3-Deazauridine, a uridine analog, was administered to 36 patients with acute leukemia by both intermittent and continuous iv infusion at doses ranging from 400 to 6000 mg/m2/day x 5, repeated at 1--3-week intervals. There were no complete or partial responses but three patients showed hematologic improvement. Major toxic effects were myelosuppression, stomatitis, vomiting, diarrhea, and skin erythema. Daily doses greater than 3000 mg/m2 were associated with significantly increased toxicity, including three drug-related deaths. The recommended dose for future studies is 2500 mg/m2/day as a continuous 5-day infusion.

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.

6-Thioguanine (6-TG) was administered as a continuous i.v. infusion for 7 days to 24 patients with relapsed or refractory acute leukemia or in the blast phase of chronic granulocytic leukemia. The daily dose of 6-TG was escalated from 37.5 mg/m2 to 160 mg/m2. Stomatitis was dose-related and dose-limiting with a maximum tolerated dose of 120 mg/m2 daily. Cutaneous reactions were dose-related but not dose-limiting. The recommended dose for phase II trials in acute leukemia is 120 mg/m2 per day as a continuous infusion for 7 days. There were two complete and four partial remissions among all patients. At the suggested phase II dose of 120 mg/m2 there were two complete remissions and one partial remission in five evaluable patients.

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.

Sixteen adult patients with relapsed (7 patients) or refractory (9 patients) acute leukemia received mitoxantrone (10 mg/m2 per day for 3 days) and etoposide (200 mg/m2 per day for 3 days) with escalating dose of cyclosporin A (CsA) from a loading dose of 2 mg to 6.5 mg/kg per 2 h followed by 3 days continuous infusion of 5-15 mg/kg per day. The major toxicities were stomatitis and prolonged aplasia, occurring for 15 mg/kg per day of CsA. Transient conjugated hyperbilirubinemia occurred in all patients, and was CsA dose-dependent (r = 0.7). Adequate serum levels of CsA (> 1 microgram/ml) were obtained in 3/6 patients treated with 10 mg/kg per day and 4/4 patients with 15 mg/kg per day. The pharmacokinetic of mitoxantrone showed an unusual increase of carboxylic metabolites, parallel to CsA levels. We observed six responses (two complete and four partial remissions), and eight resistances. Two patients died at days 3 and 8 from sepsis. Before treatment, 7/16 patients tested for P-gp with C219 were positive (> 10% positive cells). 3/6 responders were P-gp-positive. At time of leukemic regrowth, cells expressing P-gp before therapy reverted to P-gp-negative cells.

The authors report a clinical investigation on 49 patients: 9 with acute leukemia and 40 with chronic leukemia. A file suggested by OMS was used to collect all data about patients and case histories. Patients suffering from acute leukemia, admitted to sterile rooms, were submitted to a simple clinical investigation because of their severe general conditions and to avoid any contamination. Except for a case of stomatitis caused by methotrexate, no oral disease was observed. Patients with LMC, examined with CPITN index, revealed a high presence of tartar (44.87%) and periodontal pockets, 4-5 mm deep, (23.72%). DMFT was 22.60, a rather high value caused by the large number of missing teeth. The data analysis evidences the severe clinical conditions of the patients and the urgent necessity for proper prophylactic and therapeutic treatment.

This phase I trial of idarubicin (IDA) was conducted in 32 patients with acute leukemia and chronic myelogenous leukemia (CML) in blastic crisis (CML/BC) who either had failed to achieve a complete remission (CR) after initial induction therapy or had relapsed after CR. IDA was administered at dosages ranging from an initial dose of 5 mg/m2/d for 3 days with an increment of 2.5 mg/m2/d to 15 mg/m2/d for 3 days. The dose-limiting toxicities (DLTs) were thought to be stomatitis and anorexia. The maximum tolerated dose (MTD) was determined to be 15 mg/m2/d for 3 days (45 mg/m2 per course). Bone marrow toxicity was significant when greater than 10 mg/m2/d of IDA was given. When IDA was administered at this dosage or higher, there were three CRs and four partial responses, with an overall response rate of 26.9% in 26 assessable patients. It is recommended that a phase II study be undertaken at an IDA dosage of 10 to 15 mg/m2/d for 3 consecutive days in the treatment of acute leukemia. Twenty-one of 32 patients were also studied for the pharmacokinetics of IDA. The terminal half-life (t1/2) values for IDA were 6.4 to 15.1 hours in plasma and 8.09 to 16.34 hours in blood cells. The t1/2 values for idarubicinol were much longer: 43.46 to 51.01 hours in plasma and 36.61 to 54.70 hours in blood cells. Concentrations of idarubicinol in plasma and blood cells exceeded those of IDA 2 to 4 hours after the start of treatment and remained elevated for a long time. The area under the curve (AUC) of idarubicinol in plasma was 5.16 to 8.36 times higher than that of IDA, and the AUC of idarubicinol in blood cells was 2.05 to 4.57 times higher than that of IDA. The AUCs of both IDA and idarubicinol increased dose-dependently over the dosage range of 5 to 15 mg/m2/d. When two-compartment multiple-dose models were used, plasma t1/2 alpha and t1/2 beta values of IDA were 0.25 +/- 0.13 and 9.4 +/- 3.4 hours, respectively. The steady-state volume of distribution (Vdss) was 934.9 +/- 370.7 L/m2, and the plasma clearance was 82.3 +/- 29.7 L/h/m2. The urinary excretion of IDA and its metabolite was low. The mean cumulative urinary recovery rates were 2.04% for IDA and 11.53% for idarubicinol up to 7 days.

We estimated the utility of daily oral administration of etoposide (ETOP) in 25 cases of refractory hematological malignancies who had been admitted to our hospital between February, 1988 and October, 1995. Patients were 9 cases of malignant lymphoma, 7 cases of adult T cell leukemia (ATL), 7 cases of acute leukemia, 1 case of primary macroglobulinemia, and 1 case of chronic lymphocytic leukemia (CLL). Eight cases were elderly patients over 65 years old, 7 cases were refractory to previous chemotherapies, and 13 cases were relapsed cases. ETOP was administered at 25 or 50 mg per day for at least more than 3 consecutive weeks, if the peripheral white blood cell count exceeded 1,000/microliter. Complete and partial responses were obtained in 64% of all cases, especially in 81% of malignant lymphoma and ATL. Probability of survival for 3 years of malignant lymphoma and ATL was 36.7%. As mild toxicities, 2 cases (8%) had nausea and vomiting, 2 cases (8%) had diarrhea, and 3 cases (12%) had stomatitis. Grade 3 leukocytopenia was observed in 16% of cases. Twelve out of 16 evaluable patients recovered in performance status (PS) after this therapy. Daily oral administration of ETOP might be an effective therapy for refractory hematological malignancies, especially for malignant lymphoma.

Vinorelbine (Navelbine) is a unique semi-synthetic vinca-alkaloid with a favorable safety profile that has demonstrated significant antitumor activity in patients with non-small cell lung cancer, advanced breast cancer, advanced ovarian cancer and Hodgkin's disease. The most common dose-limiting toxicity is neutropenia, while other reported toxicities are minimal. Mitoxantrone (Novantrone) is an anthracene derivative that has demonstrated antitumor activity in patients with breast cancer, ovarian cancer, acute leukemia, and lymphoma. Mitoxantrone also has a very favorable toxicity profile with significantly less nausea and vomiting, alopecia, and stomatitis as compared with anthracyclines. The dose-limiting toxicity for mitoxantrone is leukopenia. The study was designed to determine the safety and maximally tolerated dose of IV vinorelbine used in combination with a fixed dose of mitoxantrone for the treatment of patients with refractory solid tumors. Vinorelbine was administered on days 1 and 8 of the treatment regimen as a short IV infusion. The starting dose was 15 mg/m2. Mitoxantrone was administered as a 20-min infusion on day 1 only at a fixed dose of 10 mg/m2. Seventeen patients with solid malignancies were entered in the study. For personal reasons, one patient decided to discontinue the treatment after day 1 of cycle 1. Therefore, 16 patients were evaluable for toxicity. The main toxicity was myelosuppression which was dose-limiting and resulted in dose reductions and delays. The use of G-CSF had a minimal overall impact on this regimen. Stable disease was observed in three cases. In patients previously treated with chemotherapy, the maximally tolerated dose was defined as vinorelbine 20 mg/m2 on days 1 and 8 and mitoxantrone 10 mg/m2 on day 1 without growth factor support. These doses can be recommended for phase II study of the regimen as salvage treatment.

The purpose of this study was to determine the maximally tolerated dose of doxorubicin administered during two cycles of intensive chemotherapy with cyclophosphamide and doxorubicin without stem cell support in patients with advanced cancer and to assess the cumulative cardiac toxicity of the regimen by noninvasive radionuclide imaging and by pre-and postchemotherapy endomyocardial biopsies. Thirty-eight patients (thirty-six with high risk or metastatic breast cancer) were treated in a dose-escalation trial using a fixed dose of i.v. cyclophosphamide (4.2 g/m2) administered over 2 h on day 5 and escalating doses of doxorubicin (50-175 mg/m2) given as a 96-h continuous i.v. infusion on days 1-4, using Filgrastim (granulocyte colony-stimulating factor) for hematological support beginning on day 6. All patients underwent pretreatment, and 28 patients underwent postchemotherapy endomyocardial biopsies. Twenty-nine of 38 patients received two cycles of treatment (median number of days between cycles, 44; range, 34-62). Twenty-one patients had received doxorubicin previously at cumulative dose levels </=150 mg/m2; all patients had pretreatment endomyocardial biopsy scores less than 1. One patient treated at the highest dose level of doxorubicin (175 mg/m2) developed symptoms of mild congestive heart failure following two cycles of chemotherapy. Pre- and posttreatment radionuclide ejection fractions were 65 and 45%, respectively; this patient had a posttreatment endomyocardial biopsy score of 1 (damage to <5% of myocytes). One additional patient at this dose level had an asymptomatic biopsy score of 1, with a decrease in ejection fraction from 62 to 43%; this recovered to 58% 5 months after completion of chemotherapy. Six additional patients treated at lower dose levels had abnormal posttreatment endomyocardial biopsies without abnormal posttreatment ejection fractions. Nine patients received only one cycle of chemotherapy: five patients due to decreased cardiac ejection fraction following cycle 1 (two of these patients had normal endomyocardial biopsies, and two patients had biopsy scores of 1); one patient secondary to tumor progression following cycle one; one patient due to persistently detectable Clostridium difficile toxin in the stool; one patient refused cycle two; and one patient died following cycle one of complications related to sepsis. A single patient experienced a grand mal seizure associated with orthostatic hypotension, which was considered the dose-limiting toxicity. The median duration (over two cycles) of granulocytopenia (absolute granulocyte count <500/microliter) at the maximally tolerated dose level of 150 mg/m2 was 8.5 days (range, 5-13 days), and the median duration of thrombocytopenia (platelets <20,000/microliter) was 2.5 days (range, 0-9 days). The median duration of hospitalization including chemotherapy administration was 23 days (range, 19-36 days). Other toxicities included stomatitis, fever, diarrhea, and emesis. One patient developed acute leukemia 54 months posttreatment. We conclude that two courses of high-dose cyclophosphamide and doxorubicin using granulocyte colony-stimulating factor are feasible and safe with tolerable myocardial toxicity as evidenced by serial endomyocardial biopsies. The dose-limiting toxicity encountered was a grand mal seizure. The recommended Phase II dose is doxorubicin 150 mg/m2 administered as a 96-h infusion on days 1-4, with cyclophosphamide 4. 2 g/m2 on day 5 and G-CSF 5 microgram/kg/day started on day 6 and administered until the total WBC is above 10,000/microliter for three consecutive days.
