Essential services for cancer
• Diagnostic – Pathology – Labs – Imaging
• Surgery • Radiotherapy • Chemotherapy • Palliative care
IAEA
Radiotherapy Comprehensive approach
• Radiotherapy is an essential component of
effective cancer care and provides sound motivation for investment.
• Multidisciplinary approach required. Use of
technologies and skilled personnel across disciplines using radiotherapy.
IAEA
Current Radiotherapy Coverage
Current coverage of radiotherapy services according to country as determined by global equipment databases, an activity-based operations model, cancer incidence, and evidenced-
based estimates of radiotherapy need. Lancet commission Report
2012: 14.2 million new cancer cases 8 million cancer deaths
* Projected :Ferlay J et al Sources, methods and major patterns in GLOBOCAN 2012. 2015; 136(5):E359-E386.
2030 : 24.6 million new cancer cases 13 million cancer deaths*

Radiation Therapy Treatments
• Radiotherapy has been used for curative or palliative treatment of cancer, alone or combined with chemotherapy or surgery.
Robotic Body Radiosurgery
External Beam 3-D/IMRT
Gamma-knife Radiosurgery
Brachytherapy

Weakest Link
Some of the steps in radiotherapy that can be represented by links in a chain; treatment accuracy will be limited by the weakest link in the chain

Local Control and Survival Benefit from Radiation
Top 10 cancers globally by incidence: Radiotherapy utilization rate, average RT fractions and outcome benefits
(absolute proportional)**
17
The world population benefit : 10% for local control 4% for overall survival.
Cancer imposes large economic burden on countries, estimated worldwide at US$2 trillion in 2010*
*Bloom DE et al Geneva: World Economic Forum, 2011 ** personal communication Lancet Commission Report
2012: 1.5 million people local control benefit > 580,000 people survival benefit
2035: 2.5 million people local control benefit 950,000 people survival benefit

Radiation Therapy-what do we need?
People eg RO, RTT, MP, RS, Engineers Support services/technologies Maintenance Infrastructure eg electricity Quality and safety Other Disciplines eg pathology, medical
oncology infrastructure, surgery

•AFRONET network was established in June 2012 with the purpose of strengthening the process of clinical decision making in radiotherapy centers in Anglophone Africa.
•AFRONET was conceived to facilitate interactions among cancer specialists, and engage them in evidence-based cancer interventions
•Educational Virtual Tumor Boards and Lectures in relevant topics
IAEA
• Radiation oncologists from LMIC: hands-on IAEA training in 3-D radiotherapy tools • Facilitate 2D to 3D and also transition to IMRT • Plans: expand contouring training through e-Learning platform worldwide
IAEA GLOBAL COLLABORATION IN EDUCATION
TRAINING IN CONTOURING
• Research project to measure the impact of training in contouring
• Increase homogeneity among countries in contouring • Long term benefit and build new research on top

CERVICAL CANCER CONTROL
9 of 10 deaths of all cervical cancer cases occur in in less developed regions of the world Every 10th case of cancer in LMIC is cervical cancer Mortality varies 18-fold between the different regions of the world
Cancer of the uterine cervix, one of the most common female cancers
A major cause: Human papilloma virus (HPV) infection
IAEA

RESEARCH
Section No of CRPs ARBR 13 NMDI 10
NAHRES 8 DMRP 6
Background Axial image-based brachytherapy treatment planning is becoming the most accurate and reliable approach. However, it currently relies on MRI/open-MRI technology Scientific question (tentative) Can ultra-sound based treatment planning replace MRI in the brachytherapy planning of cervical cancer? Benefit to MS If US-based can be proven equivalent to MRI, then a much resource economic method can be developed and recommended to RT centres.

Questions
• How is radiotherapy cost-effective given the significant upfront cost of radiotherapy equipment ?
• How can international organizations like the IAEA help increase technology transfer in radiotherapy to contribute to achieving target 3.4 of the SDG
• What are some of the challenges in the development and access to radiation therapy and radiodiagnostic technologies for cancer diagnosis and treatment to developing countries,?
