1. As long as there are metastasis in pelvic lymph nodes or para-abdominal aortic lymph nodes, or stage IIb (tumor parametrial infiltration) or above, or positive cut edge, radiotherapy is needed. Not only radiotherapy is needed, but also chemotherapy is recommended, and cisplatin alone can be used for chemotherapy. 2. Although there is no lymph node metastasis, as long as the tumor is >4cm (IB2, IIA2), postoperative radiotherapy is also needed. 3.Even if there is no lymph node metastasis, but combined with the following high-risk factors: deep interstitial infiltration, or lymphatic vascular interstitial infiltration, supplemental pelvic radiotherapy (without chemotherapy) is required. Observation is also an option. 4.For IA2, IB1 or IIA1 stage with negative lymph nodes and no high-risk factors, postoperative radiotherapy is not required. 5.If distant metastases are found after surgery, chemotherapy is the main treatment, as well as individualized treatment. It should be noted that for patients with stage IB2 to IVA, the expert consensus in recent years prefers radiotherapy to combined surgery and radiotherapy because the efficacy of both is basically the same, but the latter has too many complications and side effects.
