Breast Cancer in Young Women: Status Quo and Advanced Disease Management by a Predictive, Preventive, and Personalized Approach.

Why does healthcare of breast cancer (BC) patients, especially in a young population, matter and why are innovative strategies by predictive, preventive, and personalized medicine (PPPM) strongly recommended to replace current reactive medical approach in BC management? Permanent increase in annual numbers of new BC cases with particularly quick growth of premenopausal BC patients, an absence of clearly described risk factors for those patients, as well as established screening tools and programs represent important reasons to focus on BC in young women. Moreover, "young" BC cases are frequently "asymptomatic", difficult to diagnose, and to treat effectively on time. The objective of this article is to update the knowledge on BC in young females, its unique molecular signature, newest concepts in diagnostics and therapy, and to highlight the concepts of predictive, preventive, and personalized medicine with a well-acknowledged potential to advance the overall disease management.

Effect of Postoperative Radiotherapy for Brain Metastases: An Analysis.

Introduction: Brain metastases (BM) have a very poor prognosis, creating a demand for effective local therapies, such as radiotherapy (RT) and neurosurgery, the combination of which is debatable. The aim of the present study was to investigate prognostic factors and to develop treatment recommendations for patients with BM.

Material And Methods: A total of 84 patients treated between May 2011 and July 2016 were analyzed in a single-institution retrospective study.

Patients with hepatic breast cancer metastases demonstrate highly specific profiles of matrix metalloproteinases MMP-2 and MMP-9 after SIRT treatment as compared to other primary and secondary liver tumours.

Background: Patients with primary and metastatic liver malignancies represent a highly heterogeneous patient pool characterised by some of the shortest life expectancies amongst oncology patients. Investigation and better understanding of liver malignancies is an emerging field which requires high-quality multidisciplinary research and collaboration.

Methods: A study of 158 patients with primary hepatic carcinomas and secondary liver metastases, altogether 15 cancer types of different origin, who underwent selective internal radiation therapy (SIRT) with Yttrium(90) or transarterial chemoembolisation, was undertaken in an effort to detect distinguishing features with respect to activity profiles of both blood matrix metalloproteinase (MMP-2 and MMP-9).

Risk assessment, disease prevention and personalised treatments in breast cancer: is clinically qualified integrative approach in the horizon?

Breast cancer is a multifactorial disease. A spectrum of internal and external factors contributes to the disease promotion such as a genetic predisposition, chronic inflammatory processes, exposure to toxic compounds, abundant stress factors, a shift-worker job, etc. The cumulative effects lead to high incidence of breast cancer in populations worldwide.

Irradiated breast cancer patients demonstrate subgroup-specific regularities in protein expression patterns of circulating leukocytes.

Background: Breast cancer is one of the most frequent types of cancer with fatal outcome worldwide. The use of breast conserving lumpectomy followed by radiation therapy is common and has been shown to be a strategy competitive to mastectomy in preventing mortality caused by breast cancer. However, breast irradiation, particularly applied after pre-irradiation chemotherapy, frequently leads to serious short- and long-term side-effects, the prediction of which is highly desirable in terms of individual therapy planning.

Up-regulation of vimentin expression in low-density malignant glioma cells as immediate and late effects under irradiation and temozolomide treatment.

Nervous system tumors are one of the leading causes of cancer related death. Specific mechanisms facilitating the invasive behavior of gliomas remain obscure. Advanced simulation models of the in vivo response to therapy conditions should potentially improve malignant glioma treatment.

Pro-invasive gene regulating effect of irradiation and combined temozolomide-radiation treatment on surviving human malignant glioma cells.

The current chemotherapeutic treatment of glioblastoma patients has minor success. Little is known about the molecular and cellular mechanisms of the resistance of gliomas towards current therapies. This study investigated both suppressive cellular effects and regulation of extracellular matrix remodeling proteins with pro-invasive activity in surviving human glioblastoma cells under clinically relevant treatments.

Is current therapy of malignant gliomas beneficial for patients? Proteomics evidence of shifts in glioma cells expression patterns under clinically relevant treatment conditions.

The most common human brain tumours - gliomas - have poor prognosis with and without treatment. The current therapy conditions act sub-lethally and cannot effectively suppress the proliferation of glioma cells. Here we show differential protein expression patterns in surviving human malignant U87-MG glioma cells under clinically relevant chemo/radiotherapy.

Activation of genes inducing cell-cycle arrest and of increased DNA repair in the hearts of rats with early streptozotocin-induced diabetes mellitus.

Background: Oxidative stress was proposed as a critical factor in diabetic complications. The etiology of cell degeneration in diabetes mellitus (DM)-induced cardiomyopathy is unclear. The transition between apoptotic degeneration and cell proliferation under stress conditions is regulated at cell-cycle checkpoints.

[Volumetric changes of the breast during radiotherapy. Is a replanning necessary for the electron boost?].

Background And Purpose: Radiotherapy can induce tissue reactions with an edema leading to increased breast volume. The aim of the present study was to quantify this increase and analyze its effect on the electron boost technique.

Patients And Methods: 140 patients with breast cancer treated with breast-conserving surgery underwent CT planning before, during and/or after radiotherapy in order to evaluate breast volume changes due to radiotherapy.
