Brain injury in 7 patients are in the stars Securinega ship, who received twenty courses of treatment in 4, double ear before the field exposure, including the nasopharynx, skull base (including the temporal lobe at the bottom), the total of the smell in the DTi10 ~ I40Gy; 3 down to a single course of treatment, the total DT70 ~ 75Gy. 7 patients were alive, the quality of life index score according to our health, receive two courses of treatment in 4 cases of Phi 8O points in those 3 sides, 9O minutes in 1 case; a single course of radiotherapy in 3 cases in 00 minutes in 1 side. i00 sub 2 sides. 2 sides of spinal cord injury patients were TN. M0 and TtNM0 combined with face, neck and neck increases the vertical field irradiation field, the total irradiation neck DTS0 - 85Gy (spinal cord more than DT50Gy), respectively, died within 3 years of treatment refuse blood metastasis received two courses of treatment of brain injury in the second occurred 2 years after the treatment process, a single course of treatment occurred in 4 to 6 years. Spinal cord injury occurred within 1 year after treatment. Main clinical manifestations of brain injury in order to save the spirit of symptoms, forgetfulness, of sowing the coup, stay on a backing, or talkative, irrelevant answers, brief loss of consciousness or thinking stops (known to take leaves really lame), smell, taste abnormalities, while those light pox only occasional or frequent dizziness. 2 cases of spinal cord injury manifested as limb and trunk sensory or motor abnormalities, but there was a paraplegic symptoms. Radiation damage caused by cT, MRl examination confirmed. 2 discussions radiotherapy in head and neck cancer, central nervous system radiation sprain is more serious complications, the rate was 1 SCI imitation of which is I (203), brain injury 3.4 (7 / 203), and 9 cases were confirmed by this paper, CT and or MRI, 7 of the bottom side of leaves Villa abnormal changes in brain tissue (bilateral in 4, unilateral 3 down), showed the limitations of low density (or low signal lead). Saw enhanced or enhancement capsule) 7.6 of changes due to mild injury is similar to nerve cells in demyelination changes in the temporal lobe in two cases CT scan can rule out brain metastasis, recognized as a side line MRJ brain radiation check injury. Therefore, radiation damage of the central nervous system MRI is superior Haka CT, the literature has been reported Yat, and described its mechanism of radiation damage of the central nervous system depends on the dose received, so the head and neck radiation j {f} Gan to the spinal cord should be fully assessed, the amount of brain tissue affected. Tired of shooting the neck line should be a reasonable choice line of high-energy x ray and an appropriate mix of electronics, especially in the face, neck joint field irradiation (including spinal cord), or the barrier between the neck tangential irradiation of the spinal cord does not block the case of lead protection, radiation DT ~ IOGy increase the amount of the neck after irradiation should be cautious. When the amount of neck irradiation and electron vertical line energy should not exceed 12Mev, ring lead by the middle of the neck block of wild tangent l Department of dosage, so that the amount of spinal cord do not exceed DT45Gy · 25 Di a, 35d, occupational exposure to nasopharyngeal ear Maeno and the base of the skull, the radiation field should be limited to the skull base on the border line (outside the outer ears are ~ midpoints) on the i, 5cln less on the mere recurrence of the second leg of nasopharyngeal irradiation field when double-ear solution should not exceed the upper bound of the skull base line. However, some primary tumors saddle late lesions (such as T, T.) in order to control the tumor and improve the radiation dose, high dose irradiation of skull base is inevitable, is also the possibility of brain damage among the total of the original material Ke stripping should be Without prejudice to the premise of cancer treatment should be to minimize the brain, spinal cord affected the most, while in the control tumors, without reducing the quality of life.
