PURPOSE: To investigate whether treatment (surgery, radiation therapy, and endocrine therapy) contributes to racial disparities in outcomes of ductal carcinoma in situ (DCIS). PATIENTS AND METHODS: The analysis included 8184 non-Hispanic White and 954 non-Hispanic Black women diagnosed with DCIS between 1996 and 2011 and identified in the Missouri Cancer Registry. Logistic regression models were used to estimate odds ratios (ORs) of treatment for race. We used Cox proportional hazards regression models to estimate hazard ratios (HRs) of ipsilateral breast tumor (IBT) and contralateral breast tumor (CBT) for race...

BACKGROUND: Few descriptive epidemiological studies on the incidence, treatment and survival can accurately reflect a whole population. Manitoba, Canada has an accurate cancer registry, a drug information program network and a breast screening program since 1995. This combined with a stable population provides true population data that can accurately describe the region. METHODS: Using a retrospective cohort design all Breast Cancer cases were obtained from 2004-2010 (N=5399) and grouped by Intrinsic sub-type...

BACKGROUND: Identifying DCIS patients at low risk for disease progression could obviate need for standard therapy. The LORIS (surgery versus active monitoring for low-risk DCIS) trial is studying the safety of monitoring low-risk DCIS, although ipsilateral breast tumor recurrence (IBTR) rates in patients meeting enrollment criteria after complete surgical excision are unknown. METHODS: Women with pure DCIS treated with breast-conserving surgery (BCS) with/without radiation therapy (RT) from 1/1996-1/2011 were included from a prospectively maintained database...

PURPOSE: Inflammatory breast cancer (IBC) is rare and associated with a poor prognosis. Following neoadjuvant chemotherapy or endocrine therapy, the multidisciplinary team selected a small number of patients for breast-conservation therapy (BCT). The aim of this study was to determine the outcome of IBC patients treated with BCT in Edinburgh. METHODS: Between January 1999 and December 2013, thirty-five women with IBC were treated by BCT. The median follow-up was 80 months...

Gastric metastasis is rare but it can be the initial symptom of cancer. The second leading cause of this type of metastasis is breast cancer. A lack of clinical signs and nonspecific side effects of the treatment of primary tumors can lead to the misdiagnosis of metastatic gastric cancer. Upper gastrointestinal endoscopy with biopsy and immunohistochemistry should be used for diagnosis. Treatment is palliative; it includes chemo, endocrine, and radiation therapies. Four patients with breast cancer and gastric metastasis were identified...

INTRODUCTION: It is generally accepted that estrogens play a protective role in cognitive function. Therefore, it can be expected that subtotal estrogen deprivation following aromatase inhibition will alter cognitive performance. METHODS: In a cross-sectional study we investigated 80 postmenopausal women with breast cancer. Memory and spatial cognition were compared across 4 treatment groups: tamoxifen only (TAM, n = 22), aromatase inhibitor only (AI, n = 22), TAM followed by AI ('SWITCH group', n = 15), and patients with local therapy (LT) only (surgery and radiation, n = 21)...

PURPOSE: In 2004, The National Comprehensive Cancer Network (NCCN) Guidelines incorporated omission of radiation therapy after breast-conservation surgery in women ≥70 years old with stage I, estrogen receptor-positive breast cancer who plan to receive endocrine therapy. One study demonstrated wide variation in implementing this change across 13 NCCN institutions. We evaluated the practice pattern at our institution. METHODS: We identified women ≥70 years old treated at our institution from 2009 to 2014...

PURPOSE: The role of postmastectomy radiotherapy in the treatment of T1-2 primary tumor with 1-3 positive lymph nodes is controversial. We compared treatment outcomes between breast conserving surgery followed by radiotherapy (BCS+RT) and total mastectomy alone (TM) in the setting of modern adjuvant systemic treatments. METHODS: Patients with T1-2 primary breast cancer and 1-3 positive lymph nodes who were treated between 2001 and 2011 were divided into 2 groups based on the treatment approach: BCS+RT (n = 169) and TM (n = 117)...

It is known that four main molecular breast cancer subtypes have different prognoses and different responses to therapy. Luminal A tumours have a better prognosis and they tend to be sensitive to anti-estrogen drugs. Luminal B tumours have incomplete sensitivity to endocrine therapy. Her2 tumours, which have an aggressive natural history, are sensitive to trastuzumab. Finally, basal-like tumours might be eligible for chemotherapy. The aim of this study was to evaluate the chemosensitivity to docetaxel and doxorubicin of breast cancer subtypes...

With the widespread adoption of population-based breast cancer screening, ductal carcinoma in situ (DCIS) has come to represent 20-25% of all breast neoplastic lesions diagnosed. Current treatment aims at preventing invasive breast cancer, but the majority of DCIS lesions will never progress to invasive disease. Still, DCIS is treated by surgical excision, followed by radiotherapy as part of breast conserving treatment, and/or endocrine therapy. This implies over-treatment of the majority of DCIS, as less than 1% of DCIS patients will go on to develop invasive breast cancer annually...

BACKGROUND: The American College of Surgeons Oncology Group Z1031 trial demonstrated that neoadjuvant endocrine therapy (NET) increased breast-conserving surgery (BCS) rates for postmenopausal patients with clinical tumor stage 2-4c estrogen receptor-positive breast cancer. We evaluated national trends in NET use in relation to the conduct of the Z1031 trial and the impact of NET on the rates of BCS. METHODS: Using the National Cancer Data Base (NCDB), we identified all cT2-4c hormone receptor (HR)-positive breast cancer patients age ≥50 years from 2004 to 2012...

INTRODUCTION: Pulmonary tumor thrombotic microangiopathy (PTTM) is rare, cancer-related pulmonary complication leading to hypoxia, pulmonary hypertension, and heart failure. The standard treatment for PTTM is not established. However, imatinib, a tyrosine kinase inhibitor of the PDGF receptor, may cause regression of pulmonary hypertension and pulmonary artery remodeling in PTTM. CASE DESCRIPTIONS: We report two cases of PTTM who received an anti-PDGF agent of imatinib for PTTM developed during chemotherapy for metastatic breast cancer...

PURPOSE/OBJECTIVE(S): After breast conserving surgery, adjuvant radiation therapy represents the standard of care for most patients. However, multiple options exist beyond standard fractionated whole breast irradiation including hypofractionated whole breast irradiation (HFRT), accelerated partial breast irradiation (APBI), and endocrine therapy (ET) alone, which can limit treatment duration, and potentially reduce morbidity and cost. Limited data are available on the percentage of patients eligible for these alternatives; therefore, a Surveillance Epidemiology and End Results (SEER) analysis was performed to assess candidacy for these alternative options in women with early stage breast cancer...

Ductal carcinoma in situ (DCIS), once a rare entity, now comprises up to 30% of newly diagnosed breast cancers detected on mammography. It is now appreciated as a widely heterogeneous disease, with indolent lesions of minimal clinical significance on one end of the spectrum, and aggressive lesions with malignant invasive potential on the other. Therefore, the traditional guideline-concordant approach to treatment with surgery, radiation, and endocrine therapy may lead to overtreatment of certain patients, and insufficient treatment of others...

BACKGROUND: Few studies have been performed on post-relapse survival in patients with the early and late distant recurrence in estrogen receptor (ER)-positive, HER2-negative breast cancer. METHODS: A total of 205 patients with the early distant recurrence and 134 patients with the late distant recurrence of ER-positive, HER2-negative breast cancer who had undergone breast surgery or neoadjuvant chemotherapy between January 2000 and December 2004 were registered from nine institutions...

Monitoring recurrence and evaluating response to therapy are important aspects of clinical decision making in the treatment of breast cancer. In this literature review, the authors highlight several of the key areas where integrated fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) measurements are anticipated to have a significant impact on monitoring recurrence and evaluating response to therapy. These areas include comparing FDG PET/CT with conventional imaging for detecting breast cancer metastases; evaluating the role of FDG PET/CT in the presence of elevated tumor markers during follow-up period after the primary surgery; using FDG PET/CT to assess response to neoadjuvant chemotherapy (NAC), targeted and endocrine therapies; using FDG PET/CT to predict response to NAC according to different molecular phenotypes of breast cancer; and applying PET/CT and some new breast-related PET tracers to evaluate response to anticancer treatment...

PURPOSE OF REVIEW: In this review, we summarize recent and current biomarkers and assays that are being considered in the selection of suitable patients with estrogen receptor-positive early breast cancer for extended (years 5-10) adjuvant endocrine therapy (AET). RECENT FINDINGS: Women with estrogen receptor-positive early-stage breast cancer (65% of cases) continue to have late risk for distant recurrence extending beyond 5 years from surgery. Recent large trials have consistently demonstrated improvement for prolonging endocrine therapy...

BACKGROUND: The standard of care for elderly women with breast cancer remains controversial. The aim of this study was to clarify the management of elderly breast cancer patients who undergo surgery. MATERIALS AND METHODS: This retrospective single-center cohort study included 2276 breast cancer patients who underwent surgery between 1993 and 2014. The patients were divided into three groups according to age: ≤64 y (young), 65-74 y (older), and ≥75 y (elderly)...

BACKGROUND: Patients with a diagnosis of early-stage breast cancer are offered the option of either mastectomy or breast-conserving therapy (BCT) secondary to multiple randomized trials demonstrating equivalent long-term outcomes. Traditionally, BCT has used standard whole-breast irradiation (SWBI) after breast-conserving surgery, although several alternatives have emerged during the past few decades. METHODS: This report reviews key studies supporting each radiation technique and its respective eligibility criteria to assist clinicians in deciding which adjuvant radiotherapy options are appropriate for their patients...

BACKGROUND: This study aims to determine the role of patient expectations as potentially modifiable factor of side-effects, quality of life, and adherence to endocrine treatment of breast cancer. PATIENTS AND METHODS: A 2-year prospective clinical cohort study was conducted in routine primary care with postoperative patients with hormone-receptor-positive breast cancer, scheduled to start adjuvant endocrine treatment. Structured patient-reported assessments of side-effects, side-effect expectations, quality of life, and adherence took place during the first week post-surgery and after 3 and 24 months of endocrine treatment...
