  • 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 AND HOW? Scientific rationale 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 verification.

  • 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.
