Abstract:


Gastric cancer is the second most common cause of cancer-related deaths in the world. The surgical management of the tumor is the best therapeutic option for gastric cancer patients. A combination of a heterogeneous distribution of genetic and environmental factors appears to be required to explain patients' poor prognosis. A search for targeted and molecular-based approaches is affected by the optimal gastric cancer drug management. The modern multidisciplinary approach in treating the pathology using worldwide prolongs the overall patient survival and decreases the rate of recurrence. An understanding of the mechanisms that underlie therapies will provide new insights into gastric cancer treatment. The improvement in medicine will probably be associated with a study of tumor biology, followed by a personalized and molecular-based approach development in anticancer drugs administration. The modern perspective in gastric cancer detection and treatment is the application of nanoparticles. Nanoparticles affecting the intensity of biological processes in cancer cells can be used to treat cancers to increase the effectiveness of anti-tumor therapy. Their cytotoxicity involves a wide range of pathological events. Their targets are the extracellular matrix degradation, epithelial-mesenchymal transition, tumor angiogenesis, tumor microenvironment modulation. It is accompanied by lipid peroxidation, apoptosis, and autophagic flux. Preliminary studies on the efficacy of nanoparticle use in cultured gastric cancers open new opportunities for anti-tumor treatment to overcome the toxicity of therapeutic agents and decrease the rate of resistance to anticancer drugs and therapies.
