Abstract:
Objectives To analyze the clinical features and long-term follow-up results of neuroblastoma (NB) without chemotherapy and radiotherapy, and to provide evidence for further improvement of treatment. Methods The clinical data of children diagnosed with NB who received operation during January 2005 to December 2015 was retrospectively analyzed, and the long-term follow-up results were evaluated. Results In 57 cases of NB, 43 cases (81.1％) were in stage 1, 8 cases were in stage 2 and 2 cases were in stage 4S. The median age at diagnose was 7 months (11 days - 10 years and 11 months). There were 47/51 cases had the pathological type with a good prognosis (accounting for 92.2％). FISH was detected in 1/49 case which had the amplification at greater than 10 copies. 56/57 cases underwent surgical resection of the primary tumor, 50 cases of which were completely resected, and 3 cases had very good partial remission after tumor resection. The abdominal mass was found in the uterus in 1 case, and surgical operation was not performed and the imaging was regularly checked for follow-up , and the mass subsided completely at 7-month-old. The median follow-up time was 36 months (4 - 99 months). Five children were lost to follow-up and the median time of follow-up was 19 months (4 - 45 months). One child in stage 4S relapsed at 1 year of follow-up, 2 cases in stage 1 relapsed at 6 months of follow-up. Five years event free survival rates (EFS) in all patients were 94.6％, and overall survival rate (OS) of the 5 years was 100％. Conclusions Children younger than 18 months without MYCN amplification in the stages 1 and 2 are safe by surgical treatment alone with good prognosis. Simple surgical treatment can also be extended to all age groups of NB without MYCN amplification in the stages 1 or 2.
