Purpose: To evaluate the clinical features of presentation and the response to two different third-generation regimens (F-MACHOP and MACOP-B) of primary mediastinal large B-cell lymphoma (MLBCL), a recently defined distinct clinicopathological entity of non-Hodgkin's lymphoma (NHL). Patients and methods: Thirty-seven consecutive patients with MLBCL, eight male and 29 female (F/M ratio 1:3.5) with a median age of 35 years, were enrolled in the present study. Thirty-five (94.5%) patients presented disease confined to thorax, with chest symptoms of a rapidly enlarging mass in the mediastinum in 70% and superior vena cava syndrome (SCVS) in 43% of these patients. The first 10 patients received F-MACHOP and the succeeding 27 patients MACOP-B chemotherapy, associated in 24 (88.8%) with involved field radiation therapy (IFRT). Gallium scan was routinely performed pre- and post- IFRT in 18 patients. Results: All 37 patients were assessable for response: 10 of 10 (100%) in the F-MACHOP and 26 of 27 (96.3%) in the MACOP-B group achieved overall responses (CR+PR). Three of 24 (12.5%) patients in PR after chemotherapy obtained CR after IFRT. Persistent Gallium avidity was observed in 16 patients after chemotherapy and in only four patients after IFRT. Thus far, four of the 10 F-MACHOP and two of the 26 MACOP-B responders have presented disease progression. The probability of progression-free survival (PFS) was 91% and 60% (P <0.02) while overall survival (OS) was 93% and 70% (P = n.s.) at a mean follow-up of 27 and 52 months in the MACOP-B+IFRT and F-MACHOP groups, respectively. Conclusion: MACOP-B+IFRT has proved to be a highly effective and less toxic therapeutic approach for primary MLBCL and appears to be superior to other third-generation chemotherapy regimens.
