If pelvic lymph node metastasis is found in postoperative pathological analysis of cervical cancer, postoperative radiotherapy can be taken as a simultaneous or sequential treatment measure, and the patient can be closely followed up to monitor the change of condition after treatment. Pelvic lymph node metastasis is found in postoperative cervical cancer, which indicates that the clinical staging is stage III. Due to the late staging, in order to improve the clinical cure rate, it is necessary to take radical surgery combined with radiotherapy and chemotherapy as treatment measures. If the patient’s physical condition is better, radiotherapy and chemotherapy are generally taken at the same time, and chemotherapy is generally chosen as the combination of paclitaxel and carboplatin or cisplatin. If the patient’s physical condition is slightly worse, the patient can take local adjuvant radiotherapy first, and then systemic adjuvant chemotherapy for sequential treatment program, chemotherapy drugs mostly choose paclitaxel, carboplatin or cisplatin and so on. It is recommended that patients choose the appropriate treatment method under the guidance of doctors to prolong the survival period.
