MedicalResearch.com Interview with: Takemi Tanaka, Ph. D. Professor, Stephenson Cancer Center Department of Pathology, School of Medicine University of Oklahoma Health Science Center MedicalResearch.com: What is the background for this study? Response: Our previous cohort study has shown that breast cancer progresses 60 days after diagnostic biopsy in early-stage ER+ breast cancer. Others have also reported increased breast cancer mortality due to surgery delay. These observations raised the question of how slow-growing ER+ breast cancer progresses so quickly in just 60 days following diagnosis, prompting us to hypothesize whether needle biopsy of breast tumors accelerates pro-metastatic changes.

Breast Cancer, Technology / 22.10.2023

Breast cancer accounts for 12.5% of new annual cases in the world, making it the most common of all cancers. Early detection is vital, since when breast cancer is localized, it boasts a 99% survival rate. Despite this fact, only 64% of breast cancer cases are detected at a localized stage in the US, according to data obtained from the National Breast Cancer Foundation. The good news is that scientists at MIT have developed a new device that can simply be incorporated into a bra. Doing so would allow more frequent monitoring of people with a high risk for breast cancer and it would enable women to detect very early stage tumors.
A Patch In Time
The device is a flexible patch that can be attached to any bra. It has an ultrasound tracker that can analyze breast tissue from various angles—and the images obtained are as high in quality as those obtained from ultrasound probes used in medical imaging clinics The device provides real-time information that is easy to access and interpret. The development of the device resulted from the personal experience of MIT associate professor. Canan Dagdeviren. The latter’s aunt was diagnosed with late-stage breast cancer at the age of 49, passing away six months later. While sitting by her aunt’s bedside, the researchers created a rough schematic of a diagnostic patch that could be incorporated into a brassiere. The aim was to enable women to obtain more frequent information instead of depending on a once-yearly (or less frequent) checkup. Dagdeviren’s device is essentially a miniature 3D-printed ultrasound scanner that has tiny openings. It can be rotated to obtain images from a plethora of angles, and does not require medical expertise to use. The device leverages the very latest technology, including AI algorithms, biomedical systems, and low-power circuits

MedicalResearch.com Interview with: Gabriele Martelli, MD Breast Unit, Surgery Fondazione IRCCS Istituto Nazionale dei Tumori Milan, Italy MedicalResearch.com: What is the background for this study? Response: Approximately 8% of breast cancer cases are associated with pathogenic germline variants of the BRCA1 or BRCA2 genes. Women with a pathogenic BRCA1 variant have lifetime risks of breast or ovarian cancer of 45% to 80% and 30% to 60%, respectively. Women with a pathogenic BRCA2 variant have lifetime risks of breast or ovarian cancer of 35% to 60% and 10% to 25%, respectively. BRCA1 breast cancer is often more aggressive than sporadic disease, while BRCA2 breast cancer is often of similar aggressivity to sporadic disease. However, few studies have investigated outcomes of breast-conserving surgery, prophylactic mastectomy, or prophylactic salpingo-oophorectomy in patients with BRCA1/2 breast cancer. We conducted a cohort study to assess outcomes of breast-conserving surgery vs mastectomy, prophylactic mastectomy vs no prophylactic mastectomy, and prophylactic salpingo-oophorectomy vs no prophylactic salpingo-oophorectomy in patients with BRCA1/2 breast cancer.

MedicalResearch.com Interview with: Mahdi Fallah, MD, PhD Study and Group Leader Risk Adapted Prevention (RAD) Group Division of Preventive Oncology National Center for Tumor Diseases (NCT) German Cancer Research Center (DKFZ) Heidelberg, Germany   MedicalResearch.com: What is the background for this study? Response: Breast cancer is a significant public health problem, being the most commonly diagnosed cancer and the second leading cause of cancer death in women in the US. Breast cancer screening from age 50 has been associated with a reduction in mortality and is recommended by the US Preventive Services Task Force. However, there is a significant disparity in mortality rates between Black and White individuals, with Black women having a higher death rate, especially before age 50. The current one-size-fits-all policy for breast cancer screening may not be equitable or optimal, and risk-adapted starting ages of screening based on known risk factors, such as race and ethnicity, may be recommended to optimize the benefit of screening. Our study aimed to provide evidence for a risk-adapted starting age of screening by race and ethnicity. (more…)

MedicalResearch.com Interview with:
Hyuna Sung, PHDHyuna Sung, PHD Senior Principal Scientist, Cancer Surveillance Research American Cancer Society Kennesaw, GA 30144
  MedicalResearch.com: What is the background for this study? Response: Triple-negative breast cancer (TNBC) accounts for 10% to 20% of all breast cancer diagnoses in the US. This subtype of breast cancer tends to spread faster and has fewer treatment options. In the US, Black women are about two-fold more likely than White women to develop TNBC. (more…)

MedicalResearch.com Interview with: Wendie Berg, MD, PhD, FACR Professor of Radiology University of Pittsburgh MedicalResearch.com: What is the background for this study? Response: Mammography misses many cancers in women with a personal history of breast cancer (PHBC). MRI improves early detection of cancer in women with PHBC and the American College of Radiology recommends adding MRI every year for women with PHBC and dense breasts or diagnosis by age 50 but not every woman can tolerate MRI. Contrast-enhanced mammography (CEM) appears to be a good alternative to MRI.  Our study examined performance of CEM after tomosynthesis in women with PHBC.  We first trained our radiologists in CEM (Berg WA et al JBI 2021) and two radiologists interpreted both tomosynthesis and CEM on every participant.

MedicalResearch.com Interview with: Dr. Amy Kirkham, PhD Assistant Professor of Clinical Cardiovascular Health Faculty of Kinesiology & Physical Education University of Toronto Affiliate Scientist at Toronto Rehabilitation Institute MedicalResearch.com:  What is the background for this study?  Response: Women who have had a breast cancer diagnosis are at least two-fold and often higher risk of cardiovascular or heart disease compared to women without a history of breast cancer. Older age, higher body mass index, and receipt of chemotherapy treatment that can injure the heart are risk factors for cardiovascular death after a breast cancer diagnosis. Time-restricted eating is a type of intermittent fasting that appears to be easy to follow and to improve some measures of metabolic health but has not been studied in populations with a cancer history. Time-restricted eating simply involves consuming all calorie intake within a specific time window, commonly 8 hours, like between 12 and 8 pm, and then only consuming water or black coffee outside of those hours. We enrolled breast cancer survivors who were aged 60 or older, had an overweight or obese mass index, and were finished chemotherapy treatment in a single-arm trial of time-restricted eating for 8 weeks. We asked participants to restrict their calorie intake between 12 and 8 pm from Monday to Friday with no restrictions on weekend and no further instructions on what to eat. (more…)

MedicalResearch.com Interview with: Dr. Frank Vicini, MD, FACR, FASTRO Principal Investigator Radiation Oncologist at GenesisCare Member of NRG Oncology MedicalResearch.com: Would you briefly explain what is meant by DCIS? Response: DCIS stands for ductal carcinoma in situ and indicates the presence of abnormal cells inside a milk duct in one or both breasts. Sometimes referred to as Stage 0 (zero), it is considered the earliest form of breast cancer and is noninvasive. The tumor has not yet left the duct-- a passageway that transports milk from the breast lobules to the nipple-- and begun to invade the healthy tissue surrounding it. Standard treatment options for DCIS include surgery, radiation therapy and hormonal therapy. (more…)

MedicalResearch.com Interview with: Giampaolo Greco PhD MPH Assistant Professor Department of Population Health Science and Policy Icahn School of Medicine  at Mount Sinai MedicalResearch.com: What is the background for this study? Response: The motivation for our study was to understand why mortality rate from breast cancer is much higher in African American women than in White women, despite the fact that these groups have similar incidence rate of breast cancer. Metabolic syndrome, a cluster of metabolic abnormalities that includes abdominal obesity, hypertension, hyperglycemia and dyslipidemia, is more prevalent among African American women and may be a risk factor for breast cancer. Subjective social status (SSS) is the perception of individuals of their own ranking in the social hierarchy and complements other parameters of socioeconomic status, such as income and education, that are considered more objective. Socioeconomic status is associated with cardiovascular and mental health. Although objective measures of social status are associated with worse breast cancer outcomes, the relationship of SSS to breast cancer is uncertain. (more…)

  Professor Jayant S Vaidya MBBS MS DNB FRCS PhD Professor of Surgery and Oncology University College London MedicalResearch.com: What is the background for this study? What type of single dose radiation is used? Response: The new paper published in the British Journal of Cancer (go.nature.com/3yN0mzu) expands on the previously published results of the large international randomised trial (TARGIT-A trial)(BMJ 2020;370:m2836), that confirmed the long-term effectiveness of Targeted Intraoperative Radiotherapy (TARGIT-IORT): a breast cancer treatment which is increasingly available throughout the world. The TARGIT-A trial found that a single dose of targeted radiotherapy during surgery (TARGIT-IORT) is just as effective as conventional radiotherapy, which requires several visits to hospital after surgery. From the perspective of patients, it is so much better for them and also allows prompt completion of cancer treatment during the COVID pandemic. Conventional external beam radiotherapy (EBRT) is delivered from outside the body via a radiotherapy machine (linear accelerator), and consists of a daily treatment session (known as fractions) to the whole breast, over a period between three to six weeks. Each of these treatments is given over a few minutes, but requires up to 30 hospital visits, which could be a significant distance from where the patient lives. TARGIT-IORT is delivered immediately after lumpectomy (tumour removal), via a small ball-shaped device placed inside the breast, directly where the cancer had been. The single-dose treatment lasts for around 20 to 30 minutes and replaces the need for extra hospital visits, benefiting both patient safety and well-being. The device used is called INTRABEAM. The new results are described on the Nature.com and UCL webpages https://go.nature.com/3ymrplc blog https://www.ucl.ac.uk/news/2021/may/pioneering-single-dose-radiotherapy-breast-cancer-treatment and explained in a short video https://youtu.be/w0OMjVfJ5pY  (more…)

MedicalResearch.com Interview with: Ying Liu, MD, PhD Assistant Professor Washington University School of Medicine Department of Surgery, Division of Public Health Sciences St. Louis, MO MedicalResearch.com: What is the background for this study? Response: Non-Hispanic African American women experience a disproportional burden of poor breast cancer outcomes than non-Hispanic White women, which is associated with a higher incidence of triple-negative breast cancer (TNBC), more advanced stages at diagnosis, and lower treatment adherence. However, the differences in clinical treatment and outcomes between African American women with TNBC and their White counterparts have not been well defined. (more…)

MedicalResearch.com Interview with: Kelly de Ligt, PhD Postdoctoral researcher | Project lead ‘PRO implementation in clinical care’ Psycho Social Research and Epidemiology (PSOE) Netherlands Cancer Institute – Antoni van Leeuwenhoek MedicalResearch.com: What is the background for this study? Response: Health-related Quality of Life (HRQoL) and survivorship has become increasingly important within breast cancer care, as the majority of women survives at least 10 years after breast cancer diagnosis. Breast cancer survivors may experience multiple co-existing symptoms that affect their health-related quality of life (HRQoL). Previous studies have mainly studied these symptoms as separate, independent items. However in reality, survivors usually experience multiple symptoms that can add up. We therefore studied the overall symptom burden in breast cancer survivors and tried to identify patterns in this. We believe this may be more relevant, as currently the needs of breast cancer survivors are not fully met and there is a growing demand for personalized follow-up care. We selected breast cancer survivors from the Netherlands Cancer Registry, which contains comprehensive information about diagnosis and treatment for all cancer patients in the Netherlands. Women who had been surgically treated with or without adjuvant treatment for breast cancer stages I to III and between one and five years after diagnosis were invited to participate in our survey. A total of 404 participating survivors were questioned about their experienced burden for fatigue, nausea, pain, shortness of breath, insomnia, appetite, constipation, diarrhoea, as well as emotional and cognitive symptoms  (more…)
Author Interviews, Breast Cancer, Brigham & Women's - Harvard, NEJM / 22.04.2021

MedicalResearch.com Interview with: Aditya Bardia MD, MPH Director, Breast Cancer Research Program, Attending Physician, Massachusetts General Hospital Harvard Medical School  MedicalResearch.com: What is the background for this study? Response: Triple negative breast cancer (TNBC) represents an aggressive subtype of breast cancer associated with guarded prognosis. For patients with pre-treated metastatic TNBC, standard chemotherapy is associated with low response rate (5-10%) and poor progression-free survival (2-3 months), highlighting need for better therapies. Sacituzumab govitecan is an antibody drug conjugate (ADC) which  combines SN-38, an active metabolite of irinotecan, with an antibody against Trop-2, an antigen overexpressed in majority of triple negative breast cancer.
