swimming pool pain loss! In the early hours of July 19th, Xu Guoyi, a meritorious coach who has trained many Olympic champions and world champions such as Ye Shiwen and Xu Jiayu, died of a malignant brain tumor at the age of 50.
media previously reported that at the end of 2015, 45-year-old Xu Guoyi coach was found to have a malignant brain tumor, pathology reached IV level.
"brain glioma is generally divided into four levels according to pathological examination. Wang Jin, chief neurosurgery physician at Tsinghua Changxuan Hospital in Beijing, told the Health Times that among all brain tumors, the highest incidence, the most complex treatment and difficult to cure is glioma, the annual incidence rate of 5/100,000 to 8/100,000. Brain gliomas include astrocytes (WHO II/III), protrusion cell tumors (WHO II/III), glioblastomas (WHO IV) and child-related diffuse gliomas. Clinically used to refer to world health organization (WHO) grade II gliomas as low-grade gliomas, who III./IV as high-level gliomas. Director wang Jin
introduced: "Brain tumor is not like breast cancer, lung cancer will be transferred to other parts of the body, but because the brain tumor and normal brain tissue have no boundary, so, it grows very fast, reproduces very fast, patients will soon appear headache, epilepsy and other symptoms, cerebral edema is also very serious!" The most serious glioma is the grade IV glioblastoma. Low-level gliomas (I, II) grow slowly and have long survival.
high-level glioma scant, the higher the level of the tumor, the higher the malignant degree, the shorter the survival. Senator McCann of Arizona, as well as President Kennedy's brother, Senator Edward Kennedy of Massachusetts, both died of glioma, both of whom died after undergoing surgery and painful release and chemotherapy after being diagnosed with malignant brain tumors, glioblastomas. Glioma, the most common primary tumor in the skull, has also attracted renewed public attention.
"the survival of patients with glioma is related to the age of patients, the patient's functional status, tumor size, pathological classification, surgery, etc., the average survival of glioblastoma patients is generally about 12-13 months. "The older the patient, the worse the preoperative condition, the worse the patient's prognosis, " Said Wang.
at present, the treatment of brain tumors mainly through surgical excision, auxiliary radiation therapy and chemotherapy, "generally is the first part of the tumor removal, if the tumor in the brain position is too deep or located in an important functional area, surgical excision may cause paraplegia, aphasia and other serious consequences, at this time may consider a biopsy to confirm, and then radiation, chemotherapy. But the drug of glioma chemotherapy is much less than breast cancer and lung cancer. Because glioma will be immersed in peripheral brain tissue, so the glioma after surgery will be 100 percent relapse, glioma after recurrence of treatment is still a medical problem.
therefore, Director Wang Jin reminded patients, with headaches, new epilepsy, side of the body appear seventy-day sensation or motor dysfunction and other symptoms, must not "hard resistance"! "The tumor can be difficult to deal with when it is very large, and it must be diagnosed early and treated early."
