Clinical predictors of survival in patients with castration-resistant prostate cancer receiving sipuleucel-T cellular immunotherapy. Cancer Chemother Pharmacol 2017; 80:583-589. [PMID: 28730293 DOI: 10.1007/s00280-017-3391-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2017] [Accepted: 07/10/2017] [Indexed: 01/31/2023]
Abstract
BACKGROUND We evaluated the patterns of progression and determined clinical predictors of survival in patients with castration-resistant prostate cancer (CRPCa) who received sipuleucel-T. METHODS We retrospectively analyzed 56 consecutive patients with asymptomatic or minimally symptomatic CRPCa treated with sipuleucel-T. Age, number of bone metastases, history of prior systemic treatment, and alkaline phosphatase level (ALP) were tested as predictors of survival in a multivariate Cox proportional hazards regression model. The Kaplan-Meier method was used to estimate event-free probabilities. RESULTS The 56 patients were a median age of 67 years (range 51-84 years). After sipuleucel-T treatment, 25 patients developed bone progression after a median of 22 months of follow-up (54% of patients were event free at 2 years) and 10% (6/56 patients) developed rapid progression. Eleven deaths were observed after a median of 28 months of follow-up. Forty-eight patients were included in the multivariate analysis for overall survival. The analysis showed that age >70 years (p = 0.012), number of bone metastases >20 (p = 0.018), prior systemic treatment (p = 0.018), and ALP level >90 IU/L (p = 0.010) significantly predicted worse overall survival. Two-year overall survival was 36% among the 16 patients with two or more of these factors and was 93% among the 32 patients with one or none of these factors (p = 0.0004). CONCLUSIONS CRPCa patients with age (>70 years), increased tumor burden in bone (>20 metastases and/or elevated ALP level), and/or prior systemic treatment are more likely to experience rapid deterioration after sipuleucel-T. These results need to be prospectively validated.

Abstract
The bone marrow niche functions are modulated by complicated cytokines network. The aim of our study was to evaluate the levels of VCAM-1, VEGF, MMP-9 and SDF during mobilization of CD34+ cells in patients with hematological malignancies. Thirty four patients were enrolled to the study (19F, 15 M) at median age of 57 years. The group consisted of patients with multiple myeloma (26) and lymphoma (8). The mobilization procedures comprised chemotherapy and then G-CSF. Blood samples were collected before chemotherapy (N = 34) and on the day of the first apheresis (N = 26). Cytokines were evaluated with ELISA assay. We observed significant increase in VCAM-1 levels during mobilization. On contrary, VEGF and SDF levels decreased during mobilization procedure. The levels of MMP-9 were stable during mobilization. We divided patients according to baseline cytokines levels below and above median into "low" and "high" expressors. The group of VEGF "low" expressors had longer median time of G-CSF treatment before first apheresis than 'high' expressors. Baseline VEGF levels correlated adversely with duration of G-CSF treatment before first apheresis. Patients were also divided according to median cytokines levels at apheresis into "low" and "high" expressors. "High" VCAM-1 expressors had higher CD34+in peripheral blood as well as higher CD34+numbers collected during first apheresis than "low" expressors. In conclusion, the levels of niche cytokines change significantly during mobilization in patients with hematopoietic malignancies. Baseline VEGF can influence timing of mobilization. Higher VCAM-1 corresponds with higher mobilization efficacy.

Abstract
We previously reported an increased incidence of thrombotic toxicities in Sprague-Dawley rats administered the highest dose level of a hyperglycosylated analog of recombinant human erythropoietin (AMG 114) for 1 month as not solely dependent on high hematocrit (HCT). Thereafter, we identified increased erythropoiesis as a prothrombotic risk factor increased in the AMG 114 high-dose group with thrombotic toxicities, compared to a low-dose group with no toxicities but similar HCT. Here, we identified pleiotropic cytokines as prothrombotic factors associated with AMG 114 dose level. Before a high HCT was achieved, rats in the AMG 114 high, but not the low-dose group, had imbalanced hemostasis (increased von Willebrand factor and prothrombin time, decreased antithrombin III) coexistent with cytokines implicated in thrombosis: monocyte chemotactic protein 1 (MCP-1), MCP-3, tissue inhibitor of metalloproteinases 1, macrophage inhibitory protein-2, oncostatin M, T-cell-specific protein, stem cell factor, vascular endothelial growth factor, and interleukin-11. While no unique pathway to erythropoiesis stimulating agent-related thrombosis was identified, cytokines associated with increased erythropoiesis contributed to a prothrombotic intravascular environment in the AMG 114 high-dose group, but not in lower dose groups with a similar high HCT.

Abstract
BACKGROUND Peripheral blood stem cells are an important source of hematopoietic stem cells (HSCs) for allogeneic transplantations. Some allogeneic donors mobilize HSCs poorly in response to the granulocyte--colony-stimulating factor (G-CSF). The estimation of the mobilization result in an individual donor is difficult due to the absence of suitable predictive factors. STUDY DESIGN AND METHODS We analyzed the concentrations and kinetics of certain cytokines induced by G-CSF in 76 healthy donors and compared them with the mobilization efficiency. RESULTS The levels of the most cytokines increased after the G-CSF application: sICAM, sVCAM, MMP-9, interleukin (IL)-6, TNF-α, sE-selectin, and fibronectin. The concentrations of SDF-1α and IL-8 decreased and VEGF and fractalkine remained unchanged. The premobilization concentrations of IL-6 (p = 0.0093) and TNF-a (p = 0.0006) correlated with preapheresis CD34+ cell count. The comparison of premobilization cytokine levels between better and worse mobilizers showed a difference for TNF-α (p = 0.0006) and IL-6 (p = 0.0682). The TNF-α level below cutoff of 3.6 pg/mL implied approximately 20 times higher risk of poor mobilization (odds ratio, 19.9; p = 0.0002). The immunophenotyping of CD34+ cells suggested a negative correlation between Day +5 CD34+ count and expression of CD11a (p = 0.0319) and a positive correlation with CD44 antigen expression (p = 0.0096). CONCLUSION The concentrations of certain cytokines corresponded to the quality of HSC mobilization in healthy donors. Their levels measured before mobilization could probably serve as predictive factors for mobilization efficacy and prospectively detect donors who might profit from new mobilization molecules.

Abstract
Soluble forms of some cell adhesion molecules (CAM), sICAM-1, sVCAM-1, and sE-selectin, are elevated in the sera and plasma of patients with inflammation, arthritis, diabetes, and cancer. Increased levels of these soluble molecules in patients with cancer have been shown to correlate with disease progression and survival. This suggests that increased expression of the soluble forms of CAMs may play an important role in cancer cell growth and metastasis and may be prognostic and/or predictive of malignant disease. In this retrospective study, we assessed the clinical significance of sICAM-1, sVCAM-1, and sE-selectin in 95 patients with metastatic breast cancer enrolled in clinical trials of high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT). The significance of soluble HER-2 (sHER-2) and sFAS status, determined in previous studies for this group of patients, was also included in this analysis. Univariate analysis showed that sICAM-1, sVCAM-1, sFas, sHER-2 positive status, and the presence of liver metastases were significant prognostic factors for both progression-free survival (PFS) and overall survival (OS) in the total patient group. In multivariable analysis, HER-2 and sFAS were shown to be independent prognostic factors for PFS and OS. Within the various treatment groups examined, sICAM-1 was a prognostic factor for clinical outcome for patients with metastatic breast cancer enrolled in trials with cyclophosphamide- and carboplatin-based or vinblastine-based HDC, but not in trials with paclitaxeland cyclophosphamide-based HDC.

Abstract
Abstract
Idiopathic myelofibrosis (IM) is characterized by increased numbers of CD34+ cells in the peripheral blood (PB). We explored the possible mechanisms underlying this abnormal trafficking of CD34+ cells. Plasma levels of neutrophil elastase (NE), total and active matrix metalloproteinase 9 (MMP-9), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were dramatically increased in IM. The absolute number of CD34+ cells in the PB was correlated with the levels of sVCAM-1. Marked elevations of the levels of NE but not total and active MMP-9 as well as MMP-2 were detected in media conditioned by IM mononuclear cells (MNCs) as compared with that of healthy volunteers. IM MNC-conditioned media, however, was shown by zymographic analysis to contain increased gelatinolytic activity corresponding to the molecular weight of MMP-9. IM MNC-conditioned media also exhibited a greater ability to cleave VCAM-1 and c-kit in vitro, consistent with the biologic actions of NE. In addition, the increased ability of IM PB CD34+ cells to migrate through a reconstituted basement membrane was diminished by several inhibitors of MMP-9 activity, indicating that these cells express increased levels of this MMP. These data indicate that a proteolytic environment exists in IM which might result in the sustained mobilization of CD34+ cells.

Abstract
Sickle cell patients are characterized by stress erythropoiesis involving cytokines, growth factors, and adhesion molecules. We set out to determine whether serum soluble vascular cell adhesion molecule-1 (sVCAM-1) levels, which are inversely related to red blood cell counts in sickle cell disease (SCD), reflect erythropoietic activity in adult HbSS patients. Serum levels of sVCAM-1 were compared to erythropoietin (EPO), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-3 (IL-3), and soluble transferrin receptor (sTfR) levels in 29 adults with HbSS, and their respective levels were also compared to 29 race- and age-matched HbAA controls. EPO and sTfR levels were increased as compared to healthy controls, whereas IL-3 and GM-CSF were not. No significant correlation of sVCAM-1 levels could be detected with any of the measured erythropoietic markers. Patients, but not controls, with detectable IL-3 levels had lower sTfR and GM-CSF levels as compared to patients with undetectable IL-3 levels. Even though a link of sVCAM-1 to erythropoiesis could not be established, it cannot be ruled out that sVCAM-1 levels reflect the release of young red blood cells into the circulation. IL-3 and GM-CSF levels suggest that different rates of erythropoiesis may be characterized by specific cytokine profiles in SCD. Further research should focus on the potential cytokines and adhesion molecules involved in sickle cell erythropoiesis, as this may increase our understanding of sickle cell complications and may provide us with potential markers for risk assessment in sickle cell disease as well.

Abstract
Cytokines and adhesion molecules play an important role in the pathophysiology of vaso-occlusion in sickle cell disease (SCD), and their in vivo profiles are potential tools for assessing SCD severity. We compared steady-state soluble vascular cell adhesion molecule-1 (sVCAM-1) serum levels to clinical (painful crisis frequency, occurrence of acute chest syndrome, leg ulcers, and cerebrovascular disease) and related hematological parameters of SCD severity (such as HbF%, hemoglobin levels, and leukocyte counts) in 29 HbSS adults. Serum sVCAM-1 levels were not related to clinical severity, but an inverse correlation was demonstrated between sVCAM-1 and hemoglobin levels (r=-0.71, p<0.001) with a positive correlation to serum lactate dehydrogenase levels (r=0.59, p=0.008). Based upon these results, steady-state serum sVCAM-1 levels do not seem to reflect clinical disease severity. However, as VCAM-1 is involved in hematopoiesis, sVCAM-1 levels might reflect bone marrow activity in SCD. This underlies the pleiotropic nature of adhesion molecules in vivo and the need for further research in this area, especially since therapies targeting (cellular) adhesive interactions involving the endothelium are emerging for SCD.

Abstract
BACKGROUND There is compelling evidence that hemopoietic precursor cells (HPC) play a crucial role in establishing cellular inflammation in allergic diseases. Increased levels of circulating CD34+ HPC committed to the myeloid lineage have been extensively reported in allergic rhinitis, asthma and eczema, whereas CD34+ cells have been identified within the cellular infiltrates of tissues, at peripheral sites of inflammation. METHOD We conducted a pilot study to evaluate CD34+ traffic in the peripheral blood of 22 consecutive patients (13 men and nine women; mean age 28.9 years), independently of treatment. The patients presented rhinitis, asthma, eczema, urticaria and adverse food reactions of suspected allergic origin. Allergic reactions were extrinsic in 18 patients and intrinsic in four. In 12 patients who underwent sublingual specific immunotherapy, CD34+ cells were quantified at enrollment (T0), one year later (T1) and two years later (T2). The severity of symptoms was graded on a five-point scale (0 = absence of symptoms and 4 = severe symptoms). Twenty healthy human subjects (10 men and 10 women; mean age 24.5 years) were evaluated as controls. To obtain information about the total amount of circulating HPC, independently of the lineage commitment (Lin+/-) and the degree of differentiation (CD34bright/dim), we used a modification of the Milan protocol of peripheral blood CD34+ cell estimation. The cells were analyzed using a BD FACScan or FACSCalibur and the results were expressed as the percentage of positive cells. RESULTS CD34+ cell traffic in the control group was very low since all values were < 0.10 (median value: 0.03 %). Values in the patient group were increased in both extrinsic and intrinsic forms with a median value of 0.25 % (interquartile range: 0.13- 0.33 %). The relationship between CD34+ traffic and the severity score was highly significant (Spearman's rho = 0.954; test of Ho: CD34; independent score: Pr > t = 0.000). CONCLUSIONS The data reported herein suggest that the method employed is effective in assessing acute allergic inflammation, as well as minimal persistent inflammation underlying an asymptomatic clinical condition. Evaluation of CD34bright/dim peripheral traffic, if confirmed by the outcomes of a multicenter study currently being planned together with traditional study of circulating IgE, could be a reliable non-invasive laboratory tool for monitoring allergic inflammation.
