UNLABELLED Cytotoxic chemotherapy, hormonal therapy and molecular targeted therapy are the three major classes of drugs used to treat breast cancer. Imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), (18)F-FDG positron emission tomography (PET)/CT and bone scintigraphy each have a distinct role in monitoring response and detecting drug toxicities associated w...
Classical cytotoxic treatment of rhabdomyosarcoma (RMS) is often accompanied by significant morbidity and poor response. This cytotoxic therapy may induce a multidrug resistance (MDR) phenotype in RMS which is associated with decreased effectiveness of chemotherapy. The majority of MDR molecules belong to a family of ABC (ATP binding cassette) transporters. Studies of drug resistance in RMS sug...
Expression of the BCR-ABL chimeric gene in chronic myeloid leukemia results in the inhibition of apoptosis, a genetically programmed process of autonomous cell death. BCR-ABL and other genetic factors that suppress apoptosis confer cross-resistance to cytotoxic agents with diverse mechanisms of action. Eradication of the chronic myeloid leukemia clone requires strategies that circumvent this in...
Adoptive immunotherapy with murine tumor-specific T lymphocytes engineered to secrete interleukin 2.
Adoptive immunogene therapy of cancer is not widely studied, although it has been proposed as a promising strategy for cancer gene therapy. One of the major obstacles to this approach is the difficulty in introducing cytokine genes efficiently into T lymphocytes. In this report, we developed an adoptive immunotherapy model with murine tumor-specific cytotoxic T lymphocytes. By using an adenovir...
Breast cancer is sensitive to several cytotoxic drugs. Combination cytotoxic regimens are associated with higher response rates and longer durations of response and, occasionally, survival, than are single-agent regimens. However, combination regimens of conventional agents have not changed the course of the disease. In the past decade, numerous newer cytotoxic agents have been developed. Gemci...
BACKGROUND Glioblastoma (GBM) is the most common malignant brain tumor in adults and is associated with a poor prognosis. Cytotoxic T lymphocyte antigen -4 (CTLA-4) blocking antibodies have demonstrated an ability to generate robust antitumor immune responses against a variety of solid tumors. 4-1BB (CD137) is expressed by activated T lymphocytes and served as a co-stimulatory signal, which pro...
The effect of cytotoxic therapy on the proliferation of squamous cell carcinoma of the head and neck in vivo in patients was evaluated before and 15-35 days after the start of therapy. To accomplish this, iododeoxyuridine was administered at t = 0, and bromodeoxyuridine was administered 15-35 days later during treatment with a tumor biopsy obtained for study immediately after each pyrimidine in...
