ABSTRACT
Introducción y objetivos: Al mejorar la supervivencia del cáncer, la presencia de tumores múltiples en un paciente es cada vez más frecuente. El objetivo del estudio ha sido analizar la evolución a largo plazo, especialmente las posibles recidivas y segundos tumores primarios, en pacientes con cáncer de pulmón (CP) y supervivencia ≥ 3 años. Material y métodos: Estudio retrospectivo de 1.769 pacientes con CP. Se incluyen 218 (136 tratados con cirugía y 82 con otros tratamientos) con supervivencia global ≥ 3 años, de cualquier estirpe y seguidos durante un período entre 5 y 23 años. Se registró la evolución del CP y las enfermedades intercurrentes. Resultados: Un total de 65 presentaron recidiva del tumor, de los cuales el 60,9% apareció en los 3 primeros años; 26 desarrollaron segundos primarios pulmonares (84,6% después de 5 años) y 24, 2 o más segundos extrapulmonares (66,6% después de 5 años), la mayoría relacionados con el tabaco. La incidencia de segundos primarios fue superior a la incidencia esperable de cáncer en población general de similar edad y género. Conclusión: El efecto carcinogénico múltiple del tabaco persiste y se manifiesta en diversos órganos después de pasados 5 años tras el diagnóstico de CP, incluso en pacientes que han tenido una larga supervivencia. Después de 5 años, un segundo tumor es más probable que una recidiva del primero y el pulmón es el órgano con mayor probabilidad de desarrollar un segundo tumor
Introduction and objectives: As cancer survival improves, the appearance of multiple tumors in a single patient is becoming more common. The aim of this study was to analyze long-term evolution, focusing particularly on disease recurrence and second primary tumors, in patients with lung cancer (LC) and ≥ 3 years overall survival. Material and methods: Retrospective study of 1,769 patients with LC. A total of 218 (136 treated with surgery and 82 with other treatments), followed up for between 5 and 23 years were enrolled. LC progress and intercurrent diseases were recorded. Results: A total of 65 patients presented tumor relapse, of which 60.9% occurred in the first 3 years; 26 patients developed secondary primary tumors (84.6% after 5 years) and 24 developed 2 or more second extrapulmonary tumors (66.6% after 5 years), most of which were smoking-related. The incidence of second primaries was greater than the expected incidence of cancer in the general population matched for age and sex. Conclusion: The multiple carcinogenic effect of smoking persists and manifests in various organs, more than 5 years after the diagnosis of LC, even in patients with long survival. After 5 years, a second tumor is more likely than a relapse of the primary disease, and the lung is the most common site of development of a second tumor
