Erythropoietin for the treatment of anemia of malignancy associated with neoplastic bone marrow infiltration.

1990

This clinical trial was performed to study the effects of intravenously (IV) administered recombinant human (rh) erythropoietin (EPO) at escalating doses (150, 300, and 450 U/kg, administered as an IV bolus injection, twice weekly, for 6, 4, and 4 weeks, respectively) in five patients with low-grade non-Hodgkin's lymphoma (Ig NHL) and bone marrow involvement and one patient with multiple myeloma (MM). All patients were anemic due to underlying disease. None of the patients had a history of bleeding, hemolysis, renal insufficiency, or other disorders causing anemia in addition to bone marrow infiltrating malignancy. Endogenous EPO serum levels were significantly increased in all patients (7…

A phase-II study of low-dose cyclophosphamide and recombinant human interleukin-2 in metastatic renal cell carcinoma and malignant melanoma.

1989

Recent preclinical and clinical studies that have demonstrated antitumor activity of high-dose recombinant interleukin-2 (rIL-2), and animal models that demonstrated a synergistic effect of low-dose cyclophosphamide, led us to study rIL-2 (Cetus Corp., Emeryville, Calif) in a phase II clinical trial in combination with low-dose cyclophosphamide in 32 patients, 18 with malignant melanoma and 14 with renal cell carcinoma. rIL-2 was given once daily at 3 x 10(6) U/m2, as a 30-min infusion for 14 days in cycle I and for 2 x 5 days in cycles II and III respectively; if tolerated, the dose was increased to a maximum of 6 x 10(6) U m-2 day-1; the cycles, separated by 1 week treatment-free interval…

MACOP-B chemotherapy for the treatment of high grade and intermediate grade non Hodgkin's lymphoma.

1990

Between Nov. 1985 and Nov. 1988, sixty-three patients with high grade malignant (hg) and intermediate grade malignant (img) Non Hodgkin's Lymphoma (NHL) were treated with MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone and bleomycin). Thirty-seven patients received MACOP-B as an upfront treatment modality, whereas twenty-six patients had relapsed disease and received MACOP-B as a salvage protocol. Four weeks after termination of therapy, 75% of patients with de novo NHL and 72% of the patients with relapsed NHL were in complete remission (CR). In the group of newly diagnosed NHL, 22% achieved partial remission (PR) and 3% no change (NC), whereas in the group wi…

Sustained complete hematologic remission after administration of the tyrosine kinase inhibitor imatinib mesylate in a patient with refractory, second…

2002

Abstract Imatinib mesylate, a tyrosine kinase inhibitor targeting bcr-abl, platelet-derived growth factor receptor (PDGF-R), and c-Kit, effectively induces hematologic and cytogenetic remissions in bcr-abl+ chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL) with only mild to moderate side effects. Here, we describe the successful treatment of a 64-year-old man with c-Kit+ secondary acute myeloid leukemia (AML) refractory to standard chemotherapy. Upon 2 weeks of imatinib mesylate administration, the patient achieved a complete hematologic remission in peripheral blood. In addition, complete clearance of leukemic blasts in bone marrow and a significant cytogenetic response…

Molecular analysis of the erythropoietin receptor system in patients with polycythaemia vera

1994

Summary Erythropoietin (EPO) is a potent regulator of the viability, proliferation and differentiation of erythroid progenitor cells. Its effect is mediated by binding to the erythropoietin receptor (EPO-R), a member of a new cytokine receptor family. Alterations of the EPO/EPO-R system have recently been shown to be involved in the pathogenesis of familial erythrocytosis and polycythaemia vera (PV). In order to define whether genetic changes in the EPO-R gene and its ligand play a role in the development of PV, the structure and expression levels of the EPO-R and EPO genes were examined in samples from bone marrow and/or peripheral blood mononuclear cells of 24 patients with PV. As expecte…

Rituximab in vivo purging is safe and effective in combination with CD34-positive selected autologous stem cell transplantation for salvage therapy i…

2002

The purpose of this study was to evaluate feasibility and efficacy of Rituximab included into a sequential salvage protocol for CD20(+) B-NHL in relapse or induction failure. Twenty-seven patients with CD20(+) B-NHL in relapse or induction failure received Rituximab combined with DexaBEAM (R-DexaBEAM) for stem cell mobilization. Additional ex vivo selection of CD34-positive cells was performed using the CliniMacs device. Two doses of Rituximab were included in the high-dose therapy regimen (HDT). R-DexaBEAM was well tolerated and 26 of 27 patients mobilized sufficient numbers of CD34(+) blood stem cells. Application of R-DexaBEAM resulted in significant depletion of peripheral B cells. No t…

Das Chlorom (Granulozytäres Sarkom, Myeloblastom) - Klinik und radiologische Diagnostik -

2000

Six cases of granulocytic sarcoma are presented. A mediastinal chloroma and a tumor of the submandibular gland were observed with two patients as single sign of acute myeloic leukaemia. In one patient a chloroma appeared as first manifestation of acute myeloic leukaemia. Two patients exhibited the tumor as first symptom of a blastic crisis of chronic myelogenous leukaemia (femoral bone, lumbar spine). The sixth patient with a myelodyplastic syndrom showed a chloroma of the breast. Various radiological procedures were applied including plain radiography, MRT, CT and mammography. The results are compared with literature. Principles of therapy were supplemented.

Bone marrow punctures and pain

2004

Abstract We prospectively analysed pain in 263 patients induced by a frequent diagnostic procedure for oncologists, specifically the bone marrow puncture. Substantial pain (5 and more out of 10 on a numerical rating scale) was reported by 30.4% of patients, but physicians did not realize this procedure-related pain of patients in more than 50% of such punctures. The necessity for improved analgesia is emphasized by the fact, that at least 50% of patients experiencing substantial pain wished to receive concomitant medication in future punctures. Duration of the procedure was identified as sole independent predictive factor for patients’ pain intensity, while patients’ characteristics like ge…

Outcome of peripheral blood stem cell mobilization in advanced phases of CML is dependent on the type of chemotherapy applied

1998

High-dose chemotherapy with autologous transplantation of in vivo purged PBSC is a novel investigational approach to treating chronic myelogenous leukemia (CML) patients not responsive to conventional therapy with interferon-alpha (IFN-alpha) and not eligible for allogeneic transplantation. PBSC mobilization using either '5+2/7+3'-type chemotherapy or 'mini-ICE/ ICE' chemotherapy was investigated in 43 patients with advanced phases of Philadelphia (Ph)-positive CML. Thirty patients were in late chronic phase (12 months post diagnosis) and 13 patients in accelerated phase (AP) or blast crisis (BC). Contamination with Ph-positive cells was evaluated in harvests from 37/43 patients. The outcom…

Prevalence and risk factors of bisphosphonate-associated osteonecrosis of the jaw in prostate cancer patients with advanced disease treated with zole…

2008

Abstract Background In addition to other treatments, patients with prostate cancer (pCA) and bone metastasis receive bisphosphonates. Since 2003, a previously unknown side-effect of bisphosphonates—bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ)—has been described, and frequency has since increased. An exact incidence is still unknown. Objectives The aim of this study was to assess the incidence and additional factors in the development of BP-ONJ. Design, setting, and participants From July 2006 to October 2007, patients with advanced pCA and osseous metastasis receiving bisphosphonate therapy in the Department of Urology or Haematology and Oncology at the Johannes-Gutenberg-Un…

Phase I trial of recombinant human tumour necrosis factor alpha in patients with advanced malignancy.

1991

A phase I clinical trial was conducted with recombinant human tumour necrosis factor alpha (rhTNF-alpha) in 62 patients with advanced malignancy refractory to previous standard therapy. rhTNF-alpha was given as a 30 min infusion twice a day at 6 h intervals. A total of 10 different dose levels was escalated in cohorts of 6 patients ranging from 2.5 to 200 micrograms/m2 twice a day for 5 days every second week for a total of 8 weeks followed by a 4-week observation period. Major side-effects of TNF-alpha therapy, seen in almost all patients studied, were fever and chills. As dose-limiting side-effects hypotension and liver toxicity were recorded in 4 of 5 patients treated with 200 micrograms…

Prevalence of bisphosphonate associated osteonecrosis of the jaws in multiple myeloma patients

2010

Abstract Background Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is an adverse effect of bisphosphonate treatment with varying reported incidence rates. Methods In two neighboring German cities, prevalence and additional factors of the development of BP-ONJ in multiple myeloma patients with bisphosphonates therapy were recorded using a retrospective (RS) and cross-sectional study (CSS) design. For the RS, all patients treated from Jan. 2000 - Feb. 2006 were contacted by letter. In the CSS, all patients treated from Oct. 2006 - Mar. 2008 had a physical and dental examination. Additionally, a literature review was conducted to evaluate all articles reporting on BP-ONJ prevalen…
