  • Intravenous Ascorbate and Oncologic Agents
    © PAUL S. ANDERSON 2013 INTRAVENOUS ASCORBATE AND ONCOLOGIC AGENTS Updated Data Review and Policies for concurrent use at Anderson Medical Specialty Associates, Southwest College of Naturopathic Medicine Research Institute and Medical Center and Bastyr University Clinical Research Center Paul S. Anderson 05/01/2013 © Paul S. Anderson – All rights reserved – Reproduction and redistribution only allowed with proper attribution. Abstract: Intravenous application of ascorbic acid (IVAA) has a long history in adjunctive oncology communities. Its use has stimulated much debate regarding efficacy, safety and appropriate inclusion in oncologic practice. The potential for both antagonistic and synergistic interactions between IVAA and chemotherapies or radiation has existed for some time as an unanswered or confusing question in the naturopathic and allopathic oncology community. The purpose of this publication is to summarize and update the state of understanding of this complicated topic for clinicians employing either standard or integrative oncology care. INTRAVENOUS ASCORBATE AND ONCOLOGIC AGENTS Introduction: Intravenous ascorbate has been used in oncology practice by naturopathic and alternative allopathic physicians for decades. Published data regarding this therapy shows that it continues to be one of the most commonly employed alternative IV therapies. This popularity has both stimulated awareness of this therapy and concern regarding not only the safety and efficacy of IVAA in the oncology patient but also for the potential of antagonistic

  • Safe Handling of Cytotoxic, Monoclonal Antibody & Hazardous Non-Cytotoxic Drugs
    PROCEDURE SAFE HANDLING OF CYTOTOXIC, MONOCLONAL ANTIBODY & HAZARDOUS NON-CYTOTOXIC DRUGS TARGET AUDIENCE All nursing, pharmacy and medical staff involved with dispensing, preparation, or administration of medicines. STATE ANY RELATED PETER MAC POLICIES, PROCEDURES OR GUIDELINES Administration and Management of Anti-Cancer Drugs Administration of Cytotoxics in the Home/Community Collection and Disposal of Soiled Linen Dangerous Goods and Hazardous Substances Environmental Management Individual Personal Protective Equipment (Cancer Research Division) Management of Cytotoxic Drug Spill Medication Management Medication Management for Nurses Pharmaceutical Review & Medication Supply Personal Protective Equipment Administration of Intravesical Immunotherapy BCG PURPOSE This procedure provides direction to all hospital staff involved in the management, preparation, transportation, administration of hazardous drugs and related wastes. In particular, safe handling practices for cytotoxic and hazardous non-cytotoxic drugs are outlined. BACKGROUND Hazardous drugs are regulated medicines that have been classified by the National Institute for Occupational Safety and Health (NIOSH) of the United States and/or the Cancer Institute New South Wales as posing a risk to health from occupational exposure. Exposure to hazardous drugs can result in adverse health effects in healthcare workers. The health risk depends on how much exposure a worker has to these drugs and the specific toxicity of the drug. The occupational exposure risk of hazardous drugs is therefore evaluated according to risk of internalisation (by ingestion, absorption through mucous membranes, and penetration of skin) and risk of toxicity (carcinogenicity, genotoxicity, teratogenicity, and reproductive or fertility impairment, organ toxicity) at low doses and continuous exposure. Hazardous drugs include both cytotoxic and non-cytotoxic medicines such as chemotherapy, monoclonal antibodies, immunomodulatory drugs, and some anti-infective drugs.

  • Fludarabine-Treosulfan Compared To
    Saraceni et al. Journal of Hematology & Oncology (2019) 12:44 https://doi.org/10.1186/s13045-019-0727-4 RESEARCH Open Access Fludarabine-treosulfan compared to thiotepa-busulfan-fludarabine or FLAMSA as conditioning regimen for patients with primary refractory or relapsed acute myeloid leukemia: a study from the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation (EBMT) Francesco Saraceni1,16* , Myriam Labopin2, Arne Brecht3, Nicolaus Kröger4, Matthias Eder5, Johanna Tischer6, Hélène Labussière-Wallet7, Hermann Einsele8, Dietrich Beelen9, Donald Bunjes10, Dietger Niederwieser11, Tilmann Bochtler12, Bipin N. Savani13, Mohamad Mohty14 and Arnon Nagler2,15 Abstract Background: Limited data is available to guide the choice of the conditioning regimen for patients with acute myeloid leukemia (AML) undergoing transplant with persistent disease. Methods: We retrospectively compared outcome of fludarabine-treosulfan (FT), thiotepa-busulfan-fludarabine (TBF), and sequential fludarabine, intermediate dose Ara-C, amsacrine, total body irradiation/busulfan, cyclophosphamide (FLAMSA) conditioning in patients with refractory or relapsed AML. Results: Complete remission rates at day 100 were 92%, 80%, and 88% for FT, TBF, and FLAMSA, respectively (p = 0.13). Non-relapse mortality, incidence of relapse, acute (a) and chronic (c) graft-versus-host disease (GVHD) rates did not differ between the three groups. Overall survival at 2 years was 37% for FT, 24% for TBF, and 34% for FLAMSA (p = 0.10). Independent prognostic factors for survival were Karnofsky performance score and patient CMV serology (p =0.01; p = 0.02), while survival was not affected by age at transplant. The use of anti-thymocyte globulin (ATG) was associated with reduced risk of grade III–IV aGVHD (p = 0.02) and cGVHD (p = 0.006), with no influence on relapse.

Patients in relapse after first-, second-, or third-line therapy received 40 mg m intravenous (i.v.) À2 À2 Clinical Studies cisplatin, 1000 mg m i.v. gemcitabine, and 2500 mg m i.v. treosulfan on days 1 and 8. Cisplatin, gemcitabine, and treosulfan therapy was repeated every 5 weeks until progression of disease occurred. A maximum of 11 CGT cycles (mean, two cycles) was administered per patient. Four patients (4%) showed a partial response; 15 (17%) patients had stable disease; and 72 (79%) patients progressed upon first re-evaluation. Overall survival of all 91 patients was 6 months (2-year survival rate, 7%). Patients with partial remission or stable disease exhibited a median overall survival of 11 months (2-year survival rate, 36%), while patients with disease progression upon first re-evaluation had a median overall survival of 5 months (2-year survival rate, 0%). Treatment with CGT was efficient in one-fifth of the pretreated relapsed stage IV melanoma patients achieving disease stabilisation or partial remission with prolonged but limited survival.
