Less aggressive approach to neuroblastoma still effective
5 Junho 2007
In infants and children with intermediate risk neuroblastoma, a reduced-intensity chemotherapy regimen yields survival rates comparable to or better than a more aggressive regimen typically used in this patient population, researchers report.
In a study of 467 neuroblastoma patients, 192 received 4 cycles of chemotherapy in 64 days (the less intense arm) and 275 received 8 cycles in 168 days (the standard arm), following surgery. Chemotherapy consisted of 2 to 3 drug combinations of carboplatin, etoposide, cyclophosphamide and doxorubicin.
"The bottom line is that with significantly less intense chemotherapy, we achieved 3-year overall survival of 96%," Dr. David L. Baker told the 43rd annual meeting of the American Society of Clinical Oncology.
