We hypothesize that this reaction was triggered by azathioprine dose reduction. Dose modification of long-term immunosuppressive medications in patients with a transplantation history who later develop SCCs warrants further investigation.
Mesenchymal features were associated with a higher metastatic capacity and anoikis resistance, yet this comes with a sensitivity toward TNF-induced cell death. Altogether we provide insights in cSCC heterogeneity and modes to target mesenchymal-metastasis inducing cells.

We generated tamoxifen inducible Dab2 conditional knockout system for our study...In patients, TCGA data analysis of skin cancer melanoma (SKCM) showed a trend where high levels of Dab2 correlated with poor overall survival. The present study shows that Dab2 promotes tumour progression in skin SCC.

Notably, our study showed that proteomes sampled with e-biopsy from cSCC and BCC lesions are different and that proteins of CRNN, SULT1E1, and ITPK1 genes are significantly overexpressed in BCC in comparison with those in cSCC. Our results provide evidence that the e-biopsy approach could potentially be used as a tool to support cutaneous lesions classification with molecular pathology.
Overall, muSCC shows similar genomic alterations and TMB to HPV(–) vSCCs. CGP of inflammation-associated SCCs may be important to more fully inform therapeutic options and stratification in clinical trials.
Cemiplimab is a safe and effective therapy, particularly in elderly patients. Well-differentiated tumors with low proliferative index, intratumoral inflammatory infiltrate, and tumor necrosis may predict better clinical response.
Following initiation of standard chemotherapy agents, carboplatin and paclitaxel, the patient developed a diffuse, itchy rash over her abdomen, back, and bilateral upper and lower extremities. Biopsy of the rash revealed a diffuse non-resectable cutaneous squamous cell skin carcinoma (cSCC) in situ. Consequently, a PD1-inhibitor was added to her neoadjuvant chemotherapy regimen, which resulted in complete response to both metastatic ovarian and diffuse cSCC in situ at time of surgery.
In conclusion, we have identified CCNA2, CCNB2, and UBE2C as novel biomarkers for cSCC, and the NEAT1/H19-hsa-miR-148a-3p-CCNA2 and NEAT1-hsa-miR-140-3p-UBE2C ceRNA networks may represent molecular mechanisms under-lying cSCC progression. The findings of this study offer new diagnostic and therapeutic options for cSCC patients.
This review will provide an overview of our current understanding of FGFR2 and potential mechanisms in which we can target FGFR2 in cSCC. The goals of this review are the following: (1) to highlight our current knowledge of the role of FGFR2 in healthy skin and contrast this with its role in the development of cancer; (2) to further explain the specific molecular mechanisms that FGFR2 uses to promote tumorigenesis; (3) to describe how FGFR2 contributes to more invasive disease; (4) to describe its immunosuppressive effects in skin; and (5) to evaluate its effect on current anticancer therapy and discuss therapies on the horizon to target FGFR2 related malignancy.
Among these, we further validated LINC00704 and LINC01116 as proliferation-regulating lncRNAs in cSCC lines and potential biomarkers of cSCC progression. Taken together, our study provides a comprehensive signature of lncRNAs with roles in regulating cSCC progression.
In contrast, the SKH-hr1 mice were found to be the least suitable, even though they are albino. Notably, proteasome analysis revealed a potential role of proteasome activity in squamous cell carcinogenesis.
This may be the signature of genuine parotid primary SCC, but metastasis from an SCC from another organ cannot be excluded. Accordingly, a diagnosis of primary parotid gland SCC should be viewed with skepticism.

Loss of MCPIP1 modulates the expression profiles of 33 miRNAs in chemically induced Mcpip1eKO papillomas, and these changes directly affect the miRNA‒mRNA network and the modulation of pathways and processes related to carcinogenesis.
A patient with metastatic cutaneous squamous cell carcinoma developed a severe hypersensitivity reaction to pembrolizumab and subsequently to cemiplimab, despite premedication.
Knockdown of TROP2 also resulted in decreased expression of vimentin, along with reduced migratory capacity. These findings suggest that TROP2 plays a crucial role in cSCC cell proliferation and migration, and highlight the potential of sacituzumab govitecan as a promising therapeutic option for cSCC.

Overall, the results show that CAP may improve the anti-tumor effects of conventional ALA-PDT on SCC cells. Whether this combined application is successful in treating AK in vivo has to be carefully examined in follow-up studies.
This study is the first to report and characterize NETs in NMSC. Thus, it gives an incentive for further research in this relevant yet understudied topic.
In conclusion, this study developed a new immunotherapeutic strategy for treating mCSCC. However, further research is needed to fully comprehend the mechanism of this serum treatment.

Emerging strategies targeting these immune elements, such as monoclonal antibodies, are also discussed for their potential to enhance anti-tumor immune responses and improve clinical outcomes. By elucidating the immunological landscape of BCC and cSCC and drawing comparisons to melanoma, this review highlights the transformative potential of immunotherapy in treating these malignancies.
And it was validated in clinical samples from different patients. Our findings reveal the dynamic immnue homeostasis from normal skin to cSCC tissue, this alteration might drive HPV-induced cSCC.

P=NA | N=954 | "The data will be shared in an oral presentation at the American Society for Radiation Oncology (ASTRO) 2024 Annual Meeting....Patients with T1 tumors had similar metastasis-free survival (MFS) rates regardless of immune status yet were further stratified by their DecisionDx-SCC test result (3-year MFS: Class 1 test result: 96.9% vs. Class 2A/2B test result: 88.6%, p<0.001). Immune suppressed patients with T2a tumors had significantly worse MFS than immune competent patients with T2a tumors (71.4% vs. 91.2%, p<0.001). DecisionDx-SCC further stratified immune suppressed patients with T2a tumors into those with more favorable (Class 1 test result; 3-yr MFS of 83%) and less favorable survival (Class 2A/2B test result; 3-yr MFS of 57%)."
The patient successfully underwent Mohs surgery, and pathology was notable for positive perineural invasion of large caliber nerves. This case highlights the potential of the 40-gene expression profile as an independent predictor in assessing metastatic risk compared to traditional staging methods.
