Laser cure rate of cervical precancerous lesions

Cervical precancerous lesions refer to malignant tumors that appear in the female cervix. Cervical precancerous lesions are the leading cause of female malignant tumors, and are most common in patients between the ages of 40 and 55, with a high mortality rate. So how should cervical precancerous lesions be treated? What are the treatment methods?

1. Surgical treatment

Extensive hysterectomy and pelvic lymph node removal are performed. The removal range includes the entire uterus, bilateral adnexa, upper vagina and paravaginal tissues, and pelvic lymph nodes (paracervical, obturator, internal iliac, external iliac, and lower common iliac lymph nodes). The operation requires thoroughness, safety, strict control of indications, and prevention of complications.

2. Surgical complications and their treatment

1. Surgical complications include intraoperative bleeding, postoperative pelvic infection, lymphocele, retention, urinary tract infection and ureterovaginal fistula.

2. Treatment of surgical complications. In recent years, the incidence of the above complications has been significantly reduced due to improvements in surgical methods and anesthesia techniques, the use of preventive antibiotics, and the use of extraperitoneal negative pressure drainage after surgery.

3. Radiation therapy

It is the first choice for the treatment of cervical precancerous lesions and can be applied to cervical precancerous lesions of all stages. The radiation range includes the cervix and the affected vagina, uterine body, paracervical tissue and pelvic lymph nodes. The irradiation method generally adopts a combination of internal and external irradiation. Internal irradiation is mainly aimed at the primary lesion of the cervix and its adjacent parts, including the uterine body, the upper part of the vagina and its adjacent paracervical tissue ("A") point.

4. Chemotherapy

So far, cervical precancerous lesions are insensitive to most anticancer drugs, and the effective rate of chemotherapy is no more than 15%. Advanced patients can be treated with comprehensive treatments such as chemotherapy and radiotherapy. Chemotherapy drugs such as 5-fluorouracil and doxorubicin can be injected intravenously or locally.

The above mainly introduces four methods for treating cervical precancerous lesions. The above methods are all commonly used treatments for cervical precancerous lesions. In addition to the above methods, there is also a method of adjuvant treatment with Chinese medicine, which is mainly a conservative treatment to relieve the pain of patients.
