Cisplatin Properties in a Nanobiotechnological Approach to Cancer: A Mini-Review.

For many years, cisplatin has been used to treat many types of cancer, including urogenital, skin and lung cancers. Unfortunately, treatment with this drug causes serious side effects, such as severe toxicity; including nephrotoxicity, neurotoxicity, gastrointestinal toxicity, peripheral neuropathy, ototoxicity, asthenia and hematological toxicity.Therefore, the clinical use of cisplatin has been hampered.The incidence of nephrotoxicity frequently prevents the use of high enough doses to maximize the antineoplastic effects, and strict attention must be given to the hydration of cisplatin-treated patients to minimize kidney damage.Nanobiotechnology, or nanomedicine, was developed to mitigate, or even eliminate,the toxic effects of pharmaceutical compounds; for example, drug-targeting systems were developed to enable site specificity and to control the delivery drug. Therefore, biomedical nanotechnology researchers attempted to develop nanostructures not only to deliver chemotherapeutics to the desired treatment site but also to control when and how quickly the compounds are released. To achieve these ends, a drug can either be encapsulated in a matrix or attached to a particle surface. Studies concerning the encapsulation of cisplatin in liposomes, polymeric nanoparticles, solid lipid nanoparticles and carbon nanotubes, as well as the immobilization of cisplatin on metallic nanoparticles, have already been published. The association of cancer treatment, particularly chemotherapeutics, with nanotechnology is currently one of the most exciting areas of research. In this mini-review, cisplatin will be discussed in terms of its efficacy against many cancers, including bladder cancer. Additionally, established nanostructure-based drug delivery systems for cisplatin and their efficacy against different types of cancer will be reviewed. Because cisplatin is a standard treatment with good performance statistics and with an effective renal function-glomerular filtration rate, we expect that this review will be helpful for future research.
