We performed a controlled clinical trial to define the use of a brief therapy: CMED (cyclophosphamide, etoposide, methotrexate, and dexamethasone) compared with standard CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) in the treatment of peripheral T-cell lymphoma unspecific (PTCLu). The end point to the study was to assess efficacy, measured from complete response rate (CRR), progression-free survival (PFS), and overall survival in 217 previously untreated patients with PTCLu. In an intent-to treat analysis all patients were evaluable.

One hundred and ninety-six patients were randomized to received CEOP-rituximab (cyclophosphamide 1500 mg/m2, epirubicin 120 mg/m2, vincristine, and prednisone at standard dose and rituximab at 375 mg/m2) compared with the same chemotherapy administered every 14 d (CEOP-14). In an intent-to-treat analysis all patients were available for efficacy and toxicity.

Radiotherapy has been used in some retrospective studies without definitive conclusions. We report the first controlled clinical trial to define the role of radiotherapy in this setting of patients.

Younger patients (defined as a cut-off level < 65 years old) will be treated with chemotherapy and transplant procedures. However, most patients > 65 years old are not candidates for this therapeutic approach and the use of intensive chemotherapy could be associated to severe toxicity.

Apparently, cardiac toxicity is more frequent after 10 years of anthracycline therapy, but no longer studies of cardiac toxicity have been reported. Four hundred and seventy-six patients with Hodgkin's disease, stages III and IV, were randomly assigned to receive ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) compared with EBVD (epirubicin instead of doxorubicin) and MBVD (mitoxantrone instead of doxorubicin) at standard doses.

We began a controlled clinical trial to evaluate efficacy and toxicity of the most common therapies. Two hundred and forty-one patients with gastric low-grade MALT lymphoma in early stage (IE and IIE) were randomized to surgery (80 cases), radiotherapy (78 cases), and chemotherapy (83 cases).

One hundred previously untreated patients were treated with an intensive CEOP-Bleo regimen with increased doses of cyclophosphamide (1000 mg/m(2)) and epirubicin (120 mg/m(2)) in each cycle. Granulocyte colony-stimulating factors was employed to ameliorate severe granulocytopenia.

We began a prospective controlled clinical trial to evaluate impact in event free survival (EFS) and overall survival (OS) in a large cohort of patients with a longer follow-up. Between 1989 and 1995; 341 patients with aggressive DLCL and presence of nodal bulky disease (tumor mass > 10 cm) in pathological proven complete response after intensive chemotherapy were randomized to received either radiotherapy (involved fields, 40 Gy) or not.

We conducted a controlled clinical trial to evaluate the efficacy and toxicity of interferon-alpha 2b, cyclophosphamide, and prednisone as maintenance therapy in patients with aggressive diffuse large B cell lymphomas in complete remission after aggressive chemotherapy. In an intent-to-treat analysis, 169 patients were eligible for this study; the end points were event-free survival (EFS) and overall survival (OS).

Two hundred and sixty four patients were randomized to receive EBVD chemotherapy (134 cases) or intensive chemotherapy (130 cases). Eligible patients were either previously untreated stages III or IV.

Material And Methods: Between 1981 and 1995, patients with follicular lymphoma were treated with combined chemotherapy, mostly anthracycline-based regimens; patients who achieved complete response were randomly assigned either to receive adjuvant radiotherapy to sites or to nodal bulky disease or not (control group).
Results: Four hundred and sixty-nine patients were randomized; in an intent-to-treat analysis all were evaluable for efficacy and toxicity.
Anthracyclines remain as the best drugs in the treatment of patients with aggressive malignant lymphoma in combination with other cytotoxic drugs. However, dose escalation is poorly tolerated and acute and late cardiac toxicity has limited the use of these compounds. Pegylated liposomal doxorubicin has been proven to be useful in some malignancies, without the presence of acute cardiac toxicity and with a good response rate in patients with relapsed/refractory lymphomas.

Forty-eight patients with SCC as unique manifestation (IE) of malignant lymphoma, were randomly assigned to receive either: radiotherapy (16 patients), chemotherapy (11 patients) or combined therapy (radiotherapy followed by chemotherapy, 21 patients). Although neurological recovery was similar in both groups, EFS and OS were better in the combined therapy arm.

Patients previously untreated with pathologically documented advanced stages Hodgkin's disease were randomly assigned to received chemotherapy alone with EBVD regimen (epirubicin, bleomycin, vinblastine and dacarbazine): 56 patients or combined therapy: The same chemotherapy regimen following by adjuvant radiotherapy (35 Gy) to sites of initial bulky disease (tumor mass >7 cm diamenter): 54 patients. Five year overall survival rates were 88% (48 patients) and 60% (34 patients) from combined therapy compared to chemotherapy alone respectively (p < 01) (95% confidence interval (CI): for the difference 18% to 39%).
