Anti-endothelin drugs in solid tumors
2010
Importance of the field: The endothelin (ET) axis, which includes the biological functions of ETs and their receptors, has played a physiological role in normal tissue, acting as a modulator of vasomotor tone, tissue differentiation and development, cell proliferation and hormone production. Interestingly, it also functions in the growth and progression of various tumors. Several researchers have identified the blockade of the ET-1 receptor as a promising therapeutic approach. Areas covered in this review: The clinical investigation of an orally bioavailable ET antagonist, atrasentan, in prostate cancer, is encouraging. In this neoplasia, it has shown antitumor activity, bone metastasis con…
Is G8 geriatric assessment tool useful in managing elderly patients with metastatic pancreatic carcinoma?
2020
Abstract Aim This paper aims to analyze the usefulness of the G8 geriatric oncology questionnaire in patients with advanced/metastatic pancreatic adenocarcinoma (aPAC) and its possible association with different clinical outcomes. Methods Patients age > 70 years were screened with the G8 tool and treated with intravenous nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 for 3 consecutive weeks followed by one-week rest as prescribed after clinical evaluation by treating oncologists. Patient’s charts were evaluated for type and severity of toxicity, 2 cycle rate of completion, discontinuation rate, delays, dose reductions, and other outcomes response rates, progression-free, and overall su…
IFN-alpha Stimulates Proliferation and Cytokine Secretion of CD40-Stimulated B Cell Chronic Lymphocytic Leukemia Cells In Vitro
1999
Interferon (IFN)-alpha has a therapeutic effect in several B cell malignancies, including low-grade non-Hodgkin's lymphoma (NHL), multiple myeloma, and hairy cell leukemia, whereas its efficacy in the treatment of B cell chronic lymphocytic leukemia (B-CLL) is rather limited. In the present study, we investigated the effect of IFN-alpha on the biologic functions of B-CLL cells, which were stimulated by cross-linking of the CD40 antigen. In cell samples from 16 B-CLL patients, the addition of IFN-alpha to CD40-stimulated purified B-CLL cells caused a significant increase in [3H]thymidine uptake (p < 0.003). In B-CLL cells maximally activated by CD40 cross-linking and interleukin-2 (IL-2)/IL-…
Supportive care of the older cancer patient
2003
Aging is associated with decreased functional reserve of multiple organ systems and with changes in the pharmacokinetics and pharmacodinamics of drugs. Older individuals express enhanced susceptibility to the complications of cytotoxic chemotherapy, especially to myleotoxicity, mucositis, cardiotoxicity and neurotoxicity. The management of older individuals with chemotherapy involves then prevention of these complications. General precautions include proper patient selection, based on the comprehensive geriatric assessment (CGA), dose adjustment for agents that are renally excreted to the patient creatinine clearance and maintenance of hemoglobin levelsor =12 g/dl. Filgrastim and pegfilgras…
Systemic chemotherapy in elderly patients with locally advanced and/or inoperable squamous cell carcinoma of the head and neck: impact of anemia and …
2003
Abstract A review of the incidence and management of anemia in elderly patients with head and neck carcinoma treated with systemic chemotherapy. The role of recombinant human erythropoietin in preventing or correcting chemotherapy-related anemia has been focused. Data concerning the prospective use of recombinant human erythropoietin (rhEpo) in a series of unfit elderly patients (EPs) treated with carboplatin plus 5-fluorouracil. Patients were randomly assigned to receive subcutaneous rhEpo 10,000 U three times per week (TIW) (23 elderly patients) or no treatment (22 control patients). Recombinant hEpo was able to prevent anemia and to reduce transfusional requirements in treated patients a…
Analysis of molecular mechanisms and anti-tumoural effects of zoledronic acid in breast cancer cells
2012
Zoledronic acid (ZOL) is the most potent nitrogen-containing bisphosphonate (N-BPs) that strongly binds to bone mineral and acts as a powerful inhibitor of bone resorption, already clinically available for the treatment of patients with osteolytic metastases. Recent data also suggest that ZOL, used in breast cancer, may provide more than just supportive care modifying the course of the disease, though the possible molecular mechanism of action is still unclear. As breast cancer is one of the primary tumours with high propensity to metastasize to the bone, we investigated, for the first time, differential gene expression profile on Michigan Cancer Foundation-7 (MCF-7) breast cancer cells tre…
Infectious complications in patients with myelodysplastic syndromes: A review of the literature with emphasis on patients treated with 5-azacitidine.
2017
Myelodysplastic Syndromes are oligo-clonal stem cell disorders that are associated with cytopenias in the peripheral blood. Major causes for morbidity and mortality in myelodysplastic syndromes (MDS) patients are infections mostly due to bacteria or fungi. Beside leucopenia per se in affected patients, function of white blood cells particularly that of neutrophils seems to be impaired. Here we summarize the available data on infections in MDS patients in general and particularly those treated with 5-azacitidine.
Steroid Receptor Expression in Endometria from Women Treated with Tamoxifen
1998
Abstract Breast cancer patients receiving tamoxifen (Tam) are at an increased risk for developing endometrial carcinomas, possibly due to the partial estrogenic effect of Tam on endometrial cells. Progestational therapy has not routinely been included in Tam regimens. It was our aim to determine the presence of estrogen receptors (ERs) and progesterone receptors (PRs) in normal and abnormal endometria from postmenopausal women with breast cancer who were treated with Tam. Standard immunohistochemical staining of ERs and PRs was performed on paraffin sections from formalin-fixed uterine curettings or hysterectomy specimens from 40 patients who had received 20–40 mg of Tam daily for a minimum…
The Patient's Anastrozole Compliance to Therapy (PACT) Program: a randomized, in-practice study on the impact of a standardized information program o…
2013
BACKGROUND Compliance and persistence are often overlooked in adjuvant breast cancer treatment. PATIENTS AND METHODS PACT was a prospective, multicenter, randomized, open, parallel-group study assessing whether educational materials (EMs) enhanced compliance with aromatase inhibitor (AI) therapy in postmenopausal women with early, hormone-receptor-positive (HR+) breast cancer. The primary end points were compliance (proportion taking ≥ 80% anastrozole) at 12 months and persistence (proportion reporting anastrozole intake during the study period). RESULTS Four thousand eight hundred and forty-four patients were randomly assigned 1:1 to receive standard therapy or standard therapy with EMs. T…
Differential miRNA expression defines migration and reduced apoptosis in follicular thyroid carcinomas.
2013
The objective of the study was to identify microRNAs (miRs) characteristic for follicular thyroid carcinoma (FTC) and to define their role in tumorigenesis. A miR-microarray study was conducted to identify miRs differentially expressed between FTCs and their surrounding tissues. Selection was further reinforced by a literature review. Four miRs were selected and confirmed by RT-qPCR: miR-146b, -183, -221 were up-regulated, whereas miR-199b down-regulated in FTCs. The influence of these miRs on cell proliferation, cell cycle, apoptosis and migration was studied in HTori and FTC-133 cells. Functional characterization suggests an impact of miR-183 and miR-146b in FTC development. Overexpressio…
