Background:
An aggressive surgical approach to locally advanced malignancy is being increasingly used in the absence of distant metastatic disease. This includes resection and reconstruction of major venous structures. We investigated the results of using a multidisciplinary surgical approach in these instances.
Methods:
The study data were obtained from a university-affiliated hospital from January 1, 2006, to December 31, 2012. All patients who underwent an oncologic resection using a multidisciplinary approach with vascular surgery consultation were included in the analysis. Primary outcomes analyzed included rate of margin positivity, postoperative venous patency, and survival. Secondary outcome measures included operative time, estimated blood loss, and length of hospital stay.
Results:
A total of 23 patients met criteria for study. Venous involvement included the portal and/or superior mesenteric vein and inferior vena cava in 14 and 9 patients, respectively. Nine patients had clear vascular involvement before surgery and received preoperative consultation. Overall margins were positive in 56.5%, whereas the rate of vascular margin positivity was 30.4%. The postoperative venous patency rate was 65.0%. There were no perioperative mortalities, and median survival was 10 months (range, 4-80).
Conclusions:
Major venous resections and reconstructions in oncologic surgery are safe but associated with a high rate of positive margins. Future efforts should focus on identifying patients in the preoperative phase to provide opportunity for optimal multidisciplinary planning.
