A South American Experience With Postoperative Complications Following Chest Wall Reconstruction for Neoplasms

Abstract

Background: This study aims to report postoperative complications of chest wall reconstructions due to resections of primary or secondary neoplasms in a South American cancer institution and their association with prosthesis reconstruction.

Materials and methods: We retrospectively reviewed clinical records of patients with primary or secondary chest wall neoplasms who underwent resection and reconstruction between November 2008 and October 2018 at the Instituto Nacional de Cancerología, Bogota, Colombia.

Results: A total of 77 patients were analyzed, 50 were women (64.9%), and the median age was 45.8 years. There were 22(28.6%) sternal resections and 55(71.4%) costal resections. Prosthetic material was used in 14(18.2%) sternal and 37(48.1%) costal reconstructions. There were 26(33.7%) early postoperative complications and 16(20.8%) reinterventions. Infections were observed in 12(15.6%) patients and 4(5.2%) patients developed respiratory complications. 33.3% of all the early infections were presented in patients with methyl methacrylate (MMA) reconstructions and the same percentage in those with titanium plates. There were six (7.8%) late complications and five were related to prosthetic material extrusion, all required prosthetic material removal. The mean overall survival was 77,3 months (SD = 8 months), and 1-year and 5-year overall survival was 85% and 61%, respectively.

Conclusions: Infections were the more frequent postoperative complications in chest wall reconstructions. The use of either MMA or titanium plates was not related to early postoperative complications, although MMA reconstructions developed higher late complications and required prosthetic material removal.
