MATERIALS AND METHODS
Between March 1985 and July 1987, 146 patients with potentially resectable NSCBC were prospectively subjected to evaluation for extrathoracic, neoplastic extension at the Thoracic Unit of the “Reina Sofia” Hospital, Cordoba, Spain (Table 1). The following patient categories were excluded from this study: (1) those who were first being seen because of symptoms secondary to extrathoracic presentation of the disease; (2) those with metastasis easily evaluated by means of physical examination
RESULTS
In 44 (30 percent) of 146 patients, extrathoracic metastases were detected in at least one organ, and in 17 patients (11.6 percent) the disease was multiorganic.
The metastases found were located in the following: brain, 19 cases (13 percent); bone, 19 cases (13 percent); liver, 18 cases (12.3 percent); adrenals, 11 cases (7.5 percent); kidney, two cases (1.4 percent); and subdiaphragmatic nodules, two cases (1.4 percent).
The histologic analysis revealed metastases in 42 percent (13/31) of the
DISCUSSION
The purpose of this study was to determine the value of routine extrathoracic staging in patients with potentially resectable NSCBC. In this way, the clinical and laboratory data suspect for metastasis were prospectively registered. Modern diagnostic imaging techniques were used on the organs and systems more often affected by this type of tumor. To obtain practical conclusions about what study should be done and when, every patient included in this series was subject to all techniques

2016, Journal of Thoracic OncologyCitation Excerpt :None of the 121 patients in this study with stage Ia or Ib lung SCC had BM. Similarly, an early study evaluating BM in subjects with NSCLC using brain CT showed that subjects with stage I or II SCC had no BM.13 We provided more accurate data with more patients by using brain MRI because the numbers in the previous study might have been insufficient for detection of rare events and because brain CT is less sensitive than brain MRI for detecting early BM (i.e., BM in subjects with stage II lung SCC).6
