Over the last decade, regularized regression methods have offered alternatives for performing multi-marker analysis and feature selection in a whole genome context. The process of defining a list of genes that will characterize an expression profile remains unclear. It currently relies upon advanced statistics and can use an agnostic point of view or include some a priori knowledge, but overfitting remains a problem. This paper introduces a methodology to deal with the variable selection and model estimation problems in the high-dimensional set-up, which can be particularly useful in the whole genome context. Results are validated using simulated data and a real dataset from a triple-negative breast cancer study.

Breast cancer (BC) is one of the leading cause of death in developed Countries and every year more than a million new cases are diagnosed worldwide. In Italy the prevalence of BC was estimated to be 1,070 per 100,000 at 31 December 1992. Nevertheless, despite the increase in incidence, mortality rate for BC are decreased in the last decades probably due to several factors such as implementation of screening programs, early diagnosis and new adjuvant therapies. Important types of adjuvant chemotherapy include anthracyclines and taxanes and these treatments continue to be evaluated to determine optimal combinations and dosing regimens. The efficacy of paclitaxel and docetaxel in adjuvant setting for the treatment of early BC has been assessed in different trials where the two taxanes showed a significant increase in both Disease Free Survival (DFS) and Overall Survival (OS) in comparison with nontaxane therapy. In particular results from one of the last studies comparing paclitaxel and docetaxel show equivalent efficacy for both drugs. At the light of the recent findings, the objective of this work is to perform a cost minimization analysis of paclitaxel vs docetaxel in the adjuvant setting for treatment of early BC in Italy. The analysis was conducted from the National Health Service’s point of view, assuming equivalent efficacy in terms of DFS and OS for both taxanes. Costs were evaluated on the basis of therapeutic schemes used in the analyzed trials. Results show that paclitaxel, administered every 3 weeks for 4 cycles after doxorubicin and cyclophosphamide, represents the less costly therapy. This is a conservative costs estimate based on data from literature that does not take into account possible additional costs associated to the treatment of febrile neutropenia (FN) as adverse event related to chemotherapy. Since, on the basis of scientific literature data, FN seems to be more related with docetaxel than with paclitaxel administration, it is likely that in clinical practice the Growth–Colony Stimulating Factor is often prescribed as a preventive therapy when Docetaxel is administred, giving rise to treatment costs.

An obvious questioning of the doctor-patient relationship leads us to conduct a research on the point of view of patients who have had to follow a breast cancer treatment pathway. We want to know to what extent the notions of distance/proximity make it possible to explain the doctors-patients relationships, and on what realities it is based. It appears that the answer is complex, multifaceted, and rather poses the question of the dimensions of the relationship alongside the medical protocol.

Introduction. While the “no tumor on ink” approach is generally accepted for breast-conserving surgery (BCS) in patient with breast cancer, it remains unclear whether it is oncologically safe for BCS after neoadjuvant chemotherapy therapy (NACT). The aim of the study is to investigate the optimal width of the resection edges in BCS after NALT and the influence on disease-free and overall survival in patients with breast cancer. Materials and methods. Retrospectively, the medical documentation of 76 patients with breast cancer, who were performed BCS after NACT, was studied. The distribution by stage of breast cancer was as follows: I St. -5 patients, II St. - 55, III St. - 16 (excluded IIIB St.). Invasive cancer of non-specific type was diagnosed in 81.6% of cases, in 6.5% - lobular cancer, in 1.3% - combined breast cancer. Radical breast resections in the classic version were performed in 28 cases, and oncoplastic resections in various modifications were performed in 48 Cases. Results. We present the retrospective data of 76 patients with breast cancer who underwent OSA after NALT in the Department of breast and skin cancer OF the Moscow Institute of medical research. P. A. Herzen. The results of our study demonstrated the oncological safety of OSO with respect to new sizes of tumor nodes after NALT followed by remote radiotherapy. The method of “absence of tumor cells” at the edges of resection demonstrated a high percentage of 1, 3, 5-year relapse - free and overall survival, the frequency of relapse was 2.6%. There was no statistically significant difference in 1, 3, 5-year relapse-free and overall survival when the width of the resection edges was more or less than 1 mm. Conclusion. The results of numerous studies have demonstrated that the breast- conserving surgery is the safe method of surgical treatment from an oncological point of view and is an alternative for radical mastectomies for patients with the breast cancer after neoadjuvant chemotherapy.

The cathepsin D concentration in 18 women with benign breast pathology has a cut-off value of 43 pmol/mg of protein. High values have been detected in two cases of chronic mastitis. These high values of cathepsin D were found in a study of 62 patients suffering from breast cancer and are independent of the hormone dependent state of the tumour. The cathepsin D concentration may have a prognostic function in breast cancer determination, as high concentrations are found in combination with other prognostic factors such as clinical stage, size of the tumour, state of the axillary lymph nodes and in the histological differentiation grade, where from a statistical point of view, the combination is important.
