The purpose of this study was to determine symptom prevalence, characteristics, and distress in children with cancer. The Memorial Symptom Assessment Scale (MSAS) 10-18, a 30-item patient-rated instrument adapted from a previously validated adult version, provided multidimensional information about the symptoms experienced by children with cancer. This instrument was administered to 160 children with cancer aged 10-18 (45 inpatients, 115 outpatients). To confirm the instrument's reliability and validity, additional data about symptoms were collected from both the parents and the medical charts, and retesting was performed on a subgroup of inpatients. Patients could easily complete the scale in a mean of 11 minutes. The analyses supported the reliability and validity of the MSAS 10-18 subscale scores as measures of physical, psychological, and global symptom distress, respectively. Symptom prevalence ranged from 49.7% for lack of energy to 6.3% for problems with urination. The mean (+/- SD) number of symptoms per inpatient was 12.7 +/- 4.9 (range, 4-26), significantly more than the mean 6.5 +/- 5.7 (range, 0-28) symptoms per outpatient. Patients who had recently received chemotherapy had significantly more symptoms than patients who had not received chemotherapy for more than 4 months (11.6 +/- 6.0 vs. 5. 2 +/- 5.1), and those patients with solid tumors had significantly more symptoms than patients with either leukemia, lymphoma, or central nervous system malignancies (9.9 +/- 7.0 vs. 6.8 +/- 5.5 vs. 6.8 +/- 5.0 vs. 8.0 +/- 6.1). The most common symptoms (prevalence > 35%) were lack of energy, pain, drowsiness, nausea, cough, lack of appetite, and psychological symptoms (feeling sad, feeling nervous, worrying, feeling irritable). Of the symptoms with prevalence rates > 35%, those that caused high distress in more than one-third of patients were feeling sad, pain, nausea, lack of appetite, and feeling irritable. Subscale scores demonstrated large variability in symptom distress and could identify subgroups with high distress. The prevalence, characteristics, and distress associated with physical and psychological symptoms could be quantified in older children with cancer. The data confirm a high prevalence of symptoms overall and the existence of subgroups with high distress associated with one or multiple symptoms. Symptom distress is relatively higher among inpatients, children with solid tumors, and children who are undergoing antineoplastic treatment. Systematic symptom assessment may be useful in future epidemiological studies of symptoms and in clinical chemotherapeutic trials. Symptom epidemiology may also provide a focus for future clinical trials related to symptom management in children with cancer.

Anaemia is a common disorder in patients with cancer, occurring in 10-40% of cases, depending upon the tumour type and chemotherapy used. It is present in nearly all patients with leukaemia at some time in the disease and in 50% of patients with lymphoma after chemotherapy. Cancer-related anaemia appears to result from a range of factors including chronic inflammation, blood loss, nutritional deficiencies, haemolysis, bone marrow infiltration by malignant cells, low serum erythropoietin (EPO) levels, and a decrease of bone marrow responsiveness to EPO. The consequences of anaemia, namely fatigue and cardiovascular symptoms, can adversely affect patients' quality of life and may even alter their response to cancer treatment. Moreover, anaemia is often associated with the presence of several adverse prognostic parameters and is also itself a predictor of poor prognosis. Furthermore, anaemia and its symptoms can be exacerbated by cancer treatment. Until recently, blood transfusions have been the mainstay of treatment for cancer-related anaemia, despite the associated risks of transfusion-related reactions and transmission of infection. By increasing haemoglobin levels and haematocrit, treatment with recombinant human erythropoietin (rHuEPO) has been shown to reduce the need for blood transfusion in patients with haematological malignancies. It is recommended that rHuEPO be administered when a patient's haemoglobin level is at risk of falling below 8g/dL, and that treatment is maintained until levels rise above 13g/dL. Consideration of the detrimental effects of anaemia on cancer patients' physical and emotional well-being and therapeutic outcome suggests that rHuEPO therapy has the potential to provide substantial clinical benefits.

Hydroxyurea, which has already been approved as a treatment for leukemia and advanced ovarian cancer, now appears to be effective in slowing HIV viral replication in virtually all immune system cells and tissues. It does not appear to cause resistance, and it also increases the activity of some antiviral drugs against drug-resistant strains of HIV. Bristol Myers Squibb, the manufacturer, no longer holds the patent on Hydroxyurea, so other companies may produce generic, low-cost variations of the drug. Hydroxyurea interferes with the functioning of targeted cells, and its ability to penetrate the brain means that it has the potential to treat neurological diseases directly caused by HIV. Hydroxyurea does not appear to increase T-cell counts, and may even lower T-cell counts. This should be a consideration for patients who already have low T-cell counts. Hydroxyurea is taken orally twice a day and is generally available at most pharmacies. However, Hydroxyurea is not likely to be available through ADAPs since it has not been approved by the FDA for use with HIV. Side effects are generally mild and include fatigue, anemia, bruising, and reduced lymphocyte production.

Common presenting symptoms of acute lymphoblastic leukemia in children are well known and include pallor, fatigue, and loss of appetite. Limb pain is sometimes described and can be misleading. We describe two recent cases seen in our emergency department, where vertebral fractures, a much rarer finding, were the only presenting symptoms that led to the diagnosis. One case had been thoroughly evaluated only 5 weeks prior to the diagnosis and included magnetic resonance imaging. The second patient was rapidly referred to our center with a history of acute lumbar pain. Emergency physicians caring for children must be aware of this rare type of presentation of leukemia.

We examined the efficacy of thalidomide in 34 patients with myelodysplastic syndromes (MDS): five RAEB-T, four RAEB, three CMML, six RARS, and 16 RA. Patients belonged to the following cytogenetic groups: 15 complex abnormal karyotypes, 12 normal karyotypes, four cases with 5q- as sole anomaly and three single aberrations. The median thalidomide dose was 400 mg/day (25/34 patients). Four patients discontinued the study after less than 5 weeks, because of fatigue (three) or skin rash (one). One patient died of heart failure after 4 weeks. In the remaining 29 patients (median follow-up: 13 months), treatment responses were classified according to the IWG criteria. Six patients (four RA, two CMML) showed progressive disease (five with transformation into AML) and four patients showed stable disease. Hematological improvement (HI) was observed in 19 patients. Nine of the responders (three RA, one RARS, two RAEB, three RAEB-T) achieved partial remission with granulocytes > or = 1500/microl, Hb > 11 g/dl and platelets > or =100,000/microl. Four patients (one RARS, one CMML, one RAEB, one RAEB-T) had a major response, with platelet and RBC transfusion independence. Six patients (five RA, one RARS) showed minor responses (three HI-E, two HI-E+HI-P, one HI-E+HI-N). Hematological improvement occurred after a median of 2 months of thalidomide treatment. Two patients (RAEB-T) relapsed after a partial remission lasting 8 and 16 months, respectively. In summary, a therapeutic benefit was achieved in 19 of 34 study patients (56%).

Treatment of healthy donors with recombinant human granulocyte colony-stimulating factor (rhG-CSF) allows the mobilization and peripheralization into circulating blood of an adequate number of CD34+ cells that can then be collected by leukapheresis (PBSC). This procedure avoids the invasiveness of bone marrow harvest and the risks related to general anesthesia. The main adverse effects of rhG-CSF are: bone pain, 84%, headache, 54%, fatigue, 31%, and nausea, 13%, which are usually scored by the donors as moderate to severe, resolving within 2-3 days after discontinuation of the cytokine. Analgesics, mainly acetaminophen, are sufficient to control the pain. Less than 5% of the donors experience non-cardiac chest pain, a local reaction at the injection site, insomnia, dizziness or a low-grade fever. Discontinuation of the PBSC procedure because of adverse effects of rhG-CSF or leukapheresis is rarely necessary (0.5%) but this good tolerability can be hampered by the need, in 5-20% of cases, for an adequate venous access that requires insertion of a central or venous catheter. There are no absolute contraindications to the stimulation of healthy donors with rhG-CSF but the description of cases of non-traumatic splenic rupture, iritis, cardiac ischemia, and gouty arthritis suggests that further precautionary restrictions are advisable when deciding eligibility for PBSC collection. The main advantages for patients receiving an allogeneic PBSC transplant are the faster hematologic and immunologic recovery and the potential for a greater efficacy in advanced disease by lowering the transplant-related mortality. One of the major concerns regarding the use of rhG-CSF in unrelated healthy donors is the uncertainty about its possible role in triggering malignancy, in particular myelodysplastic syndrome and acute myeloid leukemia. There are no studies with an adequate sample size and follow-up that can answer this question but two recent retrospective studies reported that in the medium term rhG-CSF is not associated with an excess of lymphoproliferative disorders. Currently, caution on the long-term safety of the use of rhG-CSF in healthy donor is still warranted but the data so far accumulated on allogeneic PBSC transplants are encouraging both as far as concerns the good short-medium tolerability profile of G-CSF-stimulation of the donor and the potential major efficacy in leukemia patients.

Thalidomide is being increasingly used after stem cell transplantation as immunosuppression for patients with chronic graft-versus-host disease, as well as for antiangiogenesis effects in patients with multiple myeloma, brain tumors, leukemia, or other malignancies. The goal of this study was to determine if thalidomide improved the quality of life by virtue of its associated sleep-promoting, anxiety-reducing, antiwasting, and antidiarrheal effects. We therefore studied 28 patients with resistant chronic graft-versus-host disease who were treated with thalidomide (13 patients) or other immunosuppressive drugs (15) and compared them with healthy control subjects (16). All patients completed quality-of-life questionnaires prospectively before beginning regimens of thalidomide or other immunosuppressive drugs and completed similar questionnaires at 3- and 6-month intervals thereafter. The Transplant Symptom Frequency score was similar for healthy control subjects and both groups of patients with chronic graft-versus-host disease, regardless of whether they had received thalidomide or not. Quality of sleep was equally poor in patients who received or did not receive thalidomide. The most common complaint of patients with chronic graft-versus-host disease was fatigue, followed in frequency by overeating. The control group had similar concerns. This pilot study suggests that patients with chronic graft-versus-host disease have a quality of life similar to that of their health care workers, regardless of whether they are treated with thalidomide or other immunosuppressive drug, and that fatigue and overeating are the most common complaints.

Psychological factors may be associated with the outcome of cancer treatment, including bone marrow transplantation (BMT). However, studies on the issue have provided controversial results. In the present study, effects of mood status on the outcome was studied through a follow-up period of 1-3 years as well as in shorter periods (3 and 8 months) post-BMT in 72 Japanese patients with leukemia. Psychological status was evaluated 2 weeks before BMT using Profile of Mood States (POMS). The most major factor abstracted from the POMS subscales (Factor 1, mainly comprising anxiety, depression, anger, fatigue and confusion) was associated with disease-free survival rate at 3 months post-BMT. However, the factor most significantly associated with the outcome was gender. Females had better outcome than males through the period of 1-3 years as well as at 8 months post-BMT. When analyzed by gender, Factor 1 was associated with poor prognosis at 3 and 8 months in males. In females, however, Factor 1 was not significantly associated with the prognosis. The present results suggest an association between mood status pre-BMT and prognosis post-BMT in a gender-specific manner.

After alarming reports in the international press in January 2001, about leukemia in war veterans returning from the Balkans after possible exposure to depleted uranium, a follow-up was conducted of the Swedish personnel that had served in the Balkans. Questionnaires, analysis of uranium in urine, and coordination with The National Board of Health and Welfare's cancer register showed no correlation between service in the Balkans and cancer or other illnesses. Several did however experience anxiety, insomnia and fatigue that may have been caused by the stressful environment and/or the anxiety arising from the depleted uranium-debate. To lower the risk for unjustified anxiety and to be better prepared for the physical environment, the Swedish Armed Forces are working on better risk analysis before mission as well as increased health examinations both before and after mission.

We describe a 48-year-old male who developed acute myelogenous leukaemia (AML) associated with a right atrial mass. The patient was admitted with fatigue, positional dyspnoea and headache. Transthoracic echocardiography (TTE) and transoesophageal echocardiography (TEE) revealed that the right atrium was filled with a mass. Peripheral blood smear revealed 85% blasts, and bone marrow examination showed 74% myeloid blasts and 27% monocytoid cells (monoblast and promonocytes). Immunophenotypic analysis of the bone marrow aspirates showed CD13, CD14 and CD33 positivity, consistent with acute myeloid leukaemia of M4 Fab subtype. The patient achieved remission (but not cure) accompanied by near resolution of the right atrial mass following intensive chemotherapy.
