OBJECTIVE: To compare the surgical outcomes of benign and malignant carotid body tumor (CBT), and to evaluate the associated factors of malignant CBT.
METHODS: Patients who underwent surgical resection of CBT from 2005 to 2018 in a tertiary center were reviewed retrospectively. The common study follow-up end date was December 31, 2019. The tumor size was measured as the maximum transverse diameter on computed tomography scan. Surgical outcomes of benign and malignant CBT were compared. Associated factors of malignancy were analyzed by multivariate logistic analysis.
RESULTS: There were 229 patients undergoing CBT resection. Sixteen patients were diagnosed with malignant CBT. The median follow-up time was 66 months (range, 6-142 months). Basic information including age, sex, course of disease, family history, lesion side, tumor size, and Shamblin classification showed no significant differences between the benign and malignant CBT groups. Patients with malignant CBTs showed a higher rate of preoperative symptoms (31.3% vs 12.2%; P < .05). The rates of vascular reconstruction or repair (P < .01) and neurologic complications (P < .05) were significantly higher in the malignant CBT group. In addition, a significantly longer average procedural time was required for malignant CBTs (P < .05). However, the estimated blood loss and length of hospital stay showed no significant difference. Multivariate logistic regression analysis revealed that the malignant odds of CBT with bilateral lesions (P = .0042; odds ratio, 8.30; 95% confidence interval, 1.84-35.88) or CBT with preoperative symptoms (P = .0016; odds ratio, 7.59; 95% confidence interval, 2.13-27.89) were high.
CONCLUSIONS: Compared with benign CBT, malignant CBT is prone to invasive clinical behaviors, resulting in an increased possibility of vascular reconstruction or repair during the surgery as well as postoperative neurologic complications. In addition, the malignant odds of CBT with bilateral lesions or CBT with preoperative symptoms are high.
