A phase I-II study of cyclophosphamide, epidoxorubicin, levofolinic acid/5-fluorouracil and recombinant human granulocyte colony stimulating factor i…
1994
Thirty patients with measurable metastatic breast carcinoma were treated with a combination of cyclophosphamide 600 mg/m2 on day 1, levofolinic acid 100 mg/m2 plus 5-fluorouracil 375 mg/m2 on days 1-3, and epidoxorubicin (EDXR) in three refracted doses on days 1-3 with G-CSF rescue for 10 days. In the phase I part of the study, groups of 3 patients received EDXR 20, 25, 30, 35, and 40 mg/m2/day until the dose limiting toxicity (DLT) was reached. At the dose of 40mg/m2/day prolonged grade 4 leukopenia, severe proctitis, and grade 3 diarrhea represented the DLT. All subsequent partients were treated at the maximal tolerated dose of EDXR (35 mg/m2/day). In the group of 18 patients treated at 3…
Cardiovascular imaging in the diagnosis and monitoring of cardiotoxicity: cardiovascular magnetic resonance and nuclear cardiology
2016
Chemotherapy-induced cardiotoxicity (CTX) is a determining factor for the quality of life and mortality of patients administered potentially cardiotoxic drugs and in long-term cancer survivors. Therefore, prevention and early detection of CTX are highly desirable, as is the exploration of alternative therapeutic strategies and/or the proposal of potentially cardioprotective treatments. In recent years, cardiovascular imaging has acquired a pivotal role in this setting. Although echocardiography remains the diagnostic method most used to monitor cancer patients, the need for more reliable, reproducible and accurate detection of early chemotherapy-induced CTX has encouraged the introduction o…
The use of same in chemotherapy-induced liver injury
2018
Drug-induced liver injury (DILI) remains the most common cause of acute liver failure in the Western world. Chemotherapy is one of the major class of drugs most frequently associated with idiosyncratic DILI. For this reason, patients who receive chemotherapy require careful assessment of liver function prior to treatment to determine which drugs may not be appropriate and which drug doses should be modified. S-adenosylmethionine (SAMe) is an endogenous agent derived from methionine. Its supplementation is effective in the treatment of liver disease, in particular intrahepatic cholestasis (IHC). The target of this review is to analyze the mechanisms of hepatotoxicity of the principal antican…
Diagnosis, monitoring and management of immune-related adverse drug reactions of anti-PD-1 antibody therapy.
2015
PD-1 checkpoint inhibitors are associated with a specific spectrum of immune-related adverse events. This spectrum is different from toxicities known for kinase inhibitors or cytotoxic drugs. Since PD-1 directed therapies show effectivity in an increasing number of malignant diseases, their clinical usage will increase rapidly. Therefore clinicians from different specialities such as medical oncology, internal medicine, family doctors and emergency unit staff should be aware of the adverse effects of PD-1 checkpoint inhibitors to avoid delays in diagnosis and treatment. Based on pooled data from pivotal trials as reported by the European Medicines Agency, the present paper reviews incidence…
Nationwide Analysis on Surgical Staging Procedures and Systemic Treatment for Patients With Endometrial Cancer in Germany
2012
ObjectiveIn 2009 and 2006, the Arbeitsgemeinschaft Gynäkologische Onkologie evaluated therapeutic approaches for endometrial carcinoma (EC) in Germany.Methods and MaterialsA questionnaire was developed and sent to 775 German gynecologic departments in 2009 (500 in 2006). The results of the questionnaires were compared with each other and with the recommendations of the Arbeitsgemeinschaft Gynäkologische Onkologie’s guideline. Subgroup analyses were performed, dividing the participating centers into small and large centers and into centers with less and more experience with EC.ResultsResponses were available in 33.3% in 2009 and 35.8% in 2006. Comparing 2009 with 2006, it became apparent tha…
The role of insulin-like growth factor II in the malignant transformation of rat liver oval cells
1997
Oval cells are small nonparenchymal epithelial cells that first appear in the periportal areas of the liver and thereafter invade the whole parenchyma when mice or rats are exposed to a variety of chemical carcinogens. In the present study we have analyzed the expression of insulin-like growth factor II (IGF II) in the recently established oval cell line OC/CDE 22 and its malignantly transformed counterpart (the M22 cells) and the biological consequences of the constitutive expression of IGF II in oval cells. OC/CDE 22 cells do not express the above-mentioned growth factor, whereas the M22 cells do and addition of a neutralizing anti-IGF II antibody to M22 cells resulted in an almost comple…
Subclinical Cardiotoxicity: The Emerging Role of Myocardial Work and Other Imaging Techniques.
2021
In recent years, the cancer survival of patients has improved thanks to advances in the pharmacological field. In many guidelines, cardiotoxicity induced by anticancer drugs was defined as a reduction from baseline in the left ventricular ejection fraction (LVEF) assessed by echocardiography. It is known that LVEF is not a sensible parameter in the detection of cardiotoxicity. Therefore, a decrease from baseline in the global longitudinal strain (GLS) or troponins elevation is used to detect subclinical cardiotoxicity. LVEF and GLS as well as the increase in some biomarkers are influenced by loading conditions that are frequent during chemotherapy. Other parameters not influenced by loading…
Oral vinorelbine in the treatment of non-small cell lung cancer: rationale and implications for patient management.
2007
Vinorelbine is an established treatment for advanced non-small cell lung cancer (NSCLC), both as a single agent and in combination chemotherapy. Recently, an oral form of this agent has been developed. Before accepting an established agent in a different administration form, rigorous testing is required to answer such questions as reliable bioavailability, continued safety and preservation of efficacy. In addition, an oral agent must provide patient convenience and acceptance, while being an economically sound approach. Oral vinorelbine was found to have acceptable and reliable pharmacokinetic profiles at clinically relevant dosage levels. Oral vinorelbine was found to have approximately 40…
A case of guillain-barre syndrome in a patient with non small cell lung cancer treated with chemotherapy
2006
Guillain-Barré Syndrome (GBS) is a demyelinating polyneuropathy of probable autoimmune pathogenesis characterized by rapidly progressive symmetric paralysis. In the literature some cases of GBS associated with anticancer chemotherapy are reported. We present a case of a 55-year old woman who complained of progressive motor deficit in four limbs, areflexia in lower limbs and facial nerve paralysis one week after beginning cisplatin-gemcitabine chemotherapy for metastatic lung cancer. The cerebrospinal fluid analysis showed a strong positive Pandy reaction with 435 mg/dl total protein. The electromyography and the electroneuronography established the diagnosis of inflammatory demyelinating po…
