Figure 4. — Kaplan–Meier disease-specific survival for 189 patients with clinical stages IIB, IIIA, IIIB, and IIIC disease and adequate follow-up. Comparison of patients with and without distant metastases on fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸FDG-PET-CT). The upper curve (in green color online) shows patients without distant metastases (n = 142; events = 7). The lower curve (in blue color online) shows patients with distance metastases detected by PET-CT (n = 47; events = 13). Log-rank P less than .001.
