NCIt definition : Lung cancer with separate tumor nodule(s) in a contralateral lobe; tumor with pleural
or pericardial nodules or malignant pleural or pericardial effusion. Most pleural
(pericardial) effusions with lung cancer are a result of the tumor. In a few patients,
however, multiple microscopic examinations of pleural (pericardial) fluid are negative
for tumor, and the fluid is nonbloody and not an exudate. If these elements and clinical
judgment dictate that the effusion is not related to the tumor, the effusion should
be excluded as a staging descriptor. (from AJCC 8th Ed.);
