RESUMEN
BACKGROUND: Infections by multidrug-resistant organisms (MDRO) are a major hurdle in hematopoietic stem-cell transplants (HSCTs). Conditioning regimens lead to mucosal barrier injury, which in-turn leads to transmigration of gut bacteria and sepsis. Pre-transplant stool and throat surveillance cultures can guide empirical antibiotic policy during the neutropenic period. In this paper, we document colonization with MDRO in pre-transplant surveillance cultures and the correlation with bloodstream infections in HSCT patients and analyze transplant outcomes with respect to these infections. METHODS: A single-center, retrospective study on HSCT was performed between January 2021 and December 2021. The incidence of bacterial infections, percentage of MDROs, correlation with pre-transplant stool/throat surveillance cultures, and their impact on overall 100-day and post-100-day to 6-month post-transplant survival were analyzed. RESULTS: Sixty-four patients were included in the study. Pre-transplant stool surveillance cultures were positive for MDRO in 85.9% of patients. Almost half (48.5%) of the isolates were positive for carbapenemase-producing genes (mainly New Delhi metallo-beta-lactamase-1 [NDM-1] and oxacillinase-48 [OXA-48]). Eighteen patients (18/64, 28%) had a positive blood culture for MDRO in the peri-engraftment neutropenic period. Correlation between surveillance and blood cultures was seen in 61% (11/18) of patients. All-cause mortality was 14.1% (9/64) and 25% (16/64) in patients at 100 days and 6 months post-HSCT, respectively. The 100-day and post-100-day all-cause mortality rates were higher in patients with Gram-negative MDRO bloodstream infections (p < .012 and <.008, respectively). CONCLUSION: MDRO infections can adversely affect HSCT outcomes. Pre-transplant stool and throat surveillance cultures may guide empirical antibiotic policy and lead to favorable transplant outcomes.

Non-Hodgkin's lymphoma (NHL) is a common hematological malignancy. The age-adjusted incidence rates for NHL in men and women in India are 2.9/100,000 and 1.5/100,000, respectively. These are about one fourth of the incidence rates reported from Western Europe or North America. Within India, the incidence is several-fold higher in urban cancer registries compared to rural areas; the incidence being higher in metropolitan cities and Indian immigrants suggesting that urban lifestyles and economic progress may increase the cancer incidence. Compared to developed nations, the key differences in the presentation in India include: median age of 54 years (almost a decade less), higher male to female ratio, higher proportion of patients with B-symptoms (40-60 vs. 20-30%), poor ECOG performance status (≥2) at diagnosis (50 vs. 20-30%), higher frequency of diffuse large B-cell lymphomas (60-70 vs. <40%), lower frequency of follicular NHL (<20 vs. 30-40%) and T-cell type in 10-20 vs. <10%. The estimated mortality rate due to NHL is higher in India than in North America and Western Europe. Diagnostic and treatment delays, incorrect diagnosis and inappropriate or suboptimal treatment may be possible reasons for the poor outcome. Any improvement in the outcomes for NHL in India will require a nationwide approach, e.g. creation of several regional and district-level centers with expertise in lymphoma management. Collection of data on patient- and disease-related characteristics, treatment outcome, development of infrastructure, centralized review of histopathology subtype, novel treatment protocols, rigorous follow-up, training of staff, and financial support towards treatment could be possible strategies to improve the outcome.

BACKGROUND & OBJECTIVES: Multiple myeloma (MM) is a plasma cell malignancy characterized by cytogenetic heterogeneity. In comparison with conventional karyotyping, fluorescence in situ hybridization (FISH) can efficiently detect various genetic changes in non-cycling plasma cells in 50-90 per cent of MM cases. The present study was undertaken in MM patients to evaluate the frequency and clinico-pathological significance of various cytogenetic abnormalities in the Indian population. METHODS: Interphase FISH was applied on purified plasma cells of 475 patients with MM using specific probes. Interphase FISH for 1q gain/1q amplification was performed on a separate group of 250 newly diagnosed MM patients. RESULTS: Low frequency of Δ13 [-13/del(13q)] (32%) and t(11;14) (5%) was observed in our 475 patients probably due to ethnic diversity. Clustering of Δ13, del(17)(p13.1) and IgH translocations in non-hyperdiploidy confirmed prognostic significance of ploidy in MM. t(4;14) and del(17)(p13.1) were high-risk groups due to correlation with high serum ß2-microglobulin, increased plasma cells and advanced disease. Hyperdiploidy and t(14;16) were associated with higher age group. In a separate group of 250 patients, 1q amplification [amp(1q)] in combination with Δ13 and/or del(17p) with t(4;14) revealed association with adverse clinico-laboratory features, which confirmed progressive role of amp(1q) with adverse prognostic impact. Amp(1q) was clustered at 1q21 and 1q25 loci. INTERPRETATION & CONCLUSIONS: Based on our findings, it appears that comprehensive analysis of various cytogenetic aberrations by interphase FISH is a powerful strategy being adapted for risk stratification of MM.

BACKGROUND: Cancer incidence and mortality is increasing in the developing world. Inequities between low-, middle-, and high-income countries affect disease burden and the infrastructure needs in response to cancer. We surveyed early-career oncologists attending workshops in clinical research in three countries with emerging economies about their perception of the evolving cancer burden. METHODS: A cross-sectional survey questionnaire was distributed at clinical trial concept development workshops held in Beijing, Lahore, Karachi, and Mumbai at major hospitals to acquire information regarding home-country health conditions and needs. RESULTS: A total of 100 respondents participated in the workshops held at major hospitals in the region (India = 29, China = 25, Pakistan = 42, and other = 4). Expected consensus on many issues (e.g., emergence of cancer as a significant health issue) was balanced with significant variation in priorities, opportunities, and challenges. Chinese respondents prioritized improvements in cancer-specific care and palliative care, Indian respondents favored improved cancer detection and advancing research in cancer care, and Pakistani respondents prioritized awareness of cancer and improvements in disease detection and cancer care research. For all, the most frequently cited opportunity was help in improving professional cancer education and training. CONCLUSION: Predominantly early-career oncologists attending clinical research workshops (in China, India, and Pakistan) identified needs for increasing clinical cancer research, professional education, and public awareness of cancer. Decision makers supporting efforts to reduce the burden of cancer worldwide will need to factor the specific needs and aspirations of health care providers in their country in prioritizing health policies and budgets.

Cancer is one of the major non-communicable diseases posing a threat to world health. Unfortunately, improvements in socioeconomic conditions are usually associated with increased cancer incidence. In this Commission, we focus on China, India, and Russia, which share rapidly rising cancer incidence and have cancer mortality rates that are nearly twice as high as in the UK or the USA, vast geographies, growing economies, ageing populations, increasingly westernised lifestyles, relatively disenfranchised subpopulations, serious contamination of the environment, and uncontrolled cancer-causing communicable infections. We describe the overall state of health and cancer control in each country and additional specific issues for consideration: for China, access to care, contamination of the environment, and cancer fatalism and traditional medicine; for India, affordability of care, provision of adequate health personnel, and sociocultural barriers to cancer control; and for Russia, monitoring of the burden of cancer, societal attitudes towards cancer prevention, effects of inequitable treatment and access to medicine, and a need for improved international engagement.

Melphalan-induced encephalopathy is a rare complication observed in patients undergoing autologous stem cell transplantation (ASCT) and is characterized by symptoms ranging from drowsiness to seizures. Previous reports have described similar cases, including a review of a large cohort of patients in whom melphalan-associated encephalopathy was identified in 2% of the patients undergoing ASCT. We describe the case of a 63-year-old male with Multiple Myeloma and underlying chronic kidney disease (CKD) who underwent ASCT with a reduced dose of melphalan due to renal dysfunction in complete remission following induction therapy and subsequent neurological deterioration, which necessitated an extensive evaluation of several neurological and infective etiologies. In this report, we highlight that melphalan-associated encephalopathy is a distinct entity complicating ASCT in patients with myeloma, especially in those with preexisting renal insufficiency, and consider its management.
RESUMEN
ABSTRACT: Using one's own immune system for curing cancer has been an active field of research in cancer biology and therapeutics. One such opportunity in cellular immunotherapy is adoptive cell transfers. With the recent approval of CAR-T therapy as a cancer treatment, a whole new paradigm of cancer treatment has opened-up, with a ray of hope for relapsed/refractory cancer patients. Despite promising clinical outcomes, the therapy is in its early phase and remains out of reach for most patients due to its high cost and logistic challenges. In India, these therapies are unavailable and further confounded by the economic challenges and a large population. In this review, we discuss various aspects of T-cell immunotherapies with a special focus on CAR-T in the Indian scenario. We touch upon the basic scientific aspects, mechanism of action, manufacturing, clinical aspects and commercial aspects of the CAR-Tcell therapies and its future worldwide and in India.
RESUMEN
Background: Diffuse large B-cell lymphoma (DLBCL) is an aggressive and the most common type of non-Hodgkin lymphoma (NHL). The clinical use of rituximab has improved the treatment response and survival of patients with DLBCL. The introduction of rituximab biosimilar into healthcare system has helped in providing a cost-effective treatment to B-cell lymphoid malignancies as standard of care and has improved access to patients worldwide. The aim of this study was to observe the real-world effectiveness and safety of Reditux™ and Ristova® in DLBCL patients. Methods: Observational study in adults with DLBCL receiving Reditux™ or Ristova® across 29 centers in India (2015-2022). Effectiveness and safety were assessed up to 2 years after first dose. Results: Out of 1,365 patients considered for analysis, 1,250 (91.6%) were treated with Reditux™ and 115 (8.42%) with Ristova®. At 2 years, progression-free survival (PFS) 69% [hazard ratio (HR), 1.16; 95% CI, 0.80-1.67], overall survival (OS) 78.7% (HR, 1.20; 95% CI, 0.78-1.86), response rates, quality of life (QoL), and overall safety in both the cohorts were comparable. The best overall response rate (BORR) at 6 months was comparable with no statistically significant differences between the Reditux™ and the Ristova® cohorts (89.2% vs. 94.3%). In multivariate analysis, BCL-2 and VAS were significant prognostic factors for PFS. Conclusion: Reditux™ and Ristova® were comparable in real-world setting. Clinical Trial Registration: ISRCTN registry, identifier (ISRCTN13301166).
RESUMEN
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.

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.
RESUMEN
Acute promyelocytic leukemia (APL) is characterized by a reciprocal translocation t(15;17)(q22;q21) leading to the disruption of Promyelocytic leukemia (PML) and Retionic Acid Receptor Alpha (RARA) followed by reciprocal PML-RARA fusion in 90% of the cases. Fluorescence in situ hybridization (FISH) has overcome the hurdles of unavailability of abnormal and/or lack of metaphase cells, and detection of cryptic, submicroscopic rearrangements. In the present study, besides diagnostic approach we sought to analyze these cases for identification and characterization of cryptic rearrangements, deletion variants and unknown RARA translocation variants by application of D-FISH and RARA break-apart probe strategy on interphase and metaphase cells in a large series of 200 cases of APL. Forty cases (20%) had atypical PML-RARA and/or RARA variants. D-FISH with PML/RARA probe helped identification of RARA insertion to PML. By application of D-FISH on metaphase cells, we documented that translocation of 15 to 17 leads to 17q deletion which results in loss of reciprocal fusion and/or residual RARA on der(17). Among the complex variants of t(15;17), PML-RARA fusion followed by residual RARA insertion closed to PML-RARA on der(15) was unique and unusual. FISH with break-apart RARA probe on metaphase cells was found to be a very efficient strategy to detect unknown RARA variant translocations like t(11;17)(q23;q21), t(11;17)(q13;q21) and t(2;17)(p21;q21). These findings proved that D-FISH and break-apart probe strategy has potential to detect primary as well as secondary additional aberrations of PML, RARA and other additional loci. The long-term clinical follow-up is essential to evaluate the clinical importance of these findings.
RESUMEN
Coronavirus pandemic has increased human disease burden, as well as economic distress globally. Being in an immunocompromised state, patients with cancer comprise an important at-risk population for novel coronavirus disease 2019 (COVID-19) infection. It is necessary to modify individualized clinical management for every cancer patient in the context of the ongoing COVID-19 pandemic. Simultaneously, additional safety precautions for the cancer care providers are mandatory. This review will provide general recommendations in the Indian context optimizing the same.
RESUMEN
BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is the commonest subtype of lymphoma, standard CHOP was the treatment of choice, 42% of patients received rituximab, and 29% of patients were lost to follow-up during therapy, were reported in a study that collected retrospective data at 13 public and private hospitals for patients diagnosed with lymphoma between January 2005 and December 2009. The OncoCollect Registry was set up in 2017 to address the challenges in the collection of retrospective data through chart review, recording access to anthracycline and rituximab-based treatment, and to study outcomes and any improvement in the patient follow-up. METHODOLOGY: The OncoCollect Lymphoma group registry was set up at a national level with 9 participating centers. Lymphoma patients registered at these centers between 2011 and 2017 were included. The clinical features, prognostic stratification, associated comorbidities, response to first-line treatment, and 3-year outcomes of adult patients with DLBCL were analyzed. RESULTS: Of the 5,886 lymphoma patients registered in the OncoCollect registry, 2,581 (44%) had DLBCL. A total of 1,961 were evaluable for frontline therapy. The median age at presentation was 57 years. Gender ratio was 1.6:1. At presentation, 43% were early stage, 70% had low and low intermediate IPI, 53% had extranodal disease, and 30.9% had one or more comorbidities (data available for 1,136 patients). The commonest extra nodal site was gastro-intestinal (23.98%) followed by head and neck (19.24%). The overall response rate was 79.29%. Complete remission was seen in 61.75%, partial response in 17.5%, stable disease in 4.3%, and progression in 7.9%. Patients who received anthracycline-based therapy (86.7%) and rituximab-based therapy (83.7%) had a 3-year event-free survival (EFS) of 69.67% and 68.48%, respectively. With a median follow-up of 33 months, the 3-year overall Survival (OS) and EFS were 75.37% and 66.58%, respectively. CONCLUSIONS: DLBCL remains the commonest (44%) lymphoma subtype and is curable with standard anthracycline- and rituximab-based therapies. The availability of rituximab has increased the proportion of patients receiving standard chemoimmunotherapy.
RESUMEN
This case emphasizes that, with the availability of novel immunotherapy agents (Daratumumab), and repurposed use of bortezomib, a patient with HIV-negative relapsed PBL can be treated successfully and consolidated with an allogeneic haploidentical hematopoietic cell transplantation.
RESUMEN
BACKGROUND: Hodgkin's lymphoma (HL) is one of the most curable malignancies with a 5-year survival of over 80%. Most published literature from low-middle income countries comes from single institute experience. METHODOLOGY: The OncoCollect Lymphoma group registry was set up in 2017 and has 9 major participating sites across India. Data of newly diagnosed classical HL (CHL) patients, treated between 2011 and 2017, were collected using OncoCollect software. The clinical features, subtypes, prognostic stratification, treatment patterns, response to first-line treatment, and 5-year outcomes were analyzed. All statistical analysis was done using Microsoft R Open statistical software linked to OncoCollect software. RESULTS: There were 939 newly diagnosed CHL patients with a median age of 38 (range, 18-99) years at presentation. The male-to-female ratio was 2.07:1. Histological subtypes included mixed cellularity, CHL (MC, CHL), nodular sclerosis, CHL (NS, CHL), lymphocyte-rich, CHL (LR, CHL), and lymphocyte-depleted, CHL (LD, CHL), in 60.60%, 26.94%, 9.80%, and 2.66%, respectively. At presentation, 50.43% had B symptoms and 53.35% had advanced disease. 29.71% of advanced-stage patients had high Hodgkin IPI score. 79% and 21% of patients received 1st-line treatment with chemotherapy alone or combined modality treatment with chemotherapy and radiotherapy. The most common first-line chemotherapy was ABVD-based regimen (94.68%). The overall response rate was 93.48%. Complete response rates among early-stage favorable and unfavorable risk groups were 92.73% and 86.79%, and those among advanced-stage low- and high-risk groups were 76.64% and 69.78%, respectively. The median relapse-free follow-up duration was 51 months (IQR 22-69). A significant difference was found in 5-year EFS between the early- and advanced-stage disease 83.53% and 73.55% (p = 0.00087), respectively. Similarly, significant difference was found in EFS among early-stage patients treated with a combination of 4-cycle chemotherapy and radiotherapy vs. chemotherapy alone 88.57% and 66.33% (p = 0.0042), respectively. CONCLUSIONS: In this large cohort from India, survival of patients with HL was comparable to the developed world. With a median follow-up of 51 months, the 5-year EFS and OS of all patients were 78.24% and 83.63%, respectively.
RESUMEN
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.
RESUMEN
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.
RESUMEN
Acute promyelocytic leukemia (APL) remains the most curable myeloid leukemia made feasible through effective use of two differentiating agents, all trans retinoic acid (ATRA) and arsenic trioxide (ATO) with or without chemotherapy (CT). However, early morbidity and mortality remains a problem. With the objective of reducing early death a strategy of sequential induction ATO followed by consolidation ATRA in combination with CT was adopted by our group. The long-term outcomes of patient of APL treated on this sequential approach at our center was analyzed. In this retrospective analysis of prospectively maintained database consecutive adult patients with APL irrespective of their Sanz risk group were treated using a protocol of ATO (10 mg IV infusion over 3 h daily for 45 days) in the first phase followed by ATRA (45 mg/m2 for 60 days) in combination with Daunorubicin (60 mg/m2 for 3 days × 3 cycles) in second phase. All patients received maintenance ATRA (45 m/m2 for 15 days every 3 months) for a period of 18 months in phase 3. Patients were monitored for cytogenetic and molecular responses after phase 1 and 2. All patients were followed up for toxicity, event free and overall survival. 131 consecutive patients were treated in this study. At a median follow up of 60 months, 84.81% patients are alive with an overall event free survival (EFS) of 77.82%. Sanz low risk patients fared better (85%) versus intermediate and high-risk patients who had a 76% EFS. Proportion of patients alive at last follow up were 100% in Sanz low risk group and 82% in intermediate and high-risk group. The sequential schedule showed excellent tolerance and toxicity profile when treating newly diagnosed APL. The long-term follow-up data shows comparable if not better survival compared with the published real-world data and this has been consistent across all risk group.
