“…In addition, it explains the reduced number of patients submitted to surgical treatment, which is indisputably indicated in the early stages and is indicated with restrictions in the more advances stages. (8,9) In the literature, only approximately 20% of the cases meet the operability criteria at the time of diagnosis, even in developed countries. In developing countries, this rate would be expected to be lower due to the fact that the underprivileged population has limited access to health care.…”

Of the various histological types, the most common was squamous cell carcinoma and the least common was large cell carcinoma. Most cases presented advanced stages at the moment of diagnosis, and less than 30% of the cases presented early stages. This accounts for the low survival rate and the small number of patients submitted to surgical treatment alone, the majority being submitted to chemotherapy alone.

“…The current system was published in 1997 after a multicenter study involving more than 5,000 cases of lung cancer. (7,8) The treatment for lung cancer, when the tumor is still localized, without dissemination outside the lungs, is surgery. Tumors restricted to the lungs, in stages I and II, should be removed surgically.…”

“…The least common histological type was large cell carcinoma, a finding that is consistent with the literature. (3,4,9,11,12) One group of authors reported an increase in adenocarcinoma incidence, which can be higher than the incidence of squamous carcinoma. (18) According to Shields, (19) 30-50% are adenocarcinomas, 20-35% are squamous carcinomas, and 15-35% are small cell carcinomas.…”

“…Fiberoptic bronchoscopy is currently considered the primary method for evaluating the tracheobronchial tree in patients with suspected lung cancer. (4) In addition to allowing visualization of the lesion, the method allows the collection of cytological specimens (by bronchial lavage and bronchial brushing) and histological specimens (by endobronchial biopsy and transbronchial biopsy).…”

Objective: To compile fiberoptic bronchoscopy findings in patients diagnosed with lung cancer and to correlate those with histopathological findings. Methods: This was a retrospective study involving 212 patients with a confirmed diagnosis of lung cancer by cytological evaluation of BAL specimens or by histopathological evaluation of endobronchial or transbronchial biopsy specimens. The data were collected at the Respiratory Endoscopy Section of Hospital São Salvador, located in the city of Goiânia, Brazil, between 2005 and2010. The endoscopic findings were classified as endoscopically visible tumor, endoscopically invisible tumor, and mucosal injury, as well as being classified by the presence/type of secretion. The visible tumors were also classified according to their location in the tracheobronchial tree. Results: Endobronchial mass (64%) and mucosal infiltration (35%) were the main endoscopic findings. The histological type was determined in 199 cases, the most prevalent types being squamous carcinoma, in 78 (39%), adenocarcinoma, in 42 (21%), small cell carcinoma, in 24 (12%), and large cell carcinoma, in 2 (1%). More than 45% of the visible tumors were at the upper bronchi. Squamous carcinoma (n = 78) was most commonly visualized as an endobronchial mass (in 74%), mucosal infiltration (in 36%), luminal narrowing (in 10%), or external compression (in 6%). Conclusions: Our results show that an endobronchial mass is the most common bronchoscopic finding that is suggestive of malignancy. Proportionally, mucosal infiltration is the most common finding in small cell carcinoma. In adenocarcinoma, luminal narrowing, external compression, mucosal injury, and endobronchial secretion prevail.Keywords: Lung neoplasms/diagnosis; Lung neoplasms/classification; Bronchoscopy. ResumoObjetivo: Catalogar alterações encontradas em imagens obtidas por fibrobroncoscopia em pacientes com diagnóstico de neoplasia pulmonar e correlacionar esses achados com achados histopatológicos. Métodos: Estudo retrospectivo envolvendo 212 pacientes com diagnóstico de câncer de pulmão confirmado por citologia obtida por lavado broncoalveolar e/ou histopatologia de biópsia endobrônquica ou transbrônquica. Os dados foram obtidos no Serviço de Endoscopia Respiratória do Hospital São Salvador (Goiânia-GO), entre 2005 e 2010. Os achados endoscópicos foram classificados como tumor endoscopicamente visível, tumor endoscopicamente não visível e lesão na mucosa, assim com quanto à presença/tipo de secreção. Os tumores visíveis também foram classificados de acordo com sua localização na árvore traqueobrônquica. Resultados: O principal achado endoscópico foi a presença de massa endobrônquica (64%), seguido por infiltração da mucosa (35%). Quanto aos tipos histológicos (n = 199), os mais prevalentes foram carcinoma escamoso (39%), adenocarcinoma (21%), carcinoma de pequenas células (12%) e carcinoma de grandes células (1%). Mais de 45% dos tumores visíveis estavam localizados nos brônquios superiores. O carcinoma escamoso (n = 78) apresentou-se ma...

Revisão do sistema de estadiamento tumor-nódulo-metástase para câncer de pulmão: mudanças e perspectivas

The tumor-node-metastasis (TNM) staging system for lung cancer has been modified since its first edition in the late 1960s. Its seventh edition has been recently published and, for the first time, a truly worldwide database was analyzed in order to propose modifications in the staging. Significant changes have been made in the tumor and metastasis descriptors. Although the recommendations for the node descriptor have remained unchanged, the analysis of the factors related to this descriptor suggests that modifications will be made in the future. The forthcoming revisions of the TNM staging system might take the molecular aspects of lung cancer into consideration, aiming at a more refined staging system. Keywords: Lung neoplasms; Neoplasm staging; Epidemiologic methods. ResumoO sistema de estadiamento tumor-nódulo-metastase (TNM) para câncer de pulmão tem sido modificado desde sua primeira edição no final da década de 1960. Recentemente foi publicada sua sétima edição e, pela primeira vez, um banco de dados verdadeiramente mundial foi analisado para se propor modificações no estadiamento. Alterações significativas foram feitas nos descritores tumor e metástase. Embora as recomendações para o descritor nódulo permaneceram inalteradas, as análises dos fatores relacionados a esse descritor sugerem que modificações serão realizadas no futuro. As próximas revisões do sistema de estadiamento TNM podem levar em consideração aspectos moleculares do câncer de pulmão, objetivando um sistema de estadiamento mais refinado.Descritores: Neoplasias pulmonares; Estadiamento de neoplasias; Métodos epidemiológicos.* Study carried out in the
