“…Chest computed tomography (CT) plays a relevant role in the determination of presence and extent of lung cancer, demonstrating the size and site of the tumor. However, this method presents some limitations such as high cost, utilization of ionizing radiation, contrast agent nephrotoxicity, besides the necessity of further procedures to confirm the diagnosis (2,11) .…”

OBJETIVO: Analisar a tomografia computadorizada e a broncoscopia no diagnóstico do câncer pulmonar e verificar a eficácia destas técnicas perante a presença desta doença. Os parâmetros idade, gênero, hábitos tabágicos, tipos histológicos, estadiamento e terapêutica foram, igualmente, analisados. MATERIAIS E MÉTODOS: Foram analisados 70 pacientes do Serviço de Pneumologia do Hospital Distrital da Figueira da Foz, Coimbra, Portugal, que realizaram ambas as técnicas em estudo, tendo-se confirmado ou não a presença de câncer pulmonar. RESULTADOS: Diagnosticaram-se 37 tumores pulmonares, 23 casos no gênero masculino e 14 no feminino. Histologicamente, 40,54% eram adenocarcinomas, seguido do carcinoma escamoso (32,43% dos casos) e do carcinoma de pequenas células (18,92%). O estadiamento mostrou 6,70% no estádio IB, 23,30% no estádio IIIA comparativamente ao IIIB com 36,70%, encontrando-se 33,30% dos doentes no estádio IV. A quimioterapia isolada foi efetuada em 75,7% dos doentes. A sensibilidade da broncoscopia foi de 83,8%, a especificidade, de 81,8%, e a precisão, de 82,8%. A sensibilidade da tomografia computadorizada foi de 81,1%, a especificidade, de 63,6%, e a precisão, de 72,8%. CONCLUSÃO: Os resultados da broncoscopia confirmaram a sua importância no diagnóstico do câncer pulmonar, pela dependência deste no exame anatomopatológico do tecido ou células, obtido por várias técnicas de biópsia. A tomografia computadorizada apresentou boa sensibilidade, de 81,1%, contudo, a sua especificidade, de apenas 63,6%, resulta do número de falso-positivos (36,4%).

“…The staging is aimed at dividing cancer patients into subgroups to define their prognosis and to determine the therapeutic options. It is important to note that imaging methods play an essential role in the staging and follow-up of patients with lung cancer (2,11,18) .…”

Lung cancer is the leading cause of cancer death in both men and women and is the second most common type in both. It generally has a poor prognosis, with 75 percent of patients being diagnosed at an advanced stage. The diagnostic tools typically in use are insufficiently sensitive and do not allow for early disease detection. As a result, finding alternative ways of early and accurate lung cancer diagnosis is critical for successful management. CT imaging, sputum cytology, biopsy, and bronchoscopy are examples of traditional procedures that have been adjusted over time to improve sensitivity and accuracy. Lung biopsy is a reliable procedure performed to help define the treatment strategy for patients with lung cancer. The use of computed tomography (CT), EBUS, EUS and bronchoscopy allowed the collection of specimens for a greater number of patients through minimally invasive procedures. The recent advances in molecular technologies and analytic platforms have made it possible to investigate the gene variations that contribute to tumorigenesis and become potential lung cancer biomarkers. Furthermore, liquid biopsies tend to be a safe alternative to traditional biopsies and can offer both accurate molecular data and a less invasive method of evaluating tumor activity, which could further improve the clinical management of lung cancer patients. This chapter provides an overview of the different traditional and emerging diagnostic tools for lung cancer. We need to understand the characteristics of these procedures that could have predictive, prognostic and therapeutic implications.
