Associations and Affiliations:

The College of Physicians and Surgeons of Ontario, Canadian Association of Radiation Oncologists, and the American Society for Radiation Oncology.

Research Focus:

Dr. Fenkell main's research focus is on Genitourinary and breast malignancies.

Research Summary of Key Projects:

Title: A Randomized Trial of a Shorter Radiation Fractionation Schedule for the Treatment of Localized Prostate Cancer (PROFIT).

Purpose: This trial is designed to determine whether an 8-week course of escalated dose conformal radiation can be compressed safely, and with similar efficacy into a 4-week course.

In April 2011, the Radiation Medicine Program at Southlake implemented Volumetric Modulated Arc Therapy (VMAT) in the treatment of patients with prostate cancer. The Stronach Cancer Centre was the first centre across the Central LHIN to utilize VMAT in the treatment of prostate cancer. Major benefits of VMAT include significantly faster and potentially more comfortable treatment.

Research Goals:

With over 1,200 patients participating internationally, the PROFIT research trial hopes to lead to a significant reduction in the duration of prostate cancer treatment and considerable benefits to patients, their families and the community.

Future Goals and Interest in Research:

Dr. Fenkell is interested in investigating novel techniques and technologies in the treatment of prostate cancer that allow for better cancer targeting and decreased side effects.
