Workshop Report: A Practical Approach and General Principles of Re-irradiation for In-field Cancer Recurrence

In-field cancer recurrence after previous adjuvant or radical radiotherapy presents particularly challenging clinical issues to the oncologists. A Canadian pattern of practice survey showed a wide range of approaches in treatment intent, planning and dose fractionation. A workshop on re-irradiation was conducted at the 2009 Canadian Association of Radiation Oncology annual scientific meeting, under the guidance of the Symptom Control Committee, in an effort to promote a uniform approach among radiation oncologists in their approach to re-irradiation. The workshop has made various recommendations in an effort to bring consistency among radiation oncologists across Canada to their approach towards re-irradiation.
