Patients with ARF and haematological malignancy (excluding myeloma), presenting to a single unit over 10 years were analyzed to see if patients likely to benefit from intensive renal supportive therapy could be identified. 31 episodes of ARF were identified in 29 patients (mean age 51 +/- 2.9 yr): 19 were associated with acute leukaemia (13 AML, 6 ALL); 10 with lymphoma. Acute tubular necrosis (ATN) was identified as the cause of ARF in 26 cases, with sepsis (96%) and exposure to nephrotoxic drugs (88%), especially aminoglycosides, being the commonest precipitating factors. Toxic levels of the latter were commonly documented. Patient survival was 45%. Requirement for mechanical ventilation resulted in a universally fatal outcome; age greater than 55 yr and the presence of CNS symptoms or signs were also significantly associated with a poor outcome. Non-ATN causes (urate nephropathy or obstruction) carried a better prognosis. However, only 4 patients (14%) lived for more than 6 months following ARF. Thus, although a subgroup of patients more likely to benefit from treatment can be identified, the overall prognosis is poor and limited by that of the underlying disease. The potential benefit of avoiding nephrotoxic drugs, especially aminoglycosides, in these patients is highlighted by this study.

Three cases of leukemic dermal infiltrates at permanent indwelling central venous catheter insertion sites in patients with acute myelogenous leukemia are reported. Two patients had a localized soft tissue mass at the previous permanent indwelling catheter insertion site as the sole initial manifestation of relapse after achieving complete remission and undergoing bone marrow transplantation. The third patient had catheter tunnel sepsis preceding leukemic dermal infiltration. A review of the English language literature showed that this condition is rare with no specific pathogenetic mechanisms identified. Patients with unresolved catheter tunnel infections in acute leukemia and persistent chest wall masses that appear after a previous permanent indwelling catheter should have a biopsy done and be treated promptly.

Ten patients with severe hematologic malignancies (four with acute leukemia, three with multiple myeloma, one with prolymphocytic leukemia, one with malignant lymphoma and one with blastic crisis of chronic myelogenous leukemia) developed respiratory failure during the period between April 1986 and May 1990. Clinically, the patients manifested high-fever, dyspnea refractory to oxygen therapy, diffuse pulmonary rales and severe hypoxemia without evidence of cardiogenic pulmonary edema. Chest roentgenograms displayed diffuse alveolar infiltrates. Respiratory failure occurred as early as 48 hours and as late as 66 days after the administration of intensive anti-neoplastic chemotherapy. At that time leukocyte count was between 100/microliters and 54,900/microliters. Marked leukocytosis was observed in two patients with AML and PLL. Respiratory failure was preceded by sepsis in one patient with AML and by pneumonia in nine patients. DIC was diagnosed in four patients. All patients treated with high dose methyl prednisolone (mPSL) within 12 hours after the onset of respiratory failure. Only one patient required assisted ventilation. High dose mPSL had significant effect on seven of ten patients. But three patients died from progressive respiratory failure, sepsis, pneumonia and multi-organ failure.

Bleeding and septicemia are the most common causes of death in patients with acute leukemia. Additionally to thrombopenia, which is present in most patients, in part of the patients severe coagulation abnormalities are observed. The prevalence of severe coagulation abnormalities in patients with acute myeloid leukemia including all FAB types is around 12%, in patients with promyelocytic leukemia the prevalence is more than 50%. The etiology of this coagulation abnormality remains unclear. There are 3 mechanisms currently under discussion: activation of coagulation, activation of fibrinolysis and an increased activity of specific leucocyte proteases. In particular, in promyelocytic leukemia the risk of cerebral bleeding is high (10 to 15% of early deaths). The most important therapeutic consequence is an intensified thrombocyte replacement regimen. Additional therapeutic efforts, like administration of heparin or antifibrinolytic drugs, have failed to improve the prognosis of patients with severe coagulation abnormalities.

The effectiveness of sulbactam/cefoperazone (SBT/CPZ) on severe infections associated with hematological diseases was evaluated in a nation-wide multicenter clinical study. SBT/CPZ (4-6 g/day), a 1:1 combination of SBT and CPZ, was given intravenously to 437 patients with hematological disorders. The underlying diseases included acute nonlymphocytic leukemia, acute lymphocytic leukemia, malignant lymphoma, multiple myeloma, myelodysplastic syndrome and others. Thus, 94.3% of the patients had hematological malignancies. The complicating infections included sepsis in 41 cases; sepsis suspected in 205; pneumonia in 47; urinary tract infection in 15; fever of unknown origin in 59; and others in 70. Clinical efficacies of SBT/CPZ were as follows; markedly effective, 83 cases; effective, 170; fairly effective, 59; and ineffective, 110. The efficacy rate (markedly effective plus effective) was 60.0% as a whole. The efficacy rate of SBT/CPZ in sepsis and suspected cases, which accounted for 56.3% of the infections, was 59%. Mild side effects such as skin rash were observed in 15 patients (3.1%). As for abnormal laboratory test results, transient increases in GOT, GPT, A1-P, LDH, etc. were observed in 42 patients (8.6%). Therefore, SBT/CPZ is considered to be a useful drug in empiric therapy for severe infections associated with hematological diseases.

Intensive sequential chemotherapy with mitoxantrone, 12 mg/m2/d on days 1 through 3, etoposide, 200 mg/m2/d as a continuous infusion on days 8 through 10, and cytarabine, 500 mg/m2/d as a continuous infusion on days 1 through 3 and 8 through 10 was administered to 72 patients aged less than 60 years with previously treated acute myelogenous leukemia (AML). Forty patients had refractory AML (nonresponse to prior therapy, early first relapse, or multiple relapse) and 32 had late first relapse. Sixty-one percent of patients, with a 95% confidence interval (CI) ranging from 49% to 72%, achieved complete remission (CR), including 45% (CI: 30% to 62%) of refractory patients and 81% (CI: 64% to 93%) of late first relapse patients. Twenty-nine percent of patients (CI: 19% to 41%) did not respond to therapy and 10% (CI: 4% to 19%) died from therapy-related toxicity. Median duration of aplasia was 30 days. Nonhematologic WHO grade 3 or more toxicity included sepsis (57% of patients), vomiting (10%), mucositis (35%), diarrhea (7%), skin rash (6%), and hyperbilirubinemia (11%). Postinduction therapy was attempted in 36 of 44 CR patients: 16 of them received a second course of the same regimen, 7 received maintenance chemotherapy, 4 underwent autologous bone marrow transplantation (BMT), and 9 allogeneic BMT. At a median follow-up of 20 months, 23 of the 44 complete remitters have relapsed, 1 to 14 months after achievement of CR, including 19 of 31 patients not undergoing BMT. Median survival is 7 months with 16% (CI: 4% to 28%) projected survival at 47 months. Median disease-free survival is 6 months with 21% (CI: 3% to 39%) of CR patients projected to remain disease-free at 46 months. Twenty-six percent (CI: 13% to 43%) of the evaluable patients who did not receive transplantation had inversion of CR duration. Among patients younger than 50 years, there was no significant difference in disease-free survival between patients receiving postinduction chemotherapy and those receiving BMT. We conclude that this chemotherapy regimen is highly efficient and could be used as first-line therapy in young patients with AML.

Because the use of cisplatin-based chemotherapy for ovarian carcinoma has not significantly improved 5-year survival rates compared with either whole-abdominal radiation (WAR) or single-agent chemotherapy, a pilot study was begun to assess the feasibility of concomitant radiation and chemotherapy. Eleven previously untreated patients with Stages III and IV ovarian carcinoma were treated concomitantly with 2000 cGy of WAR and intraperitoneal (IP) cisplatin followed by additional IP cisplatin after debulking surgery. Toxicity was moderate to severe. Sixty-four percent of patients had Grades 3 to 4 hematologic toxicity, and 36% required hospitalization for sepsis during WAR/IP cisplatin. Hematologic toxicity was less pronounced during IP cisplatin alone. All patients experienced moderate gastrointestinal toxicity. The average percentage of total body weight lost was 13.5%. Fifty-five percent of all patients demonstrated a complete clinical response to therapy, and patients with minimal postoperative residual disease fared better. One patient with persistent disease had acute nonlymphocytic leukemia (ANLL) 24 months after initial diagnosis. No patients with residual disease greater than 20 mm survived, while 50% of patients with less than 20 mm are clinically free of disease. Toxicity appears to be additive with the combination of WAR and IP cisplatin. Therapeutic efficacy was comparable with standard chemotherapy regimens, but no therapeutic or survival advantages were demonstrated with the use of this treatment protocol.

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.

At the Clinic for Hematology of the Military Medical Academy in Belgrade two patients had been treated from November, 1983 to July, 1986, in whom the existence of chronic myelogenous leukemia (CML) was established with negative Ph'-chromosome, as well as the existence of acquired partial erythrocyte aplasia (APEA). In the male patient of 58 years of age and the female patient of 71, APEA was established at the same time as CML. The maladies showed to be refractory to antileukemia (busulfan, hydroxyurea) and immunosuppressive (corticosteroid, androgen) therapy in both of the patients, while in the first patient splenectomy was also without effect on the course of the disease. Serumal inhibitors of erythropoiesis were not registered. After 18 months of disease duration one patient had a blastic transformation of CML into acute myeloblastic leukemia (AML) of the M1 form, and death appeared under the clinical manifestation of sepsis during iatrogenic aplasia of the bone marrow. The other patient died 32 months after start of illness because of intracranial hemorrhage, without signs of HML metamorphosis. In the discussion, previous illnesses are considered--kidney tuberculosis and polyarthralgias--as well as the applied treatment of these illnesses (antituberculotics and nonsteroid antirheumatics) as possible etiological factors in the appearance of APEA. The mutual link between APEA and CML, though exceptionally rare, is possible, and erythroblastopenia can precede or occur simultaneously with CML or during its treatment. APEA is usually the sign of CML terminal metamorphosis into acute leukemia, though it sometimes coexists with CML as an independent malady.

Mitoxantrone in combination with VP-16 proved to be effective in refractory and relapsed acute myeloid leukemia (AML), with 42% of patients achieving complete remission (CR). The aim of this study was to assess whether the addition of cytosine arabinoside increased the response rate at a tolerable toxicity. The regimen consisted of mitoxantrone (M) 10 mg/m2 i.v. days 4-8, cytosine arabinoside (A) 100 mg/m2 continuous infusion days 1-8, and etoposide (VP-16) (V) 100-120 mg/m2 i.v. days 4-8 (MAV protocol) for relapsed and refractory AML. Thirty-six patients were treated, with a median age of 51 (20-73) years. For induction therapy one to two MAV cycles and for consolidation therapy two courses were scheduled. Twenty-one (58.3%) patients attained a complete remission (CR), with a median duration of 4.5 (1-12+) months. The median survival of all patients was 5.5 (0.5-15.5+) months. Four patients died in CR from chronic infections or after consolidation therapy with MAV. In evaluable patients, times to greater than 500 granulocytes/microliters and greater than 25,000 platelets/microliters were 23 (7-46) and 23 (6-44) days, respectively. In 54 evaluable MAV courses the following toxicity was observed (WHO grades 3/4): 26%, nausea and vomiting: 9%, hemorrhage; 6%, bilirubinemia; 11%, diarrhea; 22%, mucositis; 6%, local infection; 20%, septicemia; 13%, fever of unknown origin; 2%, cardiac arrhythmia; 7%, congestive heart failure. We conclude that MAV therapy is a highly active antileukemic combination with acceptable toxicity, which is recommended for further clinical trials in untreated AML.
