Between 1980 and 1982, 162 patients with non-Hodgkin's lymphoma were treated with cyclophosphamide, adriamycin, vincristine and prednisone (CHOP) or CHOP plus bleomycin. At the moment when the patient were diagnosed all clinical characteristics were evaluated according to a multiple regression analysis model, which has the following three factors associated to bad prognosis: a quick clinical evolution (less than three months) bone marrow infiltration and high levels of lactate dehydrogenase (LDH). The Cox model of analysis also agreed that a quick clinical evolution and the high levels of LDH were bad prognosis factors. These two factors were associated with poor complete remission and short survival rates. A mathematical model was built based on the last two factors. Five groups of patients were observed with increasing risk of a poor response and a short survival rates, which allowed us to identified three prognostic groups with clear differences in both the duration of remission and survival. These groups were low, moderate and high-risk. Results analysis in this paper have important clinical implications for the design of the prospective clinical trials in patients with malignant lymphoma.

Curative combination chemotherapy is available for many patients with aggressive non-Hodgkin's lymphoma (NHL); however, treatment of elderly patients with these regimens is difficult due to excessive toxicity. From 1983 to 1988 the authors treated 26 patients 65 years and older with aggressive NHL with a novel 8-week chemotherapy regimen containing bleomycin, etoposide, cyclophosphamide, doxorubicin, methotrexate with leucovorin, and prednisone (BECALM), designed to preserve dose intensity and minimize toxicity. Median age was 75 years. Histologic types included the following: 20 intermediate grade (16 large noncleaved cell; two large cleaved cell; one intermediate grade, unspecified); six high grade (four small noncleaved cell; one immunoblastic sarcoma B-cell; one high grade, unspecified). Twenty-one patients were Stage III or IV. Twenty-two of 26 patients had one or more of the following: tumor greater than 10 cm; multiple extranodal sites; lactate dehydrogenase (LDH) 400 IU/l or greater; small noncleaved cell histologic type. Chemotherapy consisted of bleomycin 20 U intravenously (IV) weeks 1 and 7; etoposide 75 mg/m2 IV every day x 3 days on week 4; cyclophosphamide 600 mg/m2 IV weeks 1, 4, 7; doxorubicin 40 mg/m2 IV weeks 1, 7; methotrexate 50 mg/m2 IV weeks 1, 2, 4, 5, 7, 8 with oral leucovorin rescue; prednisone 60 mg orally for 10 days on weeks 1, 4, 7. Eighteen patients completed the 8-week treatment course. There were 13 complete responses (CR); seven patients remain in continuous CR at a median follow-up of 37.5 months. There have been five relapses, including one late relapse; and one patient died of an intercurrent illness in CR. Overall and actual event-free survivals are 38% and 27%, respectively. The major toxicities were neutropenic fever and mucositis. There were four treatment-related deaths. The authors conclude that BECALM chemotherapy can be administered to elderly patients with aggressive NHL. Although neurotoxicity and cumulative toxicity from bleomycin and anthracycline are avoided, the regimen remains moderately toxic, particularly with respect to myelosuppression. Treatment results compare favorably with other reported regimens in this group of patients with multiple poor prognostic features.

A total of 92 patients with previously untreated intermediate- or high-grade non-Hodgkin's lymphoma attending the University Department of Medicine, Queen Mary Hospital, Hong Kong, were treated with the m-BACOD chemotherapy regimen (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine and dexamethasone). Additional involved-field radiotherapy was given to 32 (35%) patients. Myelosuppression was the major toxicity, and 5 (5%) treatment-related deaths occurred due to pneumonia, bleomycin sensitivity, doxorubicin cardiotoxicity and reactivation of hepatitis B infection. The overall complete response (CR) rate was 65/92 (71%) and the relapse rate was 22/65 (34%). The disease-free survival of the 65 CR patients at 2 years was 52% and the overall survival of all 92 patients at 3 years was 56%. The CR rate of stage I and II patients was significantly better than that of those with stage III and IV disease (87% vs 59%; P = 0.01), and the CR rate of stage III patients was superior to that of those with stage IV disease (86% vs 50%; P = 0.05). The overall survival of stage III and IV patients was significantly worse than that of subjects with stage I and II disease (31% vs 73%; P = 0.02). Multivariate analysis revealed that the independent prognostic variables significantly determining the CR rate and survival included the clinical stage and the serum lactate dehydrogenase level. From this study, the results of treatment with the m-BACOD regimen in patients with advance disease appeared to be similar to those obtained using the conventional CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone).

Acute renal failure is rarely the presenting manifestation of non-Hodgkin's lymphoma. Of the reported cases of renal insufficiency secondary to diffuse renal infiltration with lymphoma, few have presented with acute renal failure. We present a patient with acute renal failure secondary to diffuse bilateral renal infiltration by a B-cell non-Hodgkin's lymphoma. The findings of an elevated serum lactate dehydrogenase (LDH), lymphopenia, and homogenous bilateral renal enlargement on computed tomographic (CT) imaging were important in suggesting the diagnosis of primary renal lymphoma. Renal biopsy with immunohistochemical and ultrastructural analysis was instrumental in confirming this diagnosis.

Forty-five previously untreated patients with intermediate or high-grade non-Hodgkin's lymphoma were treated with the Pro-MACE-C-MOPP regimen (flexitherapy). The median age of the patients was 51 years, 51% had constitutional symptoms, 78% were in Ann Arbor stage III-IV, 40% had two or more involved extranodal sites and 87% had serum lactate dehydrogenase (LDH) above 225 U/l. Twenty-two (49%) patients had immunoblastic lymphoma (Working Formulation). Overall, 40% of the patients attained complete response (CR) and there were no relapses. The dose-limiting toxicity was myelosuppression (69% of the patients with WBC less than 1.9 x 10(9)/l). Three deaths were attributed primarily to chemotherapy, but another two patients died of long-term complications of therapy. After a median follow-up of 50 months (18-80), 15 patients (33%) were alive without lymphoma. Only histologic subtype (intermediate vs. high) and abdominal involvement were prognostic factors for CR rate. Our results indicate that ProMACE-C-MOPP is an effective regimen for intermediate-grade lymphomas. However, in high-risk patients the regimen seems to be less effective than originally reported.

The clinical studies about the electrolyte abnormality (EA) in patients with malignant lymphoma (ML) are rarely reported. We analyzed the EA and renal insufficiency in 123 patients with ML between June. 1976 and Jan. 1989; 8 patients with Hodgkin's disease, and 115 patients with non-Hodgkin's lymphoma (NHL). Before treatment, the incidence of the EA was 24.2% and hypercalcemia, hypocalcemia, and hyperkalemia were predominant. After treatment it became to 74.7% and the number of hyponatremia and hypokalemia increased. The incidence of proteinuria and renal insufficiency (serum creatinine above 1.5 mg/dl), were 7.3% and 2.4% before treatment, and became to 26.8% and 26.8% after treatment, respectively. There was a significant difference between two groups with and without the EA before treatment as for serum lactate dehydrogenase (LDH) levels (p less than 0.01), clinical stages (p less than 0.05) and the incidence of bone marrow involvement (p less than 0.01). In 34 autopsied cases, 3 cases showed massive renal involvement and about a half of cases showed various renal changes. The EA before treatment was caused by extrarenal factors, because the incidence of proteinuria and renal insufficiency were almost same to healthy controls. And renal factors play an important role on the E.A after treatment. Above results suggest that the EA before treatment indicates the progress of malignant lymphoma and the EA after treatment means not only the progress of the disease but also therapy-related renal damages.

From October 1977 through September 1986, a total of 77 patients (Stage I, 26; II, 35; and III-IV, 16) with primary non-Hodgkin's lymphoma (NHL) of the head and neck were treated with radiation therapy and chemotherapy (CVP or CHOP regimen) or radiation therapy alone. Actuarial 5-year survival rates by stage were 79% in Stage I, 35% in II, and 8% in III-IV. Significant prognostic factors were clinical stage (p = 0.0001), histological grade by the Working Formulation (p = 0.0089), and surface marker (T and B cell analysis) (p = 0.0001). In Stage II patients, the serum lactate dehydrogenase (LDH) level (p = 0.0286), the number of cervical lymph nodes involved (p less than 0.03), and maintenance chemotherapy after initial treatment (p = 0.0077) were significant prognostic factors. In conclusion, more intensive chemoradiotherapy is necessary as the first-line treatment in those with poor prognosis, especially those with T-cell type and high grade histology. In addition, maintenance chemotherapy after initial chemoradiotherapy is very important for Stage II NHL patients, especially those with a high LDH value or multiple cervical lymph node involvement.

Forty-seven previously untreated patients with intermediate- or high-grade non-Hodgkin's lymphoma were treated with four courses of a regimen that consisted of high-dose (120 mg/m2) Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), vincristine (2 mg), cytarabine (3 gm/m2), and dexamethasone (50 mg intravenously [IV] on day 1 and 20 mg/day orally on days 2 to 5) (AVAD), which was administered every 3 to 4 weeks. The median age of the patients was 58 years; 72% were Ann Arbor stage IV, 49% had "B" symptoms, 62% had masses larger than 7 cm, 40% had masses at least 10 cm in diameter, and 49% had serum lactate dehydrogenase (LDH) greater than 250 U/L. Overall, 72% of the patients (89% of diffuse large-cell lymphoma [DLCL] patients) attained complete (CR) or probable complete responses (PCR), and relapses occurred in 32%. There were no episodes of clinical congestive heart failure, but one patient developed recurrent ventricular arrhythmias. Fever during neutropenia occurred with 65% of treatment courses. Three deaths were attributed primarily to complications of therapy. The lymphoma-free survival of all entered patients is 51% (24 of 47), with a follow-up of 30 to 67 months (median, 58 months). These results confirm that high CR/PCR and long-term survival rates can be achieved in patients with aggressive histologies of non-Hodgkin's lymphomas, even in groups with poor prognostic factors, using high-dose anthracycline-containing chemotherapy regimens delivered over a short period of time. However, the apparently higher relapse rate in comparison to our previous study leads us to speculate that consolidation with noncross-resistant agents may be helpful in increasing even further the cure rate in this group of patients.

We describe the chromosomal abnormalities found in 104 previously untreated patients with non-Hodgkin's lymphoma (NHL) and the correlations of these abnormalities with disease characteristics. The cytogenetic method used was a 24- to 48-hour culture, followed by G-banding. Several significant associations were discovered. A trisomy 3 was correlated with high-grade NHL. In the patients with an immunoblastic NHL, an abnormal chromosome no. 3 or 6 was found significantly more frequently. As previously described, a t(14;18) was significantly correlated with a follicular growth pattern. Abnormalities on chromosome no. 17 were correlated with a diffuse histology and a shorter survival. A shorter survival was also correlated with a +5, +6, +18, all abnormalities on chromosome no. 5, or involvement of breakpoint 14q11-12. In a multivariate analysis, these chromosomal abnormalities appeared to be independent prognostic factors and correlated with survival more strongly than any traditional prognostic variable. Patients with a t(11;14)(q13;q32) had an elevated lactate dehydrogenase (LDH). Skin infiltration was correlated with abnormalities on 2p. Abnormalities involving breakpoints 6q11-16 were correlated with B symptoms. Patients with abnormalities involving breakpoints 3q21-25 and 13q21-24 had more frequent bulky disease. The correlations of certain clinical findings with specific chromosomal abnormalities might help unveil the pathogenetic mechanisms of NHL and tailor treatment regimens.

Four patients with warm type autoimmune hemolytic anemia who failed to respond to steroid therapy received high dose intravenous gammaglobulin (0.2-0.4 g/kg daily) for five days. In one patient hemolysis occurred in association with non-Hodgkin's lymphoma and in the others the cause of the hemolysis was not established; two patients had prior splenectomy. A response to gammaglobulin therapy, demonstrable by a rise in or stabilisation of hemoglobin levels, a decrease in elevated serum bilirubin and lactate dehydrogenase levels, or prolongation of a shortened red cell (51Cr) survival, was observed in three patients. In two of these patients the effect of gammaglobulin therapy was temporary but allowed for splenectomy to proceed in one patient, without blood transfusion. The third patient continued to improve after cessation of gammaglobulin treatment. These findings suggest that high dose intravenous gammaglobulin may temporarily ameliorate hemolysis in some individuals with warm type immune hemolytic anemia, and may be a useful adjunct to steroids immediately before splenectomy.
