Comparative Effectiveness of Minimally Invasive Surgery vs Open Surgery in neuroblastoma

Abstract

Purpose: To explore the feasibility of minimally invasive surgery（MIS）used in the treatment of neuroblastoma. Methods: Selected NB patients were randomly assigned to the MIS group and the open surgery（OS） group. The operative details, major complications, and prognosis of the two groups were compared. Results: A total of 35 children undergoing MIS and 35 children undergoing open surgery were enrolled in this study. According to the INRGSS staging system, 30 patients were classified as stage L1, 32 as stage L2, and 8 as stage M. No statistical difference was found in the age of the children and the maximum diameter of the primary site tumor between the two groups. The bleeding volume in the OS group was significantly higher than that in the MIS group (P=0.006), The time to start postoperative feeding in the MIS group was significantly shorter than that in the OS group (P<0.001). No significant difference was found in the number of GTR between the MIS group and the OS group (P=0.246). The one-year survival rate and overall survival rate of the MIS group were 100% and 93.85%, while the OS group was 100% and 93.72%, respectively. Conclusion: MIS has more advantages than OS for suitable neuroblastoma, while the prognosis is almost the same. After gradually improving the indications for MIS, it should become the preferred surgical method for children within this range.
