Advances in gastrointestinal cancer therapy: Spotlight on nanoarchitectures considers applications of nanostructures in treatment of gastrointestinal tumors and their capacity in improving efficacy of therapeutics, The book has a strong focus on overcoming challenges in gastrointestinal cancer therapies such as drug resistance, introduction of nanomedicine for drug and gene delivery, and new insight for clinical trials in treatment of patients with gastrointestinal tumors. In 25 chapters Advances in gastrointestinal cancer therapy: Spotlight on nanoarchitectures describes the multiple problems in treatment of gastrointestinal cancers including drug resistance, radio-resistance, inability to reaching to tumor site, degradation of genetic tools by RNase enzymes, and acidic pH of tumor microenvironment that may negatively affect efficacy of chemotherapeutic agents by making changes in their structure. This book is a valuable resource for Students, researchers and academicians in oncology and medical engineering.
