ABSTRACT

The real-world data on short course of immune checkpoint inhibitor (ICI) use are sparse and merit exploration. A multicentric observational study on the safety and efficacy of ICI in oncology patients between August 2014 and October 2020 involves 1011 patients across 13 centers in India. The median age was 59 (min 16-max 98) years with male preponderance (77.9%). The predominant cohort received short-course ICI therapy; the median number of cycles was 5 (95% confidence interval [CI] 1-27), and the median duration of therapy was 3 (95% CI 0.5-13) months. ICIs were used commonly in the second and third line setting in our study (66.4%, n = 671). Objective response rate (complete or partial response) was documented in 254 (25.1%) of the patients, 202 (20.0%) had stable disease, and 374 (37.0%) had progressive disease. The clinical benefit rate was present in 456 (45.1%). Among the patients whom ICI was stopped (n = 906), the most common reason for cessation of ICI was disease progression (616, 68.0%) followed by logistic reasons like financial constraints (234, 25.82%). With a median follow-up of 14.1 (95% CI 12.9-15.3) months, there were 616 events of progression and 443 events of death, and the median progression free survival and overall survival were 6.4 (95% CI 5.5-7.3) and 13.6 (95% CI 11.6-15.7) months, respectively, in the overall cohort. Among the immune-related adverse events, autoimmune pneumonitis (29, 3.8%) and thyroiditis (24, 2.4%) were common. Real-world multicentric Indian data predominantly with short-course ICI therapy have comparable efficacy/safety to international literature with standard ICI therapy.

ABSTRACT

As haematologists, we always seek to follow standardised guidelines for practice and apply the best treatment within our means for our patients with blood diseases. However, treatment can never follow an exact recipe. Opinions differ as to the best approach; sometimes more than one treatment approach results in identical outcomes, or treatments differ only by the manner in which they fail. Furthermore, the haematologist is faced with constraints relating to the local economic environment. Patients too are not the same the world over. Early presentation is commoner in the developed world, as is the patient's understanding of the disease process. This in turn has an impact on the way patients are managed, the rigorousness of patient adhesion to the treatment schedule and the outcome. Here we take a look at the precursor B-cell acute lymphoblastic leukaemia in an adolescent in a range of different settings from low- to high income countries with widely differing challenges for diagnosis, therpy and follow-up. For these reasons, given the same starting conditions, patients will be treated differently according to the institute and the country they are in. Experts from around the world have been tasked to describe their management plan and rationale for a specific disease presentation. Here they explore the management of precursor B-cell acute lymphoblastic leukaemia (pre-B ALL) in five different institutions worldwide with a focus on those with more or less strained economies. We end with a conclusion from an expert in the field comparing and contrasting these different management styles and considering their merits and limitations.

ABSTRACT

Multimodality treatment approaches, with systemic therapies at their core, have made Hodgkin Lymphoma a highly curable cancer. Unmet needs remain. Resistance to therapy manifested by refractory and relapsed disease, and treatment related short- and long-term morbidity are the key challenges. Patient outcomes have improved in the recent past with the advent of novel therapies and are borne out of a better understanding of the disease biology and translational medicine. Antibody based therapies, more broadly immunotherapies, are leading the change in the way we treat this disease. This review looks at the tumor antigen-directed immunotherapies, and immune checkpoint inhibitors that are attempting to overcome the unmet challenges.

ABSTRACT

The aim of the study was to assess healthy tissue metabolism (HTM) using 2-deoxy-2-[18F]fluoro-D-glucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) during chemotherapy in Hodgkin lymphoma (HL) and the association of HTM with baseline metabolic tumour volume (MTV), haematological parameters, adverse events (AEs), early response and progression-free survival (PFS). We retrospectively identified 200 patients with advanced HL from the RATHL trial with [18F]FDG-PET/CT before (PET0) and following 2 cycles of chemotherapy (PET2). [18F]FDG-uptake was measured in bone marrow (BM), spleen, liver and mediastinal blood pool (MBP). Deauville score (DS) 1-3 was used to classify responders and DS 4-5, non-responders. [18F]FDG-uptake decreased significantly in BM and spleen and increased in liver and MBP at PET2 (all p < 0.0001), but was not associated with MTV. Higher BM uptake at PET0 was associated with lower baseline haemoglobin and higher absolute neutrophil counts, platelets, and white blood cells. High BM, spleen, and liver uptake at PET0 was associated with neutropenia after cycles 1-2. BM uptake at PET0 was associated with treatment failure at PET2 and non-responders with higher BM uptake at PET2 had significantly inferior PFS (p = 0.023; hazard ratio = 2.31). Based on these results, we concluded that the change in HTM during chemotherapy was most likely a direct impact of chemotherapy rather than a change in MTV. BM uptake has prognostic value in HL.

ABSTRACT

The outcomes of adult B-cell acute lymphoblastic leukemia (ALL) remain poor. Recent advancements in the field of leukemia research show potential for improved patient care. However, the adoption of research findings into clinical practice is fraught with practice- and country-specific challenges. The continued addition of new findings warrants critical evaluation for the feasibility of incorporation into clinical practice. A uniform set of evidence-based guidelines can favorably assist physicians in making optimal clinical decisions. Such a resource may also serve as a reference point for strategic planning of initiatives aimed at addressing critical barriers in the optimal management of B-cell ALL. This initiative was undertaken to seek a collaborative perspective and understand the existing challenges. Concordance-based recommendations were outlined through a systematic discussion on various aspects of treatment and management of adult B-cell ALL. The outcomes and experiences gained from this exercise will serve as a foundation for future efforts encompassing the more granular aspects of the management of B-cell ALL across the Asia-Pacific region.

ABSTRACT

The advent of immunotherapy in lymphomas, beginning with Rituximab, have led to paradigm shifting treatments that are increasingly bringing a greater number of affected patients within the ambit of durable disease control and cure. Bispecific antibodies harness the properties of the immunoglobulin antibody structure to design molecules which, apart from engaging with the target tumour associated antigen, engage the host's T-cells to cause tumour cell death. Mosunetuzumab, an anti-CD20 directed bispecific antibody was the first to be approved in follicular lymphoma, this has now been followed by quick approvals of Glofitamab and Epcoritamab in diffuse large B-cell lymphomas. This article reviews contemporary data and ongoing studies evaluating the role of bispecific antibodies in indolent b-cell non Hodgkin lymphomas. This is an area of active research and presents many opportunities in advancing the treatment of indolent lymphomas and potentially forge a chemo-free treatment paradigm in this condition.

ABSTRACT

INTRODUCTION: High-dose chemotherapy with melphalan, followed by autologous hematopoietic stem cell transplantation (AHCT) remains the standard of care for consolidation therapy of fit patients with newly diagnosed multiple myeloma (NDMM), for more than 20 years now. MATERIAL AND METHODS: This is a retrospective study of NDMM patients who underwent AHCT at our center from 2011 to 2018. Data was undertaken using the hospital electronic medical records (EMR). RESULTS: Among transplant eligible patients (which were 764), 78 patients (10.2%) underwent AHCT. The predominant stage in the study cohort was International Scoring System (ISS)-III (55%), and IgG-kappa (44%) was the commonest subtype of multiple myeloma (MM). Light chain myeloma was found in 23.5% of patients. Pretransplant, 42%, 48%, and 10% patients were in more than very good partial response (>VGPR), very good partial response (VGPR), and partial response (PR), respectively. The median duration of follow-up was 57.2 months (range: 12.1-120.2 months). The entire cohort's 5-year overall survival (OS) and progression-free survival (PFS) were 89.1% and 41.8%, respectively. CONCLUSION: Bortezomib based triplet induction regimens were effective and well tolerated in this retrospective analysis of Indian patients. We observed that AHCT effectively achieves deep and durable remission in MM.

ABSTRACT

In recent years, considerable progress has been made in the standard treatment for chronic lymphocytic leukaemia (CLL) due to the availability of new potent drugs. However, the majority of data on CLL were derived from Western populations, with limited studies and guidelines on the management of CLL from an Asian population perspective. This consensus guideline aims to understand treatment challenges and suggest appropriate management approaches for CLL in the Asian population and other countries with a similar socio-economic profile. The following recommendations are based on a consensus by experts and an extensive literature review and contribute towards uniform patient care in Asia.

ABSTRACT

Autologous chimeric antigen receptor-T (CAR-T) cell therapy has proven itself as an effective therapeutic modality for cancers, especially hematological malignancies and is emerging as a potential candidate for solid organ cancers as well. However, the accessibility to treatment has been limited due to complexities and costs associated with manufacturing a genetically modified autologous product. The centralized model of CAR-T manufacturing which has emerged as the dominant model in developed nations does not seem well-suited to the needs and realities of the developing economies. In this context, we explore the relative advantages and disadvantages of the two models from a developing nation's perspective.

ABSTRACT

BACKGROUND: Mantle cell lymphoma (MCL) is a rare type of mature B-cell lymphoid malignancy with the pathologic hallmark of translocation t(11;14) (q13, q32), which leads to an overexpression of Cyclin D1 (CCND1). The disease is also characterized by the presence of a high number of recurrent genetic alterations, which include aberrations in several cellular pathways. MCL is a heterogeneous disease with a wide range of clinical presentations and a majority presenting with aggressive disease in advanced stages. RECENT FINDINGS: Management of MCL is bereft with challenges due to its resistant and relapsing pattern. Despite improvements in remission durations, the disease is currently incurable with standard therapy and has a median survival of about 3-5 years. The use of small molecules like the bruton tyrosine kinase (BTK) and BCL2 inhibitors, for treating relapsed MCL has been established leading to a diminishing role for conventional chemotherapy. Combinations of small molecule inhibitors with or without chemoimmunotherapy, are showing promising results. Cellular therapy in the form of CAR-T cell therapy, has been approved recently. CONCLUSIONS: Personalized cancer treatment and chemo-free regimens are showing promise and results from well-planned long-term studies are evolving. In India, there is a paucity of epidemiological, clinical, and research data in this field.

ABSTRACT

Routine diagnostic biopsy tissue processing, conventional histology/immunohistochemistry (IHC) method is a multi-step and time consuming practice. With the advanced tissue dissociation protocols and panel designing, flow cytometric immunophenotyping (FCI) can be performed on diagnostic hematolymphoid tissue samples using single cell suspensions that economize steps and the time taken. Diagnostic tissue samples from lymph node, mediastinal mass, testicular biopsies and similar sites were dissociated using gentle MACS Octo-dissociator and FCI was performed thereafter. Oral tissue biopsy samples were also processed as a validation set for the protocol. 21 prospective tissue biopsy samples with suspected involvement by a known hematolymphoid neoplasm were processed and evaluated. These included B lymphoblastic lymphoma (n = 12), T lymphoblastic lymphomas (n = 3), Burkitts lymphoma (n = 3) and one case each of granulocytic sarcoma, Hodgkin lymphoma and granulomatous disease. Tissue FCI and IHC were found concordant with identified profile FCI obtained from blood/bone marrow analyses. FCI can produce a highly sensitive and reliable report, within hours, by processing fresh tumor tissue samples from suspected hematolymphoid malignancies. This method can be considered as an effective adjunct to IHC and can be applicable in routine clinical diagnostics, especially in cases that needs quick diagnosis and immediate clinical treatment.

ABSTRACT

Transthyretin cardiac amyloidosis (ATTR-CM) is a rare and under-recognized disorder characterized by the aggregation of transthyretin-derived insoluble amyloid fibrils in the myocardium. Heterogeneity of symptoms at presentation, makes its diagnosis often delayed. An expert panel gathered on a virtual platform across India to conduct a meeting for developing a guiding tool for ATTR-CM diagnosis. The panel recommended younger age (≥40 years) for suspecting ATTR-CM and thick-walled non-dilated hypokinetic ventricle was considered as one of the important red flags. Electrocardiogram (ECG) and echocardiography (ECHO) findings were recommended as primary tests to raise the suspicion while nuclear scintigraphy and hematological tests were recommended to confirm the diagnosis and rule out amyloid light-chain (AL) amyloidosis. Cardiac magnetic resonance (CMR) and biopsy were recommended in case of ambiguity in the presence of red flags. Considering the lack of expert guidelines in the Indian scenario, a standardized diagnostic algorithm was also proposed.

ABSTRACT

BACKGROUND: In the present systematic literature review, we sought to describe the burden and treatment practices of adult acute lymphoblastic leukemia (ALL) in India, which reflect the realities and outcomes in a middle-income country. MATERIALS AND METHODS: We conducted a search for reported studies using terms such as "adult ALL," "epidemiology," and "treatment" in the Medline, Embase, Cochrane, and other database sources. We obtained 249 articles and 18 conference abstracts reported until December 2019. A total of 40 studies were selected to qualitatively summarize the data. RESULTS: The proportion of ALL among adult patients diagnosed with acute leukemia at reporting institutions from 16 Indian studies ranged from 7.3% to 57.8%. Most studies were performed in Northern India (n = 12), had a male preponderance (range, 57%-80%), and had a predominance of B-ALL (range, 65.2%-75.9%). The treatment protocols used for ALL included MCP-841, BFM (Berlin-Frankfurt-Münster)-90, chemotherapy plus a tyrosine kinase inhibitor, GMALL (German Multicenter Study Group for Adult Acute Lymphoblastic Leukemia), and hyper-CVAD (cyclophosphamide, vincristine, doxorubicin, dexamethasone). The complete remission rates and median overall survival for these protocols ranged from 46.7% to 91.4% and 7 to 46 months, respectively. The overall relapse rates were 24.3% to 57.1% within median time of 9 to 24 months, with bone marrow the most frequent relapse site. After relapse, most patients had chosen palliative therapy (range, 78.7%-96.0%). The major treatment-related toxicities included neutropenia, myelosuppression, and infection. CONCLUSIONS: The results from Indian studies on adult ALL are heterogeneous, reporting a diverse incidence and poor overall outcomes using varied non-contemporaneous treatment protocols adapted from the developed world. A comprehensive countrywide approach to diagnosis, treatment, and follow-up and the potential incorporation of novel therapies could improve the prognosis and outcomes of adult ALL in India.

ABSTRACT

PAS, by replacing part of the plasma in the platelet storage bag, reduces post transfusion allergic reactions and DHTR in the recipient. In this study we compared quality and efficacy of PAS and usual plasma stored platelets. Platelet concentration, content, MPV, pH, swirling, LDH and glucose concentration were tested in SDPs after preparation and on the day of transfusion; and compared between control (plasma-stored SDP) and study (PAS-stored SDP) groups. CCI was compared between the two groups. Transfusion reactions were also noted. In both groups quality parameters were similar except glucose [significantly decreased (p < 0.001) in plasma] and LDH [increased significantly (p: -0.005) in PAS]. CCI was similar in both groups. Transfusion reaction rate were 0.012% and 0.049% in both groups respectively. Quality and post-transfusion efficacy in both groups were similar. PAS stored platelets may be transfused in multi-transfused patients with allergic manifestations and in minor ABO incompatible transfusions.

ABSTRACT

Hypodiploidy with < 40 chromosomes is associated with poor prognosis in B cell precursor acute lymphoblastic leukemia. In some patients, the hypodiploid clone undergoes endoreduplication, resulting in doubling of the number of chromosomes and masquerades as a high hyperdiploid BCP-ALL. Karyotyping reveals metaphases with 50-79 chromosomes masking the hypodiploid clone. Identifying hypodiploidy in such cases requires awareness of non random alterations of chromosomal copy numbers found in hypodiploid BCP-ALL. We used a systematic strategy to identify masked hypodiploidy integrating targeted fluorescence in situ hybridization (FISH) analysis directed towards identifying monosomies of chromosomes 7, 15 and 17 and flow cytometry-based ploidy analysis (FCPA). Of 445 patients diagnosed as BCP ALL, 2.9% (13/445) were classified as hypodiploid including patients with masked hypodiploidy. Karyotype analysis showed hypodiploidy in 3 patients, near triploidy in 4 patients and normal karyotype in 6 patients. Four patients with near triploid clone on karyotype showed either bimodal peak (2 patients) or single low hypodiploid peak (1 patient) or only near triploid peak (1 patient) on FCPA. All 6 patients with normal karyotype revealed either bimodal peak (4 patients) or hypodiploid peak (2 patients) on FCPA. Targeted FISH analysis unmasked hypodiploid clone showing monosomies of chromosomes 7, 15 and 17 in all ten patients. Our algorithm successfully identified masked hypodiploidy in patients, including those with endoreduplication (4 patients) and normal karyotype (6 patients). Integrating FCPA with targeted FISH analysis provides a practical, sensitive and specific approach to identify masked hypodiploidy in low resource settings.

ABSTRACT

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is the commonest subtype of lymphoma in the elderly and poses unique challenges in this group of patients. There is a need for more information on real-world outcomes across economic disparities. METHODS: Electronic Medical Record of 3,087 lymphomas (>18 years) were evaluated retrospectively, of which 842 (27%) patients were ≥65 years. Two hundred and twelve patients who were ≥65 years received first line treatment for DLBCL between May 2011 and Dec 2016. Demography, clinical features, associated co-morbidities, first line treatment outcomes and hospital costs were analysed. Patients were followed up till March 2020. RESULTS: The median age at presentation was 71 years. Gender ratio was 2.5:1. 38% patients presented with early-stage disease, 37% with low and low-intermediate International prognostic index, 49% with nodal disease. One or more co-morbidities were present in 58%. The commonest extra nodal site was gastro-intestinal (29%). Two-thirds of the patients presented with non-Germinal centre B subtype. The overall response (OR) to treatment was 72.5%. Patients who received anthracycline-based therapy (n = 124) and rituximab-based therapy (n = 159) had a median progression free survival (PFS), not reached and 47.0 months, respectively, versus 10 months and 7.9 months, respectively, for patients receiving non-anthracycline and non-rituximab therapies. At a median follow-up of 24 months, the 5-year overall survival and PFS are 44% and 41%, respectively, for the entire cohort. CONCLUSIONS: DLBCL is a curable lymphoma in elderly patients with standard anthracycline and rituximab-based therapies. Improvement in outcomes largely depends on social and financial support to complete the scheduled treatments.

ABSTRACT

The prevailing corona virus disease 19 (COVID-19) pandemic has adversely affected the healthcare services globally. Hematopoietic cell transplantation (HCT) is considered as the preferred treatment option for several hematological malignancies, and HPC collection facilities have to function continuously along with implementing safety measures. Based on the national and international guidelines, we implemented additional measures and modifications to our standard operating procedure (SOP) to ensure secure HPC collection from patients as well as donors. Here, we report our experience with HPC collection and processing from 1st January, 2020 until 31st December, 2020. We collected 59 HPC products through apheresis and 41 cryopreservation procedures. Compared to 2019, there was a 33% decrease in the number of HPC transplants and 31% reduction in HPC collection procedures. However, we report an 86% (13 procedures) increase in the cryopreservation of HPC products from related donors, as several organizations recommend cryopreservation of HPC products. We report our institutional experience to better understand the impact of COVID-19 on HCT services in a tertiary care center in the developing world. It may also help in being prepared for any future waves of COVID-19 cases.

ABSTRACT

INTRODUCTION: Despite high cure rates with standard treatment, 30% patients with Hodgkin lymphoma develop relapsed or refractory (R/R) disease. Salvage therapy followed by autologous hematopoietic cell transplantation (HCT) is considered standard of care. Brentuximab Vedotin (Bv) in combination with Bendamustine (B) has been tested in the salvage setting with promising results. MATERIALS AND METHODOLOGY: We conducted a single centre retrospective chart review of patients who received BBv salvage therapy to determine its activity and safety in patients with R/R classical Hodgkin lymphoma (HL). Between May 2011- December 2019, 179 patients were diagnosed with R/R HL. RESULTS: Thirty patients received BBv [median age: 30 (15-59) years, females (n=15)]. Primary refractory disease in 19 patients (63%), and 26 patients (87%) had advanced stage at treatment. Most patients received BBv after 2 prior lines of therapy [n=16 (53%)]. The median number of cycles of BBv were 3 (1-6). The number of BBv cycles delivered as outpatient was 63%. The most common Grade III/IV hematological adverse event was neutropenia [n=21, (70%)], while grade III/IV non-hematological toxicities included infections in 4 (13%), neuropathy in 4(13%), skin rash in 2 (7%), GI toxicities in 3 (10%) and liver dysfunction in 2 (7%) patients. The ORR and CR rates were 79% and 62%, respectively. Seventeen patients (57%) underwent an autologous HCT and 8 (26%) underwent an Allogeneic HCT (all haploidentical). The median follow up time from BBv administration was 12 months. Six patients died: 2 = disease progression, and 4 = non-relapse causes (Infection and sepsis = 2, GVHD=2). In addition to this, one patient progressed soon after HCT and another patient relapsed 22 months post HCT. Three year Overall survival (OS) and Event free survival (EFS) probability post-BBv treatment was 75% and 58%, respectively. OS and EFS analysis based on response (viz., CMR) to BBv demonstrated that patients in CMR had better survival probability [93% (p=0.0022) 3yr-OS and 72% (p=0.038) 3yr-EFS probability]. CONCLUSIONS: BBv is an active and well-tolerated salvage treatment for patients with R/R HL, even in refractory and advanced settings. In middle-income settings, cost constraints and access determine patient uptake of this regimen.

ABSTRACT

Hemoglobin E-ß-thalassemia is a common ß-thalassemia that has a variable presentation from mild to severe life-threatening anemia. We describe such a case, who presented with severe anemia and multiple allo-antibodies. Our case illustrates the role of thalidomide in transfusion-sparing therapies in patients with transfusion-dependent thalassemia and challenges in the blood bank.
