Abstract
Methods
In this retrospective trial, we analyzed data of patients with relapsed/refractory lymphoma who received outpatient fractionated ICE between 2011-2017 at a tertiary care center. The three weekly ICE protocol consisted of: ifosfamide 1500 mg/m(2) infused over 2 h on days 1-3, carboplatin (5 AUC) on day 1, and etoposide 100 mg/m(2) on days 1-3. Rituximab 375 mg/m(2) was given to patients with CD20 positive B cell Non-Hodgkin lymphoma.
Results
Total of 89 patients were included in this research project. Majority of patients had Hodgkin lymphoma (64%). Mean number of ICE cycles received was 2.5. Complete remission and partial remission rates for primary refractory (62.9%) and non-primary refractory (36.4%) disease were 10.5% and 26.3% versus 41.9% and 29.0% respectively. Event free survival rate was 14.5 months (95% CI 7.7-28.0) and overall survival rate 88.7 months (95% CI 48.1-NR). Grade 3 hematological toxicities were documented in 19.1% of patients with 10.1% experiencing neutropenia and 9% thrombocytopenia. 5.6% had febrile neutropenia.
Conclusions
Our study included, to our knowledge, the largest number of patients treated with outpatient fractionated ICE. Results demonstrated that this regimen might be a reasonable replacement for classic ICE regimen in many patients with lymphoma. It has a favorable safety profile. However, patients with primary refractory lymphomas need more effective regimens.
