Lymph node recurrence, if there is no distant metastasis from other organs, it is recommended to: 1. Continue chemotherapy and radiotherapy: Due to the recurrence in a short period of time, consider the possibility of tumor resistance, and change the regimen when chemotherapy is needed. You can choose gemcitabine alone or combined with platinum-based regimen, and you can also choose vincristine combined with platinum-based (cisplatin, oxaliplatin, etc.), vincristine combined with capecitabine, or even capecitabine or gemcitabine combined with paclitaxel. Her2 testing is also feasible, such as immunohistochemistry Her2(+++) or Fisher test Her2(+), and Herceptin treatment can also be applied. 2, surgery: this depends on the scope of lymph node contouring at the first surgery, if the first surgery lymph node contouring to the first, or second station, can also expand the scope of contouring lymph nodes to the second and third station. If the lymph nodes are already contoured to the third station in the first surgery, the local enlarged lymph nodes can also be removed. However, note that since metastatic enlarged lymph nodes can be used as a touchstone and monitoring target for chemotherapy, and can reflect the sensitivity of the tumor to the drug, I personally usually recommend patients to have chemotherapy first, and evaluate the effect of chemotherapy at the end of each or two chemotherapy cycles, and change the regimen if it is ineffective, or continue with it if it is effective. Then radiation therapy and surgery will be performed to enhance the efficacy.
