A, An overall survival of 50% was reached at 28.0 months (95% CI, 21.3-34.7 months). Mean (SD) 5-year overall survival was 23.0% (6.4%), while mean (SD) 10-year overall survival was 11.3% (5.5%). B, A disease-specific survival of 50% disease-specific survival was reached at 33.0 months (95% CI, 0.9-45.1 months). Mean (SD) 5-year disease-specific survival was 30.5% (7.6%) and mean (SD) 10-year disease-specific survival was 25.9% (7.1%). C, Mean (SD) 5- and 10-year progression-free survival were 5% (1.3%) (95% CI, 2.5-7.3 years). D, Median time from metastasis to death was 12 months (95% CI, 3.8-20.2 months).
