[Primary systemic therapy (PST), also called as neoadjuvant therapy has a substantial role in the treatment of patients with breast cancer. There is an increasing need among clinicians for the monitoring of therapeutic effectiveness. Beyond simple physical examination, diagnostic imaging tools have the most important role in the measurement of the therapeutic response. Selecting the appropriate imaging method is crucial for the correct evaluation of the therapeutic response and for planning further therapy. In this paper we review breast imaging modalities currently available in Hungary and detail the efficiency of these modalities in the evaluation of the therapeutic response.]

[The role of hepatitis C virus in the development of non-Hodgkin lymphomas]

SULYOK Mihály, MAKARA Mihály, ÚJHELYI Eszter, VÁLYI-NAGY István

[There is a growing body of evidence for the association between chronic hepatitis C virus infection and certain subtypes of Bcell non-Hodgkin lymphoma. The development of a lymphoid malignancy is usually preceded by cryoglobulinaemia. Here, we summarise the most important epidemiologic data, and the possible molecular mechanisms of HCV-associated lymphomagenesis. The direct oncogenic effect of the virus has not been proven, but chronic antigenic stimulation maintained by replication and viral lymphotropism might both contribute to the development of lymphomas. It should be emphasised that elimination of the hepatitis C virus can halt this process in case of cryoglobulinaemia and low-grade malignity (usually marginal zone lymphomas). In these cases, antiviral therapy might be a useful alternative of conventional immune-chemotherapy. Thus, a collaboration between haematologists and hepatologists might be a great step forward in the treatment of these diseases. It is still not established whether interferon-based short-course therapies and interferon-free regimens are also effective in the treatment of associated lymphomas.]

[Meet the new member of the alprazolam family]

FERENCZ Csaba

[The struggle against anxiety disorders and symptoms of anxiety is as old as the history of human healing. The development of anxiolytics has constituted an important field of pharmacology from the very beginning. The appearance of benzodiazepines and high-potential benzodiazepines, developed as a later evolution of the former compounds, is considered a milestone in this battle. Today alprazolam is their most widely-used representative that can be considered a golden standard. Besides its agent, the formulation of the drug is also significant, as it helps in the administration, absorption and bioavailability of the agent and even for the establishment of good compliance. Nowadays we can witness the development of medicine families containing the same active ingredient and consisting of various products. In the case of alprazolam, we can welcome a new member of the family following the immediate-release tablets and the extended-release tablets. The aim of this paper is the introduction of the new member of the alprazolam family: the sublingual tablet.]

[Analysis of the knowledge on cervical cancer and attendance indicators of cervical screening]

VAJDA Réka, KARAMÁNNÉ Pakai Annamária, ÉLIÁS Zsuzsanna, SÉLLEYNÉ Gyuró Mónika, TAMÁS Péter, VÁRNAGY Ákos, KÍVÉS Zsuzsanna

[OBJECTIVE - The study aims to explore knowledge on cervical cancer and cervical screening among women with 9-14 yearold daughters, and learning the attitudes towards screening, the motivation of attendance at or absence from screening. DATA AND METHODS - A quantitative, cross-sectional study was conducted using our own questionnaire in the town Nagyatád in 2012. Study participants included women who had 9-14 year-old daughters and a registered home address in Nagyatád. We received valid responses from 186 people (response rate: 75.3%). RESULTS - The interviewed women’s knowledge on cervical cancer differed significantly depending on their age, education, marital status, and economic activity. Only 45 women with higher education (p=0.043) were considered to be well informed on the subject. However, their willingness to participate in cancer screening was more favorable than their knowledge, 96.2% of the women claimed to attend an annual cancer screening. The average age of respondents was 20.92 years at first visit. CONCLUSIONS - Although the participation rate was much higher compared with that in previously published studies, it is of great importance to increase the mothers’ knowledge on cervical cancer and the factors that promote its development, so that they can pass their knowledge to their children and strengthen their protection against one of the most common sexually transmitted viral infection and the development of cervical cancer.]

[Neoadjuvant therapy in breast cancer – an update]

KAHÁN Zsuzsanna, RUSZ Orsolya, UHERCSÁK Gabriella, NIKOLÉNYI Alíz

[Traditionally, neoadjuvant systemic therapy (NST) serves as treatment of advanced breast cancer to achieve technical operability by resulting in tumor regression. Nowadays, NST is advantageous in all cases if adjuvant systemic therapy is needed, since the in vivo study of its effect provides possibility for the estimation of prognosis, the treatment may be modifi ed according to the therapeutic response, the systemic therapy starts earlier as compared to adjuvant therapy, and fi nally, it may result in the reduction of surgical and radiotherapeutical radicality. The type of NST should be selected on the basis of tumor features refl ecting treatment sensitivity. In case of chemosensitive cancers, chemotherapy is taxane- and anthracycline-based, and the planned dose should be delivered prior to surgery. In HER2-positive cancers, the addition of an anti-HER2 agent doubles the rate of pathological complete regressions. In hormone-sensitive tumors, the standard neoadjuvant endocrine therapy consists of an aromatase inhibitor (postmenopause), or tamoxifen or an aromatase inhibitor combined with an LHRH analog (premenopause) for 4-8 months that is continued following the surgery in the adjuvant setting. For the early evaluation of the effect of NST, serial tumor biopsy or imaging studies (MRI, PET) seem promising. Sentinel lymph node biopsy around the NST should be practiced with prudence; it may warrant the avoidance of axillary blockdissection in some cases. For the design of radiotherapy, the initial stage and the degree of regression are considered.]

[The clinical importance of HER2 expression in breast cancer]

KAHÁN Zsuzsanna

[HER2 (neu/c-erbB-2) is a member of the EGF receptor family. It is activated without binding a specific ligand that leads to malignant transformation and tumor progression. Overexpression of HER2 is detected in approximately one quarter of human breast cancers. Immunohistochemistry and in situ hybridization (FISH) are the most widely used techniques in studying HER2 expression. HER2 positivity indicates worse outcome in node positive breast cancer and increasing number of studies show unfavourable prognosis in node negative cases as well. Recent data indicate that the knowledge of HER2 status may promote therapeutic decision. The generally applied cyclophosphamide- methotrexate-5-fluorouracil (CMF) polychemotherapy seems to provide no benefit in HER2 positive cases in contrast with HER2 negative breast cancer patients. Interestingly, doseintensive doxorubicin based chemotherapy gives better results in HER2 positive than in HER2 negative tumors. Determination of HER2 expression has great importance before therapeutic application of the humanized antibody trastuzumab (Herceptin). HER2 overexpression usually correlates well with estrogen and progesterone receptor negativity and hormone-resistance, therefore hormonal therapy is not justified for these patients. Some experimental and clinical data indicate that in case of simultaneous HER2 and ER positivity tamoxifen worsens treatment results which may be prevented by the coadministration of tamoxifen and trastuzumab. Emerging experimental and clinical data about HER2 has led to a new stage of individual treatment of breast cancer patients. The knowledge of HER2 status promotes antitumor intervention based on molecular characteristics of breast cancers. Therefore, reliable HER2 tests are needed in the everyday practice.]

[Results of non-operative pathological breast diagnostics - One year experience at the Bács-Kiskun County Teaching Hospital]

CSERNI Gábor, AMBRÓZAY Éva, SERÉNYI Péter, BORI Rita, LŐRINCZ Margit, LÓRÁND Katalin

[INTRODUCTION - Non-operative cytological and histopathological assessment of breast lesions are part of the triple (physical, imaging and pathologic) diagnostic approach and allow a more precise planning of surgical procedures. Both methods have advantages and disadvantages; currently, core biopsy is believed to be more efficient in reaching the diagnostic target. PATIENTS AND METHODS - Breast specimens with a histological diagnosis at the Department of Pathology of the Bács-Kiskun County Teaching Hospital were analysed for their preoperative pathology, using the conventional C1-5 and B1-5 diagnostic categories. RESULTS - 295 cytology and 130 core needle biopsy cases were analysed. The rate of non diagnostic (C1 and B1) material was higher for cytology (0.18 versus 0.08 in general; 0.09 versus 0.01 for malignant cases). The rate of cases with an uncertain diagnostic category (C3 and C4 or B3 and B4) was also higher for the cytology specimens (0.24 versus 0.07). False-negative and false-positive cases were rare, but still more frequent among cytology specimens. CONCLUSION - Core needle biopsy performs better than fine needle aspiration cytology in the establishment of a nonoperative diagnosis at our institution. Despite these results, cytology continues to be the first diagnostic choice, because of its relatively low costs.]

[Surgical view on the perioperative oncological treatment of liver metastases originated from colorectal cancer]

KUPCSULIK Péter

[Recent development of surgery resulted in fundamental changes in assessment of resectability of liver tumors. Surgical interventions became more radical and more effective. Colorectal liver metastasis (CLM) represents the most frequent hepatic tumor, where therapeutic options require close collaboration between surgeons and oncologists, and up-to-date approach from both. As the fact is, that CLM is a metastasis of a primary colorectal carcinoma, it seems to be obvious to apply perioperative chemotherapy. Results justify serious precaution. Neoadjuvant chemotherapy did not improve overall survival. Several data testify, that even perioperative chemotherapy is not indicated in these cases. Adjuvant chemotherapy can be applied after extended liver resections and two stages hepatectomies. About 20% of patients with initially inoperable CLM may be rendered resecable after systemic chemotherapy. Prognosis of synchron CLM is bad, 5 year survival is less than 20%. Disappearing CLM needs special respect, high level of perfection in liver surgery is essential. After chemotherapy postoperative morbidity is rising, technical diffi culties may occur. Further studies are required to examine possible effect of new targeted molecular therapy-based regimens on resectability. Individualized multidisciplinary treatment planning is mandatory.]

[INTRODUCTION - Carcinomatous meningitis is a serious complication of advanced stage solid tumours, which may become more common with improved survival. CASE REPORTS - A 53-year-old woman with a recent history of breast cancer (pT2pN2M0) had been treated by mastectomy and adjuvant chemotherapy and radiotherapy. She presented with weakness, diplopia and vertigo raising the possibility of vertebrobasilar ischaemia or an intracranial mass. In another patient, a 62-year-old man with hypertension, a stenotic common bile duct had been diagnosed when examined for abdominal complaints. When he presented with a high blood pressure value accompanied by intensive headache, vomiting and bilateral hearing loss, he was thought to have a hypertensive crisis. The rapidly progressive neurological symptoms and the history of breast cancer and findings suggesting pancreatic head tumour, respectively, led to the clinical diagnosis of carcinomatous meningitis in both cases, despite any evidence on CT scans or a negative MR scan, though of limited value, in the first case. This diagnosis was confirmed by the laboratory and cytological findings of the cerebrospinal fluid, and also by the post mortem examination, since both patients died within a month after the onset of the symptoms. The primary tumour in the second patient proved to be a widely metastasizing diffuse type gastric cancer. CONCLUSION - Carcinomatous meningitis has a varying but characteristic presentation which generally makes it easy to diagnose, but it can sometimes present differential diagnostic problems. What we can learn from these two cases may help in recognizing this complication.]
