| Περίληψη: | Foreword written by Samuel A. Wells, Jr., MD Professor of Surgery Duke University Medical Center, Durham, NC According to the American Cancer Society, about 1 million persons in the United States will be diagnosed with solid cancer every year. About 50% of them will be potentially cured by surgery. The other half of the population may develop metastatic cancer. To date, there is no systemic treatment available to cure metastatic cancer. Therefore, cancer clinical trials are critical to evaluate reliable treatment modalities against metastatic cancer. Likewise, adjuvant trials are needed to prevent high risk patients from developing recurrence following definitive surgical resection of their cancer. Only about 3-5% of the adult cancer patients are enrolled in clinical trials. When the pediatric cancer clinical trial groups were able to accrue over 40 percent of eligible patients to their clinical trials, significant impact was made on the survival of these pediatric cancer patients. However, multiple barriers exist to block adult cancer patients from entering into clinical protocols. The ever-changing regulations for clinical trials and the ethical dilemma of treating cancer patients as subjects have made it ever so difficult for the principal investigators to conduct clinical research, especially when they are often ill-informed of the complex nature of the regulations and over-worked. Therefore, cancer clinical trials are at a critical junction. The objective of this book is to bring the issues of cancer clinical trials into focus so that proactive strategies may be developed to make such trials more user-friendly. Ultimately, the cancer patients will be benefited. "Clinical trials remain the most important vehicle for improving the care of cancer patients. This text presents the fundamental components and challenges involving clinical investigations. Leading experts discuss the critical issues covering the spectrum of important topics from planning to application." Steven T. Rosen, M.D. Series Editor.
