BACKGROUND Squamous cell carcinomas (SCC) account for approximately 30% of non-small cell lung cancer (NSCLC). Current staging methods do not adequately predict outcome for this disease. EMX2 is a homeo-domain containing transcription factor known to regulate a key developmental pathway.

PURPOSE To evaluate the diagnostic accuracy of multidetector computed tomography (MDCT) for preoperative staging of renal cell carcinoma (RCC) using the 1997 TNM (tumor, node, metastasis) classification. MATERIALS AND METHODS We conducted a retrospective review of MDCT in 57 consecutive patients with RCC performed for tumor staging before radical (n = 51) or partial nephrectomy (n = 6). The s...
