Background
Primary extended resection has been proposed as the initial treatment for patients with retroperitoneal sarcoma. This approach comprises an extended en-bloc resection of the directly infiltrated organs and adjacent uninvolved organs. The results of such radical surgery have yet to be validated. This retrospective study aims to investigate this practice in a contemporary series from a referral center in the UK.
Methods
We extracted data from consecutive patients who underwent extended resectional surgery between 2009 and 2013, and investigated the type of resection performed, the effectiveness of extended surgery in providing negative microscopic margins, and the occurrence of post-surgical adverse events.
Results
A total of 69 patients were included. Fifty-two patients had a primary tumor (75.4 %), and in 55 patients (79.7 %) the tumor was resected en bloc with adjacent organs or structures. Colonic resection (N = 35, 50.7 %) and nephrectomy (N = 28, 40.6 %) were the most frequently performed organ resections. Organs were infiltrated in 22 patients (32 %), and there was no association between organ infiltration and patient variables and staging characteristics. Negative microscopic margins were achieved in 88.6 % of patients in this series. Postoperative complications occurred in 21 patients (30 %) and a reoperation was required in ten cases (14.5 %). No independent predictors of morbidity were identified and no 30-day postoperative deaths occurred.
Conclusions
Four-fifths of patients in this series had organs removed in association with the retroperitoneal sarcoma. This approach in a specialist sarcoma unit results in negative microscopic tumor margins in up to 90 % of cases and can be performed safely.
