PURPOSE: To describe the epidemiological profile of basal cell carcinoma patients at a private hospital in São Paulo and to evaluate the treatment adopted. METHODS: A prospective study of 202 patients, on which 253 lesions were diagnosed for histopathological exam as basal cell carcinoma within the period of January 2001 to September 2003, in the Plastic Surgery Residency Program at the Hospital Jaraguá. The susceptibility factor of the host, the environment variables, the characteristics of the lesions and the efficacy of the treatment were examined. The data were statistically evaluated. RESULTS: The incidence of basal cell carcinoma was 126 cases per 100,000 patients in a period of 32 months (36 cases per 100,000 patients/year). The patients were evenly distributed in terms of sex: 48% male and 52% female. The greater incidence was in patients between the ages of 60 and 80 years and the average was 64 years. The survey revealed susceptibility factors such as white race and phototypes I and II in 95.5% of the patients. Exposition to ultraviolet radiation was reported by 77% of the patients and the most frequent location of tumors was on the face (71.2% of the cases). Actinic keratosis and a history of skin cancer were reported in 43.6% and in 25% of the cases, respectively. The adopted treatment was surgery in 99.4% of the cases and only one patient was treated with radiotherapy. Twenty lesions (8%) had incomplete excision.The recurrence rate was 2% (5 cases). There were no cases with metastasis or fatal outcome. CONCLUSIONS: The factors related to the development of basal cell cancer which were significantly present in the population surveyed were: older age, white individuals, phototypes I and II, presence of actinic keratosis, previous history of non-melanoma skin cancer and exposure to ultra-violet rays both in recreational and in occupational form.The surgical treatment employed was effective with a rate of incomplete excision and recurrence similar to those found in the literature.

Although malignant melanoma (MM) and both basal cell carcinoma (BCC) and actinic keratosis (AK) are sun-induced lesions, the coexistence of these entities at the same anatomical site (collision tumour) is exceedingly rare. We report the case of a 54-year-old woman with a known history of xeroderma pigmentosum variant (XPV) who presented with 2 separate skin lesions over the middle and upper right forearm, respectively. The clinical impression was that of BCCs or squamous cell lesions. On histological examination, both specimens showed features of melanoma <em>in situ </em>(MIS). In the first lesion, MIS merged with and colonised a superficial and focally invasive BCC. In the second lesion, MIS merged with an AK. No separate invasive nests of malignant melanoma were seen in either specimen. The atypical melanocytes were highlighted by Melan-A and HMB-45 immunostaining, whereas the epithelial cells in both the BCC and AK stained with the pancytokeratin MNF-116. The patient had a previous history of multiple MMs and non-melanomatous skin cancers and finally developed widespread metastatic malignant melanoma, which proved fatal. The rare and interesting phenomenon of collision tumours may pose diagnostic difficulties. To our knowledge, this is the first reported simultaneous presentation of cytologically malignant collision tumours in a patient with XPV.

Background: There is often a delay between the clinical emergence of a basal cell carcinoma (BCC) and the point in time at which the patient presents for definitive diagnosis and treatment. Previously published studies on delays regarding skin cancer have focused on melanoma rather than Bcc. We conducted a study aimed at identifying factors associated with the detection of Bcc and reasons for the delay in diagnosis. Method: A monocentric study was performed. Patients with a primary BCC diagnosed in 2010 were included in the study. They were asked about factors concerning BCC awareness and detection, tumor characteristics, previous history of nonmelanoma cutaneous cancer, family history of nonmelanoma cutaneous cancer, and the presence of comorbidities. Data were analyzed using SPSS software. Results: The mean diagnostic delay for BCC in our hospital setting was estimated at 19.79 ± 14.71 months. Delayed diagnosis was significantly associated with patients over 65 years, those without a previous history of BCC, those without a family history of BCC, those with BCC located elsewhere than the head or neck, and those with lesions not associated with itching or bleeding. Conclusion: This study revealed considerable delay in the diagnosis of BCC. The main reason for delay in the diagnosis seems to be the initial decision of the patient to seek medical advice. These data suggest a need for greater information for the general public on the symptoms and signs that should prompt suspicion of a BCC.

Basal cell carcinoma originates from pluripotent cells of basal layer of epiderm, external covering of hair follicles, sebaceous glands or other skin adnexa. It is characterized by local infiltrating and sometimes destructive growth. There are several types of basal cell carcinomas that may be manifested in over 12 clinical forms. Surgical treatment depends to a large extent on the histological type, localization and its clinical manifestation. The analysis included 250 patients of both gender and different age, operated for basal cell carcinoma. Clinical characteristics of basal cell carcinoma and the width of the excision were described. It was concluded that the width of the excision of basal cell cancer was in relation to histological type. .

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.
