Therapy-related leukemia or therapy-related myeloid neoplasm are widely-used terms to designate leukemia developing in persons who previously received anti-cancer therapy (for example, see references 1, 2), especially if the prior anti-cancer therapy included drugs such as alkylators, DNA-intercalators, topoisomerase-2-inhibitors, purines and/or ionizing radiations.   Sometimes specific genes such as AML1, EVI1, NRAS or MLL are mutated by therapy or gene variants are produced which activate mutagens or interfere with DNA repair, such FANC, NQ01 or AML2. 3-5   But how can we know if AML in someone is a therapy-related?Keywords: Therapy-related leukemia; alkylators; ionizing radiations; Topoisomerase Inhibitors; DNA Repair

Acquired Abnormalities

Inherited and acquired abnormalities in DNA damage repair system may lead to cancer and other diseases, as well as to act as one of the key factors determining the patient’s responsiveness to chemo- and radiotherapy. Nowadays, the principles of the personalized therapy, based on specific features of disease development and pathogenesis of a solitary organism or in a small group, are applied to treat a broad number of diseases, including cancers. This approach allows to choose the most effective cancer therapy in every single case of cancer, based on the genetic analysis and expression level of specific proteins. One of the promising approaches for increasing the effectiveness of non-surgical cancer treatments - to develop the methods to increase the cancer cells sensitivity to conducted chemotherapy, based on using the DNA repair system defects for the better anti-cancer effect. The review covers some types of DNA repair system defects occurring while chemo- and radiotherapy. Perspectives of the possible influences on DNA repair mechanisms treated as possible targets for both anti-cancer treatment and for increasing the effects of cancer chemo- and radiotherapy, are discussed in the review considering the available published data and results of own research. DNA repair system defects play an important role in cancer genesis, but as well can determine the good response of patients with such defects to chemo- and radiotherapy (inducing different types of DNA damage).

Cancerous Cells

Chemotherapy employs anti-cancer drugs to stop the growth of cancerous cells, but one common obstacle to the success is the development of chemoresistance, which leads to failure of the previously effective anti-cancer drugs. Resistance arises from different mechanistic pathways, and in this critical review, we focus on the Fanconi Anemia (FA) pathway in chemoresistance. This pathway has yet to be intensively researched by mainstream cancer researchers. This review aims to inspire a new thrust toward the contribution of the FA pathway to drug resistance in cancer. We believe an indepth understanding of this pathway will open new frontiers to effectively treat drug-resistant cancer.

Pharmaceutical Properties

Background: Essential oils are complex mixtures of low molecular weight compounds extracted from plants. Their main constituents are terpenes and phenylpropanoids, which are responsible for their biological and pharmaceutical properties, such as insecticidal, parasiticidal, antimicrobial, antioxidant, anti-inflammatory, analgesic, antinociceptive, anticarcinogenic, and antitumor properties. Cancer is a complex genetic disease considered as a serious public health problem worldwide, accounting for more than 8 million deaths annually. Objective: The activities of prevention and treatment of different types of cancer and the medicinal potential of essential oils are addressed in this review. Conclusion: Several studies have demonstrated anti-carcinogenic and antitumor activity for many essential oils obtained from various plant species. They may be used as a substitution to or in addition to conventional anti-cancer therapy. Although many studies report possible mechanisms of action for essential oils compounds, more studies are necessary in order to apply them safely and appropriately in cancer therapy.

Cancer is a leading cause of mortality worldwide, accounting for 8.8 million deaths in 2015. Among these, at least 0.78 million people died of liver cancer alone. The recognized risk factors for liver cancer include chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, exposure to dietary aflatoxin, fatty liver disease, alcohol-induced cirrhosis, obesity, smoking, diabetes, and iron overload. The treatment plan for early diagnosed patients includes radiation therapy, tumour ablation, surgery, immunotherapy, and chemotherapy. Some sort of drug delivery vehicles has to be used when the treatment plan is targeted chemotherapy. Nanoemulsions are a class of biphasic liquid dosage form which are mixtures of oil and water stabilized by a surfactant. They are either transparent or bluish in hue and serve as a wonderful carrier system for chemotherapeutic drugs. These vehicles have a particle size in the range of 20-200 nm allowing them to be delivered successfully in the deepest of tissues. Recent publications on nanoemulsions reveal their acceptance and a popular choice for delivering both synthetic and herbal drugs to the liver. This work focuses on some anti-cancer agents that utilized the advantages of nanoemulsion for liver cancer therapy.
