Modified ice study: a phase II study of an intensive, modified ICE regimen (ifosfamide, carboplatin and etoposide) in patients with better prognosis, small cell lung cancer.
A total of 30 with good prognosis small cell lung cancer were treated with a modified 'ICE' (ifosfamide, carboplatin and etoposide) chemotherapy regimen in an attempt to achieve a high response rate with less toxicity than is seen with the full 'ICE' regimen. This was given every 4 weeks for a maximum of six cycles. In total 25 patients (83%, 95% CI (70-97%)) experienced a partial or complete response at some stage of their treatment. Of these patients, 12 (40%, 95% CI (22-58%)) showed a complete response. A total of 19 patients (63%) had to have their dose reduced and/or delayed at some point due to toxicity. Nadir blood counts showed that 19 patients (63%, 95% CI (46-81%)) had WHO grade 3 or 4 thrombocytopenia, and 24 (86%, 95% CI (73-99%)) had grade 3 or 4 neutropenia. A total of 17 patients (53%) completed six cycles of chemotherapy. In total 3 patients died during treatment all due to treatment-related complications. Median survival was 12.6 months (95% CI (11.6, 14.7 months)). Nausea, vomiting, dysphagia, activity, mood and overall condition, as recorded using daily diary cards, were worse at the beginning of each chemotherapy cycle. Both response rates and survival were clinically acceptable. However, neutropenia and thrombocytopenia, although reduced from rates reported with the full ICE regimen, were still high. A prospective randomised controlled trial is now needed to assess this regimen in more detail.
