OBJECTIVE This study was designed to evaluate the efficacy and toxicity of topotecan hydrochloride, used singly or combined with other drugs in patients with recurrent advanced ovarian cancer. METHODS Eighteen ovarian cancer patients who had received cytoreductive operation 1 to 3 times and 8 to 18

BACKGROUND Neutrophilic eccrine hidradenitis (NEH) is a self-restricted inflammatory condition, usually secondary to chemotherapeutic agents and less frequently to other drugs such as zidovudine or various infections. NEH clinical features include erythematous, occasionally painful nodules and

The topoisomerase 1 (Top1) inhibitor has been reported to inhibit inflammatory genes induced by virus and protect mice from sepsis. Its role in acute lung injury (ALI) remains unknown. This study aimed to explore the effects of topotecan (TPT), a Top 1 inhibitor, in lipopolysaccharide

Evaluation of the nutritional and inflammatory status in cancer patients for the risk assessment of severe haematological toxicity following chemotherapy.

BACKGROUND The toxicity outcome of cancer patients receiving chemotherapy is difficult to predict. In this study the influence of malnutrition and inflammation on acute haematological toxicity was investigated. METHODS Between January 1999 and January 2000, 48 consecutive cancer patients experienced

DNA-Containing Exosomes Derived from Cancer Cells Treated with Topotecan Activate a STING-Dependent Pathway and Reinforce Antitumor Immunity.

Danger-associated molecular patterns derived from damaged or dying cells elicit inflammation and potentiate antitumor immune responses. In this article, we show that treatment of breast cancer cells with the antitumor agent topotecan (TPT), an inhibitor of topoisomerase I, induces danger-associated

UNASSIGNED PM01183 is a new compound that blocks active transcription, produces DNA breaks and apoptosis, and affects the inflammatory microenvironment. PM01183 showed strong antitumor activity in preclinical models of cisplatin-resistant epithelial ovarian cancer. UNASSIGNED Patients with

SN-38, the active metabolite of irinotecan, inhibits the acute inflammatory response by targeting toll-like receptor 4.

Anticancer-drug efficacy seems to involve the direct interaction with host immune cells. Although topoisomerase I (Top I) inhibitors have been suggested to block LPS-evoked inflammation, the interaction between these drugs and toll-like receptor 4 (TLR4) is

OBJECTIVE We investigated the effect of topotecan on injury and inflammation in a model of ventilator-inducedlunginjury (VILI). METHODS Acute lung injury (ALI) was induced in mice by high-tidal volume ventilation, and the mice were then treated with topotecan or PBS. Lung tissue and bronchoalveolar

Overexpression of IL-6 but not IL-8 increases paclitaxel resistance of U-2OS human osteosarcoma cells.

The cytokines IL-6, initially recognized as a regulator of immune and inflammatory response and IL-8, a potential regulator of angiogenesis, also regulate the growth of many tumor cells. Human cancer cells selected for multidrug resistance to common chemotherapeutic agents demonstrate increased

Activation of targeted necrosis by a p53 peptide: a novel death pathway that circumvents apoptotic resistance.

Cancer cells escape apoptosis by intrinsic or acquired mechanisms of drug resistance. An alternative strategy to circumvent resistance to apoptosis could be through redirection into other death pathways, such as necrosis. However, necrosis is a nonspecific, nontargeted process resulting in cell

Hypoxia-inducible factors (HIFs) are transcription factors that are expressed in the hypoxic tumor microenvironment. They are involved in the cellular adaptations by improving the metabolism of glucose and enhance the expression of vascular endothelial growth factor, platelet-derived growth factor

P-glycoprotein (P-gp), a member of ATP-Binding Cassette transporter superfamily, can expel a variety of anti-cancer drugs so that it impairs the effect of cancer chemotherapy and results in multidrug resistance (MDR). The P-gp inhibitors are important to circumvent MDR and improve efficacy of cancer

Retinoblastoma (RB) is a common malignant intraocular tumor primarily affecting children. Multidrug resistance (MDR) proteins (P-gp and MRPs) mediated chemoresistance have been considered as a major cause of treatment failure in treatment of RB. Ocular cells have shown good tolerability against

Cancer-related fatigue (CRF) is the most common psychosomatic distress experienced by cancer patients before, during and after chemotherapy. Its impact on functional status and Health Related Quality of Life is a great concern among patients, healthcare professionals and researchers. The primary

BACKGROUND Chemotherapy (CT) resistance in ovarian cancer (OC) is broad and encompasses diverse unrelated drugs, suggesting more than one mechanism of resistance. To better understand the molecular mechanisms controlling the immediate response of OC cells to CT exposure, we have performed gene
