BACKGROUND: The American Joint Committee on Cancer (AJCC) uses the same nodal staging system for cutaneous and mucosal squamous cell carcinoma of the head and neck in its 8th edition (AJCC 8) despite differences in the etiology, risk factors, and clinical behavior of the two diseases. This study aims to evaluate the performance of the AJCC 8 nodal staging system by direct comparison of cutaneous (cSCC) versus oral squamous cell carcinoma (oSCC) patients. METHODS: Patients with metastatic cSCC (N = 382) and oSCC (N = 325) were identified from a prospective database (years 1987-2016)...

BACKGROUND/OBJECTIVES: As the New Zealand Cancer Registry does not require mandatory reporting of non-melanoma skin cancers (NMSC), basal cell carcinomas (BCC) and squamous cell carcinomas (SCC), the clinical burden of these diseases is unknown. METHODS: A retrospective review of all patients with histopathology performed allowed us to estimate invasive BCC and SCC in the Auckland region in 2008 (population 1.44 million). RESULTS: During this period, a total of 21 236 NMSC were diagnosed among 13 996 patients, consisting of 5611 SCC lesions (26%) and 15 525 (74%) BCC...

Cutaneous squamous cell carcinoma (CSCC) is one of the most malignant tumors worldwide. We aimed to explore the molecular mechanism of this CSCC and screen feature genes that can function as the biomarker of CSCC and thus provide a theoretical basis for the pathogenesis research and development of medicine. The method of microarray data analysis was used in this study to explore the differentially expressed genes between tissues of normal specimens and tissues of patients with CSCC. Besides, functional enrichment analysis and signal pathway were performed on these genes to screen the feature genes that are closely associated with CSCC can function as the potential biomarkers of CSCC...

Findings from polymerase chain reaction-based methods have suggested a role of Felis catus papillomavirus 2 (FcaPV-2) in the development of feline cutaneous squamous cell carcinoma (SCC). However, because polymerase chain reaction cannot localize deoxyribonucleic acid or ribonucleic acid within the lesion, it is difficult to differentiate a coincidental FcaPV-2 infection and a causative association. Given that a key event in the pathogenesis of human papillomavirus-induced cancer is the expression of viral E6 and E7 oncogenes, localization of FcaPV-2 E6 and E7 transcription within neoplastic cells in feline SCCs would support a causative role for this papillomavirus...

While the majority of cutaneous squamous cell carcinomas (cSCCs) can be treated surgically, the additional work-up and treatments indicated for high-risk cSCC remain undefined. In recent years, improvements in tumor staging systems have allowed for the more accurate stratification of tumors into high- and low-risk categories. This insight, along with the publication of cSCC guidelines, brings us closer to the development of a consensus approach. The second article in this continuing medical education series addresses in question and answer format the most common questions related to advanced and high-stage cSCCs, with a simplified flowchart...

Cutaneous squamous cell carcinoma (cSCC), a malignant proliferation of cutaneous epithelium, represents 20% to 50% of skin cancers. Although the majority of cSCCs are successfully eradicated by surgical excision, a subset of cSCC possesses features associated with a higher likelihood of recurrence, metastasis, and death. The proper identification of these aggressive cSCCs can guide additional work-up and management. In the first article in this continuing medical education series, we discuss the incidence, recurrence rates, mortality rates, and risk factors associated with cSCC and review the staging systems used to stratify patients into high- and low-risk groups...

Radiation induced sarcoma is an unusual but well documented tumor. The frequency of radiation induced sarcoma of the head and neck region has been reported as 0.143%. In the literature the median interval between irradiation and development of sarcoma is 11 years. Cases of RIS with a short latent period i.e. less than four years are rare. We report a case of a 34 year-old female who developed an osteosarcoma of the scalp, over a previous craniotomy scar, three years after excision of a frontal anaplastic oligodendroglioma which had been followed by a course of 6 weeks radiotherapy (58 Gy) and 6 cycles of Temozolomide...

Alpha smooth muscle actin (SMA) belongs to the actin proteins. It is a known immunohistochemical marker for tumors of mesenchymal origin. There have been reports of expression of SMA in certain epithelial malignancies in the head and neck and genital regions. In this study, the authors report a primary cutaneous spindle cell squamous carcinoma expressing SMA. Both high- and low-molecular-weight keratins and p63 were positive, and S100 protein, SOX10, MART-1/Melan-A, and muscle-specific actin stains were negative...

Cutaneous squamous cell carcinomas (SCC) affecting the regions of the head and neck can be challenging to resect surgically and refractory to chemotherapy or radiation therapy. Consequently; the treatment of squamous cell carcinomas of the skin is a focus of current research. One such advancement is immunotherapy. Herein we describe clinical remission of invasive, poorly differentiated squamous cell carcinoma of the pre-auricular region with external auditory canal involvement using cetuximab, an epidermal growth factor receptor (EGFR) antibody; and nivolumab, a programmed death receptor-1 (PD-1) antibody...

Here we report corin, a synthetic hybrid agent derived from the class I HDAC inhibitor (entinostat) and an LSD1 inhibitor (tranylcypromine analog). Enzymologic analysis reveals that corin potently targets the CoREST complex and shows more sustained inhibition of CoREST complex HDAC activity compared with entinostat. Cell-based experiments demonstrate that corin exhibits a superior anti-proliferative profile against several melanoma lines and cutaneous squamous cell carcinoma lines compared to its parent monofunctional inhibitors but is less toxic to melanocytes and keratinocytes...

Cutaneous squamous cell carcinoma (CSCC) is the second most common type of skin cancer with increasing incidence. In recent years, several microRNAs (miRs) have been demonstrated to serve an oncogenic or tumor suppressive role in CSCC. However, the exact role of miR-34a in CSCC and the underlying regulatory mechanism remain unclear. The present study aimed to investigate the regulatory mechanism of miR-34a in the malignant phenotypes of CSCC cells using MTT assay, wound healing assay and transwell assay. It was observed that miR-34a was significantly downregulated in CSCC tissues and cell lines, and low miR-34a expression was associated with the aggressive progression of CSCC...
