“…Patients with any stage of disease were accepted in the study. Therapy differed as follows: Seven patients with Stage I disease who had a very favorable clinical presentation underwent extended-field radiotherapy alone; 53 patients with Stage I and II disease who had no more than 1 factor present among extranodal lesion, ESR Ͼ40 mm at the first hour, and LDH higher than normal level, received chemotherapy with vinblastine, bleomycin, and methotrexate (VBM) 12 combined with extended-field radiotherapy (before 1997) or involved-field radiotherapy (after 1997); 126 patients with Stage I and II disease who had an unfavorable presentation because of lymphocyte-depleted histologic type or bulky mass or who had more than 1 factor among extranodal lesion, high ESR, and high LDH, were treated with 4 cycles of chemotherapy 13 with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by extended-field radiotherapy; 172 patients with Stage IIB, III, or IV disease were treated with 6 cycles of ABVD, or with alternating mechloretamine, vincristine, procarbazine, and prednisone (MOPP)/ABVD, 14 or with a hybrid schedule providing mechloretamine, vincristine, procarbazine, prednisone, epidoxorubicin, bleomycin, vinblastine, lomustine, melphalan, and vindesine (MOPPEB-VCAD). 15 In these patients with advanced-stage disease, radiotherapy was added optionally to the chemotherapy and was delivered only to lymphomatous lesions that responded slowly during chemotherapy or incompletely after the end of chemotherapy.…”
