Analysis of the best treatment for cervical precancerous lesions

Cervical precancerous lesions are cancerous changes in the female cervix. Early treatment of cervical precancerous lesions is very likely to lead to cure. The main treatment methods include surgery, radiotherapy, chemotherapy, and Chinese medicine. In the early stage, several combined treatments can be used, with surgery as the main treatment. Before surgery, radiotherapy and chemotherapy can be performed to increase the success rate of the surgery. At the same time, Chinese medicine can also be used to prevent complications. The specific treatment method should be selected according to the condition.

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, ureterovaginal fistula, etc.

(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.
