Abstract
PURPOSE Skin cancers are among the commonest cancers worldwide, and the incidence of melanoma and non-melanoma skin cancer (NMSC) continues to rise worldwide. However, there are no comprehensive reports on skin cancer incidence in Jordan during the past two decades. This report investigates the incidence of skin cancers in Jordan, in particular their time trends for the period 2000-2016. MATERIALS AND METHODS Data on malignant melanomas (MMs), squamous cells carcinomas (SCCs), and basal cell carcinomas (BCCs) were extracted from the Jordan Cancer Registry for the period between 2000 and 2016. Age-specific and overall age-standardized incidence rates (ASIRs) were computed. RESULTS Two thousand seventy patients were diagnosed with at least one BCC, 1,364 with SCC, and 258 with MM. ASIRs were 28, 19, and 4 per 100,000 person-years for BCC, SCC, and MM, respectively. The BCC:SCC incidence ratio was 1.47:1. The risk of men developing SCCs was significantly higher than women (relative risks [RRs], 1.311; 95% CI, 1.197 to 1.436), but significantly lower for BCCs (RR, 0.929; 95% CI, 0.877 to 0.984) or melanomas (RR, 0.465; 95% CI, 0.366 to 0.591). Persons older than 60 years were at a significantly higher risk of developing SCCs (RR, 1.225; 95% CI, 1.119 to 1.340) or melanomas (RR, 2.445; 95% CI, 1.925 to 3.104), but at a significantly lower risk of developing BCCs (RR, 0.885; 95% CI, 0.832 to 0.941). The overall incidence rates of SCCs, BCCs, and melanomas increased over the 16-year study period, but this was not statistically significant. CONCLUSION To our knowledge, this is the largest epidemiologic study regarding skin cancers in Jordan and in the Arab world. Despite low incidence rates in this study, rates are higher than reported regional figures. This is likely due to standardized, centralized, and mandatory reporting of skin cancers, including NMSC.

Abstract
Type 2 diabetes mellitus (T2DM) is a leading cause of death. The prevalence of T2DM in countries of the Middle East and North Africa (MENA) region, including Jordan, is among the highest worldwide. The reason(s) behind the epidemic nature of T2DM in Jordan are unknown but warrant further exploration. Studies have indicated that T2DM could be influenced by diet and/or genetic background. Evidence suggests that numerous patients with T2DM are deficient in vitamin D. The activity of vitamin D on its target tissues may be influenced by single nucleotide polymorphisms (SNPs) in the vitamin D receptor (VDR) gene. It was therefore hypothesized that SNPs in VDR could modify the risk of T2DM. To test this hypothesis, 125 patients with T2DM were recruited along with 125 controls. The study subjects were genotyped for variations in rs2228570, rs1544410, rs7975232, and rs731236 SNPs in the VDR. The levels of 25-hydroxyvitamin D [25(OH)D] were measured from the serum. The analysis revealed that reduced 25(OH)D and age were associated with the risk of T2DM (P<0.05). Moreover, under a dominant inheritance model, the GG genotype of rs2228570 was revealed to increase the risk of T2DM in univariate and multivariate analysis (P<0.05). Additionally, a chromosomal block containing the GAAG haplotype of VDR SNPs increased the risk of T2DM (OR=1.909; CI: 1.260-2.891; P=0.0021). Collectively, the present study revealed that low levels of serum 25(OH)D and rs2228570 of the VDR gene are associated with the risk of T2DM.

Abstract
Introduction Basal cell carcinoma (BCC) is the most common cancer in humans, but the reporting of patients with BCC is still not complete. There are a limited number of analyses in the literature on BCC epidemiology. Aim To study the epidemiological as well as clinical aspects of BCC by analysing a single centre’s experience in the Lower Silesia region of Poland. Material and methods We investigated 180 patients with BCC treated in the Unit of Dermatosurgery, Department of Dermatology, Venereology, and Allergology of Wroclaw Medical University between September 2017 and December 2019. Results The mean age of patients with BCC was 70.5 ±11.9 years. The most frequently diagnosed type of BCC was nodular type, at 72% of all patients. BCC occurred most commonly on the face and neck area, at 132 (73.3%), without a statistical difference between males and females. The vast majority of cancers were located on the nose. There was a personal history of skin cancer in 29% of our patients. In 127 (70.6%) subjects, the diameter of the BCC on the day of excision was less than 2 cm. Conclusions The clinical characteristics of our cohort of BCC patients has some similarities with that reported from central Poland and other European countries. However, we found an increase in the incidence of BCC among females.

Comparison of Demographic and Clinicopathological Characteristics of Basal Cell Carcinoma on the Nose and Other Sites of the Face: A Cross-Sectional Study. IRANIAN JOURNAL OF OTORHINOLARYNGOLOGY 2021; 33:257-262. [PMID: 34692572 PMCID: PMC8507944 DOI: 10.22038/ijorl.2021.47720.2575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Accepted: 07/03/2021] [Indexed: 11/29/2022]
Abstract
Introduction: The clinicopathological characteristics of basal cell carcinoma (BCC) in different areas of the face, including the nose, are important and may be different. Accurate recognition of these characteristics may be necessary for the planning and selection of appropriate treatment. Materials and Methods: This cross-sectional study was conducted on 328 patients (131 females and 197 males) with 371 documented facial BCC in the West of Iran within 2013-2018. The demographic and clinicopathological data of the patients in the nose area were compared with other sites of the face by appropriate statistical methods. Results: Out of 371 lesions, 38.8% of the cases were on the nose, 75.8% were primary lesions, 97.8% had no perineural invasion, 89.2% were nodular, and 65.8% were of nodular clinical and pathologic type, which were the most common variables of patients. It was revealed that early-onset (P<0.001), smaller size (P<0.001), high-risk pathologic type (P=0.01), and recurrent lesions (P=0.013) were significantly higher in the nasal BCC. However, there was no significant difference between BCC in the nose and other sites of the face in terms of gender (P=0.654), high-risk clinical type (P=0.06), and perineural invasion (P=0.275). Conclusion: Considering the nasal site as an important cosmetic unit, more limitation of the nose in performing any procedure, and presence of the more risk factors in the nose than in other areas of the face, the definite treatment of nasal BCC requires special attention, expertise, and experience.

Abstract
Objectives: The paper presents the reconstructive options of the lower eyelid region in patients who have benefited from the excision of basal cell carcinomas. Methods: The study was based on the clinical and evolutionary particularities analyzed in a series of cases, the patients benefiting from excision and reconstruction for the treatment of basal cell carcinomas located at the level of the orbital region. Results: Following the surgical treatment, the local evolution was favorable with a good functional recovery. The aesthetic results were strongly influenced by the stage of the neoplasm, the final aspect being satisfactory for the patients included in the study. Conclusion: Early diagnosis and rapid and effective surgical treatment are associated with favorable results from a functional and aesthetic point of view. Delayed surgery and treatment of relapses are associated with increased risks and inferior results.

Abstract
Objective Our aim in this study is to define the histopathological subtypes, body site distribution, and incidence rates of single or multiple of BCCs. The study is conducted on patients from a single institution in Istanbul which has a migrant-receiving population reflecting that of the country overall. Method We retrospectively analyzed data concerning 896 cases of BCC seen between 2014 and 2018. Data about patient demographics (age and sex), tumor diameter,its anatomic localization, histological type, presence of ulceration, lymphovascular/perineural invasion, and single or multiple tumor formations were retrieved from both the hospital’s automated system and archived records of the pathology clinic. Results Our univariate analysis showed that the patients’ age, tumor size, and tumor multicentricity were all significantly related to their gender (p=0.011, p=0.001, and p=0.021, respectively). Further, age, male gender, and tumor size were all significantly related to tumor multicentricity (p=0.003, p=0.021, and p=0.001, respectively). BCC was most commonly found in male, and the diameters of the BCC tumors were also larger in male patients. Multiple BCC was more frequently seen in older and male patients, and the tumors had larger diameters in these groups. The nodular type of BCC was the most frequently seen type in all age groups. Conclusion As our study is the first BCC study that has the greatest number of cases in Turkey and as Istanbul reflects the population of Turkey, it is important for the data of BCC cases in Turkey.

Histopathologic patterns of cutaneous malignancies in individuals with oculocutaneous albinism in Anambra state, Nigeria: a paradigm swing? Ecancermedicalscience 2020; 14:1013. [PMID: 32256696 PMCID: PMC7105334 DOI: 10.3332/ecancer.2020.1013] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Indexed: 11/06/2022] Open
Abstract
Background A high proportion of skin cancers in Nigeria occur in Individuals with oculocutaneous albinism (OCA). A reduction or absence of melanin, a skin pigment with photoprotective properties, makes them susceptible to skin malignancies such as squamous cell carcinomas (SCCs), basal cell carcinomas (BCCs) and rarely melanomas. Globally, BCCs are the commonest cutaneous malignancies among Caucasians and in fair-skinned Africans. This has been attributed to the greater effect of melanin in protecting against UV damage in the basal layer of the epidermis. Older retrospective studies on African albinos suggested that SCCs accounted for a higher prevalence of skin cancers in albinos, followed by BCCs. Melanoma has been consistently documented to be rare in all of these reports. Recent reports however noted BCCs to occur at an increasing frequency, suggesting a higher frequency than previously documented. These conflicting reports reflect the need to re-explore the pattern of cutaneous malignancies in albinos in order to reconcile the role of pigmentation, UV exposure and the variance between the frequencies of the different keratinocyte skin cancers among extreme skin phenotypes. This study explores the pattern of cutaneous malignancies seen in albinos in South East Nigeria. Objective To determine the pattern of cutaneous malignancies among albinos in Anambra state, Nigeria. Materials and methods A cross-sectional study conducted in Anambra State, Nigeria. Ninety albinos from the Albino foundation Anambra state were recruited. Malignant dermatoses were characterized clinically and confirmed by histology. Fifty-eight lesions from 30 albinos were biopsied to determine the presence of malignancy. Results Skin cancers were seen in 20.98% of all participants and in 18 (60%) of all the albinos who had skin biopsy. The SCC/BCC ratio was 1.0: 2.3. There was no cutaneous melanoma. Conclusion Contrary to previous reports, it would appear that the pattern of cutaneous malignancies in albinos shows the same trend as that seen in Caucasians and fair-skinned Africans.

Abstract
We aimed to elucidate the role of intraoperative clean surgical margin (iCSM) determined according to lesion size and duration to obtain appropriate histological clean surgical margin (hCSM) in high-risk basal cell carcinoma (BCC) patients evaluated according to National Comprehensive Cancer Network (NCCN) criteria considering the tumor size and/or location. The contribution of lesion area to determine iCSM was also evaluated. Patients with high-risk BCC requiring surgical management were included. iCSM, hCSM, and clinical variables including sec, age, longest edge, location and area, and follow-up duration were recorded. In total, 96 lesions were evaluated. Lesions were mostly located in the mask area and other face region (93.8%). Lesions located on the nose comprised 50%, 34.1%, and 26.3% in the BCC-5, BCC-7, and BCC-10 lesions, respectively. The hCSMs were positive in 11.5%, 9.1%, and 3.8% of the BCC-5, BCC-7, and BCC-10 lesions, respectively. The deep surgical margin was positive in 15.4%, 4.5%, and 7.7% of the BCC-5, BCC-7, and BCC-10 lesions, respectively. The calculated risk for the positive surgical margin if the BCC-10 lesions were done like the BCC-7 was 15.4%. No recurrence was during follow-up duration. As supported by the findings of the present study, to obtain an adequate hCSM in the high-risk BCC lesions, the iCSM determined according to NCCN recommendations may not be optimal. Nevertheless, after their categorization according to lesion size and disease duration for excision with 5-, 7-, and 10-mm iCSMs, it is possible to obtain a small but important improvement in the outcome of patients.

Abstract
INTRODUCTION Basal cell carcinoma (BCC) is a non-melanocytic skin malignancy arising from basal cells of epidermis or follicular structures. Etiology of BCC is a multifactorial combination of genotype, phenotype, and environmental factors. There are several clinical variants of BCC including nodular, cystic, superficial, morphoeic, keratotic, pigmented and micronodular. AIM The aim of our study was to analyze the recent clinical trends of basal cell carcinoma by reviewing a single institution's experience. METHODS Total number of 422 patients clinically diagnosed with basal cell carcinoma were included in the study. Data on age, gender, skin type, personal and family history, duration of disease, localization of lesions, clinical type of lesions, and recurrence rate were collected and analyzed. The data were statistically evaluated. RESULTS More than 80% of all BCC's were located on sun-exposed skin areas (p<0.05).The male /female ratio was 1:0.92. The nodular BCC was the most frequent type (59.2%), followed by the superficial (16.1%), pigmented (15.2%) and morphoeic (9.5%) types. The nodular and pigmented types were predominant located on the head and neck, whereas the trunk was the most common location for the superficial type (p<0.05). The tumor is commonly found in concomitance with skin lesion related to chronic sun exposure, such as actinic keratoses, solar lentigines and facial telangiectasia. During this study period, 41 cases showed recurrence of the cancer as the overall recurrence rate was 9.7%. There were no cases with metastasis or fatal outcome. CONCLUSIONS The factors related to the development of BCC were older age and exposure to ultraviolet rays both in recreational and in occupational form. The prevention of BCC is based on the knowledge of risk factors, early diagnosis and treatment, particularly in susceptible populations.

Abstract
Objective: Basal cell carcinoma (BCC) is the most common malignancy in humans and represents a growing public health care problem. The major etiological factors contributing to BCC development are exposure to ultraviolet radiation and genetic alterations. BCC is primarily caused by dysregulation of sonic Hedgehog (HH) signaling pathway in basal cells of the skin. BCC can be classified into low risk non-aggressive and high risk aggressive subtypes. BCC subtypes differentiation is essential for prognosis and for better disease management and treatment strategies. The aim of this study was to assess the correlation between PTCH1 protein expression level and the aggressiveness of BCC histopathology. Methods: Archival paraffin embedded blocks containing BCC were retrieved from a cohort of 101 patients. Immunohistochemistry staining was performed to assess the expression level of PTCH1 which is a key component of Hedgehog pathway. Results: 101 paraffin embedded samples were evaluated and classified as high risk and low risk BCC subtypes by histopathological finding. High risk BCC subtypes were found in 40 samples (39.6%) and low risk subtypes were identified in 61 samples (60.4%). Nodular was the most frequent subtype which was found in (56/ 101), followed by infiltrative (22/101) and micronodular (14/ 101) subtypes. Positive PTCH1 expression was found highest in nodular subtypes (46.5%). Conclusion: In this study, the correlation between low risk or high risk BCC subtypes and PTCH1 expression level was not statistically significant (p>0.05), but the frequency of positive PTCH1 expression was found to be higher in low risk subtypes than high risk BCC subtypes.

Abstract
Renal cell carcinoma (RCC) is a common urinary system cancer with high morbidity and mortality rate. Clear cell renal cell carcinoma (ccRCC) is a highly aggressive and common type of RCC. More and effective therapeutic targets are badly needed for the treatment of ccRCC. Kinesin family protein (KIF)20B, also named M-phase phosphoprotein 1, was reported as a microtubule-associated, plus-end-directed kinesin. KIF20B was involved in multiple cellular processes such as cytokinesis. Multiple studies indicated the oncogenic role for KIF20B in several types of tumors, including breast cancer and bladder cancer. However, the possible role of KIF20B in the progression of renal carcinoma is still unknown. Herein, our study demonstrated that KIF20B was relatively highly expressed in ccRCC tissues. In addition, KIF20B was inversely related to the clinical features including tumor size and T stage. We further found that inhibition of the KIF20B expression by a specific short hairpin RNA obviously reduces proliferation of ccRCC cells both in vitro and in vivo. Our study reveals the involvement of KIF20B in ccRCC progression. Generally, KIF20B is a promising novel therapeutic for the treatment of clear cell RCC.
