AimThe study aims to evaluate survival outcome in newly diagnosed pediatric intermediate risk neuroblastoma patients treated at the Children Cancer Hospital – Egypt and their relation to various clinical and pathological factors.MethodsThe study included stage 3 patients <1.5 years, children 1.5 years or older with stage 3 disease and favorable histopathological features, infants (<1 year) with International Neuroblastoma Staging System (INSS) stage 4 disease, stage 4 children 1–1.5 years with favorable biology, and infants stage 4 s (with unfavorable biologic features). Patients received systemic chemotherapy, in the form of etoposide and carboplatin alternating with cyclophosphamide, doxorubicin and vincristine, administered at 3-week intervals, with a total of 6 or 8 cycles guided by reaching objective overall response (complete/very good partial/partial response).ResultsThe study included 136 patients, 67 males and 69 females. 101 patients had abdominal primary tumors, 28 had mediastinal masss and 7 with masses in the neck; 68% were stage 3 and the remaining (n = 44) had metastatic disease.The three-year overall survival (OS) and event-free survival (EFS) estimates were 94% ± 2% and 90.9% ± 2.5%, respectively. OS and EFS by gender, age, pathology and INPC were all statistically not significantly different. Moreover, OS for patients having surgery versus no surgery (inoperable residual only) was statistically significant (98.4% ± 1.6% & 88.7% ± 5.3%, respectively, p = .034).ConclusionA very high rate of survival is currently achievable in patients with intermediate risk neuroblastoma by chemotherapy or chemotherapy and surgery. In addition to response, our plan is to adopt biologically-based treatment to reduce treatment-induced complications among survivors.
