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.
