Omitting Axillary Dissection in Triple-Negative and HER2-Overexpressed Breast Cancers With Positive Sentinel Lymph Nodes During Upfront Surgery: SENATURK-OTHELLO Study.

Purpose: Randomized trials including ACOSOG Z0011 and SENOMAC mostly included patients with hormone receptor-positive breast cancer, but a limited number of patients with aggressive tumor biology. Therefore, we assessed the oncological safety of omitting axillary dissection in patients with SLN-positive HER2-positive or triple-negative breast cancer at upfront surgery.

Materials And Methods: This retrospective cohort study included patients with clinically node-negative HER2-positive and triple-negative breast cancer who had sentinel lymph node biopsy (SLNB) alone with pN+ disease.

De-Escalation of Nodal Surgery in Clinically Node-Positive Breast Cancer.

Importance: Increasing evidence supports the oncologic safety of de-escalating axillary surgery for patients with breast cancer after neoadjuvant chemotherapy (NAC).

Objective: To evaluate the oncologic outcomes of de-escalating axillary surgery among patients with clinically node (cN)-positive breast cancer and patients whose disease became cN negative after NAC (ycN negative).

Design, Setting, And Participants: In the NEOSENTITURK MF-1803 prospective cohort registry trial, patients from 37 centers with cT1-4N1-3M0 disease treated with sentinel lymph node biopsy (SLNB) or targeted axillary dissection (TAD) alone or with ypN-negative or ypN-positive disease after NAC were recruited between February 15, 2019, and January 1, 2023, and evaluated.

ASO Author Reflections: Nodal Recurrence Is Rare in Patients with cN+/ycN0 Breast Cancer after Neoadjuvant Chemotherapy Regardless of the Extent of Axillary Surgery or Nodal Pathology in the NEOSENTITURK-Trials MF18-02/18-03 Provided Regional Nodal Irradiation Is Administered.

The combined analysis of the retrospective multicentre and prospective multicenter cohort registry trial NEOSENTITURK MF18-02/18-03 (NCT04250129) investigated the outcomes and factors associated with recurrence in patients with cT1-4N1-3M0 who underwent a succesful sentinel lymph node biopsy or targeted axillary dissection (n = 1470), with or without axillary lymph node dissection (n = 937) after neoadjuvant chemotherapy. The present large registry data suggest that axillary recurrences (AR) can be detected at exceedingly low rates (< 0.5%) within 3 years after surgery.

Breast Cancer Recurrence in Initially Clinically Node-Positive Patients Undergoing Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy in the NEOSENTITURK-Trials MF18-02/18-03.

Background: This study aims to identify factors predicting recurrence and unfavorable prognosis in cN+ patients who have undergone sentinel lymph node biopsy (SLNB) following neoadjuvant chemotherapy (NAC).

A New Convenient Incision Model of the Nipple-Sparing Mastectomy: Lateralized Parabolic Multiplanar Incision.

Background: In this study, a lateralized parabolic multiplanar incision was defined. It was aimed to reduce necrosis in the nipple-areola complex (NAC) and, in the long run, to prevent the scar from pulling the areola laterally by maintaining healthy skin tissue between the scar and the areola and preserving the natural round appearance of the areola. Moreover, we purposed the scar not to be visible from the anterior view.

Local steroid injection in severe idiopathic granulomatous mastitis as a new first-line treatment modality with promising therapeutic efficacy.

Background: Intralesional steroid injection has recently evolved as a novel treatment modality for localized idiopathic granulomatous mastitis (= IGM). We aimed to explore the therapeutic efficacy of local steroid injections (LSI) in patients with severe IGM.

Methods: Fifty-one patients diagnosed with severe IGM were included in the study and treated with either local steroid injection (LSI) alone ( = 25) or combined LSI with systemic oral steroid treatment (OST) ( = 26).

Materials And Methods: We conducted a retrospective study, extracting data from medical records of 64 patients diagnosed with breast cancer. A retrospective analysis was performed on all patients who had Oncotype Dx Recurrence Scores across five medical centers between 2017 and 2022.

Sentinel lymph node biopsy after nipple-sparing mastectomy in early postoperative period: Is it feasible?

Background: Axillary lymph node status is one of the most important prognostic factors for breast cancer. Sentinel lymph node biopsy (SLNB) after mastectomy is highly controversial. There is not enough data about SLNB in the early period after nipple-sparing mastectomy (NSM).

Survival results according to Oncotype Dx recurrence score in patients with hormone receptor positive HER-2 negative early-stage breast cancer: first multicenter Oncotype Dx recurrence score survival data of Turkey.

Background: The Oncotype Dx recurrence score (ODx-RS) guides the adjuvant chemotherapy decision-making process for patients with early-stage hormone receptor-positive, HER-2 receptor-negative breast cancer. This study aimed to evaluate survival and its correlation with ODx-RS in pT1-2, N0-N1mic patients treated with adjuvant therapy based on tumor board decisions.

Patients And Methods: Estrogen-positive HER-2 negative early-stage breast cancer patients (pT1-2 N0, N1mic) with known ODx-RS, operated on between 2010 and 2014, were included in this study.

Implant selection in natural and stable direct-to-implant reconstruction with ten steps at nipple-sparing mastectomy.

Direct-to-implant reconstruction is one of the breast repair techniques after mastectomy. Implant selection is critical in the short- and long-term success of direct-to-implant reconstruction after nipple-sparing mastectomy. In this study we developed a 10-step algorithm that we use before and during surgery.

Methods: This descriptive, prospective study was conducted in 2019-2020 with the participation of 531 women who survived breast cancer and were under follow-up at the Senology Institute of a hospital in Istanbul.

Comparison of mammography and ultrasound findings in the follow-up of patients with breast cancer treated with segmental mastectomy followed by intraoperative electron radiotherapy versus external whole breast radiotherapy.

Purpose: This study aims to describe imaging findings in patients treated with intraoperative electron radiotherapy and compare them with those detected in patients treated with external whole breast radiotherapy (WBRT).

Methods: The study population consisted of 25 patients who received intraoperative radiotherapy [IORT (21 Gy)] as single-dose radiotherapy and a control group of 25 patients who received WBRT at the same institution. Mammography and ultrasound (US) findings were divided into three groups: minor, intermediate, and advanced.

Transmesocolic approach in laparoscopic complete mesocolic excision for right sided colon cancers.

Introduction: A mesocolic plane, central vascular ligation (CVL) and proper proximal-distal margins are the essential components of complete mesocolic excision (CME). In the transmesocolic approach, we identify the middle colic vessels and enter the lesser sac through the mesocolon for ascending colon and caecum tumors.

Aim: To investigate the feasibility and identify the technical details of this technique.

Comparison of PET-CT and MRI for evaluation of axillary lymph nodes in early breast cancer patients.

Background: Evaluation of axillary lymph node in women with breast cancer is very important as it can change the initial treatment decision. None of the noninvasive methods used for assessment of axilla is accurate as sentinel lymph node biopsy (SLNB) yet. This study compared the diagnostic performance of 18-fluorodeoxyglucose positron emission tomography/ computed tomography (PET-CT) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) in preoperative axillary evaluation of women diagnosed with early breast cancer (EBC).

Favorable locoregional control in clinically node-negative hormone-receptor positive breast cancer with low 21-gene recurrence scores: a single-institution study with 10-year follow-up.

Background: Recent studies have shown a lower likelihood of locoregional recurrences in patients with a low 21-gene recurrence score (RS). In this single-institution study, we investigated whether there are any associations between different cutoff values of 21-gene RS, histopathological factors, and outcome in patients with long-term follow-up.

Methods: The study included 61 patients who had early-stage (I-II) clinically node-negative hormone receptor-positive and HER2-negative breast cancer and were tested with the 21-gene RS assay between February 2010 and February 2013.

Do prognosis and clinicopathological features differ in young early-stage breast cancer?

Background: Breast cancer is the most frequently detected cancer and the leading cause of cancer-related death in women. Although it is mostly seen in older patients, breast cancer affects women aged 24 to >70 years, with poorer prognosis in young patients. Young age remains a controversial topic in the literature.

Impact of preoperative PET/CT for axillary staging in patients with early breast cancer.

Background: Preoperative evaluation of axillary lymph node status is very important for the choice of primary treatment in breast cancer. This study assessed predictive properties of positron emission tomography-computerized tomography for axillary lymph node metastasis.

Methods: Patients who were operated between 2014-2019 for early breast cancer and who had preoperative positron emission tomography-computerized tomography images were included.

Has the COVID-19 Pandemic Affected Breast Cancer Stage and Surgical Volume?

Background: This study investigates the effects of COVID-19 on the breast cancer stage and the volume of breast cancer surgery in a specialized breast institute.

Methods: Data of 332 patients who were diagnosed and treated for breast cancer between December 2019 and November 2020 were evaluated retrospectively according to periods of pandemic.

Results: A significant decrease in the number of operations, especially upfront surgeries rather than surgeries after neoadjuvant chemotherapy, was detected in the early period of the COVID-19 pandemic.

Robotic nipple sparing mastectomy through a single incision: Advantages of starting with posterior dissection.

Objectives: Loss of breast, which is an important body marking of women, causes a huge decrease in quality of life (QoL) after treatment. In order to overcome this morbidity and increase QoL, nipple sparing mastectomy (NSM) has been developed. Even though the demand for better cosmetic results has yielded endoscopic nipple sparing mastectomy, limitations like unsuitable optical window and limited manual control of rigid-tip instruments, and struggling to keep dissection space have led robotic nipple sparing mastectomy (rNSM) to be developed.
