taxus brevifolia/化学疗法

The drug taxol has been hailed by many in the cancer community as a major breakthrough in the treatment of cancer. It has already been approved in use against ovarian and advanced breast cancer in many countries worldwide. Taxol has also promoted profound debates in the policy arena not, as one

Dealing with cancer is of importance due to enhanced incidence rate of this life-threatening disorder. Chemotherapy is an ideal candidate in overcoming and eradication of cancer. To date, various chemotherapeutic agents have been applied in cancer therapy and paclitaxel (PTX) is one of them. PTX is

Ovarian cancer is most frequently diagnosed at an advanced stage. In recent years there has been intense interest in the chemotherapy of this disease. About cisplatin, the most active agent in the treatment of advanced ovarian cancer, some questions are only partially answered, as the optimal dose,

Breast cancer is the most common malignancy in women, accounting for about 18% of female cancers, and over half a million new cases are diagnosed worldwide each year. Its incidence increases with age and is currently rising. Although the increased availability of screening programs has allowed

Paclitaxel, a chemotherapeutic drug isolated from the Pacific yew, was approved for the treatment of metastatic breast cancer in 1994 and remains one of the most important agents in the treatment of patients with this disease. It is currently approved for the adjuvant treatment of node-positive

BACKGROUND In the treatment of advanced-stage ovarian cancer, it is common practice to treat elderly patients in a less aggressive fashion than young patients. This approach is based on the notion that age is associated with poor patient tolerance to aggressive chemotherapy. Relatively little data

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), a novel antitubulin agent derived from the bark of the Pacific yew tree, may be one of the most active single agents in our chemotherapy armamentarium. Concern over acute hypersensitivity reactions has resulted in an administration

Taxol (paclitaxel), a complex diterpene obtained from the Pacific yew, Taxus brevifolia, is arguably the most important new drug in cancer chemotherapy. The mechanism of cytotoxic action for paclitaxel-i.e., the stabilization of microtubules leading to mitotic arrest-is now shared by four recently

Paclitaxel (Taxol) is a diterpene originally obtained from the bark of the Pacific Yew Tree, Taxus Brevifolia. Its mechanism of action is unique. It stabilizes microtubule polymerization, thus blocking cells in the G2/M phase of the cell cycle. In breast cancer, initial studies using paclitaxel

Paclitaxel and docetaxel are antineoplastic drugs derived from the yew tree, Taxus brevifolia. They are the members of the taxane family and act by inhibiting mitotic activity due to the suppression of microtubule depolymerization. They are used in the treatment of ovarian cancer, breast cancer,

Paclitaxel (Taxol) a taxane antineoplastic agent causing irreversible microtubule aggregation with activity against breast, ovarian, lung, head and neck, bladder, testicular, esophageal, endometrial and other less common tumors was derived from the bark of the Pacific yew (Taxus brevifolia). Phase I

Head and neck cancer is a major cause of cancer-related deaths. In general, early stage head and neck cancers are effectively treated with either radiation or surgery. More advanced tumors often require combined-modality therapy with both radiation therapy and surgery. Recent investigations indicate

BACKGROUND Taxol, a complex plant product (a diterpene) extracted from the bark of Taxus brevifolia, has demonstrated substantial anticancer activity in ovarian and breast cancers, malignant melanoma, and acute myelogenous leukemia. Due to allergic reactions in phase I and early phase II studies,

Paclitaxel is a front-line agent for ovarian cancer chemotherapy, along with the platinum agents. Derived from the Pacific yew tree, Taxus brevifolia, paclitaxel has covered significant ground from the initial discovery of its antineoplastic properties to clinical applications in many forms of human

Paclitaxel, isolated from Taxus brevifolia, is considered to be an efficacious agent against a wide spectrum of human cancers, including human cervical cancer. However, dose-limiting toxicity and high cost limit its clinical application. Curcumin, a nontoxic food additive, has been reported to
