What are the symptoms of uterine fibroids? Is uterine fibroids a malignant tumor?

Uterine sarcoma is a rare and highly malignant female genital tumor. Histologically, it originates from the myometrium, or the connective tissue of the uterus or the endometrium. Sarcomas can be found in various parts of the uterus and are much more common than the cervix by about 15:1. Uterine sarcomas account for 2-5% of malignant uterine tumors, with an onset age of around 50 years, while cervical sarcomas are more common in young girls. Since there are no special symptoms in the early stage, the preoperative diagnosis rate is only 30-39%.

Symptoms:

1. Abnormal vaginal bleeding: It is the most common symptom of vaginal bleeding or menstrual abnormalities after menopause. .5%-78.2%

2. Abdominal mass: This is common in uterine fibroid tumors; the mass grows rapidly, and if the tumor grows into the vagina, the vaginal mass is often felt to be protruding. The uterus is often enlarged, irregular in shape, and soft in texture.

3. Abdominal pain: It is also a common symptom. Due to the rapid growth of fibroids, patients may experience abdominal pain or dull pain.

4. Increased vaginal discharge; may be serous, bloody or white, and may be purulent and foul-smelling when infected;

5. If the tumor is large, it may compress the bladder or rectum, causing irritation symptoms, and compress the veins, causing lower limb edema;

6. Late-stage patients may suffer from weight loss, anemia, fever, systemic exhaustion, pelvic mass infiltrating the pelvic wall, and immobility.

Diagnosis based on:

1. Uterine sarcoma has no special symptoms and signs, and its clinical manifestations are similar to other genital tract tumors. It has a low incidence and is easily overlooked. It is important to pay attention to improving the preoperative diagnosis rate;

2. Irregular vaginal bleeding before and after menopause or in children with uterine enlargement;

3. Uterine fibroids increase rapidly during menstruation, especially in postmenopausal patients, and the possibility of sarcoma should be considered;

4. Patients who have received radiotherapy before, sudden enlargement of the uterus, and abnormal vaginal bleeding;

5. Cervical neoplasms, curettage or hysterectomy specimens confirmed by pathology (but negative curettage cannot be excluded).

Treatment principles:

1. Surgery is the main treatment;

2. Radiotherapy: Uterine sarcoma has low sensitivity to radiotherapy, but preoperative radiotherapy can improve the resection rate for advanced patients, and postoperative radiotherapy has a certain effect on preventing local recurrence;

3. Chemotherapy.
