PURPOSE: To evaluate the practice patterns for the use of regional nodal irradiation (RNI) in treatment of elderly women with low volume node-positive breast cancer in the setting of breast conservation surgery (BCS). METHODS: Women aged 70-89 diagnosed with unilateral, pathologic T1-2N1M0 breast cancer from 2004 to 2013, who underwent BCS and received radiotherapy were identified from the National Cancer Database. In 2011, two major trials were presented that helped define indications for RNI...

INTRODUCTION: The conservative surgery is more and more indicated for breast cancer. However, we still fear local recurrence which is mostly due to residual tumors?. Several techniques have been used to minimize theses residual tumors; one of them is the systematic circumferential tumor cavity shaving (SCTCS). METHODS: We sampled 75 female patients who had conservative surgery with positive shaved margins in the anatomopathology examination and to whom a complementary treatment with mastectomy have been decided...

The survival of patients with breast cancer has improved considerably thanks to adjuvant radiotherapy and systemic treatments. Due to the potential adverse events associated with these treatments, a de-escalation effort was undertaken concerning surgery and more recently the adjuvant treatments. Conservative breast surgery and the avoidance of axillary dissection were possible for the majority of the patients without detrimental effect on survival. New radiotherapy techniques and the consideration of cancer biology allowed to better protect the peripheral organs and even to avoid treatment in certain low-risk patients...

INTRODUCTION: Tumor bed boost improves local control and is an important part of breast-conserving therapy. Data on the use of a hypofractioned tumor bed boost are needed. We performed a retrospective analysis of patients treated with hypofractionated whole breast irradiation (WBI) and hypofractionated boost to examine acute and delayed outcomes. MATERIALS AND METHODS: We examined the records of patients treated with hypofractionated WBI and tumor bed boost after lumpectomy for Stage 0 to II breast cancer...

It is well recognized that the incidence of breast cancer increases significantly with age. Despite this, older people remain under-represented in many clinical trials and their management relies on extrapolation of data from younger patients. Providing an aggressive intervention can be challenging, particularly in less fit older patients where a conservative approach is commonly perceived to be more appropriate. The optimal management of this population is unknown and treatment decision should be personalized...

Male breast cancer (MBC) comprises <1% of all breast cancers in the United States. MBC is typically treated with total mastectomy while the majority of female breast cancer is treated with breast conservation therapy combined with various forms of radiation. One method that has developed over the last two decades is the use of intraoperative radiation therapy (IORT) as a type of accelerated partial breast irradiation to direct the treatment field to the tumor bed. Since overall prognosis and systemic therapy recommendations for MBC are similar to breast cancer in women, we describe the first case of MBC treated with BCS and IORT...

BACKGROUND: The Dutch guidelines advise to start radiation therapy (RT) within 5 weeks following breast-conserving surgery (BCS). However, much controversy exists regarding timing of RT. This study investigated its effect on 10-year disease-free survival (DFS) in a Dutch population-based cohort. METHODS: All women diagnosed with primary invasive stage I-IIIA breast cancer in 2003 treated with BCS+RT were included. Two populations were studied. Population 1 excluded patients receiving chemotherapy before RT...

Despite advances in diagnosis and new treatments such as targeted therapies, breast cancer (BC) is still the most prevalent tumor in women worldwide and the leading cause of death. The principal obstacle for successful BC treatment is the acquired or de novo resistance of the tumors to the systemic therapy (chemotherapy, endocrine, and targeted therapies) that patients receive. In the era of personalized treatment, several studies have focused on the search for biomarkers capable of predicting the response to this therapy; microRNAs (miRNAs) stand out among these markers due to their broad spectrum or potential clinical applications...

BACKGROUND: The benefit of neoadjuvant chemotherapy (NAC) in patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancers and in invasive lobular carcinoma (ILC) is uncertain due to the low rates of pathologic complete response (pCR). OBJECTIVE: The aim of this study was to determine if pathologic features can identify subsets likely to benefit from NAC. METHODS: Patients with stage I-III ER+, HER2- breast cancer receiving NAC were retrospectively reviewed...

Conservative breast cancer surgery followed by radiation therapy is the standard treatment for this type of cancer. Numerous studies demonstrate that 90% of local recurrences after traditional surgery occur in the same quadrant as the primary cancer. The published data suggest that the wound healing process after surgery alters the area surrounding the original tumor and the modified microenvironment is more favorable for the tumor to recur. The majority of metastases within scar initiated much research, and the consequences of these studies led to clinical trials aimed at assessing whether localized radiotherapy, such as intraoperative radiotherapy (IORT), would be more effective in inhibiting formation of local recurrence than the standard postoperative whole breast radiotherapy...

For the second time, the St. Gallen Consensus Conference on early breast cancer treatment standards took place in Vienna, Austria, where it will remain for the foreseeable future (next date: March 20-23, 2019). With the probably most prominent line-up of global breast cancer experts and more than 3,000 participants from over 100 countries, the 2017 St. Gallen/Vienna conference again was a huge success. A generation change took place with respect to the Conference Co-Chairpersons. Traditionally, the experts from all continents reviewed publications from the past 2 years, and discussed whether new diagnostic or therapeutic means were ready for routine everyday practice...

BACKGROUND: Neo-adjuvant chemotherapy (NAC) can facilitate breast conservation, allows in vivo testing of chemotherapy sensitivity and provides a route to accelerated approval of new therapies. For HER2 positive breast cancer, the anti-HER2 monoclonal antibody, trastuzumab, is a standard component of neo-adjuvant therapy for HER2 positive breast cancer. Pertuzumab is an anti-HER2 monoclonal antibody with a distinct binding site to trastuzumab, which prevents HER2 receptor dimerisation...

BACKGROUND: A standardized classification system for breast surgery that incorporates oncoplastic techniques is needed. We classified the surgical techniques for breast cancer treatment into five groups according to the extent of surgery and reconstructive methods, i.e. conventional breast-conserving surgery, partial mastectomy with volume displacement, partial mastectomy with volume replacement, simple mastectomy and total mastectomy with immediate reconstruction. We then evaluated the oncological outcomes for each of the five groups...

For years, lobular carcinoma In Situ (LCIS) has been considered a high-risk marker for developing breast cancer. It is well known that ductal carcinoma In Situ is a precursor for the development of invasive ductal carcinoma, and ductal carcinoma In Situ is reported to be present in invasive ductal carcinoma in at least 40 per cent of cases. A similar relationship between LCIS and invasive lobular carcinoma (ILC) remains in question. This study evaluates the incidence of synchronous LCIS and ILC at our institution...

BACKGROUND: Fat grafting has been widely indicated for postmastectomy and postlumpectomy breast reconstruction. The literature emphasizes the clinical efficacy of fat grafting, but experimental studies raise important questions about the recurrence risk because of the stimulation of remaining cancer cells by progenitor or adult adipocytes. Because breast conservative treatment provides a higher risk of residual cancer cells in the breast tissue compared with mastectomy, the authors set up a matched case-control study of fat grafting versus no fat grafting after breast conservative treatment...
