BACKGROUND: The use of post-mastectomy radiotherapy (PMRT) following immediate breast reconstruction has increased recently, and its safety is becoming a major concern. We aimed to evaluate the complication rates of PMRT to immediate tissue-expander/permanent implant (TE/PI)-based reconstructions for breast cancer and its association with radiotherapy timing (irradiation to TE or PI). METHODS: We retrospectively reviewed the cases of breast cancer patients who underwent mastectomy, immediate TE/PI reconstruction, and PMRT between January 2003 and December 2014...

BACKGROUND: The side effects of radiotherapy (RT) and the occurrence of comorbidity often result in appetite loss in patients, which leads to serious nutritional problems, significantly affecting the patients' treatment results and disease prognosis. OBJECTIVES: We aimed to investigate changes in the body composition of patients with cancer from the time they received RT to 3 months after completion of RT. DESIGN: A total of 101 cancer patients who received RT, which included head or neck cancer, chest or breast cancer, and abdominal or pelvic cancer patients...

Breast cancer remains the second most common disease worldwide. Radiotherapy, alone or in combination with chemotherapy, is widely used after surgery as a treatment for cancer with proven therapeutic efficacy manifested by reduced incidence of loco-regional and distant recurrences. However, clinical evidence indicates that relapses occurring after radiotherapy are associated with increased metastatic potential and poor prognosis in the breast. Among the anticarcinogenic and antiproliferative agents, curcumin is a well-known major dietary natural yellow pigment derived from the rhizome of the herb Curcuma longa (Zingiberaceae)...

Angiosarcomas are highly malignant and rare tumors of vascular or lymphatic endothelial cell origin with a poor prognosis. Lymphangiosarcoma associated with chronic lymphedema is known as Stewart-Treves syndrome. Stewart-Treves syndrome is primarily described in patients with lymphedema of an upper extremity occurring after breast cancer surgery including radical axillary lymph node dissection and subsequent radiotherapy. It is rarely described in the presence of idiopathic chronic lymphedema of the lower extremities...

The transcriptional regulation of the human epidermal growth factor receptor-2 (HER2) contributes to an enhanced HER2 expression in HER2-positive breast cancers with HER2 gene amplification and HER2-low or HER2-negative breast cancers following radiotherapy or endocrine therapy, and this drives tumorigenesis and the resistance to therapy. Epigenetic mechanisms are critical for transcription regulation, however, such mechanisms in the transcription regulation of HER2 are limited to the involvement of tri-methylated histone 3 lysine 4 (H3K4me3) and acetylated histone 3 lysine 9 (H3K9ac) at the HER2 promoter region...

Sentinel lymph node biopsy and ACOSOG-Z0011 criteria have modified axillary treatment in breast cancer surgery. We performed a systematic review of studies assessing the impact of axillary treatment on survival. The search showed 6891 potentially eligible items. Of them, 23 clinical trials and 12 meta-analyses published between 1980 and 2017 met the study criteria. The review revealed that axillary lymph node dissection (ALND) can be omitted in patients pN0 and pN1mic, without compromising survival. In patients pN1 it is proposed not to treat the axilla or replace ALND for axillary radiotherapy...

PURPOSE: Radiation therapy is proven to reduce local recurrence in patients with early-stage breast cancer. To reduce toxicity, treatment time, and improve accuracy, intraoperative radiation therapy was used as definitive treatment or as a boost. The study's objective was to compare the short-term toxicity and cosmesis of single-fraction (SF) IORT and hypofractionated radiotherapy with IORT boost (HfB) given as definitive treatment. METHODS AND MATERIALS: Between March 2011 and December 2013, 57 patients aged 45-91 years and 24 patients aged 43-83 years (total n = 81) with Stage 0-II were treated with SF or HfB (Mobetron, IntraOp Medical, Sunnyvale, CA)...

BACKGROUND: For clinical T1-2N0 breast cancer, sentinel lymph node biopsy (SLNB) has been shown in American College of Surgeons Oncology Group (ACOSOG) Z0011 to be sufficient for women with 1 to 2 positive sentinel lymph nodes with no added benefit for completion axillary lymph node dissection (ALND). Z0011 specified whole breast radiotherapy (RT) using standard tangential fields; however, later analysis showed variation in field design. We assessed nationwide practice patterns and examined factors associated with patients undergoing completion ALND and subsequent radiation field design...

INTRODUCTION: Derived from heavy chain only camelid antibodies, ~15-kDa single-domain antibody fragments (sdAbs) are an attractive platform for developing molecularly specific imaging probes and targeted radiotherapeutics. The rapid tumor accumulation and normal tissue clearance of sdAbs might be ideal for use with (211)At, a 7.2-h half-life α-emitter, if appropriate labeling chemistry can be devised to trap (211)At in cancer cells after sdAb binding. This study evaluated two reagents, [(211)At]SAGMB and iso-[(211)At]SAGMB, for this purpose...

Despite significant advances in combinations of radiotherapy and chemotherapy, altered fractionation schedules and image-guided radiotherapy, many cancer patients fail to benefit from radiation. A prevailing hypothesis is that targeting repair of DNA double strand breaks (DSBs) can enhance radiation effects in the tumor and overcome therapeutic resistance without incurring off-target toxicities. Unrepaired DSBs can block cancer cell proliferation, promote cancer cell death and induce cellular senescence. Given the slow progress to date translating novel DSB repair inhibitors as radiosensitizers, we have explored drug repurposing, a proven route to improving speed, costs and success rates of drug development...

MicroRNA-200c (miR-200c) recently was found to have tumor-suppressive properties by inhibiting the epithelial-mesenchymal transition (EMT) in several cancers. miR-200c also interacts with various cellular signaling molecules and regulates many important signaling pathways. In this study, we investigated the radiosensitizing effect of miR-200c and its mechanism in a panel of human cancer cell lines. Malignant glioma (U251, T98G), breast cancer (MDA-MB-468), and lung carcinoma (A549) cells were transfected with control pre-microRNA, pre-miR-200c, or anti-miR-200c...

Vivek Verma, Charles B Simone, Mark V Mishra
Background: As costs of cancer care rise, the importance of documenting value in oncology increases. Proton beam radiotherapy (PBT) has the potential to reduce toxicities in cancer patients, but is relatively expensive and unproven. Evaluating quality of life (QOL) and patient-reported outcomes (PROs) is essential to establishing PBT's "value" in oncologic therapy. The goal of this systematic review was to assess QOL and PROs in patients treated with PBT. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-guided systematic searches were conducted...

BACKGROUND: Concurrent chemoradiotherapy could increase the local control rate in patients with high recurrence risk after breast-conserving surgery, but the effect of concurrent chemoradiotherapy after mastectomy and axillary dissection is not clear. The aim of the study was to compare the effects of late-course concurrent chemoradiotherapy (CCRT) versus sequential therapy (SCRT) after mastectomy and axillary surgery in locally advanced breast cancer. METHODS: This was a randomized controlled trial of 155 patients with stage pT3-4p N1-3c M0 or pAnyT pN2-3c M0 breast cancer undergoing 5-fluorouracil+epirubicin+cyclophosphamide followed by docetaxel (FEC-D) chemotherapy after mastectomy and axillary dissection...

BACKGROUND: Surgery for the primary tumor in metastatic breast cancer is usually not recommended, assuming that local therapy provides no advantage. Recent reports suggest a survival improvement after locoregional treatment, but this is still controversial. We aimed to evaluate the effectiveness of locoregional treatment in primary metastatic breast cancer and to determine associated factors. METHODS: A retrospective analysis of 39 women with de novo metastatic breast cancer at Hospital Universitario La Paz, from January-2012 to June-2016 grouped by locoregional treatment (n=23) or not (n=16)...
