At this time, the tumor can be reduced by preoperative chemotherapy, so that the originally inoperable or more difficult surgery can be converted into operable. This is a situation.

　　 There is also a case where the operation can be performed directly from the beginning, but in order to make the operation better, the tumor is reduced by preoperative chemotherapy, the operation is better, and the surgical complications are less, In short, the size of the tumor is reduced by preoperative chemotherapy, and the control or elimination of small or occult distant metastases is to improve the surgical resection rate and improve the long-term survival rate after surgery (ie, increase the probability of cure).

　　 Doctors recommend preoperative chemotherapy, which certainly has his basis. On the contrary, many doctors do not understand preoperative chemotherapy, or are too lazy to preoperative chemotherapy. The consequence of reluctant surgery is that it may reduce the long-term survival rate. Chinese superstitious surgery always thinks that if you have cancer, you must seize the time for surgery, and don''t procrastinate for a moment. You also have to do very reluctant surgery, thinking that if you cut the tumor, everything will be fine.
