Five acute leukaemia or highly malignant lymphoma patients at a hospital in southern Sweden were interviewed about their daily living problems, their coping strategies and their opinions about the nursing care they received during the active phase of their treatment. In addition the EORTC QLQ-C30, the Global Life Quality and the Sense of Coherence scales were administered. The data were analysed from a hermeneutic phenomenological perspective and interpreted to indicate that the patients sensed a threat to their lives, loss of control, and having to live with uncertainty stemming from the disease and the treatment. They had problems with fatigue, diarrhoea, nausea and vomiting, loss of appetite, sore mouth and high temperature. However, they seemed to minimize the importance of these problems and instead focused on gaining control of the situation, developing their knowledge of the disease and relying on the support of their family. Contradictions appeared in their statements about the quality of care, the information given was said to be good but difficult to understand; although the quality of the nursing care was judged to be high it had to be asked for. That is, help was received on request. The patients' perspective of the family and the nurses should be studied in further research in order to fully understand the patients' coping strategies and how nursing care can support them.

We report our experience with 67 patients with myeloid malignancies (acute myeloid leukaemia (AML) or chronic myelogenous leukaemia (CML) conditioned with busulphan and melphalan as preparation for autologous haemopoietic cell transplantation. The major non-haematological toxicities were severe mucositis, nausea and vomiting, but the marrow aplasia was delayed and of short duration. The anti-tumor effect was appreciable with subsequent chronic phase (CP) obtained in 30/31 CML in transformation and complete remission (CR) obtained in 2/3 refractory AML. Among 32 patients treated while they had no evidence of active disease, 12 remained in CR or CP with a median follow-up of 54.7 months.

One hundred sixteen cases of leukemia patients received supra-high single dose TBI for bone marrow transplantation (BMT) with total a radiation dosage of 700-770 Gy at about 5cGy/min. Seventy patients were given ondanstron (8mg) plus dexamethasone (DXM, 10mg) for prophylaxis of TBI-induced acute nausea and vomiting, 46 patients were given paspertin (10mg) plus dexamethasone (10mg) as controls. The clinical results showed that ondansetron plus DXM achieved complete or major control of vomiting in 59/70 (84%) of cases and there was little or no nausea in 61/70 (87%), while paspertin plus DXM achieved complete or major control of vomiting only in 9/46 (20%) of cases and little or no nausea in 5/46 (11%). It is concluded that ondansetron has significantly greater advantage over paspertin in the control of acute emesis induced by TBI.

The myelodysplastic syndrome (MDS) comprises a group of clonal hematopoietic disorders derived from an abnormality affecting a multipotent hematopoietic stem cell. Despite trials testing numerous agents in patients with MDS, no single drug has yet emerged as the accepted standard of treatment. Observation and supportive care with blood products and antibiotics, when necessary, continue to be the mainstays of therapy. We administered 5-azacytidine, a cell-cycle specific ring analog of the pyrimidine nucleoside cytosine, as a continuous intravenous infusion, 75 mg/m2 per day for 7 days every 4 weeks. Patients had refractory anemia with excess blasts (RAEB) or refractory anemia with excess blasts in transformation (RAEB-T). Responses were seen in 21 (49%) of 43 evaluable patients: five (12%) in complete remission (CR, complete normalization of bone marrow and peripheral blood counts); 11 (25%) in partial remission (PR, > or = 50% restoration of the deficit from normal of all three peripheral blood cell lines, elimination of transfusion requirements, and a decrease in percentage bone marrow blasts by > or = 50% from prestudy values); five (12%) improved (> or = 50% restoration in the deficit from normal of one or more peripheral blood cell lines and/or a > or = 50% decrease in transfusion requirements). A trilineage improvement (CR and PR) occurred in 37% of the patients. The median survival for all patients was 13.3 months and the median duration of remission for those with CR and PR was 14.7 months. Mild to moderate nausea and/or vomiting was the most common side effect (63%). Myelosuppression, either bone marrow hypoplasia or drug related cytopenias requiring a reduction in the dose of azacitidine, occurred in only 33% of the patients. Prior to treatment, bone marrow erythroid progenitor cells were assayed in vitro. Colonies derived from erythroid burst-forming units (BFU-e) were undetectable in one patient and reduced in two. The number of colonies derived from erythroid colony-forming units (CFU-e)) were also reduced in two of the three patients. In the two patients with detectable colony growth prior to treatment, colony number decreased by day 8 of the first cycle, followed by a subsequent increase. Continued treatment with azacitidine led to normalization of the number of CFU-e derived colonies as well as an increase in the number of BFU-e derived colonies. This improvement in erythroid colony number correlated with the spontaneous rise in hemoglobin levels and red cell transfusion independence.(ABSTRACT TRUNCATED AT 400 WORDS)

Fludarabine is a fluorinated purine analogue with antineoplastic activity in lymphoproliferative malignancies. Noncomparative studies have shown response rates in patients with chronic lymphocytic leukaemia (CLL) that appear to be at least equivalent to those achieved with conventional therapy. Prolymphocytic leukaemia, a form of CLL which is often resistant to conventional chemotherapy, has also responded to treatment with fludarabine. Fludarabine combined with prednisone has also induced good response rates in patients with CLL but the limited data suggest that this does not offer an advantage over fludarabine alone. Several clinical trials have demonstrated a good cytoreductive response in patients with advanced, low grade non-Hodgkin's lymphoma, particularly that of follicular histology. Preliminary evidence indicates fludarabine in combination with cytarabine has therapeutic activity as salvage therapy in patients with acute leukaemia. Myelosuppression has been the major dose-limiting adverse effect reported in clinical trials of fludarabine. A reduction in CD4+ cell count may be associated with the increased incidence of fever and opportunistic infections in fludarabine recipients. Nausea and vomiting have also been commonly reported, but these are generally mild to moderate in severity. Reversible neurotoxicity has also been occasionally reported. Thus, fludarabine appears to offer a viable alternative to currently used treatments in CLL and low grade non-Hodgkin's lymphoma. Other potential areas of use for fludarabine include acute leukaemias. Waldenstrom's macroglobulinaemia and mycosis fungoides. However, trials of fludarabine in comparison with currently used therapies and also in combination with other antineoplastic agents are required to fully define its role in the treatment of lymphoid malignancies. In addition, because relapse in these diseases is common, long term trials assessing improvement in survival duration and quality of life would be of value.

A 41-year-old woman with chronic myelogenic leukemia was scheduled to undergo transplantation of bone marrow. The patient complained of nausea and vomiting following the initiation of chemotherapy. One day prior to the planned termination of chemotherapy, the patient developed left-sided abdominal pain. Physical examination and imaging examination indicated the possibility of acute abdomen associated with bleeding or herniation. For therapeutic and diagnostic purposes, an emergency operation was performed. A 6 x 5 cm hematoma was detected within the left rectus abdominis muscle. It is suggested that the gastrointestinal symptoms should be carefully controlled in patients undergoing bone marrow transplantation.

Retinoids have anti-tumor activity in several malignant and premalignant conditions. Since Kaposi's sarcoma is regulated by steroid hormones both in vivo and in vitro, we hypothesized that retinoids may have anti-tumor effects in AIDS-related Kaposi's sarcoma. Thus, 27 patients with mucocutaneous, non-visceral AIDS-related Kaposi's sarcoma were treated with all-trans retinoic acid (tRA). Poor tolerance was observed at the initial starting dose of 150 mg/m2, and thus subsequent patients were treated using a weekly dose escalation, starting with 45 mg/m2 (given daily, in subdivided doses), to the target dose of 150 mg/m2 (given daily in three subdivided doses). Nearly half (46%) of the patients had extensive mucocutaneous disease with over 25 lesions. No patient had received prior cytotoxic chemotherapy. Ten patients had CD4 lymphocytes of 200/mm3 or greater (strata I); and 17 had under 200/mm3 CD4 lymphocytes (strata II). The median of the average daily tRA dose administered was 150 mg (90 mg/m2; there was no significant difference in the dose tolerance between the two strata). Adverse effects consisted of transient mild to moderate headaches in 65% of patients, mild to moderate skin dryness and cheilitis in 61%, and nausea and vomiting in 31%. Hematologic toxicities included hypertriglyceridemia in 62%, anemia in 23%, and neutropenia in 23%. Partial response to therapy was observed in 4/24 (17%) evaluable patients, occurring after 12, 20, 24, and 28 weeks of therapy, and lasting 4-24 weeks. Three responders had baseline CD4 lymphocyte counts < 200/mm3. Three additional patients experienced reduction in measured indicator lesions of greater than 25% but less than 50%, and seven patients experienced disease stabilization of 16 weeks or greater. In evaluable patients, the median time to disease progression was 22 weeks and the overall median survival in all patients was 27.3 months. No significant changes in CD4 lymphocyte counts, p24 antigen, and beta 2 microglobulin were observed over time. However, a statistically significant increase was observed in soluble IL-2 receptor levels while on tRA (p = 0.037). We conclude that tRA has activity in patients with mucocutaneous AIDS-related Kaposi's sarcoma with acceptable toxicity. tRA has immunological effects without upregulation of HIV parameters. Additional studies in combinations or with more active retinoids are warranted.

Taxol (paclitaxel, Bristol-Myers Squibb Company, Princeton, NJ), a drug extracted from the stem bark of the western yew, shows great promise as an antineoplastic agent for ovarian, breast, nonsmall cell lung, and head and neck cancers; melanoma; and leukemia. Although Taxol first was isolated in 1971, completion of many phase I studies was delayed until 1988, primarily because the drug caused severe hypersensitivity reactions. Other side effects of Taxol include cardiotoxicity, nausea and vomiting, diarrhea, mucositis, myelosuppression, tingling and numbness of the hands and feet, myalgia and arthralgia, alopecia, fatigue, headache, irritation at the injection site, and taste changes. Nursing care includes measures for preventing or minimizing side effects, close assessment and monitoring of potential side effects, patient education, and support. Because of the environmental impact of harvesting the western yew for Taxol, semisynthetic preparations such as taxotere are being explored.

Carboplatin is a second-generation platinum complex developed to be less ototoxic and nephrotoxic than cisplatin. The major toxicity was found to be myelosuppression; thus, it was tried in acute leukemia. When given by daily bolus injection for 5 days, carboplatin exhibited some activity but was associated with additional nonhematologic toxicity as well. When administered by continuous infusion, responses were higher and toxicity less. The Eastern Cooperative Oncology Group (ECOG) conducted a phase II study of carboplatin 315 mg/m2 daily given by continuous infusion for 5 days to adults with refractory and relapsed acute leukemia. A second course was given if the bone marrow on day 14 revealed persistent leukemia. Those achieving a complete remission (CR) were given an additional course as consolidation. The median age was 49 years among acute myelogenous leukemia (AML) patients and 46 years in acute lymphoblastic leukemia (ALL) patients. Of 46 eligible patients enrolled in the study (36 AML and 10 ALL), 8 (17%) achieved a CR (6 AML and 2 ALL). Remissions were observed in 2 of 10 primary refractory patients (1 AML and 1 ALL). When treated in first relapse, 5 of 14 patients (36%) achieved a CR. In 38 instances marrow specimens were examined after treatment; 10 (26%) showed no change, 16 (42%) were hypoplastic, and 12 (32%) were hypoplastic with residual leukemic cells. Of the 18 deaths that occurred on study, 14 were due to infection, 2 due to infection and bleeding, 1 due to uncontrolled gastrointestinal bleeding and 1 due to graft-versus-host disease in a patient who had relapsed after bone marrow transplantation. Marrow suppression was usually prolonged. Nonhematologic toxicity was mild. Gastrointestinal toxicity consisted of easily controlled nausea and vomiting. Three patients had grade 3 diarrhea. Grade 3 or more renal toxicity was observed in 8 patients, all of whom had received nephrotoxic antibiotics for treatment of bacterial or fungal infections. One patient died of renal failure that developed near the end of a second induction course. Ototoxicity was observed in 11 patients (24%) and was grade 2 or less in all but 3. These results indicate that carboplatin is an active agent in leukemia. Further studies are under way in combination with other agents such as etoposide, mitoxantrone, 5-azacytidine, and daunorubicin in treatment of acute leukemia and in combination with ifosfamide and etoposide in refractory lymphomas.

We investigated the possibility that chlorpromazine (CPZ), an antiemetic frequently used to control nausea and vomiting in cancer patients receiving chemotherapy, might modify the progression of the renal toxicity and lethality of cisplatin (CDDP). In mice the preadministration of CPZ (i.p.) 1 h prior to CDDP (i.p.) injection efficiently reduced not only the lethal toxicity, but also the renal (indicated by increased blood urea nitrogen values) and intestinal toxicity (indicated by the incidence of diarrhea) which are usually observed in mice treated with CDDP alone. To further study the apparent protective activity of CPZ against CDDP nephrotoxicity we chose rats a species more commonly used as a model for nephrotoxicity. In F344 rats, CPZ ameliorated CDDP-induced increases in blood urea nitrogen (BUN), urine glucose, protein and lactate dehydrogenase (LDH). The preadministration of CPZ had no observed effect on the antitumor activity of CDDP in mice inoculated i.p. with Sarcoma 180, EL-4 lymphoma, or P-388 leukemia cells. The present study suggest that CPZ may be of therapeutic benefit when used with CDDP. This study also provides a rational basis for the selection of antiemetic therapy.
