Objective:
To evaluate the impact of multidisciplinary intraoperative teams on surgical complications in patients undergoing sacral tumor resection.
Methods:
We reviewed all patients with primary or metastatic sacral tumors managed at a single comprehensive cancer center over a 7-year period. Perioperative complication rates were compared between those treated by an unassisted spinal oncologist and those treated with the assistance of at least 1 other surgical specialty. Statistical analysis involved univariable and stepwise multivariable logistic regression models to identify predictors of multidisciplinary management and 30-day complications.
Results:
A total of 107 patients underwent 132 operations for sacral tumors; 92 operations involved multidisciplinary teams, including 54% of metastatic tumor operations and 74% of primary tumor operations. Patients receiving multidisciplinary management had higher body mass indexes (29.8 vs. 26.3 kg/m2; P = 0.008), larger tumors (258 vs. 55 cm³; P < 0.001), and higher American Society of Anesthesiologists scores (3 vs. 2; P = 0.049). Only larger tumor volume (odds ratio [OR], 1.007 per cm³; P < 0.001) and undergoing treatment for a malignant primary versus a metastatic tumor (OR, 23.4; P < 0.001) or benign primary tumor (OR, 29.3; P < 0.001) were predictive of multidisciplinary management. Although operations involving multidisciplinary teams were longer (467 vs. 231 minutes; P < 0.001) and had higher blood loss (1698 vs. 774 mL; P = 0.004), 30-day complication rates were similar (37 vs. 27%; P = 0.39). On multivariable analysis, only larger tumor volume (OR, 1.004 per cm³; P = 0.005) and longer surgical duration (OR, 1.002 per minute; P = 0.03) independently predicted higher 30-day complications.
Conclusions:
Although patients managed with multidisciplinary teams had larger tumors and worse baseline health, 30-day complications were similar. This finding suggests that the use of multidisciplinary teams may help to mitigate surgical morbidity in those with high baseline risk.
