Abstract
Introduction Basal cell carcinoma (BCC) is the most common skin cancer, lacking reliable biomarkers or therapeutic targets for effective treatment. Genome-wide association studies (GWAS) can aid in identifying drug targets, repurposing existing drugs, predicting clinical trial side effects, and reclassifying patients in clinical utility. Hence, the present study investigates the association between plasma proteins and skin cancer to identify effective biomarkers and therapeutic targets for BCC. Methods Proteome-wide mendelian randomization was performed using inverse-variance-weight and Wald Ratio methods, leveraging 1 Mb cis protein quantitative trait loci (cis-pQTLs) in the UK Biobank Pharma Proteomics Project (UKB-PPP) and the deCODE Health Study, to determine the causal relationship between plasma proteins and skin cancer and its subtypes in the FinnGen R10 study and the SAIGE database of Lee lab. Significant association with skin cancer and its subtypes was defined as a false discovery rate (FDR) < 0.05. pQTL to GWAS colocalization analysis was executed using a Bayesian model to evaluate five exclusive hypotheses. Strong colocalization evidence was defined as a posterior probability for shared causal variants (PP.H4) of ≥0.85. Mendelian randomization-Phenome-wide association studies (MR-PheWAS) were used to evaluate potential biomarkers and therapeutic targets for skin cancer and its subtypes within a phenome-wide human disease category. Results PTGES2, RNASET2, SF3B4, STX8, ENO2, and HS3ST3B1 (besides RNASET2, five other plasma proteins were previously unknown in expression quantitative trait loci (eQTL) and methylation quantitative trait loci (mQTL)) were significantly associated with BCC after FDR correction in the UKB-PPP and deCODE studies. Reverse MR showed no association between BCC and these proteins. PTGES2 and RNASET2 exhibited strong evidence of colocalization with BCC based on a posterior probability PP.H4 >0.92. Furthermore, MR-PheWAS analysis showed that BCC was the most significant phenotype associated with PTGES2 and RNASET2 among 2,408 phenotypes in the FinnGen R10 study. Therefore, PTGES2 and RNASET2 are highlighted as effective biomarkers and therapeutic targets for BCC within the phenome-wide human disease category. Conclusion The study identifies PTGES2 and RNASET2 plasma proteins as novel, reliable biomarkers and therapeutic targets for BCC, suggesting more effective clinical application strategies for patients.

Abstract
Cancer is a diverse disease caused by transcriptional changes involving genetic and epigenetic features that influence a huge variety of genes and proteins. Skin cancer is a potentially fatal disease that affects equally men and women globally and is characterized by many molecular changes. Despite the availability of various improved approaches for detecting and treating skin cancer, it continues to be the leading cause of death throughout society. This review highlights a general overview of skin cancer, with an emphasis on epidemiology, types, risk factors, pathological and targeted facets, biomarkers and molecular markers, immunotherapy, and clinical updates of investigational drugs associated with skin cancer. The skin cancer challenges are acknowledged throughout this study, and the potential application of novel biomarkers of skin cancer formation, progression, metastasis, and prognosis is explored. Although the mechanism of skin carcinogenesis is currently poorly understood, multiple articles have shown that genetic and molecular changes are involved. Furthermore, several skin cancer risk factors are now recognized, allowing for efficient skin cancer prevention. There have been considerable improvements in the field of targeted treatment, and future research into additional targets will expand patients' therapeutic choices. In comparison to earlier articles on the same issue, this review focused on molecular and genetic factors and examined various skin cancer-related factors in depth.

Abstract
PURPOSE To enhance the characterization of primary bulbar conjunctival basal cell carcinoma (BCC) clinically and histologically, via report of a case and review of the relevant medical literature. OBSERVATIONS We report the case of a 73-year-old man with no history of skin cancer who presented with a bulbar conjunctival nodule without connection to the eyelid or caruncle, originally thought to represent a pyogenic granuloma. After one month without improvement on topical prednisolone, excisional biopsy was performed, with routine histopathology and immunohistochemistry. The tumor was found histologically to be primary conjunctival BCC. Immunostaining exhibited negative Ber-EP4 and S100, mostly negative CK7 and EMA, and positive p63. Margins were negative, and the patient had no recurrence six months after excision. CONCLUSIONS AND IMPORTANCE Primary conjunctival BCC must be considered in the differential diagnosis of a conjunctival lesion which may initially appear benign but does not behave as expected clinically. The location of the tumor in the case presented here refutes a prior postulate that primary conjunctival BCC arises from basal adnexal epithelium in the caruncle. Of the immunohistochemical findings, only the Ber-EP4 result differed from the typical immunostaining profile of cutaneous BCC. Further study is needed to determine the frequency of Ber-EP4 positivity in primary conjunctival BCC.

Abstract
Non-melanoma skin cancers (NMSCs) are the most common human neoplasms world-wide. In detail, basal cell carcinoma (BCC) is the most frequent malignancy in the fair-skinned population. The incidence of BCC remains difficult to assess due to the poor registration practice; however, it has been increasing in the last few years. Approximately, 85% of sporadic BCCs carry mutations in Hedgehog pathway genes, especially in PTCH, SUFU and SMO genes, which lead to the aberrant activation of GLI transcriptional factors, typically silent in cells of adult individuals. The management of advanced BCC (aBCC), both metastatic (mBCC) and locally advanced BCC (laBCC), not candidates for surgical excision or radiotherapy, remains challenging. The discovery of mutations in the Hh signaling pathway has paved the way for the development of Hh pathway inhibiting agents, such as vismodegib and sonidegib, which have represented a breakthrough in the aBCC management. However, the use of these agents is limited by the frequent occurrence of adverse events or the development of drug resistance. In this review, we thoroughly describe the current knowledge regarding the available options for the pharmacological management of aBCCs and provide a forward-looking update on novel therapeutic strategies that could enrich the therapeutic armamentarium of BCC in the near future.

Abstract
The causality of ease of skin tanning and radiation-related disorders of the skin and subcutaneous tissue with basal cell carcinoma (BCC) remains unclear. Our objective was to investigate whether ease of skin tanning and radiation-related disorders of the skin and subcutaneous tissue have a relation with the occurrence and development of BCCs. In this work, independent genetic variants strongly associated (P < 5e-08) with ease of skin tanning and radiation-related disorders of the skin and subcutaneous tissue were selected as instrumental variables from corresponding genome-wide association studies (GWASs). Summary-level data for BCC was obtained from the European Bioinformatics Institute (EBI). Two-sample univariable and multivariable Mendelian randomization (MR) were performed. Sensitivity analyses were preformed via MR-Egger regression, heterogeneity test, pleiotropy test, and leave-one-out sensitivity test. We observed positive causal effect both for ease of skin tanning [odds ratio (OR) = 2.102, 95% confidence interval (CI) = 1.915-2.306, P = 2.71e-55] and radiation-related disorders of the skin and subcutaneous (OR = 1.603, 95% CI = 1.483-1.734, P = 3.41e-32) on occurrence of BCCs based on univariable MR analyses. In the multivariable mendelian randomization (MVMR) analysis of BCC risk, we also observed a direct causal effect of ease of skin tanning (ORMVMR = 1.623, 95% CI = 1.445-1.824, PMVMR =3.41e-16) and radiation-related disorders of the skin and subcutaneous (ORMVMR = 1.208, 95% CI = 1.107-1.319, PMVMR = 2.46e-05) on BCCs. The findings suggest that the high risk of BCCs can be attributed to ease of skin tanning and radiation-related disorders of the skin and subcutaneous tissue.

Abstract
Research in normal tissue radiobiology is in continuous progress to assess cellular response following ionizing radiation exposure especially linked to carcinogenesis risk. This was observed among patients with a history of radiotherapy of the scalp for ringworm who developed basal cell carcinoma (BCC). However, the involved mechanisms remain largely undefined. We performed a gene expression analysis of tumor biopsies and blood of radiation-induced BCC and sporadic patients using reverse transcription-quantitative PCR. Differences across groups were assessed by statistical analysis. Bioinformatic analyses were conducted using miRNet. We showed a significant overexpression of the FOXO3a, ATM, P65, TNF-α and PINK1 genes among radiation-induced BCCs compared to BCCs in sporadic patients. ATM expression level was correlated with FOXO3a. Based on receiver-operating characteristic curves, the differentially expressed genes could significantly discriminate between the two groups. Nevertheless, TNF-α and PINK1 blood expression showed no statistical differences between BCC groups. Bioinformatic analysis revealed that the candidate genes may represent putative targets for microRNAs in the skin. Our findings may yield clues as to the molecular mechanism involved in radiation-induced BCC, suggesting that deregulation of ATM-NF-kB signaling and PINK1 gene expression may contribute to BCC radiation carcinogenesis and that the analyzed genes could represent candidate radiation biomarkers associated with radiation-induced BCC.

Abstract
Mounting evidence indicates that the microbiota, the unique combination of micro-organisms residing in a specific environment, plays an essential role in the development of a wide range of human diseases, including skin cancer. Moreover, a persistent imbalance of microbial community, named dysbiosis, can also be associated with oxidative stress, a well-known emerging force involved in the pathogenesis of several human diseases, including cutaneous malignancies. Although their interplay has been somewhat suggested, the connection between microbiota, oxidative stress, and skin cancer is a largely unexplored field. In the present review, we discuss the current knowledge on these topics, suggesting potential therapeutic strategies.

Abstract
Non-melanoma skin cancer (NMSC) is one of the most frequent types of malignancy in the human body with an increasing incidence. Short, non-coding RNA molecules called microRNAs (miRNAs) can control post-transcriptional gene expression and they have a significant role in several physiological cellular processes and pathologies, including cancer. Depending on the functions of the genes, miRNAs may function as oncogenes or tumor suppressors. The aim of this paper was to describe the role of miRNA-34a and miRNA-221 in head and neck NMSC. Thirty-eight NMSC match paired (tumor and adjacent) tissue samples were evaluated by qRT-PCR. Total RNA was extracted and isolated from tissue samples using the phenol-chloroform (Trireagent) method according to the manufacturer's protocol. The concentration of RNA was measured by a NanoDrop-1000 spectrophotometer. The expression level of each miRNA was calculated by threshold cycle. For all statistical tests, the 0.05 significance level was used and two-tailed p values. All analyses were conducted in an R environment for statistical computing and graphics. We found the miRNA-221 being overexpressed in squamous cell carcinoma (SCC) (p < 0.05), basal cell carcinoma (BCC) and basosquamous cell carcinoma (BSC) compared with adjacent normal tissue. Additionally, the levels of miRNA-221 were two times higher (p < 0.05) in cases where the excision of the tumor was done with positive margins (R1), which means that we are the first to highlight the potential role of miRNA-221 in the microscopical local invasion. Mi-RNA-34a expression was altered in the malignant tissue compared with the adjacent normal one both in BCC and SCC but not statistically significantly. In conclusion, NMSC are challenging because of their increasing incidence and rapidly evolving development and discovering their molecular mechanisms of action lead us to understand tumorigenesis and evolution, while also contributing to the implementation of novel therapeutic keys.

Basal cell carcinomas of the scalp after radiotherapy for tinea capitis: Clinicopathological study in a case series of 96 patients with analysis of 427 tumours. Australas J Dermatol 2023; 64:100-107.

Abstract
BACKGROUND/OBJECTIVES Low-dose X-ray radiotherapy to treat tinea capitis during childhood is a well-known risk factor for scalp basal cell carcinomas (BCCs). Post-radiotherapy BCCs are often multiple, and it has been suggested that they display more aggressive features. Our main objective was to study the clinicopathological aspects of post-radiotherapy BCCs to evaluate their biological behaviour and identify features that may differ from other BCCs. METHODS We performed an observational, retrospective study assessing multiple clinical and pathological characteristics of patients with post-radiotherapy BCCs. RESULTS We studied 96 patients with 427 post-radiotherapy scalp BCCs. Post-radiotherapy BCCs were often multiple (median of 4 lesions/patient, ranging from 1 to 54). Significant comorbidities included a high incidence of thyroid disease and meningiomas. Recurrences were observed in 23% of patients, but there may be confounding factors, such as referral bias, heterogenous treatment modalities and occurrence of new tumours due to field effect. We found a high incidence of infundibulocystic BCCs (in 14.6% of patients and corresponding to 5.4% of the total number of tumours), trichoblastomas (5.2%) and neurofibromas of the scalp (10%). CONCLUSIONS This study is consistent with the occurrence of multiple lesions (sometimes numerous) and a relatively high tendency for recurrence in post-radiotherapy BCCs, as suggested by previous studies. We also found a high incidence of the infundibulocystic variant and a higher risk of follicular tumours and neurofibromas, which suggests that radiotherapy may influence the type of differentiation of BCCs and contribute to induce neoplasms of different cell lines.

Background Malignancy is known to be a major cause of death in adult congenital heart disease (ACHD). However, data regarding cardiovascular and cancer-related outcomes in ACHD are lacking. Methods We conducted a retrospective single-center cohort study comprising patients with ACHD and malignancy. The primary outcome was all-cause mortality. Key secondary outcomes included major adverse cardiovascular and cerebrovascular events (MACCE), cardiotoxicity events and consequent cancer therapy modifications. Results Sixty-eight patients with ACHD and a history of cancer were included in the study. 82% of patients had moderate or great ACHD anatomic complexity. Over a median follow-up of 5 years after cancer diagnosis, 16 (24%) patients died, with 69% of deaths being due to cancer. Univariate predictors of mortality were baseline arrhythmia (OR 3.82, 95% CI 1.15-12.67, p = 0.028), baseline diuretic therapy (OR 3.54, 95% CI 1.04-12.04, p = 0.044) and advanced cancer stage at diagnosis (OR 2.37, 95% CI 1.32-4.25, p = 0.004). MACCE occurred in 40 (59%) patients and was independently predicted by baseline diuretic requirement (OR 9.91, 95% CI 1.12-87.85, p = 0.039). A 14% incidence of cardiotoxicity was seen; 3 patients needed modification and 1 patient needed temporary interruption of cancer therapy for 2 weeks. Conclusions Considerable mortality occurred in this cohort of patients with ACHD and cancer; most deaths were cancer-related. A high rate of MACCE was observed, yet rates of obligatory modification of cancer therapy due to cardiotoxicity were low.

Abstract
Non melanoma skin cancer (NMSC) is one of the most common types of skin cancer. It has a number of subtypes, which include basal cell carcinoma, cutaneous squamous cell carcinoma and Merkel cell carcinoma. MicroRNAs are short, non-coding RNA (ribonucleic acid) molecules, capable of regulating gene expression at a post transcriptional level. They play a pivotal role in a variety of physiologic cellular functions and pathologies, including malignant diseases. The development of miRNAs represents an important study field, which has been extensively exploited in melanoma for almost a decade with promising results, therefore we consider it a stepstone for further research projects also in non-melanoma skin cancers. The aim of our study was to explore the current literature in order to present the role of the different miRNAs in some of the most frequent types of NMSC pertaining to oncogenesis, evolution and therapy. The most relevant and accurate available data from the literature were evaluated. Our study concluded that there are almost 100 miRNAs which can be upregulated or downregulated and can play a role in oncogenesis. They can be easily identified in circulation, are stable and they can be important diagnosis/prognosis and therapy monitoring markers.

Abstract
The results of a 13-year clinical observation of a patient after treatment for basal cell carcinoma of the skin of the right cheek Ist cT1N0M0 are presented. The history of the course of the disease is associated with the fact that the patient underwent radiation therapy in early childhood for hemangioma of the lower eyelid of the right eye and right cheek. In 2008, against the background of post-radiation changes in the area of the right cheek, basal cell carcinoma was diagnosed at the Moscow Oncological Research Institute. P.A. Herzen. At the Center for Laser and Photodynamic Diagnostics and Tumor Therapy, the patient underwent organ-preserving PDT treatment. A course of photodynamic therapy (PDT) with 5-aminolevulic acid was carried out. Subsequently, the patient was followed up until 2021 without relapse in the PDT area. In 2016, the patient was diagnosed with a relapse of the disease in the form of a new focus of basal cell carcinoma of the upper eyelid skin on the right Iast cT1N0M0. The patient underwent a course of PDT with a chlorin e6-based photosensitizer. Complete regression of the tumor was achieved, the period of relapse-free follow-up was 5 years.

Abstract
ABSTRACT Basal cell carcinoma (BCC) has been linked mostly to ultraviolet radiation exposure, but ionizing radiation has also been implicated in the genesis of a subset of BCCs occurring after radiotherapy. We present a 93-year-old woman with 4 BCCs of the scalp after radiotherapy for tinea capitis, diagnosed after a latency period of over 80 years. The largest lesion was located on the right temporal region and corresponded to a BCC of mixed type, with nodular, infiltrative, and micronodular components. We performed genomic study with array comparative genomic hybridization in samples from each BCC, which revealed more imbalances in the largest lesion than in the remaining ones, correlating with its higher histological complexity. Furthermore, this was the only lesion presenting loss at 2p22.3, where is mapped the BIRC6 gene associated with regulation of apoptosis, and loss at 16q24.3, where is mapped FANCA gene, responsible for DNA repair and maintenance of chromosome stability. Despite these differences, there were aberrations shared by all tumor samples, suggesting a common genetic signature. Our report describes, to the best of our knowledge, the longest latency period between exposure to radiotherapy and the diagnosis of BCC. The genomic study showed imbalances common to all tumor samples but also differences that could explain their heterogeneity in terms of histological subtype and biological potential. In addition, these differences could also be a consequence of different times in the evolution of the lesions at the moment of presentation, thus having a diverse combination of accumulated genomic imbalances.

Abstract
Introduction Basal cell carcinoma (BCC) located on the genitalia is rare; data on the clinicopathologic features and survival outcomes are only available through case reports and small case series studies. Purpose This study aimed to explore the epidemiology and identify the prognostic factors of genital BCCs. Methods We queried the 18 registries of the Surveillance, Epidemiology, and End Results database for patients with primary BCCs of the genital skin from 2000 through 2017. The primary endpoint was overall survival (OS) and disease specific survival (DSS). Kaplan-Meier survival analysis was conducted to assess the impact of clinicopathological variables on OS and DSS. Multivariate Cox proportional hazards model was performed to evaluate risk factors for OS. Results A total of 1,607 cases of genital BCCs were identified. The cohort was composed of 1,352 women (84.1%) and 255 men (15.9%). The median (P25, P75) age of the entire cohort was 73(63–82)years. White patients accounted for 87.2% of the cases. For women and men, the most common site of involvement was the labia majora (89.6%) and scrotum (74.5%), respectively. The majority of patients with genital BCC had localized disease (75.5%). Kaplan-Meier survival analysis showed that female genital BCCs experienced better DSS than men (209.1 months vs 194.8 months); for men, BCCs located on the scrotum had better DSS and OS than those on the penis (P < 0.05 for both endpoints). All patients with distant disease died of disease-specific death, and the average survival time was 8.2 months. Multivariate analysis revealed that age, primary site, and stage were independent determinants of OS for men, while tumor size, histologic subtype, and race were not. For women, factors associated with worse OS included increasing age, tumor size more than 2 cm, and distant disease; factors associated with a decreased risk included “other” and “unknown” races. Conclusion The prognosis of genital BCCs is excellent, while the survival of distant disease is very poor. Despite similar clinicopathologic features and overall survival outcomes, men and women should be treated as two different entities when making survival predictions.

Abstract
Understanding of cancer with the help of ever-expanding cutting edge technological tools and bioinformatics is revolutionizing modern cancer research by broadening the space of discovery window of various genomic and epigenomic processes. Genomics data integrated with multi-omics layering have advanced cancer research. Uncovering such layers of genetic mutations/modifications, epigenetic regulation and their role in the complex pathophysiology of cancer progression could lead to novel therapeutic interventions. Although a plethora of literature is available in public domain defining the role of various tumor driver gene mutations, understanding of epigenetic regulation of cancer is still emerging. This review focuses on epigenetic regulation association with the pathogenesis of non-melanoma skin cancer (NMSC). NMSC has higher prevalence in Caucasian populations compared to other races. Due to lack of proper reporting to cancer registries, the incidence rates for NMSC worldwide cannot be accurately estimated. However, this is the most common neoplasm in humans, and millions of new cases per year are reported in the United States alone. In organ transplant recipients, the incidence of NMSC particularly of squamous cell carcinoma (SCC) is very high and these SCCs frequently become metastatic and lethal. Understanding of solar ultraviolet (UV) light-induced damage and impaired DNA repair process leading to DNA mutations and nuclear instability provide an insight into the pathogenesis of metastatic neoplasm. This review discusses the recent advances in the field of epigenetics of NMSCs. Particularly, the role of DNA methylation, histone hyperacetylation and non-coding RNA such as long-chain noncoding (lnc) RNAs, circular RNAs and miRNA in the disease progression are summarized.

Abstract
Breast-conserving surgery with adjuvant radiation therapy has become the standard of care for women with early stage breast cancer, and as a result, a large number of patients are affected by the cutaneous sequelae of radiation therapy. These dermatologic toxicities may present during treatment or years later and can significantly impact patients’ quality of life. In this review, we discuss the clinical presentation, prevention, and management of radiation-induced cutaneous toxicities in women with breast cancer, including radiation dermatitis, radiation recall, radiation-induced morphea, radiation-induced fibrosis, and cutaneous malignancies in irradiated skin.

Abstract
An efficient and novel modeling approach is proposed in this paper for identifying proteins or genes involved in melanoma skin cancer. Two types of classifiers are modeled, based on the chemical structure and hydropathy property of amino acids. These classifiers are further implemented using NI LabVIEW-based hardware kit to observe the real-time response for proper diagnosis. The phase responses, pole-zero diagrams, and transient responses are examined to screen out the genes related to melanoma from healthy genes. The performance of the proposed classifier is measured using various performance measurement metrics in terms of accuracy, sensitivity, specificity, etc. The classifier is experimented along with a color code scheme on skin genes and illustrates the superiority in comparison with traditional methods by achieving 94% of classification accuracy with 96% of sensitivity.Graphical abstract An equivalent electrical model is developed for designing melanoma classifier. Initially, each amino acid is modeled using the RC passive circuit depending on their physicochemical structure and hydropathy nature, to form a gene structure model. The melanoma-related genes are detected by phase, transient, and color code analysis.

Abstract
OBJECTIVES Biological weapons are one of the oldest weapons of mass destruction used by man. Their use has not only determined the outcome of battles, but also influenced the fate of entire civilizations. Although the use of biological weapons agents in a terrorist attack is currently unlikely, all services responsible for the surveillance and removal of epidemiological threats must have clear guidelines and emergency response plans. METHODS In the face of the numerous threats appearing in the world, it has become necessary to put the main emphasis on modernizing, securing, and maintaining structures in the field of medicine which are prepared for unforeseen crises and situations related to the use of biological agents. RESULTS This article presents Poland's current preparation to take action in the event of a bioterrorist threat. The study presents both the military aspect and procedures for dealing with contamination. CONCLUSIONS In Poland, as in other European Union countries fighting terrorism, preparations should be made to defend against biological attacks, improve the flow of information on the European security system, strengthen research centers, train staff, create observation units and vaccination centers, as well as prepare hospitals for the hospitalization of patients-potential victims of bioterrorist attacks.

Abstract
Recent large-scale GWAS and large epidemiologic studies have accelerated the discovery of genes and environmental factors that contribute to the risk of keratinocyte carcinoma (KC), which includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). This Review summarizes the genomic regions associated with SCC and BCC risk, examines the genetic overlap between SCC and BCC, and discusses biological pathways involved in SCC and BCC development. Next, we review environmental factors that are associated with KC risk, including those that are shared between SCC and BCC as well as others that associated with only one type of KC. We conclude with a critical appraisal of current research and potential directions for future research.

Abstract
Superoxide dismutase is widespread in the human body, including skin and its appendages. Here, we focus on human skin copper/zinc superoxide dismutase, the enzyme that protects skin and its appendages against reactive oxygen species. Human skin copper/zinc superoxide dismutase resides in the cytoplasm of keratinocytes, where up to 90% of cellular reactive oxygen species is produced. Factors other than cell type, such as gender, age and diseased state influence its location in skin tissues. We review current knowledge of skin copper/zinc superoxide dismutase including recent studies in an attempt to contribute to solving the question of its remaining unexplained functions. The research described here may be applicable to pathologies associated with oxidative stress. However, recent studies on copper/zinc superoxide dismutase in yeast reveal that its predominant function may be in signaling pathways rather than in scavenging superoxide ions. If confirmed in the skin, novel approaches might be developed to unravel the enzyme's remaining mysteries.

Abstract
Telomere length per se a heritable trait has been reported to be associated with different diseases including cancers. In this study, based on arsenic-exposed 528 cases with basal cell carcinoma (BCC) of skin and 533 healthy controls, we investigated effect of telomere length, measured by real-time PCR, on the disease risk. We observed a statistically significant association between decreased telomere length and increased BCC risk [odds ratio (OR) = 5.92, 95% confidence interval (CI) = 3.92 to 9.01, P < 0.0001]. Due to confounder effect of arsenic exposure, in a two-sample Mendelian randomization (MR), telomere length associated single-nucleotide polymorphisms as instrument variables violated valid assumptions; however, one-sample MR adjusted for arsenic exposure indicated an increased risk of BCC with short telomeres. The interaction between arsenic exposure and telomere length on BCC risk was statistically significant (P = 0.02). Within each tertile based on arsenic exposure, the individuals with shorter telomeres were at an increased risk of BCC, with highest risk being in the highest exposed group (OR = 16.13, 95% CI = 6.71 to 40.00, P < 0.0001), followed by those in medium exposure group and low exposure group. The combined effect of highest arsenic exposure and shortest telomeres on BCC risk (OR = 10.56, 95% CI = 5.14 to 21.70) showed a statistically significant departure from additivity (interaction contrast ratio 6.56, P = 0.03). Our results show that in the presence of arsenic exposure, decreased telomere length predisposes individuals to increased risk of BCC, with the effect being synergistic in individuals with highest arsenic exposure and shortest telomeres.

Vismodegibfor the treatment of radiation-induced basal cell carcinoma - a case report and brief literature study. Contemp Oncol (Pozn) 2020; 23:251-253. [PMID: 31992959 PMCID: PMC6978755 DOI: 10.5114/wo.2019.91540] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Accepted: 08/29/2019] [Indexed: 11/17/2022] Open
Abstract
Vismodegib is playing an increasing role in the treatment of locally advanced or metastatic basal cell carcinoma (BCC) that is not a candidate for surgery or radiotherapy, and also in radiation-induced BCC. A 22-year-old man with a history of Hodgkin lymphoma, nodular sclerosis stage IIA, from October 1994 to February 1995 treated with 25 mg/m2 doxorubicin, 10 IU/m2 bleomycin, 6 mg/m2 vinblastine, and 375 mg/m2 dacarbazine for four cycles, followed byconformal beam radiotherapy (EBRT) on laterocervical, supraclavear, and mediastinal nodes up to a total dose of 30 Gy and following EBRT boost on mediastinal nodes up to a dose of 10 Gy. Subsequently, the patient underwent conformal EBRT on lomboaortic nodes up to total dose of 30 Gy at the University Hospital of Pisa until May 1995. There was no evidence of disease, until March 2012 when the patient developed severalBCCs, occurring in the field of prior radiation, treated with local excisions. No mutations of Hedgehog (Hh) pathway or other genes were found and nevoid basal cell carcinoma syndrome was not diagnosed. In February 2018, the patient began therapy with vismodegib at standard dose of 150 mgorally daily and was treated for 10 months, with low adverse events and with pathological complete response of disease until July 2019. This experience shows that there are, however very few, BCCs not associated with genetic disorders. Vismodegib seems to be an effective and safe therapeutic approach also for radiation-related BCCs, associated with relatively low toxicity.

Abstract
Basal cell carcinoma (BCC) is the most common skin cancer and its incidence is steadily increasing. Prior radiation therapy is one of the most important risk factors for BCC. Although the mechanism remains undefined, long-term studies have shown that people exposed to radiation have an increased risk of BCC. Despite the fact that BCC occurs most frequently in sun-exposed areas of the body, patients with a history of radiation therapy have an increased risk of BCC in areas previously exposed to radiation. Here, we report a case of adenoid BCC on the abdomen in a 67-year-old woman after radiation therapy post-hysterectomy.

Abstract
Purpose: The workshop on 'Individual Radiosensitivity and Radiosusceptibility' organized by MELODI and CONCERT on Malta in 2018, evaluated the current state of assays to identify sensitive and susceptible subgroups. The authors provide an overview on potential screening assays detecting individuals showing moderate to severe early and late radiation reactions or are at increased risk to develop cancer upon radiation exposure.Conclusion: It is necessary to separate clearly between tissue reactions and stochastic effects such as cancer when comparing the existing literature to validate various test systems. Requirements for the assays are set up. The literature is reviewed for assays that are reliable and robust. Sensitivity and specificity of the assays are regarded and scrutinized for modifying factors. Accuracy of an assay system is required to be more than 90% to balance risks of adverse reactions against risk to fail to cure the cancer. No assay/biomarker is in routine use. Assays that have shown predictive potential for radiosensitivity include SNPs, the RILA assay, and the pATM assay. A tree of risk guideline for radiologists is provided to assist medical treatment decisions. Recommendations for effective research include the setup of common retrospective and prospective cohorts/biobanks to validate current and future tests.

Abstract
The Hedgehog pathway is critical for the development of diverse organs. Misactivation of the Hedgehog pathway can cause developmental abnormalities and cancers, including medulloblastoma, the most common pediatric brain tumor, and basal cell carcinoma, the most common cancer in the United States. Here, we review how basic, translational, and clinical studies of the Hedgehog pathway have helped reveal how cells communicate, how intercellular communication controls development, how signaling goes awry to cause cancer, and how to use targeted molecular agents to treat both inherited and sporadic cancers.

Abstract
Policy Points Policymakers should invest more on researching the long-term health effects of low-ionizing radiation exposure, as we are far from reaching a consensus on a topic that is of enormous importance for public health and safety. Public policies such as those limiting the import of contaminated food from areas hit by a radioactive disaster or those regulating the resident population's access to such areas should follow a precautionary approach. Neoplasm diagnosis and medical care should be designed in order to take into account the possible role of long-term, low-dose radiation exposure. Health care policies should provide effective screening and prevention strategies with a specific focus on the regions that were hit most severely by the Chernobyl nuclear fallout. Health care expenditure should be targeted, taking into account the geographical dispersion of the fallout in order to attenuate its possible effect on neoplasm incidence. CONTEXT This study investigates the association between the radioactive 137 Cesium fallout originated by the 1986 Chernobyl nuclear accident and dispersed over Western Europe, as a result of a combination of radioactive cloud passage days and rainy days over a 10-day period, and long-term health patterns and related costs. Since the half-life of 137 Cesium is 30.17 years, part of the radioactivity in the affected regions is still present today, and it is usually still detected in the food chain, although at lower concentration levels. METHODS We match longitudinal data on neoplasm incidence over the time span 2000-2013 in a number of European regions not immediately adjacent to Chernobyl with the randomly distributed levels of cesium deposition after the nuclear disaster in order to assess whether we can detect an association with the long-term health effects on the European population through a random effects model. FINDINGS Considering 3 levels of fallout deposition-low, medium, and high-hospital discharges after treatment for neoplasms are, respectively, 0.36, 0.44, and 0.98 discharges over 100 inhabitants higher compared to regions with no fallout, with the population average being around 1.7 hospital discharges by neoplasms over 100 inhabitants. We checked the robustness of our findings to a number of tests including a placebo simulation and different model specifications. CONCLUSIONS Radioactive fallout is positively associated with a higher incidence of hospital discharges after treatment for neoplasms almost 30 years after its release, with larger effects in regions where the radioactivity was more intense. Our estimates are comparable to the findings of the largest-scale study on the long-term health effects of continuous low levels of radiation exposure among workers in the nuclear industry and suggest that more research is needed on this topic, given its enormous importance for public health and safety.

Abstract
Prostate cancer is one of the most commonly diagnosed cancers and a pressing health challenge in men worldwide. Radiation therapy (RT) is widely considered a standard therapy for advanced as well as localized prostate cancer. Although this primary therapy is associated with high cancer control rates, up to one-third of patients undergoing radiation therapy becomes radio-resistant and/or has tumor-relapse/recurrence. Therefore, focus on new molecular targets and pathways is essential to develop novel radio-sensitizing agents for the effective and safe treatment of prostate cancer. Here, we describe functional studies that were performed to investigate the role of structural maintenance of chromosome-1 (SMC1A) in radioresistance of metastatic prostate cancer cells. Short hairpin RNA (shRNA) was used to suppress SMC1A in metastatic castration-resistant prostate cancer cells, DU145 and PC3. Clonogenic survival assays, Western blot, RT-PCR, and γ-H2AX staining were used to assess the effect of SMC1A knockdown on radiation sensitivity of these prostate cancer cells. We demonstrate that SMC1A is overexpressed in human prostate tumors compared to the normal adjacent tissue. SMC1A knockdown limits the clonogenic potential, epithelial-mesenchymal transition (EMT), and cancer stem-like cell (CSC) properties of DU145 and PC3 cells and enhanced efficacy of RT in these cells. Targeted inhibition of SMC1A not only plays a critical role in overcoming radio-resistance in prostate cancer cells, but also suppresses self-renewal and the tumor-propagating potential of x-irradiated cancer cells. We propose that SMC1A could be a potential molecular target for the development of novel radio-sensitizing therapeutic agents for management of radio-resistant metastatic prostate cancer.

Abstract
RATIONALE Radiotherapy (RT) is widely used for both malignant and benign tumors in order to reduce the risk of recurrence, to promote tumor control, and to improve survival. However, there have been studies reported that RT is also a risk factor of secondary cancer. Very few cases of secondary malignancy after RT to high grade brain cancer have been reported due to short survival of this disease, and most RT-induced malignancies presented with sarcomatous histology. Here we present a patient with basal cell carcinoma (BCC) 14 years after RT to his brain. PATIENT CONCERNS A 28-year-old man without any underlying disease had suffered from left side weakness and clonic-tonic seizures for 12 days. DIAGNOSES His brain images showed a tumor in the right frontal lobe. The pathologic report confirmed anaplastic astrocytoma (WHO Grade III). INTERVENTIONS After craniotomy and tumor biopsy, RT was delivered. Fourteen years later, a gray-colored skin papule was noted in the previously irradiated area. The scalp biopsy revealed BCC. The scalp BCC was adequately resected. He then suffered from brain tumor recurrence and received further craniotomy for three times combined with chemotherapy with temozolomide. OUTCOMES After treatment, follow-up brain images showed that the disease was under control. There was no neurological sequela. For scalp BCC, no skin tumor recurrence has been noted to date after the resection 14 years after initial RT. He has survived for more than 26 years since his initial diagnosis of anaplastic astrocytoma, and more than 12 years from the diagnosis of scalp BCC. LESSONS Notwithstanding the risk of radiation-induced skin cancer, RT contributed to this patient's survival. The possible late adverse events should be informed to the patients.

Abstract
The relationship between the ophthalmologist and ophthalmic pathologist is particularly important in orbital disease, as diagnosis is heavily dependent on correlation with clinical context. If the patient has previously had treatment to the orbit or an adjacent area, whether for the same or a different condition, tissue changes may occur which affect the histological appearance of any specimen taken. This article is an overview of therapeutic interventions which may cause either orbital pathology or an altered appearance of the tissue, either of which can pose a diagnostic challenge. The problem of artefact is also addressed as another factor which may alter the appearance of a specimen. It is hoped that the information provided in this brief review will help clinicians better evaluate what information may be relevant when submitting a specimen.

Abstract
Basal cell carcinoma (BCC) is a slow-growing and locally aggressive skin cancer. Despite its high incidence, good quality epidemiological data are sparse. We therefore organised a retrospective study of two separate years' incidence of BCC in one county within the United Kingdom (Dorset) with an interval of 10 years between them. There were 2455 patients in 2006, and 3797 in 2016, who had a new diagnosis with corresponding crude incidences of 459.99 and 491.92/100,000 person-years. The male:female ratio was 1:071 for both years. The head and neck was the most common site, with the cheek, nose, and forehead being the most common subsites. This is a substantial increase in the incidence of BCC, and is much higher than previous reported rates for the UK. More stringent local and national registries are required to monitor the increasing numbers of BCC and help health care systems to plan preventive strategies and provide the most effective treatment.

Abstract
Thirty years after the Chernobyl nuclear power plant accident we report on a patient who was a clean-up worker, who subsequently developed multiple cutaneous basal cell carcinomas (BCCs). We used several methods to assess the biological long-term effects related to low-dose external and internal radiation exposure. Specifically, because BCC risk may be increased with ionizing radiation exposure, we endeavored to determine whether the multifocal BCCs were related to the patient's past clean-up work. We assessed cytogenetic changes using peripheral blood, and internal incorporation was measured with a whole-body counter. Gene expression alterations were determined and array-based comparative genomic hybridization was performed for copy number aberration analysis of available BCC samples. In 1,053 metaphase cells, the dicentric yield of 0.005 dicentrics, with acentrics/cell, was significantly increased compared to the established calibration curve (P < 0.001). A 2.5-fold increase in total translocations was observed compared to the expected translocation rate. No internal contamination was detected with the whole-body counter. At the RNA level, two of seven genes (HNRNPA1, AGAP4/6/8) indicated internal plutonium exposure associated with the lowest dose category found in Mayak workers (>0-0.055 Gy). Relevant DNA copy number changes were only detected within the most aggressive BCC focus. Our results suggest that the examined worker had low and more recent radiation exposure with presumably internalized radionuclides that were below the detection level of a whole-body counter. The multifocal BCC could not be related to past occupational radiation exposure. The findings from our study suggest that integrating different methodologies potentially provides an improved overall assessment of individual health risks associated with or excluding occupational radiation exposure.

Abstract
PURPOSE Basal cell carcinoma (BCC) is the most prevalent cancer worldwide. Different mechanisms are proposed to be involved in its pathogenesis such as oxidative stress. Oxidative stress, which is the consequence of the disruption of redox balance in favor of oxidants, is involved in the initiation or progression of many tumors. Thioredoxin reductase (TrxR) is a key enzyme of the thioredoxin (Trx) system, containing Trx and TrxR and NADPH, which is one of the main cellular oxidoreductases with an essential role in cellular health and survival through providing and maintaining redox balance. Therefore, we aimed to study and compare the activity and tissue distribution of TrxR in tumoral tissue and its healthy margin in patients with BCC. METHODS After biopsy and taking samples from 18 patients, TrxR activity was measured using a commercial kit and its tissue distribution was assessed immunohistochemically. RESULTS Both the activity and tissue distribution of TrxR in tumoral tissues were significantly higher compared to their healthy margins. Regarding the tissue distribution, this significant increase in TrxR in tumoral tissues was documented based on both staining intensity and abundance of positive cells in immunohistochemistry. CONCLUSIONS Based on these results, it is concluded that TrxR is involved in the pathogenesis of BCC; however, more investigations are required to clarify whether this increase is a consequence of BCC or it is an initiating mechanism.
