Basal cell carcinoma with compromised margins: retrospective study of management, evolution, and prognosis

Abstract Background: Non-melanoma skin cancer is the most common type of malignancy in the Western world, and surgical excision is the preferred approach. The approach adopted in the face of incomplete excisions of basal cell carcinoma is still controversial. Objectives: To compare the number of tumor recurrences after treatment for incompletely excised basal cell carcinoma. Methods: Selection and statistical analysis of medical records of patients who had compromised margins after excision of basal cell carcinoma in a tertiary hospital from 2008 to 2013. Results: A total of 120 medical records were analyzed; the mean age was 69.6 years, and 50% of the patients were female. The most prevalent histological type was nodular; the mean size was 1.1 cm, and the tumor location with the highest incidence was the nose. The lateral margin was the most frequently positive. Clinical follow-up was more widely adopted; only 40 patients underwent a second surgery. The total number of patients who had tumor recurrence was 34 (28.3%). Only the malar location significantly influenced the incidence of recurrence (p = 0.02). The mean follow-up time was 29.54 months, with no significant difference between the follow-ups, although 32.9% of the patients followed-up clinically showed recurrence, against only 20% of those who underwent a second surgery. Study limitations: Mean follow-up time of less than five years and sample size. Conclusions: The presence of compromised margins does not necessarily imply recurrence. Location, tumor size, histological subtype, previous epithelial tumors, and clinical conditions of the patient must be considered when choosing the best treatment option.

Recurrence rate of basal cell carcinoma in patients submitted to skin flaps or grafts

Abstract: Background: Basal cell carcinoma is the most common type of skin cancer. Although the literature provides a great deal of information on the recurrences of basal cell carcinoma, studies about these indices addressing only the cases in which flaps and/or grafts have been performed for surgical reconstruction of the excision of this tumor are still lacking. Objectives: To evaluate rates of recurrence of basal cell carcinoma submitted to conventional surgery with pre-established margins and reconstruction by flaps or grafts. Methods: A retrospective and observational study was performed through the analysis of 109 patients, who met inclusion criteria with 116 basal cell carcinomas submitted to conventional surgery and pre-established safety margins, requiring reconstruction through a graft or cutaneous flap. This work was performed the small surgeries sector of Dermatology of the Specialty Outpatient Clinic of the University Hospital of the State University of Londrina, between January 1, 2011 and December 31, 2015. The following data were collected and inserted in an Excel worksheet: name, registration number of the hospital patient, sex, age, tumor location, histopathological type of BCC, procedure performed (type of flap and/or graft), follow-up time, recurrence. Results: Of the 116 procedures, there were recurrences in 3 cases (2.6%) that were located in the nasal region and related to sclerodermiform or micronodular histological types. Study limitations: Retrospective nature of the study. Conclusion: The present study of the dermatology department of this university hospital showed a low rate of recurrence of basal cell carcinoma in cases where flaps and/or grafts were used in the surgical reconstruction.

Skin cancer incidence in rural workers at a reference hospital in western Paraná

Abstract BACKGROUND: Skin cancer is common in Brazil and is related to sun exposure, among other risk factors. There are no data on the incidence of malignant skin neoplasm in rural workers in western Paraná. OBJECTIVE: To analyze the incidence and profile of rural workers who were diagnosed with skin cancer at a reference service in Cascavel, western Paraná, in the last five years (2011-2016). METHODS: This retrospective cross-sectional study was carried out through a review of the anatomopathological reports of rural workers diagnosed with skin cancer at Cascavel Oncology Center (CEONC), in Cascavel. The following variables were collected: year of diagnosis, age, gender, injury location and histological subtype. RESULTS: A total of 681 cases of malignant epithelial neoplasia were identified, with a higher frequency in the 61-70 age group. Data analysis showed an increase of about 210% in the occurrence of skin cancers in the last 5 years. The cephalic region was the most affected, and the most common histological subtype was nodular basal cell carcinoma. There was no association between gender and location. STUDY LIMITATIONS: This is a retrospective study and analysis of a secondary data bank. CONCLUSION: This study is a regional estimation of the incidence of cutaneous neoplasms and provides evidence of a considerable increase in the number of diagnoses in rural workers from western Paraná, Brazil. Moreover, it is possible to conclude that the sample group studied is at risk of developing skin cancer.

Study of skin neoplasms in a university hospital: integration of anatomopathological records and its interface with the literature

Abstract: Background: Skin cancer is a highly prevalent condition with a multifactorial etiology resulting from genetic alterations, environmental and lifestyle factors. In Brazil, among all malignant tumors, skin cancers have the highest incidences. Objective: To retrospectively evaluate the incidence, prevalence and profile of basal cell carcinoma, squamous cell carcinoma and cutaneous melanoma in Campos dos Goytacazes and region. Methods: In total, 2,207 histopathological reports of a local reference hospital were analyzed between January 2013 and December 2015, of which 306 corresponded to the neoplasms studied. Results: Of the 306 reports evaluated, 232 basal cell carcinomas (75.9%), 55 squamous cell carcinomas (18%) and 19 cutaneous melanomas (6.5%) were identified. The face was the most involved anatomical site (58.8%) and women (51%) were the most affected gender. The temporal analysis revealed a decrease in the overall incidence of 3.4% from 2013 to 2014 and 5.4% from 2014 to 2015. There was a 10.1% increase in basal cell carcinomas and 38% in melanomas in this period; however, there was a decrease in the number of squamous cell carcinomas of 14.8% during the studied years. Study limitations: Some samples of cutaneous fragments had no identification of the anatomical site of origin. Conclusion: Research that generates statistical data on cutaneous tumors produces epidemiological tools useful in the identification of risk groups and allows the adoption of more targeted and efficient future prevention measures.

Epidemiological profile of elderly patients with non-melanoma skin cancer seen at the dermatology outpatient clinic of a public hospital

Abstract: Basal cell carcinoma and Squamous cell carcinoma, referred to as non-melanoma skin cancer, are the most common malignancies in humans. Their incidence is increasing worldwide every year. In Brazil, even with the advent of educational campaigns on photoprotection and laws that banned tanning beds, they are the most frequent neoplasias, representing a public health problem recognized by the Ministry of health.

Study of factors affecting the incidence of skin cancer in patients after liver transplant

Abstract: Background: Many factors are currently being identified as potential inductors of skin cancer in patients after a liver transplant, among them, immunosuppressive regimen. Objective: To study the factors that influence the incidence of skin cancer in patients after liver transplant. Methods: We have carried out a retrospective and observational study with 170 transplanted patients who had undergone transplantation from 1997 to 2010. We have adjusted the multiple logistic regression model (saturated model) to the ensemble of collected data using skin cancer as dependent variable, indicated in anatomopathological analysis between 1997 and 2014. Results: Incidence of skin cancer was 9.4%. Predictors were incidence of diabetes in the third year after the transplantation (p=0.047), not using tacrolimus in the first year after the transplantation (p=0.025) and actinic keratosis (p=0.003). Study Limitations: An important limitation is that the interpretation of the results was based on information collected of patients undergoing transplantation at a single center. Future research, multicentric and involving larger and more diverse populations, are needed. Conclusions: Factors found might contribute to Brazilian surveillance programs associated with decreased incidence of skin cancer.

Profile of skin cancer in Pomeranian communities of the State of Espírito Santo / Panorama do câncer da pele em comunidades de imigrantes Pomeranos do Estado do Espírito Santo

ABSTRACT Objectives: to evaluate the profile of skin cancer in Pomeranian communities of the State of Espírito Santo, composed of descendants of European immigrants, regarding gender and age at diagnosis, lesion size and histological type. Method: we studied histopathological reports of 3,781 patients operated between 2000 and 2010, with resection of 4,881 lesions. We assessed histological type, lesion size, age and gender of the patients at diagnosis and their correlations in the 11-year period. Results: the histopathological examination revealed basal cell carcinoma in 3,159 patients (83.5%), squamous cell carcinoma in 415 (11%), melanoma in 64 (1.7%), and 143 patients (3.8%) had combined lesions of basal cell carcinoma and squamous cell carcinoma. As to size, 47.1% measured between 5.1 and 10mm. The age group of 61 to 70 years was the one that sustained the largest number of surgical interventions (24.3%). There was a predominance of the female gender (2,027, 53.6%) in relation to the male (1,754, 46.4%). Conclusion: basal cell carcinoma was the most frequent histological type. The prevalences of squamous cell carcinoma and melanoma were below the national estimate of the National Cancer Institute. The diagnosis of tumors occurred at more advanced ages (above 60 years) and there was an increase in the incidence and size of skin tumors in the male population.

RESUMO Objetivos: avaliar o panorama do câncer de pele em comunidades pomeranas do Estado do Espírito Santo, compostas por descendentes de imigrantes europeus, quanto ao sexo e idade ao diagnóstico, tamanho da lesão e tipo histológico. Método: foram avaliados laudos histopatológicos de 3781 pacientes operados entre os anos de 2000 e 2010, com ressecção de 4881 lesões. Foram avaliados tipo histológico, tamanho das lesões, idade e sexo dos pacientes ao diagnóstico e suas correlações no período de 11 anos. Resultados: o exame histopatológico evidenciou carcinoma basocelular em 3159 pacientes (83,5%), carcinoma espinocelular em 415 (11%), melanoma em 64 (1,7%) e 143 pacientes (3,8%) apresentaram lesões combinadas de carcinoma basocelular e carcinoma espinocelular. Quanto ao tamanho, 47,1% media entre 5,1 e 10 mm. O grupo etário de 61 aos 70 anos foi o que sofreu o maior número de intervenções cirúrgicas (24,3%). Houve predomínio do sexo feminino (53,6%, n=2027) em relação ao masculino (46,4%, n=1754). Conclusão: o carcinoma basocelular foi o tipo histológico mais frequente. As prevalências do carcinoma espinocelular e do melanoma se situaram abaixo da estimativa nacional do Instituto Nacional de Câncer. O diagnóstico dos tumores ocorreu em idades mais avançadas (acima de 60 anos) e houve aumento da incidência e dimensões dos tumores de pele na população masculina.

Initial basal cell carcinomas diagnosed in the National Campaign for Skin Cancer Prevention are smaller than those identified by the conventional medical referral system

Abstract: BACKGROUND: Basal cell carcinoma is the malignant tumor most often diagnosed in the National Campaign for Skin Cancer Prevention (NCSCP). Little is known about the profile of these lesions compared to the profile of lesions diagnosed by conventional routes of public dermatological care. OBJECTIVE: To identify if basal cell carcinomas identified in prevention campaigns and referred to surgery are smaller than those routinely removed in a same medical institution. METHODS: Cross-sectional study including tumors routed from 2011-2014 campaigns and 84 anatomopathological reports of outpatients. RESULTS: The campaigns identified 223 individuals with suspicious lesions among 2,531 examinations (9%), with 116 basal cell carcinomas removed. Anatomopathological examinations revealed that the primary lesions identified in the national campaigns were smaller than those referred to surgery by the conventional routes of public health care (28 [13-50] x 38 [20-113] mm2, p <0.01). On the other hand, after a mean follow-up of 15.6 ± 10.3 months, 31% of cases identified in campaigns showed new basal cell carcinoma lesions. STUDY LIMITATIONS: Retrospective study and inaccuracies in the measurements of the lesions. CONCLUSIONS: The NCSCP promotes an earlier treatment of basal cell carcinomas compared to patients referred to surgery by the conventional routes of public health care, which can result in lower morbidity rates and better prognosis.

Non-melanoma skin cancer in Portuguese kidney transplant recipients - incidence and risk factors

Abstract: Background: Cancer is currently among the three leading causes of death after solid organ transplantation and its incidence is increasing. Non-melanoma skin cancer - squamous cell carcinoma and basal cell carcinoma - is the most common malignancy found in kidney transplant recipients (KTRs). The incidence of non-melanoma skin cancer in KTRs has not been extensively studied in Portugal. Objectives: To determine the incidence of non-melanoma skin cancer in KTRs from the largest Portuguese kidney transplant unit; and to study risk factors for non-melanoma skin cancer. Methods: Retrospective analysis of clinical records of KTRs referred for the first time for a dermatology consultation between 2004 and 2013. A case-control study was performed on KTRs with and without non-melanoma skin cancer. Results: We included 288 KTRs with a median age at transplantation of 47 years, a male gender predominance (66%) and a median transplant duration of 3.67 years. One fourth (n=71) of KTRs developed 131 non-melanoma skin cancers, including 69 (53%) squamous cell carcinomas and 62 (47%) basal cell carcinomas (ratio squamous cell carcinoma: basal cell carcinoma 1.11), with a mean of 1.85 neoplasms per patient. Forty percent of invasive squamous cell carcinomas involved at least two clinical or histological high-risk features. The following factors were associated with a higher risk of non-melanoma skin cancer: an older age at transplantation and at the first consultation, a longer transplant duration and the presence of actinic keratosis. KTRs treated with azathioprine were 2.85 times more likely to develop non-melanoma skin cancer (p=0.01). Conclusion: Non-melanoma skin cancer was a common reason for dermatology consultation in Portuguese KTRs. It is imperative for KTRs to have access to specialized dermatology consultation for early referral and treatment of skin malignancies.

Análise do tratamento do carcinoma basocelular / Analysis of basal cell carcinoma treatment

Introdução: O câncer de pele na população brasileira é a neoplasia mais comum. Localiza-se com mais frequência na face, causando morbidade tanto funcional quanto estética aos pacientes. O tratamento consiste na ressecção oncológica da lesão, preservando a função com a menor deformidade possível. O câncer de pele mais comum é o carcinoma basocelular (CBC), correspondendo entre 70-80% dos casos. Método: Avaliamos retrospectivamente 73 pacientes com 95 carcinomas basocelulares no período de março de 2010 a maio de 2012. Foram analisados os seguintes critérios: idade, sexo, cor, comorbidades, exposição solar, presença de consulta prévia com dermatologia, localização da lesão, tamanho da lesão, tipo clínico, tipo histológico, tipo de reconstrução, complicações cirúrgicas, margem cirúrgicas, conduta na margem cirúrgica comprometida, anatomopatológico após reintervenção, presença de recidiva e aparecimento de outra lesão primária no mesmo paciente. Resultados: A idade média foi de 60,73 anos. O sexo feminino correspondeu a 56,16%. A Exposição solar foi referida em 73,97% dos casos. O tamanho médio da lesão foi 0,91 cm. O local mais frequente foi a face (71,58%). O retalho local foi utilizado em 54,74% dos casos. O CBC sólido circunscrito foi o mais frequente. As margens comprometidas ocorreram em 8,42% dos casos, demonstrando relação com lesões maiores de 2cm e com o nariz sem significância estatística. Conclusão: No tratamento do carcinoma basocelular é importante a participação do cirurgião plástico, objetivando a ressecção sob princípios oncológicos, realizando a reparação da área afetada, a manutenção funcional e a menor alteração estética possível.

Introduction: Skin cancer is the most common neoplasm in the Brazilian population. It most frequently presents on the face, causing functional and aesthetic morbidity in patients. Its treatment consists in resection of the lesion while preserving the skin's function with the least possible deformity. The most common skin cancer is basal cell carcinoma (BCC), representing 70­80% of all cases. Methods: We retrospectively evaluated 73 patients with 95 BCCs from March 2010 to May 2012. The following characteristics were analyzed: age, sex, skin color, comorbidities, sun exposure, prior dermatological consultation, lesion site, lesion size, clinical type, histological type, reconstruction type, surgical complications, surgical margins, management of compromised surgical margins, anatomical pathology after reintervention, recurrence, and appearance of another primary lesion in the same patient. Results: The mean age of the patients was 60.73 years. Female patients accounted for 56.16%. Sun exposure was reported in 73.97% of patients. The mean lesion size was 0.91 cm, and the most common lesion site was the face (71.58%). A local flap was used in 54.74% of cases. Circumscribed solid BCC was the most common type. Compromised margins occurred in 8.42% of cases, demonstrating a relation between lesions >2 cm and the nose but without statistical significance. Conclusion: The plastic surgeon plays an important role in the treatment of BCC, aiming to perform resection following oncological principles, repair the affected area, and maintain the skin's functionality with the least possible cosmetic alterations.

Differences in age and topographic distribution of the different histological subtypes of basal cell carcinoma, Taubaté (SP), Brazil / Diferencas na idade e distribuicao topografica dos diferentes subtipos histologicos de carcinoma basocelular, Taubate (SP), Brasil

BACKGROUND: Basal cell carcinoma is the most common form of cancer in humans. OBJECTIVES: To identify the epidemiology of basal cell carcinoma in Taubaté-SP and verify a possible association between topography and the different histological subtypes of this tumor. METHODS: This was a cross-sectional study conducted at The University Hospital of Taubaté between 01/01/08 and 12/31/09. The study included patients with a confirmed diagnosis of basal cell carcinoma, of both genders, without age restrictions. The variables studied were incidence of basal cell carcinoma, topography, histological subtype, skin color, age and gender. We employed the chi-square test to identify the association between histological subtype and topography, and the student's t test to compare the mean age of onset for the different histological subtypes. RESULTS: The study included 239 individuals. The mean age of the sample was 68.0 years. Male subjects (57.7%) and whites (87.1%) predominated in the study. The predominant histological subtype was nodular (34.7%), followed by the superficial subtype. The most frequent sites of involvement were the head and neck (areas exposed to light), with predominance of the nasal region. The superficial subtype was an exception, as it showed a strong association with unexposed areas like the trunk. The mean age of onset of superficial basal cell carcinoma also differed from that of the other histological subtypes, 63.0 and 69.0 years, respectively. CONCLUSION: The results of this study suggest an association of the superficial histological subtype with younger patients and unexposed areas of the body, linking this type of tumor with a pattern of intermittent sun exposure, more similar to the standard photocarcinogenesis of melanoma. .

Spectrum of periorbital dermatoses in South Indian population.

Background: Periorbital dermatoses are very common dermatological disorders which pose a diagnostic and therapeutic challenge for the treating dermatologist due to the similarity of symptoms in this area. Aims: To study the spectrum of periorbital dermatoses and to assess the association of systemic diseases with periorbital dermatoses. Methods: This was a hospital based descriptive study done on 250 consecutive patients irrespective of their age and sex who attended the Dermatology out patient department (OPD), with dermatological conditions pertaining to the periorbital area over a period of 2 years from October 2010 to September 2012. Results: The most common dermatological conditions seen in the periorbital region were benign and malignant skin tumors observed in 63 (25.2%) cases, followed by the disorders of pigmentation in 51 (20.4%) and eczema in 44 cases (17.6%), infections in 33 (13.2%) cases and nevoid conditions in 26 (10.4%) cases. Certain periorbital dermatoses were significantly more in females than in males in the present study like skin tags, connective tissue diseases, and periorbital melanosis (POM). Some periorbital dermatoses were significantly more common in older age group such as seborrheic keratoses, skin tags and airborne contact dermatitis whereas infections, syringomas, allergic contact dermatitis and atopic dermatitis were more prevalent in younger age group. Syringomas and POM were more common in middle-aged women. Conclusions: The most common dermatological condition seen in the periorbital region in this study are benign skin tumors (keratosis and skin tags), followed by the disorders of pigmentation and eczema, infections and nevoid conditions.

INTRODUCTION: Basal cell carcinoma (BCC) is the most common malignancy in the human population. There has been an increased incidence in all countries, including Chile. BCC is a clinically and histologically heterogeneous tumor. The main risk factor of BCC is the ultraviolet radiation exposure. In Chile, in the last decade, there have been numerous campaigns of skin cancer prevention and early detection of this neoplasm. The purpose of this paper is to compare the behavior of BCC in relation to demographic, clinical and histological parameters in two periods, 1995-1999 and 2005-2009 in the population of four hospitals in Santiago de Chile…

Caracterización clinicoepidemiológica de pacientes con tumores palpebrales malignos / Clinical and epidemiological characterization of patients with malignant eyelid tumors

Se efectuó un estudio observacional, descriptivo y transversal de 61 pacientes con tumores palpebrales malignos, atendidos en la consulta de Oftalmología del Instituto Nacional de Oncología y Radiobiología de Ciudad de La Habana, durante el 2011, a fin de caracterizarles según variables clinicoepidemiológicas de interés para la investigación. En la serie, los más afectados fueron el sexo masculino (68,6 por ciento) y los pacientes de piel blanca (86,9 por ciento); predominaron el grupo etario de 61-70 años (37,0 por ciento), el carcinoma basocelular como el tumor palpebral maligno más frecuente (73,8 por ciento) y la agricultura como la labor fundamental que realizaban los enfermos (67,2 por ciento)

An observational, descriptive and cross-sectional study was conducted in 61 patients with malignant eyelid tumors, treated at the Ophthalmology Department of the National Institute of Oncology and Radiobiology, Havana, during 2011, in order to characterize them according to clinical and epidemiological variates of interest to research. Male sex (68.6 percent) and white patients (86.9 percent) were the most affected in the series. Also, the age group of 61-70 years (37.0 percent), basal cell epithelioma as the most frequent malignant eyelid tumor (73.8 percent) and agriculture as the essential work performed by patients (67.2 percent) prevailed

Epidemiology of basal cell carcinomas and squamous cell carcinomas in a Department of Dermatology: a 5 year review / Epidemiologia dos carcinomas basocelulares e espinhocelulares em um Serviço de Dermatologia: revisão de 5 anos

BACKGROUND: Non-melanoma skin cancer, a common designation for both basal cell carcinomas and squamous cell carcinomas, is the most frequent malignant skin neoplasm. OBJECTIVE: Epidemiologic characterization of the population with Non-melanoma skin cancer. METHODS: Retrospective analysis of all patients diagnosed with Non-melanoma skin cancer based on histopathologic analysis of all incisional or excisional skin biopsies performed between 2004 and 2008 in a Department of Dermatology. RESULTS: A total of 3075 Non-melanoma skin cancers were identified, representing 88% of all malignant skin neoplasms (n=3493) diagnosed in the same period. Of those, 68,3% were basal cell carcinomas. Most Non-melanoma skin cancer patients were female and over 60 years old. Of all Non-melanoma skin cancer, 81,7% (n=1443) were located in sun-exposed skin, and represented 95,1% of malignant skin neoplasms in sun-exposed skin. Non-melanoma skin cancer was the most frequent malignant skin neoplasm in most topographic locations, except for abdomen and pelvis - over 95% of all malignant skin neoplasms in the face, neck and scalp were Non-melanoma skin cancer. Basal cell carcinomas were clearly predominant in all locations, except in upper and lower limbs, lower lip and genitals, where squamous cell carcinomas represented respectively 77,7%, 77,4%, 94,7% and 95,3% of the Non-melanoma skin cancers. CONCLUSION: Being the most common skin cancer, Non-melanoma skin cancer should be under constant surveillance, in order to monitor its epidemiologic dynamics, the efficiency of preventive measures and the adaptation of the healthcare resources.

FUNDAMENTOS: O cancro cutâneo não-melanoma, designação conjunta para os carcinomas basocelulares e espinhocelulares, é o tipo de neoplasia cutânea maligna mais frequente. OBJETIVOS: Caracterização epidemiológica da população diagnosticada com cancro cutâneo não-melanoma. MÉTODOS: Foi realizada uma análise retrospectiva dos doentes portadores de cancro cutâneo não-melanoma identificados por análise histológica de todas as biopsias cutâneas incisionais ou excisionais ao longo de 5 anos (2004-2008) num serviço de Dermatologia. RESULTADOS: foram identificados 3075 cancros cutâneos não-melanoma, representando 88% do total de neoplasias malignas diagnosticadas no mesmo período (n=3493). Destes, 68,3% eram carcinomas basocelulares. No seu conjunto, a população de cancro cutâneo nãomelanoma era predominantemente constituída por indivíduos idosos e do sexo feminino, tendo sido observado um aumento consistente da freqüência ao longo do período avaliado (5,25%/ano). A maioria dos cancros cutâneos não-melanoma (n=1443, 81,7%) foi identificada nas áreas de pele foto-exposta, representando 95,1% de todas as neoplasias malignas em áreas foto-expostas. O cancro cutâneo não-melanoma foi a neoplasia mais representativa na generalidade das áreas topográficas, à exceção do abdômen e da pélvis, representando, em particular, mais de 95% das neoplasias malignas da face, da região cervical e do couro cabeludo. O carcinoma basocelular foi o cancro cutâneo não-melanoma predominante em todas as localizações, à exceção dos membros inferiores e superiores, lábio inferior e da área genital, onde o carcinoma espinhocelular representou, respectivamente, 77,7%, 77,4%, 94,7% e 95,3% dos casos. CONCLUSÕES: O cancro cutâneo não-melanoma, como neoplasia maligna cutânea mais freqüente, deverá ser alvo de uma monitorização regular, com vista à determinação da sua dinâmica epidemiológica, da eficácia das medidas preventivas e adequação dos recursos de saúde.
