Selective Neck Dissection for Node-Positive Oral Cavity Squamous Cell Carcinoma: A Retrospective Cohort Study

Abstract Introduction Selective neck dissection inclinically node-negative neckisconsidered the standard of care for oral squamous cell carcinomas (SCCs). Controversy still prevailsinnode-positive disease regarding the extent of neck dissection. In our part of the world, comprehensive neck dissection is mostly considered to be the minimal optimal treatment for palpable neck disease. Objective To compare regional control and disease-specific survival between clinically node-positive and node-negative patients undergoing selective neck dissection for oral SCC. Methods This was a retrospective cohort study conducted in the department of ENT, Head and Neck surgery at a tertiary care hospital. All patients with biopsy-proven oral and lip SCC, with or without nodal disease, who underwent selective neck dissection between April 2006 and July 2015 were included in the study. Results During the study period, 111 patients with oral SCC underwent selective neck dissection, of whom 71 (62%) were clinically node-negative and 40 (38%) patients had clinically positive nodes in the neck. The mean follow-up was 16.62 months (standard deviation [SD]: 17.03). The overall regional control rates were 95 versus 96% for clinical negative versus positive nodes, respectively (p = 0.589). The disease-specific survival was 84.5% in the node negative group versus 82.5% in the node-positive group (p = 0.703). Conclusion Selective neck dissection in node-positive neck oral SCC has similar regional control rates when compared with node-negative neck SCC. The difference in disease-specific survival between the two groups is also not significant.

Effect of ribociclib on productivity losses due to breast cancer in young women in Brazil

ABSTRACT OBJETIVE To evaluate the effect of ribociclib versus endocrine therapy on productivity losses due to advanced breast cancer. METHODS Productivity data from the MONALEESA-7 trial, obtained from the results of the application of the Work Productivity and Activity Impairment (WPAI) questionnaire on progression-free survival state (43-month follow-up), were extrapolated to the 10,936 Brazilian prevalent cases of premenopausal women with hormone receptor positive/human epidermal growth factor receptor 2 negative (HR+/HER2-) breast cancer. Productivity loss was determined by quantifying the economic costs of workforce dropout over time in both treatment arms and by discounting the economic costs of absenteeism and presenteeism from workforce retention. A human capital approach was used. RESULTS Net productivity gains in the ribociclib arm were estimated at USD 4,285,525.00, representing 316,609 added work hours over 43 months and a mean of 2,009 added work weeks per year. CONCLUSIONS The phase III MONALEESA-7 trial productivity results applied to the Brazilian premenopausal prevalent cases of hormone receptor positive/human epidermal growth factor receptor 2 negative (HR+/HER2-) breast cancer showed that treatment with ribociclib + endocrine therapy improves workforce participation compared with endocrine therapy alone in premenopausal women with hormone receptor positive/human epidermal growth factor receptor 2 negative (HR+/HER2-) metastatic breast cancer, with potential economic gains for the Brazilian society.

El Hybrid-APC en el tratamiento endoscópico del esófago de Barrett / The Hybrid-APC in the endoscopic treatment of Barrett'sesophagus

RESUMEN Fundamento: debido al riesgo de evolución insatisfactoria de los pacientes con esófago de Barrett hacia el adenocarcinoma esofágico, es necesaria la aplicación de técnicas seguras y efectivas que logren prevenir el desenlace hacia lesiones malignas esofágicas. El Hybrid-APC (Argón plasma coagulación) es una de estas técnicas que permiten detener la historia natural del esófago de Barrett en su etapa inicial. Objetivo: realizar una revisión y reflexión acerca del tratamiento endoscópico del esófago de Barrett con el Hybrid-APC. Métodos: se realizó una búsqueda en los motores Google, PudMed, SciELO regional, SciELO Public Health, National Library of Medicine PudMed. En la estrategia de la búsqueda se utilizaron los términos: esófago de Barrett, tratamiento endoscópico, Hybrid-APC. Se evaluaron los documentos en extensos y se desarrolló un documento resumen de la información recolectada. En la búsqueda bibliográfica realizada se encontraron 20 trabajos relacionados con esófago de Barrett, tratamiento endoscópico 10 y específico del uso del Hybrid-APC cinco. Resultados: los estudios reportaron la efectividad y seguridad de la ablación con el Hybrid-APC en el tratamiento endoscópico del esófago de Barrett con displasia de bajo grado; y en la displasia de alto grado y carcinoma in situ remanente, luego de una resección mucosa endoscópica. Conclusiones: el tratamiento endoscópico del esófago de Barrett con Hybrid-APC, se considera una técnica alternativa para detener la evolución de esta enfermedad hacia el adenocarcinoma. Esto generará motivación para entrenamientos y su puesta en práctica de forma generalizada.

ABSTRACT Background: due to the risk of unsatisfactory evolution of patients with Barrett's esophagus (EB) towards esophageal adenocarcinoma, it is necessary to apply safe and effective techniques that prevent the outcome towards esophageal malignant lesions. The Hybrid-APC (argon plasma coagulation) is one of these techniques that allow stopping the natural history of EB in its initial stage. Objective: to conduct a review and reflection on the endoscopic treatment of Barrett's esophagus with the Hybrid-APC. Methods: a search was conducted on Google, PudMed, SciELo regional, SciELo Public Health, National Library of Medicine PudMed engines. The search strategy used the terms: Barrett's esophagus, endoscopic treatment, Hybrid-APC. Extensive documents were evaluated and a summary document of the information collected was developed. The literature search found 20 works related to Barrett's esophagus, ten on endoscopic treatment, and five on specific to the use of Hybrid-APC. Results: studies reported the effectiveness and security of the ablation with the Hybrid-APC in the endoscopic treatment of Barrett's esophagus with low degree dysplasia, and in the high degree dysplasia and remnant carcinoma in situ, after the endoscopic mucous resection. Conclusions: the endoscopic treatment of Barrett's esophagus with Hybrid-APC is considered an alternative technique to stop the evolution of this pathology towards adenocarcinoma. This will generate motivation for training and its implementation in a generalized way.

Evolution of the surgical treatment of lung cancer at a tertiary referral center in Brazil, 2011-2018 / Evolução do tratamento cirúrgico do câncer de pulmão em uma instituição terciária de referência no Brasil, 2011-2018

ABSTRACT Objective: To evaluate the evolution of clinical and epidemiological data, as well as data related to diagnosis, staging, treatment, and survival, among patients undergoing curative surgery for lung cancer at a tertiary referral center in the city of São Paulo, Brazil. Methods: This was a retrospective study of cases in the International Association for the Study of Lung Cancer database. We selected only cases of patients undergoing curative surgery between January of 2011 and April of 2018. We determined overall and disease-free survival at 36 months and compared the data between two periods (2011-2014 and 2015-2018). Results: Comparing the two periods (N = 437 cases), we observed trends toward increases in the number of female patients, as well as in the proportions of former smokers (44.09% vs. 53.59%), of patients diagnosed with adenocarcinoma (52.21% vs. 59.72%), and of patients diagnosed at an earlier pathological stage, together with a decrease in 30-day mortality (4.05% vs. 2.39%). There were significant increases in the proportions of cases diagnosed at an earlier clinical stage (p = 0.002) or incidentally (p = 0.003). Although lobectomy was the main surgical technique employed, there was a proportional increase in segmentectomies (2.67% vs. 7.11%; p = 0.026). Overall and disease-free survival rates were 79.4% (95% CI: 74.0-83.9%) and 75.1% (95% CI: 69.1-80.1%), respectively. The difference in overall survival between the periods lost statistical significance when adjusted for pathological stage, the only factor that affected survival (log-rank: p = 0.038 to p = 0.079). Conclusions: The clinical and epidemiological evolution presented in this study corroborates global trends. The decrease in 30-day mortality was probably due to better patient selection and improved surgical techniques.

RESUMO Objetivo: Avaliar a evolução de dados clínicos e epidemiológicos, assim como dados sobre diagnóstico, estadiamento, tratamento e sobrevida em pacientes submetidos a tratamento cirúrgico curativo de câncer de pulmão em uma instituição terciária na cidade de São Paulo (SP). Métodos: Estudo retrospectivo baseado nos casos inseridos no banco de dados da International Association for the Study of Lung Cancer submetidos à cirurgia curativa entre janeiro de 2011 e abril de 2018. Determinamos a sobrevida global e livre de doença em 36 meses e comparamos os dados em dois períodos (2011-2014 e 2015-2018). Resultados: Comparando-se os dois períodos (N = 437 casos), houve uma tendência de aumento no número de pacientes do sexo feminino, ex-tabagistas (44,09% vs. 53,59%), com diagnóstico de adenocarcinoma (52,21% vs. 59,72%) e em estádio patológico mais precoce, assim como queda da mortalidade em 30 dias (4,05% vs. 2,39%). Houve aumento significativo de casos em estádio clínico mais precoce (p = 0,002) e diagnosticados incidentalmente (p = 0,003). A lobectomia foi a principal técnica cirúrgica; entretanto, houve aumento de segmentectomias (2,67% vs. 7,11%; p = 0,026). As sobrevidas global e livre de doença foram de 79,4% (IC95%: 74,0-83,9%) e 75,1% (IC95%: 69,1-80,1%), respectivamente. Houve perda de significância estatística na sobrevida global entre os períodos quando ajustada por estadiamento patológico, o único fator a impactar a sobrevida (log-rank: p = 0,038 para p = 0,079). Conclusões: A evolução clínica e epidemiológica apresentada neste estudo corrobora tendências mundiais. A diminuição da mortalidade em 30 dias provavelmente ocorreu devido a melhor seleção de pacientes e melhora da técnica cirúrgica.

Novel low-cost approach to the treatment of ocular surface squamous neoplasia using pattern scanning laser photocoagulation / Nova abordagem de baixo custo para neoplasia escamosa da superficie ocular usando fotocoagulação tipo pattern scanning

ABSTRACT Purpose: To evaluate the safety and 12-month effect of treatment with pattern scanning laser photocoagulation for ocular surface squamous neoplasia in a low-resource setting with extremely limited access to an operating room. Methods: Adult patients with a clinical diagnosis of ocular surface squamous neoplasia underwent a complete ophthalmologic examination. After topical anesthesia and instillation of toluidine blue 1%, the lesion was treated using pattern scanning photocoagulation for a duration time that varied from 20 to 100 ms and power from 600 to 1,800 mW. Patients were examined on a weekly basis for the first month and underwent weekly retreatment of the remaining lesions, as necessary. Patients had a minimum follow-up of 12 months. Results: Thirty-eight patients (38 eyes) were included. All patients had clinical ocular surface squamous neoplasia that was confirmed by impression cytology. The age of patients ranged from 40 to 83 years (average: 65.5 years) and 28 of them were males (74%). The patients were divided into two groups: group I (immunocompetent) and group II (immuno­suppressed). In group I, 23 patients (74%) presented complete response with lesion control after laser treatment alone. In group II, two of seven patients (28%) showed treatment response during the follow-up. The average number of treatments was 2.5 (one to six laser treatments). Procedures were well tolerated. Conclusion: Short-term results of the laser photocoagulation approach for the treatment of ocular surface squamous neoplasia conjunctival lesions were favorable, with a 74% success rate observed in immunocompetent patients. This novel strategy is a less resource-intensive alternative that could demonstrate its usefulness in settings with shortages in operating rooms and in recurrent cases. Studies with longer follow-ups and larger sample sizes are warranted to confirm our findings and evaluate the effectiveness of laser treatment in association with topical chemotherapy.

RESUMO Objetivo: Avaliar a segurança e o efeito de 12 meses de tratamento com fotocoagulação pelo pattern scanning laser para neoplasia escamosa da superfície ocular em um ambiente com poucos recursos e acesso extremamente limitado a um tratamento cirúrgico. Métodos: Pacientes adultos com diagnóstico de neoplasia escamosa de superfície ocular foram submetidos a exame oftalmológico completo. Após anestesia tópica e instilação de azul de toluidina 1%, a lesão foi tratada com laser por um tempo de duração que variou de 20 a 100 ms e potência de 600 a 1800 mW. Os pacientes foram examinados semanalmente durante o primeiro mês e fo­ram retratados semanalmente das lesões restantes, conforme necessário. Os pacientes tiveram um seguimento mínimo de 12 meses. Resultados: Trinta e oito pacientes (38 olhos) foram incluídos no estudo. Todos os pacientes apresentaram neoplasia escamosa da superfície ocular clínica, confirmada por citologia de impressão. A idade dos pacientes variou entre 40 e 83 anos (média de 65.5 anos) e 28 deles eram do sexo masculino (74%). Os pacientes foram divididos em dois grupos: Grupo I (imunocompetente) e grupo II (imunossuprimido). No grupo I, 23 pacientes (74%) apresentaram resposta completa com o controle da lesão após o tratamento com laser. No grupo II, dois dos sete pacientes (28%) apresentaram resposta ao tratamento durante o acompanhamento. A média de aplicações de laser foi de 2,5 (1 a 6 aplicações). Os procedimentos foram bem tolerados. Conclusões: Os resultados a curto prazo da abordagem de fotocoagulação a laser para o tratamento das lesões conjuntivais de neoplasia escamosa de superfície ocular foram favoráveis, com uma taxa de sucesso de 74% observada em pacientes imunocompetentes. Essa nova estratégia é uma alternativa menos intensiva em recursos que pode demonstrar sua utilidade em ambientes com escassez de salas cirúrgicas e em casos recorrentes. Estudos com acompanhamentos mais longos e amostras maiores são necessários para confirmar nossos achados e avaliar a eficácia do tratamento a laser asso­ciado à quimioterapia tópica.

RESUMEN Fundamento: el carcinoma escamoso del pene es uno de los tumores menos frecuentes del aparato urogenital, que por su localización trae como consecuencias serias afectaciones de la calidad de vida de los pacientes, ocasiona daños tanto físicos, psíquicos como sexuales, por lo que su prevención resulta muy importante. Objetivo: exponer un caso de cuerno cutáneo peneano por lo poco frecuente de su aparición y de su potencial relacionado con la enfermedad neoplásica, en especial el carcinoma escamoso. Presentación del caso: se presenta el caso de un paciente de 74 años de edad, blanco, jubilado con antecedentes de ser fumador de dos cajetillas de cigarros desde la juventud diariamente, además de presentar hipertensión arterial controlada con tratamiento, que desde hace un año presenta lesión en el glande, indurada no dolorosa que ha ido en aumento, además de secreción con mal olor, la lesión hace relieve, paciente no circuncidado. Conclusiones: la presentación clínica de este tipo de tumores ha variado de manera sustancial al asemejarse en ocasiones lesiones benignas, por ello el diagnóstico y tratamiento de esta enfermedad suelen retrasarse implicando un menor tiempo en la supervivencia de los pacientes.

ABSTRACT Background: scamous cell carcinoma of the Penis is one of the less frequent tumors of the urogenital apparatus, which due to its location has serious consequences for the quality of life of patients, causing physical, psychological and sexual damage, so that its prevention is very important. Objective: to present a case of cutaneous penis horn due to infrequency of its appearance and its potential related to neoplastic disease, especially squamous carcinoma. Case report: 74-year-old patient, retiree with antecedents of being an inveterate smoker of two daily packets since youth, and hypertension controlled with treatment, who presented 1 year ago a glans lesion, indurated painless that has been increasing, as well as discharge with a bad odor, the lesion is protruded, not circumcised patient. Conclusions: the clinical presentation of this type of tumors has varied substantially resembling sometimes benign lesions, so the diagnosis and treatment of this disease are usually delayed implying a shorter time in the survival of patients.

Influence of time between surgery and postoperative radiation therapy and total treatment time in locoregional control of patients with head and neck cancer: a single center experience

OBJECTIVE: This study aimed to evaluate the effect of the delay to initiate postoperative radiation therapy (RT) on locoregional control to head and neck squamous cell carcinoma patients. METHODS: Retrospective cohort study that included patients submitted to surgery followed by adjuvant RT (with/without chemotherapy). The time interval between surgery and RT was dichotomized by the receiver operating characteristics curve method at 92 days. Other possible sources of heterogeneity with potential impact on locoregional control were explored by regressive analysis. RESULTS: A total of 168 patients were evaluated. The median time for locoregional recurrence (LRR) was 29.7 months. The relapse-free survival rates were 66.4% and 75.4% for patients who initiated RT more than and within 92 postoperative days (p=0.377), respectively. Doses lower than 60Gy were associated with worse rates of locoregional control (HR=6.523; 95%CI:2.266-18.777, p=0.001). Patients whose total treatment time (TTT) was longer than 150 days had LRR rate of 41.8%; no patient with TTT inferior to 150 days had relapses (p=0.001). CONCLUSIONS: The interval between surgery and RT did not show influence on locoregional control rates. However, doses <60Gy and the total treatment time >150 days were associated with lower locoregional control rates.

Tumor-node-metastasis staging and treatment patterns of 73, 167 patients with lung cancer in Brazil / Estadiamento tumor-nódulo-metástase e padrão de tratamento oncológico de 73. 167 pacientes com câncer de pulmão no Brasil

ABSTRACT Objective: To characterize the clinical and histological profile, as well as treatment patterns, of patients with early-stage, locally advanced (LA), or advanced/metastatic (AM) lung cancer, diagnosed between 2000 and 2014, in Brazil. Methods: This was an analytical cross-sectional epidemiological study employing data obtained for the 2000-2014 period from the hospital cancer registries of two institutions in Brazil: the José Alencar Gomes da Silva National Cancer Institute, in the city of Rio de Janeiro; and the São Paulo Cancer Center Foundation, in the city of São Paulo. Results: We reviewed the data related to 73,167 patients with lung cancer. The proportions of patients with early-stage, LA, and AM lung cancer were 13.3%, 33.2%, and 53.4%, respectively. The patients with early-stage lung cancer were older and were most likely to receive a histological diagnosis of adenocarcinoma; the proportion of patients with early-stage lung cancer remained stable throughout the study period. In those with LA lung cancer, squamous cell carcinoma predominated, and the proportion of patients with LA lung cancer decreased significantly over the period analyzed. Those with AM lung cancer were younger and were most likely to have adenocarcinoma; the proportion of patients with AM lung cancer increased significantly during the study period. Small cell carcinoma accounted for 9.2% of all cases. In our patient sample, the main treatment modality was chemotherapy. Conclusions: It is noteworthy that the frequency of AM lung cancer increased significantly during the study period, whereas that of LA lung cancer decreased significantly and that of early-stage lung cancer remained stable. Cancer treatment patterns, by stage, were in accordance with international guidelines.

RESUMO Objetivo: Caracterizar o perfil clínico e histológico, assim como o de tratamento oncológico, de pacientes com câncer de pulmão nos estádios precoce, localmente avançado (LA) e avançado/metastático (AM), diagnosticados entre 2000 e 2014 no Brasil. Métodos: Estudo epidemiológico transversal analítico com dados brasileiros obtidos de registros hospitalares de câncer do Instituto Nacional de Câncer José Alencar Gomes da Silva, localizado na cidade do Rio de Janeiro, e da Fundação Oncocentro de São Paulo, localizada na cidade de São Paulo, de 2000-2014. Resultados: Foram avaliados 73.167 pacientes com câncer de pulmão. As proporções de pacientes nos estádios precoce, LA e AM foram de 13,3%, 33,2% e 53,4%, respectivamente. Os pacientes em estádio precoce apresentavam idade mais avançada, adenocarcinoma como tipo histológico predominante e frequência estável ao longo do período do estudo; aqueles em estádio LA apresentaram mais frequentemente carcinoma de células escamosas, havendo uma redução significativa de sua frequência relativa no período do estudo; e aqueles em estádio AM tinham idade menor, predominância de adenocarcinoma, com um significativo aumento da sua frequência no período. O carcinoma de células pequenas correspondeu a 9,2% dos casos. A quimioterapia foi a principal modalidade de tratamento utilizada. Conclusões: A frequência do estádio AM mostrou estar em aumento durante o período de estudo, concomitantemente a uma expressiva redução na frequência do estádio LA e estabilidade do estádio precoce. O padrão de tratamento oncológico esteve em conformidade com as diretrizes internacionais de acordo com o estadiamento.

Clinical pathways of breast cancer patients treated in the Federal District, Brazil / Itinerário terapêutico de mulheres com câncer de mama tratadas no Distrito Federal, Brasil

ABSTRACT OBJECTIVE: To identify the clinical pathways of women with breast cancer treated in public hospitals, and to analyze the factors that influence the time interval between the first appointment and the start of therapy. METHODS: A cross-sectional study was conducted with 600 women with breast cancer treated in nine public hospitals in the Brazilian Federal District. Patients were interviewed between September 2012 and September 2014. Simple and multiple logistic regression models were adjusted to evaluate the variables associated with the time interval studied. The most frequent pathway was the one that started in primary care with following care in the therapy service (28.9%). In the multiple adjustment, factors associated to a longer time interval between the first appointment and therapy were: lower family income (OR = 1.89; 95%CI 1.32-2.68), the first appointment in public services (OR = 1.78; 95%CI 1.20-2.64), care in more than two health services in the clinical pathway (OR = 1.71; 95%CI 1.19-2.44); and obtaining the anatomopathological analysis of the biopsy in public services instead of private health services (OR = 1.87; 95%CI 1.29-2.71). Independently, the implementation of specialist appointment scheduling, with care regulation, was associated with a shorter time interval between first appointment and therapy (OR = 0.33; 95%CI 0.16-0.65). CONCLUSIONS: We observed that multiple pathways were covered by women with breast cancer treated in public services of the Federal District. Socioeconomic iniquities and several aspectos of the pathways covered were associated with a longer time interval between the first appointment and the start of breast cancer therapy.

RESUMO OBJETIVO: Conhecer os itinerários terapêuticos de mulheres com câncer de mama tratadas em hospitais públicos, assim como analisar os fatores que influenciam o intervalo de tempo entre a primeira consulta e o início do tratamento. MÉTODOS: Realizou-se um estudo transversal com 600 mulheres com câncer de mama tratadas em nove hospitais públicos do Distrito Federal, Brasil. As pacientes foram entrevistadas entre setembro de 2012 e setembro de 2014. Foram ajustados modelos de regressão logística simples e múltipla para avaliar as variáveis associadas ao intervalo de tempo estudado. O itinerário mais frequente foi aquele iniciado na atenção primária com atendimento subsequente no serviço de tratamento (28,9%). No ajuste múltiplo, foram associados a um maior tempo entre a primeira consulta e o tratamento: menor renda familiar (OR = 1,89; IC95% 1,32-2,68), realização da primeira consulta em serviços públicos (OR = 1,78; I IC95% 1,20-2,64), atendimento em mais de dois serviços de saúde no itinerário terapêutico (OR = 1,71; IC95% 1,19-2,44); e obtenção da análise anatomopatológica da biópsia em serviços públicos ao invés de serviços de saúde privados (OR = 1,87; IC95% 1,29-2,71). De forma independente, a implementação do agendamento de consulta com especialista, por meio da regulação assistencial, foi associada a um menor intervalo de tempo entre primeira consulta e tratamento (OR = 0,33; IC95% 0,16-0,65). CONCLUSÕES: Observou-se que múltiplos itinerários foram percorridos pelas mulheres com câncer de mama tratadas em serviços públicos do Distrito Federal. Iniquidades socioeconômicas e diversos aspectos dos itinerários percorridos foram associados a um maior intervalo de tempo entre a primeira consulta e início do tratamento do câncer de mama.

Wide Excision Using Indigo-Carmine to Minimize the Recurrence of a Pilonidal Cyst: Technical Note / 대한정형외과학회잡지

The cause of a pilonidal cyst is unclear, and treatment is still under debate. In Korea, the incidence of this disease is lower than that of Western countries, and it has often been misdiagnosed as a simple abscess. When pilonidal cysts are diagnosed, the principle of treatment is not to leave a residue, and a wide excision is needed to reduce the recurrence rate. This paper introduces a wide excision technique using Indigo-carmine dye to minimize the recurrence of a pilonidal cyst.

Conclusiones: con el elevado aporte del cáncer de pulmón a la morbilidad y mortalidad general en Cuba y en particular en la provincia de Camagüey, así como el consecuente impacto negativo en la duración y calidad de vida de la población, se considera pertinente y necesario el diseño de un programa integral asistencial organizacional para atender a pacientes con esta terrible y letal enfermedad.

ABSTRACT Background: cancer is one of the leading causes of death around the world. In 2012, there were 14 million of new cases, as well as 8.2 million related deaths. Within all cancer locations, the lung is the one with the highest incidence and mortality for men and in the case of women, it occupies the second place. Objectives: to carry out an update on epidemiological aspects of diagnosis, as well as the treatment of lung cancer at a global, regional and local level. Methods: a search on Pub Med, SciELO, Medline, Cochrane, Lilacs databases using EndNote and Clinical Key was carried out, from September 1 to December 15, 2017. The following keywords were used: lung cancer, epidemiology, diagnostic, treatment, screening. A bibliographic review of a total of 302 articles was made, of them 40 citations were used, most of them from the last three and five years. Original articles, full-text reviews, as well as opinion articles were considered for the review. Development: aspects of lung cancer, related to global, regional and local statistics, as well as impact indicators, aspects related to early diagnosis through screening and novel elements of clinical trials related to the application of the vaccine CIMAvax-EGF were addressed. Conclusions: with the high contribution of lung cancer to morbidity and general mortality in Cuba and in particular in Camagüey province, as well the negative consequent impact on the duration and quality of life of the population, it is considered necessary to design a comprehensive organizational assistance program to care for patients with this terrible and lethal disease.

Lung cancer in Brazil / Câncer de pulmão no Brasil

ABSTRACT Lung cancer is one of the most incident types of cancer and a leading cause of cancer mortality in Brazil. We reviewed the current status of lung cancer by searching relevant data on prevention, diagnosis, and treatment in the country. This review highlights several issues that need to be addressed, including smoking control, patient lack of awareness, late diagnosis, and disparities in the access to cancer health care facilities in Brazil. We propose strategies to help overcome these limitations and challenge health care providers, as well as the society and governmental representatives, to work together and to take a step forward in fighting lung cancer.

RESUMO O câncer de pulmão é um dos tipos de câncer com maior incidência e uma das principais causas de mortalidade por câncer no Brasil. Revisamos a situação atual do câncer de pulmão por meio de pesquisa de dados relevantes a respeito de prevenção, diagnóstico e tratamento no país. Esta revisão mostra várias questões que precisam de atenção, tais como controle do tabagismo, educação dos pacientes, desconhecimento por parte dos pacientes, diagnóstico tardio e desigualdade de acesso ao tratamento de câncer no Brasil. Propomos estratégias para ajudar a superar essas limitações e desafiamos os profissionais de saúde, a sociedade e os representantes do governo a trabalhar em conjunto e dar um passo à frente na luta contra o câncer de pulmão.

Anatomic pulmonary resection via video-assisted thoracic surgery: analysis of 117 cases at a referral center in Brazil / Ressecções pulmonares anatômicas por cirurgia torácica videoassistida: experiência de 117 casos em um centro de referência no Brasil

ABSTRACT Objective: To describe our experience with video-assisted thoracic surgery (VATS) for anatomic pulmonary resection at a referral center for thoracic surgery in Brazil. Methods: All patients who underwent anatomic pulmonary resection by VATS between 2010 and 2015 were included. Clinical and pathological data, as well as postoperative complications, were analyzed. Results: A total of 117 pulmonary resections by VATS were performed, of which 98 were lobectomies and 19 were anatomic segmentectomies. The mean age of the patients was 63.6 years (range, 15-86 years). Females predominated (n = 69; 59%). The mean time to chest tube removal was 2.47 days, and the mean length of ICU stay was 1.88 days. The mean length of hospital stay was 4.48 days. Bleeding ≥ 400 mL occurred in 15 patients. Conversion to thoracotomy was required in 4 patients. Conclusions: Our results are similar to those published in major international studies, indicating that VATS is an important strategy for pulmonary resection. They also show that VATS can be safely performed with adequate training. This technique should be used more often for the treatment of lung diseases in Brazil.

RESUMO Objetivo: Relatar a experiência com cirurgia torácica videoassistida (CTVA) para ressecções pulmonares anatômicas em um centro nacional de referência de cirurgia torácica no Brasil. Métodos: Foram incluídos todos os pacientes tratados com ressecções pulmonares anatômicas por CTVA entre 2010 e 2015 e analisados dados clínicos e patológicos, assim como complicações pós-operatórias. Resultados: Foram realizadas 117 ressecções pulmonares por CTVA, sendo 98 lobectomias e 19 segmentectomias anatômicas. A média de idade foi de 63,6 anos (variação, 15-86 anos), sendo a maioria mulheres (n = 69; 59%). A média de tempo de permanência com dreno foi de 2,47 dias e a de estada em UTI foi de 1,88 dias. A média de tempo de internação foi de 4,48 dias. Sangramento ≥ 400 ml ocorreu em 15 pacientes. Houve conversão para toracotomia em 4 pacientes. Conclusões: Nossos resultados vão ao encontro de publicações em grandes séries internacionais, corroborando que a CTVA é uma importante via de execução de ressecções pulmonares e que pode ser realizada com segurança quando há treinamento adequado, devendo ser mais utilizada no Brasil para o tratamento das doenças pulmonares.

Tuberculosis axillary lymph node coexistent breast cancer in adjuvant treatment: case report / Tuberculose linfonodal axilar coexistente com carcinoma mamário em tratamento adjuvante: relato de caso

Coexistence of breast cancer and tuberculosis is rare. In most cases, involvement by tuberculosis occurs in axillary lymph nodes. We report a case of a 43-years-old patient who had undergone adenomastectomy and left sentinel lymph node biopsy due to a triple negative ductal carcinoma. At the end of adjuvant treatment, the patient had an atypical lymph node in the left axilla. Lymph node was excised, and after laboratory analysis, the diagnosis was ganglion tuberculosis. The patient underwent treatment for primary tuberculosis. The development of these two pathologies can lead to problems in diagnosis and treatment. An accurate diagnosis is important to avoid unnecessary surgical procedures.

A coexistência de câncer de mama e tuberculose é rara. Na maioria das vezes, o acometimento pela tuberculose ocorre nos linfonodos axilares. Relatamos caso clínico de paciente de 43 anos submetida à adenomastectomia e à biópsia de linfonodo sentinela à esquerda devido a um carcinoma ductal triplo negativo. Ao final do tratamento adjuvante, a paciente apresentou linfonodomegalia atípica em axila esquerda. Foi realizado exérese do linfonodo e, após análises laboratoriais, diagnosticou-se tuberculose ganglionar. A paciente foi submetida a tratamento para tuberculose primária. O desenvolvimento dessas duas patologias pode acarretar problemas quanto ao diagnóstico e ao tratamento. O diagnóstico acurado é importante para evitar procedimentos cirúrgicos desnecessários.

Por que tratamos câncer de boca em estádios avançados? / Why do we treat mouth cancer in advanced stages?

No Brasil, registros hospitalares de câncer revelam a boca como a oitava localização mais frequente de tumores malignos, sendo a maioria delas diagnosticada em estádio avançado. Em países desenvolvidos, as taxas de diagnóstico tardio são cerca de 40%. O diagnóstico e tratamento precoces representam mais chance de cura, baixo custo emenos morbidade. Este artigo objetiva verificar as possíveis razões de atraso no diagnóstico e tratamento das neoplasias bucais e refletir sobre os seus motivos. Os termos neoplasias bucais, diagnóstico, epidemiologia e terapia foram introduzidos nas bases de dados MEDLINE, LILACS e SCIELO. Foram analisados 31 estudos, entre 1995 e 2011,que discorriam sobre o atraso diagnóstico em relação ao paciente, ao profissional e ao sistema de saúde. Observou-se que o atraso diagnóstico associou-se a: a) pacientes: solteiros, etilistas e com medo do diagnóstico; b) médico: pouco conhecimento sobre o assunto e alta carga de trabalho; c) sistema de saúde: filas para atendimento médico, distância de unidades de saúde e centros de referência da moradia do paciente e experiênciasnegativas no serviço de saúde. É fundamental entender as possíveis causas de atraso e limitações dos serviços de saúde e de seus profissionais para que medidas adequadas sejam tomadas individual e coletivamente para propiciar diagnóstico e tratamento precoce aos pacientes.

In Brazil, hospital cancer records reveal the mouth as the eighth most frequent location of malignant tumors, most of them being diagnosed at advanced stages. In developed countries, diagnosis of late rates is about 40%. Early diagnosis and treatment represent increased chances of a cure, low cost, and less morbidity. This article aims to assess thepossible reasons for delays in the diagnosis and treatment of oral cancer and reflects on the reasons. The terms mouth neoplasias, diagnosis, epidemiology, and therapy were introduced in the MEDLINE, LILACS, and SciELO databases. A total of 31 studies published between 1995 and 2011 were analyzed, which discoursed about the delayed diagnosis in relation to patients, professionals, and healthcare systems. It was observedthat the diagnostic delay was associated with: a) patients: single, alcoholic, and afraid of the diagnosis; b) Professionals: little knowledge on the subject and high workload; c) healthcare systems: queues for medical care, distance between the patient?s residence and healthcare units and reference centers, and negative experiences in the healthcareservice. It is critical to understand the possible causes of delay and limitations of healthcare services and its professionals for appropriate actions to take place individually and collectively providing early diagnosis and treatment to these patients.

Study on adherecce to capecitabine among patiens with colorectal cancer and meetastatic breast cancer / Estudo de aderência a capecitabina em pacientes com câncer colorretal e câncer de mama metastático

Context Capecitabine, an oral drug, is as effective as traditional chemotherapy drugs. Objectives To investigate the adhesion to treatment with oral capecitabine in breast and colorectal cancer, and to determine any correlation with changes in patient’s quality of life. Methods Patients with colorectal cancer or breast cancer using capecitabine were included. The patients were asked to bring any medication left at the time of scheduled visits. The QLQ-C30 questionnaire was applied at the first visit and 8-12 weeks after treatment. Results Thirty patients were evaluated. Adherence was 88.3% for metastatic colon cancer, 90.4% for non-metastatic colon cancer, 94.3% for rectal cancer and 96.2% for metastatic breast cancer. No strong correlation between adherence and European Organisation for Research and Treatment of Cancer QLQ-C30 functional or symptom scale rates had been found. There was no statistically significant correlation between compliance and the functional and symptom scales of the questionnaire before and after chemotherapy, with the exception of dyspnea. Conclusions Although no absolute adherence to oral capecitabine treatment had been observed, the level of adherence was good. Health professionals therefore need a greater focus in the monitoring the involvement of patients with oral treatment regimens. Patients with lesser degrees of dyspnea had greater compliance. .

Contexto A capecitabina, uma droga oral, é tão eficaz quanto as drogas quimioterápicas tradicionais. Objetivos Investigar a adesão ao tratamento oral com capecitabina para câncer de mama e colorretal e determinar qualquer correlação com as mudanças na qualidade de vida do paciente. Métodos Pacientes com câncer colorretal ou de mama em uso de capecitabina foram incluídos. A cada consulta os pacientes trouxeram a medicação restante. O questionário de qualidade de vida QLQ- C30 foi aplicado na primeira visita e 8-12 semanas após o tratamento. Resultados Trinta pacientes foram avaliados. A adesão foi de 88,3% para o câncer de cólon metastático, 90,4% para o de cólon não-metastático, 94,3% para o de reto e 96,2% para o de mama metastático. Com exceção da dispnéia, não houve forte correlação entre adesão e as taxas European Organisation for Research and Treatment of Cancer QLQ-C30 em relação a escala funcional ou de sintomas no início ou após quimioterapia. Conclusões O nível de adesão foi bom, embora não houvesse adesão absoluta ao tratamento com capecitabina oral. Os profissionais de saúde, portanto, precisam dar maior atenção a pacientes em regimes de tratamento oral. Os pacientes com menor grau de dispneia tiveram maior adesão. Neoplasias colorretais, terapia .
