Impact of analysis of the sentinel lymph node by one-step nucleic acid amplification (OSNA) compared to conventional histopathology on axillary and systemic treatment: data from the Dutch nationwide cohort of breast cancer patients.

Purpose: The outcome of the sentinel lymph node in breast cancer patients affects adjuvant treatment. Compared to conventional histopathology, analysis by one-step nucleic acid amplification (OSNA) harvests more micrometastasis, potentially inducing overtreatment. In this study we investigated the impact of OSNA analysis on adjuvant treatment, compared to histopathological analysis.

Influence of the sentinel node outcome analysed by one-step nucleic acid amplification on the risk for postmastectomy radiation therapy and the scheduling of immediate breast reconstruction.

Background: In patients with cT1-T3N0 breast cancer, postmastectomy radiation therapy (PMRT) is considered a contraindication for immediate breast reconstruction (IBR) due to a high risk of complications. The sentinel node biopsy (SNB) is an important determinant for PMRT. In this study, we evaluated the impact of SNB outcome on the planning of IBR after mastectomy.

Multifocality in ipsilateral breast tumor recurrence - A study in ablative specimens.

Background: The incidence and clinical significance of multifocality in ipsilateral breast tumor recurrence (IBTR) after breast-conserving therapy (BCT) are unclear. With growing interest in repeat BCT, this information has become of importance. This study aimed to gain insight in the incidence of multifocality in IBTR, to identify patient- and tumor-related predicting factors and to investigate the prognostic significance of multifocality.

Screening for distant metastases in patients with ipsilateral breast tumor recurrence: the impact of different imaging modalities on distant recurrence-free interval.

Purpose: In patients with ipsilateral breast tumor recurrence (IBTR), the detection of distant disease determines whether the intention of the treatment is curative or palliative. Therefore, adequate preoperative staging is imperative for optimal treatment planning. The aim of this study is to evaluate the impact of conventional imaging techniques, including chest X-ray and/or CT thorax-(abdomen), liver ultrasonography(US), and skeletal scintigraphy, on the distant recurrence-free interval (DRFI) in patients with IBTR, and to compare conventional imaging with F-FDG PET-CT or no imaging at all.

Low Risk of Development of a Regional Recurrence After an Unsuccessful Repeat Sentinel Lymph Node Biopsy in Patients with Ipsilateral Breast Tumor Recurrence.

Background: Unlike sentinel lymph node biopsy (SLNB) in the primary setting, the repeat SLNB (rSLNB) in patients with ipsilateral breast tumor recurrence (IBTR) is challenging, because it is difficult to visualize and/or harvest a sentinel lymph node in every patient. Regional treatments options and safety in terms of regional disease control after such an unsuccessful rSLNB remain unclear. This study assesses factors associated with the performance of axillary lymph node dissection (ALND) after unsuccessful rSLNB and evaluates the occurrence of regional recurrences.

Repeat breast-conserving therapy for ipsilateral breast cancer recurrence: A systematic review.

The standard of care for patients with an ipsilateral breast tumour recurrence (IBTR) after breast-conserving therapy (BCT) is a salvage mastectomy. However, there is growing interest in the feasibility of repeat BCT for these patients. This systematic review contains the latest insights on BCT options for patients with an IBTR after initial BCT.

The rationale for and long-term outcome of incomplete axillary staging in elderly women with primary breast cancer.

Background: The proportion of elderly women diagnosed with breast cancer is rising. Standard treatment, including axillary staging, is often not given to these patients. This study aimed to investigate reasons to omit any surgical axillary staging or to refrain from completion axillary lymph node dissection (cALND) after positive-sentinel lymph node biopsy (SLNB); so-called "incomplete staging".

The administration of adjuvant chemo(-immuno) therapy in the post ACOSOG-Z0011 era; a population based study.

Purpose: The ACOSOG-Z0011-study has resulted in a trend to a more conservative treatment of the axilla for selected sentinel-node-positive patients. However, axillary nodal involvement has always been an important factor for tumor staging and tailoring adjuvant chemotherapy plans. This study evaluates the impact of omitting completion axillary lymph node dissection (cALND) on the administration of adjuvant chemo (-immuno)therapy in Dutch clinical T1-2N0M0 (cT1-2N0M0) sentinel-node-positive breast cancer patients.

Risk of Regional Recurrence After Negative Repeat Sentinel Lymph Node Biopsy in Patients with Ipsilateral Breast Tumor Recurrence.

Background: Repeat sentinel lymph node biopsy (rSLNB) has increasingly been used in patients with ipsilateral breast tumor recurrence (IBTR). The safety in terms of regional disease control after this procedure remains unclear. This study evaluates occurrence of regional recurrence as first event in patients with IBTR and negative rSLNB, treated without additional lymph node dissection.

Repeat Sentinel Lymph Node Biopsy for Ipsilateral Breast Tumor Recurrence: A Systematic Review of the Results and Impact on Prognosis.

Background: During recent years, an increasing number of patients with ipsilateral breast tumor recurrence (IBTR) and previous axillary surgery have undergone repeat sentinel lymph node biopsy (rSLNB). The influence of axillary nodal status on prognosis for IBTR patients remains unclear. This study aimed to evaluate the technical success rate, follow-up assessment, and prognostic value of rSLNB for patients with IBTR.

Trends on Axillary Surgery in Nondistant Metastatic Breast Cancer Patients Treated Between 2011 and 2015: A Dutch Population-based Study in the ACOSOG-Z0011 and AMAROS Era.

Objectives: To evaluate patterns of care in axillary surgery for Dutch clinical T1-4N0M0 (cT1-4N0M0) breast cancer patients and to assess the effect of the American College for Surgeons Oncology Group (ACOSOG)-Z0011 and After Mapping of the Axilla: Radiotherapy Or Surgery (AMAROS) trial on axillary surgery patterns in Dutch cT1-2N0M0 sentinel node positive breast cancer patients.

Background: Since publication of the ACOSOG-Z0011 and AMAROS trial, omitting a completion axillary lymph node dissection (cALND) in sentinel node positive breast cancer patients is proposed in selected patients.

Methods: Data were obtained from the nationwide Nationaal Borstkanker Overleg Nederland breast cancer audit.

Complications of Lower Body Lift Surgery in Postbariatric Patients.

Unlabelled: There is an exponential rise of patients with massive weight loss because of bariatric surgery or lifestyle changes. The result is an increase of patients with folds of redundant skin that may cause physical and psychological problems. The lower body lift is a procedure to correct deformities in the abdomen, mons, flanks, lateral thighs, and buttocks.
