The Kaplan-Meier 5-year survivorship estimate curves among patients with unplanned excisions based on disease status at tumor bed excision show decreased (p = 0.015) local recurrence-free survival in patients with microscopic (61.3%; 95% CI, 44.7%–75.8%) or gross residual disease (0%; 95% CI, 0%–48.3%) versus no residual disease (94.4%; 95% CI, 70.6%–99.7%). The plus signs (no residual disease), solid circles (microscopically positive residual disease), and solid triangles (gross residual disease) along the curves represent censored patients.
