Can recurrence of cervical precancerous lesions be treated?

Can cervical precancerous lesions be cured if they recur? Cervical cancer is a cancerous change in the female cervix. Cervical cancer can be cured through active treatment in the early stages. The main treatment methods include surgery, radiotherapy, chemotherapy, and Chinese medicine. In the early stages, several combined treatments can be used. 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 cervical cancer and can be applied to all stages of cervical cancer. 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 (point "A"). External irradiation is mainly aimed at the area where the pelvic lymph nodes are distributed (point "B"). The internal radiation source uses intracavitary radium (Ra) or 137cesium (137Cs), which is mainly aimed at the primary lesion of the cervix. The external radiation source uses 60 cobalt (60Co), which is mainly aimed at metastatic lesions outside the primary lesion, including the pelvic lymph node drainage area. The dose is generally 60Gy. At present, it is advocated to perform internal irradiation first for early cervical cancer. For advanced cancer, especially those with huge local tumors, active bleeding, or concomitant infection, it is appropriate to perform external irradiation first.

4. Chemotherapy

So far, cervical cancer is not sensitive to most anticancer drugs, and the effectiveness of chemotherapy does not exceed 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.

Cervical cancer is the most common cancer of the female genitals. Early detection has great hope for cure, so early detection and early treatment are necessary. Care and treatment should also be done after cervical cancer surgery. Pay attention to hygiene to keep the vulva clean, and eat more high-vitamin, high-protein, and easily digestible foods. Cervical cancer patients generally have a poor physical condition after regular treatment, so in order to quickly recover from fatigue, you must ensure adequate rest. This is conducive to physical recovery.
