Autologous graft-versus-host disease induction in advanced breast cancer: role of peripheral blood progenitor cells.

The purpose of the present study was to investigate the impact of the use of peripheral blood progenitor cells (PBPCs) on the induction of autologous graft-versus-host disease (GVHD) in patients with advanced breast cancer. 14 women with stage IIIB and 36 women with stage IV breast cancer received cyclosporine (CsA) 2.5 mg kg-1 i.v. daily, d 0-28, and interferon-gamma (IFNg) 0.025 mg/m2 s.c. qod, d7-28, following PBPC-T +/- bone marrow transplantation (BMT). Preceding high-dose chemotherapy consisted of cyclophosphamide 6 g/m2 and thiotepa 800 mg/m2. Histologically proven > or = grade II cutaneous GVHD was induced in18/50 (36%) of patients and was independent of the source of haematopoietic support. In vitro studies showed that post-transplant, 76% of patients had developed auto-cytotoxicity against their own pre-transplant PHA-lymphoblasts. A significant correlation between the occurrence of GVHD > or = grade II and cytolysis was observed in the NK cell-line K562 and the T47D breast cancer cell-line. With a median follow-up of 2(1/2) years, the overall survival (OS) is 58%, the disease-free survival (DFS) 26%, both independent of the development of GVHD and similar to what has been observed in other studies on high-dose chemotherapy in advanced breast cancer. It therefore remains unclear whether the induction of autologous GVHD with the occurrence of auto-cytotoxic lymphocytes can result in an anti-tumour effect in this group of patients.

The effectiveness of the comprehensive coping strategy program on clinical outcomes in breast cancer autologous bone marrow transplantation.

Patients with breast cancer who undergo autologous bone marrow/peripheral blood stem cell transplantation (ABMT) cope not only with a life-threatening medical treatment, but also with multiple, interrelated symptoms including pain, fatigue, psychological distress, and nausea. The purpose of this study was to determine, in a randomized controlled clinical trial, whether a comprehensive coping strategy program (CCSP) was effective in significantly reducing pain, fatigue, psychological distress, and nausea in patients with breast cancer who underwent ABMT. The CCSP was composed of preparatory information, cognitive restructuring, and relaxation with guided imagery. Randomization placed 52 patients in the CCSP treatment group and 58 patients in the control group. The CCSP was found to be effective in significantly reducing nausea as well as nausea combined with fatigue 7 days after the ABMT when the side effects of treatment were most severe. These results are important given the high incidence of nausea and fatigue in the ABMT population. The CCSP-treated group experienced mild anxiety as compared with the control group who reported moderate anxiety. The greatest effectiveness of CCSP may correspond to the time of the greatest morbidity for patients with breast cancer who have undergone ABM.

Pain, psychological distress, health status, and coping in patients with breast cancer scheduled for autotransplantation.

PURPOSE/OBJECTIVES: To describe pain, psychological distress, health status, and coping that patients with breast cancer who were scheduled for autotransplantation experienced; the strength and direction of relationships among pain, psychological distress, health status, and coping; and the percentage of variance within the concept of health status that age, pain, psychological distress, and coping. DESIGN: Descriptive, correlational. SETTING: An urban, National Cancer Institute-designated comprehensive cancer center located in the eastern United States. SAMPLE: A convenience sample of 83 female patients with breast cancer scheduled for autotransplantation. The population age ranged from 22-59 years (X = 44.47 years) and was comprised of 72 (88%) Caucasians, 6 (7%) African Americans, and 4 (5%) from other minorities. METHODS: An oncology clinical nurse specialist in the outpatient medical oncology clinic collected the data during a regularly scheduled visit approximately 20 days prehospitalization for high-dose chemotherapy and autotransplantation. Data were collected using a demographic data from and self-report instruments (Gaston-Johansson Painometer, State-Trait Anxiety Inventory, Beck Depression Inventory, Medical Outcomes Study Short-Form General Health Survey, and Coping Strategies Questionnaire). MAIN RESEARCH VARIABLES: Pain, psychological distress, health status, and coping. FINDINGS: Although the subjects experienced low pain intensity, the range of reported pain intensity ratings was wide. Pain locations varied but were reported mainly in the vagina, chest, shoulder, and arm. Although subjects reported primarily mild depression and mild state anxiety, the range of depression and state anxiety scores was wide. Coping strategies used most frequently to deal with pain included positive coping statements, diverting attention, praying and hoping, increasing activity level, and ability to control and decrease pain. Subjects reported moderate total health status and low role functioning. Moderate, positive correlations were seen between state anxiety and depression and physical functioning and role functioning. Sixty-five percent of the variance in health status was explained by sensory pain depression, and catastrophizing. CONCLUSIONS: Patients with breast cancer who are scheduled for autotransplantation may experience pain, psychological distress, and alterations in coping and perceived health status. Total pain intensity, sensory pain, depression, and catastrophizing appear to be important variables related to the patient's perceived health status. IMPLICATIONS FOR NURSING PRACTICE: Oncology nurses need to include assessment of pain, psychological distress, health status, and coping in their routine patient assessment prior to autotransplantation to provide appropriate care and make necessary multidisciplinary referrals. Future nursing research should be directed toward the implementation and evaluation of interventions that promote the use of comprehensive coping strategies to decrease pain, anxiety, and depression.

Randomized, double-blind comparison of a prochlorperazine-based versus a metoclopramide-based antiemetic regimen in patients undergoing autologous bone marrow transplantation.

BACKGROUND: Highly emetogenic combination alkylator therapy is routinely used in autologous bone marrow transplantation for treatment of eligible patients with solid tumors. Antiemetic therapy remains less than optimal in this setting. METHODS: One hundred twenty-six patients with cancer receiving high dose cisplatin, cyclophosphamide, and carmustine with autologous bone marrow support were randomized to receive one of four double-blinded antiemetic regimens: 4-day continuous infusion prochlorperazine (6 mg/m2 intravenous [i.v.] loading dose followed by 1.5 mg/m2/hour) or metoclopramide (80 mg/m2 iv loading dose followed by 20 mg/m2/hr) each with either dronabinol 5 mg/m2 or placebo capsules for two doses before carmustine on the last day of chemotherapy. All subjects received scheduled lorazepam and diphenhydramine throughout the 4-day study period. Efficacy was measured by the Emetic Process Rating Scale and the Rhodes Index of Nausea and Vomiting (INV) Form 2. RESULTS: One hundred six patients completed the study and were fully evaluable. The median number of emetic episodes on the metoclopramide study arm were: 1 (0-7, day -6), 1 (0-6, day -5), 2 (0-9, day -4), and 2 (0-10, with dronabinol day -3) or 2 (0-7, no dronabinol day -3) and on the prochlorperazine study arm were: 4 (0-12, day -6), 0 (0-8, day -5), 0 (0-12, day -4) and 2.5 (0-9, with dronabinol day -3) or 2 (0-12, no dronabinol day -3). Metoclopramide was significantly better on the first day of therapy (day -6, P < .002) and prochlorperazine was significantly better on the third day of therapy (day -4, P < 0.002). There was no significant difference among any of the four arms on the last day of chemotherapy (day -3), or when the median number of emetic episodes over the total study period were compared. The patients' assessment of nausea, vomiting, and retching on the INV Form 2 was consistent with the observer ratings. Toxicities requiring dose reduction or discontinuation of antiemetic drugs included diarrhea, cardiac arrhythmias, sedation, anxiety, and akathisia. CONCLUSIONS: Both metoclopramide and prochlorperazine in combination with lorazepam and diphenhydramine offer good control of nausea and vomiting although the sedation and low risk for cardiac toxicity limit the regimen to an inpatient setting with close monitoring. No regimen was clearly superior during the entire treatment period but prochlorperazine offered more consistent control after the first day.

Phase I and pharmacologic study of the alkylating agent modulator novobiocin in combination with high-dose chemotherapy for the treatment of metastatic breast cancer.

PURPOSE: Resistance to alkylators may potentially be overcome by drugs that inhibits DNA repair, thus improving the efficacy of high-dose chemotherapy. This trial was performed to determine if novobiocin, an agent that inhibits DNA repair, could be given with high-dose alkylators. Study aims were to define the toxicities and maximal-tolerated dose (MTD) of novobiocin and the pharmacokinetics of novobiocin and high-dose cyclophosphamide and thiotepa. PATIENTS AND METHODS: Thirty-eight women with responsive metastatic breast cancer received high-dose cyclophosphamide (3 to 6 g/m2 over 4 days), thiotepa (400 to 800 mg/m2), and novobiocin (0.5 to 5.0 g/d x 7, orally) with autologous marrow support. Toxicity was monitored. The pharmacology of novobiocin, cyclophosphamide, and thiotepa was evaluated. RESULTS: There were no toxic deaths. The MTD of novobiocin was 4 g/d. All seven patients treated at 5 g/d developed grade III/IV mucositis and vomiting. The severity of mucositis correlated with the plasma levels of novobiocin. Other severe toxicities were not observed. Plasma novobiocin levels > or = 100 micrograms/mL, which are associated with reversal of drug resistance in animal models, were consistently seen at dose levels greater than 2 g. The dispositions of cyclophosphamide and thiotepa were not altered by novobiocin. CONCLUSION: Novobiocin may be given with high-dose alkylators in doses that produce plasma levels that augment the activity of these cytotoxics in experimental models. The pharmacology of high-dose cyclophosphamide and thiotepa is unaffected. Novobiocin 4 g/d orally for 7 days is recommended for future study.

Predictive factors for peripheral-blood progenitor-cell collections using a single large-volume leukapheresis after cyclophosphamide and granulocyte-macrophage colony-stimulating factor mobilization.

PURPOSE: (1) To study the ability of mobilized peripheral-blood progenitor cells (PBPC) collected in a single large-volume leukapheresis performed on a predetermined date to accelerate engraftment after high-dose cyclophosphamide and thiotepa; (2) to establish the minimum dose of PBPC associated with early engraftment; and (3) to identify parameters predictive of collection of large numbers of PBPC. PATIENTS AND METHODS: Twenty-three patients with breast cancer received cyclophosphamide (4 g/m2) and granulocyte-macrophage colony-stimulating factor ([GM-CSF] 5 micrograms/kg/d x 15 days) for PBPC mobilization. A single leukapheresis was performed 15 days after cyclophosphamide administration. Then, patients received high-dose cyclophosphamide and thiotepa followed by reinfusion of PBPC and 4-hydroperoxycyclophosphamide (4HC)-purged bone marrow. PBPC concentration was measured in serial peripheral-blood samples and in the leukapheresis product. Correlation analysis between PBPC dose and engraftment and between leukapheresis yield and patient characteristics was attempted. RESULTS: A single leukapheresis processed a median 36 L (range, 24 to 46) blood and collected 5 x 10(6) CD34+ cells/kg (< 0.3 to 24) and 6.2 x 10(5) colony-forming units granulocyte-macrophage (CFU-GM)/kg (< 0.001 to 29). All sixteen patients (70%) reinfused with > or = 2.9 x 10(6) CD34+ cells/kg reached a level of greater than 1,000 leukocytes/microL by day 13 and greater than 50,000 platelets/microL by day 15. All of these patients had a percentage of peripheral-blood CD34+ cells > or = 0.5%, and all but one, a level of greater than 100,000 platelets/microL, on the day of leukapheresis. The bone marrow CD34+ cell percentage at study entry predicted the number of CD34+ cells collected after PBPC mobilization (R2 = .42, P = .002). All patients with > or = 2.5% bone marrow CD34+ cells experienced early engraftment. CONCLUSION: Reinfusion of PBPC collected in a single leukapheresis accelerates engraftment in the majority of patients. Pretreatment bone marrow CD34+ cell content determines PBPC mobilization capacity and may help select hematopoietic rescue strategies.

Administration of human recombinant granulocyte colony-stimulating factor (filgrastim) accelerates granulocyte recovery following high-dose chemotherapy and autologous marrow transplantation with 4-hydroperoxycyclophosphamide-purged marrow in women with metastatic breast cancer.

Stem cell contamination by tumor is common in many diseases for which autologous bone marrow transplantation is used. In in vitro models chemotherapeutic purging reduces contamination and may have an impact on clinical outcome. Purging, however, delays engraftment. Little is known about the ability of granulocyte colony-stimulating factor (G-CSF) to accelerate myelopoiesis after purged autologous bone marrow transplantation. We treated 22 women with metastatic breast cancer with high-dose cyclophosphamide and thiotepa and, following the infusion of 4-hydroperoxycyclophosphamide-purged marrow, administered G-CSF, 16 micrograms/kg daily, from day 0 to engraftment. Results were compared with a control population of 24 women with breast cancer who received identical chemotherapy and purged marrow but not growth factor. Neutrophil recovery was accelerated in the G-CSF-treated population. An absolute neutrophil count of 500 was reached in 19 days compared with 29 for the historic controls. The median number of days febrile was reduced (8 versus 5.5) as were the number of days of hospitalization from marrow infusion (33 versus 25). There was no difference in the number of days on antibiotics or time to last platelet transfusion. G-CSF was administered without any notable toxicity. G-CSF accelerates myelopoiesis following the infusion of 4-hydroperoxycyclophosphamide-purged autologous marrow and shortens hospitalization.

The neurons of the first synaptic region of the optic neuropil of the firefly, Phausis splendidula l. (Coleoptera).

On the basis of Golgi preparations the neuronal elements of the lamina ganglionaris (first synaptic region of the visual system) of the firefly. Phausis splendidula L., are described. Of the set of 8 retinula fibres that originate from each ommatidium of the compound eye, at least 6 terminate in the esternal plexiform layer. At least one, probably two, retinula fibres per ommatidium penetrate this layer to end in the medulla, via the first optic chiasma. Five types (m1-m5) of monopolar cells can be distinguished. Only two of these, m1 and m3 have dendritic fields limited to one column of the lamina mosaic; all other monopolar cells have larger fields of up to 45 mum diameter. m2 and m4 have various field spreads in different strata of the external plexiform layer. m5 has process in only one stratum of the external plexiform layer. Medulla-to-lamina cells with arborisations associated with only a single column of the lamina mosaic were not observed; medulla-to-lamina cells whose fields coincide with the various strata of the external plexiform layer were found, however. The present observations are briefly compared with those made on another beetle, Hoplia farinosa L. Comparisons with other species of insects, and the relationship between structure of the eye and structure of the lamina are also discussed.
