Abstract

Neuroendocrine liver metastases (NELM) are typically associated with high recurrence rates following surgical resection. Conditional disease-free survival (CDFS) estimates may be more clinically relevant compared to actuarial survival estimates.CDFS was assessed using a multi-institutional cohort of patients. Cox proportional hazards models were used to evaluate factors associated with disease-free survival (DFS). Three-year CDFS (CDFS3) estimates at "x" year after surgery were calculated as CDFS3 ?=?DFS(x?+?3)/DFS(x).A total of 521 patients met the inclusion criteria. While actuarial 3-year DFS gradually decreased from 49% at 1 year to 39% at 5 years, CDFS3 increased over time. CDFS3 at 5 years was estimated as 89% vs actuarial 8-year DFS of 39% (P?
