In the advanced stage of the tumor, the doctor said that surgery was needed.

Surgery is the first choice for the treatment of most malignant tumors, which is irreplaceable by radiotherapy and chemotherapy. It can eliminate tumor cells in vivo as much as possible, reduce the harm caused by tumor metabolism and secretion to the body, such as immunosuppression, internal environment disorder, abnormal organ function, etc., provide favorable conditions for postoperative radiotherapy and chemotherapy, minimize drug-resistant cells and hypoxic cells, and significantly increase the curative effect of radiotherapy and chemotherapy. However, patients with advanced tumors must be given postoperative radiotherapy or chemotherapy (different choices are made according to different situations), because the maximum tumor clearance only refers to the masses and areas that may be invaded by naked eyes, and a small number of tumor "cells" cannot be removed by surgery (except for early tumors), so the tumor load of the body is obviously reduced after surgery, and the tumor growth pressure is reduced, which will accelerate the division and growth of the remaining cells, thus losing the significance of surgery.

Of course, generally speaking, the first choice for advanced metastatic malignant tumors is not surgery, but systemic chemotherapy. I understand that when you say inguinal tumor, you mean metastatic lymph nodes. If the curative effect evaluation after three cycles of chemotherapy can make inguinal lymph nodes disappear completely, surgery can be considered, because as long as there is metastasis, it is not meaningless. This condition is neither organ metastasis nor bone metastasis. Of course, but before the operation, it is necessary to improve the comprehensive examination to make sure that there are no metastatic lesions in other parts, and whether the patient's physique can tolerate the operation remains to be determined.
