Summary
Brief summary (as posted)
Lung cancer remains the leading cause of mortality from malignant diseases in both men and women worldwide. Accurate diagnosis, staging and therapeutic targeting of lung cancer and other pulmonary pathology are vital with regards to providing patients with expedient and accurate treatment and treatment plans. The pre-operative evaluation and consultation in patients who are to undergo operative staging or resection for lung cancer is multidimensional and involves detailed history taking, physical examination and review of imaging studies. Two important elements of both staging and pre-operative evaluation include the evaluation of: (1) the pleural space for malignant pleural effusion and (2) the diaphragm for appropriate movement. At this point in time, the pleural space evaluation is being performed using CT scan which does not allow the acquisition of real-time cytological material from pleural effusions due to the fact that the CT scans are done in a diagnostic setting. Diaphragmatic movement/excursion is not currently being assessed pre-operatively and its impact on staging and post-operative pulmonary function is unknown. Malignant pleural effusion is recognized as a poor prognosticator in non-small cell lung cancer patients and has recently been upgraded from a T4 to an M1a status in the new edition of the AJCC NSCLC Staging System (7th Edition). The appreciation of the poor prognosis related to malignant effusion has upgraded the stage from a Stage IIIb to a stage IV. Recognizing the stage early allows for more precise prognostication of disease and can lead to precision and streamlining of treatment plans for thoracic surgeons and oncologists.
