Targeting the tumor microenvironment: Potential strategy for cancer therapeutics

Cellular and stromal components including tumor cells, immune cells, mesenchymal cells, cancer-linked fibroblasts, and extracellular matrix, constituent tumor microenvironment (TME). TME plays a crucial role in reprogramming tumor initiation, uncontrolled proliferation, invasion and metastasis as well as response to therapeutic modalities. In recent years targeting the TME has developed as a potential strategy for treatment of cancer because of its life-threatening functions in restricting tumor development and modulating responses to standard-of-care medicines. Cold atmospheric plasma, oncolytic viral therapy, bacterial therapy, nano-vaccine, and repurposed pharmaceuticals with combination therapy, antiangiogenic drugs, and immunotherapies are among the most effective therapies directed by TME that have either been clinically authorized or are currently being studied. This article discusses above-mentioned therapies in light of targeting TME. We also cover problems related to the TME-targeted therapies, as well as future insights and practical uses in this rapidly growing field.

Promise of dostarlimab in cancer therapy: Advancements and cross-talk considerations

In recent years, immunotherapy for cancer treatment using monoclonal antibodies has shown clinical success, particularly with programmed cell death protein 1 (PD-1) and its ligand programmed death-ligand 1 (PD-L1). Dostarlimab, an immune checkpoint inhibitor, interacts with adaptive immunity by binding to human PD-1, inhibiting PD-L1 and PD-L2 interactions, and cross-talk with adaptive immunity. Recent clinical trials have shown that dostarlimab is effective in treating mismatch repair deficiency (dMMR) in endometrial cancer patients, leading to its approval in the United States and the European Union in 2021. This article provides a comprehensive overview of dostarlimab, its therapeutic ability, and the different indications for which it is being used. Dostarlimab could serve as a potential alternative to many cancer treatments that frequently have severe consequences on patients' quality of life. Teaser The comprehensive story behind dostarlimab is how it cured all 18 cancer patients who took part in the experimental clinical trial, ultimately leading to its approval by the US FDA.

Therapeutic Targets In Breast Cancer Signaling: A Review

For women, the most dominant type of cancer is breast cancer and perhaps one of the most recognizedreasons of death. This is a disorder of many distinct traits, many of which are known as positive hormone receptor, human epidermal receptor-2 (HER2+), and three negative breast cancers (TNBC). Drugs that directly target and kill tumors constitute a rapidly-growing form of molecular therapy for cancer patients. Analysis reveals that stable breast tissue cells exhibit receptors which aren't usually present. As a result, it is imperative to cognize the molecular roots of breast cancer and the myriad compromised pathology-related processes and pathways to ensure progresses in early diagnosis and prevention. This study demonstrates essential cellular pathways relevant for breast cancer including improvements in cell proliferation, apoptosis, and hormone balances in breast tissues. On the basis of these notions, we consider how breast cancer is associated to the creation of potentially therapeutic interventions and predictive biomarkers.

Metastasis Relapse in Synovial Sarcoma of Parotid Gland Followed by Neuropathies and Tissue Damage: A Case Report

Synovial sarcomas are a heterogeneous group of tumors, accounting for 1-2% of adult cancers worldwide. Formation of synovial sarcoma after tissue and nerve injury, radiations induced neuropathies and latent metastasis is those events which are still controversial and need more research. In this report, we present the case of an 18-year-old female patient who developed synovial sarcoma followed by a punch to the face. MRI showed lobulated lesion of 4x3cm appreciated in left parotid space. In spite of Parotidectomy, radiotherapy and radiosurgery followed by MRI and CT-scan latent metastasis was raised in lungs which leads to demise of patient. There are numerous potential etiologic and neurological factors for the development of latent metastasis in synovial sarcoma. Here we will summarize all factors and its complications according to the current literature.

Novel therapeutic drug strategies to tackle immune-oncological challenges faced by cancer patients during COVID-19

INTRODUCTION

For the clinical treatment of cancer patients, coronavirus (SARS-CoV-2) can cause serious immune-related problems. Cancer patients, who experience immunosuppression due to the pathogenesis and severity of disease, may become more aggressive due to multiple factors such as age, comorbidities, and immunosuppression. In this pandemic era, COVID-19 causes lymphopenia, cancer cell awakening, inflammatory diseases, and a cytokine storm that worsens disease-related morbidity and prognosis.

AREAS COVERED

We discuss all the risk factors of COVID-19 associated with cancer patients and propose new strategies to use antiviral and anticancer drugs for therapeutic purposes. We bring new drugs, cancers and COVID-19 treatment strategies together to address the immune system challenges faced by oncologists.

EXPERT OPINION

The chronic inflammatory microenvironment caused by COVID-19 awakens dormant cancer cells through inflammation and autoimmune activation. Drug-related strategies to ensure that clinical treatment can reduce the susceptibility of cancer patients to COVID-19, and possible counter-measures to minimize the harm caused by the COVID-19 have been outlined. The response to the pandemic and recovery has been elaborated, which can provide information for long-term cancer treatment and speed up the optimization process.

An Update on Transfusion Related Immunomodulation (TRIM) in a Time of COVID- 19 Pandemic

Recipients' immune systems are triggered by blood and blood component therapy. Transfusion-related immunomodulation (TRIM) is a complicated immunological response to transfusion that results in immunosuppression. The mechanisms of TRIM include the presence of residual white blood cells and apoptotic cells, the infusion of immunosuppressive cytokines that are present in donor components or that occur during blood processing, the transfer of metabolically active growth factor-loaded particles and extracellular vesicles, and the presence of hemoglobin or extracellular vesicles binds to hemoglobin. TRIM variables include donor-specific factors and processing variables. TRIM can explain, at least partially, the controversial negative clinical results observed in patients with covid19. Many potential treatment methods have been used in clinical practice, including supportive interventions, immunomodulators, antiviral therapy, and infusion of convalescent plasma. Here, we summarize current potential treatments for COVID-19 infection-related diseases and discuss the clinical value of blood transfusion-related technologies for COVID-19 treatment in blood transfusion-related immune regulation.

Pulmonary Embolism in Covid-19 Pandemic: A Threat to Recovery of the Infected Patients

Severe Acute Respiratory Syndrome Coronavirus 2 is a new type of coronavirus that can cause Coronavirus Disease 2019 (Covid-19) and is associated with an increased risk of thrombosis-related pulmonary embolism. Globally, doctors have revised their management strategies for suspected and confirmed PD in patients with Coronavirus disease (Covid-19) in 2019. Choosing the right drug and the right dose requires consideration of potential comorbidities, which can be explained by the direct and indirect pathological consequences of Covid-19, complement activation, cytokine release, endothelial dysfunction, and the interaction between different types of blood cells. Discuss the pathophysiological events, therapeutic mortality strategies, risk factors and clinical management of patients with Covid-19 pulmonary embolism.
