Review of the unmet medical need for vaccination in adults with immunocompromising conditions: An Indian perspective.

Immunocompromised (IC) populations are at increased risk of vaccine-preventable diseases (VPDs). In India, the concern of VPDs in IC populations is particularly acute due to the prevalence of crowded living situations, poor sanitation and variable access to healthcare services. We present a narrative review of IC-related disease and economic burden, risk of VPDs and vaccination guidelines, based on global and India-specific literature (2000-2022).

Accurate Screening for Early-Stage Breast Cancer by Detection and Profiling of Circulating Tumor Cells.

Background: The early detection of breast cancer (BrC) is associated with improved survival. We describe a blood-based breast cancer detection test based on functional enrichment of breast-adenocarcinoma-associated circulating tumor cells (BrAD-CTCs) and their identification via multiplexed fluorescence immunocytochemistry (ICC) profiling for GCDFP15, GATA3, EpCAM, PanCK, and CD45 status.

Methods: The ability of the test to differentiate BrC cases ( = 548) from healthy women ( = 9632) was evaluated in a case-control clinical study.

Management of human epidermal growth factor receptor 2-negative metastatic breast cancer: Role of poly adenosine diphosphate (ADP-ribose) polymerase inhibitors.

Human epidermal growth factor receptor 2 (HER2)-negative subset is the most heterogeneous group of metastatic breast cancers (MBCs) as it includes both hormone receptor (HR)-positive and HR-negative breast cancer (or TNBC), which have different therapies and treatment challenges. Though endocrine therapy (ET) remains the treatment backbone in HR-positive HER2-negative cases, about 40% of the patients show intrinsic or acquired resistance to ET due to multiple mechanisms. Combining different therapies such as ET and other targeted therapies with or without chemotherapy fails to give continued benefit, unlike cyclin-dependent kinase (CDK) 4/6 inhibitors that have shown a great benefit.

Sequencing of Systemic Therapies in the Management of Advanced Prostate Cancer in India: a Delphi-Based Consensus.

Introduction: With the availability of an increasing number of therapeutic options for advanced prostate cancer (APC), optimal sequencing and combination of therapies have emerged to be the areas of challenges. In the Indian context, there is a dearth of consensus recommendations to guide clinicians regarding optimal sequencing of therapy in APC management. A Delphi-based consensus regarding optimal therapy sequencing in APC management was developed by an expert panel of medical oncologists from across India.

Overall survival in stage IV EGFR mutation‑positive NSCLC: Comparing first‑, second‑ and third‑generation EGFR‑TKIs (Review).

A substantial (40‑60%) proportion of patients with non‑small cell lung carcinoma (NSCLC) have epidermal growth factor receptor (EGFR) mutations, a crucial therapeutic target in NSCLC. Treatment strategies for patients with advanced‑stage NSCLC have markedly changed, from the empirical use of cytotoxic agents to targeted regimens. EGFR tyrosine kinase inhibitors (TKIs), the first‑line therapy for advanced NSCLC, are reported to be the most effective.

Clinical Characteristics and Outcome Trends of Adjuvant Anthracycline and Taxane Regimen for Early Stage Breast Cancer.

Background: The anthracycline and taxane-based chemotherapy treatment regimen remains the gold standard for treatment of early stage breast cancer. However, studies examining the effectiveness and use of this treatment regimen in Indian context are limited. This study examined patients treated with anthracycline and taxane-based chemotherapy at a tertiary care cancer center in India.

Expert Consensus on Effective Management of Chemotherapy-Induced Nausea and Vomiting: An Indian Perspective.

Chemotherapy-induced nausea and vomiting (CINV) is one of the most common and feared side effects in cancer patients undergoing chemotherapy. Scientific evidence proves its detrimental impact on a patient's quality of life (QoL), treatment compliance, and overall healthcare cost. Despite the CINV-management landscape witnessing a radical shift with the introduction of novel, receptor-targeting antiemetic agents, this side effect remains a chink in the armor of a treating oncologist.

Bilateral Tonsillar Enlargement as a First Manifestation of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma with an Unusual Interfollicular Pattern of Infiltration.

Tonsillar lymphoma usually presents as unilateral or bilateral enlargement or as an ulcerative or fungating lesions. Most lymphomas that involve the tonsils are diffuse large B-cell lymphomas and primary low grade lymphomas are exceptional. We report a case of primary B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) affecting tonsils with interfollicular pattern of infiltration in a 54-year-old female who clinically presented with bilateral tonsillar enlargement, sore throat, dysphagia and respiratory difficulty, unresponsive to the conservative treatment.

Paclitaxel injection concentrate for nanodispersion versus nab-paclitaxel in women with metastatic breast cancer: a multicenter, randomized, comparative phase II/III study.

Paclitaxel is widely used in the treatment of patients with metastatic breast cancer (MBC). Formulations of paclitaxel contain surfactants and solvents or albumin derived from human blood. The use of co-solvents such as polyoxyethylated castor oil is thought to contribute to toxicity profile and hypersensitivity reactions as well as leaching of plasticizers from polyvinyl chloride bags and infusion sets.

Acute promyelocytic leukemia presenting as pulmonary thromboembolism: Not all APLs bleed.
