Clinical researches about the management and outcomes of ganglioneuroma and ganglioneuroblastoma-intermixed are limited. We report the surgical outcomes of ganglioneuroma and ganglioneuroblastoma-intermixed in a single institution.
Ganglioneuroma and ganglioneuroblastoma-intermixed diagnosed and resected between May 2009 and May 2015 in a tertiary children’s hospital were retrospectively reviewed. Patients’ demographic data, INSS stage, surgical complications, residual tumor size and outcomes were collected.
Thirty-four patients were included in the current study. All had localized tumors and were surgically managed. The overall acute complications rates were 8.8% (3/34) and none were fatal. Thirty-three of 34 patients had at least macroscopic tumor resection. Six patients had radiographically detected residual tumor after surgery, 25 none and 3 undocumented. Thirty-three (97.1%) patients were alive during a median follow-up of 36 months (range 1–82). In subgroup analysis, no significant difference regarding surgical complications and survival was found between ganglioneuroma and ganglioneuroblastoma-intermixed. Increased complete resection rates were observed in thoracic tumor compared with abdominal ones (p = 0.03). However, no significant difference (p = 0.089) regarding overall survival was found between patients with residual tumors and those without. Of the six patients with residual tumors, three showed complete resolution, two were unchanged and one died 3 years after initial surgery (the only death in this study).
Ganglioneuroma and ganglioneuroblastoma-intermixed can be safely and effectively resected, the residual tumor seems not to influence overall survival.
