ABSTRACT

OBJECTIVE:

To investigate the clinical application of CT and CT-guided percutaneous transthoracic needle biopsy (CT-PTNB) in patients with indeterminate pulmonary nodules (IPNs).

METHODS:

We retrospectively studied 113 patients with PNs undergoing CT and CT-PTNB. Variables such as gender, age at diagnosis, smoking status, CT findings, and CT-PTNB techniques were analyzed. Data analysis was performed with the Student's t-test for independent samples the chi-square test, and normal approximation test for comparison of two proportions.

RESULTS:

Of the 113 patients studied, 68 (60.2%) were male and 78 (69%) were smokers. The diameter of malignant lesions ranged from 2.6 cm to 10.0 cm. Most of the IPNs (85%) were located in the peripheral region. The biopsied IPNs were found to be malignant in 88 patients (77.8%) and benign in 25 (22.2%). Adenocarcinoma was the most common malignant tumor, affecting older patients. The IPN diameter was significantly greater in patients with malignant PNs than in those with benign IPNs (p < 0.001). Having regular contour correlated significantly with an IPN being benign (p = 0.022), whereas spiculated IPNs and bosselated IPNs were more often malignant (in 50.7% and 28.7%, respectively). Homogeneous attenuation and necrosis were more common in patients with malignant lesions (51.9% and 26.9%, respectively)

CONCLUSIONS:

In our sample, CT and CT-PTNB were useful in distinguishing between malignant and benign IPNs. Advanced age and smoking were significantly associated with malignancy. Certain CT findings related to IPNs (larger diameter, spiculated borders, homogeneous attenuation, and necrosis) were associated with malignancy. .
RESUMO

OBJETIVO:

Investigar a aplicação clínica da TC e da biópsia transtorácica percutânea guiada por TC (BTP-TC) em pacientes com nódulos pulmonares indeterminados (NPIs).

MÉTODOS:

Foram estudados retrospectivamente 113 pacientes portadores de NPIs submetidos a TC e BTP-TC. Foram analisadas variáveis como sexo, idade ao diagnóstico, tabagismo, achados tomográficos e técnicas de BTP-TC. A análise dos dados foi efetuada por meio do teste t de Student para amostras independentes, teste do qui-quadrado e teste de comparação de duas proporções por aproximação normal.

RESULTADOS:

Dos 113 pacientes estudados, 68 (60,2%) eram do sexo masculino e 78 (69%) eram tabagistas. O diâmetro das lesões malignas variou de 2,6 a 10,0 cm. A maioria dos NPIs estava localizada na região periférica (85%). O resultado da biópsia foi maligno em 88 pacientes (77,8%) e benigno em 25 (22,2%). O adenocarcinoma foi o tumor maligno mais frequente, acometendo pacientes com idade mais avançada. O diâmetro dos NPIs foi significativamente maior nos pacientes com malignidade (p < 0,001). Houve uma associação significativa entre NPIs com contorno regular e lesões benignas (p = 0,022), enquanto os de tipo espiculado e bocelado foram mais frequentes em pacientes com lesões malignas (50,7% e 28,7%, respectivamente). Atenuação homogênea e necrose foram mais frequentes em pacientes com lesões malignas (51,9% e 26,9%, respectivamente).

CONCLUSÕES:

A TC e a BTP-TC foram úteis no diagnóstico diferencial entre lesões malignas e benignas nos pacientes com NPIs nesta amostra. Idade mais avançada e tabagismo associaram-se significativamente com malignidade. Houve associações de achados tomográficos (diâmetro maior, contorno espiculado, atenuação homogênea ...
