Background: Unlike other types of cancers, skin cancer has received little attention in Malaysia, and there's little awareness of it among the public. According to the third report of the National Cancer Registry, Malaysia (2003-2005), skin cancer ranked the tenth most common cancer in Malaysia. Aim: The objective of this study was to determine the demography and the types of skin cancers seen in the Department of Dermatology, Hospital Kuala Lumpur. Methods: This was a 13-year retrospective review of all patients with skin cancers seen at the Department of Dermatology, Kuala Lumpur Hospital between 2005-2017. All patients confirmed to have skin cancer histologically were included in this study. Results: The total number of patients diagnosed to have skin cancer between the 13-year period was 426. The mean age of the patients was 59.5 ± 17.8. 56.1% of the patients were male and 43.9% were female. Majority of the patients were Chinese (46.2%), followed by Malay (34.3%), Indian (11.5%) and other ethnic groups (8.0%). The commonest type of skin cancer was basal cell carcinoma (31.9%), followed by cutaneous lymphoma (25.4%) and squamous cell carcinoma (24.2%). Malignant melanoma was not common and accounted for 5.6% of the patients. Other types of skin cancers such as cutaneous metastasis were seen in 4.5% of patients, extramammary Paget's disease in 4.2%, Kaposi sarcoma in 1.9% and other types of tumors accounted for 2.3% of the patients. Majority of the patients with primary cutaneous lymphomas were cutaneous T-cell lymphoma (CTCL), which accounted for 97.2% of all cases of primary cutaneous lymphomas. Conclusion: Basal cell carcinoma was the commonest skin cancer seen at the Department of Dermatology between 2005-2017. This is consistent with the reports from other parts of the world, which reported basal cell carcinoma as the commonest type of skin cancer.

Abstract Introduction. Basal cell carcinoma is the most common malignant skin cancer. It is one of the so-called nonmelanoma skin cancers, the incidence of which has increased rapidly worldwide in recent years. Unfortunately, the National Cancer Registry in Poland does not classify basal cell skin cancer separately. Therefore, the precise data on the incidence in the population remain unknown. Work objective. Retrospective analysis of the incidence of basal cell carcinoma in NZOZ Med-Laser in Lublin in the years 2005 – 2015 depending on gender, age group, place of residence (urban-rural) and clinical form of the disease. Material and methodology. The data of NZOZ Med-Laser from the years 2005 - 2015 were used in the study. The data concern all patients with histopathologically diagnosed basal cell carcinoma, who during the period covered by the study were consulted either as outpatients or hospitalised in an institution providing dermatological services under contract with the National Health Fund (NFZ). Patients were divided into several groups depending on gender, age and place of residence. All groups were compared quantitatively and the results are shown in the figures below. Results. The data collected indicate that between 2005 and 2015 a total of 922 patients with basal cell carcinoma received dermatological treatment. Over the years, there has been a clear increase in the number of patients with basal cell carcinoma. The disease occurred mainly in people over 59 years of age, with the majority of women living in cities. The most common locations of the cancer are nose, cheeks, forehead and temporal area. Histopathologically, solidum, superficiale, exulceratum and pseudoadenoides were the most frequently diagnosed forms. Conclusions. Basal cell carcinoma of the skin is frequent in our society. Its incidence has been increasing in recent years. Therefore, action should be taken to create consistent international registries to gather reliable epidemiological data that would show the scale of the problem, which we are dealing with almost all over the world.

Background: The skin is a heterogeneous organ, capable of producing various types of skin tumors. The incidence of skin cancers, including melanoma and non-melanoma has been reported to have risen in many parts of the world. In Asian and African countries, individuals with pigmented races have a much lower incidence of skin cancers despite sunny hot weather. This study is aimed to analyze age, sex and site wise of distribution of skin cancers. Materials and Methods: The study included a total of 60 patients with histopathologically proven skin cancers from January 2015 to December 2018 in the department of pathology, DI skin health and referral centre, Kathmandu, Nepal. Results: A total of 60 cases of histopathologically proven skin cancer constituted 3.69% of total skin biopsies. Patient age ranged from 15 to 88 years with mean age being 61 years. The majority of the patients were in the age group of 61-70 yrs. The male to female ratio is 1:1.3. Basal cell carcinoma was the most common skin cancer constituting 43.4%, followed by squamous cell carcinoma (28.3%). The most common site of skin cancer is head & neck (73.3%), followed by lower extremities (8.3%). Other skin cancers were Bowen’s disease, melanoma, verrucous carcinoma, keratoacanthoma, trichilemmal carcinoma, extramammary Paget’s disease, Non-Hodgkin lymphoma and metastatic tumor. Conclusions: The most common type of skin cancer is basal cell carcinoma, followed by squamous cell carcinoma and head & neck being the commonest site.

Ubiquitin and ubiquitin-related proteins posttranslationally modify substrates, and thereby alter the functions of their targets. The ubiquitination process is involved in various physiological responses, and dysregulation of components of the ubiquitin system has been linked to many diseases including skin cancer. The ubiquitin pathways activated among skin cancers are highly diverse and may reflect the various characteristics of the cancer type. Basal cell carcinoma and squamous cell carcinoma, the most common types of human skin cancer, are instances where the involvement of the deubiquitination enzyme CYLD has been recently highlighted. In basal cell carcinoma, the tumor suppressor protein CYLD is repressed at the transcriptional levels through hedgehog signaling pathway. Downregulation of CYLD in basal cell carcinoma was also shown to interfere with TrkC expression and signaling, thereby promoting cancer progression. By contrast, the level of CYLD is unchanged in squamous cell carcinoma, instead, catalytic inactivation of CYLD in the skin has been linked to the development of squamous cell carcinoma. This paper will focus on the current knowledge that links CYLD to nonmelanoma skin cancers and will explore recent insights regarding CYLD regulation of NF-κB and hedgehog signaling during the development and progression of these types of human tumors.

Background: Development of nonmelanoma skin cancers (NMSCs) has been associated with certain risk factors, but studies of the association between ABO blood group and NMSCs have been rare and inconclusive. The aim of this study was to assess the association of the previously known risk factors and blood group as a new potential risk factor in NMSCs. Methods: The study included 401 patients, 202 men, and 199 women, which included 367 diagnosed cases of basal cell carcinoma and 148 diagnosed cases of squamous cell carcinoma. The control group consisted of 438 subjects, 198 men, and 240 women. A standardized questionnaire adapted for this targeted study was used. The relation between the dependent variable (NMSCs) and independent variables was investigated by logistic regression. Results: Compared to the non AB blood group, the risk of developing NMSCs was significantly higher in the AB blood group (MOR = 2.28; 95% CI = 1.41–3.69). We established a logistic model that could best describe the probability of NMSCs development. Conclusion: Study results are expected to instigate basic research into the role of A and B antigens in normal skin epithelium, NMSCs etiopathogenesis, possible effect on metastatic potential and disease prognosis, potential tumor immunotherapy, and targeted detection and prevention in subjects at an increased risk of NMSCs development.

Background: The purpose of this study was to formulate, characterize and in-vitro cytotoxicity of 5-Fluorouracil loaded controlled release nanoparticles for the treatment of skin cancer. The patents on nanoparticles (US8414926B1), (US61654404A), (WO2007150075A3) etc. helped in the selection polymers and method for the preparation of nanoparticles. Methods: In the present study nanoparticles were prepared by simple ionic gelation method using various concentrations of chitosan and sodium tripolyphosphate (TPP). Several process and formulation parameters were screened and optimized using 25-2 fractional factorial design. The prepared nanoparticles were evaluated for particle size, shape, charge, entrapment efficiency, crosslinking mechanism and drug release study. Results: The optimized 5-Fluorouracil loaded nanoparticle were found with particle size of of 320±2.1 nm, entrapment efficiency of 85.12%± 1.1% and Zeta potential of 29mv±1mv. Scanning electron microscopy and dynamic light scattering technique revealed spherical particles with uniform size. The invitro release profile showed controlled release up to 24 hr. Further study was carried using A375 basal cell carcinoma cell-line to elucidate the mechanism of its cytotoxicity by MTT assay. Conclusion: These results demonstrate that the possibility of delivering 5-Fluorouracil to skin with enhanced encapsulation efficiency indicating effectiveness of the formulation for treatment of basal cell carcinoma type of skin cancer.

Background: The purpose of this study was to formulate, characterize and conduct in vitro cytotoxicity of 5-fluorouracil loaded polymeric electrospun nanofibers for the treatment of skin cancer. The patents on electrospun nanofibers (US9393216B2), (US14146252), (WO2015003155A1) etc. helped in the selection of polymers and method for the preparation of nanofibers. Methods: In the present study, the fabrication of nanofibers was done using a blend of chitosan with polyvinyl alcohol and processed using the electrospinning technique. 5-fluorouracil with known chemotherapeutic potential in the treatment of skin cancer was used as a drug carrier. 24-1 fractional factorial screening design was employed to study the effect of independent variables like the concentration of the polymeric solution, applied voltage (kV), distance (cm), flow rate (ml / hr) on dependent variables like % entrapment efficiency and fiber diameter. Results: Scanning electron microscopy was used to characterize fiber diameter and morphology. Results showed that the fiber diameter of all batches was found in the range of 100-200 nm. The optimized batch results showed the fiber diameter of 162.7 nm with uniform fibers. The tensile strength obtained was 190±37 Mpa. Further in vitro and ex vivo drug release profile suggested a controlled release mechanism for an extended period of 24 hr. The 5-fluorouracil loaded electrospun nanofibers were found to decrease cell viability up to ≥50% over 24 hr, with the number of cells dropping by ~ 10% over 48 hr. As the cell viability was affected by the release of 5-fluorouracil, we believe that electrospun nanofibers are a promising drug delivery system for the treatment of Basal Cell Carcinoma (BCC) skin cancer. Conclusion: These results demonstrate the possibility of delivering 5-Fluorouracil loaded electrospun nanofiber to skin with enhanced encapsulation efficiency indicating the effectiveness of the formulation for the treatment of basal cell carcinoma type of skin cancer.

BACKGROUND Public awareness for BCC is particularly important, as its major risk factors — increased sun exposure and number of sunburns — are largely preventable. OBJECTIVE Determine whether social media posts from celebrities has an affect on public awareness of basal cell carcinoma. METHODS We used Google Trends to investigate whether public awareness for basal cell carcinoma (BCC) increased following social media posts from Hugh Jackman. To forecast the expected search interest for BCC, melanoma and sunscreen in the event that each celebrity had not posted on social media, we used the autoregressive integrated moving average (ARIMA) algorithm. RESULTS We found that social media posts from Hugh Jackman, a well-known actor, increased relative search interest above the expected search interest calculated using an ARIMA forecasting model. CONCLUSIONS Our results also suggest that increasing awareness by Skin Cancer Awareness Month may be less effective for BCC, but a celebrity spokesperson has the potential to increase awareness. BCC is largely preventable, so increasing awareness could lead to a decrease in incidence.

SUMMARY Basosquamous carcinoma (BSC), as described in 1910, is a distinctive variety of skin cancer and its etiology and pathological characteristics have generated much controversy over the years. Currently, BSC is considered a basal cell carcinoma (BCC) subtype with aggressive behavior and greater tendency for recurrence and metastases. We present a clinical case recently reported in our unit.
