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. Taking advantage of practical availability of the physical characters including decay modes, half-lives, and decay energies of the radioisotopes, various practical insertion or deployment methods have been developed. Some of these are technically sophisticated. A precise treatment planning requires accurate dose calculation algorithm even in brachytherapy. In the clinical practice of brachytherapy, safe interventional procedures are indispensable.
Reverse, a simultaneous intervention modifying the surrounding structure may be practically applicable. In the first section, In Physics of Brachytherapy, Zehtabian et al. addresses the problem of currently popular dosimetric method (AAPM TG-43) based on experimental data.
Orion et al. reports a potential benefit of Monte Carlo method in dose calculations of ruthenim-106/rhodium-106 (beta emitters) eyes applicators. In the second section, Californium, Wang present an excellent review of Progress in Californium-252 (Cf-252) Neutron Brachytherapy, including history, availability, fabrication, biological basis, dosimetry and clinical data including promising future possibilities. In the third section, Practice of Brachytherapy, Santini et al. reports their clinical case series study of high dose rate endobronchial brachytherapy in central airway tumor obstruction.
Impressive result indicate a singinficant rationale of brachytherapy in this situation. Zeituni et al. elaborate a comprehensive review from principle and techniques of Iodine-125 production at nuclear reactor plant to their clinical practive in prostate cancer treatment. In the last section, Novel Strategy and Applications, Ruge et al present a very interesting review with their clinical practices of Stereotactic Brachytherapy for Brain Tumors using Iodine-125 seed. We may reappraise our current concepts in the treatment of gliomas that has never been satisfactory controlled. In the last chapter, Kishi et al introduce a brachytherapy procedure with organ-sparing hyaluronate gel injection as a simultaneous intervention, which enabled safe and eradicative reirradiation, by modifying the surrounding structure during the irradiation. Though this book is not an unabridged review of brachytherapy, it is full of essences to make a breakthrough in radiation oncology by brachytherapy. I hope this book will encourage all people from related fields.
