Background: Tumor response after multimodality treatment using combination of radiation, chemotherapeutic drugs and hyperthermia usually assessed by parameters such as tumor growth delay, volume doubling time and regression response. The study herein was conducted to investigate the usefulness of micronucleus assay for assessing the multimodality treatment. Materials and Methods: The ...

Objective(s): Cisplatin-induced peripheral neuropathy is a debilitating side effect in patients receiving this drug.  Recent studies suggest hyperbaric oxygen (HBO) therapy as a new treatment approach for models of neural injury. The aim of the current study was to determine the protective effects of HBO preconditioning against peripheral neuropathy induced by Cisplati...

Background: Despite modern developments in its management, still major concerns remain about drug resistance in chemotherapy. Natural adjuvants combined with chemotherapy might be the answer. We examined the anti-cancer, anti-proliferative and synergistic effects of Sambucus nigra extract with cisplatin chemotherapy (CDDP) on MCF-7 and MDA-MB-231 human cancer cell lines. Methods: MCF-7 and MDA...

In the treatment of cancer patients, cisplatin (CDDP) exhibits serious cardiac and renal toxicities, while classical combinations related to CDDP are unable to solve these problems and may result in worse prognosis. Alternately, this study covalently conjugated 6-mercaptopurine (6MP) onto the surface of mercapto-modified mesoporous silica nanoparticles (MSNS) to form MSNS-6MP and loaded CDDP in...

The mechanism of resistance to cfj-diamminedichloroplatinum(II) (CDDP) is still controversial, although several kinds of processes have been proposed. For elucidation of the mechanism of CDDP resistance in CDDP-resistant human non-small cell lung cancer cells (PC-9/0.5, 7.1fold resistant), we examined the formation of DNA interstrand cross links (ICL), one kind of DNA damage induced by CDDP, it...

To elucidate the mechanism of the synergistic cytotoxicity of 5-fluorouracil (5-FU) and cis-diamminedichloroplatinum(II) (CDDP), we studied the interaction of these agents using a human squamous carcinoma cell line (HST-1). Exposure to 5-FU for 24 h and to CDDP for 1 h produced a 50% inhibitory concentration of 1.0 micrograms/ml (7.7 microM) and 2.5 micrograms/ml (8.3 microM), respectively. The...
