Biomarkers for ovarian cancer
View Patent ↗The present invention provides protein-based biomarkers and biomarker combinations that are useful in qualifying ovarian cancer status in a patient. In particular, it has been found that the biomarkers set forth in Table 1 are biomarkers for ovarian cancer. The biomarkers can be detected by SELDI mass spectrometry.
1. A method for diagnosing ovarian cancer in a subject comprising:
(a) measuring in a urine sample from the subject Small MBL-associated protein C-terminal fragment (sMAP), and
(b) correlating the measurement with ovarian cancer, wherein an elevated level of sMAP as compared to the level of sMAP from a reference subject that does not have ovarian cancer indicates the subject has ovarian cancer, thereby diagnosing ovarian cancer in the subject.
2. The method of claim 1 , wherein sMAP is measured by mass spectrometry.
3. The method of claim 2 , wherein mass spectrometry is SELDI-MS.
4. The method of claim 1 , wherein sMAP is measured by immunoassay.
5. The method of claim 1 , wherein the correlating is performed by executing a software classification algorithm.
6. The method of claim 1 , further comprising: (c) reporting the diagnosis to the subject.
7. The method of claim 1 , further comprising: recording the diagnosis on a tangible medium.
8. The method of claim 1 , further comprising: (c) managing subject treatment based on the diagnosis.
9. The method of claim 8 , further comprising: (d) measuring sMAP after subject management and correlating the measurement with disease progression.
