Ten-year follow-up of outcomes, patterns of care, and psychosocial burden in adolescent and young adult patients with bone sarcomas from a large cohort in a low-income and middle-income country.

Background: The care of adolescents and young adults (AYAs) with bone sarcomas involves unique challenges. The objectives of this study were to identify challenges and evaluate long-term outcomes of these patients from India who received treatment with novel protocols.

Methods: This prospective cohort study included AYA patients (aged 15-39 years) with osteosarcoma and Ewing sarcoma (ES), who were treated uniformly at the authors' institute using unique protocols (OGS-12 and EFT-2001) from 2011 to 2021 and from 2013 to 2018, respectively.

Emergence of SARS-CoV-2 Variants Are Induced by Coinfections With Dengue.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that emerged in late 2019 has accumulated a series of point mutations and evolved into several variants of concern (VOCs), some of which are more transmissible and potentially more severe than the original strain. The most notable VOCs are Alpha, Beta, Gamma, Delta, and Omicron, which have spread to various parts of the world. This study conducted surveillance in Jashore, Bangladesh to identify the prevalence of SARS-CoV-2 coinfected with dengue virus and their genomic effect on the emergence of VOCs.

Performance of Low-Dose Immunotherapy and Standard-Dose Immunotherapy in Microsatellite Instability-High Metastatic Colorectal Cancer: Real-World Data (CLouD-High Study).

Purpose: Standard-dose immune checkpoint inhibitors (SD-ICIs) are the standard of care as initial therapy in microsatellite instable-high (MSI-H) advanced/metastatic colorectal adenocarcinomas (mCRC), but there are preclinical data to suggest that low-dose ICIs (LD-ICI) might also have similar efficacy.

Materials And Methods: A retrospective study of patients with MSI-H mCRC receiving ICIs between June 2017 and January 2023 was conducted. The primary end point of the study was 12-month progression-free survival (PFS), which was computed using the Kaplan-Meier method.

Clinical characteristics, outcomes and prognostic factors in KRAS mutant lung cancers: experience from a tertiary care cancer center in India.

Objectives: Kirsten rat sarcoma viral oncogene homologue () mutations in lung cancers, long considered untargetable, have had a recent rise in interest due to promising data of agents targeting p.G12C. As Indian data are scarce, we sought to identify baseline clinical characteristics, prognostic factors and outcomes of lung cancer patients with mutations at our hospital.
