Outcomes of total versus partial resection. Kaplan-Meier (KM) analysis for progression-free survival probability in total and partial resection of lipoma. The progression-free probability for total resection is 88.1% at 20 years, and 34.6% for partial resection at 10.5 years. The difference is highly significant (p<0.0001 by log-rank & Wilcoxon). Note stabilization of disease after 8 years with total resection, but inexorable deterioration without disease arrest with partial resection.
