“…No distant metastases M1 Distant metastases present one-half of the TNM stages derived from CT agree with operative staging, with patients being both under and over staged [91,92]. However, quick access to investigation, high histological confirmation rates (at bronchoscopic/transthoracic biopsy or at thoracotomy), routine CT scanning and review of every patient by a thoracic surgeon is known to substantially increase successful surgical resection [93].…”

Carcinoma of the bronchus is the most common malignancy in the Western world. It is also the leading cause of cancer-related death accounting for 32% of all cancer deaths in males and 25% in females [1]. In the USA it causes more deaths than cancers of the colon, breast and prostate combined [2]. Disappointingly, in a recent UK survey of improvements in cancer survival [3], carcinoma of the bronchus showed the smallest percentage reduction in the number of deaths avoided between 1981-1990 (0.2%). This compares badly with breast (11% reduction) and melanoma (32%). The overall 5-yr survival for lung cancer diagnosed between 1986-1990 was only 5.3% (against 66% for breast and 76% for melanoma). It is on this background that the radiologist remains actively employed in the detection, diagnosis, staging and review of this common malignancy.

“…PRIMACK et al [12] found that in a series of 275 patients, 24% of patients with CT findings suggesting bronchogenic carcinoma had unequivocal evidence that the tumour was unresectable. However, very often CT scanning disagrees with the tumour stage found at surgery [13][14][15]. Even though CT can provide important information as to whether or not the tumour has invaded the central vessels, the bronchial tree or the chest wall or has crossed the fissure, in many cases the surgeon still makes a final decision based on the findings at bronchoscopy and thoracotomy [16,17].…”

Computed tomography (CT) provides the most detailed imaging information, hence it is generally used as a routine imaging procedure in the tumour, node, metastasis (TNM)-staging of patients with lung cancer. However, despite the continuously ongoing process of improvement in CT scanning in which today9s CT scanners combine fast acquisition, fast data reconstruction and high detail, the technique has important limitations.CT can, in some cases, very accurately show tumour extent within, and predict spread beyond the lung. However, the question of whether the tumour has invaded the chest wall or the mediastinum and, if so, whether it is still potentially surgically curable often remains unanswered. In addition, the only sign for predicting lymph node involvement using CT is enlargement. Many studies have shown that this sign is not very reliable. CT is also, with success, being used to evaluate distant metastases although other techniques such as ultrasound and magnetic resonance imaging can have similar or higher accuracies.Despite these well-known limitations, computed tomography will most likely stay the routine imaging procedure for determining resectability and for assessing intra-and extrathoracic spread of lung cancer. The improvement in technology will probably result a better T-staging. The role of computed tomography in nodal staging remains important. It offers the surgeon a road map of the lymph nodes and guides towards the nodes that need biopsy. Combining computed tomography with positron emission tomography, when it becomes more widely available, will add functional images to the detail of computed tomography and will not only improve nodal staging but will probably also allow a better evaluation of distant metastasis and reduce the number of unnecessary interventional procedures.

A avaliação do paciente com câncer de pulmão envolve a detecção de aumento linfonodal mediastinal, invasão das estruturas mediastinais e também a determinação de metástases extratorácicas. Este artigo revisa a maioria das técnicas de imagem mais utilizadas no processo de estadiamento do câncer pulmonar broncogênico. O estudo radiológico do nódulo pulmonar solitário tem tido grande impacto.Estadiamento mediastinal com os métodos de imagem correntes é impreciso. TC e RM do tórax e abdome superior são freqüentemente usados para estadiar o câncer pulmonar presumido ou conhecido. A despeito de suas limitações, os estudos de imagem podem prevenir toracotomias ou procedimentos invasivos desnecessários na presença de achados inequívocos de doença avançada. RM pode ser útil na avaliação de regiões do tórax que são maldemonstradas nas imagens axiais de TC. PET-FDG é um método complementar ao TC na avaliação do paciente com câncer de pulmão, porém estratégias para o seu uso merecem futuras investigações. Pneumol 2002;28(2):94-99) Lung cancer radiology conjunto estão presentes o estudo radiológico convencional, tomografia linear, tomografia computadorizada (TC) e ressonância magnética (RM). A radiografia simples de tórax é o método inicial na avaliação do paciente com câncer pulmonar presumido ou conhecido. A tomografia computadorizada tornou-se a principal técnica de imagem para a avaliação desses pacientes devido às inúme-ras vantagens em relação aos métodos convencionais, principalmente com os recentes avanços dos equipamentos helicoidais single ou multi-slice.
