Author Interviews, Cancer Research, JAMA / 06.09.2022

MedicalResearch.com Interview with: Samir Parekh, MBBS Hematology-Oncology, Cancer Director of Translational Research in Myeloma and Co-leader of the Cancer Clinical Investigation program The Tisch Cancer Institute Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings? Response: Clinical outcomes for myeloma patients patients have improved significantly over the past decade with the introduction and success of newer immunomodulatory treatments such as CART cell therapy and bispecific antibodies. Strategies are needed to determine the best treatment options for patients relapsing or unresponsive to initial courses of these types of therapies. We analyzed the outcomes of patients relapsing after bispecific antibody therapy for myeloma. Our data shows that sequencing of bispecific antibodies or CART after initial bispecific failure can effectively salvage patients and lead to excellent outcomes in myeloma. This provides the foundation for future studies combining this new class of immunotherapy with CART or additional bispecific antibodies to improve outcomes in myeloma. (more…)

MedicalResearch.com Interview with: Professor Stephen Duffy Director of the Policy Research Unit in Cancer Awareness, Screening and Early Diagnosis Centre Lead, Centre for Prevention, Detection and Diagnosis Queen Mary University of London MedicalResearch.com: What is the background for this study? Response: The NHS Bowel Cancer Screening Programme provides 2 yearly screening to men and women aged 60-74, and it is in the process of reducing the starting age to 50 years. The screening method is faecal immunochemical testing (FIT), in which the screenee places a small sample of faeces in a container and mails this back to the lab, which tests the sample for haemoglobin, as bleeding can be a sign of cancer. The screenee is invited for colonoscopy if the level of haemoglobin is higher than 120 micrograms per gram. The system is under considerable pressure as there are limited colonoscopy resources, the programme is working towards a lower age at starting screening and we are still dealing with the backlog caused by the COVID-19 pandemic, and there may be a need to reduce the intensity of screening in order that the colonoscopy services can cope.

Author Interviews, Cancer Research / 09.08.2022

MedicalResearch.com Interview with: Sarah S. Jackson PhD Infections and Immunoepidemiology Branch Division of Cancer Epidemiology and Genetics National Cancer Institute Bethesda, MD 20892 MedicalResearch.com: What is the background for this study? Response: There are many cancers that both men and women can develop, specifically those that do not affect the reproductive tract. Men have higher rates of these nonreproductive cancers than women. There are only two nonreproductive cancer types that are more common in women: thyroid and gallbladder. Historically, we have thought this is because women are less likely to smoke or drink and are more likely to eat well and exercise than men. This study sought to examine the sex bias in cancer incidence after controlling for those lifestyle factors to see if this explained the male predominance in cancer. (more…)

MedicalResearch.com Interview with: Prof. John C. Mathers PhD Director, Human Nutrition Research Centre Director, Centre for Healthier Lives Population Health Sciences Institute Newcastle University Newcastle on Tyne UK MedicalResearch.com:  What is the background for this study?   Response: My colleagues and I have had a long-term interest in carrying out studies in people with hereditary cancer as a model for cancer in the general population. Here we studied people with Lynch syndrome who have an inherited defect in one of the genes encoding the DNA mismatch repair system. Because of this, they accumulate DNA damage faster than the general population and are prone to early cancers at several sites around the body. In the CAPP2 Study, we randomised almost 1000 people with Lynch syndrome to either resistant starch or to an ordinary corn-starch placebo. (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Lung Cancer, Supplements, USPSTF / 30.06.2022

MedicalResearch.com Interview with: Michael J. Barry, M.D Director of the Informed Medical Decisions Program Health Decision Sciences Center Massachusetts General Hospital. Professor of medicine at Harvard Medical School Dr. Barry was appointed as Vice Chair of USPSTF in March 2021. He previously served as a member from January 2017 through December 2020.   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: The Task Force looked at the use of vitamin and mineral supplementation specifically for the prevention of heart disease, stroke, and cancer. We found that there is not enough evidence to recommend for or against taking multivitamin supplements, nor the use of single or paired nutrient supplements, to prevent these conditions. However, we do know that you should not take vitamin E or beta-carotene for this purpose. (more…)

MedicalResearch.com Interview with: Karla Kerlikowske, MD. Professor, Departments of Medicine and Epidemiology/Biostatistics, Cancer Center Program Membership. Breast Oncology UCSF MedicalResearch.com:  What is the background for this study?  Response: Digital breast tomosynthesis (DBT) was developed with the expectation it would improve detection of breast cancer in women with dense breasts and decrease false-positive results. DBT is now available at most breast screening centers. (more…)
Author Interviews, Cancer Research, JAMA, Race/Ethnic Diversity / 10.06.2022

MedicalResearch.com Interview with: Marquita W. Lewis-Thames, PhD (she/her/Dr.) Assistant Professor, Department of Medical Social Science Center for Community Health, Member Researcher Assistant Directors of Community Outreach and Engagement, Robert H. Lurie Comprehensive Cancer Center Feinberg School of Medicine, Northwestern University MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: Incidence, mortality, and survivorship provide a comprehensive description of cancer for a group of people. Differences in cancer incidence and mortality trends by rural-urban status and race and ethnicity are well documented, but urban-rural cancer survivorship trends by race and ethnicity are unknown. To this end, we examined almost 40 years of racial and ethnic differences by rural-urban status for 5-year survival of patients with lung, prostate, breast, and colorectal cancers. Using a nationwide epidemiological assessment of 1975-2011 data from the SEER database, we found that 5-year cancer-specific survival trends increased for all cancer types and race and ethnic groups, regardless of rural or urban status. Generally, rural, and non-Hispanic Black cancer patients had worse survival outcomes than others. (more…)

MedicalResearch.com Interview with: Sachi Singhal, MD Department of Medicine Crozer Chester Medical Center Upland, PA MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: This study focuses on analysing the National Inpatient Sample for patients with breast cancer, their breakdown by race, gender and US regions, and their mortality per sub-group. The main findings are that African Americans, especially AA women are at significantly increased odds of dying from metastatic breast cancer in the United States. (more…)
ASCO, Author Interviews, Cancer Research, COVID -19 Coronavirus, NYU / 08.06.2022

MedicalResearch.com Interview with: Katherine Garcia MD NYU Langone Health MedicalResearch.com:  What is the background for this study?  Response: Studies on cancer patients during the COVID-19 pandemic have shown a decrease in new diagnoses, delays in care, and a shift to later stage disease presentations. Considering that NY has been an epicenter for COVID-19 in the U.S., we investigated its impact on new cancer diagnoses at the two campuses of NYU’s Perlmutter Cancer Center and hypothesized that there would be a decrease in presentations during the peak outbreaks in NY.

Author Interviews, Cancer Research, Nature, Pancreatic, University of Michigan / 03.06.2022

MedicalResearch.com Interview with: Imad Shureiqi, MD, MS Professor, Division of Hematology and Oncology Department of Internal Medicine Rogel Cancer Center Ann Arbor, MI, 48109 MedicalResearch.com:  What is the background for this study?   Response: Pancreatic ductal adenocarcinoma is a highly lethal form of cancer with rising occurrence, and strategies to prevent and treat the disease are urgently needed. Most cases of pancreatic cancer arise from pre-cancerous lesions called pancreatic intraepithelial neoplasia (PanIN); about 55-80% of adults over forty are estimated to have these low-grade pre-cancerous silent pancreatic lesions. But critical factors that promote the progression of pancreatic pre-cancerous lesions to pancreatic cancer remain poorly defined, especially those easy to target. Findings from this publication indicate that people who have silent PanIN pre-cancerous lesions, even those that are low-grade, could increase their risk of PanIN progression into pancreatic cancer by consuming activators of a nuclear lipid receptor called peroxisome proliferator-activated receptor-delta (PPARδ). PPARδ activators can be natural substances, such certain fatty acids like palmitic and arachidonic acid in high-fat diets, or synthetic ones, like Cardarine (GW501516). (more…)
Author Interviews, Cancer Research, Gastrointestinal Disease / 20.05.2022

MedicalResearch.com Interview with: Bashar J. Qumseya, MD, MPH, FASGE Associate Professor of Medicine Chief of Endoscopy University of Florida, Gainesville  MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Barrett’s esophagus (BE), is a premalignant condition that can lead to esophageal cancer (called esophageal adenocarcinoma). Both diseases have historically been thought of as diseases of elderly white males. While both diseases have been on the rise in the elderly population, we noted that some cancers are becoming more common at younger ages. We wanted to see if the prevalence of BE and EC are increasing at younger ages.  We aimed to assess the prevalence of BE in and EAC based on age group in a large database of over 5 million patients.  (more…)
Author Interviews, Cancer Research, Pharmaceutical Companies / 20.05.2022

MedicalResearch.com Interview with: Robert Wild, Ph.D Chief Scientific Officer Dracen Pharmaceuticals   MedicalResearch.com:  What is the background for the development of sirpiglenastat, i.e., would you briefly explain what is meant by glutamine antagonist? Response: Cancer cells consume and use glutamine for both energy generation and as a source of carbon and nitrogen for biomass accumulation. Many oncogenes and tumor suppressor genes drive large-scale metabolic reprogramming of tumors into glutamine addiction. These highly proliferating tumors create a hostile and immunosuppressive tumor microenvironment (TME), which is nutrient- depleted, acidic and hypoxic in nature. Sirpiglenastat (DRP-104), is a novel broad-acting glutamine antagonist that inhibits all 10 known glutamine metabolism enzymes. DRP-104 was designed to preferentially inhibit glutamine metabolism in tumors and associated TME and not in normal tissues, providing a large therapeutic window. DRP-104 demonstrates powerful direct apoptotic (cell death) properties and immune modulatory mechanisms through broad remodeling of the TME to infer DRP-104 impacts immune-metabolism. Inhibition of glutamine metabolism leads to:
  • Induction of apoptosis in glutamine-addicted tumor cells leading to substantial single-agent activity and tumor regressions
  • Rebalance of the TME that enhances immune cell infiltration and function
  • Differentiation and modulation of adaptive and innate immune cells toward a highly proliferative, activated and long-lived phenotype for a long-term durable response.

Author Interviews, Biomarkers, Cancer Research, Hepatitis - Liver Disease / 18.05.2022

MedicalResearch.com Interview with: Yujin Hoshida, MD, PhD Director, Liver Tumor Translational Research Program CPRIT Scholar in Cancer Research Harold C. Simmons Comprehensive Cancer Center Professor of Internal Medicine Division of Digestive and Liver Diseases, Department of Internal Medicine University of Texas Southwestern Medical Center MedicalResearch.com:  What is the background for this study?  Response: Liver cancer is the fastest rising cause of cancer-related death in the U.S. with the sharply growing epidemic of obesity and non-alcoholic fatty liver disease. Late diagnosis at advanced stage is the main reason for the poor survival of liver cancer patients. Therefore, professional societies recommend semi-annual liver cancer screening for early diagnosis. However, it's practically infeasible due to the vast size of patient population (estimated to affect one-fourth of population). Thus, we urgently need tools to identify a small subset of patients with elevated liver cancer risk, on which we can concentrate our effort of screening. (more…)

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…)
Author Interviews, Biomarkers, Cancer Research, Colon Cancer / 18.05.2022

MedicalResearch.com Interview with: AmirAli Talasaz Ph.D. co-CEO, Guardant Health MedicalResearch.com:  What is the background for this announcement? Response: On May 2, Guardant Health announced the availability of Shield™, our first blood-based test for the detection of early-stage colorectal cancer (CRC). Colorectal cancer is the second-leading cause of cancer deaths in the U.S., so this announcement represents a tremendous public health opportunity. Here’s why: This new test will help people identify more CRC at its earliest stages, when it is most treatable. It offers an accurate, easy-to-complete, blood-based approach to CRC screening. It can be completed with a convenient blood draw during any healthcare provider visit.  (more…)

MedicalResearch.com Interview with: Megan Clarke, Ph.D., M.H.S., Earl Stadtman Investigator Division of Cancer Epidemiology and Genetics National Cancer Institute MedicalResearch.com:  What is the background for this study? 
  • Through our prior work, we have demonstrated that uterine cancer incidence rates have been significantly increasing in the U.S. from 2003 to 2015 and that these increases were primarily driven by rising rates of aggressive (non-endometrioid) subtypes of this cancer. We observed that rates of these aggressive cancers increased among all women and were more than twice as high among Non-Hispanic Black women compared to other racial and ethnic groups. Factors explaining these trends, as well as the disproportionately higher rates of these aggressive subtypes among non-Hispanic Black women, remain unclear, in part because risk factors are poorly understood.
  • In addition to differences in incidence rates by race and ethnicity, we have also observed strong disparities in our prior studies, with Non-Hispanic Black women having substantially lower 5-year survival, regardless of subtype or stage at diagnosis, compared to other racial and ethnic populations.
  • The next logical step, and the focus of the current study, was to evaluate how increases in the incidence of aggressive, non-endometrioid uterine cancer affects racial disparities and rates of death from uterine cancer.

MedicalResearch.com Interview with: Leticia NogueiraPhDMPH Senior Principal Scientist, Health Services Research American Cancer Society, Inc. Kennesaw, GA 30144 MedicalResearch.com:  What is the background for this study?  Response: Proton Beam Therapy (PBT) can deliver higher dose of radiation to the tumor with less damage to surrounding healthy cells. Therefore, PBT is potentially superior to photon-based radiation therapy to treat tumors with complex anatomy, surrounded by sensitive tissues, or for treating childhood cancer (where long-term side effects of radiation therapy are a main concern). However, PBT can cost twice as much as photon-based radiation therapy.  (more…)
Author Interviews, Breast Cancer, Cancer Research, Race/Ethnic Diversity, Vitamin D / 26.04.2022

MedicalResearch.com Interview with: Katie M. O’Brien PhD Chronic Disease Epidemiology Group National Institute of Environmental Health Sciences MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Vitamin D may protect against breast cancer. Although women of color have lower average vitamin D levels than non-Hispanic White women, few studies have considered the role of race/ethnicity. In a sample of self-identified Black/African American and Hispanic/Latina women, we observed that vitamin D concentrations measured in blood were inversely associated with breast cancer, particularly among Latinas. These findings indicate that vitamin D may protect against breast cancer, including among racial/ethnic groups with low average circulating levels. (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, Genetic Research, Nature / 18.04.2022

MedicalResearch.com Interview with: Jason Vassy, MD, MPH Brigham and Women's Hospital Division of General Internal Medicine & Primary Care Brigham’s Precision Population Health at Ariadne Labs and VA Boston  MedicalResearch.com:  What is the background for this study?    Response: A person’s risk of developing diseases such as type 2 diabetes or breast cancer may be influenced by thousands of genetic differences, the effects of which can be combined to derive a single score, often called a polygenic risk score (PRS). PRS might be useful to help patients and their physicians make tailored decisions about their health care, but several challenges to the clinical implementation of PRS remain. Most importantly, most PRS are less accurate in individuals of non-European descent, since most genomic research to date has been conducted in European populations. Another key challenge is that physicians and patients will need support to understand polygenic risk score and use them to make medical decisions. Clinical guidelines do not yet exist to help a physician know whether and how they should treat a patient with a high-risk score differently than an average-risk patient. We designed the Genomic Medicine at VA (GenoVA) Study to address some of these challenges. (more…)

MedicalResearch.com Interview with: Ajit Johnson Nirmal PhD Instructor of Medicine, DFCI, HMS Laboratory of systems pharmacology Harvard Medical School MedicalResearch.com:  What is the background for this study?  Response: Like many other types of cancers, melanoma arises from gene mutations within cells that impact cell growth and division. These abnormal cells should be rapidly eliminated by our immune system, however, the failure to do so leads to the development of cancer. Hence researchers have long been interested to study the tumor environment that nurtures and sustains these dangerous cells. In the past, researchers have used single-cell technologies to delineate the cell types and cell states that make up the tumor microenvironment. However, the spatial relationships between these cell types and how they organize themselves such as to provide a favorable environment for the tumor to develop remains unknown. In the last couple of years, researchers have developed a new suite of new technologies called spatial omics which includes CYCIF a method that was developed at Sorger lab. Using this method, we can not only measure the molecular information of cells at a single cell level but also their spatial context. This allows us to build a google map like view of the skin with melanoma and study what is exactly happening that allows the tumors to develop. (more…)
Author Interviews, Cancer Research, Clots - Coagulation / 18.04.2022

MedicalResearch.com Interview with: Dr. med. univ. Cornelia Englisch Medical University of Vienna MedicalResearch.com:  What is the background for this study?  Response: Patients with cancer are at high risk for developing venous thromboembolism (VTE). Venous thromboembolism includes deep vein thrombosis (DVT), when blood clots form in the deep veins of the legs and pulmonary embolism (PE), a potential life-threatening condition when a clot breaks free and lodges in the arteries of the lung. Having a non-O blood type, meaning blood types A, AB or B, is a known risk factor for VTE in the general – non-cancer – population. Interestingly, it is the most common genetic risk factor for thrombosis. If this is also the case in patients with cancer has not been clarified yet. We therefore wanted to assess the role of ABO blood type in cancer-associated thrombosis. To achieve our goal, we utilized the dataset of the Vienna Cancer and Thrombosis Study (CATS); an observational cohort study including adult patients with active cancer. (more…)
Author Interviews, Dermatology, JAMA, Melanoma, University of Pittsburgh / 08.04.2022

MedicalResearch.com Interview with: Laura Ferris, M.D., Ph.D. Professor of Dermatology Director of clinical trials for UPMC Department of Dermatology University of Pittsburgh School of Medicine MedicalResearch.com:  What is the background for this study?  Response: In this quality initiative at UPMC (a large academic and community health system in Western PA and surrounding areas) Primary Care Physicians were trained to perform annual skin cancer screening examinations of their patients who were aged 35 years and older at routine medical visits. Over a 5-year period more than 595,000 patients who were eligible to be screened were seen by a UPMC PCP and about 24% of them were screened. We compared the number and thickness (an important indicator of prognosis) of the melanomas diagnosed in those patients who were screened to those who were not screened. (more…)

MedicalResearch.com Interview with: Howard D. Sesso, ScD, MPH Associate Professor of Medicine Division of Preventive Medicine Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study? How does the amount of flavanols in the study arm compare to what might be obtained in a typical diet? Response: The COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is a randomized, double-blind, placebo-controlled clinical trial that tested the effects of two promising dietary supplements on cardiovascular disease (CVD) and cancer in 21,442 older adults. Cocoa flavanols have been shown to have favorable vascular effects in small and short-term clinical trials. The 500 mg/day flavanols tested in COSMOS exceeds that readily obtained in the diet typically from cocoa, tea, grapes, and berries. Of note, flavanol content in not typically listed on food labels. COSMOS also tested a multivitamin, the most common dietary supplement taken by US adults and previously linked with a potential modest reduction in cancer in a previous long-term trial of men conducted by our research group at the Division of Preventive Medicine at Brigham and Women’s Hospital.

Author Interviews, Biomarkers, BMJ, Gastrointestinal Disease, Pancreatic / 09.03.2022

MedicalResearch.com Interview with: Ece Kartal, PhD Postdoctoral Fellow Saez-Rodriguez Group Universitätsklinikum Heidelberg Institute for Computational Biomedicine Heidelberg MedicalResearch.com:  What is the background for this study?    Response: Pancreatic cancer is one of the deadliest types of cancer: although incidence rates are relatively low (only few people develop pancreatic cancer in their lifetimes), it has a high lethality, with a five year survival rate of less than ~5%. Pancreatic cancer symptoms are generally unspecific so that the disease is usually detected very late which further  limits therapeutic options. In light of this, earlier detection of pancreatic cancer could dramatically improve prognosis, but there are currently no affordable and non-invasive tests available in the clinic. For pancreatic ductal adenocarcinoma (PDAC),the most common form of pancreatic cancer, it was previously found that the oral, gut and pancreatic microbiome are risk factors and may affect prognosis .

MedicalResearch.com Interview with: Dr. Saundra Singh M.D., Ph.D. Founder & CEO/President Singh Biotechnology https://www.singhbiotechnology.com/       MedicalResearch.com: What is the mission of Singh Biotechnology?  
  • Our mission is to develop medicine and therapeutics that dramatically improve and save the lives of people worldwide suffering from diseases, including cancer.
MedicalResearch.com: What are the advantages of the Single Domain Antibody technology?
  • The average human antibody is 150 Kd in size and works on the outside of the cell. The advantage of the single domain nanobody is that it is significantly smaller, in fact, it is one-tenth the size (approximately 15 Kd) of the human antibody. A smaller nanobody is more useful therapeutically because, unlike many cancer drugs currently on the market, it can penetrate the blood-brain barrier, the blood-retina barrier, and the cell membrane. Moreover, our SBT-100 drug has been shown to be non-toxic in animal models.

MedicalResearch.com Interview with: Dr Rana Conway PhD RNutr  Research Fellow Energy Balance & Cancer Group, and Obesity Research Group Research Department of Behavioural Science and Health University College London    MedicalResearch.com: What is the background for this study? Response: We’ve seen great advances in cancer diagnosis and treatment in recent years which means the number of people living with and beyond a cancer diagnosis is rapidly increasing. The WCRF and CRUK recommend improving diet and exercise to reduce the risks of cancer coming back but we know anecdotally that supplements are sometimes seen as an easier option, and people who’ve had cancer are often interested to know if they should be taking any supplements.    (more…)

MedicalResearch.com Interview with: Ting Martin Ma, MD, PhD Resident Physician Amar U. Kishan, MD Assistant Professor, Department of Radiation Oncology Vice-Chair of Clinical and Translational Research Department of Radiation Oncology at UCLA MedicalResearch.com: What is the background for this study? Response: We know from epidemiologic studies that  Black men are more likely to be diagnosed with and die of prostate cancer than White men. Recent studies hinted that Black men had better oncological outcome (such as prostate cancer specific mortality and overall survival) responding to systemic therapy for advanced prostate cancer (e.g. cancer that has spread or metastasized to other parts of the body). The question we were trying to answer in this study is: is there a difference in outcomes between Black and White men with localized prostate cancer (cancer that has not spread) receiving definitive radiotherapy enrolled in clinical trials?  (more…)

MedicalResearch.com Interview with: Ashish A. Deshmukh, PhD, MPH Associate Professor, Management, Policy & Community Health Associate Director, Center for Health Services Research Co-director, Clinical Analytics and Decision Science Lab UTHealth School of Public Health Houston, TX 77030 MedicalResearch.com: What is the background for this study? Response: Oropharyngeal cancer is the most common cancer caused by human papillomavirus (HPV) in the United States (US). We know from previous studies that oropharyngeal cancer to be one of the fastest rising cancers in the US. However, trends (i.e., extent of change) in incidence rates among men and women in all 50 US states and trends according to tumor diagnostic characteristics (i.e., stage, size) have not been comprehensively studied. In addition, no prior study evaluated contemporary trends in oropharyngeal cancer mortality (death) rates in the US. Our study provides a comprehensive picture of oropharyngeal cancer incidence and mortality (according to age, stage, tumor size, and state of residence) in all 50 states and DC. (more…)
Author Interviews, Cancer Research, Dermatology, Lancet, Melanoma, Technology / 11.11.2021

MedicalResearch.com Interview with: Dr David Wen BM BCh NIHR Academic Clinical Fellow in Dermatology University of Oxford MedicalResearch.com: What is the background for this study? Response: Publicly available skin image datasets are commonly used to develop machine learning (ML) algorithms for skin cancer diagnosis. These datasets are often utilised as they circumvent many of the barriers associated with large scale skin lesion image acquisition. Furthermore, publicly available datasets can be used as a benchmark for direct comparison of algorithm performance. Dataset and image metadata provide information about the disease and population upon which the algorithm was trained or validated on. This is important to know because machine learning algorithms heavily depend on the data used to train them; algorithms used for skin lesion classification frequently underperform when tested on independent datasets to which they were trained on. Detailing dataset composition is essential for extrapolating assumptions of generalisability of algorithm performance to other populations. At the time this review was conducted, the total number of publicly available datasets globally and their respective content had not previously been characterised. Therefore, we aimed to identify publicly available skin image datasets used to develop ML algorithms for skin cancer diagnosis, to categorise their data access requirements, and to systematically evaluate their characteristics including associated metadata.   (more…)
