ABSTRACT
El cáncer pulmonar se establece como la segunda causa de muerte en países desarrollados y en algunos en vías de desarrollo. Su diagnóstico es tardío, sus opciones de resección y su curación aun con terapias adyuvantes son limitadas, lo que incide en la pobre sobrevida a 5 años, es por ello que se necesitan mayores esfuerzos para combatir el hábito del tabaco, principal agente etiológico. Material y Métodos: Se trata de un estudio descriptivo transversal en pacientes adultos atendidos de 01 de enero del 2011 al 31 de diciembre del 2021, ingresados al servicio de cirugía del Hospital San Vicente de Guatemala, con diagnósticos de cáncer pulmonar, masa pulmonar, derrame pleural o nódulo pulmonar solitario. Resultados: Se atendieron 202 pacientes con diagnósticos presuntivos de cáncer pulmonar, no encontrando diferencias significativas en relación al sexo. La edad mayormente afectada se estableció entre los 50 y 70 años. Prevalecieron los estadíos IIIA, IIIB y IV basados en los hallazgos clínicos, tomográficos y transoperatorios y solo al 10% se le sometió a una cirugía de resección pulmonar mayor. Los cánceres de células no pequeñas NSCLC fueron reportados en el 68.7% y el adenocarcinoma fue la variedad más frecuente con el 54.95% sobre el 7.29% del epidermoide. La mortalidad a los treinta días se estableció en 2.97%. Conclusión: El adenocarcinoma pulmonar ocupa el primer lugar en la incidencia de los cánceres pulmonares, desplazando así al carcinoma epidermoide popularizado desde la mitad del siglo pasado. Esta tendencia en el cambio histológico está firmemente asociado a las modificaciones en los hábitos del fumar (AU)
Lung cancer is established as the second cause of death in developed countries and in some developing ones. Its diagnosis is late, its resection options and its cure even with adjuvant therapies are limited, which affects the poor survival at 5 years, which is why greater efforts are needed to combat the tobacco habit, the main etiological agent. Material and Methods: This is a cross-sectional descriptive study in adult patients treated from January 1, 2011 to December 31, 2021, admitted to the surgery service of the Hospital San Vicente de Guatemala, with diagnoses of lung cancer, lung mass, effusion pleural or solitary pulmonary nodule. Results: 202 patients with presumptive diagnoses of lung cancer were treated, finding no significant differences in relation to sex and the most affected age was established between 50 and 70 years. Stages IIIA, IIIB, and IV prevailed based on clinical, tomographic, and intraoperative findings, and only 10% underwent major lung resection surgery. NSCLC non-small cell cancers were reported in 68.7% and adenocarcinoma was the most frequent variety with 54.95% over 7.29% of epidermoid. Thirty-day mortality was established at 2.97%. Conclusion: Pulmonary adenocarcinoma occupies the first place in the incidence of lung cancers, thus displacing squamous cell carcinoma popularized since the middle of the last century. This trend in histological change is strongly associated with changes in smoking habits.

Background: Pulmonary nodules are common, and surgery is the only alternative that allows a diagnostic and therapeutic management in a single procedure. Aim: To report the epidemiological, radiological, surgical and pathological features of excised pulmonary nodules. Material and Methods: Review of medical records of patients in whom a pulmonary nodule was excised between 2014 and 2018. Those with incomplete data or without a pathological study were excluded from analysis. Results: We retrieved 108 records and 8 had to be excluded, therefore 100 patients aged 34 to 82 years (57% females) were analyzed. Sixty percent had a history of smoking. Mean nodule size was 16 mm and the solid type was the most common (65%). Forty five percent of nodules had irregular margins and 55% were in the superior lobes. All patients operated by video-assisted thoracoscopic surgery and 40% underwent a lobectomy. Malignant lesions were observed in 87% of biopsies and a pulmonary adenocarcinoma was found in pathology in 40%. Conclusions: A multidisciplinary approach of pulmonary nodules, using adapted international guidelines, accomplishes an appropriate management, decreasing unnecessary surgical interventions.
