[Choice of optimal adjuvant treatment has been based on present debates, doubts and commit offence against processing or existing evidences. Clinical research has been resulted changes and renewal of practice decisions continuously. 3rd Breast Cancer Consensus Conference held on Kecskemét last year corresponded by Hungarian experts of the fi eld has given up to date and well-defi ned guideline. Present paper try to give a summary of adjuvant treatment courses for early breast cancer in consideration of last results of research since then.]

[Combination of radiotherapy and immunotherapy]

HIDEGHÉTY Katalin, BRUNNER Szilvia, SZABÓ Zoltán Imre, SZABÓ Emília Rita, POLANEK Róbert, TŐKÉS Tünde

[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.]

[Signaling pathways in cancer stem cells (Notch, Hedgehog, Wnt)]


[OThe key regulators in the embryonic life, and later in the differentiation of tissues and organs are the evolutionary reserved signalling pathways, as Notch, Hedgehog and Wnt. Mutations of these pathways have been identifi ed in many tumor types, increasing the risk to the appearance of cancer stem cells (CSC), with very similar geno- and phenotype as normal stem cells have. Such CSCs with stemness functions can be developed not only from normal stem cells, but also from progenitor and differentiated cells. The main characteristics of CSC are the self maintenance, slow growth rate, very effective DNA-repair system, etc. All of these can contribute to the resistance. Further problems are the low number of CSC in the whole tumor mass, which makes rather diffi cult to achieve the effective drug concentration in CSC. The mentioned ancient pathways interact with many other pathways to form a network, which can infl uence the strategy of therapy. No doubt, that these pathways are promising targets, however, till now the clinical effectiveness is very low due to some reasons mentioned above. Nevertheless, some drugs are already in clinical use, either as monotherapy or part of the combinations. Little is known about the relationship between the pathways and the microenvironment, which has an outstanding role in the cellular activities, sometimes resulting opposite output. It is a great challenge to design effective drugs against CSC, similarly to fi nd reliable predictive biomarkers, which unfortunately still missing, since a reasonable drug-marker interactions would speed up the personalized treatment.]

[Paleo-oncology - messages from the past]

[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.]

[Fulvestrant: long-term survival and quality of life in a patient with hormone receptor-positive advanced breast cancer]


[INTRODUCTION - There are lot of evidence showing the efficacy of fulvestrant therapy in HER-2 negative, HR-positive advanced metastatic breast cancer. CASE REPORT - A 75-year-old female had a mastectomy, followed by series of adjuvant and radiotherapy about 30 years ago. Later cutan metastases were removed several times. The endocrine therapy had to be stopped because of intolerance. An ER, PR positive, HER-2 negative cutan metastasis was resected 7 years ago for the last time. During regular checkup, 5 years ago pulmonary nodule and bone metastases were found, - PET-CT disclosed multiple metastatic lymph nodes as well. We started fulvestrant and bisphosphonate therapy. Thereafter, as imaging revealed, the malignant disease has stabilized, the patient has a good performance status, her musculo-skeletal pain has a presumably degenerative origin. DISCUSSION - Reported case corroborates the potential efficacy of fulvestrant and ibandronate in hormone sensitive breast cancer with good prognostic markers, even in the case of metastases in soft tissue and bone. This case supports the data, that in patients with not progressive bone metastases the frequency of administration of parenteral bisphosphonates may be reduced to every 3 months. Advanced metastatic breast cancer may be converted to a chronic disease in properly selected cases, and it could mean long-term survival with a good quality of life.]

[Gene-expression profiles in adjuvant treatment of early breast cancer]


[Breast cancer is a heterogeneous disease with different subtypes having a distinct biological, molecular, and clinical course. Assessments of standard clinical and pathological features have traditionally been used to determine the use of adjuvant systemic therapy in early-stage breast cancer; however, the ability to identify those who will benefi t from adjuvant chemotherapy remains a challenge, leading to over treatment of some patients. Risk stratifi cation of patients with early stage breast cancer may support adjuvant chemotherapy decision-making. This review details the development and validation of seven multi-gene classifi ers, each of which claims to provide useful prognostic and possibly predictive information for early stage breast cancer patients. A careful assessment is presented of each test’s analytical validity, clinical validity, and clinical utility, as well as the quality of evidence supporting its use.]


[Osteonecrosis of the jaws: real and unreal scares]


[Osteonecrosis caused by bisphosphonates has been known for a long time, but it is still not widely known. Some people overestimate the danger caused by this disease, whereas others underrate it. In this paper, we summerise data from the international literature and our experiences concerning 93 patients treated at our clinic. We discuss the already known details of the pathomechanism of this disease, its risk factors, the diagnostic methods, the specific stages of the disease and the treatment approaches. Considering the difficulties of treatment, we can't emphasise enough the importance of prevention, since the development of this complication can be minimised even in patients at risk with dental sanation before the bisphosphonate therapy and/or with further intervention performed with antibiotic preventive therapy. We must also point out the importance of early diagnosis and of directing these patients to the appropriate specialist units.]


[Osteoporotic patient’s use of prescription drugs - pilot study]


[BACKGROUND - In Hungary, the number of the highest mortality hip fractures is between 12 000-15 000 per year. The cost of treating hip fractures is several times higher than that of preventive medical therapy. Thus, the compliance of patients with osteoporosis is of great importance. METHODS - Using the informatical database of St. András Rheumatology Hospital at Héviz, we collected one year’s prescription drugs for osteoporosis and compared them with the number of drugs obtained by the patients, determined from National Health Insurance data. RESULTS - In general, the patients obtained 75% of prescription drugs. From the 4354 boxes of prescribed antiporotics, 3637 contained bisphosphonate (not considering vitamin D and calcium). Within this group, 88% of combination preparations were obtained, which is a greater ratio than that of non-combination bisphosphonates (84%). CONCLUSIONS - On the basis of our results, we posit that prescription of a combination preparation somewhat improves the patients’ compliance. The low concordance of vitamin D and calcium preparations is worrying.]

[Bisphosphonates are used in the treatment of malignant diseases with bone metastases and of osteoporosis. The currently available bisphosphonates have a wide range of effectiveness, tolerability and dosing profiles. In metastatic disease, bisphosphonate therapy is aimed at the correction of hypercalcaemia and the reduction of skeletal-related events due to malignancy metastatic to bone. Large clinical trials have shown that long-term administration of bisphosphonates can reduce skeletal-related events by 30 to 40% and significant analgesic effect is reached in at least 50% of the patients. The superiority of zoledronate to the old standard pamidronate has been proved in large randomized trials. Despite the fact that bisphosphonates are generally well tolerated, certain toxicities such as renal toxicity and osteonecrosis of the jaw should be considered with prolonged use.]
