The protecting, lysis and inhibiting solution inhibits endogenous degrading enzymes in the cervical secretion and mucus. Protected cells and tissues are prepare for morphology based cytology and histology test. Protected bio-molecules including HPV DNA, E6E7 mRNA, miR-200a and miR-9 miRNA, and E6E7 protein are isolated for molecular tests, immunology, and mass spectrum test. HPV DNA, E6E7 mRNA, miR-200a and miR-9 miRNA, and E6E7 protein are isolated, after lysis or homogenization of cervical secretion and mucus, by performing a differential centrifugation process, a differential precipitation process and a differential solid phase binding process on the lysate without toxic phenol/chloroform extraction to separate the HPV DNA, E6E7 mRNA, miR-200a and miR-9 miRNA, and E6E7 protein.
The systems diagnosis of cervical cancer is carried out through tests of cells, tissues, and bio-molecules derived from cervical secretion and mucus on aspects of cytology and histological structures and micromorphology of epithelia cells and biopsy tissues; molecular biology test of HPV DNA, E6/E7 mRNA, miR-200a and miR-9; and immunology test of E6/E7 protein. Epithelia cells and biopsy tissues are tested by conventional cytology and histology routinely practice in pathology laboratory; HPV DNA is tested by methods of molecular test including Hybridization (HPV DNA Hybrid Capture assay from Qiagen Digene, U.S. Pat. No. 7,361,460), Polymerase Chain Reaction (PCR) (AMPLICOR HPV Test (CE-IVD) from Roche Diagnostics) or microarray; E6/E7 mRNA is tested by methods of molecular test, Reverse Transcription Polymerase Chain Reaction (RT-PCR), or APTIMA E6/E7 mRNA test from Hologic Gen-Probe (U.S. Pat. No. 7,354,719; incorporated herein in its entirety); E6/E7 protein is tested by method of immunoassay (U.S. Pat. No. 6,933,123); and miRNA 200a and miRNA-9 are tested by method of molecular test, RT-PCR (Cancer Research. 2010 Feb. 15; 70(4):1441-8.).
The results of above tests represent different aspects of the cervical cancer status. Molecular tests such as HPV DNA test and E6/E7 mRNA tests are primary screen methods with high sensitivity and efficiency for earlier stage screening. High risk HPV, such as HPV 16 or 18 have higher potent to cause cervical cancer, which should be taken seriously with aggressive actions; Expression of E6/E7 mRNA and protein indicates whether or not the HPV has become active in triggering the cancerous process. Detection of E6/E7 mRNA as a marker of high risk HPV infection will find out whether the infection may be dormant (harmless) or active (potentially harmful). Therefore, E6/E7 mRNA-based tests may help reduce the number of women who need to undergo further treatment, such as colposcopy.
Conventional cytology test is secondary screen method for pre-cancer. Cervical Intraepithelial Neoplasia (CIN) results can serve as further triage for primary screen tests. CIN1 is mild dysplasia and my not require colposcopy, whereas carcinoma In Situ (CIS)/CIN2/CIN3/are moderate and severe dysplasia and aggressive actions are advised. Conventional histology test will confirm the pathological diagnosis for adenocarcinoma in Situ, micro-invasive squamous carcinoma, invasive squamous or glandular carcinoma, which are indications for aggressive surgical, chemical or radiation treatments. miRNA 200a and miRNA-9 test serves prognosis of cervical cancer and predict patient survival. Both miR-200a and miR-9 could play important regulatory roles in cervical cancer control. In particular, miR-200a is likely to affect the metastatic potential of cervical cancer cells by coordinate suppression of multiple genes controlling cell motility.
The systems diagnosis of cervical cancer is achieved by integrating comprehensive parameters from preventive screen test of high risk HPV DNA to identify high risk of population to suffer from cervical cancer in the future; test of E6/E7 mRNA and E6/E7 protein for treatment triage; test of micromorphology changes of epithelia cells to screen population to have cervical pre-cancer; test of histology changes to confirm the diagnosis of cervical cancer; and test of expression signature miR-200a and miR-9 for cervical cancer prognosis. The results of systems diagnosis of cervical cancer will provide better management of cervical cancer than individualized and separated test results, increase the efficiency and reduce the cost for testing laboratory as well as patients, therefore benefit patients with cervical cancer.
The invention has been described using exemplary preferred embodiments. However, for those skilled in this field, the preferred embodiments can be easily adapted and modified to suit additional applications without departing from the spirit and scope of this invention. Thus, it is to be understood that the scope of the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements based upon the same operating principle. The scope of the claims, therefore, should be accorded the broadest interpretations so as to encompass all such modifications and similar arrangements. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
This application claims priority from and is a cont-in-part (CIP) of U.S. non-provisional patent application Ser. No. 12/979,383 filed on Dec. 28, 2010 which are incorporated herein by reference.
