HOXA10 belongs to the homeobox gene family and is essential for uterine biogenesis, endometrial receptivity, embryo implantation, and stromal cell decidualization. Available evidence suggests that the expression of HOXA10 is dysregulated in different endometrial disorders like endometrial hyperplasia, endometrial cancer, adenomyosis, endometriosis, recurrent implantation failure, and unexplained infertility. The downregulation of HOXA10 occurs by genetic changes in the HOXA10 gene, methylation of the HOXA10 locus, or selected miRNAs. Endocrine disruptors and organic pollutants also cause the reduced expression of HOXA10 in these conditions. In vivo experiments in mouse models and in vitro studies in human cell lines demonstrate that downregulation of HOXA10 leads to endometrial epithelial cell proliferation, failure of stromal cell decidualization, altered expression of genes involved in cell cycle regulation, immunomodulation, and various signaling pathways. These disruptions are speculated to cause infertility associated with the disorders of the endometrium.

The combination of targeted therapies and immunotherapies for advanced and metastatic sarcomas has been proposed owing to the enhanced effect of antiangiogenic therapies on the tumor microenvironment. We found eight studies published to date assessing the effectiveness of combined multitargeted vascular endothelial growth factor (VEGF)-tyrosine kinase inhibitors with immune checkpoint inhibitors (ICIs) in sarcoma. It is difficult to draw conclusions owing to limited data and primarily single-arm studies, although initial literature appears promising and requires further study.

Evaluation of tumor infiltrating lymphocytes as recommended by current guidelines is largely based on stromal regions within the tumor. In the context of epithelial malignancies, the epithelial region and the epithelial-stromal interface are not assessed, because of technical difficulties in manually discerning lymphocytes when admixed with epithelial tumor cells. The inability to quantify immune cells in epithelial-associated areas may negatively impact evaluation of patient response to immune checkpoint therapies.

Furthermore, it explores the impact of immune cell imbalance, abnormal cytokine levels, and stromal cell impairment on disease progression and prognosis. Additionally, the review analyzes the immune mechanisms underlying the transformation of high-risk MDS to AML.

Background: Melanoma is one of the most immunogenic malignancies, yet resistance to immune checkpoint inhibitors (ICIs) remains a major obstacle to durable therapeutic success. Emerging evidence indicates that aging-related processes, including cellular senescence and immunosenescence, can reshape the tumor microenvironment (TME) to favor immune evasion and disease progression. Senescent melanoma and stromal cells secrete a senescence-associated secretory phenotype (SASP) that alters immune cell recruitment and function, while immunosenescence leads to diminished cytotoxic responses and the accumulation of dysfunctional or suppressive immune subsets.

Lung adenocarcinoma (LUAD) associated with usual interstitial pneumonia (UIP) harbours distinct features compared to lung adenocarcinoma without UIP. Therefore, we aimed to characterise the tumour microenvironment of LUAD with UIP by focusing on cancer-associated fibroblasts (CAFs) and stromal composition. Immunohistochemistry was performed on 32 LUAD samples (16 each with and without UIP) to evaluate CAF marker expression and lymphocyte infiltration.
