e19516 Background: Anthracycline based chemotherapy is the treatment of choice for aggressive primary lymphomas of the GI tract, with surgery reserved for management of complications. We report long term follow up of 71 cases of primary GI NHL treated with chemotherapy and/or surgery. Methods: Cases were identified from the institutional histology database & records reviewed. Results: 71 patients over an 24 year period were identified; 43 (61%) male, 28 (39%) female. Median age at diagnosis was 60 (15–83). 52 (73%) were DLBCL, 11 (16%) were T-cell, 8 (11%) were MALT. The 8 patients with MALT were treated with single agent chemotherapy; 7 (88%) are alive at median follow up of 8.5 years (2–16). Of the aggressive lymphomas (63), all patients with T cell lymphoma had small bowel as primary site and histological evidence of celiac associated enteropathy, even in the absence of known celiac disease. Primary sites of DLBCL were stomach 35 (67%), small bowel 11 (21%) & colon 6 (12%). 39 (62%) patients underwent surgery at diagnosis due to acute presentation with perforation, bleeding or obstruction, or to obtain histology. Following confirmed diagnosis, 61 patients received anthracycline based chemotherapy. 2 patients with T cell lymphoma presented with perforation, were treated with surgery only and died of rapid disease progression. Of the 63 patients with aggressive NHL, 37 (59%) remain alive & disease free at median follow up of 13 years (1–24). 35 (67%) patients with DLBCL are alive & disease free. Only 2 (18%) of the T cell lymphomas are alive & disease free. 5 deaths in the DLBCL group were not related to cancer or treatment. All deaths in the T cell group were due to progressive disease. There was no difference in survival between patients treated with chemotherapy only and those who also underwent surgery. Conclusions: Patients with aggressive primary B cell GI NHL have almost 70 % survival following anthracycline based chemotherapy. However, in contrast, coeliac enteropathy associated T-cell lymphomas present with rapidly progressive disease & have a survival of < 20% with chemotherapy and/or surgery. A novel therapeutic approach is required to improve outcome in this group. No significant financial relationships to disclose.

Long Term Follow Up

Background: Mature T cell and NK cell neoplasms collectively known as peripheral T-cell lymphomas (PTCL) comprise 15-20% of Non-Hodgkin lymphomas in adults and have a poor prognosis with a 5-year survival of less than 30% for the most aggressive subtypes. Allogeneic HCT (allo-HCT) is offered to eligible patients as a potentially curative modality in the salvage setting or in high risk patients to consolidate an initial response to frontline therapy. There are few studies that report clinical outcomes derived from large sample size and long-term follow up data. Methods: We retrospectively reviewed medical records of 87 consecutive patients with PTCL including transformed mycosis fungoides and NK/T-cell lymphoma without prior autologous transplant who underwent allo-HCT at City of Hope from January 2000 to June 2018 after IRB approval was obtained. Descriptive statistics were used to summarize baseline patient demographic, treatment, and disease characteristics. Kaplan-Meier curves and the log-rank test were used to evaluate the overall survival (OS) and progression-free survival (PFS). Cumulative incidences of time to relapse and time to non-relapse mortality (NRM) were calculated with relapse and NRM as competing risks. Cumulative incidences of acute and chronic GVHD were calculated as time to onset of GVHD with relapse and death as competing events for GVHD. Results: 87 patients were included for the analysis. Median age at the time of allo-HCT was 49 years (range 2-70 years). Histologies were PTCL-NOS (n=21); transformed CTCL (n=19); NK T-cell lymphoma (n=17); AITL (n=15), ALCL (n=7); gamma delta T-cell lymphoma (n=6) and other rare subtypes (n=2). None of the patients had a prior auto transplant. 42 patients (48%) received myeloablative conditioning, with the majority of patients receiving FTBI based conditioning (n=39) and three patients received BEAM regimen for conditioning. 45 patients (52%) received reduced intensity conditioning; fludarabine/melphalan based-conditioning was the most common regimen used (n=39). Sibling HCT was performed in 47 patients (54%), while MUD HCT was performed in 36 patients (41%) with fully matched HLA unrelated donor in 15 (17%) and HLA mismatched in 21 (24%) patients; 4 (5%) received haploidentical HCT. GVHD prophylaxis consisted of tacrolimus/sirolimus (n=54), tacrolimus/sirolimus/MTX (n=11), tacrolimus or cyclosporine/MTX (n=7), tacrolimus or cyclosporine/MMF (n=7), post-transplant cyclophosphamide/tacrolimus/MMF (n=5) and other (n=3). Source of stem cells was PBSC in 77 (88%), bone marrow in 5 (6%), and cord blood in 5 (6%) patients. At the time of allo-HCT, there were a total of 25 (29%) patients in complete remission (CR1 n=15, CR2+ n=10), 25 (29%) patients in partial remission 22 (25%) with induction failure and 14 (16%) with relapsed disease. The median follow-up among survivors was 6.9 years (range 1.1-15.5). The 5- and 10-year PFS was 47% (95% CI: 36%-58%) and 38% (95% CI: 26%-50%), respectively. The 5- and 10-year OS was 53% (95% CI: 41%-63%) and 42% (95% CI: 29%-54%), respectively (Fig.1). Relapses at 5 and 10 years were both 24% (95% CI: 16%-34%), while NRM at 5 and 10 years was 28% (95% CI: 19%-39%) and 37% (95% CI: 25%-50%), respectively. At day 100 after allo-HCT, the rates of acute GVHD grade II-IV were 41% (95% CI: 30%-51%) and grade III-IV of 16% (95%CI: 9%-25%). Chronic GVHD rates at 3 years were 62% (95% CI: 51%-72%), with extensive GVHD of 55% (95% CI: 44%-65%). On univariate analysis, age (> 60 or not), sex, TBI-based conditioning, donor type (MSD vs MUD), stem cell source or remission status prior to allo-HCT did not predict for overall survival in our study. Conclusions: Our results constitute the largest reported single-institution series with a long-term follow-up on allo-HCT outcomes in patients with aggressive T-cell NHL. The 5-year PFS and OS of 47 and 53%, respectively, are encouraging for the high-risk T-cell NHL patients with limited treatment options.

8524 Background: Improved therapy is needed for patients (pts) with early-stage non-small cell lung cancer (NSCLC), as the majority relapse after curative resection. Our group reported the first trial of neoadjuvant PD-1 blockade in resectable NSCLC, finding therapy to be safe and feasible. Here we report extended clinical follow-up and long-term molecular response data from this trial. Methods: IV nivolumab 3 mg/kg was given every 2 weeks for 2 doses prior to surgery in 20 pts with resectable NSCLC at Johns Hopkins and MSKCC. Blood for correlative studies was taken prior to each dose of nivolumab, prior to surgery, 2-4 weeks post-surgery, and during long-term follow up. In a subgroup of pts, longitudinal molecular data was assessed in peripheral blood for circulating tumor DNA (ctDNA) and dynamics of tumor-infiltrating T-cell clonotypes. Results: At median follow up of 30 months (m), 15 of 20 pts are disease-free and alive. Two pts have died (one from relapsed disease). Median recurrence free survival (RFS) has not been reached. The 24m RFS rate is 69% (95% CI: 51-93). Thus far, presence of ctDNA at diagnosis and major pathologic response (MPR - ≤10% viable tumor in resected specimen) do not associate with RFS. One long-term immune-related adverse event has occurred (skin, G3). All pts who on pathologic review had ≥30% reduction in viable tumor in response to nivolumab demonstrated clearance of detectable ctDNA from blood prior to surgery. Pts with MPR experienced expansion of neoantigen-specific T-cells in peripheral blood. In one patient with ongoing disease free status, expansion of tumor-associated T-cells has persisted in peripheral blood beyond 15m from surgery. By contrast, in a patient who had detectable peri-operative ctDNA and 75% residual disease at surgery, minimal T-cell expansion was observed in peripheral blood, with a decreasing frequency of expanded T-cell clones over time that correlated with eventual cancer relapse. Conclusions: Long-term follow up reinforces the safety of neoadjuvant nivolumab in resectable NSCLC. Analysis of ctDNA and peripheral T-cell expansion in responders compared with non-responders suggests potential biomarkers for response and surveillance. While RFS data is encouraging, phase 3 trials are ongoing to evaluate efficacy of PD-(L)1 blockade in early-stage NSCLC. Clinical trial information: NCT02259621.

Abstract Peripheral T-cell lymphomas (PTCL) represent a heterogeneous group of non-Hodgkin’s lymphomas, which in general show a poor outcome following conventional chemotherapy. Long-term remissions are achieved in only 15 to 35 %. However, the impact of more aggressive therapeutic approaches such as myeloablative therapy with autologous stem cell transplantation (ASCT) as first line therapy is poorly defined mainly due to the lack of prospective PTCL-restricted studies. In 6/00 we initiated the first prospective PTCL-restricted multicenter study of myeloablative radiochemotherapy in primary diagnosed PTCL. The results of the first 30 patients (pts) are in press. We update our data on all pts entering the study. Study design: Pts < 65 years with PTCL of all subtypes without primary cutaneous lymphoma and ALK1 expressing anaplastic large cell lymphoma were included. Treatment consisted of 4–6 courses of CHOP protocol followed by DexaBEAM or ESHAP regimen and collection of stem cells. Subsequently pts underwent total body irradiation (TBI) and high dose cyclophosphamide chemotherapy (60 mg/kg body weight) with ASCT. Patient characteristics: From 6/00 to 8/04 65 pts (42 male) with a median age of 50 years were enrolled. Main subtypes were Peripheral T-cell lymphoma not otherwise specified (NOS, n= 26) and Angioimmunioblastic T-cell lymphoma (AILT, n= 19). According to the Ann Arbor classification, 81% of the pts had stage III/IV disease. The International Prognostic Index (IPI) was low/low intermediate in 54% and intermediate high/high in 46% of the pts, respectively. Results: So far 54 of 65 pts are eligible for evaluation, while the remaining 11 pts are still under therapy. Thirty-three pts could be transplanted (61%). After a median follow up of 10 months after transplantation 22 pts (67%) are in sustained remission and 8 pts (27%) had relapsed. Post transplantation two pts died treatment-related (one secondary AML, one multiorgan failure). Twenty-one pts (39%) did not proceed to ASCT mainly due to progressive disease (n= 16). Treatment-related toxicity was comparable to other high-dose studies in malignant lymphomas. Conclusion: Our data show feasibility and efficacy of first-line ASCT following myeloablative radiochemotherapy in PTCL. Sustaining remission seems achievable for a majority of pts. However, additional treatment strategies are required to prevent early progression prior myeloablative therapy. Longer follow-up is necessary to confirm long-term remission rate.

Indolent T-cell lymphoproliferative disorder (T-LPD) of the gastrointestinal (GI) tract is a new provisional entity in the 2016 revision of the World Health Organization classification. The disease has an indolent course and progression to aggressive T-cell lymphoma has rarely been reported. We describe a case of a 37-year-old male with indolent T-LPD of the GI tract who 3 years later developed aggressive T-cell lymphoma and died of progressive disease. An infiltrate of indolent T-LPD in the GI tract and aggressive lymphoma diagnosed from the liver biopsy had similar immunophenotype, but cellular infiltrate in the liver showed more atypia compared with the GI biopsies of indolent T-LPD. Moreover, T-cell gene rearrangement studies showed an identical clonal rearrangement in indolent T-LPD and aggressive lymphoma. Patients with indolent T-LPD of the GI tract need a long-term follow-up, as some of them may develop more aggressive lymphoma.
