Thirty-six of the 39 patients receiving imatinib were alive at 6 months and were included in a landmark analysis for overall survival (OS) according to response status at 6 months. In this analysis responders were those patients included in the ORR reported in Table 3, not corrected for steroid sparing. The 36-month OS was significantly higher for responders (dotted line) than for nonresponders (solid line): 94% vs 55%, 100% vs 60%, and 94% vs 58% according to changes in NIH SS (A), Center Response (B), and NIH criteria (C), respectively.
