Comparative study on the efficacy of Hyper CVAD/MA regimen and CHOP or CHOP like regimen in the treatment of primary peripheral T cell lymphoma / 中华血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the curative efficacy and safety of two regimens, Hyper CVAD/MA and CHOP/CHOP, in the treatment of primary peripheral T cell lymphoma (PTCL).</p><p><b>METHODS</b>The clinical data of 80 primary PTCL patients were retrospectively analyzed, and the efficacy and safety of the two regimens, Hyper CVAD/MA and CHOP/CHOP, were evaluated.</p><p><b>RESULTS</b>Of 80 patients with primary PTCL, 23 were treated with Hyper CVAD/MA regimen (HM group, experimental group) and 57 with CHOP or CHOP-like regimen (CC group, control group). The differences between overall response rate (ORR) among HM group and CC group (78.3% vs 54.4%, P = 0.047), ORR in patients with IPI score of 0-2 (86.7% vs 55.2%, P = 0.037), courses of chemotherapy to achieve remission (4 vs 6, P = 0.004), median progression-free survival (PFS) time (24 months vs 12 months, P = 0.039) and 1- year PFS rate (82.6% against 45.6%, P = 0.006) were statistically significant. The relapse rates were similar between 2 groups (50.0% vs 54.8%, P = 0.744). The 2-year and 3-year progression-free survivals and 3 year overall survival were not significantly different (P > 0.05). Patients in Hyper CVAD/MA group are more susceptible to neutropenia (<1.5 × 10⁹/L) (73.9% vs 38.6%, P=0.004).</p><p><b>CONCLUSION</b>The curative effect of Hyper CVAD/MA regimen as induction therapy in treatment of PTCL patients except ALK positive PTCL patients was better than that of CHOP/CHOP-like regimen.</p>
