Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): My sister is 52 years old, suffering from invasive ductal carcinoma early stage II, and has been doing chemotherapy for 3 courses after surgery, and now her white blood cells are dropping very low, now down to 1100. Do I need to continue the granulocyte stimulating factor medication in this case? 2. Is it okay if I insist on taking shagganol after the next chemotherapy and stop taking granulocyte stimulating factor? 3. Is it okay if I take oral shark glycol and combine it with granulocyte stimulating factor injection? 1. The degree of leukocyte decline is related to the drugs and doses used, such as epirubicin, paclitaxel and other chemotherapy drugs with strong myelosuppressive effects. There is also a relationship with the patient’s physical condition. 2, if the white blood cells are too low (such as below 2000/ml), you should inject granulocyte colony-stimulating factor. The reason for the lower the leukocyte count is that the patient is still in the myelosuppression period, which may also be related to the lack of food and nutrition during this period. 3, shark glycol can be used, but the effect is certainly not as good as granulocyte colony-stimulating factor. 4.During the chemotherapy drug period, the diet should be light; during the interval of chemotherapy, after the digestive tract reaction is gradually reduced, the nutrition should be strengthened, the recipes should be comprehensive, and the intake of animal protein should be increased appropriately to help the recovery of blood cells. 5, you can take some Chinese medicine at the same time, such as Ginseng Astragalus eleven granules or compound Aconite syrup, etc. I personally feel that the effect is better than some western oral raw white medicine.
