Both mitoxantrone and etoposide have been shown to be active in monotherapy trials of relapsed and refractory acute myelogenous leukemia (AML). This phase II study was undertaken to assess the antitumor activity and toxicity of the combination in refractory and poor-risk AML. The regimen consisted of mitoxantrone, 10 mg/m2/d intravenously (IV), and etoposide, 100 mg/m2/d as short infusion, both on days 1 to 5. Sixty-one patients are evaluable for response and toxicity. Twenty-one were primarily refractory to conventional courses of cytarabine, daunorubicin, and thioguanine; 20 patients had poor-risk first relapse (relapse within 6 months of first complete remission [CR] or relapse under continuous maintenance therapy); 11 had second or subsequent relapses; and nine developed secondary AML after myelodysplastic phase or myelofibrosis. Twenty-six patients (42.6%) attained a CR and seven (11.5%) a partial remission (PR). The median duration of continuous CR was 4.7 months, with a range of 21 days to 14 months, excluding four patients who underwent autologous bone marrow transplantation. Severe myelosuppression was observed in all patients, with a median time to CR of 49 days. Nonhematologic toxicity included stomatitis (mainly grade 1 and 2) in 41 patients, nausea (mainly grade 1 and 2) in 44, infections (mainly grade 3) in 33, and fever of unidentified origin in 11. Other than transient, mild cardiac failure in nine patients, in some of them combined with grade 1 to 2 tachyarrhythmia, no other drug-related cardiac events were observed. Two cases of early death within the first 6 weeks of treatment were registered. Thus, the combination of mitoxantrone and etoposide is a highly active and well-tolerated regimen for refractory and poor-risk AML.

A phase II study of the oral agent methyl 6-[3-(2-chloroethyl)-3-nitrosoureido]-6-deoxy-alpha-D-glucopyranoside (MCNU tablet) for myeloproliferative disorders was performed. Fifty-two patients were treated with MCNU tablets and 43 patients were evaluated for clinical effects and 45 for adverse effects. The standard regimen was as follows; oral administration of 50mg (one tablet)/body/day every 4-6 days was considered as one course, and this was repeated at 6-8-week intervals if possible, with certain modifications according to dosage, period of administration and dose interval wherever necessary. Of 16 patients with chronic myelogenous leukemia (CML) in the chronic phase, 13 achieved complete remission (CR), and 3 achieved partial remission (PR). The overall response ratio was 100%. Rapid reduction of leucocytes was detected within two weeks. One patient with CML in blast crisis achieved PR (100%). Of 15 patients with polycythemia vera, 13 showed an excellent effect (87%), and 1 a moderate effect (6.7%), the overall response ratio being 93%. In essential thrombocythemia, an excellent effect (70%) was obtained in 7 of 10 patients. One patient with myelofibrosis showed an excellent effect (100%). Nausea & vomiting (33%) and anorexia (13%) were major adverse effects, but these symptoms were observed only transiently. Liver dysfunction was also seen in 8.9% of patients, but no patient showed severe manifestations. Our study supports the contention that MCNU tablet is a useful agent against myeloproliferative disorders.

The toxic effects of high-dose busulfan (16 mg/kg) and cyclophosphamide (200 mg/kg) with autologous or syngeneic bone marrow rescue were evaluated in 19 patients (11 with acute myelocytic leukemia, one with acute lymphocytic leukemia, one with acute myelofibrosis, two with chronic myelocytic leukemia, one with Hodgkin's disease, and three with non-Hodgkin's lymphoma). Their mean age was 26 years (range, 6-50); nine patients had syngeneic and ten had autologous bone marrow rescue (six of whom had in vitro bone marrow incubation with 4-hydroperoxycyclophosphamide). Severe myelosuppression was expected and was seen in all patients; leukocyte and platelet count recovery occurred at a median of 19 days (range, 11-59) and 30 days (range, 20-89), respectively. Nausea, vomiting, and diarrhea were frequent but readily managed with vigorous medical therapy. Stomatitis was severe in 14 patients. Skin, renal, cardiac, pulmonary, and CNS complications directly attributable to drug-related toxic effects were transient and non-life-threatening. Hepatic function abnormalities were common but tended to be transient. Most patients tolerated high-dose busulfan and cyclophosphamide with manageable side effects. Hepatic veno-occlusive disease was fatal in two patients, while diffuse interstitial pneumonitis with disseminated herpes virus infection was fatal in three patients with lymphoma. All patients treated in relapse or without previous therapy had a complete tumor response. Further studies with this regimen should be pursued.

We performed an open, nonrandomized, multicenter phase-II trial to evaluate the efficacy and toxicity of 1 year of treatment with the oral iron chelator deferiprone in 38 mainly nonthalassemic patients with transfusional iron overload. Initial serum ferritin varied between 996 and 11.644 micrograms/l. Patients were treated with 3-6 g of deferiprone daily. Mean urinary iron excretion (UIE) in 36 evaluable patients was 21.0 mg/24 h and was significantly higher in the patients with thalassemia than in those with myelodysplasia. Negative iron balance was achieved in 20 patients (56%). The median duration of treatment was 10 months; due to side effects and other causes only 20 patients completed 1 year of treatment. Mean serum ferritin levels decreased from 3563 micrograms/l at the start of the trial to 2767 micrograms/l at 6 months (26 patients, p < 0.004) and to 2186 micrograms/l at 12 months (20 patients, p < 0.005). Serum ferritin levels normalized in two patients who were no longer transfusion dependent. Deferiprone was clearly not effective in three patients (two with myelofibrosis, one with myelodysplasia). One patient with myelodysplasia developed agranulocytosis after 12 months of treatment; this was rapidly reversible after stopping deferiprone. Three patients had a mild and transient decrease in white blood cell count. Other side effects leading to withdrawal from the trial consisted mainly of nausea (3 patients), arthralgia (2), and skin rash (1). No clinical signs of zinc deficiency were seen, although zinc excretion was increased in three patients. No changes were seen in liver enzymes, creatinine, antinuclear factor, T-cell subsets, cardiac function, visual acuity, and audiogram. Although our results confirm deferiprone as an effective iron chelator in patients with thalassemia and in some patients with other forms of iron overload, there is still some concern about the safety of this drug, which therefore, at this time, should be used exclusively in well-controlled clinical trials.

Men who pursue active treatment for metastatic prostate cancer face a choice between medical or surgical castration. While both alternatives have documented side-effects (e.g. loss of libido, breast enlargement and tenderness, hot flashes, and nausea), their psychosocial impacts are not well understood. As part of a study of patients' treatment decision making, we have sought to construct a patient-based measure of the salient disease and treatment-related qualities of life experienced by these men subsequent to treatment. Focus groups (15 with patients, two with wives) were used to develop candidate Likert scale questionnaire items representing quality of life issues that patients said were important. These items were combined with assessments of symptoms, comorbidity, and generic measures of functional status and well-being in a mail survey of patients treated at the Houston VAMC and two other Houston hospitals (n = 201, response rate = 63%). Psychometric analyses (principal components and multitrait scaling) were used to identify distinct dimensions of life quality; correlations with generic measures, and symptom reports were used in validation analyses. Qualitative analyses of focus group data identified three major domains of life quality: self-perceptions, anxiety about the effects of treatment, and concern with the process of decision making and treatment. Psychometric analyses identified nine reliable and valid indicators of prostate cancer-related quality of life: body image, sexual problems, spouse affection, spouse worry, masculinity, cancer-related self-image, cancer distress, cancer acceptance, and regret of treatment decision. Internal consistency (alpha) ranged form 0.71 to 0.90. Correlations with reference scales (e.g. MOS Mental Health Index, Profile of Mood States) and symptom status supported concurrent validity. Prostate cancer patients perceive a number of important psychosocial consequences of their treatment. These consequences are represented by nine scales comprising a brief (35 items) disease and treatment sensitive health-related quality of life instrument, which we will use in monitoring the outcomes of patients' treatment choices.

Nausea and vomiting are troublesome symptoms occurring in the first trimester of pregnancy. The aim of this study was to describe the impact these symptoms have on women in early pregnancy by interviewing, using a structured questionnaire, 593 pregnant women presenting with nausea and vomiting in the first trimester of pregnancy. The women were asked to complete the Rhodes index of nausea and vomiting and the MOS 36 Short Form Health Survey (SF-36). Symptoms of nausea and vomiting started early in pregnancy. Nausea was the most troublesome symptom experienced by women, both in its duration and intensity. Low scores for the SF-36 were found for all items, particularly physical functioning, energy and social functioning. The women described substantial effects on working, household duties and parenting activities. Findings from this study suggest nausea and vomiting in early pregnancy has a profound impact on women's general sense of well-being and day to day life activities.

Essential thrombocythemia (ET) is a chronic myeloproliferative syndrome characterized by thrombocythemia and increased megakaryocytes in bone marrow, thrombosis and/or hemorrhagic manifestations. We report here a ten-year experience in the treatment of ET with anagrelide (A), a non mutagenic drug that inhibits megakaryocyte maturation. Between April 1991 and June 2001, 54 ET patients were included with platelet counts > 900 x 10(9)/l in asymptomatic cases and > 600 x 10(9)/l in symptomatic ones. Age at diagnosis was 39 years (11-83). Previously 30 patients had received treatment with hydroxyurea, alpha INF, busulfan and/or 32P. At diagnosis 18 patients had microvascular obstruction, 7 thrombosis, 8 hemorrhagic manifestations and 3 both hemorrhage and thrombosis. Platelet counts at diagnosis were 1200 x 10(9)/l (600-3472) and before A 995 x 10(9)/l (520-2206). The follow-up from diagnosis was 68 months (9-172) and with A treatment 34 months (2-100). The A dose during the first week of treatment was 2.5 mg/d (1-3) and at maintenance 1.5 mg/d (1-3). Complete response was obtained in 96.3% cases, 77% with platelet counts < 400 x 10(9)/l, and 18.5% < 600 x 10(9)/l. The median time to obtain a complete response was 14 days. Transient adverse effects were present in 66% of patients (headache, nausea, abdominal distention, palpitation and edema). Mild to moderate anemia developed within 2-8 months in 40% of patients. During treatment 8 patients had microvascular obstruction with platelet counts over 400 x 10(9)/l and 7 with normal values. One patient developed myelofibrosis. Five patients died for reasons unrelated to ET. In conclusion, anagrelide was effective in reducing platelet counts and preventing mayor thrombotic events.

We investigated the clinical activity of the farnesyl transferase inhibitor R115777 in 22 patients with chronic myelogenous leukemia (CML) in chronic, accelerated, or blastic phase and in 8 patients with myelofibrosis (MF) and 10 patients with multiple myeloma (MM). R115777 was administered at 600 mg orally twice daily for 4 weeks every 6 weeks. Seven patients with CML (6 in chronic phase, 1 in advanced phase) achieved complete or partial hematologic response. Four of them had a minor cytogenetic response. Responses were transient, with a median duration of 9 weeks (range, 3-23 weeks). Two patients discontinued therapy because of toxicity while in complete hematologic response. Two MF patients had a significant decrease in splenomegaly, one had normalization of white blood cell count and differential, and one became transfusion independent. One patient with MM had a reduction in monoclonal protein of 34%. Adverse events included nausea in 22 patients (55%; all grade 2 or lower) and fatigue in 19 (48%; grade 3 or higher in 1). Other grade 3 or 4 toxicities included skin rash (4 patients, 10%), peripheral neuropathy (2 patients, 5%), and liver toxicity (2 patients, 5%). Patients who responded to therapy had significantly higher plasma vascular endothelial growth factor (VEGF) concentrations prior to treatment than nonresponders. Plasma concentrations decreased significantly during therapy among responders. R115777 showed clinical activity in patients with CML and MF. The effect on VEGF needs to be further investigated to determine whether this might be a possible mechanism of action of R115777.

Few treatment options exist for patients with myelofibrosis (MF), and their survival is significantly shortened. Activating mutation of the JAK2 tyrosine kinase (JAK2(V617F)) is found in approximately 50% of MF patients. CEP-701 is a tyrosine kinase inhibitor that inhibits JAK2 in in vitro and in vivo experiments. We conducted a phase 2 clinical study of CEP-701 in 22 JAK2(V617F)-positive MF patients (80 mg orally twice daily), and 6 (27%) responded by International Working Group criteria (clinical improvement in all cases): reduction in spleen size only (n = 3), transfusion independency (n = 2), and reduction in spleen size with improvement in cytopenias (n = 1). Median time to response was 3 months, and duration of response was more than or equal to 14 months. No improvement was seen in bone marrow fibrosis or JAK2(V617F) allele burden. Phosphorylated STAT3 levels decreased from baseline in responders while on therapy. Eight patients (36%) experienced grade 3 or 4 toxicity, and 6 (27%) required dose reduction. Main side effects were myelosuppression (grade 3 or 4 anemia, 14%; and thrombocytopenia, 23%) and gastrointestinal disturbances (diarrhea, any grade, 72%; grade 3 or 4, 9%; nausea, grade 1 or 2 only, 50%; vomiting, grade 1 or 2 only, 27%). In conclusion, CEP-701 resulted in modest efficacy and mild but frequent gastrointestinal toxicity in MF patients. The study was registered at http://clinicaltrials.gov as NCT00494585.

We treated 37 patients with polycythemia vera with imatinib mesylate (IM). The overall response rate was 49%. Thirty percent had a complete response, and 19%, a partial response. Thirty-one patients were treated for >120 days. Frequent side effects included nausea, diarrhea, edema, and skin rash. Whereas IM was effective in controlling erythropoiesis and reducing spleen size it was ineffective in controlling thrombocytosis. Normocellular marrow developed in 4 patients who had a complete response. Progression to overt myelofibrosis occurred in 3. Nevertheless, 6 patients have had a sustained complete response while on IM for >6 years. These patients were young, had high phlebotomy requirements, and only slightly elevated platelet counts. Therefore, we believe there may be a role for IM in patients with these characteristics whose disease cannot be controlled by, or as an alternative to, other myelosuppressive treatments.
