Effect of Liquid Blood Concentrates on Cell Proliferation and Cell Cycle- and Apoptosis-Related Gene Expressions in Nonmelanoma Skin Cancer Cells: A Comparative In Vitro Study.

Nonmelanoma skin cancer (NMSC) presents a significant challenge to global healthcare due to its rising incidence, prompting the search for innovative treatments to overcome the limitations of current therapies. Our study aims to explore the potential effects of the liquid blood concentrate platelet-rich fibrin (PRF) on basal cell carcinoma cells (BCCs) and squamous cell carcinoma cells (SCCs) in order to obtain results that may lead to new possible adjunctive therapies for managing localized skin cancers, particularly NMSC. Basal cell carcinoma (BCC) cells and squamous cell carcinoma (SCC) cells were indirectly treated with PRF generated via different relative centrifugation forces, namely high and low RCF PRF, for 7 days.

The Impact of Socioeconomic Status and Comorbidities on Non-Melanoma Skin Cancer Recurrence After Image-Guided Superficial Radiation Therapy.

Background: Non-melanoma skin cancers (NMSCs) are the most common cancers in the United States. Image-guided superficial radiation therapy (IGSRT) is an effective treatment for NMSCs. Patient comorbidities and socioeconomic status (SES) are known contributors to health disparities.

Characterization of Somatostatin Receptor 2 Gene Expression and Immune Landscape in Sinonasal Malignancies.

Olfactory neuroblastoma (ONB), sinonasal undifferentiated carcinoma (SNUC), and sinonasal neuroendocrine carcinoma (SNEC) are rare malignancies arising from the sinonasal tract with limited therapeutic options. The expression of the somatostatin receptor 2 gene (), which is expressed in other neuroendocrine neoplasms and is therapeutically actionable, has been reported in these tumors. Here, we analyzed gene expression and its associations with genomic features, established biomarkers predicting of immune response, and the tumor immune microenvironment in a cohort of ONB, SNUC, and SNEC tumor samples (26, 13, and 8 samples, respectively) from a real-world database.

The Role of Radiation, Immunotherapy, and Chemotherapy in the Management of Locally Advanced or Metastatic Cutaneous Malignancies.

Introduction: Skin cancer impacts a significant proportion of the population. While surgical management is often the mainstay of treatment, advanced or metastatic cutaneous malignancies require additional local and/or systemic therapies.

Methods: A review of the literature was performed studying the use of radiation therapy, chemotherapy, and immunotherapy for locally advanced or metastatic cutaneous malignancies.

Patients with Darier disease have an increased risk of keratinocyte carcinoma: a Swedish registry-based nationwide cohort study.

Background: Darier disease is a genodermatosis which manifests as hyperkeratotic papules and superficial erosions mainly in seborrheic skin areas. This retrospective registry-based cohort study aimed to estimate the association between Darier disease and skin cancer.

Results: Patients diagnosed with Darier disease were identified from the patient registry of Sahlgrenska University Hospital (Gothenburg, Sweden) in 2016-2020.

Detection of genome instability by 53BP1 expression as a long-lasting health effect in human epidermis surrounding radiation-induced skin cancers.

We previously reported endogenous activation of the DNA damage response (DDR) in the epidermis surrounding basal cell carcinoma resected from Nagasaki atomic bomb survivors, suggesting the presence of genomic instability (GIN) in the survivors as a late effect of radiation. Dual-color immunofluorescence (IF) analysis of TP53-binding protein-1 (53BP1) and a proliferative indicator, Ki-67, to elucidate GIN in tumor tissues revealed that abnormal 53BP1 expression is closely associated with carcinogenesis in several organs. The present study aimed to confirm the presence of radiation-induced GIN in the non-neoplastic epidermis of patients with radiation-induced skin cancer.
