[Nowadays, cancer is one of the greatest challenges facing mankind. However, there is still no consensus among researchers regarding the antiquity of cancer. Written sources and paleo-oncological studies may help to answer this question. The aim of this study is to present data on the history of cancer based on historical sources, literature data and own research fi ndings. Early historical sources indicate that cancer was already known in antiquity. Paleopathological studies of animal and human fossils show that malignant bone tumors were present in ancient times, although the frequency of the disease was seemingly very low. The increasing number of unearthed fossils and the use of modern diagnostic tools have led to a rise of the number of diagnosed cancer cases. Our comprehensive paleo-oncological study, focusing on the occurrence and frequency change of malignant tumors in historic populations of Hungary was based on the analysis of skeletal remains belonging to 11,000 individuals dated from the Early Neolithic to the late medieval period. During the analysis macromorphological, modern imaging and histological methods were applied. As a result of the extensive investigations osteological evidences of malignant bone tumors were identifi ed in 39 cases. Neoplastic bone diseases were present in all studied historical periods and there were no differences in their occurrence and frequency between the different archaeological periods.]

[Geriatric oncology]

TELEKES András

[Geriatric oncology has an increasing role since in several types of cancer the median age at diagnosis is above 60 years of age. The treatment of elderly patients are frequently set back by prejudice, stereotypes and lack of information. All these lead to the fact that even in well-developed countries elderly cancer patients often do not receive the necessary treatments. This is even more true in poor-countries, where the fi nancial defi cit accumulated in health care is often attempted to be reduced by the treatment of elderly. If a paediatric oncology patient does not get suffi cient cancer treatment there is a fi erce protest, but everybody is silent if this occurs in the case of an 80 years old patient. For this unacceptable situation both authorities (fi nancing) and professional bodies (treatment, education) are responsible. Clinical data show that elderly cancer patients get the same benefi t of active oncology treatment, as younger ones. Age on its own does not contraindicate any cancer treatment. The aim of this review is to prove by data, that elderly cancer patients should also get active oncology treatment. The questions of assessment include frailty, the relationship of cancer development and ageing, and other problems related to the oncology treatment of elderly patients are also discussed.]

[Increasing experimental and clinical evidences demonstrated the synergic effect between the rapidly implemented immunotherapy and advanced forms of focal radiotherapy, not only on the elimination of the irradiated lesion, but also on the enhancement the immune-mediated systemic anti-tumoral activity. It is essential for gaining the most benefi t from the combination of the two modalities to select the appropriate patients, to defi ne the irradiation parameters, such as radiation quality (ie. particle) dosage, (total dose, fraction number) size of the target volume, the use of other supportive and anti-tumor drugs. In this review, we provide an update for the daily oncological practice on the data accumulated up to now on the molecular basis and patomechanism of enhancing radio-immune effect and clinical results, and highlight the most important parameters, which may increase the abscopal effect of ionizing radiation, thereby increasing the effectiveness of immunotherapy. However, development of clinical guidelines for benefi cial integration of immunotherapy and radiotherapy could be expected after evaluation the result of currently ongoing numerous (> 100) clinical trials. If the preclinical results will be confi rmed clinically, it could lead to paradigm shift in the use of ionizing radiation.]

[Obesity and cancer]

VALTINYI Dorottya

[The role of obesity in the development of cancer is well-known from ages. However, these days we witness the explosion-like increase of obesity, globally, but mainly in the economically advanced population, and, which is even more alarming, among youngsters. The prognosis of the obesity-related cancer is rather poor, therefore, the prevention, including the screening, have outstanding importance. Unfortunately, the participation of the obes persons, especially obes women, in these programs is very low. The diagnostics and therapies should consider the special features of obesity, which are related to the magnitude, distribution, composition of fatty tissue connected to the changes in pharmacokinetics. Moreover, the problems might be complicated with obesity-associated non-tumorous severe diseases (e.g. cardiovascular, diabetes type 2).This review covers different aspects of obesity-cancer relationships, with an emphasis on everyday oncology.]

[Pregnancy and cancer]

NAGY Zsuzsanna, SZILLER István, VALTINYI Dorottya, HORVÁTH Orsolya

[The joint appearance of pregnancy and cancer is rare. It is highly recommended that the tumorous pregnant should be managed by a multidisciplinary team. The early diagnosis is very important, but it is not easy, because the symptoms of pregnancy and cancer are rather similar. Imaging diagnosis has to avoid ionizing radiation (e.g. PET/CT). The same is true for chemotherapy in the fi rst trimester, due to the increased risk of developmental abnormalities. Consequently, radiation therapy is not allowded throughout the pregnancy, and the chemotherapy in the fi rst trimester is a strong indication for the interruption of pregnancy. Surgery, with good practice, usually can be performed without complications. Chemotherapy, given in the second and third trimester generally follows the standard protocols with a low frequency of developmental errors. Early delivery should not be encouraged, except the delay has a hazardous effect on the mother and/or on the child. The pregnant should be informed about all steps to be an active part of the fi nal decision.]

[MicroRNAs as a new family of hormones]

BOJCSUK Dóra, SIPOS Lilla, BÁLINT Bálint László

[MicroRNA molecules regulate the translation of mRNAs to proteins. In a study published by Maria A. Cortez and her colleagues in Nature in 2011, the authors suggest that miRNAs, known as biomarkers and translation regulators, could be considered as nucleic acid hormones. In this paper we introduce the characteristics of microRNAs that support their function as hormones.]

Purpose - In cancer patients, an ischemic stroke can be seen as both a direct effect of cancer and a complication of treatment. This condition can negatively affect the follow-up and treatment of these patients. For this research, we aimed to evaluate the clinical features, stroke types and etiological features of ischemic stroke patients with histories of cancer or found to have cancer during the aetiological investigation. Materials and methods - We retrospectively evaluated 100 patients (57 males, 43 females) who were hospitalized with acute stroke and determined to have the presence of cancer or a cancer history during the aetiological investigation between 2011 and 2016. All the demographic features, stroke types and localizations, National Institutes of Health Stroke Scale (NIHSS) scores, Rankin Scale scores, durations of cancer and cancer treatments were recorded. Results - The mean age of the patients was 67.07 ± 10.9 years old, the median NIHSS score was 5, and the median Rankin Scale score was 4. While 79% of patients had ischemic stroke risk factors, 21% did not. Atherosclerotic stroke was the most common stroke type (49%, n=49) and cryptogenic strokes were detected in 21% (n=21). In addition, 63% of the patients had chronic cancer (later than 6 months), 31% of the patients had recent cancer histories (less than 6 months), and 29% of the patients had metastases. Among all the malignancies, lung cancer (n=23), gastrointestinal cancer (n=20) and gynaecological-breast cancer (n=16) were the three most common. Moreover, 37% of the patients underwent chemotherapy, 29% underwent radiotherapy, and 88% of the patients had Carotid/Vertebral Doppler USG abnormalities. Conclusion - Similar to what is stated in the literature, an atherosclerotic stroke was the most common type of stroke in the cancer patients. Stroke risk factors were not detected in 21% of the patients, and in the majority of the patients, atherosclerotic changes in the carotid artery were observed in the Doppler examinations. In the aetiology and prognosis of ischemic stroke, it is important to keep in mind the existence of cancer in addition to the classical stroke risk factors.

[Inhibition of proteasome in cancer therapy]

KOPPER László

[The ubiquitin-proteasome pathway is the most important element in the regulation of intracellular protein metabolism. Its main function is the degradation of the unnecessary proteins either as part of normal metabolic balance or in case of misfolding or part of the deregulation as in cancer cells using proteolytic enzymes. The importance of this pathway has been acknowledge by Nobel prize. In certain diseases as in several malignancies, where the ubiquitin-proteasome pathway is not able to remove the proteins due to dysfunction or accumulation in a high quantity. The unregulated accumulation of proteins could lead to cell death. This phenomenon was proven by the appearance of proteasome-inhibitors targeting mainly myeloma. It should be mentioned that clinical aspects myeloma has been discussed in an excellent review by Mikala and his colleagues in Klinikai Onkológia.]
