Background: Erythropoietin (EPO) is a hypoxia-inducible stimulator of erythropoiesis. Besides its traditional application in anemia therapy, it offers an effective treatment in the cancer patients, especially those who receive chemotherapy. Several reports indicated that it could promote the tumor cell proliferation through its specific receptor (EPOR). Unfortunately, the role of EPO/EPOR in hepatocellular carcinoma (HCC) progressing is still uncertain. Methods: Protein in tumor tissue from HCC patients or H22 tumor-bearing mice was detected with immunohistochemistry...

Multiple myeloma (MM) is an incurable disease of malignant plasma B-cells that infiltrate the bone marrow (BM), resulting in bone destruction, anemia, renal impairment and infections. Physiologically, the BM microenvironment is hypoxic and this promotes MM progression and contributes to resistance to chemotherapy. Since aberrant hypoxic responses may result in the selection of more aggressive tumor phenotypes, we hypothesized that targeting the hypoxia-inducible factor (HIF) pathways will be an effective anti-MM therapeutic strategy...

OBJECTIVE: Women with an inherited BRCA1 or BRCA2 mutation may have an impaired ability to repair chemotherapy-induced damage as a result of a state of haploinsufficiency and may experience greater treatment-related toxicity. The objective of this study was to compare the hematologic adverse effect profiles associated with platinum-based chemotherapy in ovarian cancer patients with and without germline BRCA mutations. METHODS: We conducted a retrospective analysis of patients treated for high-grade serous ovarian cancer at Princess Margaret Cancer Center, Toronto, Ontario between January 2000 and December 2015...

Arginine vasopressin (AVP) made by hypothalamic neurons is released into the circulation to stimulate water resorption by the kidneys and restore water balance after blood loss. Patients who lack this antidiuretic hormone suffer from central diabetes insipidus. We observed that many of these patients were anemic and asked whether AVP might play a role in red blood cell (RBC) production. We found that all three AVP receptors are expressed in human and mouse hematopoietic stem and progenitor cells. The AVPR1B appears to play the most important role in regulating erythropoiesis in both human and mouse cells...

Erythropoietin (EPO) is the main hormone driving mammalian erythropoiesis, with activity mediated via the surface receptor, EPO-R, on erythroid progenitor cells. Recombinant human EPO is currently used clinically for the treatment of anemia in patients with end-stage renal disease, and in certain cancer patients suffering from anemia induced either by the tumor itself or by chemotherapy. EPO-R expression is also detected in non-erythroid cells, including macrophages present in the peritoneum, spleen, and bone marrow (BM)...

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome characterized by overwhelming immune activation. A steroid and chemotherapy-based regimen remains as the first-line of therapy but it has substantial morbidity. Thus, novel, less toxic therapy for HLH is urgently needed. Although differences exist between familial HLH (FHL) and secondary HLH (sHLH), they have many common features. Using bioinformatic analysis with FHL and systemic juvenile idiopathic arthritis, which is associated with sHLH, we identified a common hypoxia-inducible factor 1A (HIF1A) signature...

Peptide Receptor Radionuclide Therapy (PRRT) may induce long-term toxicity to the bone marrow (BM). The aim of this study was to analyze persistent dysfunction of the hematopoietic system after PRRT with (177)Lu-DOTATATE in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Methods: The incidence and course of persistent hematological dysfunction (PHD) was analyzed in 274 (=GEP-NET) out of 367 patients with somatostatin receptor-positive tumors. PHD was defined as diagnosis of Myelodysplastic Syndrome (MDS), Acute Myeloid Leukemia (AML), Myeloproliferative Neoplasms (MPN), Myelodysplastic/Myeloproliferative neoplasms (MDS/MPN) or otherwise unexplained cytopenia (for more than 6 months)...

BACKGROUND: For the treatment of patients with cancer to be successful and well-tolerated, the complications and side effects of the disease and its treatment must be treated and limited as far as possible. Summarized recommendations based on the constantly increasing evidence in the area of supportive care must be defined, standardized, and communicated. METHODS: We systematically reviewed the literature on the topics of anemia, neutropenia, nausea/vomiting, diarrhea, oral mucositis, skin toxicity, and peripheral neurotoxicity induced by cancer treatment, as well as osseous complications, extravasation, and side effects of radiotherapy...

PURPOSE: Low-dose fractionated radiation therapy (LDFRT) induces effective cell killing through hyperradiation sensitivity and potentiates effects of chemotherapy. We report our second investigation of LDFRT as a potentiator of the chemotherapeutic effect of induction carboplatin and paclitaxel in locally advanced squamous cell cancer of the head and neck (SCCHN). EXPERIMENTAL DESIGN: Two cycles of induction therapy were given every 21 days: paclitaxel (75 mg/m(2)) on days 1, 8, and 15; carboplatin (area under the curve 6) day 1; and LDFRT 50 cGy fractions (2 each on days 1, 2, 8, and 15)...

Kaposi's sarcoma is associated with immunosuppressant treatment administered to patients with organ transplant and other immune related disorders. Several case reports have reported association of Kaposi's sarcoma and steroids. Almost all patients in those case reports had localised disease to skin and they responded to tapering doses or discontinuation of steroids. Here we present a case of an elderly asthmatic man who was using self-medication with systemic and inhaled steroids for about two decades. He presented with widespread skin lesions and anemia...

Chemotoxicity due to unwanted p53 activation in the bone marrow remains an unmet clinical challenge. Doxorubicin, a first-line chemotherapy drug, often causes myelosuppression in patients, thus limiting its effectiveness. In this study, we discovered that C646, a reversible p300 inhibitor, downregulates p53 transcription and selectively protects noncancerous cells from p53-dependent apoptosis. C646 treatment blocked acetylation of specific lysine residues that regulate p53 activity. Exploitation of differential p53 genetic backgrounds between human hematopoietic and colorectal cancer cells improved the therapeutic index of doxorubicin with C646 cotreatment...

Erythropoietin (EPO) is an erythropoiesis stimulating growth factor and hormone. EPO has been widely used in the treatment of chronic renal failure, cancer, and chemotherapy-related anemia for three decades. However, many clinical trials showed that EPO treatment may be associated with tumorigenesis and cancer progression. EPO is able to cross blood-brain barriers, and this may lead to an increased possibility of central nervous system tumors such as glioblastoma. Indeed, EPO promotes glioblastoma growth and invasion in animal studies...

In analogy to apoptosis of nucleated cells, erythrocytes may enter eryptosis characterized by cell shrinkage and cell membrane scrambling. Eryptotic erythrocytes are rapidly cleared from circulating blood and may adhere to the vascular wall. Stimulation of eryptosis thus impairs microcirculation and leads to anemia as soon as the loss of erythrocytes cannot be fully compensated by enhanced erythropoiesis. Signaling stimulating eryptosis includes increase of cytosolic Ca2+ -activity, ceramide, caspases, calpain, p38-kinase, protein-kinase C, Janus-activated kinase 3, casein-kinase 1α, and cyclin-dependent kinase 4...

β-thalassemia major is a hereditary anemia resulting from defects in β-globin production. It is also characterized by a hypercoagulable state with an increased risk of thrombosis. Thalidomide, a drug known for its immunomodulating and antiangiogenic properties, has recently been demonstrated to induce γ-globin gene expression and to increase the proliferation of erythroid cells. An increasing incidence of thromboembolic events in thalidomide-treated patients has been reported. This is often in the context of thalidomide combinations with other drugs, including steroids and particularly anthracycline-based chemotherapy, and with very low incidence of thrombosis with single-agent thalidomide treatment...

PURPOSE: The US Food and Drug Administration (FDA) has approved epoetin and darbepoetin for chemotherapy-induced anemia (CIA). Approved epoetin and darbepoetin dosing schedules were three times per week and weekly, respectively, although off-label, less frequent scheduling was common. In 2004, 2007, and 2008, a US Food and Drug Administration Advisory Committees warned of risks associated with erythropoiesis-stimulating agents. During this period, lawsuits alleging illegal darbepoetin marketing practices have concluded, resulting in $1...
