Early endometrial cancer blood test

We all know that if we want to better diagnose certain diseases, we must do some related examination items so that we can better diagnose the disease, so as to buy time for the treatment of the disease. If a diagnosis is correct, then its treatment process will also be good and the time will be shortened. So for the disease of endometrial cancer, what are its examination items?

1. Hysteroscopy

At present, hysteroscopy has been widely used in the diagnosis of endometrial lesions. Fiber hysteroscopy is the most widely used in China. About 20% of patients with postmenopausal vaginal bleeding have endometrial cancer. The use of hysteroscopy can directly observe the cervical canal and uterine cavity, detect lesions and accurately take biopsies, which can improve the diagnosis rate of biopsy and avoid missed diagnoses in conventional diagnosis and curettage. It can also provide information such as the scope of the lesion and whether the cervical canal is involved, and assist in correct clinical staging before surgery. However, due to the injection of uterine distension fluid during hysteroscopy, it is possible that it will flow into the pelvic cavity through the fallopian tubes, causing cancer cells to spread and affecting the prognosis. This should be noted.

2. Cystoscopy and proctoscopy

It is important to determine whether there is tumor invasion, but biopsy confirmation is required to confirm bladder or rectal involvement.

3. Lymphangiography

Computed tomography (CT) and magnetic resonance imaging (MRI) show that lymph node metastasis is the main route of spread of endometrial cancer. Literature reports that the lymph node metastasis rate of stage I endometrial cancer is 10.6%, and that of stage II is 36.5%. Lymph node angiography can be used in preoperative examination to predict whether lymph nodes have metastasis, but the operation is complicated and puncture is difficult, making it difficult to promote clinical application. Since the application of the new surgical-pathological staging of FIG0 in 1989, surgical pathological examination can determine whether lymph nodes have metastasis and accurately judge the prognosis. The scope of application of lymph node angiography has been narrower than before. CT, MRI, etc. are mainly used to understand the uterine cavity, cervical lesions, depth of myometrial invasion, whether lymph nodes have grown (more than 2 cm), etc. Due to their high cost, they have not yet been used as routine examinations. At present, it is believed that MRI has great value in providing imaging information such as myometrial invasion and whether retroperitoneal lymph node metastasis, and can be used to guide treatment (FIGO, 2003).

4. B-mode ultrasound examination

In recent years, B-mode ultrasound examination has developed rapidly, especially transvaginal B-mode ultrasound examination, which has been widely used in gynecological clinic (transvaginalultransoundexamination, TVB). It has made certain progress in assisting the diagnosis of endometrial lesions. Transvaginal B-mode ultrasound examination can understand the size of the uterus, the shape of the uterine cavity, the presence of vegetation in the uterine cavity, the thickness of the endometrium, the presence of infiltration and depth of the myometrium (Sahakian, 1991), and provide a reference for clinical diagnosis and pathological sampling (uterine cavity biopsy, or curettage). For postmenopausal women with uterine bleeding, further diagnosis methods can be selected based on the results of transvaginal B-mode ultrasound examination.

I believe that after understanding the above introduction, you will have a clearer understanding of the relevant examination items for endometrial cancer. These are the examination items for endometrial cancer. If similar symptoms of endometrial cancer appear in your life, you must go to the hospital for relevant examinations, which can shorten the treatment time and better diagnose the disease.
