A Study of Treatment ALK(+) Systemic Anaplastic Large Cell Lymphoma With Crizotinib

A Multicenter Prospective Study of Treatment ALK(+) Systemic Anaplastic Large Cell Lymphoma With Crizotinib

The purpose of this study is to determine the efficacy and safety of crizotinib combined with CHOP chemotherapy for patients with ALK(+) Systemic Anaplastic Large Cell Lymphoma.

ALK(+) Systemic Anaplastic Large Cell Lymphoma patients are treated with crizotinib when they receive CHOP chemotherapy. crizotinib 250mg twice a day is administrated from day 1 of chemotherapy to 18 weeks. standard CHOP chemotherapy (cyclophosphamide, 750mg per square meter of body-surface area,d1, vincristine, 1.4mg per square meter of body-surface area, maximal dose is 2mg d1, doxorubicin, 50mg per square meter of body-surface area d1, plus prednison, 100 mg d1-5) every 3 weeks for up to six cycles.
