Ninety-seven patients with aggressive malignant lymphoma (ML) were treated with an intensive and sequential chemotherapy (protocol LNH-80). There were 42 patients with intermediate grade ML, 53 patients with high-grade ML, and two patients with true histiocytic ML. Most of the patients were in advanced stage: 21 stage III and 61 stage IV. The LNH-80 protocol schedule comprised three phases: (1) induction with three courses of an intensified CHOP-Bleo (cyclophosphamide, doxorubicin, vindesine, methylprednisolone, and bleomycin); (2) consolidation with cytarabine, followed by high-dose methotrexate and folinic acid rescue, then asparaginase; and (3) final intensification with two courses of CVAP-Bleo (cyclophosphamide, teniposide, cytarabine, methylprednisolone, and bleomycin). CNS prophylaxis included one injection of methotrexate during each induction course and the drugs of the consolidation phase. In cases of initial CNS localization, cranial radiotherapy was added. Eighty-four patients (87%) went into complete remission (CR), 18 (21%) of whom relapsed, usually during the phase of treatment or within 6 months of completing chemotherapy. Sixty-three patients are alive with an overall median follow-up of 24 months. The median survival time and the median disease-free survival have not been reached, and the survival curve seems to have plateaued at above 60%. There was no statistical difference between intermediate-grade ML (CR 90%, relapse 18%) and high-grade ML (CR 84%, relapse 24%). The toxicity of this treatment is mainly encountered during the induction phase: almost all patients had short-term neutropenia, less than 0.500 g/L in 57, with a documented infection in 25. Overall treatment-related mortality was 6%, with four patients dying during the induction phase.

One hundred and forty-seven consecutive patients with previously untreated high-intermedium and high clinical risk diffuse large cell lymphoma (DLCL) were included in a prospective clinical trial to evaluate the efficacy and toxicity of escalating doses of epirubicin compared to standard doses in the CEOP-Bleo (cyclophosphamide, epirubicin, vincristine and prednisone and bleomycin) regimen, 55% of the patients were > 60 years old and most patients had adverse prognostic factors at diagnosis. Complete response rates were similar in both groups (68% in the standard dose compared to 73% in the escalating arm, (p = 0.5). However, time to treatment failure (TFF) and overall survival were better after escalating doses. At 3-years TTF at a medial follow-up of 33.6 months was 76% in the patients whose received escalating dose statistical different to 37% of the patients whose received standard doses (p < .01). Overall survival was 81% in the escalated therapy arm which is statistical different to 40% of the patients treated with standard doses (p < .01). Toxicity was mild in both arms. Neutropenia, mucositis and cardiotoxicity were mild in the escalated dose arm and no severe complications were observed. All patients received the planned doses of all drugs. Patients > 60 years old had the same CR rate, TTF and overall survival as younger patients. In conclusion it seems that the dose of epirubicin can be increased in combination chemotherapy regimens with safety and only mild toxicity. The CR rate was not superior compared to the standard dose but the TTF and overall survival were better. Longer follow-up periods are required in order to determine if the cure rate can also be improved. Older patients can also benefit because they also tolerated the increase in epirubicin without severe side effects and also improved their outcome. The use of more aggressive regimens with increase in dose intensity may be the treatment of choice for more patients poor prognosis, with DLCL provided there is no increase in toxicity. In this respect the use of epirubicin in higher doses/appears to be useful.

A retrospective study was performed to evaluate response rate, time to progression, and toxicity of a bleomycin and cytosine arabinoside (Bleo/Cytarabine) combination protocol for dogs with relapsed lymphoma (LSA). Dogs diagnosed with LSA and previously treated with chemotherapy were included in the study. A total of 20 dogs met the inclusion criteria, and 19 were evaluable for response. Bleomycin was administered subcutaneously on days 1 and 8 and cytosine arabinoside was administered subcutaneously on days 1-5 of a 21-day cycle. The median number of chemotherapy drugs given prior to the administration of Bleo/Cytarabine was 8.5. A total of 23 cycles of Bleo/Cytarabine were administered. The overall response rate was 36.8% (7 of 19 dogs had a partial response). The median time to progression was 15 days. Three dogs developed grade 3 thrombocytopenia and one dog had a grade 4 neutropenia. Bleo/Cytarabine had minor activity when used as a rescue therapy for pretreated LSA patients.
