As a cancer epidemiologist, Dr. Sarah C. Markt focuses on integrating molecular, lifestyle, and clinical epidemiology to study risk factors for initiation and progression of genitourinary cancers, with the goal of translating findings into cancer prevention. Her work encompasses a number of studies including research on circadian rhythm disruption as a risk factor for prostate cancer, and the effects of a physical activity intervention on men with prostate cancer. She also is researching the clinical utility of using tumor genomic markers for genitourinary cancers. In addition to this work, she directs the disease follow-up of men with bladder cancer in a 50,000 subject longitudinal cohort study. Finally, she co-directs a testicular cancer patient database at the Dana-Farber Cancer Institute (DFCI).  In addition to her own research, she serves as a research mentor to undergraduate and graduate students, and clinical fellows.

Research Interests

My research involves integrating molecular, lifestyle and clinical epidemiology to study risk factors for initiation and progression of cancer, with the primary goal to translate research findings into direct application for primary and secondary cancer prevention. A major area of my research focus is in investigating circadian rhythm disruption as a risk factor for cancer, and particularly for risk of advanced prostate cancer. I am also interested in understanding the molecular basis for tumor progression and the clinical utility of utilizing genomic markers for cancer outcomes, with a particular focus on prostate, testicular and bladder cancer. Another area of my research focus is in developing lifestyle interventions (e.g. physical activity) to enhance the efficacy of therapeutic interventions, ameliorate treatment-related effects, and improve overall health and quality of life among cancer patients.

Additional Information

Contributions to science:

  • Investigated the role of a urinary biomarker (melatonin), genetic variation and questionnaire data on sleep duration and disruption in prostate cancer risk and progression. 
  • Through collaboration, investigated genetic variation and aggressive prostate cancer risk utilizing a candidate gene approach. Also found single nucleotide polymorphisms in circadian related genes were associated with risk or fatal prostate cancer. 
  • Investigated modifiable lifestyle factors in early-, mid-, and later-life, for risk of advanced and lethal prostate cancers using cohorts nationally and internationally.
  • Investigated through collaboration risk factors for progression of testicular germ cell tumors using a clinical testicular cancer patient database and publicly available datasets, including evaluating health disparities among this young patient population.
