[Results of infantile neuroblastoma treatment in the Republic of Belarus]

Vopr Onkol. 2009;55(2):215-20

Authors:

Our investigation was concerned with effectiveness of infantile neuroblastoma treatment in Belarus and dependence of prognosis on extent of radical surgery. The study involved 115 patients with morphologically confirmed diagnosis of primary tumor who were treated at the Center (1997-2007). Ten-year overall and relapse-free survival rates for favorable prognosis, stage I, II, III, were 1.00 and 0.94 +/- 0.04, respectively. They were significantly higher than those for intermediate (0.70 +/- 0.09 and 0.61 +/- 0.09) or high risk (0.32 +/- 0.08 and 0.27 +/- 0.08), respectively, (p < or = 0.01). The results for radical local surgery were better: 5-year relapse-free survival--0.82 +/- 0.09 as compared with subtotal excision (0.62 +/- 0.12) and biopsy (0.5 +/- 0.25) among patients older than 12 months. Autologous stem cell transplantation (ASCT) was followed by significant improvement: 6-year overall and relapse-free survival (stage IV) (0.5 +/- 0.12 and 0.38 +/- 0.12, respectively) as compared those without ASCT (0.12 +/- 0.08 and 0.1 +/- 0.08), respectively, (p < or = 0.01). The main cause of death after ASCT was relapse. Poor results following post-ASCT treatment of stage IV tumor should be improved by more effective detection and removal of tumor cell harvest.
