Objective(s): This study sought to determine the diagnostic yield of SPECT/CT in localizing axillary sentinel lymph nodes (SLNs) in early breast cancer patients where planar scintigraphy (PS) was equivocal or negative.Methods: Prospective analysis of early stage breast cancer patients with nonpalpable axillary nodes undergoing SLN localization prior to nodal sampling for axillary staging. PS fi...

  Introduction: There is a consensus in the literature that sentinel lymph node biopsy is the standard procedure for axillary staging in early stage (I and II) breast cancer patients. Usually during lymphoscintigraphy, the location of the sentinel lymph node is marked on the skin by an indelible ink. In this study we evaluated this issue in our patients. Methods: 40 ...

AIM To state the limits of axillary lymphadenectomy in patients with metastatic melanoma. PATIENTS AND METHODS We performed a prospective study on patients submitted to axillary dissection for stage III melanoma. At surgery, the third-level nodes were separately dissected to be examined by the pathologist. RESULTS We analyzed 86 patients. In 93%, the third-level nodes were disease-free; non...

BACKGROUND The purpose of the present study was to retrospectively evaluate the effects of extracapsular extension (ECE) on the benefits of post-mastectomy radiation therapy (PMRT) for groups of patients with varying numbers of positive axillary nodes (1-3, 4-9 and ≥10 positive axillary nodes). METHODS A total of 1220 axillary node-positive patients who had received mastectomy were involved i...

Introduction. Patients with a positive sentinel lymph node biopsy may undergo delayed completion axillary dissection. Where intraoperative analysis is available, immediate completion axillary dissection can be performed. Alternatively, patients may undergo primary axillary dissection for breast cancer, historically or when preoperative assessment suggests axillary metastases. This study aims to...

BACKGROUND/AIM There are a lot of studies aiding to the opinion that the involvement degree of axilla lymph nodes grows depending on increase of breast tumor size, and its histological and nuclear grades. The aim of this study was to assess the risk of axillary lymph nodes involvement, as well as the relation between the tumor size, histological and nuclear grades in a group of female patients ...

OBJECTIVE This experiment aims to determine the diagnostic value of diffusion-weighted imaging (DWI) in the differentiation of axillary inflammatory lymph nodes from metastatic lymph nodes in rabbit models in comparison with conventional magnetic resonance imaging (MRI). MATERIALS AND METHODS Conventional MRI and DWI were performed at 4 weeks after successful inoculation into the forty female...

BACKGROUND Accurate detection and determination of axillary lymph node metastasis are crucial for the clinical management of patients with breast cancer. Noninvasive imaging methods including ultrasound (US), computed tomography (CT), or conventional magnetic resonance imaging (MRI) are not yet accurate enough. The purpose of this study was to investigate the value of in vivo T2* in differentia...

BACKGROUND Prone positioning for breast radiotherapy is preferable when the aim is a reduction of the dose to the ipsilateral lung or the heart in certain left-sided cases. MATERIALS AND METHODS In 100 breast cancer cases awaiting postoperative whole-breast radiotherapy, conformal radiotherapy plans were prospectively generated in both prone and supine positions. The axillary nodal region (le...
