OBJECTIVE To investigate the prognostic significance of elevated levels of cancer antigen 125 (CA125), placental alkaline phosphatase (PLAP), free beta human chorionic gonadotrophin (hCG) and cancer-associated serum antigen (CASA) in women with primary epithelial ovarian carcinoma. METHODS A two year follow up study of survival. METHODS A tertiary care gynaecological oncology unit. METHODS One hundred and eleven women with histologically confirmed epithelial ovarian cancer. METHODS Survival over a two year period. RESULTS Stage corrected log-rank chi 2 tests demonstrated a significant effect on survival for all four tumour markers (CA125 P = 0.0142; PLAP P < 0.0001; CASA P = 0.0098; hCG P = 0.0002). This was confirmed when each variable was fitted together with disease stage in Cox proportional hazard models. When fitted as multiple variables in a Cox proportional hazard model, the addition of free beta-hCG and CASA to disease stage, PLAP concentrations and CA125 levels did not demonstrate further prognostic value. CONCLUSIONS Levels of all four markers correlate with survival in patients with epithelial ovarian cancer. The combination of PLAP and CA125 concentrations together with disease stage may be used to predict survival but the addition of hCG and CASA levels do not give additional prognostic information.

UI MeSH Term Description Entries
D007527 Isoenzymes Structurally related forms of an enzyme. Each isoenzyme has the same mechanism and classification, but differs in its chemical, physical, or immunological characteristics. Alloenzyme,Allozyme,Isoenzyme,Isozyme,Isozymes,Alloenzymes,Allozymes
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm. Proteins, Neoplasm
D010051 Ovarian Neoplasms Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.

D006063 Chorionic Gonadotropin A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
