“…Large prospective series did indicate a higher relapse rate and a poorer survival for PTCL than DLBCL [2,[5][6][7][8][9][10][11][12][13]. Various chemotherapy regimens have been tried out--such as MegaCHOP (intensive or higher dose of CHOP) with or without etoposide [14,15], epirubicin substituted for doxorubicin and addition of bleomycin (CEOP-B) [16], CMED (cyclophosphamide, etoposide, methotrexate, and dexamethasone) [17], CHOP or MegaCHOP/ESHAP (etoposide, cisplatin, cytarabine and prednisone) [18,19] and VCAP-AMP-VECP (vincristine, cyclophosphamide, doxorubicin, and prednisone (VCAP); doxorubicin, ranimustine, and prednisone (AMP); vindesine, etoposide, carboplatin, and prednisone (VECP)) [20]; fractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone alternating with high doses of methotrexate and cytarabine (hyperCVAD) [21,22]--with no superior efficacy to CHOP except CMED at the expense of higher treatment toxicity. Gemcitabine-based chemotherapies are emerging and seem quite compromising [23][24][25][26][27].…”
