Opis:
Lung cancer is one of the most lethal types of cancer due to a lack of proper treatment. The rare presence of molecular therapy targets forces the use of platinum-based drugs. Cisplatin, approved by the USA as an anticancer therapy in the 1970s, is still one of the most prominent therapies against lung cancer. Unfortunately, the biggest limitation of cisplatin-based therapy is the development of cisplatin resistance. Cancer cells overcome the vast DNA damage caused by the drug in a variety of ways such as detoxication and extracellular transport of the drug, enhanced repair mechanisms, omitting apoptosis and epigenetic alterations. Chemotherapy resistance is an issue that so far cannot be dealt with. Nevertheless, better understanding of the molecular pathways behind cisplatin resistance brings hope for better therapy outcomes in lung cancer patients.

Opis:
Platinum drugs belong to one of the oldest [2] and best investigated groups of cytotoxic drugs. On account of their high efficacy and alkylating-like action [14] they are used in a treatment of various types of neoplasms [3–5]. Despite investigators’ best efforts survival time of patients diagnosed with cancer is still short. Responsible for the fact is high toxicity of used therapeutic methods and development of resistance to them [3–5, 19]. In this paper authors review reasons behind decreased sensitivity of neoplastic cells to platinum treatment and discuss the newest promising trends in its overcoming. Due to different properties of neoplastic cells, availability of a chemotherapeutic agent inside a tumour is limited [9–12]. Moreover continuous development of resistance to platinum drugs further decreases their cellular concentration and inactivates their functions. Also owing to increased activity of DNA repair systems, higher tolerance to genome deformations and numerous mechanisms that lead to impaired apoptosis, drug efficacy is reduced [3-5, 19]. In order to increase a potency of platinum agents new therapeutic strategies are investigated. Coadministration with resistance modulators [20, 22, 23] and combination therapy with other antineoplastic drugs [8, 24–30] have already proved their effectiveness. Additionally, newer generations of platinum drugs are developed [15–18]. Mostly platinum(IV) prodrug complexes often releasing axial ligands with their own pharmacological action [5, 6, 31], but also multi-nuclear platinum compounds that form more complex DNA-adducts [32–35]. Other strategies include the development of innovative dosage forms such as single walled carbon nanotubes (SWCNTs), multiwalled carbon nanotubes (MWCNTs) [38, 39] or encapsulation [36, 37]. Finally utilisation of oncolytic viruses could be a way to selectively destroy neoplastically transformed cells [40].
