Cancer chemotherapy frequently attacks the gastrointestinal tract. Many of the possible side-effects reduce the patient's quality of life, may limit acceptance of further drug administration, and even life-threatening complications must be considered. This book is the proceedings of the Falk Workshop 'Side-effects of Chemotherapy on the Gastrointestinal Tract: Pathogenesis and Therapy', held in Freiburg, Germany, on October 11, 2002 (Part IV of the Freiburg Gastroenterology Week). Chapters by pathologists, pharmacologists, oncologists and gastroenterologists will improve our understanding of the effects of anticancer agents on the organs of the gastrointestinal tract and help to compensate for chemotherapy-induced adverse effects.
