Forty-nine previously untreated adult patients with diffuse non-Hodgkin's lymphoma were treated with MACOP-B (methotrexate, adriamycin, cyclophosphamide, vincristine, prednisolone and bleomycin) between December 1986 and December 1990. Forty patients (82%) achieved a complete response (CR), three (6%) a partial response (PR), while four (8%) had either no response or progression of disease, one (2%) patient ceased MACOP-B therapy and received other chemotherapy because of sustained neutropenia, and one patient (2%) died of sepsis during therapy. The factors that adversely affected the CR rate were by stage IV, the presence of B symptoms, the presence of a large mass (greater than 5 cm), and low serum total protein level. The 4-year survival for all 49 patients was 70% and the 4-year disease-free survival (DFS) for the 40 CR patients was 77%. Relapses were higher in patients whose initial serum lactic dehydrogenase (LDH) level was higher than 660 IU/1 (DSF 89% vs. 49%). Toxicity was substantial but acceptable, with neutropenia and mucositis proving to be the most frequent severe side-effects. These preliminary results confirmed the effectiveness of MACOP-B therapy for diffuse non-Hodgkin's lymphoma.

We carried out a study in patients with severe neutropenia from hematologic malignancy and suspected gram-negative sepsis to evaluate the clinical significance of endotoxin concentrations in plasma before and during a therapeutic intervention with a human polyclonal immunoglobulin M (IgM)-enriched immunoglobulin preparation (Pentaglobin; Biotest, Dreieich, Germany). Twenty-one patients with acute leukemia or non-Hodgkin's lymphoma entered the study upon the development of clinical signs of gram-negative sepsis and received the IgM-enriched immunoglobulin preparation every 6 h for 3 days (total dose, 1.3 liter with 7.8 g of IgM, 7.8 g of IgA, and 49.4 g of IgG), in addition to standardized antibiotic treatment. Concentrations of endotoxin and IgM and IgG antibodies against lipid A and Re lipopolysaccharide (LPS) in plasma were determined by a modified chromogenic Limulus amebocyte lysate test and semiquantitative enzyme linked immunosorbent assay, respectively, before each immunoglobulin infusion and during the following 25 days. Seventeen patients were endotoxin positive; in five of these patients, gram-negative infection was confirmed by microbiologic findings. Prior to therapy, endotoxemia correlated significantly with the occurrence of fever, and a quantitative correlation between the endotoxin concentration and body temperature was found during the individual course of infection in 8 of the 17 patients. Overall mortality from endotoxin-positive sepsis was 41% (7 of 17) and 64% (7 of 11) in patients with symptoms of septic shock. Nonsurvivors had significantly higher maximum concentration of endotoxin in plasma compared with those of survivors at the first study day (median of 126 versus 34 pg/ml; P < 0.05) and during the whole septic episode (median of 126 versus 61 pg/ml; P < 0.05). In survivors, immunoglobulin therapy resulted in a significant decrease in endotoxin levels in plasma within the initial 18-h treatment period, from a pretreatment median value of 28 pg/ml to a value of 8 pg/ml (P< 0.05). In the seven patients who died from uncontrollable infection, no effect of therapy on endotoxin levels in plasma was observed. IgM and IgG antibodies against lipid A and Re LPS increased significantly under immunoglobulin treatment, with significant correlations between antibodies against lipid A and Re LPS. These data strongly suggest a prognostic significance of the endotoxin levels in plasma and a potential effect of treatment with a polyclonal IgM-enriched immunoglobulin preparation. Further studies are needed to substantiate these findings and to assess the impact on the clinical course by way of a prospective placebo-controlled clinical trial.

In a prospective study, we analysed the anorectal lesions observed in 148 human immunodeficiency virus-infected patients and compared the data with those reported in the literature. The majority of the patients (97.3%) were homosexual or bisexual men. The mean age of the population was 34.2 years. A history of previous sexually transmitted diseases was found in 79.7% of the male patients. The stage of HIV-related disease, according to the Centers for Disease Control classification, could be determined in 141 patients: 54.6% were stage II, 3.5% stage III and 41.8% stage IV. Anal condylomata were the most frequent manifestation, affecting 29.7% of the patients, 7.1% of whom showed moderate to severe dysplasia. The types were mainly 6, 11, 16 and 18, but types 31, 35 and 39 were also observed. Ulcerations were the most frequent non-condylomatous lesions, occurring in 41 patients; most (60%) were due to herpes viruses, and a large minority (21%) to cytomegalovirus. The etiology could not be determined in five cases. Anal sepsis was present in 11.4%, haemorrhoidal disease in 16.8% and fissures in 6%. Six patients developed Kaposi's sarcoma and seven, non-Hodgkin's lymphoma. No anal cancers were observed. Finally, wound healing was slowed in the patients operated on for haemorrhoids, fissures and suppuration. No statistical analysis could be performed because of the small number of patients.

A case is described of an HIV+ man who was successfully treated for Hodgkin's lymphoma, but who later developed non-Hodgkin's lymphoma 3 years later when his immune system became suppressed. The patient was 22 years old when he presented with fever, asthenia, weight loss, and cervical lymphadenopathy. With Hodgkin's lymphoma he also had positive serology for HIV and hepatitis B. He was treated with alternate courses of MOPP and ABVD chemotherapy. In 1990 he again appeared with high fever, progressive cervical, axillary and inguinal lymphadenopathy, with hilar and mediastinal lymph node enlargement on x-ray. CD4 lymphocytes were 577/cubic mm, and the CD4/CD8 ratio was 0.57 (normal 1.8). His cervical lymph node biopsy was classified as non-B non-T large-cell anaplastic lymphoma which was EBV-positive. A Western Blot was positive for small amounts of p24 and p18 antigens. The man was treated with MACOP-B chemotherapy, with some results, but died of sepsis 6 weeks later. The relationships between Hodgkins and non-Hodgkin's lymphoma, the timing of the neoplasm in the course of HIV infection, and the possible re-activation of hepatitis virus were discussed.

Sixty-two patients with advanced-stage Hodgkin's disease and a median age of 12 years (range, 3 to 22 years) were treated with four cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) alternating with four cycles of doxorubicin, vinblastine, bleomycin, and dacarbazine (ABVD) followed by low-dose radiotherapy (RT). We determined the feasibility, immediate safety, and rapidity of response of patients to this regimen, as well as the relationship between prognostic factors and the rate of complete remission (CR), event-free survival (EFS), and overall survival. Therapy was well tolerated, and the major toxicity was hematopoietic. At the end of chemotherapy, 54 of 62 patients (87%) were in CR by clinical restaging, with a biopsy of residual disease where necessary. The actuarial 3-year EFS is 77% (SE, 11%), with a median follow-up of 35 months, and the survival is 91% (SE, 7%). With respect to EFS, female patients and those with stage II or III disease fared statistically better than males and patients with stage IV disease, respectively. Six patients have died: three of progressive Hodgkin's disease, one of secondary acute myelocytic leukemia (AML), one of secondary non-Hodgkin's lymphoma (NHL), and one of overwhelming bacterial sepsis. The Pediatric Oncology Group (POG) is currently engaged in a randomized study of these eight cycles of chemotherapy with and without RT to assess the role of RT in achieving comparable results.

High response and overall survival rates have been reported for second- and third-generation combination chemotherapy regimens used in the treatment of advanced intermediate- and high-grade non-Hodgkin's lymphoma (NHL). Results with methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOP-B) chemotherapy have been particularly impressive, although this regimen produces considerable toxicity. We have devised a similar regimen, which differs from previously reported weekly regimens in that it includes etoposide given at 14-day intervals. The doses of methotrexate and prednisolone were lower in our regimen than those used in MACOP-B. Alternating cycles of cyclophosphamide, doxorubicin, and etoposide (week 1) and methotrexate, bleomycin, and vincristine (week 2) were given for a total of 12 weeks, with continuous oral prednisolone and prophylactic antibiotics. We report here the first 61 patients entered onto this study. The overall response rate is 84% (57% complete remission [CR], 27% partial remission [PR]). With a median follow-up of 32 months for surviving patients, the actuarial overall survival at 3 years is 47%, and the failure-free survival is 45%. The dose-limiting toxicity of this regimen was mucositis. Five deaths occurred during chemotherapy, two of which were due to sepsis. The dose intensities of cyclophosphamide and doxorubicin in this regimen are considerably lower than those in MACOP-B. However, because of the inclusion of etoposide, the projected average relative dose intensity for our regimen is higher than that for MACOP-B. Our regimen has produced inferior results to those reported for MACOP-B. This may be because the addition of etoposide has failed to compensate for the lower doses of doxorubicin and cyclophosphamide. Alternatively, it may reflect differences in the presenting features of the patient populations.

Forty patients with refractory solid tumors or non-Hodgkin's lymphoma were treated with high-dose cyclophosphamide, thiotepa, and carmustine (BCNU), followed by autologous stem cell rescue, in a phase I dose escalation study. The dose-limiting toxic effect was delayed drug-induced pulmonary disease, seen in three patients who received 660-750 mg of BCNU/m2 in combination with cyclophosphamide and thiotepa. The early death rate due to toxic effects was 20%; all deaths were attributed to sepsis or respiratory failure. The overall response rate was 63%. The median time to disease progression was 14 weeks. Although this regimen provided effective cytoreduction, its use in heavily pretreated patients with bulky disease is of limited value.

Patients with the acquired immune deficiency syndrome (AIDS) frequently develop hepatic dysfunction. Although hepatic injury may indirectly result from malnutrition, hypotension, administered medications, sepsis, or other conditions, the hepatic injury is frequently due to opportunistic hepatic infection, directly related to AIDS. Infection with Mycobacterium avium intracellulare typically occurs in patients with advanced immunocompromise and with systemic symptoms due to widely disseminated infection. In contrast, hepatic tuberculosis often occurs with less advanced immunocompromise. Cytomegaloviral infection may produce a hepatitis. Cytomegaloviral and cryptosporidial infections have been implicated as causes of acalculous cholecystitis and of a secondary sclerosing cholangitis. About 10-20% of patients with AIDS have chronic hepatitis B infection. These patients tend to develop minimal hepatic inflammation and necrosis. The clinical findings in patients with hepatic cryptococcal infection are usually due to concomitant extrahepatic infection. Hepatic histoplasmosis usually develops as part of a widely disseminated infection with systemic symptoms. Hepatic involvement by Kaposi's sarcoma is rarely documented ante mortem because an unguided liver biopsy is an insensitive diagnostic procedure. Patients with non-Hodgkin's lymphoma of the liver typically have lymphadenopathy, hepatomegaly, and systemic symptoms. As a pragmatic approach, patients with liver dysfunction and HIV-related disease should have a sonographic or computerized tomographic examination of the liver. Patients with dilated bile ducts should undergo endoscopic retrograde cholangiopancreatography because opportunistic infection may produce biliary obstruction. Patients with a focal hepatic lesion should be considered for a guided liver biopsy. Patients with a significantly elevated serum alkaline phosphatase level should be considered for a percutaneous liver biopsy. When performed for these indications, liver biopsy will demonstrate a significant disease involving the liver in about 50% of patients with AIDS and in about 25% of patients who are HIV seropositive but who are not known to have AIDS. The clinical impact of a diagnostic biopsy is blunted by a lack of efficacious therapy for many opportunistic infections.

Twenty-two patients with refractory intermediate- or high-grade non-Hodgkin's lymphoma were treated with dexamethasone 10 mg every six hours and ifosfamide 1 g/m2, cisplatin 25 mg/m2, etoposide 100 mg/m2 (DICE), and mesna uroprotection daily x4 every 3 to 4 weeks. Pretreatment with prochlorperazine and metoclopramide was given to prevent nausea and vomiting. Eighteen men and four women, aged 21 to 74 years (median age, 65) have received a total of 64 cycles. Seventeen patients had stage IV, one had stage III, and four patients had stage II disease. Seven patients had B symptoms and 11 had marrow involvement. Only two patients had had more than one previous chemotherapy regimen. Median time from last chemotherapy to DICE was 7 months (range 1 to 41). Two patients who suffered early treatment-related deaths (from sepsis) were classified as nonresponders. Six of 22 patients (27%) achieved complete remission (2 to 22+ months), and 11 (50%) had partial remissions (1 to 8+ months) for an overall response rate of 77%. Median survival has not been reached yet, and 12 patients are alive 1 to 22 months from the start of treatment. Nine patients had nadir granulocyte counts less than 0.5 x 10(9)/L; six required RBC transfusions and five, platelet transfusions. The platelet nadir was less than 50 x 10(9)/L in 13 patients. Four patients had microscopic hematuria, two had grade 3 gastrointestinal toxicity, and one had a transient episode of delirium and blurred vision.

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.
