Markers for the early detection of colon cell proliferative disorders
Systems, media, compositions, methods, and kits disclosed herein relate to a panel of autoantibody biomarkers for the early detection of colon cell proliferative disorders, including colorectal cancer. The presence or levels of the autoantibodies in a biological sample for the autoantibody panels described herein may be used for classifier generation, and as inputs in machine learning models useful to classify subjects in a population for the detection of colon cell proliferative disorders.
1. A method of treating a colorectal cancer in a subject, comprising:
(a) obtaining an autoantibody profile of the subject, wherein the obtaining comprises assaying a biological sample obtained or derived from the subject to measure an amount of an autoantibody from a pre-determined set of autoantibodies, wherein the pre-determined set of autoantibodies comprises:
(i) IgM autoantibodies to at least three antigens selected from the group consisting of NME5, USP16, UBE2S, RNF41, CD20, and SDCBP;
(ii) IgM autoantibodies to at least three antigens selected from the group consisting of PELO, CDK4, MTP1, PRMT6, ZBTB2, and PCOLCE;
(iii) IgG autoantibodies to at least three antigens selected from the group consisting of ANKHD1, TXNL1, NAT6, Supt6h, PRDM8, OTUD5, PNKP, SRSF7, PCOLCE, and ASB9;
(iv) IgG autoantibodies to at least three antigens selected from the group consisting of TSSC4, BRD9, BCCIP, and TP53; or
(v) a combination of (i) to (iv);
(b) detecting the colorectal cancer in the subject, wherein the detecting comprises processing, by a computer specifically programmed to detect the colorectal cancer, the autoantibody profile using a trained machine learning model, wherein the trained machine learning model has been trained to distinguish between subjects with the colorectal cancer and subjects without the colorectal cancer; and
(c) responsive to the detecting in (b), administering to the subject a treatment for the colorectal cancer, wherein the treatment is selected from the group consisting of surgery, radiofrequency ablation, chemotherapy, radiation therapy, targeted therapy, and immune therapy.
2. The method of claim 1 , wherein the biological sample is selected from the group consisting of a body fluid, stool, colonic effluent, urine, blood plasma, blood serum, whole blood, isolated blood cells, cells isolated from the blood, tissue biopsy, and a combination thereof.
3. The method of claim 2 , wherein the biological sample is the blood plasma.
4. The method of claim 1 , wherein the colorectal cancer is selected from the group consisting of Lynch syndrome, colon cancer, rectal cancer, colorectal carcinoma, colorectal adenocarcinoma, carcinoid tumor, gastrointestinal carcinoid tumor, gastrointestinal stromal tumor (GIST), lymphoma, and sarcoma.
5. The method of claim 1 , wherein the pre-determined set of autoantibodies further comprises (i) IgM autoantibodies to at least three antigens selected from the group consisting of NME5, USP16, UBE2S, RNF41, CD20, and SDCBP.
6. The method of claim 1 , wherein the pre-determined set of autoantibodies further comprises (iii) IgG autoantibodies to at least three antigens selected from the group consisting of ANKHD1, TXNL1, NAT6, Supt6h, PRDM8, OTUD5, PNKP, SRSF7, PCOLCE, and ASB9.
7. The method of claim 1 , wherein the pre-determined set of autoantibodies further comprises (ii) IgM autoantibodies to at least three antigens selected from the group consisting of PELO, CDK4, MTP1, PRMT6, ZBTB2, and PCOLCE.
8. The method of claim 1 , wherein the pre-determined set of autoantibodies further comprises (iv) IgG autoantibodies to at least three antigens selected from the group consisting of TSSC4, BRD9, BCCIP, and TP53.
9. The method of claim 8 , wherein the pre-determined set of autoantibodies further comprises IgG autoantibodies to TP53.
10. The method of claim 1 , further comprising determining a methylation status of one or more nucleic acid molecules in the biological sample to provide a methylation profile of the subject.
11. The method of claim 10 , wherein (b) further comprises processing the methylation profile using the trained machine learning model.
12. The method of claim 1 , further comprising measuring an amount of one or more proteins in the biological sample to provide a protein profile of the subject.
13. The method of claim 12 , wherein (b) further comprises processing the protein profile using the trained machine learning model.
