RESUMEN
Objective To investigate the effect of the extent of surgical resection on the prognosis of children patients with advanced neuroblastoma. Methods Thirty-seven children patients with advanced neuroblastoma were selected as our subjects,who underwent surgical treatment in the People's Hospital Binzhou from Jan. 2001to Dec. 2006. All the patients were treated with surgical operation or surgical operation combined with chemotherapy,among them 24 cases were completely removal,and 13 cases were partially removal. All patients were followed-up for more than 5 years. Log rank test and multivariate COX regression analysis were used to explore the effect of surgery resection on prognosis. Results The influencing factors of the complete resection group included lymphatic metastasis,clinical stage,combined with chemotherapy,tumor markers neuronspecific enolase(P = 0. 002,0. 000,0. 019,0. 015 respectively). COX regression analysis showed that the independent factors included chemotherapy( OR = 1. 952,95% CI = 1. 258 - 2. 759,P = 0. 000),lymph node metastasis(OR = 2. 856,95% CI = 1. 356 - 3. 859,P = 0. 019),and extent of surgical resection(OR = 3. 069, 95% CI = 1. 585 - 4. 685,P = 0. 005). The shortest survival period of patients in this study was a month,and the median survival period was 33. 96 months. One year survival rate was 62. 21% and 2-year survival rate was 41. 09% as well as 3-year survival rate was 23. 59% . The average survival period between total and partial of surgical resection was significant((56. 96 ± 13. 22)months,(19. 63 ± 10. 20)months;P = 0. 019). Conclusion Surgical resection is an important factor of the prognosis of patients with NB. If the patient's own conditions permit,it can be appropriate to expand the scope of surgical resection in order to reduce the risk of tumor recurrence.
