Background:
We investigated whether concomitant organ removal as part of the primary resection of RP WDLPS confers an outcome advantage in patients treated at a major sarcoma center.
Methods:
The departmental sarcoma database was reviewed to identify patients with RP WDLPS who underwent initial surgical resection for primary disease at MD Anderson Cancer Center during the study period 1995-2011. We retrospectively reviewed medical records and examined associations between clinicopathologic variables and overall survival (OS) as well as disease-free survival (DFS).
Results:
Among 83 patients included in this study, 76 patients (92%) underwent complete resection (R0/R1). Concomitant organ resections were performed in 38 patients (46%). Invasion of the resected organ/s was seen in six patients (7%). Estimated OS was 11.3 years (5-year OS, 86%), and DFS was 5.4 years (5-year DFS, 51%). By multivariate analysis, concomitant organ resection was not associated with improved OS (P = 0.428) or DFS (P = 0.946), and lack of organ resection was associated with a lower risk of postoperative complications (P = 0.01).
Conclusions:
Concomitant organ resection was not associated with a survival benefit in RP WDLPS in this study. In patients with primary RP WDLPS, we recommend selective resection of contiguous organs only if there is clinical suspicion of invasion.
