What are the main findings? Response: Our study identified PTK6 as a critical gene regulating survival of ER+ breast cancer cells. PTK6 inhibition also suppresses growth and survival of ER+ breast cancer cells that are resistant to the effects of therapies commonly used to treat patient ER+ breast cancers, making PTK6 an attractive candidate therapeutic target for these resistant cancers.

What are the main findings? Response: The new 2017 ASCO guidelines for the use bone-modifying in individuals with bone metastases recently endorsed every 3-month zoledronic, because of high level evidence from three randomized trials, including our trial (published in Jama in Jan 2017, first author Himelstein et al) that giving zoledronic acid every 3-months was non-inferior to the standard of monthly zoledronic. The guidelines also concluded that there was not one preferred bone modifying agent of the other, despite the fact the comparing monthly zoledronic to monthly denosumab in women with bone metastases, denosumab delayed the time to first skeletal-related event (pathological fractures, necessity for radiation or surgery, and spinal cord compression) and subsequent events by 23% (or in absolute terms about 3 months) . Zoledronic acid became generic in 2013, whereas monthly denosumab is still patented until 2022-25.

MedicalResearch.com Interview with: [caption id="attachment_37960" align="alignleft" width="112"]Dr Hongchao Pan PhD Medical Research Council Population Health Research Unit Clinical Trial Service Unit & Epidemiological Studies Unit Nuffield Department of Population Health Oxford  Dr Hongchao Pan[/caption] Dr Hongchao Pan PhD Medical Research Council Population Health Research Unit Clinical Trial Service Unit & Epidemiological Studies Unit Nuffield Department of Population Health Oxford MedicalResearch.com: What is the background for this study? What are the main findings? Response: We’ve known for a long time that recurrences can occur late in women with oestrogen receptor positive breast cancers. Our study aimed to assess how big the risk was for women who had taken endocrine treatment (tamoxifen or an aromatase inhibitor) for 5 years, which greatly reduces the risk of recurrence (by about a half during treatment and one third for the 5 years after stopping). We also wanted to find out what factors influenced the risk of recurrence, and whether some women had such a low risk that they could safely stop hormonal treatment after 5 years or, conversely, whether other women had a particularly high risk so it would make sense for them to keep on taking hormonal treatment. What we found by following the progress of over 60,000 women who had stopped hormonal treatment at 5 years is that the risk of the cancer spreading stays about the same for the next 15 years. This risk is much higher for women whose breast cancer had spread to the nodes when first diagnosed but even for those with the best outlook (no spread to the lymph nodes and small tumours), there was a 10% chance of cancer spread over 15 years.

What are the main findings? Response: The burden of cancer among young adults has been rarely studied in depth. To our knowledge, we describe for the first time the scale and profile of cancer incidence and mortality worldwide among 20-39 year-olds, highlighting major patterns by age, sex, development level, and geographic region. Although cancer is less frequent than that observed at older ages, its impact remains considerable because these individuals have a large proportion of their expected lifespans remaining, contribute substantially to the economy, and play a major role in caring for their families. Worldwide, almost 1 million new cases of cancer and 400 000 cancer-related deaths occurred among young adults aged 20–39 years in 2012. Overall, the most common cancer types in terms of new cases were female breast cancer, cervical cancer, thyroid cancer, leukemia, and colorectal cancer, and the most common types of cancer-related deaths were those due to female breast cancer, liver cancer, leukemia, and cervical cancer. The burden was disproportionately greater among women, with an estimated 633 000 new cancer cases (65% of all new cancer cases in that age group) and 194 000 cancer-related deaths (54% of all cancer-related deaths in that age group) in 2012.

Response: This study aimed at evaluating the safety of pregnancy after breast cancer particularly in patient with history of ER+ breast cancer; a subset in which safety of future pregnancy is always put into question by oncologists and obstetricians. This study included more than 300 pregnant women and 800 non-pregnant breast cancer patients who acted as a comparator group The results show that after more than 7 years after pregnancy, women who became pregnant did not have an increased risk of recurrence compared to those who did not become pregnant irrespective of ER status. There was no impact of breastfeeding, abortion or time of pregnancy on patient outcome.

Malmgren, PhD President, HealthStat Consulting, Inc Epidemiology Department University of Washington MedicalResearch.com: What is the background for this study? What are the main findings? Response: Metastatic breast cancer (MBC) has two types, de novo stage IV MBC discovered to be metastatic at initial diagnosis as advanced disease and recurrent MBC found on follow up after diagnosis and treatment for initial invasive breast cancer. Our institutional breast cancer registry tracks both de novo metastatic breast cancer and invasive breast cancer for distant metastases. With this information we were able to compare the presentation, treatment and outcomes of both types, something that is not possible in national SEER data as recurrent MBC is not tracked. We found a remarkable improvement in 5-year survival from 28% to 55% over time among the de novo metastatic breast cancer patients.  Recurrent MBC 5-year survival did not improve in the same time period (23% to 13%) although incidence of recurrent MBC fell from 18% to 7% from 1990 to 2010. Incidence of recurrent metastatic breast cancer hormone receptor and HER2 positive breast cancer declined the most, leaving a large number of triple-negative recurrent metastatic breast cancer cases in the most recent time period. Worse metastatic breast cancer survival was associated with recurrent vs. de novo MBC, hormone receptor negative disease, older age (70+) and visceral dominant disease. HER2 positive disease was associated with better outcomes.

What are the main findings? Response: Image-guided biopsies that we perform based on suspicious findings on mammography can yield one of three pathology results: cancer, high-risk, or benign. Most high-risk breast lesions are noncancerous, but surgical excision is typically recommended because some high-risk lesions can be upgraded to cancer at surgery. Currently, there are no imaging or other features that reliably allow us to distinguish between high-risk lesions that warrant surgery from those that can be safely followed, which has led to unnecessary surgery of high-risk lesions that are not associated with cancer. We decided to apply machine learning algorithms to help us with this challenging clinical scenario: to distinguish between high-risk lesions that warrant surgery from those that can be safely followed. Machine learning allows us to incorporate the full spectrum of diverse and complex data that we have available, such as patient risk factors and imaging features, in order to predict which high-risk lesions are likely to be upgraded to cancer and, ultimately, to help our patients make more informed decisions about surgery versus surveillance. We developed the machine learning model with almost 700 high-risk lesions, then tested it with more than 300 high-risk lesions. Instead of surgical excision of all high-risk lesions, if those categorized with the model to be at low risk for upgrade were surveilled and the remainder were excised, then 97.4% malignancies would have been diagnosed at surgery, and 30.6% of surgeries of benign lesions could have been avoided.

What are the main findings? Response: Both the American Cancer Society (ACS) and the U.S. Preventive Services Task Force (USPSTF) have stated that women in their 40s--or, in the case of ACS, women ages 40-44--should have the choice to decide when they want to start screening for breast cancer. These organizations recommend that women in this age group weigh the benefits and risks of mammography screening, with the goal of making an informed decision about when to start screening. Yet recent research has shown that women are more aware of the benefits of mammography screening than the harms, including overdiagnosis and overtreatment (doi:10.1001/jamainternmed.2017.2247). We therefore wondered whether women actually have the information they need to make informed screening decisions. In a population-based sample of 429 U.S. women ages 35-55, we found that awareness of breast cancer overdiagnosis (16.5%) and overtreatment (18.0%) was low. Moreover, we found that most women did not find statements about these harms to be believable and persuasive.

What are the main findings? Response: The Phase III MONALEESA-2 trial was the primary study that supported the recent European approval of Kisqali (ribociclib). Findings from the study showed superior efficacy and demonstrated safety of Kisqali plus letrozole compared to letrozole alone in postmenopausal women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) locally advanced or metastatic breast cancer who received no prior therapy for their advanced breast cancer. The trial showed Kisqali plus letrozole reduced the risk of progression or death by 43% versus letrozole alone. At a pre-planned analysis, Kisqali plus letrozole demonstrated a median progression-free survival (PFS) of 25.3 months compared to 16.0 months for letrozole alone (HR=0.568 (95% CI: 0.457-0.704; p<0.0001)). More than half of patients (55%) with measurable disease taking Kisqali plus letrozole experienced a tumor reduction of at least 30%. Finally, Kisqali plus letrozole demonstrated rapid clinical improvement in patients with measurable disease, with 76% seeing a reduction in tumor size after only eight weeks versus 67% with letrozole alone. Most side effects in the MONALEESA-2 trial were mild to moderate in severity, identified early through routine monitoring, and generally managed through dose interruption and/or reduction. The most common grade 3/4 adverse events (reported at a frequency ≥5%) for Kisqali plus letrozole compared to letrozole alone were neutropenia (60% vs 1%, respectively), leukopenia (21% vs 1%), hypertension (10% vs. 11%), increased alanine aminotransferase level (9% vs. 1%), lymphopenia (7% vs. 1%) and increased aspartate aminotransferase level (6% vs. 1%).

What are the main findings? Response: The links between hyperlipidaemia and cancer has been exciting scientists in recent years.  We have previously shown an association with breast cancer and hyperlipidaemia using a cross-sectional dataset in 2014. In 2016 we showed that in patients with the four main cancers in the UK (namely Breast, Lung, Colon and Prostate) that the presence of hyperlipidaemia improved the long term mortality and prognosis of these patients.  In this study utilising a big data, longitudinal study methodology, we looked at 16043 healthy women above the age of 40 with hyperlipidaemia and compared these to an age and gender matched control sample of 16043 healthy women without high cholesterol. We then followed up these patients and found that subsequent breast cancer rates in the women with hyperlipidaemia were 45% lower. Subsequent mortality in those patients who developed breast cancer was also 40% lower in the hyperlipidaemia group compared to the non-hyperlipidaemia controlled sample.

Lee Moffitt Cancer Center & Research Institute Tampa, FL 33612 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although radiation therapy after breast-conserving surgery for early-stage breast cancer has significantly improved patient prognosis, many patients will face a second cancer diagnosis within 20 years of primary treatment. Experimental and clinical studies have shown that local radiation therapy can activate an immune response that can propagate systemically to attack distant untreated metastases. However, current radiotherapy practice has not specifically focused on enhancing immune responses. We asked the question if pre-operative irradiation, when applied to the bulk of disease, could have potentially higher immune stimulatory effects. To study this, we analyzed historic outcomes of breast cancer patients treated with either adjuvant (radiation after surgery) or neoadjuvant (radiation before surgery) radiotherapies. Our analysis showed that the risk of developing a second tumor after neoadjuvant compared with adjuvant RT was significantly lower, especially for estrogen receptor-positive women who underwent breast conserving surgery or mastectomy. Historic data revealed an increase in disease-free survival of 12% over 20 years after treatment of the original tumor.

Jacobs MD Johns Hopkins School of Medicine Baltimore, Maryland Dr. Jacobs[/caption] Dr. Lisa K. Jacobs MD Johns Hopkins School of Medicine Baltimore, Maryland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Breast preservation is the preferred treatment for many women diagnosed with breast cancer.  The most common question that a patient will ask after the surgery is, “Did you get it all?” In the ideal case, this is accomplished in a single outpatient surgery with very good cosmetic results.  In our study, Beyond the Margins-Economic Costs and Complications Associated with Repeated Breast-Conserving Surgeries we evaluated the detrimental effects of an unsuccessful initial surgery due to positive surgical margins. Using private insurance claims data, we found that 16% of patients planning breast preservation required a second breast-conserving surgery and an additional 7% converted to mastectomy.  Of those patients that required additional surgery there was a 56% ($16,072) increase in cost and a 48% increase in complications.  Those complications include infection, hematoma, seroma, and fat necrosis.  This study demonstrates that repeated surgery has not only cosmetic consequences, but also has financial implications and increased risk.

Komen Interdisciplinary Breast Fellowship Program The University of Texas MD Anderson Cancer Center Houston, TX MedicalResearch.com: What is the background for this study? Response: The MONALEESA-2 trial is a double-blind, randomized, Phase III trial that evaluated efficacy and safety of Kisqali plus letrozole compared to letrozole alone in postmenopausal women with HR+/HER2- advanced breast cancer who had not previously been treated for their advanced disease. MedicalResearch.com: What are the main findings? o Updated findings from the Phase III MONALEESA-2 trial confirm the efficacy and safety of Kisqali® (ribociclib) plus letrozole as a treatment option for HR+/HER2- advanced or metastatic breast cancer: • After nearly one year of additional follow-up, Kisqali plus letrozole demonstrated median progression-free survival (PFS) of 25.3 months (95% CI: 23.0-30.3) compared to 16.0 months (95% CI: 13.4-18.2) for letrozole alone. • The progression-free survival rate at two years was 54.7% in the Kisqali plus letrozole arm compared to 35.9% in patients treated with letrozole alone. • In women with measurable disease, 55% of patients saw their tumor size shrink by at least 30% (overall response rate (ORR)) compared to 39% of patients with letrozole plus placebo. • Treatment benefit remained consistent across all patient subgroups regardless of demographics or disease characteristics, including women with visceral disease and those diagnosed de novo. o The safety profile of Kisqali plus letrozole remained consistent and the incidence of laboratory and electrocardiogram (ECG) irregularities were similar to that observed at the first interim analysis. • The most common grade 3/4 laboratory abnormalities for Kisqali plus letrozole compared to letrozole alone were decreased neutrophils (62.6% vs 1.5%), decreased leukocytes (36.8% vs 1.5%), decreased lymphocytes (16.2% vs 3.9%) and elevated alanine aminotransferase (11.4% vs 1.2%).

Hershey Medical Center Hershey, PA  Dr. Huesch[/caption] Marco D. Huesch, MBBS, PhD Department of Radiology Milton S. Hershey Medical Center Hershey, PA   MedicalResearch.com: What is the background for this study? Response: Public health depends on coordinated actions between patients, payors and providers. Important preventative care and evidence-based screenings need to be understood and sought out by patients, need to be reimbursed by or subsidized by insurance plans, and offered and recommended by physicians and care team members. Women’s breast health is a good example of how – in theory – all these come together and allow women to obtain regular screenings for breast cancer through mammograms. Yet it is commonly accepted that perhaps as many as 1 in 3 women are not adequately screened or are not screened at all. In this study we hypothesized that a prominent global celebrity, Ms Angelina Jolie’s, highly public announcement of her own risk-reducing surgery to prevent breast cancer and her recommendation to women to understand whether they were at high risk might spur uptake of breast screenings at our institution.

What are the main findings? Response: This study is the largest immunotherapy study to date presented in metastatic triple negative breast cancer. This phase 2 trial studied the efficacy and safety of pembrolizumab (P) as single agent in a very aggressive disease and had two cohorts, a cohort of previously untreated patients (Cohort B) and a cohort with patients who had received prior chemotherapy lines in the metastatic setting (Cohort A). The study showed that single agent pembrolizumab can elicit durable responses in a subset of patients. This was found regardless of tumoral PD-L1 expression but appeared to be much more frequent in women without prior chemotherapy treatments in the metastatic setting. Survival is especially promising for patients responding to therapy.

Response: Although we know that bigger surgery does not result in better patient outcomes in breast cancer, since 2005 rates of lumpectomy have been decreasing accompanied by an increase in bilateral mastectomy for unilateral cancer. High rates of second surgery after initial lumpectomy are one deterrent for patients. In 2013 the SSO and ASTRO developed an evidence based consensus guideline endorsing no ink on tumor as the standard negative margin width for women with stage 1 and 2 cancer having breast conserving surgery with whole breast irradiation. The purpose of our study was to examine time trends in the use of additional surgery after lumpectomy before and after guideline dissemination and to determine the impact of these trends on final rates of breast conservation.

Trastuzumab therapy has been shown to improve survival in patients with early-stage and metastatic her-2 positive breast cancer. In this study, we compared the safety and efficacy of the trastuzumab originator (Herceptin) to a trastuzumab biosimilar (CT-P6) in patients with stage I-III HER-2 positive breast cancer receiving neoadjuvant chemotherapy. The study was a randomized phase III trial. We found the pathological complete response rates were similar in both groups. Both antibodies were safe. Pharmacokinetic studies showed similar plasma concentrations for the trastuzumab originator and the proposed biosimilar.

What are the main findings? Response: About one-third of all women diagnosed with breast cancer undergo mastectomy. In recent years, owing to advancements in screening and treatment, life expectancy after being diagnosed with breast cancer has increased. Research has shown that for patients who undergo mastectomy, breast reconstruction offers many psychological benefits such as improved self-esteem, reduced sexual dysfunction, decreased anxiety, and overall improvement in quality of life. After the passage of the Women’s Health and Cancer Rights Act in 1998, the coverage of post-mastectomy breast reconstruction (PBR) by any type of health insurance became mandatory. However, there are large and widening racial and ethnic disparities in PBR, with White women having a higher rate of PBR than women from other racial and ethnic groups. In 2011, the State of New York enacted a law mandating that surgeons advise their patients undergoing mastectomy about available breast reconstruction options, insurance coverage, and referral to a plastic surgeon. We evaluated the effect of this law on racial/ethnic disparities in immediate PBR. Our results did not show any effect on the overall rate of immediate  post-mastectomy breast reconstruction or on disparities between white and African-American women; however, we found that White-Hispanic and White-other racial/ethnic group disparities in immediate PBR were reduced by 9 and 13 percentage points, respectively. This is a substantial reduction in disparity within only a year after the passage of the law, which demonstrates the importance of physician-patient communication.

Response: More than 22,000 women younger than 45 years of age were diagnosed with breast cancer in 2013. Although less than 10 percent of all breast cancers are diagnosed among women younger than age 45, the types of breast cancer these younger women face are typically more aggressive, are diagnosed at more advanced stages, and result in poorer survival compared to breast cancer in older women. Younger women may also require more intense treatment, exhibit cancers that are less responsive to treatment, and have distinct and more prevalent side effects from treatment than older women. These side effects can include poorer quality of life, fertility problems, and depression. As a result, breast cancer treatment for younger women is expensive, making them vulnerable to financial hardship. Recent research has shown that 31.8 percent of cancer survivors are likely to have cancer treatment-induced financial troubles, with higher rates among younger cancer patients. These financial difficulties cause some survivors to forego or delay necessary medical treatments.

MedicalResearch.com Interview with: Cindy S. Lee, MD Department of Radiology and Biomedical Imaging University of California, San Francisco, San Francisco Now with Department of Radiology NYU Langone Medical Center, Garden City, New York MedicalResearch.com: What led you and colleagues to conduct this study? Response: I am a breast imager. I see patients who come in for their screening mammograms and I get asked, a lot, if patients aged 75 years and older should continue screening, because of their age. There is not enough evidence out there to determine how breast cancer screening benefits women older than 75. In fact, all previously randomized trials of screening mammography excluded people older than 75 years. Unfortunately, age is the biggest risk factor for breast cancer, so as patients get older, they have higher risks of developing breast cancer. It is therefore important to know how well screening mammography works in these patients.

Kuerer, MD, PhD, FACS Executive Director, Breast Programs MD Anderson Cancer Network PH and Fay Etta Robinson Distinguished Professor in Cancer Research Dept of Breast Surgical Oncology Director, Breast Surgical Oncology Training Program MedicalResearch.com: What is the background for this study? Response: Neoadjuvant chemotherapy (NCT) has the ability to confer a pCR (pathologic complete response-when no residual cancer is found) in both the breast and axillary lymph nodes. We know that this is most likely to occur in women with HER2 positive and triple negative disease. The high rate of pCR among these patients raises the question of whether surgery is still required, particularly among those who will receive adjuvant radiation therapy. Until recently, we lacked the ability to pre-operatively predict patients who achieved a breast pCR. Recently, we completed a clinical feasibility trial examining the ability of image-guided biopsy to predict a pCR after neoadjuvant chemotherapy. Our biopsy technique was able to accurately predict a pCR in 98% of patients with only a 5% false negative rate. Based upon these findings, we believe we can accurately determine which patients achieve a breast pCR. This led us to develop a clinical trial to see if breast surgery is redundant in patients who achieve a pCR. An important question that remained was if we are going to omit breast surgery in these exceptional responders, can we also omit axillary surgery?

Chan School of Public Health Boston, MA 02115 Dr. Trudel-Fitzgerald[/caption] Claudia Trudel-Fitzgerald Ph.D.  FRQS Postdoctoral research fellow & Clinical psychologist (OPQ) Department of Social and Behavioral Sciences Harvard T.H. Chan School of Public Health Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is very limited research on the association between sleep characteristics and survival among individuals with cancer. However, this is an important question, especially among breast cancer patients because sleep disturbances are frequently reported by these women. Preliminary studies have suggested that sleep duration is related to mortality. The novel findings of our research indicate that not only sleep duration, but also changes in sleep duration before versus after diagnosis, as well as regular difficulties to fall or stay asleep, may also be associated with mortality among women with breast cancer over a period of up to 30 years.

MedicalResearch.com Interview with: [caption id="attachment_33870" align="alignleft" width="191"]Molly MacDonald Molly MacDonald[/caption] Molly MacDonald Founder/President/CEO SurThrivor™ MedicalResearch.com: Would you tell us a little about yourself, especially your life before/outside of your cancer diagnosis?  Response: My life before cancer was a struggle of a different sort.  In 1997 I drove up the driveway to our lovely home with five children ages 4-13 safely strapped into the back of my gus guzzling suburban.  As I approached the front of the house, I noticed a small paper, about the 4X10 inches tacked to our front door, and where we lived no one tacked notes to the front door and all service providers went around to the side. Pulling it off I read that the house was to auctioned off in 30 days.  That night I had a very unpleasant conversation with my husband during which I learned the deal he was pursuing, among other things, had not come to fruition and he was fronting it with our assets. Within a monthI liquidated what I could, rented a house for cash and began the process of transitioning our lives from a life of luxury to living paycheck to paycheck. Trying to find work, while navigating a nasty divorce and helping my children adjust was a huge challenge.

MedicalResearch.com Interview with: [caption id="attachment_33719" align="alignleft" width="191"]Poulikos I. Poulikakos, PhD Assistant Professor Department of Oncological Sciences Department of Dermatology The Tisch Cancer Institute Icahn School of Medicine at Mount Sinai Dr. Poulikakos[/caption] Poulikos I. Poulikakos, PhD Assistant Professor Department of Oncological Sciences Department of Dermatology The Tisch Cancer Institute Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: Mutations in the oncoprotein kinase BRAF are found in about 8% of human tumors, including more than 50% of melanomas. Small molecule RAF inhibitors prolonged survival of melanoma patients with mutant-BRAF tumors, but resistance limits their effectiveness. Further, RAF inhibitors showed only modest efficacy in patients with colorectal and thyroid mutant-BRAF tumors. Previous studies have suggested that the complex biochemical mechanisms of action of RAF inhibitors account for both sensitivity and major mechanisms of resistance to these drugs. Recently, a number of next generation RAF inhibitors have entered preclinical or clinical development, but the most appropriate clinical context for their use remained elusive.

Associate Professor Biomedical Diagnostic and Therapeutic Sciences, School of Health Sciences and Adjunct Associate Professor Department of Biological Sciences School of Health Sciences Oakland University Rochester, MI 48309. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Bisphenol-S (BPS), a substitute for bisphenol-A (BPA), has been suggested to be an endocrine disrupting compound interfering with normal hormonal activity. This bisphenol analogue is found in plastic substitutes, paper currency, and most products marked “BPA free.” Endocrine disrupting compounds interfere with the normal hormonal activity in the body. Bisphenols, specifically, disrupt the proper functioning of estrogen receptors, such as ERα causing interference with the normal activity of the hormone estrogen. Studies suggest BPS induces ERα pathways via its estrogen-mimicking properties in the body causing increased cell proliferation resulting in increased breast cancer risk. Despite the hope of a safer substitute, studies have shown that BPS exhibits similar estrogenic activity compared to its analogue BPA, due to their structural commonalities. BRCA1 is a commonly mutated gene in breast cancer; therefore, it is also important to study the effects of BPS on the expression of this protein. The potency of the endocrine disrupting abilities of BPS compared to BPA could show whether BPS is a suitable alternative to BPA in many everyday products. The results of this study may contribute to the understanding of the relationship between ERα, BRCA1 expression and Bisphenol-S in breast cancer treatment and prevention.

MedicalResearch.com Interview with: Ahmedin Jemal, DVM, PHD Vice President, Surveillance and Health Services Research American Cancer Society, Inc. Atlanta, GA 30303 MedicalResearch.com: What is the background for this study? Response: Previous studies reported that Contralateral Prophylactic Mastectomy (CPM) increased in the United States among women diagnosed with unilateral early-stage breast cancer with surgery without evidence for survival benefit. Previous studies also reported that receipt of this procedure is more common in younger than older patients, in white than in black patients, and in privately insured than uninsured patients. However, the extent of variation in receipt of CPM by state of residence was unknown.

MedicalResearch.com Interview with: Rebecca Nash, MPH Rollins School of Public Health Emory University MedicalResearch.com: What is the background for this study? Response: Contralateral prophylactic mastectomy (CPM) in women with invasive early-stage unilateral breast cancer has significantly increased in the U.S. over the past decade, despite the lack of evidence for a survival benefit. This procedure is particularly common among patients younger than 45 years old. It is also more common in whites compared to blacks, and in privately insured patients compared to uninsured or Medicaid insured patients. However, the extent of regional variation across the United States was unknown.

MedicalResearch.com Interview with: Anne Kuijer, MD Departments of Surgery and Radiology University Medical Center Utrecht and Thijs van Dalen, PhD Department of Surgery Netherlands Cancer Institute, Amsterdam MedicalResearch.com: What is the background for this study? What are the main findings? Response: In recent years it has become evident that clinicopathological factors fail to accurately determine prognosis in hormone receptor positive early stage breast cancer patients at intermediate risk of developing metastases. Gene-expression profiles, such as the 70-gene signature (MammaPrint) are therefore increasingly used for chemotherapy decision-making. In the current multicentre study we assessed the impact of 70-gene signature use on chemotherapy decisions in these patients. We demonstrated that, without the use of the 70-gene signature, half of patients was advised chemotherapy, which reflects the current controversy regarding chemotherapy benefit. Use of the 70-gene signature changed the chemotherapy advice in half of all patients and adherence to the 70-gene signature result was high.

MedicalResearch.com Interview with: [caption id="attachment_33012" align="alignleft" width="200"]Cary P. Gross, MD Section of General Internal Medicine Yale University School of Medicine New Haven, CT Dr. Cary Gross[/caption] Cary P. Gross, MD Section of General Internal Medicine Yale University School of Medicine New Haven, CT MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior work has demonstrated racial and socioeconomic disparities in breast cancer diagnosis, treatment, and outcomes.  As the oncology field has progressed over the past decade, the use of genetic testing to guide treatment decisions is one of the most exciting new developments. Our team was concerned that these new gene tests, which can offer important benefits, may have the potential to exacerbate disparities further.  That is, if there is unequal access to gene testing among patients for whom it is recommended, then our progress against cancer will not be equitably shared among people of all races and ethnicities.
