adapted therapy, here we present a 3-year update of the ECHELON-1 study, including ITT PFS and outcomes by PET status. Methods: Pts with Stage 3/4 cHL were randomized 1:1 to receive up to six cycles of A+AVD (n=664) or ABVD (n=670). Interim PET scan after cycle 2 was conducted. All analyses of PFS are exploratory and per investigator assessment. Results: At a median follow-up of 37 months, analysis of PFS in the ITT population favors the A+AVD treatment arm (Table), with a 3-yr PFS of 83.1% for A+AVD vs 76.0% for ABVD; the 3-yr PFS for PET2- pts <60 yrs was 87.2% vs 81.0%, respectively. Trend toward benefit for PET2+ pts <60 yrs treated with A+AVD was also observed, with a 3-yr PFS of 69.2% vs 54.7% with ABVD. Data from prespecified subgroups and safety follow-up, including peripheral neuropathy, will be presented. Conclusions: Follow-up at 3-yrs demonstrates that frontline treatment of Stage 3/4 cHL with A+AVD provides a durable treatment benefit vs ABVD that is independent of PET2 status. While direct comparisons cannot be made, A+AVD compares favorably to PET-adapted strategies without requiring interim PET assessment, escalation of therapy, or bleomycin. Clinical trial information: NCT01712490. [Table: see text]
