Prognostic and predictive biomarkers in head and neck cancer: something old, something new, something borrowed, something blue and a sixpence in your shoe. Pathology 2024; 56:170-185. [PMID: 38218691 DOI: 10.1016/j.pathol.2023.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 11/26/2023] [Accepted: 11/28/2023] [Indexed: 01/15/2024]
Abstract
A biomarker is a measurable indicator of biological or pathological processes or the response to an exposure or intervention and is used to guide management decisions. In head and neck pathology, biomarkers are assessed by histological criteria and immunohistochemical and molecular studies. Surgical resection remains the mainstay of management of many head and neck malignancies. Adjuvant radiotherapy and/or systemic therapy may be administered depending on the presence of adverse prognostic factors identified on histopathological or immunohistochemical examination. In this review, we outline the clinically relevant prognostic and predictive factors in head and neck malignancies including conventionally recognised factors such as tumour size, depth of invasion, lymphovascular and perineural invasion and margin status as well as novel evolving factors such as recurrent genetic rearrangements and assessment of immune checkpoints. Practical issues are discussed to assist with recognising and reporting of these factors. A summary of useful tools such as structured pathology report formats is also included to assist with comprehensive reporting of all clinically relevant parameters, minimise risk and improve workflow efficiencies.

Abstract
Basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) are the most frequently occurring non-melanocytic skin cancers. The objective of our study is to present the pathophysiology of BCC and cSCC and its direct relationship with the histopathological diagnostics and the differential diagnostics of these types of cancer, based on the morphological characteristics, immunohistochemical profile, and genetic alterations. The qualitative study was based on emphasizing the morphological characteristics and immunohistochemistry profiles of BCC and cSCC and the differential diagnostics based on the tissue samples from the Clinical Pathology Department of Mures Clinical County Hospital between 2020 and 2022. We analyzed the histopathological appearances and immunohistochemical profiles of BCC and cSCC in comparison with those of Bowen disease, keratoacanthoma, hyperkeratotic squamous papilloma, metatypical carcinoma, pilomatricoma, trichoblastoma, Merkel cell carcinoma, pleomorphic dermal sarcoma (PDS), and melanoma. Our study showed the importance of the correct histopathological diagnosis, which has a direct impact on the appropriate treatment and outcome for each patient. The study highlighted the histopathological and morphological characteristics of NMSCs and the precursor lesions in HE and the immunohistochemical profile for lesions that may make the differential diagnosis difficult to establish.

Abstract
ABSTRACT Studies on the relationship between stathmin 1 (STMN1) and cutaneous squamous cell carcinoma (cSCC) are limited. We aimed to evaluate the relationship between clinicopathological factors and STMN1 and p53 expressions in cSCC and compare them with those in the precursor lesions of cSCC and normal tissue. A total of 195 patients, followed between January 2014 and December 2021, with diagnoses of primary cSCC (n = 129), in situ cSCC (n = 20), or actinic keratosis (n = 46), as well as 29 histopathologically normal tissue samples, were included in the study. Immunohistochemical staining for STMN1 and p53 was performed. In the cSCC group, STMN1 scores were higher in poorly differentiated ( P = 0.001) and ulcerated ( P < 0.001) tumors. A linear relationship between STMN1 score and tumor area, tumor thickness, and mitosis was found ( P = 0.001, P = 0.003, and P < 0.001, respectively). There was no statistically significant correlation between STMN1 and p53 scores. Our results support the previous view that STMN1 may be associated with some adverse clinicopathological and high-risk features of cSCC. To the best of our knowledge, this is the first and largest study to investigate STMN1 expression in cSCC, precancerous lesions of cSCC, and normal tissues.

Factors for risk stratification of patients with actinic keratosis using integrated analysis of clinicopathological features and gene expression patterns. Australas J Dermatol 2023; 64:80-91.

Abstract
BACKGROUND Actinic keratosis (AK) is considered as precursor lesion of invasive squamous cell carcinoma. Molecular studies on AK are limited because of too small size of the biopsy specimen to obtain enough DNA or RNA. METHODS Twenty biopsy cases of AK, followed by second same-sited biopsies, were included. Ten cases were diagnosed with total regression (regression group), while the other 10 were diagnosed with invasive carcinoma (progression group) in the follow-up biopsies. Using digital spatial profiling (DSP) technology, whole-gene expression analysis defined by specific regions of interest was performed for all 20 cases. After the clinicopathological features were assessed, separate and integrated analyses of these features and gene expression patterns were performed using machine-learning technology. All analyses were performed on both lesion keratinocytes (KT) and infiltrated stromal lymphocytes (LC). RESULTS Among the 18,667 genes assessed, 33 and 72 differentially expressed genes (DEGs) between the regression and progression groups were found in KT and LC respectively. The primary genes distinguishing the two groups were KRT10 for KT and CARD18 for LC. Clinicopathological features were weaker in risk stratification of AK progression than the gene expression patterns. Pathways associated with various cancers were upregulated in the progression group of KT, whereas the nucleotide-binding oligomerization domain (NOD)-like receptor signalling pathway was upregulated in the progression of LC. CONCLUSION Gene expression patterns were effective for risk stratification of AK progression, and their distinguishing power was higher than that of clinicopathological features.

Abstract
CD47 is a cell surface molecule and regulates diverse cellular responses. CD47 is highly expressed in cancer cells and has potential as a therapeutic target and prognostic factor in cancer patients. The expression patterns of CD47 in basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and its precursor lesions, and its clinicopathological significance were investigated. CD47 expression was evaluated by immunohistochemistry in 152 cases of BCC and 71 cases of SCC. For comparison of CD47 expression, actinic keratosis (AK), squamous cell carcinoma in situ (SCCIS), keratoacanthoma (KA), and normal skin (NS) tissue were used. CD47 expression in BCC was significantly lower than that of SCC (p < 0.001). CD47 expression levels in SCC and KA were significantly higher than those of NS and AK (p < 0.05). High CD47 expression was significantly associated with the presence of ulceration (p = 0.005) and a deeper level of invasion (p = 0.011) in BCC. In addition, high CD47 expression was significantly associated with the presence of ulceration (p = 0.019) and larger tumor size (p = 0.004) in SCC. CD47 expression was associated with tumorigenesis and tumor progression in non-melanoma skin cancers.

Abstract
Cutaneous squamous cell carcinoma (CSCC) is a common malignant skin cancer with a significant impact on health, and it is important to determine the degree of reliance of CSCC on angiogenesis for growth and metastasis. Major regulators of angiogenesis are the vascular endothelial growth factor (VEGF) family and their associated receptors. Alternative pre-mRNA splicing produces multiple isoforms of VEGF-A and PLGF with distinct biological properties. Several studies highlight the function of VEGF-A in CSCC, but there are no studies of the different isoforms of VEGF-A and PLGF for this neoplasm. We characterized the expression of three isoforms of VEGF-A, two isoforms of PLGF, and their receptors in cat CSCC biopsies compared to normal haired skin (NHS). Although our results revealed no significant changes in transcript levels of panVEGF-A or their isoforms, the mRNA levels of PLGF I and the receptors Flt-1 and KDR were downregulated in CSCC compared to NHS. Differences were observed in ligand:receptor mRNA expression ratio, with the expression of VEGF-A relative to its receptor KDR higher in CSCC, which is consistent with our hypothesis and prior human SCC studies. Immunolocalization in tissue showed increased expression of all measured factors and receptors in tumor cells compared to NHS and surrounding vasculature. We conclude that the factors measured may play a pivotal role in CSCC growth, although further studies are needed to clarify the role of angiogenic factors in feline CSCC.

Abstract
INTRODUCTION Near-Infrared Photoimmunotherapy (NIR-PIT) is a novel molecularly targeted phototherapy. This technique is based on a conjugate of a near-infrared photo-inducible molecule (antibody-photon absorber conjugate, APC) and a monoclonal antibody that targets a tumor-specific antigen. To date, this novel approach has been successfully applied to several types of cancer. AREAS COVERED The authors discuss the possible use of NIR-PIT for the management of skin diseases, with special attention given to squamous cell carcinomas, advanced melanomas, and primary cutaneous lymphomas. EXPERT OPINION NIR-PIT may be an attractive strategy for the treatment of skin disorders. The main advantage of NIR-PIT therapy is its low toxicity to healthy tissues. Cutaneous lymphocyte antigen is a potential molecular target for NIR-PIT for both cutaneous T-cell lymphomas and inflammatory skin disorders.

Abstract
Cutaneous squamous cell carcinoma (cSCC) is a highly prevalent cancer and the majority of cSCC have a good prognosis. However, a subset of cSCC can progress to advanced disease. We present the first reported case of a giant cSCC located on the breast. In addition, a systematic literature search on extra-anogenital giant (EAG) cSCC was performed using Pubmed and MEDLINE databases. Thirty-one articles could be retained which were relevant for this review. A total of 42 well-described cases were identified. Median age at presentation was 70 years (range 9-100 years). Twenty-four (57%) patients were male, eighteen were female (43%). The estimated median delay of treatment was 12 months (range 1 to >240 months). In 27 patients (64%) the giant cSCC was localized on the neck, face or scalp, 6 on the thoracic wall or back (14%), 4 on the lower limb (10%), 2 on the hip or buttock (5%), 2 on the upper limb (5%), one (2%) on the breast. Tumor stage at presentation was T2, T3 and T4 in respectively 26 (62%), 11 (26%) and 5 (12%) cases. Lymph node metastases were identified in 1 patient (2%) and distant metastases in another patient (2%). In 34 out of 42 cases (81%) primary radical surgical excision was performed, 3 received radiotherapy, 2 chemotherapy and 3 palliative care. In the cases with reported follow-up, four patients (4/30: 13%) died of disease. The treatment of EAG cSCC poses many problems, making a multidisciplinary approach of paramount importance.

Circular RNA profiles and the potential involvement of down-expression of hsa_circ_0001360 in cutaneous squamous cell carcinogenesis. FEBS Open Bio 2021; 11:1209-1222.

Abstract
Circular RNAs (circRNAs) act as sponges of noncoding RNAs and have been implicated in many pathophysiological processes, including tumor development and progression. However, their roles in cutaneous squamous cell carcinoma (cSCC) are not yet well understood. This study aimed to identify differentially expressed circRNAs and their potential functions in cutaneous squamous cell carcinogenesis. The expression profiles of circRNAs in three paired cSCC and adjacent nontumorous tissues were detected with RNA sequencing and bioinformatics analysis. The candidate circRNAs were validated by PCR, Sanger sequencing and quantitative RT‐PCR in another five matched samples. The biological functions of circRNAs in SCL‐1 cells were assessed using circRNA silencing and overexpression, 3‐(4,5‐dimethylthiazol‐2‐yl)‐5‐(3‐carboxymethoxyphenyl)‐2‐(4‐sulfophenyl)‐2H‐tetrazolium inner salt (MTS), flow cytometry, transwell and colony formation assays. In addition, the circRNA–miRNA–mRNA interaction networks were predicted by bioinformatics. In summary, 1115 circRNAs, including 457 up‐regulated and 658 down‐regulated circRNAs (fold change ≥ 2 and P < 0.05), were differentially expressed in cSCC compared with adjacent nontumorous tissues. Of four selected circRNAs, two circRNAs (hsa_circ_0000932 and hsa_circ_0001360) were confirmed to be significantly decreased in cSCC using PCR, Sanger sequencing and quantitative RT‐PCR. Furthermore, hsa_circ_0001360 silencing was found to result in a significant increase of the proliferation, migration and invasion but a significant decrease of apoptosis in SCL‐1 cells in vitro, whereas hsa_circ_0001360 overexpression showed the opposite regulatory effects. hsa_circ_0001360 was predicted to interact with five miRNAs and their corresponding genes. In conclusion, circRNA dysregulation may play a critical role in carcinogenesis of cSCC, and hsa_circ_0001360 may have potential as a biomarker for cSCC.

Despite the overall excellent survival rates in patients affected by early cutaneous squamous cell carcinoma (CSCC), advanced forms of CSCC are associated with high patient mortality. To date, only limited therapeutic modalities have been implemented, including chemotherapy and radiotherapy. Systemic therapy was enriched by the addition of epidermal growth factor receptor inhibitors (EGFRi) in the last years. Unfortunately, the overall outcome of all these therapeutic strategies remains poor, therefore important unmet clinical needs persist. Thanks to a better understanding of the biology of advanced CSCC, new treatment options are now available. This article presents the current definition of advanced CSCC along with actual therapeutic options and discusses the strengths and limitations of a new promising systemic approach, which involves the use of immune checkpoint inhibitors.

Abstract
BACKGROUND SOX18 is an integral transcription factor that is involved in endothelial cells differentiation during both angiogenesis and lymphangiogenesis. Therefore, it has been implicated in tumor progression and metastasis. OBJECTIVE To study SOX18 expression in nonmelanoma skin cancers (NMSCs) in comparison to seborrheic keratosis (SK) and normal control skin, and to assess its probable role in tumor evolution and progression. PATIENTS AND METHODS This study was conducted on 60 specimens of NMSCs: 30 basal cell carcinomas (BCC) and 30 squamous cell carcinomas (SCC), 30 specimens of SK, and 30 normal skin specimens. All were examined for immunohistochemical expression of SOX18 antibody. Additionally, morphometric assessment of vessel density (blood & lymphatic) in each specimen was estimated. RESULTS Significant SOX18 overexpression was observed in all studied cutaneous tumors in comparison to control skin. The highest score of SOX18 expression was detected in SCC, then BCC, and the least expression was reported in SK with significant difference between them. Furthermore, significant upregulation of SOX18 expression was observed in high-risk types of both BCC and SCC compared to low-risk types. Stromal vessel density showed significant differences between the studied tumors with the highest mean value in SCC, followed by BCC and then SK. Positive correlation between SOX18 expression in the studied tumors and their vessel density was detected. CONCLUSIONS SOX18 may have a potential role in the evolution as well as progression of NMSCs, possibly through induction of both angiogenesis and lymphangiogenesis. Furthermore, it could be beneficial for prediction of NMSC patients with poor prognosis.
