  1. Carrie Featherstone Consultant Clinical Oncologist Feb 2009

  2. Radiotherapy • Models for Radiotherapy Rates: • What the models are • Network data for models • Breast, lung, head and neck rates • Remodelling Prostate • Other • Network Cancer Incidence Numbers • Fractionation

  3. Breast staging across Scotland Different methods of data collection by networks: not specific for these models

  4. Breast Model based on Lothian data Total patients receiving XRT = 3354 = 80% PTS NEED RT Actual XRT utilisation in SCAN 2006 = 69% (low grade DCIS +WLE not currently treated)

  5. Breast Model based on Grampian data Total patients receiving XRT = 2632 = 63% ORR. Actual XRT utilisation Grampian 2007= 57%

  6. New Prostate model

  7. Breast Grampian 63% v 57% SCAN 79% v 69% Lung SCAN 64.2(50%) v 40 Head and Neck 83%v70% Prostate 61 (28%) Other where queries in optimal rates due to British practice Oesophagus 10% Stomach 5% Pancreas 5% Melanoma 5% Optimal v Actual Radiotherapy Rates

  8. Future Needs The number of radiotherapy courses per 1,000 cancers is a good indicator of access to radiotherapy. The range varied from 308 to 823 with an average of 562 radiotherapy courses per 1,000 cancers.

  9. NRAG Max ?8 9.2 hours 4-4.5 3-8 2 hours Ave 19days 234-239days >8000 per machine Total193,844# (175,954# in 2003)

  10. Other Methods Machines/Fractions per million 18% increase in cacncer incidence in 10 years No of fraction increase 2003 to 2008

  11. Machine requirement • Linac Output: Fractions per hour • Hours per day • Days per week • Days per year (servicing etc) • Size of dept • QA/research • Service efficiency per Linac
