We treated 13 adult patients with acute leukemia or chronic myelocytic leukemia (CML) in blast phase using succinylated Acinetobacter glutaminase-asparaginase (SAGA) administered on a daily dose schedule. SAGA reduced the peripheral blast count in two patients with acute lymphoblastic leukemia and two with blastic CML; however, no patient achieved either complete or partial remission. Marked central nervous system toxic effects (encephalopathy and coma) were observed, limiting treatment in patients whose disease appeared responsive; this effect finally prompted early discontinuance of the trial. Other toxic effects observed included nausea, hyperglycemia, and respiratory alkalosis. Hypersensitivity reactions to the enzyme were not seen. Pharmacologic analyses showed that prolonged blood glutamine depletion was achieved only by daily enzyme administration; however, we noted the importance of performing amino acid analysis on blood which was deproteinized immediately following phlebotomy. Our results demonstrate excessive central nervous system toxicity when glutaminase-asparaginase is administered on a daily schedule. Because of this effect, we propose that future trials of similar enzymes be limited to short courses of enzyme therapy, possibly with the addition of antimetabolites or amino acid analogs, which could enhance the antitumor effect without increasing toxicity.

Oral 6-thioguanine (6-TG) is an S-phase antimetabolite with significant activity against acute leukemia. Preliminary reports of activity of iv 6-TG indicated significant activity against advanced colorectal cancer. We conducted a phase II study of iv 6-TG in 29 patients with advanced measurable colorectal cancer. Only one transient partial response occurred. Toxic effects included mild myelosuppression, nausea, vomiting, and minor ECG changes. We discourage further use of iv 6-TG in the dose and schedule we used to treat advanced colorectal cancer.

53 patients with advanced and measurable cancerr were treated with vindesine in doses of 3 mg/m2 (pretreated) and 4 mg/m2 (non pretreated) i.v. once weekly. 48 patients are evaluable for response: of 14 patients with squamous cell carcinoma of the lung, 1 partial remission (PR), 1 minor response (MR) and 1 no change (NC) were observed. In 5 patients with large cell carcinoma of the lung: 1 NC. In 3 with adenocarcinoma of the lung: 1 MR. One patient with nasopharyngeal carcinoma had progressive disease. Stable disease was observed in a patient with carcinoma of the tongue and in a patient with adenocarcinoma of the esophagus. Four patients with colorectal carcinoma had progressive disease. One MR was observed in a patient with breast cancer, while all of the other 3 patients had progressive disease. One carcinoma of the penis was stable. One MR was observed in a patient with Hodgkin's disease. One PR was observed in a case with no-Hodgkin's lymphoma. A patient with acute leukemia had progressive disease. Among 9 patients with malignant melanoma, 3 had an MR and 1 patient had stable disease. A patient with fibrosarcoma had progressive disease. Observed toxicity included leukopenia, thrombocytopenia, anemia, paresthesias, constipation, jaw pain, nausea, stomatitis, alopecia, loss of taste, pruritus and skin rash, weakness and fatigue.

A phase I trial of diglycoaldehyde (Inox) in children with leukemia established that the maximum tolerated dose of a 5-day schedule was 1.5 g/m2/day. A phase II study was undertaken by the Children's Cancer Study Group to evaluate the efficacy of this dose. Forty-seven children with acute leukemia refractory to conventional forms of therapy were entered in the study: 29 patients with acute lymphocyte leukemia/acute undifferentiated leukemia and 18 with acute nonlymphocytic leukemia. Inox was administered at a dose of 1.5 g/m2 as a 4-6 hour iv infusion daily for 5 days every 14 days. Toxic effects included myelosuppression, proteinuria, nausea, vomiting, diarrhea, local tissue reactions, hypocalcemia, transitory serum amylase elevation, and transitory hypotension. There was one life-threatening episode of drug-related renal toxicity. Of the 27 patients who received a minimum of two courses, partial remissions were observed in two patients with acute nonlymphocytic leukemia. Inox was inactive against advanced acute lymphocytic leukemia.

High-dose thymidine (dThd) was given to 12 patients with advanced hematological and solid tumors. The dose schedule used was 75 g/sq m/day, given i.v. continuously for 5 days or more. Myelosuppression, especially leukopenia, was the dose-limiting toxicity. Nonhematological toxicities affected the gastrointestinal tract (nausea, vomiting, anorexia, diarrhea, and indigestion) and the central nervous system (somnolence, headache, visual illusions, and memory impairment). Patients who had received cumulative doses of dThd developed alopecia. Thymine crystals were noted in the urine after refrigeration. Tumor regression (less than partial remission) occurred in one patient with melanoma. Three of four patients with acute leukemia had a fall in peripheral white blood cell counts and blasts but no marrow improvement. Four patients with adenocarcinoma (three colon, one unknown primary) had stable disease. Pharmacokinetic studies revealed that, at a dThd dose of 75 g/sq m/day, millimolar concentrations of dThd and thymine can be achieved in the plasma. The half-life of dThd was approximately 100 min. One-third of the plasma concentrations was measurable in the cerebrospinal fluid. dThd was mainly excreted by the kidneys.

Seventy-eight transfusions of autologous platelets were given to eight alloimmunized patients receiving curative chemotherapy for acute leukemia. Platelets were collected at regeneration of hematopoiesis after a chemotherapy cycle, cryopreserved with 5% dimethylsulfoxide in liquid nitrogen, and retransfused during bone marrow aplasia following the next treatment cycle. The in vitro platelet recovery after freezing, thawing, and washing was 85 +/- 4%. The in vivo corrected count increment 1 h after autologous platelet transfusions was 11 +/- 5 x 10(9)/l. With the exception of moderate urticaria and slight nausea each after one transfusion, no immediate or chronic side effects occurred. The bleeding time was shortened and hemorrhage during bone marrow aplasia was prevented in all alloimmunized patients by autologous platelet transfusions.

Thirty adult patients with relapsing or refractory acute leukemia were treated with mitoxantrone 10 mg/m2 daily by 20-min intravenous infusion for 5 days and cytosine arabinoside (Ara-C) 200 mg/m2 daily by continuous infusion for 5 days. Complete remission was obtained in 9 of 15 patients (60%) with acute myeloblastic leukemia (AML), with a mean duration of 6 months (range 2-12 months). Among 15 patients with acute lymphoblastic leukemia (ALL), complete remission was obtained in 5 patients (33.3%), with a mean duration of 2 months. Partial remission was achieved in 2 patients with AML and 1 patient with ALL. Myelosuppression developed in all patients following chemotherapy. Nonhematologic side effects consisted of nausea, vomiting, mild alopecia, stomatitis and transient hepatic dysfunction. No cardiopulmonary toxicity or neurotoxicity was observed. Our therapeutic responses are similar to those obtained with high-dose Ara-C and mitoxantrone but with less toxicity.

A nationwide multi-center cooperative phase II clinical study of irinotecan hydrochloride (CPT-11) was conducted to evaluate its efficacy in intractable malignant lymphoma and acute leukemia. In malignant lymphoma, one course of CPT-11 consisted of intravenous drip infusion at a dose of 40 mg/m2 once daily for 3 consecutive days, performed once a week. In acute leukemia, one course of CPT-11 consisted of intravenous drip infusion at a dose of 15 to 20 mg/m2 a day twice daily for 7 consecutive days (1 cycle), performed every 2 to 4 weeks. Among the 79 patients with malignant lymphoma and 50 patients with acute leukemia enrolled in the study, 66 and 41 patients, respectively, completed treatment. These patients had all undergone chemotherapy prior to treatment. Among the malignant lymphomas, the response rate in non-Hodgkin's lymphoma (NHL), including 9 CRs, was 42% (26/62, 95% CI: 30-54%); of these there was a response rate of 39% (5/13), including 1 CR, in adult T-cell leukemia (ATL) as well. In Hodgkin's disease (HD), on the other hand, there were no cases in which efficacy was demonstrated (0/4). The overall response rate in malignant lymphoma was 39% (26/66), and the response rate even among the recurrent intransigent cases was 42% (16/38). The 50% survival time (MST) in the 74 eligible cases of malignant lymphoma was 153 days. In acute leukemia, on the other hand, partial remission was observed in 2 of 17 cases (12%) of acute lymphocytic leukemia (ALL), but no cases of remission were observed in the 24 patients with acute myelogenous leukemia (AML). The overall remission rate in acute leukemia was 5% (2/41, 95% CI: 1-14%). The principal adverse effects were myelosuppression in malignant lymphoma and gastrointestinal symptoms, including diarrhea, nausea/vomiting, anorexia and abdominal pain, in both malignant lymphoma and acute leukemia, and there was little organ damage to the heart, liver or kidney. Myelosuppression and gastrointestinal adverse effects were severe in some of the patients, so caution is required. Based on the above findings, CPT-11 appears to be efficacious in the treatment of non-Hodgkin's lymphoma.

50 cases were treated with Myelodysplastic Syndrome (MDS) by combined TCM-WM therapy. They were classified into RA 17 cases, RAS 6, RAEB 19, CMML 1 and RAEBT 7. The patients were divided into two groups, one with RA and RAS receiving treatment of hemopoietic and immune drugs plus Chinese medicinal herbs, the other with RAEB, CMML and RAEBT receiving treatment of LD Ara-c and LD Hom chemotherapy plus medicinal herbs. The effective rates were 47.83% and 62.96% respectively, the total effective rate being 56%. 6 cases (RAEB 4, RA 1, RAS 1) were treated with all-trans retinoic acid used as an inducer of differentiation, 2 of them were effective. 11 patients with MDS who had transformed into acute leukemia were treated by LD Ara-c and combined TCM-WM chemotherapy, the remission rate was 54.55% and the survival period was 9-27 months after remission. In some cases low dose chemotherapy resulted in hemocytopenia, bone marrow inhibition, infection, mild nausea and anorexia.

The purpose of this study was to define, in a phase I study in leukemia, the maximally tolerated dose (MTD), major toxicities, and possible antitumor activity of Topotecan, a new topoisomerase I (topo I) inhibitor. Topotecan was delivered by a 5-day continuous infusion every 3 to 4 weeks to patients with refractory or relapsed acute leukemia, at doses ranging from 3.5 mg/m2 to 18 mg/m2 per course. Twenty-seven patients were treated, including 17 patients with acute myelogenous or undifferentiated leukemia, 7 with acute lymphocytic leukemia, and 3 with chronic myelogenous leukemia in blastic phase. Severe mucositis was the dose-limiting toxicity occurring in two of five patients treated with Topotecan 11.8 mg/m2 per course; a third patient had prolonged myelosuppression. At the MTD of 10 mg/m2 per course, 1 of 12 patients had severe mucositis and 5 had mild-to-moderate mucositis. Nausea, vomiting, diarrhea, and prolonged myelosuppression were uncommon. Three patients (11%) achieved a complete response, two (7%) had a partial response, and one (4%) had a hematologic improvement. The overall complete plus partial response rate was 19%, and 24% in acute myelogenous or undifferentiated leukemia. A novel in vitro assay that quantifies Topotecan-stabilized topo I-DNA complexes in patient samples was used, which demonstrated heterogeneity in the ability of Topotecan to interact with topo I, the intracellular target of Topotecan. This phase I study defined the MTD of Topotecan to be 10 mg/m2 by continuous infusion over 5 days every 3 to 4 weeks in patients with refractory or relapsed acute leukemia. Severe mucositis was the dose-limiting toxicity. Future studies will define the precise activity of Topotecan in different leukemia subsets, its efficacy in combination with other antileukemic drugs, and correlations between Topotecan-induced topo I-DNA complex formation and individual patient response to Topotecan.
