Neuroblastoma (NB) is the most common malignant solid tumor in the peripheral nervous system in infants and young children, with a high degree of malignancy. The clinical characteristics and prognosis of NB in infants are unique. The present study retrospectively analyzed. the prognosis of infant NB cases that underwent different treatments. In total, 16 infant NB cases (10 male and 6 female) who were treated between February 2007 and August 2013 in Beijing Tongren Hospital (Beijing, China), were enrolled in the study. They were diagnosed by pathology, medical imaging and serology methods. These 16 patients were subjected to comprehensive treatment, including chemotherapy, surgery, autologous peripheral blood stem cell transplantation (APBSCT) and radiation therapy. The age distribution and clinical stages were: 5 cases (31.25%) at <= 3 months (4 cases at stage 4s and 1 case at stage 4); 2 cases (12.5%) at 3-6 months (both at stage 4s); and 9 cases (56.25%) at 6-12 months (2 cases at stage 4s, 6 cases at stage 4 and 1 case at stage 3). Subsequent to treatment, nicotinic acid esterase (NSE) levels in the patient's serum significantly decreased. The NSE levels in 12 cases (75%) dropped to the reference value (0-15.2 ng/dl). All the NB infants at stages 4s and 3 were treated by surgery and chemotherapy (100%; 9/9). The 5 NB infants at stage 4 were treated by chemotherapy and surgery. For the 2 NB infants who experienced recurrence or whose condition was partially relieved after conventional therapy, APBSCT therapy was applied. At the last follow-up in September 2014, 13 cases (81.25%) presented with a complete response, 2 cases (12.50%) with a partial response and 1 case (6.25%) with recurrence after transplantation (progressive disease). In conclusion, infant NB cases are sensitive to chemotherapy, particularly the cases at stage 4s, which occur with a higher incidence, but with a better clinical response and prognosis after treatment.
