Abstract
BackgroundPreoperative bevacizumab has been reported to increase postoperative complication risk following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We sought to review our experience with preoperative bevacizumab in patients undergoing CRS/HIPEC for peritoneal surface malignancy.MethodsThis is a retrospective review of patients who received neoadjuvant systemic therapy with or without bevacizumab prior to CRS/HIPEC at a high-volume academic center from 2007–2018.ResultsOf 499 patients, a total of 88 patients received neoadjuvant chemotherapy alone (n = 34) or in combination with bevacizumab (n = 54) within 3 months prior to CRS/HIPEC. No differences existed in 60-day major morbidity (17.6 vs. 16.7%, p = 0.81) or 60-day mortality (0 vs. 0%) between the two cohorts, and neoadjuvant bevacizumab was not associated with increased odds of overall complications (OR 0.86, 95% CI 0.35–2.09, p = 0.73) or major morbidity (OR 0.86, 95% CI 0.24–3.00, p = 0.81). Stratifying patients by primary tumor origin and post-operative complications did not reveal any significant differences between the two treatment groups. In addition, progression-free survival (PFS) and overall survival (OS) were similar in both cohorts.ConclusionsPreoperative bevacizumab is not associated with increased morbidity or mortality following CRS/HIPEC. Neoadjuvant therapy employing this biologic agent is safe and should not be a deterrent for aggressive cytoreduction with curative intent.
Highlights
Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is commonly employed in the management of peritoneal surface malignancies
No differences existed in 60-day major morbidity (17.6 vs. 16.7%, p = 0.81) or 60-day mortality (0 vs. 0%) between the two cohorts, and neoadjuvant bevacizumab was not associated with increased odds of overall complications or major morbidity
Preoperative bevacizumab is not associated with increased morbidity or mortality following CRS/HIPEC
Summary
Preoperative bevacizumab has been reported to increase postoperative complication risk following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/ HIPEC).
