title: Molecular genetics of gynecologic cancer.
abstract: During the past decades, the expansion of molecular biology has had a pivotal role in understanding the basis of cancer development and progression. In addition, real advances have been made in the application of DNA recombinant technology to cancer therapy and patient management. In gynecologic oncologic fields, there are also many investigations to explore the basic pathogenesis of gynecologic cancer, such as cervical cancer, ovarian cancer, and endometrial cancer. It is now known that specific types of human papilloma virus (HPV) are the principal etiologic agents for both cervical cancer and its precursors. However, the various kinds of alterations in oncogenes and tumor suppressor genes may play additional roles in carcinogenesis of cervical cancer. Although ovarian carcinoma is the most frequent cause of death from gynecologic malignancies, the histogenesis and biological characteristics of these tumors are not well understood. During the last several years, many key observations have been made concerning the genetic alterations associated with ovarian cancer. Recent researches including some dominant oncogenes and tumor suppressor gene mutations common to these malignancies are providing bases to elucidate the mechanisms underlying this cancer. The most important basis of endometrial cancer is that K-ras and p53 mutations are also frequently observed.
