This fourth revised edition of “Technical Basis of Radiation Therapy: Practical Clinical
Applications”, edited by S. H. Levitt, J. A. Purdy, C. A. Perez, and S. Vijaykumar, continues
this publication’s outstanding excellence in the definition of the technical advances for
radiation therapy. The previous three editions were milestones in the definition of new
technologies and how they would be applied in clinical practice.

In the 1960s radiation therapy was considered an empirical, clinical discipline with a
relatively low probability of success. This situation has changed considerably during the
past 40 years.
Radiation therapy is based heavily on fields such as physics, mathematics, computer
science and radiation biology as well as electrical and mechanical engineering, making it
a truly interdisciplinary field, unparalleled by any other clinical discipline. Now radiation
therapy can be applied so safely, precisely and efficiently that the previously feared side
effects no longer play a role.
This chapter in cell death. will focus on non-surgical approaches namely radio- therapy, chemotherapy and hormonal therapy. There are limited facilities for radiotherapy as duction of free radicals cal personnel to plan treatment and operate these and break chemical bonds thus causing cell damage radiotherapy facilities in many of the less-resourced costly for many less-resourced locations.
Science of brachytherapy is currently increasing in the field of cancer therapy. By
virtue of the development of computer assisted technologies, we can reap the benefits
of accurate radiotherapies more than ever, which enabled precise irradiation to a
target safely avoiding unnecessary involvement of the surrounding normal tissue.
Unlike teleradiotherapy provided by X-ray linear accelerator, brachytherapy utilizes
radiation source placing inside or close to the target.
CONFORMAL AND INTENSITY-MODULATED RADIOTHERAPY—WHY
Whilst drug development plays an important but expensive role in the treatment
of some cancers, it is estimated that, at a time when 2% of patients are cured
by drugs, some 30% are cured by a combination of surgery and radiotherapy.
Radiotherapy may be the ‘sticking plaster of cancer’ but it is likely to be necessary
for many decades to come and it merits continual development.
Intensity-modulated radiotherapy (IMRT) has widened
the horizons of radiation therapy due to its ability to
conformradiation dose distributions to complex tumor
target volumes while sparing nearby critical structures
as much as physically possible. IMRT has also led to
paradigm shifts in all elements of the chain of radiotherapy,
from treatment prescription over treatment
planning (“inverse” planning) to treatment delivery and
There is a weak evidence base for the effectiveness of complementary therapies in terms of pain control,
but they may improve wellbeing. Safety issues are also a consideration in this area.
Patients with cancer pain spend most of their time in the community until their last month of life. Older
patients and those in care homes in particular may have under-treated pain. Primary care teams supported
by palliative care teams are best placed to initiate and manage cancer pain therapy, but education of
patients, carers and healthcare professionals is essential to improve outcomes.

The contribution of IT networks to improving or compromising equipment functionality can
bear on both justification and optimization. This can apply to both PACS or RIS networks in
diagnostic imaging, and planning and treatment networks in radiotherapy centres. The
requirements for acceptability of such networks are beyond the scope of this report. Likewise
display monitors and viewing boxes are not treated here.
As already mentioned, this report focuses on qualitative criteria and suspension levels. It is
not intended to provide a template for quality assurance programmes.
