What is the cure rate of cervical precancerous lesions?

What is the cure rate of cervical precancerous lesions? It takes about 10 years for a general cervical precancerous lesion to develop into cervical cancer. From this perspective, cervical cancer is not terrible. It is a preventable and curable disease. If prevented well, cervical precancerous lesions will not necessarily turn into cervical cancer.

1. Treatment principles

Atypical hyperplasia: If the biopsy is mild, the patient should be treated as an inflammatory patient for the time being. Follow-up scrapings and biopsy should be performed for half a year if necessary. If the lesion remains unchanged, the patient can continue to be observed. If the patient is diagnosed with moderate atypical hyperplasia, laser cryotherapy and electric ironing should be used. For severe atypical hyperplasia, total hysterectomy is generally recommended. If the patient urgently needs to have a baby, regular and close follow-up can also be performed after cone excision.

Carcinoma in situ: Generally, most people advocate total hysterectomy with preservation of both ovaries; some also advocate simultaneous removal of the vagina. In recent years, laser treatment has been used in China and abroad for patients with 1 cm or more. However, close follow-up is required after treatment.

Microscopic early invasive cancer: generally, extended total hysterectomy and 1-cm vaginal tissue are recommended because the possibility of lymph node metastasis of microscopic early invasive cancer is extremely small, so there is no need to eliminate pelvic lymphatic tissue.

Invasive cancer: The treatment method should be based on the clinical stage, age, general condition and equipment conditions. Common treatment methods include radiosurgery and chemotherapy. Generally speaking, radiotherapy is suitable for patients at all stages; the surgical effect of stage Ib to IIa is similar to that of radiotherapy. Cervical adenocarcinoma is less sensitive to radiotherapy and should be treated with surgical resection plus radiotherapy.

2. Surgical treatment

The use of extensive hysterectomy and pelvic lymph node elimination includes the entire uterus, bilateral appendages, upper vagina, paravaginal tissue, and pelvic lymph nodes. The operation requires thorough safety, strict control of indications, and prevention of complications.

3. Surgical complications and their treatment

Surgical complications include intraoperative bleeding, postoperative pelvic infection, lymphocele, retention, urinary tract infection, and ureterovaginal fistula. Treatment of surgical complications In recent years, the incidence of the above complications has been significantly reduced due to the improvement of surgical methods and anesthesia techniques, the use of preventive antibiotics, and the use of extraperitoneal negative pressure drainage after surgery.

4. Radiation therapy

It is the first choice treatment for cervical cancer and can be applied to all stages of cervical cancer. The radiation range includes the cervix and the affected vagina, uterine body, parametrial tissue and pelvic lymph nodes. The irradiation method generally adopts a combination of internal and external irradiation, mainly targeting the primary lesion of the cervix and its adjacent areas, including the uterine body, upper vagina and its adjacent parametrial tissue.

So far, cervical cancer is insensitive to most anti-cancer drugs, and the effectiveness of chemotherapy does not exceed %. Advanced patients can adopt comprehensive treatments such as chemotherapy and radiotherapy. Local injection of chemotherapy drugs.
