Research Summary:

The focus of Dr. Szumacher's research is to understand the needs and preferences of cancer patients in radiation oncology practice. This includes:

  • understanding patient preferences in the treatment of bone metastases with palliative radiotherapy (RT)
  • understanding needs of older patients with early breast cancer while undergoing adjuvant RT
  • developing a patient decision aid for adjuvant RT for older women with early breast cancer
  • understanding the needs of prostate cancer patients treated with radical prostatectomy who require adjuvant and salvage RT.

Dr. Szumacher aims to improve the care of cancer patients by working together as an interprofessional team in radiation oncology practice. This is achieved by:

  • fostering an interprofessional practice in radiation oncology through continuing medical education (CME), scholarly work and research
  • understanding the needs of health care providers in cancer care and enhancing RT services and treatment in underserviced areas
  • developing and assessing the effectiveness of an educational intervention on the congruence of prostate and rectal contouring as compared to a gold standard in planning for three-dimensional RT for prostate cancer
  • developing an interprofessional learning environment and creating modalities for continuing professional education in radiation therapy by organizing interprofessional CME events 
  • investigating interprofessional needs of cancer care providers and trainees.
