The supraclavicular approach in the management of cervicothoracic-junction benign neurogenic tumors: A real-world analysis

Objectives The study objectives were to evaluate the safety, feasibility, and risk of neurologic complications with the supraclavicular approach in the operative management of cervicothoracic-junction benign neurogenic tumors. Methods Between January 2012 and April 2023, 115 patients who underwent surgical resection for cervicothoracic-junction benign neurogenic tumors were retrospectively enrolled. Patients were divided into 3 groups based on the surgical approach: supraclavicular alone (Supraclav-Alone), n = 16; Transthoracic-Alone (video-assisted thoracoscopic surgery/Open), n = 87; and supraclavicular combined with transthoracic (Supraclav + video-assisted thoracoscopic surgery/open), n = 12. Clinicopathologic variables and postoperative morbidity including neurologic complications were summarized among the groups. Logistic regression analysis was performed to identify predictors for long-term (>6 months) brachial plexus injuries. Results The cohort comprised 28 patients (24.3%) who underwent surgical resection using a supraclavicular approach. The Supraclav-Alone group portended the most cephalad location of tumor, the smallest pathologic tumor size, the shortest operative time, the least blood loss, and the least postoperative pain. The incidence of surgical complications, phrenic nerve neuropraxia, recurrent laryngeal nerve neuropraxia, or Horner’s syndrome was similar among the groups postoperatively. However, use of the supraclavicular-alone approach (adjusted odds ratio, 0.165; 95% CI, 0.017-0.775) was a predictor for long-term brachial plexus injury complications. Among patients who experienced brachial plexus injury complications, the proportion of patients achieving complete resolution was higher among those undergoing a supraclavicular approach group (Supraclav-Alone: 80.0% vs Supraclav + video-assisted thoracoscopic surgery/Open: 60.0% vs video-assisted thoracoscopic surgery/Open: 25.8%). Conclusions The supraclavicular approach may be a safe and feasible strategy in the management of cervicothoracic-junction benign neurogenic tumors that does not increase surgical complications and minimizes the severity of brachial plexus injury.
