Neurturin gene IVSI-663 polymorphism but not RET variants is associated with increased risk for breast cancer.

Background: Gene polymorphisms of rearranged during transfection (RET) and its ligand neurturin (NRTN) are one of the focus of studies in the investigation of cancer pathogenesis, invasion, and metastasis. In this study, we aimed to examine the possible risk of breast cancer between RET G691S, L769L, S904S, and NRTN IVSI-663 polymorphisms and to evaluate serum NRTN, brain-derived neurotrophic factor (BDNF), matrix metalloproteinase (MMP)-2, MMP-9, and focal adhesion kinase (FAK) levels.

Methods: The study consists of 110 breast cancer patients and 110 controls.

Relationship Between Metabolic Activity, Cellularity, Histopathological Features of Primary Tumors and Distant Metastatic Potential in Breast Cancer.

Objectives: The aim of this study was to evaluate the relationship between the types of distant metastatic spread, histopathological features, and imaging features of primary tumor on positron emission tomography/magnetic resonance imaging (PET/MRI) for primary staging in newly diagnosed breast invasive ductal carcinoma (IDC) patients.

Methods: Data from 289 female patients were retrospectively evaluated. Maximum standardized uptake value, metabolic tumor volume (MTV), total lesion glycolysis (TLG), and minimum apparent diffusion coefficient (ADC) values of primary tumors were obtained from PET/MRI.

Does Venipuncture Increase Lymphedema by Triggering Inflammation or Infection? An Experimental Rabbit Ear Lymphedema Model Study.

Recent guidelines recommend avoiding venipuncture to prevent lymphedema for breast cancer patients. This study investigated whether single or multiple sterile venipuncture procedures develop a systemic inflammation or infection and increase lymphedema in the rabbit ear lymphedema model. Eighteen New Zealand white female rabbits were included.

Is There Any Association Between Mammographic Features of Microcalcifications and Breast Cancer Subtypes in Ductal Carcinoma In Situ?

Rationale And Objectives: To analyze the association between mammographic features of microcalcifications and histopathological prognostic factors based on estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2/neu) in ductal carcinoma in situ (DCIS).

Materials And Methods: We retrospectively determined 66 patients with microcalcification-associated pure DCIS. Distribution and morphological features of the microcalcifications were described using Breast Imaging Reporting and Data System lexicon.

An Approach to Macroscopic Central Lymph Nodes Detected during Surgery in Patients with Thyroid Micropapillary Carcinoma: Should We Resort to Dissection?

. High-resolution ultrasonography and the ability to perform fine-needle aspiration biopsy even for nodules smaller than three millimeters have considerably increased the detection rate of thyroid micropapillary carcinoma (TMPC). Despite favorable prognosis, the prevalence of cervical lymph node metastases in patients with TMPC is approximately 30%.
