The role of a radiology assistant during a vacuum biopsy
BEDNÁŘOVÁ, Anna
In the Czech Republic, several screening programs are carried out. Mammography screening is a program that has the longest history in the Czech Republic and boasts very good results. The goal of this screening is to find a tumor in the breast that is still intangible and is only a few millimeters in size, and thus to provide the woman with ideal treatment results. The basic method of investigation that is used is mammography screening, after scanning, in case of a questionable finding, it is performed for subsequent examination of the breast by sonography, images with spot compression, CORE-CUT biopsy, vacuum biopsy and very occasionally, if indicated, magnetic resonance imaging. Vacuum biopsy (SVAB) is a breakthrough in the diagnosis of breast tumors. The goal of my bachelor thesis was to find out how often a breast examination is performed using a vacuum biopsy. The bachelor thesis is focused on the role of a radiological assistant in vacuum biopsy. The aim was also to find out the age structure of women and the correlation between malignant and benign findings. For age structures, the goal was also to determine by nonparametric testing the existence of a link to normal distribution. Operationalized hypotheses were formulated to meet the test and correlation objectives. For the bachelor thesis, the data was obtained from the central Medicalc archiving system at the EUC clinic in České Budějovice. Since this method is carried out at the EUC clinic for a short time, the data for the bachelor's thesis was drawn in the range of 2020-2021. By analyzing the data, it was found out that stereotactic vacuum biopsy (SVAB) was performed a total of 118 times during the above-mentioned period. The results showed that the examination of the breast by vacuum biopsy has clear indications. Mostly it is carried out to verify the formed calcifications in the breast, whether these calcifications have a benign origin, or are the beginning of an emerging malignant process. Further, the SVAB is performed to verify lesions that are visible on mammography images and do not have a clear ultrasound colerat, and thus it is impossible to perform a classical CORE-CUT biopsy.

Analysis of mortality from breast cancer in selected European countries
Rathouská, Michaela ; Burcin, Boris (advisor) ; Kučera, Tomáš (referee)
Analysis of mortality from breast cancer in selected European countries Malignant neoplasms are in most European countries the second most common cause of death. The aim of this work is to describe the evolution of mortality of women which is caused by breast cancer. It describes this evolution in the years of 1980-2007 in the Czech Republic, Great Britain and Sweden. Development of mortality is set into the broader connections with a mortality rate of more frequent causes of death and certain other neoplasms in women. Work analyzes mortality by age, the incidence, and it also shows screening programs and international comparisons. Part of this work also deals with risk factors, prevention and treatment options. In all analyzed countries in analyzed period there have been decline of mortality from neoplasm, while the incidence increased. There was a shift of mortality to higher age , particularly in relation to improving health care and its increasing availability. The incidence was observed moving from the oldest to the younger age group, especially in due to introduction of the national mammography screening.

Molecular characteristics of ductal carcinoma in situ, and their clinical impact
Böhm, Jan ; Zikán, Michal (advisor) ; Dundr, Pavel (referee) ; Strnad, Pavel (referee)
Objectives: Ductal carcinoma in situ (DCIS) is a non-invasive lesion of an increasing clinical importance. Individual risk assessment is essential for an optimal treatment. Our objective was to identify clinical and molecular characteristics of a subgroup of DCIS with an unfavorable prognosis. Methods: In a population study, we analyzed women with DCIS diagnosed within one mammography screening unit. In the experimental part of this work, we conducted a comparative analysis of five biological markers in normal tissue, DCIS and invasive breast cancer by means of gene expression analysis and analysis of loss of heterozygosity (LOH). Results: We demonstrated a high proportion of pure (no invasive component) DCIS (14.41%) of all breast lesions described as malignant. In our sample, we saw a homogeneous distribution of risk factors without noting a clear pattern identifying high-risk subtypes. We noted significant differences in clinical management of tumors with similar characteristics, which demonstrates the present state of limited use of clinical predictors. In the laboratory experiment, we showed differences in loss of heterozygosity (LOH) between DCIS and invasive breast cancer for BRCA1 (8.69% vs. 44.74%) and BRCA2 (9.52% vs. 45.0%). In contrast, we did not find any differences for p53 (31.82%...

Breast cancer prevention.
Svobodová, Karolína ; Kulhavá, Miluše (advisor) ; Strnadová, Alice (referee)
The theme of this thesis is Breast cancer prevention, specifically focusing on breast self- examination. The thesis is divided into a theoretical and an empirical part. The theoretical part deals with breast anatomy, risk factors, symptoms, diagnosis, treatment and prognosis of breast cancer. A substantial part of the thesis is concerned with prevention, which introduces women with breast self- examination in the next chapter. The empirical part is implemented by means of a questionnaire survey. Group of respondents consisted of 92 women. The aim of this thesis is to determine whether women are aware of breast self-examination methodology, whether they perform self- examination or not. And if they do not, then what is the reason. Finally, the thesis find out where women got information about metodology of breast self-examination from. Importance of the thesis lies in obtaining information about breast cancer flexible and promotion of knowledge of prevention. First of all it should motivate women to take care of themselves.

Primary and secondary prevention of breast cancer in women
WEISSOVÁ, Veronika
Breast cancer is the most common form of cancer in female population in the Czech Republic. In 2002 the Czech Republic joined most European countries and launched nation-wide mammography screening, enabling women to attend regular preventive examinations when they reach 45 years of age. In January 2014 they started to address women to invite them for preventive breast cancer examinations, as part of a nationwide information campaign. Mortality of this cancer has been decreasing in recent years, which can be explained by the increasing quality of treatment and earlier detection of the disease. Therefore, knowledge of primary and secondary prevention is very important. The theoretical part briefly describes the anatomy of female breasts, defines a malignant tumor, as well as epidemiological aspects of breast cancer. Another chapter is about prevention itself. In the secondary prevention I describe self-examination of breasts and the history and nature of mammography screening. I also present organizations implementing preventive programs aimed at breast cancer. The practical part includes research results, which were obtained through quantitative research questionnaires. The research group consisted of women who live in the Ústí region. The questionnaire consisted of 27 questions and was answered by a group of 150 women between 18 and 44 years old and 150 women over 45 years. I handed out these questionnaires in Ústí healthcare center and I also created an electronic questionnaire which I sent across social networks. Out of the 150 (100 %) questionnaires distributed in Ústí healthcare center, I got only 60 back and 58 of them were sufficiently completed for the needs of the research, the return was only 38.7 %. I received the remaining 242 questionnaires electronically. The aim of the study was to explore the awareness of risk factors of breast cancer of women in the Ústí Region and also to find out whether women in the Ústí region carried out self-examination of breasts and if women over 45 attended regular mammography screening. Based on my research aim I set out four hypotheses. Hypothesis 1: Women in the Ústí region are informed about the risk factors of breast cancer. Hypothesis 2: Women at the age of 18 to 44 in the Usti region are more informed about the risk factors of breast cancer than women in the age group over 45. Hypothesis 3: The difference in the frequency of breast self-examination among women in the age group 18 to 44 is statistically more significant than in women in the over 45 age group. Hypothesis 4: Attending mammography examination of women over 45 in the Ústí region rises according to their level of education. The results of testing my hypotheses show that women in the Ústí region are not informed about the risk factors of breast cancer. I assumed that awareness is higher among women in the 18 to 44 age group, but even this hypothesis wasn't proven. Awareness of risk factors is on the same level in category of 18 to 44 years as in women over 45 years of age. Regarding breast self-examination, women in the above 45 years old age group carry out self-examination more often than women 18 to 44 years old. Even the last hypothesis was not confirmed, attendance of mammography doesn't appear to depend on the education of women. Awareness of women needs to increase, especially in case of risk factors of breast cancer. Awareness increase could be achieved by greater information campaign on television, in newspapers, in businesses with high numbers of working women, or in secondary and higher education through various public lectures. Over 90% of women attend Mammography screening according to my research, which are laudable results. The fact that the actual self-examination of breasts isn't carried out at all by more than half of the women in the age group 18 to 44 is serious. This work could serve as teaching or study material to improve general knowledge of this topic.
