Background: The spectrum of BRCA1 and BRCA2 mutations in Slavic countries is characterized by a high prevalence of founder alleles.

Methods: We analyzed a large data set of Russian breast cancer (BC) and ovarian cancer (OC) patients, who were subjected to founder mutation tests or full-length BRCA1 and BRCA2 analysis.

Results: The most commonly applied test, which included four founder mutations (BRCA1: 5382insC, 4153delA, 185delAG; BRCA2: 6174delT), identified BRCA1 or BRCA2 heterozygosity in 399/8533 (4.

Objective: To compare diagnostic accuracy of scintimammography (SMG) and digital mammography (DS) in the diagnosis of multicentric breast cancer.

Subjects And Methods: Three hundred and sixty seven women with histologically confirmed breast cancer were included in this analysis. All patients were candidates for conservative breast surgery and had cT1-3N0-1 stage of disease.

Background: This randomised, double-blind study compared PF-05280014 (a trastuzumab biosimilar) with reference trastuzumab (Herceptin®) sourced from the European Union (trastuzumab-EU), when each was given with paclitaxel as first-line treatment for HER2-positive metastatic breast cancer.

Methods: Between 4 April 2014 and 22 January 2016, 707 participants were randomised 1:1 to receive intravenous PF-05280014 plus paclitaxel (PF-05280014 group; n = 352) or trastuzumab-EU plus paclitaxel (trastuzumab-EU group; n = 355). PF-05280014 or trastuzumab-EU was administered weekly (first dose 4 mg/kg, subsequent doses 2 mg/kg), with the option to change to a 3-weekly regimen (6 mg/kg) from Week 33.

Aim: The aim of the present study was to determine the accuracy of single-photon emission computed tomography-computed tomography (SPECT-CT) with technetium-99m-sestamibi (Tc-MIBI) for detecting multiple (>2 nodes) axillary lymph node involvement in patients with breast cancer (BC).

Patients And Methods: A total of 184 women with BC were examined. Clinically, axillary lymph nodes were classified as N0 in all cases.

Objective: To determine diagnostic accuracy of SPECT, CT and SPECT-CT in axillary lymph node (LN) staging in breast cancer (BC).

Methods: Sixty consecutive patients with primary operable T1-3NxM0 BC were included in this study. All patients underwent SPECT-CT examination on Symbia-T16 scanner which consists of dual-head gamma camera combined with 16 slices diagnostic CT.
