Abstract
We report on a lasting remission from multimodal treatment in a patient with hepatic metastasized breast cancer. After surgical removal of a singular hepatic metastasis, the patient underwent leukapheresis of peripheral blood mononuclear cell (PBMCs). For induction chemotherapy, the patient received 2 cycles of epirubicin and paclitaxel (ET). After 1 cycle of epirubicin and ifosfamide (EI), peripheral blood stem cells were harvested. After a final cycle of ET, the patient underwent high-dose chemotherapy (HDCT; thiotepa 600 mg/m/melphalan 180 mg/m) and autologous stem cell transplantation. Once reconstitution was achieved, PBMCs were reinfused followed by i.v. application of a trifunctional antibody (TrAb) with specificities anti-EpCAMxanti-CD3. TrAbs are able to simultaneously bind tumor cells, T cells, and additionally FcgammaR type I and III+accessory cells via their Fc region. Side-effects during treatment were hematotoxicity, mucositis and gastrointestinal toxicity. TrAb treatment resulted in intermittent fever, chills, elevated liver enzymes, systemic inflammatory response syndrome and pulmonary leakage. With a follow-up period of more than 8 years the patient is still in remission (96+months). This case suggests the feasibility and efficacy of combining surgery, standard and HDCT, and subsequent immunotherapy in metastatic breast cancer. Further investigation of this approach is indicated in a subgroup of patients with oligometastatic breast cancer.

Abstract
Veno-occlusive disease (VOD) is one of the most serious complications following hematopoietic stem cell transplantation (HSCT) and is associated with a high mortality. We conducted a large trial on the clinical significance of protein C (PC) and procollagen III peptide (PNPIII) levels, which have been described as possible diagnostic markers of VOD. In total, 350 patients undergoing allogeneic HSCT were included. PC and PNPIII levels were analyzed prior to conditioning and weekly until 8 weeks after the HSCT. Signs of VOD and other transplantation-related complications (graft-versus-host disease (GVHD), toxicity, microangiopathic hemolytic anemia, infection) were recorded weekly throughout the trial. Patients showed a significant drop of the PC levels in VOD (70.3 vs 96.3%, P<0.001) and with increasing severity of aGVHD. Steroids increased the PC levels (69.4% vs 109.4%, P<0.001). The highest PNPIII levels were registered in patients with VOD (mean 6.3 IU/ml). Patients with aGVHD showed an elevation of PNPIII, especially patients with hepatic aGVHD. PC levels during conditioning do not predict VOD (98.5 vs 76.5%, NS). Although PC and PNPIII may play a role in the pathogenesis of VOD they cannot discriminate between complications with jaundice and are only of limited help in the differential diagnosis of VOD.

Abstract
UNLABELLED This pilot study analyzed the efficacy and toxicity of high-dose chemotherapy (HDCT), autologous stem-cell transplantation (ASCT) and subsequent immunotherapy with T-cell reinfusion and trifunctional antibodies (trAbs) in chemotherapy-sensitive patients with metastatic breast cancer (MBC). PATIENTS AND METHODS After leukapheresis and cryopreservation of T-cells, patients received 2 cycles of induction chemotherapy ET (epirubicin/paclitaxel) and 1 cycle of El (epirubicin/ifosfamide), followed by G-CSF and stem-cell harvest. After a final cycle of ET, responders (CR/PR) underwent HDCT (thiotepa 600 mg/m2/melphalan 140-180 mg/m2) and ASCT. Once reconstitution was achieved, T-cells were reinfused, followed by application of trifunctional antibodies with specificities anti-EpCAM X anti-CD3 and anti-Her2/neu X anti-CD3. RESULTS Thirty-three patients were recruited into the study and 19, who had responded to initial chemotherapy, underwent HDCT and ASCT (4 CR, 15 PR, OR = 57.6%; 95% CI: 40-75%). Two early deaths were observed (1 toxic, 1 early progression). T-cell reinfusion and trAbs were given to 17 patients. TrAbs treatment resulted in intermittent fever, chills and elevated liver enzymes, which were seen in all patients. The median overall survival was 27.7 months (range: 5.9-82.6+). Patients who received 3 trAbs doses showed a trend towards an improved overall survival (47.2 vs. 22.4 months, p = 0.08 log rank). CONCLUSION This pilot study has shown the feasibility of combining HDCT with immunotherapy in MBC. Further investigation of this approach is indicated.

Abstract
Following allogeneic hematopoietic stem cell transplantation (HSCT) patients may have an increased bleeding tendency in spite of a normal platelet count. Moreover, an association between chronic graft-versus-host disease (cGVHD) and a thrombophilic state has been observed. Platelet receptors and granules from 27 patients following HSCT (13 without cGVHD, 14 with cGVHD) were evaluated by flow cytometric analysis and compared to 62 healthy controls. Platelets from HSCT patients stained weakly with mepacrine indicating a reduced content of dense bodies, whereas no significant degranulation reaction of alpha granules and lysosomes was detectable. In addition, a lower surface expression of GP Ia/IIa was observed, indicating an acquired thrombocytopathy. The surface receptors are activated in HSCT patients, which could be seen by the lower surface expression of GP Ib internalized during the activation process and elevated levels of LIBS-1 and PAC-1 antibody binding. Patients with cGVHD had a seven-fold increased ratio of microparticles. This study demonstrates platelet receptor and granule defects in patients following HSCT. The key role of platelets in HSCT-associated hemostatic disorders is underscored by the high levels of circulating microparticles in cGvHD patients which might explain the thrombophilic state in these patients.

Abstract
The conditioning regimen preceding hematopoietic stem cell transplantation (HSCT) causes a rapid decrease in the platelet count and signs of disseminated intravascular coagulation, possibly indicating platelet activation. As impacts during the conditioning regimen may predict later transplantation-associated complications, we investigated changes in platelet membrane glycoproteins (GP) and the liberation of microparticles. Platelet receptors and granules of 49 patients undergoing HSCT were evaluated by flow cytometric analysis before and after the different phases of the conditioning regimen [chemotherapy, total body irradiation (TBI), therapy with antithymocyte globulin (ATG)] and final transplantation. Following chemotherapy a high surface expression of CD62P, a low mepacrine staining, and a reduced surface expression of CD42b (part of the GP Ib/V/IX complex) were found, indicating an irreversible activation of platelets. In addition, elevated levels of circulating microparticles were observed, which may reinforce the thrombosis risk in these patients. Treatment with ATG leads to an elevated surface expression of PAC-1 epitopes, which are neoepitopes appearing after activation of GP IIb/IIIa. However, a significant degranulation was not detectable, which may be the consequence of inhibitory influences on platelets during ATG-induced cytokine release syndrome. TBI and transplantation itself had no influence on platelets. This study was able to demonstrate activating effects on platelets by certain phases of the conditioning regimen in patients receiving HSCT. Chemotherapy, in particular, leads to a strong and irreversible platelet activation and a generation of microparticles, which may cause an increased thrombosis risk. Our findings underline the impact of platelets on the pathogenesis of hemostatic complications during HSCT.

Abstract
Some cytokines, i.e. tumor necrosis factor-, interleukin-6 and soluble interleukin-2 receptors are associated with complications of stem cell transplantation. Insulin-like growth factors (IGFs) are a family of peptides essential for the proliferation of normal and malignant cells. Recently increased levels of IGFs have been associated with the development of malignant tumors. In this communication we report on 96 measurements of insulin-like growth factor-I (IGF-1), insulin-like growth factor-II (IGF-2), and insulin-like growth factor-binding protein-3 (IGFBP-3) performed in 19 patients following stem cell transplants. Seventeen patients had allogeneic and 2 patients autologous transplants. Most IGF determinations were made at days 0, 7, 14, 21 and 28, some at other time points. The baseline values (day 0) of IGF-1 and IGFBP-3 were not different from controls. IGF-2 values were slightly lower than controls. Following transplantation, a consistent increase of IGF-1 was observed in 9/16 patients at days 7 and 14. Later the values decreased again. IGF-2 and IGFBP-3 did not change significantly after transplantation. No direct correlation could be established with the severity of graft-versus-host disease, levels of interleukin-6 and the time to hematopoietic recovery. A potential relevance of IGFs following stem cell transplantation may be the early diagnosis of liver damage and the development of second malignancies. More studies are necessary to investigate the pathophysiology and the clinical relevance of the increase of IGF-1 following stem cell transplantation.

Abstract
Severe hepatic veno-occlusive disease (VOD) is a recognized complication of autologous and allogeneic stem cell transplantation (SCT) that is often fatal. Defibrotide (DF) is a polydeoxyribonucleotide that has been found to have anti-thrombotic, anti-ischaemic and thrombolytic properties without causing significant anticoagulation. Preliminary studies have demonstrated activity for DF in the treatment of VOD, with minimal associated toxicity. In the present study, 40 patients who fulfilled established criteria for VOD were treated with DF on compassionate grounds in 19 European centres; 28 patients met risk criteria predicting progression of VOD and fatality or had evidence of multiorgan failure (MOF), and were defined as 'poor-risk'. DF was commenced intravenously at a median of 14 d (range, -2 d to 53 d) post SCT at doses ranging from 10 to 40 mg/kg. The median duration of therapy was 18 d (range, 2--71 d). Twenty-two patients showed a complete response (CR) (bilirubin < 34.2 micromol/l and resolution of signs/symptoms of VOD and end-organ dysfunction) [CR = 55%, confidence interval (CI) 40--70%] and 17 patients (43%) are alive beyond d +100. Ten poor-risk patients showed a complete response (CR = 36%, CI 21--51%). These results demonstrate that DF is an active treatment for VOD following SCT and a randomized trial is now underway in order to further evaluate its role.

Abstract
Hepatic veno-occlusive disease (VOD) is the third most important fatal complication in allogeneic bone marrow transplantation (BMT), the second most significant one in the autologous setting and the most severe of all the regimen related toxicities. A growing number of VOD cases has to be expected due to the increasing number of high dose chemotherapies given with consecutive stem cell transplantation in patients with solid tumors. Confirmation of the diagnosis of VOD by biopsy is associated with a high risk of severe bleeding complications and, unfortunately, until now reliable laboratory markers have not as yet been established. Recently, plasminogen activator inhibitor 1 (PAI-1), the main inhibitor of the fibrinolytic system, has been found to be significantly elevated in VOD patients probably reflecting hypofibrinolysis in these patients. Furthermore, PAI-1 was able to distinguish between patients with VOD and those with hyperbilirubinemia after BMT caused by graft-versus-host-disease (GVHD) or toxic effects, in which cases the PAI-1 levels were mostly within the normal range. In this overview we summarize the data strongly indicating that PAI-1 is a useful marker for the diagnosis of VOD and helps in the differential diagnosis of hyperbilirubinemia after BMT.

Abstract
Thrombotic complications are observed in patients undergoing bone marrow transplantation despite thrombocytopenia and impaired coagulation due to liver function disturbances. Endothelial cell damage which is involved in the pathogenesis of major transplant related complications like graft-versus-host disease, veno-occlusive disease, sepsis or microangiopathy may be a contributing factor. Little is known about platelet function in bone marrow transplant recipients. In order to study functional alterations in circulating platelets we investigated unstimulated and ADP-stimulated platelets of 10 bone marrow transplant recipients ex vivo by flow cytometry in a pilot study using a panel of monoclonal antibodies to characterize changes in membrane glycoproteins. Samples were collected before and during conditioning and at three timepoints after engraftment. 10 healthy volunteers served as controls. Platelets of bone marrow transplant recipients showed partly a significant, higher expression of surface bound fibrinogen, activated fibrinogen receptor, and glycoprotein Ib as compared to controls. P-selectin, a marker of platelet degranulation was significantly elevated after ADP-induced stimulation at all timepoints compared to controls. Only marginal differences were found for GP IIb/IIIa surface expression. The data point to an increased platelet activation state in bone marrow transplant recipients which might contribute to the thrombotic phenomena observed in these patients.

Abstract
To investigate endothelial cell alterations in BMT recipients developing acute graft-versus-host disease (aGVHD) we determined levels of the endothelial cell markers von Willebrand factor (VWF) and thrombomodulin (TM) in 57 patients undergoing BMT. Before conditioning VWF and TM levels did not differ significantly between transplant recipients who later developed no or mild (grade I) aGVHD (group A, allogeneic n = 22, autologous n = 7; VWF 136.0 +/- 44.1%; TM 29.5 +/- 18.0 ng/ml), and those with moderate or severe (grade II or III) aGVHD (group B, n = 28; VWF 142.2 +/- 37.6%; TM 35.2 +/- 20.1 ng/ml). A first significant rise of both VWF and TM level was noted after conditioning (day 0) both in group A (VWF 197.0 +/- 113.3%; P < 0.001; TM 39.3 +/- 23.3 ng/ml; P < 0.01) as well as in group B (VWF 201.7 +/- 53.3%; P < 0.0001; TM 43.5 +/- 23.5 ng/ml; P < 0.05). Subgroup analysis of autografted patients revealed no significant increase after conditioning in these patients. At the time of engraftment and onset of aGVHD (day 21), when VWF and TM levels within the groups were significantly elevated as compared with baseline (day -8) levels, group B patients (62.7 +/- 38.5 ng/ml) had significantly higher (P < 0.01) TM levels than patients of group A (37.4 +/- 19.6 ng/ml). This significant elevation also persisted at the end of the investigational period (day 28; group B: 56.0 +/- 37.6 ng/ml; group A: 38.2 +/- 23.7 ng/ml; P < 0.01). An elevation of endothelial cell markers is found in the course of BMT, particularly after conditioning and at the time of engraftment. This increase is pronounced in patients with aGVHD suggesting not only epithelial cell but also endothelial cell injury during aGVHD.

Abstract
Hepatic veno-occlusive disease (VOD) is a frequent and severe complication after bone marrow transplantation (BMT). We previously have described plasminogen activator inhibitor-1 (PAI-1) as a possible marker of VOD. To confirm the significance of this finding, we now determined PAI-1 levels in 31 of 186 consecutive patients undergoing BMT who developed hyperbilirubinemia greater than 3 mg/dL for various reasons. Diagnoses were made by clinical criteria and confirmed by biopsy in 23 of 31 patients. They included VOD (n = 7), acute graft-versus-host disease (GVHD) of the liver (n = 7), and other hepatic injury (n = 17). PAI-1 (mean +/- SD) was significantly (P < .001) elevated in patients with VOD (321.6 +/- 161.2 ng/mL) as compared with patients with GVHD (22.8 +/- 8.4 ng/mL) or other hepatic damage (32.8 +/- 30.8 ng/mL) at the timepoint of bilirubin increase. At the peak bilirubin concentration, the corresponding PAI-1 levels were 426.1 +/- 230.0 ng/mL in patients with VOD, 41.0 +/- 20.6 ng/ mL in patients with GVHD, and 44.6 +/- 32.9 ng/mL in patients with other hepatic injury (P < .001 VOD v GVHD/other hepatic injury). Our results underline the relevance of PAI-1 in the differential diagnosis of hyperbilirubinemia after BMT and its significance as a sensitive and specific marker of severe VOD.

Abstract
Plasminogen activator inhibitor 1 (PAI-1) and amino-propeptide of type III procollagen (PIIINP) have been described as markers of hepatic veno-occlusive disease (VOD) after bone marrow transplantation (BMT). We determined these parameters in two patients undergoing BMT and subsequent liver transplantation due to VOD. Previously normal PAI-1 levels (maximum 30.0 ng/ml in patient 1, 23.7 ng/ml in patient 2) were elevated for the first time in both patients at the time of clinically diagnosed VOD on days 40 and 20, respectively (patient 1: 317.5 ng/ml; patient 2: 317.2 ng/ml). Levels remained elevated until liver transplantation was performed on days 79 and 41, respectively. Baseline levels (day -8) of aminopropeptide of type III collagen (patient 1: 4.44 microg/l; patient 2: 8.1 microg/l) peaked at the time of BMT in both patients (155.0 microg/l and 108.3 microg/l). After an intermittent decrease at the time of discharge on day 32, a second elevation was observed in patient 1 when she was readmitted and presented with typical signs of VOD on day 40. In patient 2, PIIINP levels remained high until VOD was diagnosed (day 20) and liver transplantation was performed. After liver transplantation, PAI-1 levels normalized in both patients and PIIINP levels declined. Both patients died due to infectious complications and multiorgan failure on days 141 and 101, respectively. Whereas the early rise of PIIINP did not correlate with the clinical onset of VOD, the results emphasise the relevance of PAI-1 for diagnosing VOD.

Abstract
Veno-occlusive disease (VOD) of the liver is one of the most frequent fatal complications after bone marrow transplantation (BMT). A decrease of natural anticoagulants, in particular protein C (PC), has been assumed to be involved in the pathogenesis of the disease. We determined PC and antithrombin III (AT III) levels in two patients undergoing BMT and subsequent liver transplantation due to VOD. Additionally, in one of the patients protein S (PS) levels were also measured. Normal baseline (day-8) PC levels (86 and 89%) were markedly reduced in both patients at the time of VOD manifestation on day 20 and 40, respectively (26 and 31%). PS levels lay within the normal range from day-8 (before myeloablative chemotherapy) until one week after clinical onset of VOD when substitution therapy with fresh frozen plasma (FFP) was initiated. AT III levels decreased moderately during the second and third posttransplant week, but were normal in the patient with a late clinical manifestation of VOD. In both patients PC and PS levels lay within the normal range after liver transplantation which was performed on day 41 and 79, respectively. AT III was substituted several times. Both patients died due to infectious complications on day 141 and 101, respectively. The data confirm previous reports that a decrease of PC is observed in BMT recipients and can be associated with hepatic vein occlusion. Whereas the relevance of AT III is uncertain, PS does not seem to be involved in the pathogenesis of VOD. Liver transplantation lead to normalization of PC levels, but its significance remains to be discussed in terms of ethical justifiability, medical feasibility and costs.

Abstract
Tumor necrosis factor-alpha (TNF alpha) is a central mediator in the pathogenesis of sepsis. It also interferes with the hemostatic system and exerts and a net procoagulant effect. Since TNF alpha may contribute to thrombotic complications in sepsis patients, we determined markers of thrombin activation, parameters of the fibrinolytic system (D-dimer, tissue plasminogen activator antigen (tPA) urinary type plasminogen activator antigen (uPA), plasminogen activator inhibitor antigen (PAI-1) and von Willebrand factor antigen (vWF) in 30 patients with sepsis or septic shock. All patients were treated with standard therapy, but 14 patients were treated additionally with an anti-TNF alpha monoclonal antibody (MAK 195F); 16 patients served as historical controls. No significant effect of the antibody on the parameters of the hemostatic system could be determined. Our data speak against a modulation of coagulation or the fibrinolytic system by the monoclonal anti-TNF alpha antibody MAK 195F in this cohort of sepsis patients.
