Figure 1.

Proportion without relapse after resection. The proportion of patients without relapse over time is shown for the two time periods. In the first period only 6 of 16 resected patients had complete resections (37.5%), 10 have relapsed immediately. In the second time period 31 of 53 patients had complete resections (58.5%), 22 had relapsed immediately. Similarly during further follow-up, time to relapse after resection remained increased for the second time period (p = 0.064).
