Back Jacket This book comprehensively summarizes the biology, etiology, and pathology of ovarian cancer and explores the role of deep molecular and cellular profiling in the advancement of precision medicine. The initial chapter discusses our current understanding of the origin, development, progression and tumorigenesis of ovarian cancer. In turn, the book highlights the development of resistance, disease occurrence, and poor prognosis that are the hallmarks of ovarian cancer. The book then reviews the role of deep molecular and cellular profiling to overcome challenges that are associated with the treatment of ovarian cancer. It explores the use of genome-wide association analysis to identify genetic variants for the evaluation of ovarian carcinoma risk and prognostic prediction. Lastly, it highlights various diagnostic and prognostic ovarian cancer biomarkers for the development of molecular-targeted therapy. Author Biography Khalid El Bairi is the principal investigator of OVANORDEST studies and the founder of The Cancer Biomarkers Working Group, and he is currently pursuing clinical and translational research in medical oncology. He has published many peerreviewed articles in the field of predictive and prognostic cancer biomarkers to improve survival outcomes in several WoS and Medline-indexed journals. His research focuses particularly on biomarkers for digestive and gynecological cancers such as ovarian and colorectal malignancies. He is currently a member of the board of various international scientific societies such as the International Gynecologic Cancer Society (IGCS), European Society for Medical Oncology (ESMO), American Society of Clinical Oncology (ASCO), European Society of Gynaecological Oncology (ESGO), and the American Association for Cancer Research (AACR).
