The role of "moderate-dose" systemic methotrexate in preventing central nervous system lymphomatous relapse is unknown. Certain patients with diffuse non-Hodgkin's histologic subtypes have an increased risk of relapse in the central nervous system, and it would be helpful to know if intravenous "moderate-dose" methotrexate might treat or possibly protect the meninges from involvement. In part, the rationale behind the recent regimen of methotrexate, bleomycin, doxorubicin (Adriamycin), cyclophosphamide, vincristine (Oncovin), and dexamethasone (m-BACOD) is to protect the central nervous system, and the empiric proof of this protection awaits the follow-up results of trials currently underway. In the meantime, the systemic and cerebrospinal fluid pharmacokinetics of moderate-dose intravenous methotrexate were studied in one patient whose histologic subtype places him at high risk for central nervous system involvement. Although the central nervous system levels of methotrexate in this patient never reached 1 X 10(-6) M, the levels exceeded 1 X 10(-7) M for at least 24 hours. The implications of peak dose versus sustained exposure to a lower dose of methotrexate are discussed.

The medical records of 396 consecutive patients with a histological diagnosis of Hodgkin's disease were reviewed to assess the prognostic importance of bulky and non-bulky lymphomas. The presence of large lymphadenopathy failed to affect significantly the seven-year results in terms of complete remission (bulky 81.1% v. non-bulky 86.2%), freedom from progression (60.7% v. 65.6%), relapse-free survival (75.1% v. 76.5%) and overall survival (62.7% v. 68.9%). It is noteworthy that in all subsets, ABVD (Adriamycin + bleomycin + vinblastine + dacarbazine), either combined with irradiation or alternated with MOPP (mechlorethamine + vincristine + procarbazine + prednisone), yielded superior results compared with MOPP with or without irradiation. Given the prognostic importance of various bulky sites, the presence of large lymphadenopathy in anatomic regions other than the mediastinum failed to affect results adversely. On the contrary, in patients in stages IIB-IIIA-IIIB, treated with combined modality, the presence of bulky mediastinal involvement did influence prognosis compared with patients with positive but non-bulky mediastinum. At seven years the results were 60.2% v. 79.9% for freedom from progression, 73.2% v. 89.9% for relapse-free survival and 64.8% v. 87.1% for total survival, respectively (P less than 0.03). By contrast, in patients with stage IV disease the extent of mediastinal involvement did not affect results. Nonetheless, the frequency of intrathoracic relapses was higher (26.7%) in patients given chemotherapy alone compared with patients treated with combined modality (11.5%).

In an attempt to reduce some of the delayed sequelae associated with combined modality therapy in Hodgkin's disease, we randomly tested stages IIB, IIIA, and IIIB MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) v ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine). In 232 previously untreated patients, three cycles of either combination preceded and followed extensive irradiation. The complete remission rate was 80.7% following MOPP and 92.4% following ABVD (P less than .02). The 7-year results indicated that ABVD was superior to MOPP in terms of freedom from progression (80.8% v 62.8%; P less than .002), relapse-free survival (87.7% v 77.2%; P = .06), and overall survival (77.4% v 67.9%; P = .03). Moreover, the comparative iatrogenic morbidity showed that irreversible gonadal dysfunction as well as acute leukemia occurred only in patients subjected to MOPP, while cardiopulmonary studies failed to document significant laboratory differences between the two treatment groups. Present findings indicate that ABVD followed by extensive irradiation represents a valid therapeutic alternative to the widely used alkylating agent-containing regimens plus radiotherapy.

Adriamycin is the most successful anthracycline in malignant lymphomas. Epirubicine is too new to be fully appreciated. Others anthracyclines have no real efficacy in nonleukemic lymphoid malignancies. The prognosis of malignant lymphomas has been transformed since the introduction of this drug in the chemotherapeutic protocols: the level of complete remission increased from 25% with CVP protocols to 50% with CHOP-types protocols, and to more than 70% with intensive chemotherapy protocols (m-BACOD, LNH-80). The number of live patients at 2 years grew in the same proportions. The efficacy of adriamycin in follicular lymphomas is of less value. In Hodgkin's disease the efficacy of adriamycin pull it to first line protocols (ABVD) with identical results to those obtained with MOPP chemotherapy. This drug has its place in the treatment of myeloma patients and in chronic lymphocytic leukemia patients with stage C.

From 1969 through 1982, 184 patients with advanced Hodgkin's disease (HD) were treated with combined modality therapy (CMT) at Yale University. The data were reanalyzed in November 1986, with a mean follow-up of 10 years. The patient population consisted of 102 newly diagnosed stages IIIB and IV patients, and 82 patients who had relapsed after initial radical radiotherapy. From 1969 through 1978, the treatment program was induction chemotherapy with nitrogen mustard, vincristine, vinblastine, procarbazine, and prednisone (MVVPP) for three cycles (6 months) followed by low-dose radiation (1,500 to 2,500 cGy) for patients who had achieved complete remission (CR), to all disease sites present before the onset of chemotherapy. From 1978 to 1982, selected "poor-risk" advanced-stage patients received nitrogen mustard, vincristine, procarbazine, prednisone plus Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), bleomycin, vinblastine, and dacarbazine (MOPP-ABVD) induction chemotherapy, while the remaining patients were randomized between MVVPP and MOPP. One hundred fifty-one patients have achieved CR (82%); 23 (15%) of these 151 have relapsed, with the remaining 128 patients in continuous CR. A total of 62 patients have died, 45 due to HD, and 17 due to other causes. Twelve of these 17 patients died of second malignancies. The 15-year actuarial survival of all patients is 54%. It is 71% if deaths due only to HD are considered. Within the overall group of advanced HD patients, age and multiple extranodal sites of involvement continue to constitute adverse risk factors. The three drug programs used were all equivalent. No improvement resulted from the use of MOPP-ABVD in the poor-risk patients. These results compare favorably with those recently published by the National Cancer Institute (NCI). CMT resulted in an approximate 20% improvement in survival with no increase in second malignancies when compared with chemotherapy alone.

Results of treatment of 25 Hodgkin's disease patients at Kyushu University Hospital from 1981 to 1985 were reviewed. Total nodal irradiation or MOPP chemotherapy was used mainly. The actuarial 5-year survival rate, 87.2%, was significantly better than the 41.0% of 61 patients treated between 1966 and 1980 (P less than 0.01). However, 12 of the 24 patients in remission eventually relapsed. To further improve the survival rates of patients with Hodgkin's disease, technical improvements in total nodal irradiation and altering Adriamycin-containing chemotherapy protocol from MOPP chemotherapy are advisable.

This paper reports the 5-year results of a prospective randomized study beginning in 1976 on 177 evaluable patients with pathologic Stage I-IE and II-IIE non-Hodgkin's lymphomas with diffuse histology according to the Rappaport classification. Treatment consisted of either CVP or BACOP chemotherapy (3 cycles) followed by regional radiotherapy (40 to 50 Gy) and further cycles of either combination. In both arms, complete remission at the end of combined treatment was high (CVP 93%, BACOP 98%) regardless of age, stage or bulky disease. At 5 years, the comparative freedom from first progression was 62% for CVP vs 78% for BACOP (p = 0.02), respectively. Clinically relevant differences favoring BACOP chemotherapy were essentially documented in patients with large cell lymphomas (International Working Formulation), those with Stage II having more than three involved anatomical sites, bulky disease and age over 60 years. Recurrence within radiation fields was documented in only 5% of complete responders. Combined treatment was, in general, well tolerated particularly when BACOP was used. In only 2 patients given CVP post radiation cutaneous fibrosis was documented. Second solid tumors were detected in 4 patients. One patient started on CVP died because of brain stem necrosis after 45 Gy. We conclude that in Stage I-II patients with nodal and extranodal diffuse non-Hodgkin's lymphomas, particularly large cell lymphomas, combined modality approach with primary Adriamycin and bleomycin containing regimen, such as BACOP, followed by adjuvant radiotherapy offers high chances of cure with minimal toxicity.

Seventeen patients with advanced stage Hodgkin's disease who relapsed or failed to respond to multiple regimens of combination chemotherapy (mostly Mechlorethamine, Vincristine, Procarbarzine, Prednisone and Adriamycin, Bleomycin, Vinblastine, Dacarbazine) were treated with accelerated hyperfractionated total lymphoid irradiation (TLI) and high-dose chemotherapy followed by autologous bone marrow transplantation (AuBMT). Candidates for the protocol did not have prior radiation therapy and had no evidence of bone marrow involvement. Their bone marrow was initially harvested and cryopreserved. The treatment protocol consisted of reinduction with conventional doses of combination chemotherapy followed by boost local field irradiation to areas of residual disease (1500 cGy within 5 days) and total lymphoid irradiation (2004 cGy given in 12 fractions of 167 cGy each t.i.d. delivered within 4 days). The patients were treated with Etoposide (250 mg/m2/day I.V. X 3 days) and high-dose Cyclophosphamide (60 mg/kg/day I.V. X 2 days). Cryopreserved (unpurged) autologous bone marrow was infused 48 hr after completion of chemotherapy. Of the 17 patients treated, four were in relapse and 13 refractory to multiple regimens of combination chemotherapy. Four patients died during the immediate peritransplant period (2--septicemia, 2--pulmonary complications). Of the 13 surviving patients, 12 entered a complete remission and one had a partial remission and died of disease 6 months later. One patient relapsed 5 months after treatment and is currently alive with disease. Eleven patients (65%) are alive with no evidence of disease 4-35 months (median 20 months) following completion of therapy. Treatment with this protocol results in a high rate of complete remission and a potential for long-term disease-free survival in previously unirradiated patients with advanced stage refractory or relapsed Hodgkin's disease who have exhausted conventional modes of chemotherapy.

31 patients with intermediate and high-grade non-Hodgkin lymphomas were treated by a six-drug alternating regime comprising four cycles of 200 mg/m2 i.v. methotrexate on days 8, 15, 28 and 35, 50 mg/m2 i.v. Adriamycin on day 1, 40 mg/m2 oral prednisolone on days 1-7 and 21-27, 120 mg/m2 i.v. etoposide on days 21-23, 600 mg/m2 i.v. cyclophosphamide on day 21 and 1.4 mg/m2 i.v. vincristine on day 1 (MAPECO). In all, 3 patients had stage I disease, 12 stage II, 6 stage III and 10 stage IV. Of 28 evaluable patients, 19 were complete responders (68%) and 9 were partial responders (32%); at 2 years, the actuarial relapse-free survival of the 19 patients achieving complete remission is 80%, and 5 patients remain in complete remission at 3 years. This is a preliminary report of an effective intensive regime with acceptable toxicity.

Doxorubicin (adriamycin) has a very wide antitumour spectrum, compared with other anticancer drugs; however, except for Hodgkin's disease, it is not associated with curative chemotherapy. Doxorubicin has been in clinical use for more than 2 decades, and only recently has it been recognised that the cytotoxic effect is produced at the cellular level by multiple mechanisms which have not yet been conclusively identified. Key factors are a combination of doxorubicin-induced free radical formation due to metabolic activation, deleterious actions at the level of the membrane, and drug-intercalation into DNA. Multiple aspects of the clinical pharmacokinetics of this drug have been described. Wide interpatient variations in plasma pharmacokinetics have been noted, but without firm relation to clinical outcome. An apparent volume of distribution of approximately 25 L/kg points to extensive uptake by tissues. Up to several weeks after administration, significant concentrations of doxorubicin have been found in haematopoietic cells and in several other tissues. The maximum cellular doxorubicin concentrations reached in vivo remain significantly below those at which all clonogenic leukaemic cells are killed in vitro. Doxorubicin has been administered as frequent (weekly) low doses, single high doses, and as a continuous infusion. The optimal schedule with respect to tumour cytotoxicity and dose-limiting side effects such as myelosuppression or cardiotoxicity, has never been investigated in a prospective, randomised manner. Clinical trials large enough to study optimal, and possibly individualised, doxorubicin chemotherapy need to be performed. This review summarises pharmacological and pharmacodynamic data of doxorubicin, and discusses these in relation to possible improvement of its therapeutic index. Furthermore, drug interactions, dose-response relationships, mechanisms of action, multidrug resistance, and treatment scheduling are discussed in the perspective of the development of novel treatment strategies.
