放射治疗的

Radiotherapy is one of major clinical methods in treatment of most tumors.

放射治疗是肿瘤治疗主要手段之一，资料显示有70%的肿瘤患者需行放射治疗。

Poor appetite and bone marrow suppression were observed one week after the craniospinal radiation, and the radiation therapy was ceased. Spinal magnetic resonance imaging showed no spinal matastasis. White blood and platelet counts gradually increased. Subsequently, brain radiation was initiated. The patient currently can walk with good endurance and without device.

中断脑部脊髓放射治疗期间脊髓之核磁共振检查结果无脊髓之转移，白血球及血小板数目已有回升，所以重新开始脑部放射治疗而不再照射脊髓的部分，减少骨髓抑制的并发症；个案食欲不振的现象改善，且口语表达、步行及耐力亦进步中，并於脑部放射治疗结束后出院，改为门诊追踪。

Both IMRT and conventional radiotherapy were planned for every patient. After comparing the radiation dose and volume to the heart and lung, and other dosimetric parameters, we then decided which technique to use for individual patient.

我们针对每个案例同时使用强度调控放射治疗及传统放射治疗做电脑计画，在比较心脏及肺脏的放射剂量、照射体积，和其他剂量分析参数后，再决定选用哪一套治疗计画做实际的临床治疗。

Management. Treatment of manifestations: Early diagnosis and treatment of RB and RB-related tumors can reduce morbidity and increase longevity; care is best provided by specialists from ophthalmology, pediatric ophthalmology, radiation oncology, oncology; treatment options depend on tumor stage, number of tumor foci (unifocal, unilateral multifocal, or bilateral), localization and size of the tumor within the eye, presence of vitreous seeding, and age of the child; treatment options may include enucleation, cryotherapy, photocoagulation, photochemistry, external beam radiation therapy, and radiation therapy using episcleral plaques; newer options include systemic chemotherapy combined with or followed by local therapy.

处理。 表征的治疗： RB 和 RB 相关肿瘤的早期诊断和治疗能减轻病状、延长存活时间；护理最好由眼科学、小儿眼科学、肿瘤学和放射肿瘤学等方面的专业医师来提供；治疗方案的选择取决于肿瘤阶段、病灶数量（单病灶、单侧多病灶或双侧病灶）、眼内肿瘤的位置和大小、玻璃体散布的存在与否以及患儿的年龄；治疗选项可能包括摘出术、冷冻疗法、光凝固术、光化学法、外照射放疗和用巩膜外斑块进行的放射治疗；新的治疗选项包括与局部治疗结合的或先行的系统化学疗法。

［Purpose］ To investigate the relationship between radiation encephalopathy after radiation for nasopharyngeal carcinoma and radiotherapeutic field design.

放射性脑病（radiation encephalopathy，REP）是一种严重的放射治疗并发症，常见于头颈部恶性肿瘤放射治疗后，尤其多见于鼻咽癌治疗后。

Methods from Sept 2000 to March, 2002 516 patients with body tumor were therapied. The radiotherapeutic plan and set dosage distribution had been worked out on the basis of the carcinoma position, clinical target volume, patient health condition, and therapeutic aim. The isodosage curve was 50-90%. The fractional doses was 300-900cgy. The therapy had been repeated for 5-9 times for one patient, every two days one time. Results the patients were followed up 3 to 15 months after therapy.

采用OUR-QGD立体定向伽玛射线体部放射治疗系统治疗肿瘤患者516例，根据肿瘤的部位、临床靶体积大小、分类与治疗目的，如临床根治或姑息治疗，以及肿瘤周围的组织与器官、病人的身体状况、既往治疗情况、有无淋巴结转移等制定放射治疗计划及调整剂量分布， PTV覆盖95%以上CTV，等剂量曲线50~90%，中位值62.2%。

BACKGROUND Young female adult and adolescent cancer patients facing life-preserving but fertility-threatening chemo- or radiation-therapy are increasingly seeking options to protect their reproductive potential.

背景年轻的成年女性和青少年癌症患者在行化疗或放射治疗是面临延长寿命（化疗或放射治疗可以延长寿命）和生育威胁（化疗或放射治疗威胁生育率）的两难境界，越来越多的患者去寻求保护她们的生殖潜力的可能办法。

Along progresses of radiotherapy and related technologies in radiobiology, the radiotherapy is more widely introduced into treatment of other brain disease such as Parkinsons disease. However, there are still lack of data on the biological effect and injury of radiotherapy on the brain normal tissue and neurons.

随着医学影像学、电子计算机技术、放射物理和放射生物学的发展和进步，立体定向放射治疗技术也推广应用于多种疾病，如脑良性疾病如癫痫、帕金森病的X-刀治疗呈逐年增长趋势，并取得良好效果。

This includes: clinical radiotherapy, combined modality treatment, experimental work in radiobiology, chemobiology, hyperthermia and tumour biology, as well as physical aspects relevant to oncology, particularly in the field of imaging, dosimetry and radiation therapy planning.

它刊登于放射肿瘤学感兴趣领域，这些领域包括：临床放射治疗学，肿瘤多学科治疗方案，放射生物学的实验性研究，化学生物学，热疗学和肿瘤生物学，以及与肿瘤有关的物理学领域，尤其是影像学，剂量学和放射治疗计划。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
