Since the first clinical trials on Boron Neutron Capture Therapy in the 1950s, BNCT research has been mainly focussed on the treatment of (deep-seated) brain tumours, in particular, glioblastoma multiforme. Promising work to treat other cancers at other locations and even other diseases are in progress. Therefore, the chemists, medical doctors, physicists and biologists involved in BNCT are not only continuing to investigate and improve the (brain) clinical results, but are also investigating the new applications in BNCT. The work presented in this thesis is in the field of physics and deals, from three different viewpoints, with obtaining the optimal source neutron energy to optimise BNCT. The optimal source neutron energy is defined such as to obtain as many as possible (n, a)-absorptions due to 10B in the tumours and as low as possible total neutron dose in the healthy tissues and organs at risk

Neutron capture therapy (NCT) is based on the ability of the non-radioactive isotope boron-10 to capture thermal neutrons with very high probability and immediately to release heavy particles with a path length of one cell diameter, which in principle allows for tumor cell-selective high-LET particle radiotherapy. This book provides a comprehensive summary of the progress made in NCT in recent years. Individual sections cover all important aspects, including neutron sources, boron chemistry, drugs for NCT, dosimetry, and radiation biology. The use of NCT in a variety of malignancies and also some non-malignant diseases is extensively discussed. NCT is clearly shown to be a promising modality at the threshold of wider clinical application. All of the chapters are written by experienced specialists in language that will be readily understood by all participating disciplines.

For this Workshop, the organizers have attempted to invite experts from all known centers which are engaged in neutron beam development for neutron capture therapy. The Workshop was designed around a series of nineteen invited papers which dealt with neutron source design and development and beam characterization and performance. Emphasis was placed on epithermal beams because they offer clinical advantages and are more challenging to implement than thermal beams. Fission reactor sources were the basis for the majority of the papers; however three papers dealt with accelerator neutron sources. An additional three invited papers provided a summary of clinical results of Ncr therapy in Japan between 1968 and 1989 and overviews of clinical considerations for neutron capture therapy and of the status of tumor targeting chemical agents for Ncr. Five contributed poster papers dealing with NCT beam design and performance were also presented. A rapporteurs' paper was prepared after the Workshop to attempt to summarize the major aspects, issues, and conclusions which resulted from this Workshop. Many people contributed to both the smooth functioning of the Workshop and to the preparation of these proceedings. Special thanks are reserved for Ms. Dorothy K.

There are many human cancers which actively synthesize specific characteristic proteins such as melanomas, thyroid cancer and squamous cell carcinoma. Many cancer researchers have of course tried to utilize this specific activity as a key for the selective treatment of cancers. In the past for example, the molecular hybrid compound of DOPA, a substrate of melanin, and nitrogen mustard N-oxide hydrochloride, a ctyotoxic anti-tumor drug, was synthesized as Melphalan and used to treat malignant melanoma. A major problem arose though in that it was soon found to be highly suppressive toward bone marrow and quite toxic while not being remarkably effective. Thus, malignant melanoma could not be cured by it. Such failure led us to develop a novel bimodal therapeutic system which includes the use of non-toxic potentially cytocidal chemicals which selectively accumulate within the cancer cells and which are converted by a controllable modality into an actively cytocidal element in situ. We can now non-surgically cure malignant melanoma and glioblastoma with our selective cancer treatment, neutron capture therapy (NCT); as can be found in this volume. Included are 124 papers on the latest breaking developments discussed at the Sixth International Symposium on NCT for Cancer held in Kobe during the late autumn of 1994.

Frontiers in Neutron Capture Therapy contains current research results originally presented at the Eighth International Symposium on Neutron Capture Therapy for Cancer in La Jolla, CA. This comprehensive collection of peer-reviewed manuscripts is showcased in two volumes covering all aspects of the development of this multidisciplinary approach to cancer therapy. Volume I of this work includes clinical results and current progress in treatment planning, neutron sources and dosimetry, while Volume II presents the synthesis, pharmacology and tissue-targeting design of boron compounds, including work on preclinical dosimetry and radiobiology. Intended for researchers and clinicians involved with or interested in new modes of cancer therapy, this volume will also serve as a useful guideline for scientists, students, and practitioners in the field.

Binary systems for the treatment of cancer potentially are among the most attractive of the new therapeutic modalities that currently are under investigation. The basicconcept is to selectivelydestroy malignantcells whileconcomitantlysparing normal tissue. Neutron capture therapy (NCT) is the binary system that has been the subject of the Fifth International Symposium on Neutron Capture Therapy, which was held September13-17, 1992, in Columbus, Ohio, undertheauspicesoftheInternational Society for Neutron Capture Therapy. Its objective was to bring together researchers from throughout the world and to provide a forum at which they could present the latest advances in the development of Neutron capture therapy. Neutron capture therapy has largely, but not exclusively, focused on the use of boron-10 as the target nuclide. Boron neutron capture therapy (BNCT) is based on the nuclear reaction that occurs when the stable isotope, boron-10, absorbs low-energy non ionizing thermal neutrons to yield alphaparticles and recoiling lithium-7 nuclei. The size and energy of these high linear energy transfer (LET) particles result in their being confined largely to the cells in which the capture reaction occurs. For BNCT to be successful, a sufficient numberof I~atoms mustbe localized within neoplastic cells, and enough thermal neutrons must be delivered and absorbed by the I~ to produce a lethal 1~(n,QVLi reaction. Two major problems must be surmounted.

The book focuses on two concurrent experimental therapies in cancer treatment known as boron neutron capture therapy (BNCT) and gadolinium neutron capture therapy (GdNCT) using a variety of boron- and gadolinium-based compounds. Some of the gadolinium compounds serve the dual purpose as being MRI contrast agents and GdNCT agents. The book describes why BNCT & GdNCT were not at the forefront of the clinical trials during the past seven to eight decades since the discovery of neutrons by John Chadwick in 1932 and how the latest development in the synthesis of target boron- and gadolinium-based drugs have turned the area to be the hottest one and worthy of further investigation with the new clinical trials in the USA and elsewhere.
