[Treatment of anemia in cancer patients]

NAGYKÁLNAI Tamás

[Anemia in cancer can be resulted by the underlying malignant disease or related to the chemotherapy. Cancer-related anemia adversely effects quality of life and is associated with reduced survival. Clinical studies demonstrate that blood transfusions, ESAs, and correction of iron defi ciency are therapeutic options for anemic cancer patients.]

[Side-effects of immunotherapy]

LANDHERR László

[The immune system has an important role in controlling and eradicating cancer cells. Antibody therapy against several negative immunologic regulators (checkpoints) has demonstrated promise in a variety of malignancies. The immune checkpoint blockade with antibodies against cytotoxic T lymphocyte- associated antigen 4 (CTLA-4) and the programmed cell death protein 1 pathway (PD-1/PD-L1) and its ligand have a unique and distinct pattern of adverse events. Immune-related adverse events are most commonly observed in the skin, gastrointestinal tract, liver and the endocrine system. Early recognition and treatment are believed to be important in mitigating severity of such adverse effects.]

[Long-term central venous access devices in oncology]

PAJKOS Gábor

[Long-term central venous access devices are essential in the management of oncology patients, as they minimize the discomfort caused by frequent venipuncture and cannulation. Indications of application of central venous accesses, possibilities of implantations, immediate and long term complications, they prevention and obviation has been reported based on guidelines and relevant publications. Long term implantable central venous accesses handled by well-trained and exercised team, working with principles of maintenance, these manipulations are effective and safe, therefore suitable in oncological practice.]

[Defi ciency of DNA-repair]

KOPPER László

[The cell uses the DNA to keep those information, which are vital to function properly. It is essential to maintain the integrity of the DNA, the stability of the genome. Since DNA damages, caused by external or internal factors, are continuously produced, DNA-repair mechanisms should be ready to identify and eliminate the damages. Either the repair system is successful and the cell can continue its duty, or, if the damages are unrepaired, the programed cell death (apoptosis) is activated according to the rule, that it is prohibited to transfer genomic/epigenomic damages into the daughter cells. It is true that the severness of the damages are not the same. The most important is the identifi cation and repair of those damages which can make genomic instability increasing the risk of cancer development. This may happen when the repair system is insuffi cient, sometimes due to inherited mutations (e.g. BRCA1 mutations can increase the risk of breast cancer, ovarian cancer etc.). Among the damages the DNA double strand breaks are rather common, and also, that the breaks are intended to be repaired in most cases. However, if such repair fails, the cell, here the cancer cell, due to the overhelming damages will dye. This phenomenon is the synthetic lethality. An example: „cooperation” of inherited BRCA1 mutation and PARP-inhibition, can lead to clinical response using PARP inhibitors, as oliparib. New agents and clinical trials intend to take advantage from synthetic lethality.]

[Sándor Gerő, the researcher clinician (1904-1992)]

GÁCS János

[Sándor Gerő presents two theories concerning the origin of atherosclerosis. The first one is called “primary lipid infiltration concept” which means the penetration of high concentration plasma lipids into the arterial wall without its damage. The other theory for the origin of atherosclerosis is primary damage of the vascular wall (namely of fibers, mucopolysaccharid etc.) which is followed by lipid infiltration. In the literature it is named “primary vascular concept” of atherosclerosis. The author investigates the two possibilities with experimental and clinical methods and concludes that primary vascular damage is more probable to be the origin of atherosclerosis.]

[NEW MODALITIES IN THE TREATMENT OF CHRONIC VIRAL HEPATITIS C: PEGYLATED INTERFERONS]

GERVAIN Judit, NEMESÁNSZKY Elemér, CSEPREGI Antal

[Interferon-α proved to be the most effective therapy of chronic hepatitis C. Its combination with ribavirin enhances the antiviral activity and this modality has become the therapeutic standard recommended worldwide during the past few years. Metaanalysis of the international studies revealed that only 12-19% of the patients became virus-free following a 48-week long course of α interferon monotherapy. The combination treatment with ribavirin for 48 weeks increased the proportion of sustained responders to 35-45%. The introduction of pegylated interferons resulted in significantly higher response rates. The new therapeutic possibilities are due to the modified pharmacokinetic characteristics of the drug by changing the size and the structure of the molecules. Multicentre studies investigating the clinical effectiveness of the 40 kD sized pegylated interferon α-2a as well as the 12 kD sized pegylated interferon α-2b in combination with ribavirin reported 56% and 54% response rate, respectively. However, there is significant heterogeneity in the results according to the type of drug administered and to the genotype of the hepatitis C virus, as well as in the basal viral level and the stage of hepatic fibrosis, respectively. The message and the conclusion of the viral kinetic studies are worth remembering: if the result of the HCV nucleic acid test is still positive at week 12 or 24, therapy should be ceased due to the patient non-responder status. Since pegylated interferons are also available in Hungary the authors felt useful to give an overview of the current knowledge, summarizing the results of the relevant studies and provide a suggested state-of-the-art therapeutic protocol based on international consensus.]
