| Abstract: | Background: We used a novel regimen for neuroblastoma (NB) that had responded inadequately to standard chemotherapy which now includes topotecan in induction or second-line therapy. Patients and methods: We retrospectively studied 38 patients who received one or two courses of high-dose cyclophosphamide (140 mg/kg)-irinotecan (CPT-11) (250 mg/m2)- vincristine (HD-CCV) as treatment for NB that had responded incompletely to induction but had never progressed. Treatment was outpatient and was preceded and followed by extent-of-disease and toxicity evaluations because the patients were being considered for enrolment on formal protocols. Progression-free survival (PFS) was calculated from day 1 of HD-CCV. Results: Common toxicities were grade 4 myelosuppression and grade 2 diarrhoea. Responses - 5 complete (CR), 3 partial (PR), 4 mixed (MR) - occurred in 12/28 (43%) patients treated ≤9 months, and in 1/10 (10%) patients treated >10 months, from diagnosis. HD-CCV was the initial salvage regimen after topotecan-containing induction in 5 patients, achieving 1 CR, 1 MR and 3 stable disease (NR). HD-CCV produced responses (2 PR, 3 MR) in all 5 patients previously treated with CPT-11/ temozolomide. In contrast, all 6 patients treated post-HD-CCV with CPT-11/temozolomide had NR to the latter. Post-HD-CCV treatments included immunotherapy, targeted radiotherapy and/or chemotherapy. PFS was 64% (±8%) at 24 months, with 20 patients progression-free at 2+-to-36+ (median 16+) months and 10 in first CR at 9+-to-36+ (median 16+) months. Conclusions: HD-CCV offers a treatment option against topotecan-resistant NB. Results support the concept that combining CPT-11 with very high doses of alkylators can yield greater antitumour effect. © 2010 Elsevier Ltd. All rights reserved. |
