Summary

Cancer radiotherapy waiting times in Ontario significantly increased between 1982 and 1991. Delays, particularly between consultation and treatment initiation, worsened, with few patients meeting recommended intervals by 1991.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Health Services Research

Background:

  • Radiotherapy waiting lists are a significant challenge in Canadian cancer centers.
  • Understanding the extent of these delays is crucial for improving patient care and resource allocation.

Purpose of the Study:

  • To quantify the magnitude of radiotherapy waiting times in Ontario.
  • To analyze delays in treatment initiation for specific cancer types.

Main Methods:

  • Calculated intervals between diagnosis and radiotherapy initiation for laryngeal, cervical, lung, and prostate cancers (1982-1991).
  • Assessed intervals between surgery and postoperative radiotherapy for breast cancer.
  • Analyzed delays in diagnosis-to-referral, referral-to-consultation, and consultation-to-treatment phases.

Main Results:

  • Median waiting times increased substantially for laryngeal (178.7%), cervical (105.6%), lung (158.3%), and prostate (62.9%) cancers.
  • Breast cancer postoperative radiotherapy wait times increased by 102.7%.
  • The primary source of increased delay was the consultation-to-treatment interval, with significant inter-center variations.

Conclusions:

  • Ontario cancer centers failed to meet recommended 2-week intervals for consultation-to-treatment by 1991.
  • Waiting times for radiotherapy in Ontario have demonstrably worsened over the study period.
  • Urgent improvements are needed to reduce treatment delays and adhere to established standards of care.
