Background: Measurable residual disease (MRD) is becoming a cornerstone in the multiple myeloma (MM) management; however, its implementation in India faces several challenges. This Delphi survey aimed to gather expert consensus on the current practices, and barriers in MRD monitoring in MM in India.

Methods: A 3-round Delphi process (2 e-surveys and 1 in-person meeting) was conducted with hematologists, pathologists, and oncologists managing MM in India.

BMI-1 Modulation and Trafficking During M Phase in Diffuse Intrinsic Pontine Glioma.

BMI-1 (B cell-specific Moloney murine leukemia virus integration site 1) has been implicated in both normal and cancer cell biology. While the canonical function of BMI-1 involves epigenetic repression, novel extra-nuclear functions have been recently reported. In the present study, we demonstrate that the phosphorylation of BMI-1 in diffuse intrinsic pontine glioma (DIPG) cells occurs in M phase and that triggers simultaneous translocation of the phosphorylated BMI-1 to the cytoplasm.

The spatial distribution of intermediate fibroblasts and myeloid-derived cells dictate lymph node metastasis dynamics in oral cancer.

Background: Oral cancer poses a significant health challenge due to limited treatment protocols and therapeutic targets. We aimed to investigate the invasive margins of gingivo-buccal oral squamous cell carcinoma (GB-OSCC) tumors in terms of the localization of genes and cell types within the margins at various distances that could lead to nodal metastasis.

Methods: We collected tumor tissues from 23 resected GB-OSCC samples for gene expression profiling using digital spatial transcriptomics.

Uracil as a biomarker for spatial pyrimidine metabolism in the development of gingivobuccal oral squamous cell carcinoma.

No biomarker has yet been identified that allows accurate diagnosis and prognosis of oral cancers. In this study, we investigated the presence of key metabolites in oral cancer using proton nuclear magnetic resonance (NMR) spectroscopy to identify metabolic biomarkers of gingivobuccal oral squamous cell carcinoma (GB-OSCC). NMR spectroscopy revealed that uracil was expressed in 83.

Preclinical pediatric brain tumor models for immunotherapy: Hurdles and a way forward.

Brain tumors are the most common solid tumor in children and the leading cause of cancer-related deaths. Over the last few years, improvements have been made in the diagnosis and treatment of children with Central Nervous System tumors. Unfortunately, for many patients with high-grade tumors, the overall prognosis remains poor.

A Pilot Study to Determine the Utility of Automated Tissue Dissociator for Flowcytometry Based Evaluation of Hematolymphoid Tumor Tissue Biopsies.

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.

Not so 'rare'-an example of malignant melanoma in India: report from a tertiary cancer centre.

Purpose: Malignant melanoma (MM) is rare in India. Indian data on demography and treatment outcome on advanced MM is very limited in the literature.

Materials & Methods: This is a retrospective study of advanced MM treated between January 2013 and December 2020.

Development of a Highly Specific, Selective, and Sensitive Fluorescent Probe for Detection of Mycobacteria in Human Tissues.

Tuberculosis (TB), including extrapulmonary TB, is responsible for more than one million deaths in a year worldwide. Existing methods of mycobacteria detection have poor sensitivity, selectivity, and specificity, especially in human tissues. Herein, the synthesis of a cholic acid-derived fluorescent probe (P4) that can specifically stain the mycobacterium species is presented.

Impact of COVID-19 on peripheral stem cell collection and preservation at a hematopoietic cell transplant center in India: Experience 2020.

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.

A Systematic Cytogenetic Strategy to Identify Masked Hypodiploidy in Precursor B Acute Lymphoblastic Leukemia in Low Resource Settings.

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.

COVID diagnostics by molecular methods: A systematic review of nucleic acid based testing systems.

Background: The selection of appropriate kit and PCR equipment for the detection of SARS CoV-2 is critically important in view of many options available in the diagnostic market. Since last year many molecular products are available for COVID-19 diagnostics., some of these diagnostics have become commercially available for healthcare workers and clinical laboratories.

A pilot radiogenomic study of DIPG reveals distinct subgroups with unique clinical trajectories and therapeutic targets.

An adequate understanding of the relationships between radiographic and genomic features in diffuse intrinsic pontine glioma (DIPG) is essential, especially in the absence of universal biopsy, to further characterize the molecular heterogeneity of this disease and determine which patients are most likely to respond to biologically-driven therapies. Here, a radiogenomics analytic approach was applied to a cohort of 28 patients with DIPG. Tumor size and imaging characteristics from all available serial MRIs were evaluated by a neuro-radiologist, and patients were divided into three radiographic response groups (partial response [PR], stable disease [SD], progressive disease [PD]) based on MRI within 2 months of radiotherapy (RT) completion.

Diffuse Intrinsic Pontine Glioma Cells Are Vulnerable to Mitotic Abnormalities Associated with BMI-1 Modulation.

Diffuse intrinsic pontine glioma (DIPG) is a poor-prognosis pediatric brain tumor with a median survival of less than 1 year. No effective therapy is currently available, and no therapeutic advances have been made in several decades. We have previously identified BMI-1 as a potential therapeutic target in DIPG and have shown that BMI-1 is highly expressed in DIPG tumors regardless of histone 3 subtype.

The importance of intra- and inter-institutional networks for capacity building in severe acute respiratory syndrome coronavirus 2 reverse transcription polymerase chain reaction services: experience from an oncology centre in eastern India.

High-throughput, accurate, cost-effective and rapid testing for severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) is the need of the hour in face of the global coronavirus disease pandemic. This target is achievable, within a relatively short time through capacity building of reverse transcription polymerase chain reaction (RT-PCR) tests by utilising the strengths of intra and inter institutional networks. These networks act as force multiplier for vital resources which are required for capacity building, namely, leadership, expertise, equipment, space, infection control inputs and human resources.

Thalidomide in Patients with Transfusion-Dependent E-Beta Thalassemia Refractory to Hydroxyurea: A Single-Center Experience.
