Opis:
Breast cancer is the most common cancer among females worldwide. The mean age of breast cancer patients is > 60 yrs old, and it is seldom found in women < 40 yrs old (6.5%) and in very young women < 35 yrs old (0.6%). In young females, fertility and all its aspects are an additional therapeutic challenge. Before initiating treatment, the oncologist should offer effective contraception to be applied throughout the therapy, bearing in mind that fertility preservation is of utmost importance. When it comes to breast cancer in pregnancy, the attending physician should use a therapy which is safe for both the mother and the foetus. Chemotherapy, radiotherapy, hormonal therapy and immunotherapy can, to a lesser or greater degree, damage the ovarian function resulting in amenorrhea in women < 50 yrs (33–76%). However, owing to fertility preservation strategies, more and more pregnancies are successful, even in breast cancer survivors.

Opis:
In only the past century, the landscape of breast cancer treatment has completely changed. The Halstedian hypothesis of the “contiguous spread” of breast cancer has been replaced by a consideration of its systemic nature. Today, patients with early-stage breast cancer are managed with breast-conserving therapy, which is as effective as mastectomy. Sentinel lymph node biopsy has largely replaced axillary lymph node dissection. Post-operative radiotherapy, chemotherapy and endocrine therapy have increased survival. Pre-operative cytotoxic therapy allows for less extensive surgery and for a curative resection even in more advanced stages. Rapid progress in molecular oncology revealed a large heterogeneity of breast cancer, resulting in a more personalized approach. Targeted therapies directed against epidermal growth factor receptor type 2 (HER2) have improved survival in HER2-positive breast cancer, which was once a poor-prognosis entity. Multi-gene prognostic signatures better predict prognosis and allow many patients to avoid chemotherapy. Personalized treatment has resulted in decreased toxicity and an improved quality of life. Within the past decades, breast cancer has become a good-prognosis malignancy with a five-year survival in the range of 80-85%. Future development of personalized medicine may further refine treatment based on the tumor’s molecular features.

Opis:
Ultrasound is used for breast cancer detection as a technique complementary to mammography, the standard screening method. Current practice is based on reflectivity images obtained with conventional instruments by an operator who positions the ultrasonic transducer by hand over the patient’s body. It is a non-ionizing radiation, pain-free and not expensive technique that provides a higher contrast than mammography to discriminate among fluid-filled cysts and solid masses, especially for dense breast tissue. However, results are quite dependent on the operator’s skills, images are difficult to reproduce, and state-of-the-art instruments have a limited resolution and contrast to show micro-calcifications and to discriminate between lesions and the surrounding tissue. In spite of their advantages, these factors have precluded the use of ultrasound for screening. This work approaches the ultrasound-based early detection of breast cancer with a different concept. A ring array with many elements to cover 360. around a hanging breast allows obtaining repeatable and operator-independent coronal slice images. Such an arrangement is well suited for multi-modal imaging that includes reflectivity, compounded, tomography, and phase coherence images for increased specificity in breast cancer detection. Preliminary work carried out with a mechanical emulation of the ring array and a standard breast phantom shows a high resolution and contrast, with an artifact-free capability provided by phase coherence processing.

Opis:
The aim of this work is to create a web-based system that will assist its users in the cancer diagnosis process by means of automatic classification of cytological images obtained during fine needle aspiration biopsy. This paper contains a description of the study on the quality of the various algorithms used for the segmentation and classification of breast cancer malignancy. The object of the study is to classify the degree of malignancy of breast cancer cases from fine needle aspiration biopsy images into one of the two classes of malignancy, high or intermediate. For that purpose we have compared 3 segmentation methods: k-means, fuzzy c-means and watershed, and based on these segmentations we have constructed a 25–element feature vector. The feature vector was introduced as an input to 8 classifiers and their accuracy was checked. The results show that the highest classification accuracy of 89.02 % was recorded for the multilayer perceptron. Fuzzy c–means proved to be the most accurate segmentation algorithm, but at the same time it is the most computationally intensive among the three studied segmentation methods.

Introduction. Breast cancer is the second most prevalent reason for cancer deaths after lung cancer. Incidence rates have increased worldwide. Aim. To present epidemiology of breast cancer in Podkapackie voivodship. Material and methods. This analysis was performed using a systematic literature search. Results. In the Podkarpackie voivodship up until 2014, the incidence rate of female breast cancer was rising and in 2015 it dropped by 68 cases. Even though the survival rate is increasing, it is still one of the leading causes of cancer deaths placing second after lung cancer. Conclusion. Mortality rate, unfortunately, rose gradually. This shows that even though there is a National Health Program aiming at breast cancer awareness and prevention, it is still not enough to reduce the number of breast cancer deaths.

Introduction. Breast cancer is the most common cancer among women and is the second cancer frequently occurring worldwide of newly-diagnosed cancers. There is much evidence showing the influence of life style and environmental factors on the development of mammary gland cancer (high-fat diet, alcohol consumption, lack of physical exercise), the elimination of which (primary prevention) may contribute to a decrease in morbidity and mortality. Secondary prevention, comprising diagnostic tests (e.g. mammography, ultrasonography, magnetic resonance imaging, breast self-examination, as well as modern and more precise imaging methods) help the early detection of tumours or lesions predisposing to tumours. Objective. The aim of this study paper is to review current knowledge and reports regarding primary and secondary prevention of breast cancer. State of knowledge. It is estimated that nearly 70% of malign tumours are caused by environmental factors, whereas in breast cancer this percentage reaches 90–95%. There are national programmes established in many countries to fight cancer, where both types of prevention are stressed as serving to decrease morbidity and mortality due to cancers. Conclusions. Cancer prevention is currently playing a key role in the fight against the disease. Behaviour modification, as well as greater awareness among women regarding breast cancer, may significantly contribute towards reducing the incidence of this cancer. Another important aspect is the number of women undergoing diagnostic tests, which still remains at an unsatisfactory level.

It can facilitate breast conservation therapy. Response to NCT is a strong predictor of outcome breast cancer (BC). Direct target therapies has markedly improved the result of treatment BC. Aim. Therapy for breast cancer continues to improve. The importance of tumor burden on local control rates will be in the future. Material and methods. This analysis was performed using a systematic literature search. Results. The latest scientific reports give hope for greater safety and a better life for patients based on optimized and effective therapy. Conclusion. Currently, improving the effectiveness of breast cancer treatment is mainly related to the optimal use of classic therapeutic strategies. New classes of substances have been approved for treatment or are in advanced stages of clinical development.

Breast cancer and following demanding oncological treatment extensively influence life of female patients. It intervene biological, psychical and social life of patient. Objective of our research was to check how women are informed about preventive precautions and how they are following them. Our research sample were randomly selected women of all age groups. Our results showed that it is necessary to increase activity in the area of education, increase personal responsibility in area of breasts self-examination and better inform about the influence of obesity to breast cancer incidence. Considering our previous experience in health care we were surprised that the role of nurse in education process is very low. We think that general nurses have enough opportunities to use daily contacts with patients to inform and lecture them.

Opis:
Breast cancer is one of the most common malignancies across the world, including Poland. Chemotherapy plays an important part in the treatment of the disease. Most of the available chemotherapy drugs and regimens have undergone randomized clinical studies and have been registered for that specific indication. However, a number of drugs are used in an off-label manner, i.e. outside the officially approved product specifications. The paper discusses the use of several off-label therapies in breast cancer in order to demonstrate that such treatment may be well-grounded and indeed turns out beneficial in many cases. It describes the use of liposomal doxorubicin in pre- and post-operative treatment, capecitabine for incomplete efficacy of preoperative treatment, and the administration of metronomic vinorelbine. Moreover, the paper is aimed at demonstrating the legal basis and the principles of marketing authorization of off-label drug use.

Opis:
Introduction. Despite great progress in the diagnostics and treatment, breast cancer still remains the most frequently diagnosed malignant cancer in women. The outcomes of cancer treatment depend, to a considerable extent, on the degree of acceptance of the illness. The objective of the study was determination of the level of acceptance of the disease among the examined women with breast cancer. Materials and method. The study covered a group of 231 women who received treatment for breast cancer in the Rev. Bronislaw Markiewicz Subcarpathian Oncology Centre in Brzozow, south-eastern Poland, and conducted by the method of a diagnostic survey, using an author constructed questionnaire and the standard Acceptance of Illness Scale, adapted by Z. Juczyński. Statistical analyses were performed using the software IBM SPSS v. 21.0.0.1. The p values p≤0.05 were considered statistically significant. Results. The mean level of acceptance of the illness in the examined group of women was 26.53 (SD = 7.71; Me = 26). The largest number of respondents (50.6%) obtained scores within the range of 20–29, according to the AIS Scale. From among the adopted variables, the level of acceptance of the illness significantly varied according to age and occupational activity. However, no such differences were confirmed according to the place of residence, marital status, education level, or the type of occupation performed. Conclusions. In the examined group of women, a mediocre level of acceptance of cancer was observed. The respondents’ age and occupational situation exerted a significant effect on the level of acceptance of the illness. The results of the study should be considered as satisfactory because the number of women with a high level of acceptance of breast cancer was more than twice as high as those ones with a low acceptance of the disease.

Opis:
The paper provides a preview of some work in progress on the computer system to support breast cancer diagnosis. Diagnosis approach is based on microscope images of the FNB (Fine Needle Biopsy) and assumes distinguishing malignant from benign cases. Studies conducted focus on two different problems, the first concern the extraction of morphometric parameters of nuclei present in cytological images and the other concentrate on breast cancer nature classification using selected features. Studies in both areas are conducted in parallel. This work is devoted to the problem of feature selection from the set of determined features in order to maximize the accuracy of classification. Morphometric features are derived directly from a digital scans of breast fine needle biopsy slides and are computed for segmented nuclei. The quality of feature space is measured with four different classification methods. In order to illustrate the effectiveness of the approach, the automatic system of malignancy classification was applied on a set of medical images with promising results.

Opis:
Electrochemotherapy is a local therapy method reserved for cases not subject to surgery in advanced surface-localized cancers in the integuments. It may be applied in treating primary skin neoplasms (cancer and melanoma) as well as metastases of other neoplasms to the skin/hypodermis not qualified for another therapy (e.g. local removal or isolated limb perfusion, radiotherapy), regardless of the histological type of the neoplasm. It is a palliative type of treatment, and its objective is to obtain local control over cancerous lesions deteriorating the quality of life of the patients (infections, hemorrhages, limb function limitation). In selected cases, it is possible to obtain a long-term local control (e.g. in advanced, unresectable or qualifying to an extensive procedure on scalp and neck neoplasms and breast cancers with extensive dermis infiltration, reacting poorly to systemic treatment). Especially local breast cancer recurrence, frequently of large area or multiple with tissue infiltration, persisting despite systemic treatment, may be subject to electrochemotherapy. It especially applies to patients with disseminated cancer. In the paper, the authors are summarizing their experience in the application of that method among patients with breast cancer.
Elektrochemioterapia jest metodą terapii miejscowej zarezerwowaną dla przypadków nieoperacyjnych w zaawansowanych nowotworach zlokalizowanych powierzchownie w powłokach ciała. Może być stosowana zarówno w leczeniu pierwotnych nowotworów skóry (raki i czerniaki), jak i przerzutów innych nowotworów do skóry/tkanki podskórnej niekwalifikujących się do innej terapii (np. miejscowego wycięcia lub izolowanej perfuzji kończynowej, radioterapii), niezależnie od typu histologicznego nowotworu. Jest to z założenia leczenie paliatywne, a jego celem jest uzyskanie miejscowej kontroli nad zmianami nowotworowymi pogarszającymi jakość życia chorych (zakażenia, krwawienia, ograniczenie funkcji kończyn). W wybranych przypadkach możliwe jest uzyskanie długotrwałej kontroli miejscowej (np. w zaawansowanych, nieresekcyjnych lub kwalifikujących się do rozległego zabiegu okaleczającego nowotworach skóry głowy i szyi oraz rakach piersi z rozległym naciekiem skóry, słabo reagujących na leczenie systemowe). Zwłaszcza wznowy miejscowe raka piersi, nierzadko o dużej powierzchni lub liczne z naciekiem tkanek, utrzymujące się pomimo leczenia systemowego, mogą być poddane elektrochemioterapii. Dotyczy to szczególnie chorych z rozsianą chorobą nowotworową. W niniejszej pracy autorzy podsumowują własne doświadczenie w zastosowaniu tej metody u chorych na raka piersi.
