During the recent years an increase of mastectomy rates in early breast cancer patients has been observed. Nevertheless, several large population-based studies reported a possible improved outcome after breast conserving therapy compared to radical surgery, after all the adjustments. We hereby summarize our opinion on this topic suggesting that these robust and consistent data might challenge the statement that breast conserving therapy is merely not inferior to radical surgery.

BACKGROUND: Breast cancer tissue is sensitive to hypofractionation. This is an analysis of patients treated with hypofractionated protocols since 2009, at our tertiary cancer center. METHODS: Details of breast cancer patients treated with adjuvant hypofractionated external beam radiation therapy (EBRT) from January 2009 to December 2014 were retrieved and analyzed. RESULTS: One thousand seven hundred and eighty patients received adjuvant EBRT during this period...

Approaches to achieve site-specific and targeted delivery that provide an effective solution to reduce negative, off target side-effects are urgently needed for cancer therapy. Here, we utilized a Trojan horse-like strategy to carry photosensitizer Chlorin e6 conjugated porous silicon multistage nanovectors with tumor homing mesenchymal stem cells for targeted photodynamic therapy and diagnosis. The inherent versatility of multistage nanovectors permitted the conjugation of photosensitizers to enable precise cell death induction (60%) upon photodynamic therapy, while simultaneously retaining the loading capacity to load various payloads, such as antitumor drugs and diagnostic nanoparticles...

PURPOSE: Results from four major hypofractionated whole-breast radiotherapy (HF-WBRT) trials have demonstrated equivalence in select patients with early-stage breast cancer when compared with conventionally fractionated WBRT (CF-WBRT). Because relatively little data were available on patients receiving neoadjuvant or adjuvant chemotherapy, consensus guidelines published in 2011 did not endorse the use of HF-WBRT in this population. Our goal is to evaluate trends in utilization of HF-WBRT in patients receiving chemotherapy...

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...

PURPOSE: The potential of diffusion weighted imaging (DWI) in assessing pathologic response and surgical margins in locally advanced breast cancer patients (n=38) undergoing neoadjuvant chemotherapy was investigated. METHODS: DWI was performed at pre-therapy (Tp0), after I (Tp1) and III (Tp3) NACT at 1.5T. Apparent diffusion coefficient (ADC) of whole tumor (ADCWT), solid tumor (ADCST), intra-tumoral necrosis (ADCNec) was determined. Further, ADC of 6 consecutive shells (5mm thickness each) including tumor margin to outside tumor margins (OM1 to OM5) was calculated and the data analyzed to define surgical margins...

A 61-year-old woman was referred to our hospital because of a right breast mass. A 19 mm hard mass was palpable in the A area of the right breast. A contrast-enhanced MRI showed rim enhancement at the peripheral region of the tumor, which was thought to represent the carcinoma component mainly at the periphery and the matrix component inside the tumor. A low density mass with rim enhancement at the peripheral region was observed in a contrast-enhanced CT, the same as in the MRI. Neither axillary lymph node metastasis nor distant metastasis was observed...

The different molecular subtypes of breast cancer are associated with distinct outcomes. We assessed the efficacy of breast conservation therapy (BCT) followed by radiotherapy for patients with different breast cancer subtypes. We searched the MEDLINE, EMBASE, and Cochrane Library databases to identify studies published prior to April 30, 2016 that assessed the efficacy of BCT followed by radiotherapy in breast cancer patients with different molecular subtypes. A meta-analysis of seven studies that included 3,798 luminal A, 770 luminal B, 344 human epidermal growth factor receptor 2 (Her-2), and 767 triple-negative breast cancer (TNBC) patients was performed...

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...

OBJECTIVES: Ubiquitin specific protease 32 (USP32) is a highly conserved but uncharacterized gene, which has been reported to be associated with growth of breast cancer cells. However, the role of USP32 in human small cell lung cancer (SCLC) has not been uncovered. The aim of this study was to investigate and evaluate the clinical significance of USP32 in patients with SCLC. MATERIALS AND METHODS: Expression of USP32 was firstly investigated using public online data sets and then determined in SCLC tissues and cell lines using quantitative real-time PCR, Western blotting and immunohistochemical staining...

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...
