The efficacy of delayed surgery in children with high-risk neuroblastoma

Surgery is an important part of treatment in children with neuroblastoma; however, exact timing is unclear. Both initial and delayed surgery was suggested as the best by numerous studies. Thus, we aimed to investigate the role of delayed surgery on 31 children with high-risk neuroblastoma. Thirty-on...

Description
Summary:Surgery is an important part of treatment in children with neuroblastoma; however, exact timing is unclear. Both initial and delayed surgery was suggested as the best by numerous studies. Thus, we aimed to investigate the role of delayed surgery on 31 children with high-risk neuroblastoma. Thirty-one children with high-risk neuroblastoma were enrolled into the study. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) for windows 10.0. There 'were 15 male and 16 female patients with a median age of 3.0 ± 3.2 years. Primary tumor site was adrenal in 27, non-adrenal in two, pelvic in one, and mediastinal in one patient. MYCN gene was amplified in four and non-amplified in 11 children on totally 15 children with available data. Lactate dehydrogenase was elevated in 30 children. The tumor volumes at diagnosis and before surgery in the whole group were 154.3 and 12.5 mL, respectively. The decline in tumor volume was statistically significant (P < 0.0001). Initial surgery was performed in three and delayed in 20 children, and eight children were inoperable. Surgical complication rate was 66.6% (two out of three patients) in initial surgery group; however, the rate was 15% (3 out of 20 patients) in delayed surgery group. The 5-year event-free survival and overall survival rates in the whole group were 44.8% and 50.8%, respectively. Primary tumor area control rate was 95% In conclusion, the delayed surgery with intensive chemotherapy and radiotherapy has been successful for primary control in high-risk neuroblastoma patients.
