doxorrubicin

The aims of the present study were to evaluate the protective effects of gallic acid against doxorubicin-induced ovarian toxicity in mice, and to verify the possible involvement of PI3K and mTOR signaling pathway members (PTEN, Akt, FOXO3a and rpS6) in the gallic acid protective actions. Mice were pretreated with NaCl (0.15M, p.o.) (control and doxorubicin groups) or gallic acid (50, 100 or 200mg/kg body weight, p.o.) once daily, for 5 days, and on the third day of treatment, after 1h of treatment administration, the mice received saline solution (i...

Extranodal natural-killer/T-cell lymphoma (ENKTL) is a rare and aggressive Epstein-Barr virus related mature T-cell and natural-killer malignancy. Although highly prevalent in South America, few studies covering data from this geographic location have been published. Therefore, this study aims to report clinical characteristics, prognostic factors, and outcomes in a multicenter cohort of ENKTL patients from Brazil. This retrospective, observational and multicenter study included 98 ENKTL patients treated during two decades in Brazil...

Background : Myocardial toxicity is a common side effect of doxorubicin (DOXO) therapy in breast cancer patients. We hypothesized that DOXO-induced cardiotoxicity may be related to the release of inflammatory cytokines in response to the treatment. This study aimed to assess changes in plasma levels of interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor (TNF) after chemotherapy and to correlate these levels with cardiac biomarkers and clinical data. Methods : Sixty-four patients with breast cancer treated with DOXO were included...

BACKGROUND: Chemotherapy with doxorubicin and cyclophosphamide, although efficient for treating breast cancer, is associated with cardiovascular complications. Recent studies seek to identify methods that can early detect cardiological and vascular changes as a strategy to decrease the incidence of cardiovascular comorbidities. OBJECTIVE: To evaluate the role of arterial stiffness measurement in the monitoring of doxorubicin and cyclophosphamide-induced cardiotoxicity in breast cancer patients...

INTRODUCTION: Hepatic transarterial chemoembolization is a widely used technique for the treatment of hepatocellular carcinoma.

Nowadays, the advances in knowledge about oncologic treatment have led to an increase in survival rate for cancer patients and, consequently, a growing concern about the adverse effects of treatment in medium and long term, in order to ensure the future quality of life. For male patients in reproductive age or younger, one of the key concerns after cancer therapy is their ability to father children, since anticancer drugs exert cytotoxic effects on germ cells. Considering the incidence of cancer in children and adolescents and the vulnerability of these developmental phases to chemical injuries, this review is an attempt to highlight the importance of juvenile experimental models to test new anticancer drugs and agents with protective action...

BACKGROUND: The overall survival and relapse-free survival have increased with current chemotherapy in patients with non-lymphoma Hodgkin. A useful tool to evaluate projections is the International Prognostic Index. Our aim was to evaluate the relation between the prognosis established with the International Prognostic Index and the survival obtained in two years by patients with diffuse large B-cell lymphoma. METHODS: An observational, longitudinal, prospective study was carried out...

PURPOSE: Embryonal sarcoma accounts for 6 % of liver tumors. This study reviews its features and the results of treatment in a referral center. METHODS: We retrospectively reviewed liver tumors treated between 1995 and 2011. PRETEXT staging and biopsy were used to tailor chemotherapy according to SIOP protocols. Radical surgery was performed when possible. Complications and cumulative survival were the outcome endpoints. RESULTS: Six out of 156 primary liver tumors (four males and two females) were sarcomas...

Noni, a Hawaiian name for the fruit of Morinda citrifolia L., is a traditional medicinal plant from Polynesia widely used for the treatment of many diseases including arthritis, diabetes, asthma, hypertension and cancer. Here, a commercial noni juice (TNJ) was evaluated for its protective activities against the lesions induced by mitomycin C (MMC) and doxorrubicin (DXR) using the Somatic Mutation and Recombination Test (SMART) in Drosophila melanogaster. Three-day-old larvae, trans-heterozygous for two genetic markers (mwh and flr3 ), were co-treated with TNJ plus MMC or DXR...

The toxicity profile of trabectedin in the OVA-301 trial, that combined trabectedin with pegylated liposomal doxorubicin for the treatment of patients with ovarian cancer, has shown to be predictable and manageable. No unexpected toxicities were found, with neutropenia and transient increase in transaminases as the most common adverse events reported. The elevation in transaminases appeared early and generally decreased in incidence and intensity over subsequent cycles, with no major clinical consequences. A similar safety profile was seen in the analysis of the older patients in the trial...

BACKGROUND: Breast carcinoma during pregnancy put the health of the mother in conflict with that of the foetus. The aim is to give optimal treatment to the mother to maximise the chances of survival, whilst minimising the risk of harm of the foetus. We report the epidemiology, pathology, clinical picture, therapeutic management and foetal outcome of pregnant women with breast cancer treated in our institution. PATIENTS AND METHODS: Twenty-two pregnant breast cancer patients were treated in our hospital from January 1996 to October 2006...

UNLABELLED: Amifostine has emerged as a pancytoprotectant shown protection against nephrotoxicity, neurotoxicity and ototoxicity in preclinical studies. METHODS: We designed a prospective comparative randomized trial to evaluate the cytoprotective effects of amifostine in patients with osteosarcoma receiving cisplatin and doxorrubicin. Patients were evaluated for renal, hearing and cardiac toxicity. RESULTS: We included 28 patients, mean age was 11...

INTRODUCTION: Morbidity of tissue extravasations is far of being properly considered in our hospitals. The increased survival rate in very low prematures and severe oncological patients has also produced an increase in the incidence of this complication, that in the most of the cases are not agressively treated in order to minimize the extravasation consequences. We have reviewed our experience in the treatment of these lessions using either injection and saline flushing of the subcutaneous (Gault tissue protocol, 1993) or coverage with artificial dermis in cases with irreversible necrosis...

PURPOSE: In this study we evaluated the activity and toxicity of a combination of 5-fluorouracil continuous infusion and vinorelbine as second or third line chemotherapy in metastatic breast cancer (MBC). PATIENTS AN METHODS: A total 24 patients who had received doxorrubicin and/or paclitaxel were included in this study. The regimen consisted in 5-fluorouracil 1 gr/m(2) BSA continuous infusion for 3 days and vinorelbine 30 mg/m(2) intravenous (IV) on day 1. The cycles were repeated every 21 days for 6 cycles...

Human epidermal growth factor receptor (HER 2) is amplified in 25 to 30% of breast cancer patients and those whose tumors demonstrate HER 2 gene amplification and protein overexpression have an inferior prognosis manifested by shorter disease-free and overall survival. Trastuzumab, the humanized murine anti-HER 2 monoclonal antibody, inhibits tumor growth when used alone and has synergistic and additive effects when used with chemotherapeutic agents (paclitacel-doxorrubicine). At the present time, the accurate diagnostic assessment of HER 2 is essential for appropriate application of the humanized anti HER 2 monoclonal antibody, trastuzumab, for the treatment of patients with metastatic breast cancer...

Clinical manifestation of carcinoide syndrome are often difficult to control with medical treatment and so present a large problem for doctors. In the majority of cases, such manifestations are seen in patients with hepatic metastases. In such cases the control of the problem can be achieved by local hepatic treatment. A 57 year old patient with carcinoide syndrome for a year, with extensive hepatic tumor from a carcinoide tumor, whose origins were not lokted, had a urinary excretion 5-hidroxi-indolacetic = 73 mg in 24 hours, he used cyproheptadin, loperamida and metisergida without showing improvement...

Up to now, the best treatment for patients with acute myelogenous leukemia (AML) is the induction of bone marrow hypoplasia by ablative combined chemotherapy; the prototype of these schedules is the so-called 7 + 3 (seven days of continuous infusion of cytarabine and three days of one-hour infusion of any anthracycline); these schedules require the support of both platelet transfusions and antibiotics. Other non-ablative schedules have also been tried in the treatment of such patients. Here we analyze the results of the treatment of 76 adult patients with AML; 43 were treated with the classical 7 + 3 schedule, whereas 33 were treated with a combination of chemotherapy used in non-ablative doses (TADOP: thioguanine, arabinosyl-citosine, doxorrubicin, vincristine and prednisone)...
