Biomarkers for ovarian cancer

Abstract

The present invention provides protein-based biomarkers and biomarker combinations that am useful in qualifying ovarian cancer status in a patient. In particular, the biomarkers of this invention are useful to classify a subject sample as ovarian cancer, ovarian cancer of low malignant potential, benign ovarian disease or other malignant condition. The biomarkers can be detected by SELDI mass spectrometry.

1 . A method for qualifying ovarian cancer status in a subject comprising:
 (a) measuring by immunoassay or mass spectroscopy at least one biomarker in a biological sample selected from blood, serum, plasma, and ovarian cyst fluid from the subject using the composition of  claim 32 ; and   (b) correlating the measurement with ovarian cancer status.

         8 - 11 . (canceled) 
     
     
         12 . The method of  claim 1 , wherein the correlating is performed by a software classification algorithm. 
     
     
         13 . The method of  claim 1 , wherein ovarian cancer status is selected from benign ovarian disease, ovarian cancer of low malignant potential, ovarian cancer and other malignant conditions. 
     
     
         14 - 15 . (canceled) 
     
     
         16 . The method of  claim 1 , wherein the ovarian cancer status rules out the possibility of benign ovarian disease or rules out the possibility of ovarian cancer. 
     
     
         17 . (canceled) 
     
     
         18 . The method of  claim 1 , further comprising: (c) managing subject treatment based on the status. 
     
     
         19 . The method of  claim 1 , further comprising: (c) reporting the status to the subject. 
     
     
         20 . The method of  claim 1 , further comprising: (c) recording the status on a tangible medium. 
     
     
         21 - 22 . (canceled) 
     
     
         23 . The method of  claim 18 , wherein, if the measurement correlates with ovarian cancer, then managing subject treatment comprises administering a chemotherapeutic agent to the subject. 
     
     
         24 . The method of  claim 18 , further comprising: (d) measuring the at least one biomarker after subject management and correlating the measurement with disease progression. 
     
     
         25 - 31 . (canceled) 
     
     
         32 . A composition comprising CA125, HE4, transferrin, and ApoA1 for qualifying ovarian cancer in a subject. 
     
     
         33 . A composition for qualifying ovarian cancer comprising a panel of biospecific capture reagents, each of which specifically binds a biomarker, such that the panel binds CA125, HE4, transferrin, and ApoA1. 
     
     
         34 . The composition of  claim 33 , wherein the biospecific capture reagent is an antibody. 
     
     
         35 . The composition of  claim 33 , wherein each biospecific capture reagent is bound to a solid support. 
     
     
         36 . (canceled) 
     
     
         37 . A kit comprising the composition of  claim 33 , bound to
 a solid support; and   instructions for using the composition in the method of  claim 1 .   
     
     
         38 - 68 . (canceled) 
     
     
         69 . The composition of  claim 35 , wherein the solid support is selected from the group consisting of a bead, plate, membrane, array, or chip.
