Nivolumab Induces Remission in High- PD-L1 Expressing Aggressive B-Non Hodgkin Lymphoma: A Single Center Experience

Abstract Patients with relapsed or refractory aggressive B-cell Non-Hodgkin lymphoma (B-NHL) have a poor outcome. Nivolumab (NV) targeting the PD-1 receptor has shown promising results in several malignancies like melanoma, renal and lung carcinoma and Hodgkin lymphoma. Data for aggressive B-NHL are just emerging. PD-L1 expression does not necessarily correlate with response. Among lymphoma subtypes, the expression of PD-L1 seems to vary. So far there are no valid data on PD-L1 expression in aggressive lymphoma under NV treatment. We retrospectively analyzed seven patients who had aggressive B-NHL with a refractory or relapsed disease after at least 3 regimens and were thereupon treated with NV 3mg/kg once a fortnight. Treatment was initiated after signed informed consent for off-label use. The histologic specimens were analyzed for PD-L1 expression by immunohistochemistry (IHC). The median age at NV treatment start was 51 years (27-71). The histopathological diagnoses were primary mediastinal B-cell lymphoma (PMBL; n=2), composite lymphoma with diffuse large B-cell (DLBCL) and Hodgkin lymphoma components (n=2), follicular lymphoma transformed into a DLCBL (n=2) and one mediastinal grey zone lymphoma (MGZL). A median of 5 (3-7) prior therapy regimens were given including hematopoietic stem cell transplantation (HSCT) for 3 patients: autologous (n=2) and allogeneic HSCT (n=1), respectively. The lymphoma status was refractory in 2 patients and relapsed in 5 patients. PD-L1 expression was detected in 5 cases, 3 of them showing a positive staining of 10%, 30%, and 50%, respectively, and 2 cases even of 100% of the lymphoma cells. NV was mostly well tolerated (1 pneumonitis completely resolved after systemic steroid therapy, 1 unrelated death caused by septic shock) with a median of 3 (1-17) cycles administered. Response assessment (clinical examination, ultrasound, CT or PET-CT scans) were performed after a median of 3 cycles (2-7), showing regressive and refractory disease in 3 patients, respectively, while 1 patient died prior to response assessment. Among the three responders (2xCR, 1xPR) MGZL and PBML their tumors had high PD-L1 expression of 30% (n=1) and 100% (n=2), respectively. Two responders (one after autologous, one after allogeneic HSCT) are still under treatment. After 14 weeks, one responding patient showed signs of progression of a previously known cerebral lesion (or pseudo progression under immunotherapy). The third responder proceeded to allogeneic HSCT without relevant complications. The PD-L1 expression among the non-responders were 0% (n=2) with progressive disease being the cause of death and 10% (n=1) for the other who is currently receiving alternative therapy. In conclusion, NV induces remission in heavily pretreated, PD-L1 high expression aggressive B-NHL. The significance of these data are limited due to the small number of patients. Therefore, future results of current phase II trials (NCT02038933) will reveal the role of PD-1 blockade in aggressive B-NHL.

Abstract Introduction Relapsed or refractory pediatric B-cell non-Hodgkin lymphoma (B-NHL) has been reported to be extremely difficult to cure. We previously conducted a retrospective study of pediatric relapsed or refractory B-NHL in Japan between 1996 and 2004 and found that the four-year overall survival rate was only 20.5% (Fujita N. e al. PBC. 2008). Rituximab, a chimeric anti-CD20 monoclonal antibody, is expected to be effective in improving the prognosis of pediatric relapsed or refractory B-NHL and was approved for use in 2003 in Japan. Here, we retrospectively assessed the treatment and prognosis of pediatric relapsed or refractory pediatric B-NHL in the rituximab era in Japan. Methods We collected relapsed pediatric B-NHL cases from patients enrolled in our current study, JPLSG B-NHL03 study, which was the first nationwide multicenter trial for newly diagnosed pediatric B-NHL. We collected information on treatment and outcome after induction failure or relapse. Results In 33 patients enrolled this study, the median age at diagnosis was 9.7 years and male predominance was observed. Nine cases were pathologically subclassified initially as diffuse large B-cell lymphoma, 11 as Burkitt lymphoma, 11 as Burkitt Leukemia and two as others. According to initial Murphy staging, most cases were in the advanced stage. The most common site of relapse was abdomen (8 cases), followed by bone marrow (8 cases) and central nervous system (7 cases). Twenty-three cases relapsed in one site while 10 did so in multiple sites. Among them, 20 relapsed within six months after initial diagnosis. Among them, 28 patients received some rituximab combined treatment as salvage therapy. R-ICE (rituximab, ifosfamide, carboplatin and etoposide) regimen was the most popular and used in 22 patients as first-line salvage therapy. As a result, 22 patients (66.7%) achieved complete remission (CR) by some salvage therapy. 23 received hematopoietic stem cell transplantation (HSCT). Their 5-year overall survival rate was 48.5%, which was far more superior to both our previous study (Figure 1) and another on relapsed or refractory B-NHL in childhood. In risk factor analysis for survival, rituximab combined treatment and HSCT did not influence the outcome, but achievement of CR after salvage treatment resulted in significantly better survival (68.2% vs 9.1%, p=0.001). These results suggest that the advent of rituximab induced an improvement of CR rate for relapsed paediatric B-NHL, which resulted in an improvement of the survival rate. Conclusion In conclusion, the prognosis of the pediatric relapsed or refractory B-NHL in a Japanese cohort remained poor but is showing improvement in the rituximab era.

Primary Location

B-cell lymphoblastic lymphoma which is a type of non-Hodgkin lymphoma is rather uncommon in children. Focal changes in bones in the course of non-Hodgkin lymphoma are mostly secondary changes and their primal location in a bone is rare. PBL (primary bone lymphoma) mainly concerns a thighbone and a tibial bone; the primary location in jaw bones is quite sporadic. In diagnostics, there is mainly magnetic resonance, medical scan (tomography), and above all – histopathological test. There is also chemotherapy by choice, and primary location in a jaw or a mandible significantly advances the prognosis. The aim of the work is to introduce a patient who was definitively diagnosed B-cell lymphoblastic lymphoma from the early B-cells. The girl reported to Laryngological Clinic, Dental Surgery Clinic for Children, Oncological Clinic of Children’s Memorial Health Institute. The cause of the visit was an elevation on the right side of a nose base, present for two months and misdiagnosed by doctors as a post-traumatic swelling in this region. After introducing laboratory and scan diagnostics and taking biopsy from the lesion, a final conclusion was made. Also, a proper treatment according to the protocol for B-cell lymphoblastic lymphoma was introduced. Non-specific B-cell lymphoma picture, as mentioned in the described case, specifically due to location in a jaw bone and a slow pace of growing, may both constitute huge diagnostic problems and deteriorate prognosis. Therefore, it is important to take into account also lymphoma – in such location of a lesion. Moreover, it is worth remembering that the final diagnosis may only be passed on the basis of histopathological examination.

Indication For Treatment

Abstract Background: Frontline treatment of indolent B-cell non-Hodgkin lymphoma (iB-NHL) typically involves intravenously administered anti-CD20 monoclonal antibodies with or without cytotoxic chemotherapy. Effective and low-toxicity therapies with improved convenience of administration are sought. We hypothesized that ixazomib (Ix) could safely and conveniently induce remissions in patients with untreated iB-NHL. Here we present the first data on frontline use of Ix in untreated iB-NHL. Methods: This single-arm, open-label phase II "window" trial for patients with untreated iB-NHL (NCT02339922) opened to enrollment in May 2016. Eligibility included histopathologically confirmed iB-NHL, measurable disease, a clinical indication for treatment based on NCCN guidelines, and no prior systemic treatment. Ix was administered at 4 mg orally once a week on consecutive 28-day cycles until disease progression or unacceptable toxicity and four doses of weekly rituximab (R) were added during the 7th cycle, after the initial window period. The primary endpoint was investigator-assessed response rate after independent radiology review. Response assessment occurred at every 2 cycles and using standard (Lugano) criteria. Tumor tissue was collected for gene expression profiling and immunohistochemical evaluation of molecular pathways associated with proteasome inhibition. Results: As of July 1, 2018, 15 patients were treated. The median age was 64 years (range, 47 to 81) and 53% were men. Disease histologies included follicular lymphoma (FL, n = 10), mantle cell lymphoma (MCL, n = 2), marginal zone lymphoma (MZL, n = 2), and small lymphocytic lymphoma (SLL, n = 1). At the start of therapy, all had stage III/IV disease and B-symptoms were present in 40%. For patients with FL, 80% had poor risk by FLIPI. Overall, the indication for treatment included symptoms due to disease (40%), steady progression of disease (33%), and cytopenia due to disease (27%). To date, 14 patients were evaluable for response and 13 experienced tumor burden reduction during the Ix-only window (Figure 1). Of patients with FL, 6 completed the Ix-only window phase and, of these, 5 achieved PR. An additional 4 patients with FL have not completed all 6 cycles of Ix monotherapy. Of these, 1 patient achieved a PR after 4 cycles and continues on treatment, 1 patient came off study with stable disease after 4 cycles, and 2 patients have experienced tumor reduction without meeting formal response criteria and continue on treatment (after 2 and 4 cycles, respectively). Of those patients with FL that received R, all achieved formal remission (3 CR, 3 PR). Median progression free survival has not been reached with a median follow up of 7.4 months. No patient with non-FL histology had yet achieved a PR during the Ix-only window or had undergone response assessment after receiving R at the time of the data cut. The most common adverse events (AEs) for all pts were grade 1-2 and included nausea (53%), diarrhea (53%), rash (40%), and fatigue (33%). Peripheral neuropathy occurred in 20% patients (grade 2 in 7%). A single grade ≥ 3 AE occurred (syncope, grade 3). Conclusions: Data from this interim analysis suggest that Ix monotherapy is well tolerated and highly active in the frontline treatment of FL with all patients demonstrating tumor reduction to date and augmented responses following the addition of R. Non-FL histologies of B-NHL appear less responsive to Ix, but numbers are small. Accrual on study continues. Correlative analyses are underway to determine if Ix or Ix-R may represent a viable frontline option for some patients with iB-NHL. Figure 1. Waterfall plot of response.

Abstract Novel strategies, such as chemosensitization with targeted agents, that build on the success of standard immunochemotherapy show promise for the treatment of non-Hodgkin lymphoma (NHL). Here, we report a phase 1b study investigating dose escalation of the BCL2 inhibitor, venetoclax, in combination with rituximab or obinutuzumab and cyclophosphamide, doxorubicin, vincristine, and prednisone (R-/G-CHOP) chemotherapy in B-cell NHL. Objectives included safety assessment and determination of a recommended phase 2 dose (RP2D). Fifty-six patients were enrolled, most with follicular lymphoma (43%) or diffuse large B-cell lymphoma (DLBCL; 32%). Dose-limiting toxicities were reported in 3/14 patients at the first venetoclax dose (200 mg/d), after which dosing was changed from daily to 10 days per cycle and escalated to 800 mg. A further reduction to 5 days per cycle occurred at the 800-mg dose level in the G-CHOP arm. Cytopenias were predominant among grade 3/4 events and reported at a higher rate than expected, particularly in the G-CHOP arm; however, safety was manageable. Overall response rates were 87.5% (R-CHOP and G-CHOP combinations); complete response (CR) rates were 79.2% and 78.1%, respectively. Most double-expressor (BCL2+ and MYC+) DLBCL patients (87.5%; n = 7/8) achieved CR. Although the maximum tolerated dose was not reached, the RP2D for venetoclax with R-CHOP was established at 800 mg days 4 to 10 of cycle 1 and days 1 to 10 of cycles 2 to 8; higher doses were not explored, and this dosing schedule demonstrated an acceptable safety profile. This regimen is subsequently being evaluated in first-line DLBCL in the phase 2 portion of the study. This trial was registered at www.clinicaltrials.gov as #NCT02055820.

Abstract Non-Hodgkin lymphoma (NHL) consists of a heterogeneous group of tumors. Population-based data on the familial risk for specific histopathologic subtypes have not been established. Such data are useful for clinical counseling and for searching tumor subtypes sharing common genetic pathways. We used the Swedish Family-Cancer Database to calculate standardized incidence ratios (SIRs) for histopathology-specific subtypes of NHL in 4455 offspring with NHL whose parents or siblings were affected with different types of lymphoproliferative malignancies. A familial history of NHL significantly increased the risk for NHL (SIRparent = 1.8; SIRsibling = 1.9) and for diffuse large B-cell lymphoma (SIRparent = 2.3), follicular lymphoma (SIRsibling = 2.3), and B-cell lymphoma not otherwise specified (NOS) (SIRsibling = 3.4). For a parental history of histopathology-specific concordant cancer, the risks were significantly increased for diffuse large B-cell lymphoma (SIR = 11.8), follicular NHL (SIR = 6.1), plasma cell myeloma (SIR = 2.5), and chronic lymphocytic leukemia (SIR = 5.9). Familial clusters for NHL seemed stronger in females and in siblings. Our study provides the first quantification of the familial risks for NHL by histopathology. The present findings give evidence for a strong familial association of NHL, with little differences in the magnitude of risks for various histopathologic subtypes. The patterns of risks in parents and siblings support the hypothesis of an autosomal-dominant component for diffuse large B-cell NHL and a recessive one for follicular NHL. (Blood. 2005;106:668-672)

Abstract Introduction CHOP chemotherapy has been accepted as the standard treatment for patients with non-Hodgkin lymphoma (NHL), but in some histological or clinical subtypes the results are not satisfactory. We have shown the efficacy and safety of high-dose biweekly THP-COP with G-CSF support (HDBW-TCOP(G)) for NHL. In this regimen, we choose pirarubicin in stead of doxorubicin because it was proven high efficacy against NHL and the lower toxicity than doxorubicin. Recently, the combination of rituximab and standard CHOP has been shown to have a synergistic effect for NHL. We performed a phase II multicentric clinical study to assessed the feasibility and toxicity of the combination chemotherapy of rituximab and HDBW-TCOP(G) (HDBW-R-TCOP(G)) compared with those of HDBW-TCOP(G). Patients and methods Between August 1998 and December 2004, Forty-one Japanese patients with previously untreated NHL from whom informed consent was obtained were included in this study. Median age was 45 (range 19–63) years. There were 19 males and 22 females. According to WHO-classification diagnoses, histological subtypes included follicular lymphoma (FL) 15(37%); nodal marginal zone B-cell lymphoma (NMZBCL) 2(5%); mantle cell lymphoma (MCL) 3(7%); anaplastic large cell lymphoma (ALCL) 1(2%), diffuse large B-cell lymphoma (DLBCL) 18(44%); peripheral T-cell lymphoma (PTCL) 1(2%), angioimmunoblastic T-cell lymphoma (AILT) 1(2%). Of 41 patients, one patient was stage 1, stage 2, 11 stage 3 and 16 stage 4. International prognostic index (IPI) included L 6; LI 22; HI 7; H 6. HDBW-TCOP(G) consisted of pirarubicin 70 mg/m2 on day 1; cyclophosphamide 1000 mg/m2 on day 1; vincristine 1.4 mg/m2 on day 1; predonisolone 50 mg/m2 orally from day 1 to 5; lenograstim 2.0 μg/kg/day from day 3. Fifteen patients who enrolled after rituximab was approved in Japan received therapy combined HDBW-TCOP(G) with rituximab 375mg/ m2 on day -2 (HDBW-R-TCOP(G)). Six cycles were administered at intervals of two weeks. Results Of the 41 patients treated, 32 (78.0%) achieved a complete remission (CR) and nine (22.0%) achieved a partial remission (PR), for an overall response rate of 100%. After median follow-up of 36 months (range 2.9– 81.8), progression free survival (PFS) and overall survival (OS) were 68.2% and 97.5%, respectively. PFS was 90.9% for HDBW-R-TCOP(G), and 69.5% for HDBW-TCOP(G), but no significant differences was found among two regimen. There was no significant difference in the PFS and OS between aggressive and indolent histological subtypes. 76% of patients developed Grade4 leukopenia (according to NCI criteria) but no patients experienced febrile neutropenia. 15% of patients developed G4 anemia and 17% of patients G4 thrombocytopenia. Other adverse effects were minimal. Conclusion Both HDBW-TCOP(G) and HDBW-R-TCOP(G) are feasible for NHL with acceptable toxicity. The excellent result suggests they are effective for aggressive NHL patients with poor prognostic factors and advanced stage indolent NHL.

Abstract One hundred and nineteen children with non-Hodgkin lymphoma were treated between February 2003 and December 2006 in Beijing Children’s Hospital on BCH-2003-NHL protocol. The diagnosis was made by histopathology of the biopsied tissue and/or bone marrow, and disease was classified according to WHO-2001 pathologic classification. We applied modified LMB89 protocol to cases with B-cell lymphoma; modified BFM90-ALL protocol for lymphoblastic lymphoma and cutaneous T-cell/NK cell lymphoma; and modified BFM90-ALCL protocol for anaplastic large-cell lymphoma (ALCL). There were 50 cases (42%) of B cell lymphoma including 32 cases of Burkitt¡’s lymphoma, 10 cases of Burkitt-like lymphoma and 8 cases of diffuse large B cell lymphoma; 44 cases (37%) of lymphoblastic lymphoma; 19 cases (16%) of ALCL; and 6 cases (5%) of cutaneous T-cell/NK cell lymphoma. The 85 boys and 34 girls (ratio, 2.5:1) ranged in age from 2 to 15 years (median, 7.8 years) at diagnosis. B cell lymphoma typically presented as abdomen mass and acute abdomen; nasopharynx and tonsil were also common sites of involvement. Lymphoblastic lymphoma generally presented with mediastinal mass and bone marrow involvement. There was no typical presentation for ALCL. According to the St. Jude staging system, 19 cases had stage I–II, and 94 cases stage III–VI diseases (exclude 6 cases of cutaneous T-cell/NK cell lymphoma). Seven cases had CNS involvement and 25 cases involved bone marrow. The treatment duration was 2 to 8 months for B-cell lymphoma, 2.5 to 3 years for lymphoblastic lymphoma and 1 to 1.5 years for ALCL. The follow-up rate was 100% and median observation period was 23 months. The overall survival (OS) at 3 years was 90.7% and the 3-year event-free survival (EFS) estimate was 82.3%. For B-cell lymphoma, 3-year OS was 88.68% and 3-year EFS was 81.8%. For lymphoblastoma lymphoma, the rates were 89.3% and 69.4%, respectively. All cases of ALCL are alive with on undergoing treatment for relapse. Patients with ALCL achieved the best 3-year OS (100%) and had 3-year EFS of 94.2%. Grade 3 or 4 bone marrow suppression occurred in 97.5% of patients with B-cell lymphoma, 100% of those with lymphoblastic lymphoma and 89.5% of cases with ALCL. As of to date, 11 patients have died, the causes of death include infection (n=4), abandonment of therapy (n=6) and relapse (n=1). Univarate analysis showed that stage IV disease, failure to achieve complete remission after 3 months of treatment, and bulky mass are were associated with poor prognosis £all P values <0.05£©. In summary, we have achieved excellent treatment results using modified international protocols. Infection and financial problem remained the main reasons of treatment failure.

Abstract Abstract 4633 Background: Golgins are proteins of the Golgi complex. Several Golgins have been implicated in apoptosis. Expression of Golgin-84, a Golgin protein, is altered in apoptotic WEHI-231, a B-cell lymphoma line, suggesting that Golgin-84 may play a role in lymphoid tumorigenesis. Here, we aimed to determine the expression levels of Golgin-84 in human primary non-Hodgkin lymphomas and plasma cell myeloma. Design: Golgin-84 expression was investigated in non-Hodgkin lymphoma cell lines by using Western blot analysis and polyclonal antibodies. Using immunohistochemical stains, Western blotting analysis and Q-PCR, Golgin-84 expression was assessed in 5 reactive lymph nodes, 149 cases of primary non-Hodgkin lymphoma and 28 cases of primary plasma cell myeloma. Results: Immunohistochemical stains, Western blotting analysis and Q-PCR on 5 reactive lymph nodes demonstrated that Golgin-84 was expressed at low levels in lymphoid cells of germinal centers, mantle cells, marginal zones, and interfollicular areas. Golgin-84 was variably expressed in non-Hodgkin lymphoma cell lines tested, with the highest levels in cells from high-grade tumors (e.g. anaplastic large cell lymphoma; ALCL, Diffuse large B-cell lymphoma (DLBCL), ALCL and peripheral T-cell lymphoma unspecified (PTCL)) and the lowest levels in mantle cell lymphoma (MCL) cells. DLBCL, ALCL and PTCL frequently showed high expression of Golgin-84. Most lymphoplasmacytic lymphomas (LPL) and plasma cell myeloma (PCM) expressed high levels of Golgin-84. Expression levels of Golgin-84 were lower in MCL and low-grade B-cell non-Hodgkin lymphomas, including chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), follicular lymphoma (FL), and marginal zone lymphoma (MZL). Conclusions: Golgin-84 expression levels are low in lymphoid cells of normal lymph nodes. Most (>90%) cases of LPL and PCM, and at least half of cases of DLBCL, ALCL and PTCL express high levels of Golgin-84. These findings suggest that Golgin-84 may be involved in tumorigenesis or lymphoma progression, particularly in neoplasms with plasmacytic differentiation.

Abstract Background In the rituximab era, there are several studies that have reported the risk factors for central nervous system (CNS) involvement in non-Hodgkin lymphoma, but the same factors emerge, such as high international prognostic index (IPI) score, >1 extranodal site, elevated lactate dehydrogenase (LDH) level, poor performance status (PS), advanced stage, bone marrow involvement. Macrophages are an important component of the tumor microenvironment and the immune response to malignancy. Recently, elevated peripheral blood monocyte counts have been shown to be an independent marker associated with poor prognosis in patients with both non-Hodgkin and Hodgkin lymphoma. Patients and methods We reviewed data from a total of 1238 lymphoma patients(1185 non-Hodgkin lymphoma, 53 Hodgkin lymphoma) at our institution between February 2005 and May 2013. Of these, 42 patients (3.4%) developed CNS complications during the clinical course. Thirty patients out of these 42 (71.4%) were diagnosed with diffuse large B-cell lymphoma (DLBCL). Therefore, we focused on DLBCL. In this study, we retrospectively analyzed data from a total of 557 DLBCL patients, 30 patients (5.4%) who developed CNS involvement and 527 patients with DLBCL but without CNS involvement. This study was approved by the Institutional Review Board of the Cancer Institute Hospital of the Japanese Foundation for Cancer Research. The clinical features of all 557 DLBCL patients, including 30 patients with CNS involvement, are summarized in Table 1. CNS involvement was defined by the presence of at least one histologically confirmed CNS involvement; neuroimaging findings compatible with CNS involvement with lymphoma, in conjunction with consistent clinical presentation; and the absence of other clinically feasible diagnosis or positive cerebrospinal fluid (CSF) (lymphoma cells detected by cytology). The absolute monocyte counts (AMC) and monocyte ratio were derived from pre-treatment complete blood counts. Pathological studies Immunohistochemical analysis was carried out using mAbs against CD68 at our institution. Results The incidence of CNS involvement was 5.4%, 1.3% having CNS involvement at diagnosis with DLBCL. Intriguingly, absolute monocyte counts (AMC) ≥0.6 (×109/L) at diagnosis were significantly frequent in 30 DLBCL patients (p=0.0420) with CNS involvement, compared with in 527 DLBCL patients without CNS involvement. Furthermore, the monocyte ratio ≥8% in peripheral blood at diagnosis was significantly frequent in 30 DLBCL patients (p=0.0325) with CNS involvement, compared with in 527 DLBCL patients without CNS involvement. DLBCL patients with CNS involvement showed age ≤60 years, stage III-IV, IPI score ≥3, and PS ≥2, elevated soluble IL-2 receptor levels was significantly frequent, compared with in DLBCL patients without CNS involvement. Neither gender, elevated LDH level, white blood cell counts (WBC) differed significantly in the two groups. With regard to pathological immunohistochemistry, the numbers of CD68 positive cells in or around lymphoma samples did not differ in the 14 DLBCL patients with CNS involvement that we were able to analyze, compared with DLBCL patients without CNS involvement. CNS involvement free survival rate in DLBCL patients was significantly lower in AMC ≥0.6 (×109/L) and/or the monocyte ratio ≥8% (Log-rank test, P=0.0102) in peripheral blood at diagnosis, compared with in AMC less than 0.6 (×109/L) and the monocyte ratio less than 8%. Conclusions These results suggest that in DLBCL patients, AMC and monocyte ratios in peripheral blood at diagnosis are closely correlated with the risk of eventual CNS involvement. AMC and monocyte ratios in peripheral blood at diagnosis in DLBCL patients could be a useful prognostic marker for the risk of CNS involvement during the clinical course.
