1 Phase I and pharmacologic study of high doses of the topoisomerase I inhibitor topotecan with granulocyte colony-stimulating factor in patients with solid tumors. Topotecan colony stimulating factor 3 Homo sapiens
2 PURPOSE: To evaluate the feasibility of escalating doses of the topoisomerase I (topo I) inhibitor topotecan (TPT) with granulocyte colony-stimulating factor (G-CSF) in minimally pretreated adults with solid tumors and to study whether G-CSF scheduling variably affects the ability to escalate TPT doses. Topotecan colony stimulating factor 3 Homo sapiens
3 PURPOSE: To evaluate the feasibility of escalating doses of the topoisomerase I (topo I) inhibitor topotecan (TPT) with granulocyte colony-stimulating factor (G-CSF) in minimally pretreated adults with solid tumors and to study whether G-CSF scheduling variably affects the ability to escalate TPT doses. Topotecan colony stimulating factor 3 Homo sapiens
4 PURPOSE: To evaluate the feasibility of escalating doses of the topoisomerase I (topo I) inhibitor topotecan (TPT) with granulocyte colony-stimulating factor (G-CSF) in minimally pretreated adults with solid tumors and to study whether G-CSF scheduling variably affects the ability to escalate TPT doses. Topotecan colony stimulating factor 3 Homo sapiens
5 However, dose escalation of TPT with G-CSF on a posttreatment schedule proceeded to 4.2 mg/m2/d. Topotecan colony stimulating factor 3 Homo sapiens
6 CONCLUSION: G-CSF administered after 5 daily 30-minute infusions of TPT permits a 2.3-fold dose escalation of TPT above the MTD in solid-tumor patients, whereas concurrent therapy with G-CSF and TPT results in severe myelosuppression. Topotecan colony stimulating factor 3 Homo sapiens
7 CONCLUSION: G-CSF administered after 5 daily 30-minute infusions of TPT permits a 2.3-fold dose escalation of TPT above the MTD in solid-tumor patients, whereas concurrent therapy with G-CSF and TPT results in severe myelosuppression. Topotecan colony stimulating factor 3 Homo sapiens
8 CONCLUSION: G-CSF administered after 5 daily 30-minute infusions of TPT permits a 2.3-fold dose escalation of TPT above the MTD in solid-tumor patients, whereas concurrent therapy with G-CSF and TPT results in severe myelosuppression. Topotecan colony stimulating factor 3 Homo sapiens
