Preferred Label : Lung Cancer pM1a TNM Finding v7;
NCIt related terms : pM1a;
NCIt definition : Lung cancer with separate tumor nodule(s) in a contralateral lobe; tumor with pleural
nodules or malignant pleural (or pericardial) effusion. Most pleural (and pericardial)
effusions with lung cancer are due to tumor. In a few patients, however, multiple
cytopathologic examinations of pleural (or pericardial) fluid) are negative for tumor,
and the fluid is nonbloody and is not an exudate. Where these elements and clinical
judgment dictate that the effusion is not related to the tumor, the effusion should
be excluded as a staging element and the patient should be classified as M0. (from
AJCC 7th Ed.);
