title: G-CSF for the prophylaxis of neutropenic fever in patients with small cell lung cancer receiving myelosuppressive antineoplastic chemotherapy: meta-analysis and pharmacoeconomic evaluation.
abstract: Standard meta-analytical and pharmacoeconomic techniques were used to study the clinical effectiveness and the cost-effectiveness ratio of the prophylactic (or pre-emptive) administration of G-CSF to patients with small cell lung cancer treated with conventional myelosuppressive cytotoxic chemotherapy. In the first part of our study, we conducted a meta-analysis of the randomized clinical trials evaluating G-CSF for this clinical indication. Three trials were identified by our literature search and were included in the meta-analysis (overall number of patients = 606). The end-points for evaluating G-CSF included mortality from infection and the cumulative incidence of neutropenic fever over six cycles of chemotherapy. The results of our meta-analysis demonstrate that prophylactic G-CSF did not affect mortality but significantly reduced the incidence of neutropenic fever from 68.3% to 38.7% (pooled odds ratio = 0.29, 95% CI: 0.21-0.40; P < 0.001). In the second part of our study, we carried out a pharmacoeconomic analysis to estimate the cost-effectiveness ratio of pre-emptive G-CSF (i.e. the 'average' cost associated with the prevention of an episode of neutropenic fever). This cost-effectiveness ratio was US$ 14,372 using the Italian price of the drug converted into dollars, or US$ 41 088 using the US price. Finally, we estimated the revenue-neutral price of G-CSF based on American data of the cost-of-illness. The price ranged from US$ 395 to US$ 569 per cycle, a figure higher than the value (US$ 150) previously reported in the literature.
