RESUMO Objetivo. Investigar a carga de câncer de traqueia, brônquios e pulmão (TBP) decorrente da exposição ao tabaco nos últimos 30 anos em 12 países da América do Sul. Métodos. A função de exposição-resposta do estudo Carga Global de Doença (GBD, na sigla em inglês) 2019 foi usada para analisar o número de mortes e de anos de vida ajustados por incapacidade (AVAI) por câncer de TBP relacionado à exposição total ao tabaco e ao tabagismo e ao fumo passivo em 12 países da América do Sul entre 1990 e 2019. Os índices foram descritos em números absolutos ou taxas por 100 mil pessoas. A variação relativa da carga foi avaliada comparando-se os períodos de 1990 a 1994 e de 2015 a 2019. Resultados. Em 2019, os números de mortes e de AVAI por câncer de TBP associado à exposição ao tabaco na América do Sul, em todas as idades, foram, respectivamente, 29.348 e 658.204 em homens e 14.106 e 318.277 em mulheres. As taxas de mortalidade e os AVAI ajustados por idade na região foram, respectivamente, 182,8 e 4.035 em homens e 50,8 e 1.162 em mulheres em 2019. Em homens, 10 dos 12 países registraram uma diminuição relativa das taxas de mortalidade por câncer de TBP atribuído à exposição ao tabaco, mas somente 4 países obtiveram uma redução da mortalidade em mulheres. Conclusão. Apesar dos consideráveis esforços atuais para o controle do tabaco na América do Sul, ainda há uma expressiva carga de câncer de TBP na região, com disparidades significativas entre os sexos. É necessário dispor de mais dados primários sobre câncer de TBP e exposição ao tabaco específicos para cada país para aprimorar as estratégias de atenção à saúde e melhorar a compreensão das tendências regionais.

RESUMEN Objetivo. Investigar la carga del cáncer de tráquea, bronquios y pulmón por exposición al tabaco en los últimos 30 años en 12 países de Sudamérica. Métodos. Se utilizó la función de relación entre exposición y respuesta de la carga mundial de morbilidad del 2019 para analizar las muertes por cáncer de tráquea, bronquios y pulmón asociadas a la exposición total al tabaco, al tabaquismo activo y al tabaquismo pasivo, así como los años de vida ajustados en función de la discapacidad (AVAD), en 12 países de Sudamérica, entre 1990 y el 2019. Los resultados se presentaron en forma de número absoluto o de tasa por 100 000 personas. Se evaluó el cambio relativo de la carga mediante la comparación de los períodos 1990-1994 y 2015-2019. Resultados. En el 2019, el número de muertes por cáncer de tráquea, bronquios y pulmón y los AVAD asociados a la exposición al tabaco para todas las edades en Sudamérica fueron de 29 348 y 658 204 en los hombres y de 14 106 y 318 277 en las mujeres, respectivamente. La tasa de mortalidad y los AVAD ajustados por la edad correspondientes al 2019 en la región fueron de 182,8 y 4035 en los hombres y de 50,8 y 1162 en las mujeres, respectivamente. En el caso de los hombres, en 10 de los 12 países se observaron disminuciones relativas de la tasa de mortalidad por cáncer de tráquea, bronquios y pulmón atribuido a la exposición al tabaco, mientras que en el caso de las mujeres solo en 4 países hubo una reducción de la mortalidad. Conclusión. Aunque en Sudamérica se están llevando a cabo iniciativas importantes para el control del tabaco, en esta región persiste una carga considerable de cáncer de tráquea, bronquios y pulmón, con diferencias significativas en función del sexo. Es preciso contar con más datos primarios específicos de cada país sobre el cáncer de tráquea, bronquios y pulmón, así como sobre la exposición al tabaco, para optimizar las estrategias de atención de salud y mejorar la comprensión de las tendencias regionales.

ABSTRACT Objective. To investigate the burden of tracheal, bronchus, and lung (TBL) cancer due to tobacco exposure in the last 30 years in 12 South American countries. Methods. We used the Global Burden of Disease (GBD) 2019 exposure-response function to analyze the total tobacco, smoking, and secondhand smoke exposure-related TBL cancer deaths and disability-adjusted life years (DALYs), for 12 South American countries, between 1990 and 2019. Metrics were described as absolute numbers or rates per 100 000 individuals. The relative change in burden was assessed by comparing the 1990-1994 to 2015-2019 periods. Results. In 2019, the all-ages number of TBL cancer deaths and DALYs associated with tobacco exposure in South America was 29 348 and 658 204 in males and 14 106 and 318 277 in females, respectively. Age-adjusted death and DALYs rates for the region in 2019 were 182.8 and 4035 in males and 50.8 and 1162 in females, respectively. In males, 10/12 countries observed relative declines in TBL death rates attributed to tobacco exposure while only 4 countries reduced their mortality in females. Conclusion. While significant efforts on tobacco control are under place in South America, substantial burden of TBL cancer persists in the region with significant sex-specific disparities. Increased country-specific primary data on TBL cancer and tobacco exposure is needed to optimize healthcare strategies and improve comprehension of regional trends.

Abstract Introduction Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates. Methods Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022. Treatment outcomes and overall survival were analyzed with the Kaplan-Meier method. Results Thirty-seven male patients were included with a median age of 31.8 years. Six presented with synchronous mediastinum and lung metastasis, nine had only lung, and 22 had mediastinal metastasis. Over half had retroperitoneal lymph node metastasis. Twenty-two had dissimilar pathologies, with a discordance rate of 62 %. Teratoma and embryonal carcinoma were the prevalent primary tumor types, 40.5 % each, while teratoma was predominant (70.3 %) in the metastasis group. Thoracotomy was the main surgical approach (39.2 %) followed by VATS (37.2 %), cervico-sternotomy (9.8 %), sternotomy (5.8 %), and clamshell (3.9 %). Lung resection was performed in 40.5 % of cases. Overall, 10-year survival rates were 94.3 % with no surgical-related mortality. Conclusion Multimodality treatment with systemic therapy followed by radical surgery offers a high cure rate to patients with intrathoracic metastatic testicular germ cell tumors. 2 NonSeminomatous Non Seminomatous (NSGCT chemotherapy longterm long term 201 2022 KaplanMeier Kaplan Meier method Thirtyseven Thirty seven 318 31 8 31. years Twentytwo Twenty two pathologies 6 types 405 40 5 40. each 70.3 703 70 3 (70. group 39.2 392 39 (39. 37.2 372 37 (37. %, , cervicosternotomy cervico 9.8 98 9 (9. 5.8 58 (5. 3.9 (3. . cases Overall 10year year 10 943 94 94. surgicalrelated related mortality tumors 202 4 70. 7 (70 39.

Abstract Introduction: Aortic diseases are among the most serious cardiovascular diseases; the overall mortality rate due to diseases such as aneurysms and aortic dissections has been estimated at 2.78 per 100,000 persons in 2010, with a higher mortality rate in men than women. Our objective was to evaluate the epidemiological profile of patients with acute type A aortic dissection at a cardiology referral center. Methods: A retrospective cross-sectional study was performed at a public cardiac center with 24 patients hospitalized from 1/1/2016 to 12/31/2017 with a confirmed diagnosis of acute type A aortic dissection. Results: Twenty (83.3%) out of 24 patients underwent surgery and four (16.7%) did not undergo surgery. Among those who underwent surgery, 10 (50%) died and 10 (50%) were discharged, and all non-operated patients died (P=0.114) (Fisher's exact test). The male gender predominated (n=19, 79.2%), 86.7% (n=13) of the patients presented body mass index > 25 kg/m2, chest pain was found in 91.7% (n=22), and renal failure was present in 45.8% (n=11) of the cases. Hypertension predominated in 91.7% (n=22) and the main exam was aortic angiotomography in 79.2% (n=19) of the cases. Conclusion: The study presented a small sample size, making it impossible to associate the factors, although the service was considered a high-volume referral center. It is possible that the delay in arriving at the service and the accomplishment of invasive imaging with the use of contrast agents have aggravated the patients’ condition and have been decisive for the increase in lethality, which requires further studies.
