Endometrial cancer is one of the most common tumors of the female reproductive system and is the third most common gynecologic malignancy causing death. In recent years, the incidence rate of endometrial cancer has been increasing year by year and the trend is younger. I. What are the risk factors of endometrial cancer? (1) Patients with hypertension, diabetes, obesity, polycystic ovary syndrome, infertility and delayed menopause; (2) Patients with long-term single application of estrogen, tamoxifen or other history of estrogen-increasing diseases; (3) Patients with family history of breast cancer and endometrial cancer. (2) What are the early symptoms of endometrial cancer? Early stage patients may have no obvious symptoms. The main clinical symptoms of endometrial cancer are: postmenopausal vaginal bleeding or premenopausal irregular vaginal bleeding, the latter is often neglected and mistaken for endocrine disorder, thus delaying the diagnosis; some patients also mistakenly think that it is normal before menopause and do not consult the doctor, but when they consult the doctor, the disease is already at a more advanced stage. In addition, increased vaginal discharge and abdominal pain should be alerted to endometrial cancer, and vaginal discharge with bloody leucorrhea may be misdiagnosed as vaginitis. Advanced stage patients may have swelling and pain in lower limbs; urinary tract symptoms, secondary anemia, emaciation, fever and other manifestations. III. How to diagnose endometrial cancer? (1) Ultrasound examination: Color ultrasound examination can understand the size of uterus, thickness of endometrium, whether there is uneven echogenicity or redundancy in the uterine cavity, myometrial infiltration and its degree. In particular, postmenopausal endometrial thickness greater than 150px and abnormal echogenicity in the uterus should be further diagnosed in a timely manner. (2) Segmental scraping: segmental scraping is to scrape the cervical canal and endometrial tissue separately and send them to pathology separately. It is the most common and valuable examination method to confirm the diagnosis of endometrial cancer. For patients with heavy vaginal bleeding or continuous bleeding, segmental scraping can also play a role in stopping bleeding. Segmental scraping can clarify the location of the lesion and whether the cancer invades the cervix, as well as the pathological type and malignancy of the tumor. (3) Hysteroscopy: Hysteroscopy can directly observe the presence of cancerous lesions in the uterine cavity and cervical canal, the location, shape, size and extent of cancerous lesions, as well as the involvement of cancer in the cervical canal; biopsy of suspicious lesions under direct vision can help to detect smaller or earlier lesions, and the latter can relatively reduce the leakage rate of endometrial cancer compared with segmental curettage. (4) Magnetic resonance imaging (MRI): MRI can clearly show the size and scope of endometrial cancer lesions, myofibrotic infiltration and metastasis of pelvic and para-aortic lymph nodes, etc., so as to estimate the tumor stage more accurately. (5) Tumor markers Serum CA125 is generally not elevated in early stage endometrial cancer patients, but it can be significantly elevated in advanced stage patients with extra-uterine metastasis, and can be used as a tumor marker to detect the progress of the disease and treatment effect. 4.What are the treatment means of endometrial cancer? Surgery is the main treatment method for endometrial cancer. For early stage patients, the purpose of surgery is surgical-pathological staging because accurate determination of lesion scope and staging is closely related to patient’s prognosis, removal of diseased uterus and possible metastatic lesions, and comprehensive staging is very important for the selection of postoperative adjuvant treatment plan for patients. Radiotherapy is one of the effective adjuvant treatment methods for endometrial cancer. Radiotherapy alone is only suitable for patients who are too old and frail and have severe medical comorbidities to tolerate surgery or are contraindicated for surgery. Chemotherapy is rarely used alone in the treatment of endometrial cancer, but is mostly used for special types of endometrial cancer, such as plasmacytosis and clear cell carcinoma; or recurrent cases; or post-surgical patients with high-risk factors for recurrence. Chinese herbal medicine treatment can be given to patients after surgery and radiotherapy to consolidate the root and support the righteousness and improve the immunity of the patient’s body.
