RESUMO
BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

RESUMO
OBJECTIVE: To evaluate the prevalence of anorexia and weight loss at diagnosis (pre-treatment), to identify the factors associated with pre-treatment weight loss, and to determine the prognostic role of anorexia and weight loss in the overall survival of patients with stage IV lung cancer. METHODS: This was a retrospective observational cohort study. The patients were stratified by the presence/absence of anorexia and of pre-treatment weight loss, which generated a measure composed of four categories, which were the independent variables. RESULTS: Among the 552 patients included in the study, anorexia and pre-treatment weight loss were present in 39.1% and 70.1%, respectively. After adjusting for age, male gender, and Karnofsky performance status, we found that anorexia and tumor size were significantly associated with pre-treatment weight loss. In a Cox multivariate analysis, adjusted for age, male gender and low Karnofsky performance status were found to be independent predictors of worse survival, as was concomitance of anorexia and weight loss. CONCLUSIONS: Anorexia and pre-treatment weight loss appear to be relevant problems in the follow-up of patients with advanced (stage IV) lung cancer Specific interventions are of crucial importance in individualized treatment plans, even within the context of palliative care.

RESUMO Objetivo: Avaliar a prevalência de anorexia e perda de peso ao diagnóstico (pré-tratamento), os fatores associados à perda de peso pré-tratamento e o papel prognóstico da anorexia e da perda de peso na sobrevida global de pacientes com câncer de pulmão em estádio IV. Métodos: Estudo de coorte retrospectivo observacional. Os pacientes foram estratificados, dependendo da presença/ausência de anorexia e da presença/ausência de perda de peso pré-tratamento, o que gerou uma medida composta de anorexia e perda de peso de quatro níveis, que foi a variável independente. Resultados: Entre os 552 pacientes incluídos no estudo, as prevalências de anorexia e de perda de peso pré-tratamento foram de 39,1% e 70,1%, respectivamente. Após ajustar para idade, sexo masculino e índice de Karnofsky, a presença de anorexia e o tamanho do tumor foram significativamente associados à perda de peso pré-tratamento. Na análise multivariada de Cox, após ajustar para a idade, as variáveis sexo masculino, presença concomitante de anorexia e perda de peso e índice de Karnofsky reduzido foram preditores independentes de pior probabilidade de sobrevida. Conclusões: O presente estudo demonstrou que a presença de anorexia e de perda de peso pré-tratamento são problemas relevantes no seguimento de pacientes com câncer de pulmão avançado (estádio IV). Intervenções específicas são de crucial importância no plano de assistência individualizada, mesmo dentro da proposta de cuidados paliativos.

OBJECTIVE: To evaluate the diagnostic accuracy of CT-guided percutaneous core needle biopsy (CT-CNB) of pulmonary nodules ≤ 2 cm, as well as to identify factors influencing the accuracy of the procedure and its morbidity. METHODS: This was a retrospective, single-center study of 170 consecutive patients undergoing CT-CNB of small pulmonary nodules (of ≤ 2 cm) between January of 2010 and August of 2015. RESULTS: A total of 156 CT-CNBs yielded a definitive diagnosis, the overall diagnostic accuracy being 92.3%. Larger lesions were associated with a higher overall accuracy (OR = 1.30; p = 0.007). Parenchymal hemorrhage occurring during the procedure led to lower accuracy rates (OR = 0.13; p = 0.022). Pneumothorax was the most common complication. A pleura-to-lesion distance > 3 cm was identified as a risk factor for pneumothorax (OR = 16.94), whereas performing a blood patch after biopsy was a protective factor for pneumothorax (OR = 0.18). CONCLUSIONS: Small nodules (of < 2 cm) represent a technical challenge for diagnosis. CT-CNB is an excellent diagnostic tool, its accuracy being high.

RESUMO Objetivo: Avaliar a precisão diagnóstica da biópsia percutânea com agulha grossa, guiada por TC - doravante denominada BAG-TC - de nódulos pulmonares ≤ 2 cm, bem como identificar fatores que influenciam a precisão do procedimento e sua morbidade. Métodos: Estudo retrospectivo, realizado em um único centro, com 170 pacientes consecutivos submetidos a BAG-TC de nódulos pulmonares pequenos (≤ 2 cm) entre janeiro de 2010 e agosto de 2015. Resultados: Do total de biópsias, 156 resultaram em diagnóstico definitivo, com precisão diagnóstica global de 92,3%. Lesões maiores estiveram relacionadas com maior precisão global (OR = 1,30; p = 0,007). A presença de hemorragia parenquimatosa durante o procedimento resultou em menor precisão (OR = 0,13; p = 0,022). Pneumotórax foi a complicação mais comum. Uma distância > 3 cm entre a lesão e a pleura foi identificada como fator de risco de pneumotórax (OR = 16,94), ao passo que a realização de tampão sanguíneo após a biópsia foi um fator de proteção contra o pneumotórax (OR = 0,18). Conclusões: O diagnóstico de nódulos pequenos (< 2 cm) é um desafio do ponto de vista técnico. A BAG-TC é uma excelente ferramenta diagnóstica, cuja precisão é alta.

OBJECTIVE: To describe the results of endobronchial ultrasound-guided transbronchial needle aspiration in making diagnosis of mediastinal injuries associated to different causes. METHODS: A retrospective cross-sectional study of patients submitted to Endobronchial ultrasound-guided transbronchial needle aspiration at a private organization, between June 2013 and October 2016. All cases referred for collection of lymph nodes or peritracheal/peribronchial masses by endobronchial ultrasound-guided transbronchial needle aspiration, and evaluated through tomography or PET-CT were included. Interventional pulmonologists and thoracic surgeons with experience in the method did the procedures. Rapid on-site evaluation of fine needle aspiration was performed by an experienced pathologist. Material analysis included cytological smear and cytopathological analysis of paraffin-embedded cell blocks. Other specific analyses (immunocytochemistry, tests and cultures of infectious agents) were performed whenever necessary. RESULTS: We included 72 patients; 6 were excluded for presenting endobronchial lesions in which bronchoscopic biopsy could be performed, or intrathoracic lesions that were not accessible by endobronchial ultrasound-guided transbronchial needle aspiration. The mean age of 66 patients included for analysis was 61.17 years (±14.67 years), with a predominance of males (64%). Endobronchial ultrasound-guided transbronchial needle aspiration was definitive for diagnosis in 60 cases (91%). Three cases (4.5%) had inconclusive test results. There were no major complications related to the procedure. CONCLUSION: Endobronchial ultrasound-guided transbronchial needle aspiration had a high diagnosis yield, with minimal morbidity, being an excellent option for diagnostic approach of patients with lymphadenopathy or intrathoracic lesions, and for neoplasm staging.

RESUMO Objetivo Descrever os resultados da utilização de punção aspirativa por agulha guiada por ultrassom endobrônquico na definição do diagnóstico em casos de lesões mediastinais por diferentes causas. Métodos Estudo transversal retrospectivo de pacientes submetidos à punção aspirativa por agulha guiada por ultrassom endobrônquico em instituição privada, entre junho de 2013 e outubro de 2016. Foram incluídos todos os casos referenciados para coleta de materiais de linfonodos ou massas peritraqueais/peribrônquicas por punção aspirativa por agulha guiada por ultrassom endobrônquico, estudados com tomografia ou PET-CT. Os procedimentos foram realizados por pneumologistas intervencionistas e cirurgiões torácicos com experiência no método. Rapid on-site evaluation da punção aspirativa por agulha fina foi realizada por patologista experiente. A análise do material incluiu citologia dos esfregaços em lâminas e análise citopatológica do emblocado celular. Outras análises específicas (imunocitoquímica, pesquisas e culturas de agentes infecciosos) foram realizadas se necessárias. Resultados Foram incluídos 72 pacientes; destes, 6 foram excluídos por apresentarem lesões endobrônquicas passíveis de biópsia broncoscópica convencional ou lesões intratorácicas não acessíveis a punção aspirativa por agulha guiada por ultrassom endobrônquico. Assim, a média de idade dos 66 pacientes incluídos para análise foi 61,17 anos (±14,67 anos), com predomínio do sexo masculino (64%). A punção aspirativa por agulha guiada por ultrassom endobrônquico foi definitivo para o diagnóstico em 60 casos (91%). Três casos (4,5%) foram inconclusivos. Não houve complicações maiores relacionadas ao procedimento. Conclusão A punção aspirativa por agulha guiada por ultrassom endobrônquico teve elevado rendimento diagnóstico, com mínima morbidade, constituindo excelente opção na abordagem diagnóstica de pacientes com linfadenopatia ou lesões intratorácicas e no estadiamento de neoplasias.
