Proinflammatory Microenvironment in Adenocarcinoma Tissue of Colorectal Carcinoma.

Cancer-promoting proinflammatory microenvironment influences colorectal cancer (CRC) development. We examined the biomarkers of inflammation, intestinal differentiation, and DNA activity correlated with the clinical parameters to observe progression and prognosis in the adenocarcinoma subtype of CRC. Their immunohistology, immunoblotting, and RT-PCR analyses were performed in the adenocarcinoma and neighboring healthy tissues of 64 patients with CRC after routine colorectal surgery.

Non-Invasive 3D Breast Tumor Localization: A Viable Alternative to Invasive Tumor Marking.

We present a detailed description and the preliminary results of our original technique for non-invasive three-dimensional tumor localization in the breast, which was created as an alternative to standard invasive tumor marking before neoadjuvant systemic therapy (NAST), aiming to enable adequate surgery after complete tumor regression. A detailed description of the technique is provided in the main text. The technique's feasibility and precision were assessed in a single-arm, prospective study based on the histological parameters of the adequacy and rationality of the excision of completely regressed tumor beds.

DO THE GUIDELINES GUIDE THE BELGRADE EMERGENCY MEDICAL SERVICE PHYSICIANS THROUGH THE MANAGEMENT OF ACUTE ST-ELEVATION MYOCARDIAL INFARCTION?

The aim of the study was to assess whether current guidelines for diagnosis and treatment of acute ST-elevation myocardial infarction (STEMI) in daily clinical practice are adequately applied in the Belgrade Emergency Medical Service (EMS). A retrospective research included 2,982 STEMI patients who were cared for by EMS teams. Therapy consisting of morphine, oxygen, nitroglycerin and aspirin (MONA) was applied.

Changing the role of pCR in breast cancer treatment - an unjustifiable interpretation of a good prognostic factor as a "factor for a good prognosis".

Pathologic complete response (pCR) after neoadjuvant systemic therapy (NAST) of early breast cancer (EBC) has been recognized as a good prognostic factor in the treatment of breast cancer because of its significant correlation with long-term disease outcome. Based on this correlation, pCR has been accepted by health authorities (FDA, EMA) as a surrogate endpoint in clinical trials for accelerated drug approval. Moreover, in recent years, we have observed a tendency to treat pCR in routine clinical practice as a primary therapeutic target rather than just one of the pieces of information obtained from clinical trials.

Possible role of lead in breast cancer - a case-control study.

Numerous risk factors have been associated with breast cancer (BC), exposure to metalloestrogen, like lead, being such. Since lead involvement in BC is still equivocal, we focused on lead levels in three compartments of BC patients, blood, healthy, and malignant tissues. Also, as the cholesterol role in cancer development was recognized at the beginning of the twentieth century and led to involvement in lipid profile impairment, we further extend our research on lipid profile and enzymes responsible for maintaining lipid balance in BC patients.

Cadmium tissue level in women diagnosed with breast cancer - A case control study.

Breast cancer is at the forefront of female malignancy and the leading cause of cancer death among women. Gender, age, hormone therapy, smoking, exposure to endocrine disruptors and family history are significant breast cancer risk factors according to epidemiological data. Considering metalloestrogenic Cd property and a plethora of research work on hormone involvement in breast cancer the study aimed to determine Cd concentration in three compartments of breast cancer patients in relation to their blood hormone status.

Intraoperative ultrasound in breast cancer surgery-from localization of non-palpable tumors to objectively measurable excision.

Background: The utilization of intraoperative ultrasound (IOUS) in breast cancer surgery is a relatively new concept in surgical oncology. Over the last few decades, the field of breast cancer surgery has been striving for a more rational approach, directing its efforts towards removing the tumor entirely yet sparing tissue and structures not infiltrated by tumor cells. Further progress in objectivity and optimization of breast cancer excision is possible if we make the tumor and surrounding tissue visible and measurable in real time, during the course of the operation; IOUS seems to be the optimal solution to this complex requirement.

Lymph nodes behind the axillary neurovascular bundle: case report and cadaveric study of frequency and distribution.

Axillary clearance was undertaken in a 58-year-old male with massive lymph node enlargement caused by melanoma from an unknown primary site. We discovered a group of metastatic lymph nodes behind the axillary neurovascular bundle. This group of nodes (retro-axillary lymph nodes) could represent an extension of the subscapular group, or the seventh group of axillary lymphoid nodes.

Optimization of breast cancer excision by intraoperative ultrasound and marking needle - technique description and feasibility.

Background: We present a surgical technique and the preliminary results of breast cancer excision after insertion of a specially constructed marking needle into the tumor, controlled by intraoperative ultrasound. Resection margins were projected in six directions by ultrasound measurements, determined in relation to the needle, and resection was done in accordance with those measurements. The main objective was to obtain resection margins similar (equal) to those projected by intraoperative ultrasound (10 mm).
