Objective: To analyze the locations of lung carcinomas in relation to patient gender and smoking status. Methods: In order to test the hypothesis that lung carcinoma location (upper or lower lobe; left or right side) is correlated with smoking status and gender, we conducted a retrospective study of 697 patients with bronchogenic carcinoma treated at the Pulmonology-Oncology Outpatient Clinic of the Federal University of São Paulo. Results: We found that the bronchogenic carcinomas occurring in smokers were more frequently located in the upper lobes, whereas those occurring in nonsmokers were more frequently located in the lower lobes. In women, the neoplasms were more often seen in the lower lobes, especially in nonsmokers. Based on the available data, there were no differences in terms of the side affected (left or right). Conclusion: Overall, bronchogenic carcinomas are predominantly found in the upper lobes. However, in nonsmokers, they occur more frequently in the lower lobes. In females, bronchogenic carcinomas present a tendency to occur more often in the lower lobes.
Objetivo: verificar as diferenças dos fatores prognósticos de dois grupos distintos de portadores de carcinoma não pequenas células de pulmão: sobrevida superior a cinco anos e sobrevida inferior ou igual a um ano. Métodos: vinte e oito pacientes com maior sobrevida e 182 pacientes com menor sobrevida avaliados dos prontuários do ambulatório de Onco-Pneumologia da Unifesp. Foram avaliados dados clínicos, hábito tabágico, peso, estádio, tratamento e laboratoriais (CEA e DHL). Resultados: os fatores que influenciaram a sobrevida foram a capacidade funcional, doença localizada, perda de peso, DHL, CEA e a cirurgia. Conclusão: a avaliação destes fatores permite a escolha do melhor tratamento para cada paciente.
