Introduction: Tobacco consumption is a leading cause of mortality globally. Eighty percent of these deaths occur in low- and middle-income countries (LMICs). Despite this, there is a large treatment gap due to both demand and supply-side barriers.

Introduction: Peripheral blood mononuclear cells (PBMCs) trafficking is regulated by chemokines, which modulate leukocyte migration toward tumors and may collaborate in the efficacy of immunotherapy. In our study, we investigated whether the CXCL12/CXCR4 axis plays a role in the efficacy of immunotherapy in non-small cell lung cancer (NSCLC) by analyzing CXCR4 expression for CXCR4 in peripheral blood (PB), and the expression of its ligand CXCL12 in tumor.

Methods: We identified PBMCs expressing CXCR4 using flow cytometry in a prospective cohort of NSCLC patients before starting anti-PD-1 immunotherapy.

Article Synopsis
  • - Tumor immune microenvironment (TIME) significantly influences how prostate cancer (PC) responds to treatments and understanding mechanisms of resistance is crucial.
  • - Research indicates that certain genomic changes, like microsatellite instability (MSI) and CDK12 bi-allelic loss, may increase response rates to immune therapies, but patient responses vary widely.
  • - The review explores how immune cell interactions within tumors affect PC progression, how standard therapies impact immune responses, and the challenges in analyzing the immune landscape related to tumors.

The COVID-19 pandemic in Italy is a stark reminder of the necessity of incorporating the social, economic, and political context in planning responses to public health emergencies. During the ongoing global COVID-19 crisis, it is not just crucial but a shared responsibility to supplement epidemiological approaches with insights from the social sciences. This ensures effective and equitable policies, and it is a responsibility that each of us in the field shares.

Atypical cellular neurothekeoma is a rare benign soft-tissue tumour that usually arises in the head and neck region, shoulder girdles, and proximal extremities, predominantly in young women. This dermal neoplasm is under-reported in the literature and is not uncommonly misdiagnosed as a malignant tumour due to its worrisome histologic characteristics. Currently, the diagnosis of cellular neurothekeoma relies on a panel of non-specific immunohistochemical markers and its etiopathogenesis is unknown.
