Unsaturated fatty acids as a co-therapeutic agents in cancer treatment

Chemotherapy is standard treatments for many malignancies. However, in most cases, this method is not able to induce apoptosis and in many cases, with cancer recurrence, leads to patient death. There are several procedure to control and suppress malignant cells, but among these methods, administration of ɷ-3 fatty acids and ɷ-6 fatty due to their destructive effects on cancer cells is more prominent. Many clinical studies have shown beneficial effects of ɷ-3 and ɷ-6 fatty acids in cardiovascular disorders, asthma, rheumatoid arthritis, osteoporosis and in most cancers such as colon, breast, prostate and other malignancies. Studies showed that polyunsaturated fatty acids (PUFAs) have a toxic effect on cancer cells. However, the exact mechanism of how ɷ- fatty acids affect cancer cells is still unknown. In this review alternative issues of malignancies co-treatments agents such as PUFAs have been studied. Also, the latest known PUFAs mechanisms on malignancies have been described.
