Description

Technical Field

[0001] The present application relates to the field of intraocular lymphoma auxiliary diagnosis technology, and more specifically, it relates to an intraocular lymphoma detection reagent and detection method. Background Art

[0002] Intraocular lymphoma is usually divided into primary vitreoretinal lymphoma, primary choroidal lymphoma and intraocular metastasis of systemic lymphoma. It is a malignant tumor with relatively complex diagnosis. The complexity of diagnosis is mainly reflected in the small amount of intraocular fluid samples. Routine pathological examinations often encounter insufficient sample volume, but pathology is the gold standard for the diagnosis of lymphoma.

[0003] Flow cytometry immunophenotyping is a useful supplement to pathology. It detects multiple cell parameters at the same time, including cell number, size, surface antigens, etc. It can be used for auxiliary diagnosis in the diagnosis of intraocular lymphoma. The main advantage of the technology is that it can analyze trace amounts of cells.

[0004] Some highly suspected patients need to undergo repeated intraocular fluid testing to measure the levels of interleukins IL-10 and IL-6 in the intraocular fluid, which has a certain suggestive effect on the diagnosis of B-cell-derived primary vitreoretinal lymphoma. If the ratio of IL-10 to IL-6 is greater than 1, it indicates the possibility of lymphoma, and further related tests should be performed to confirm the diagnosis.

[0005] Although intraocular lymphoma is mainly derived from B cells, a small number of them are derived from T cells or NK cells. There is no literature proving that IL-10 concentration is related to lymphomas of T cells and other sources. In addition, there are patients with intraocular B cell-derived lymphoma whose IL-10 concentration is not detected to be elevated. Therefore, the determination of IL-10 and IL-6 content has a certain suggestive effect on the diagnosis of B cell-derived primary vitreoretinal lymphoma, but cannot assist in the diagnosis of T cell-derived lymphoma and NK cell-derived lymphoma. Summary of the invention

[0006] In order to improve the accuracy of auxiliary diagnosis of intraocular lymphoma, the present application provides an intraocular lymphoma detection reagent and detection method.

[0007] In a first aspect, the present application provides an intraocular lymphoma detection reagent, which adopts the following technical solution:

[0008] A reagent for detecting intraocular lymphoma comprises a first reagent, wherein the first reagent comprises at least five of CD117 antibody, CD56 antibody, CD45 antibody, CD38 antibody, CD34 antibody, CD33 antibody, CD19 antibody, CD13 antibody, CD7 antibody, kappa antibody and lambda antibody.

[0009] By adopting the above technical solution, the specific expression of CD molecules indicates a specific disease, which is suitable for clinical auxiliary diagnosis of lymphoma, and the test results are highly accurate. According to the test results of the first reagent, preliminary screening and judgment can be carried out to confirm the major types of lymphoma.

[0010] The kappa / lambda ratio is used to distinguish malignant lymphoma from benign lymphoma.

[0011] Abnormal expression of CD56: ① NK large granular lymphocytic leukemia, occasionally expressed in T-cell large granular lymphocytic leukemia; ② primitive NK cell leukemia / lymphoma; progressive NK cell leukemia / lymphoma; ③ nasal type NK cell lymphoma; ④ many acute myeloid leukemias; ⑤ can be expressed in multiple myeloma, sometimes in plasma cell leukemia; ⑥ some lung and nerve-related tumors (such as neuroblastoma, astrocytoma); ⑦ CD56 expression is associated with poor prognosis of AML with t(8;21) and t(15;17).

[0012] Abnormal expression of CD33: Most acute myeloid leukemias, especially M3 and M5, tend to show high expression; it may be weakly expressed in some acute lymphocytic leukemias.

[0013] Abnormal expression of CD13: Most of the primitive cells of acute myeloid leukemia, M6 and M7 may express negatively; some myeloma cells.

[0014] Abnormal expression of CD117: Most acute myeloid leukemia blasts; systemic mastocytosis; some myeloma cells (except plasma cell leukemia); rarely, it can be expressed in acute T-lymphocytic leukemia.

[0015] Abnormal expression of CD34: most acute myeloid leukemias; most acute B-lymphocytic leukemias (Pro-B or Common B, but pre-B and mature B do not express CD34); some acute T-lymphocytic leukemias.

[0016] Abnormal expression of CD7: 1. The original cells of acute T-lymphocytic leukemia; 2. T-lineage prolymphocytic leukemia cells; 3. T-lineage leukemia / lymphoma tumor cells; 4. Some acute myeloid leukemias. In this case, the expression of CD7 is helpful for monitoring the residual lesions of AML.

[0017] Abnormal expression of CD19: expressed in primitive cells of acute T-cell leukemia and tumor cells of mature T-cell leukemia / lymphoma.

[0018] Abnormal expression of CD38: myeloma cells, primary effusion lymphoma, some splenic lymphomas with villous lymphocytes, some chronic lymphocytic leukemias.

[0019] Abnormal expression of CD45: 1. Most acute T-lymphocytic leukemias express high levels of CD45, while 20% of acute B-lymphocytic leukemias are negative. 2. Acute myeloid leukemia weakly expresses CD45. 3. Neoplastic mast cells. 4. Both Hodgkin's cells and Reese's cells are CD45 negative, but Hodgkin's disease with nodular lymphocytes as the main type is CD45 positive. 5. It can occasionally be expressed in myeloma cells.

[0020] Optionally, the first reagent includes CD117 antibody, CD56 antibody, CD45 antibody, CD38 antibody, CD34 antibody, CD33 antibody, CD19 antibody, CD13 antibody, CD7 antibody, kappa antibody and lambda antibody.

[0021] By adopting the above technical solution, the screening of antibodies needs to take into account mutual interference and the synergy of expression prompt information. The combination of eleven antibodies in the first reagent can better achieve accurate screening of major lymphoma categories and provide a basis for subsequent auxiliary diagnosis of specific diseases.

[0022] For a 10-color flow cytometer, although only 10 channels of antibodies can be matched at a time, Kappa and CD56 have the same fluorescence and can use the same channel. Kappa and CD56 are expressed on different cells and do not interfere with each other. Therefore, the antibody combination of the first reagent can make full use of the channels of the flow cytometer, complete the initial screening at one time, and the accuracy of the initial screening results is high.

[0023] Optionally, a second reagent is also included, which includes CD16 antibody, CD22 antibody, CD4 antibody, CD5 antibody, CD23 antibody, CD20 antibody, CD3 antibody, CD138 antibody, CD19 antibody, CD8 antibody, CD45 antibody, CD300e antibody, CD64 antibody, CD123 antibody, CD85K antibody, CD14 antibody, CD36 antibody, CD2 antibody, CD11b antibody, CD303 antibody, CD71 antibody, CD304 antibody, CD10 antibody, MPO antibody, CD79a antibody, FMC7 antibody, IgM antibody, CD103 antibody, CD95 antibody, CD39 antibody, CD11c At least ten of the group consisting of antibody, CD30 antibody, CD25 antibody, CD40 antibody, CD43 antibody, BCL-2 antibody, CD200 antibody, ki-67 antibody, CD56 antibody, CD38 antibody, Kappa antibody, Lambda antibody, CD27 antibody, CD81 antibody, CD28 antibody, TdT antibody, CD9 antibody, CD66c antibody, HLA-DR antibody, CD307d antibody, CD1a antibody, CD57 antibody, CD45RA antibody, CD158e1 antibody, CD158e2 antibody, CD158b antibody, CD158i antibody, CD158f antibody, CD158a antibody and CD158h antibody.

[0024] Optionally, the second reagent comprises at least twenty antibodies.

[0026] Optionally, a third reagent is also included, and the third reagent includes a kit for detecting IL-2, IL-4, IL-6, IL-10, IFN-γ and TNF-α in intraocular fluid.

[0027] By adopting the above technical solutions, some CD molecules that are not expressed obviously need to be analyzed in combination with cytokine conditions. An increase of more than 10 times in IL-10 alone and an increase in IFN-γ may indicate hemophilia, and EB virus infection and other possibilities need to be ruled out. IL-2, IFN-γ and TNF-α levels are significantly reduced, and a slight increase in IL-6 and IL-10 levels indicates possible progression of the tumor microenvironment. A significant increase in IL-4 may indicate an allergic reaction.

[0028] Optionally, each antibody in the first reagent is labeled with a fluorescent marker; and each antibody selected in the second reagent is labeled with a fluorescent marker.

[0035] By adopting the above technical scheme, after (2) initial screening, the major types of lymphoma, B type, T type or NK type, are confirmed.

[0036] Optionally, it also includes (3) typing, the specific process of which is as follows:

[0037] Determining the antibody combination selected for the second reagent based on the results of the initial screening of (2);

[0038] The concentrated sample and the second reagent were mixed evenly, and then incubated in the dark, followed by washing with PBS buffer, centrifugation continued, the supernatant was removed, and then PBS buffer was added and resuspended to obtain the test sample B;

[0045] Using flow cytometry to test sample C and obtain data;

[0046] The third reagent includes reagents for detecting IL-2, IL-4, IL-6, IL-10, IFN-γ and TNF-α in intraocular fluid.

[0047] By adopting the above technical scheme, some CD molecules with unclear expression should be analyzed in combination with cytokine status.

[0048] Optionally, the intraocular fluid sample is aqueous humor or vitreous humor.

[0113] Application examples:

[0114] The patient was a 70-year-old female who was diagnosed with decreased vision and bleeding. Vitreous mixing was found during the examination, and intraocular lymphoma was clinically considered. The intraocular lymphoma detection method of the embodiment of the present application was used for detection, and the detection instrument was BD FACS Canto IIPLUS (3 lasers and 10 colors).

[0115] Test results such as Figure 1 , Figure 2 As shown in the figure, (2) in the initial screening results, abnormal B cell populations accounted for 72.312% of the total. (3) In the typing results, CD19+ indicates lymphoma; CD20++ indicates B cell lymphoma; CD22+ indicates B cell lymphoma; CD38+ indicates normal early B and germinal center B cells, but the result shows CD38-, indicating B cell abnormality; CD5+ indicates normal B cells, but the result shows CD5-, indicating B cell abnormality; CD10+ indicates normal early B cells, germinal center B cells and non-neoplastic immature B cells, but the result shows CD10-, indicating B cell abnormality; light chain deletion indicates B cell abnormality.

[0116] The significant increase in IL-10 and IL-6 indicated B-cell lymphoma. After examination, the patient was transferred to a specialized cancer hospital for further treatment.
