It is possible that radiotherapy for lymphatic metastasis of cervical cancer will be able to control the disease. When cervical cancer has developed lymphatic metastasis, the chance of cure will be greatly reduced and the prognosis is not very good. In this case, the treatment effect of surgery will not be very good, so radiotherapy is generally recommended to control the condition first. Once cervical cancer lymph node metastasis occurs, it includes early cervical cancer lymph node metastasis and advanced cervical cancer lymph node metastasis. If it belongs to advanced cervical cancer with lymph node metastasis, the common treatment method is synchronized radiotherapy. Through laparoscopic or extraperitoneal route, the enlarged lymph nodes are removed, and after clear diagnosis by pathological examination, synchronous radiotherapy is given. Its treatment is mainly based on synchronized radiotherapy, combined with immunotherapy and molecular targeted therapy, etc. Even if it spreads to lymph nodes, its 5-year survival rate is probably more than 50%. Lymphatic metastasis of cervical cancer can be controlled by radiotherapy in regular hospitals, and many neck lumps and enlarged pelvic lymph nodes can be significantly reduced or even disappeared after radiotherapy, and attention should be paid to the need of regular review during radiotherapy.
