Sigrid V. Carlsson, MD, PhD, MPH, is Director of Clinical Research at Memorial Sloan Kettering Cancer Center’s (MSKCC) Josie Robertson Surgery Center and Assistant Attending Epidemiologist, with dual appointments in MSKCC’s Departments of Surgery (Urology Service) and Epidemiology and Biostatistics. Her line of research focuses on screening and early detection of prostate cancer, including multiplex testing and risk-stratified strategies that incorporate clinical information, biomarkers and magnetic resonance imaging, as recently funded by an NIH/NCI U01 award (PI: Carlsson).

Dr. Carlsson also serves as Associate Professor of Experimental Urology affiliated with the Institute of Clinical Sciences, Sahlgrenska Academy, Gothenburg University, in Sweden, where she is an investigator of two large randomized controlled trials of prostate cancer screening (GOTEBORG-1&2), as recently published in the New England Journal of Medicine (Hugosson J, et al. N Engl J Med 2022). In addition, Dr. Carlsson is Adjunct Senior Lecturer in the Department of Translational Medicine in the Division of Urological Cancers in the Medical Faculty at Lund University, Lund, Sweden.

Dr. Carlsson recently completed a K22 career development award from the NIH/NCI to improve shared decision-making for breast and prostate cancer screening. She serves on the National Comprehensive Cancer Network (NCCN) and is a panel member for the American Urological Association (AUA) guidelines for early detection of prostate cancer. Before pursuing postdoctoral studies in urologic oncology at MSKCC, Dr. Carlsson was a physician in Sweden. She earned her MD and PhD from Gothenburg University in Sweden and earned an MPH from Harvard TH Chan School of Public Health in Boston, Massachusetts.

Who Needs a Prostate Biopsy? Risk-stratification Strategies Before Prostate Biopsy

Sigrid V. Carlsson, MD, PhD, MPH, discusses the evolving paradigm in prostate cancer diagnostics, moving away from the traditional model where an elevated prostate-specific antigen (PSA) level directly leads to a biopsy. In this 8-minute talk, she emphasizes the importance of incorporating risk stratification methods before proceeding to biopsy, which helps reduce unnecessary interventions.

Dr. Carlsson discusses current guidelines that recommend using MRI as part of the initial biopsy strategy, with a more mandatory role in repeat biopsy settings if it has not previously been performed. Risk calculators provide a cost-effective and accessible means to estimate the likelihood of high-grade disease, further refining the decision-making process.

The presentation also highlights the rapid advancement in biomarkers and the integration of artificial intelligence (AI) in improving MRI interpretation and enhancing prostate cancer diagnostics’ accuracy and efficiency.

Year in Review: Emerging Data and Advances in Prostate Cancer Screening

Sigrid V. Carlsson, MD, PhD, MPH, presents an overview of advances and emerging trends in prostate cancer screening in 2023. Dr. Carlson begins by presenting data supporting the continued use of routine PSA tests for prostate cancer screening, while highlighting the need for more granular risk stratification based on individual PSA baselines to bridge existing mortality gaps based on individual PSA baselines.

Dr. Carlsson then examines current trends in using genetics for biopsy risk stratification. She presents evidence that the polygenic risk scores which predict prostate cancer incidence are not useful in predicting mortality. She then discusses the role of biomarkers, risk calculators, and MRI-based screening techniques that are available pre-biopsy.

Turning to emerging data, Dr. Carlsson concludes by presenting a selection of national and international ongoing efforts to develop risk-stratified algorithms for early prostate cancer detection. She touches on the European Union’s “Praise U” initiative, Germany’s “PROBASE” trial, the Stockholm 3 trial, and the ProScreen study.

Screening and Prevention of Prostate Cancer 2021 (Part 3): Incorporating MRI for Early Detection

In the final part of a 3-part series, Sigrid V. Carlsson, MD, PhD, MPH, Assistant Attending Epidemiologist at Memorial Sloan Kettering Cancer Center, considers the current role of MRI in early detection of prostate cancer. She explains that while MRI is a useful screening tool, it is not foolproof, and its accuracy varies widely depending on user expertise. For this reason, using a negative MRI to justify not getting a biopsy is not always strongly advised. However, many studies are underway that may identify combinations of MRI and biomarker tests that will ultimately help patients avoid more unnecessary biopsies.

Screening and Prevention of Prostate Cancer 2021 (Part 2): Who Needs a Biopsy?

In part 2 of a 3-part series, Sigrid V. Carlsson, MD, PhD, MPH, Assistant Attending Epidemiologist at Memorial Sloan Kettering Cancer Center, goes over her 5 Golden Rules for prostate cancer testing, which are intended to minimize overdiagnosis and overtreatment while also making sure that significant disease is not missed. Rule 1 is to get consent and engage in shared decision-making with patients. Dr. Carlsson notes that this can sometimes be difficult since the numerous decision aids available are often difficult to use and understand. The second rule is not to screen men who will not benefit, for instance, older men with multiple comorbidities and short life expectancies. Dr. Carlsson does observe, however, that instituting an age cutoff does not necessarily make sense, and that physiologic assessment of life expectancy may be a more useful metric. In rule 3, Dr. Carlsson advises clinicians not to biopsy patients without a compelling reason, since prostate biopsies may lead to infectious complications and hospitalization. She then lays out the options for risk stratification, such as risk calculators, biomarker tests, and MRI. Rule 4 recommends against treating low-risk disease since, as Dr. Carlsson explains, active surveillance is a safe strategy over longer follow-up for appropriately selected patients with Grade Group 1 prostate cancer when following a well-defined monitoring plan. Finally, rule 5 exhorts clinicians to send patients who require treatment to a high-volume provider. This is key, Dr. Carlsson argues, since evidence shows that there is a large degree of heterogeneity among surgeons regarding functional and oncological outcomes after prostatectomy, and it takes approximately 250 surgeries for a surgeon to really master the procedure.
