Diagnostic imaging and staging of primary lung cancer.

摘要: Improved diagnostic imaging has the potential to guide surgeon in choice of invasive procedures required for staging and treatment lung cancer. In evaluation a solitary pulmonary nodule, absence growth 2 years or certain typical calcifications are strong evidence benignity, but we do not advocate following indeterminate nodules without diagnosis because even small may be carcinomas. In assessing chest wall invasion, computed tomography no greater predictive value than history localized pain. The nodes 1.0 cm short axis diameter on tomograms thorax is associated with low risk tumor mediastinal nodes, tissue certainty. finding larger useful guiding during procedures. Currently, there advantage magnetic resonance over nodes. Complete physical examination routine serum chemistries will identify patients at high metastases selection appropriate special studies. It emphasized that accurate requires histologic CT thorough surgical mediastinum complementary cancer.
