放射治疗

There are four major types of cancer treatment: surgery, radiation therapy, chemotherapy, and immunotherapy.

有四种主要的癌症治疗类型：外科、放射治疗、化学治疗和免疫治疗。

Results Contrast CT or MRI showed prominent irregular circular or nodular enhancement in 14 of 16 cases (64%),can not distinguished from postopertative changes, radioinjury, tumor residue or recurrence.Among them, 9 cases showed tumor residue or recurrence based on significantly increased FDG uptake, 5 were confirmed by pathologic study. The other 5 cases of cerebral necrosis and 2 cases with postoperative cerebral malacia demonstrated FDG uptake defects.

结果 16例中87.5%(14例)CT和MRI表现不规则环形或结节状明显强化，不能准确作出手术后改变和放射治疗后脑损伤、残存肿瘤或肿瘤复发的诊断；其中9例残存肿瘤或肿瘤复发病灶18F-FDG PET影像表现为葡萄糖代谢明显增高，有5例得到手术病理证实；另5例术后放射治疗后脑损伤患者和2例术后软化灶18F-FDG PET影像均显示局部病变区为放射性分布缺损或明显低下。

Another study demonstrated that women who take alkylglycerols prophylactically starting eight days before the beginning of radiation therapy have lower mortality rates and greater survival than women who just take them during the course of radiation therapy.

另一研究表明，妇女在接受放射治疗8天前定期服用alkylglycerols，比仅仅在放射治疗过程中服用alkylglycerols的妇女存活率大大提高，死亡率显著降低。

Objective To determine the scattering and density effects of intrauterine contraceptive ring on pelvic radiotherapeutic dosage distribution.

目的 测量元宫型金属宫腔内节育环对放射治疗引起的密度效应及次级射线引起的散射效应对放射治疗剂量分布的影响。

In this article, the radiosensitization and development of radiotherapeutic technology are reviewed. Recent progress in reducing the radiation-induced hepatic injury is also summarized.

本文主要从肝癌放疗敏感性、放疗技术的发展等方面对PHC的放射治疗作一综述，旨在说明PHC的放射治疗在减少放射性肝损伤等方以取得了可喜的成绩，且仍有较大发展空间。

Purpose To evaluate the effect of stereotactic radiotherapy in the treatment of brain metastasis.

目的 探讨 X线立体定向放射治疗在脑转移瘤常规放射治疗中的作用。

None of the other potential prognostic factors evaluated (including patient age, gender, tumor grade, tumor location, subtotal resection, presence or absence of cranial nerve palsies, total dose, 3D conformal radiotherapy, duration of symptoms, or radiological response) were associated with patient overall survival in multivariate analysis.

以多变数分析评估其他一些可能的预后因子（包括病患年龄、性别、肿瘤的分化程度、肿瘤位置、是否接受手术切除、有无脑神经麻痹、放射治疗总剂量、三度空间顺形放射治疗、症状的持续时间、或影像学上肿瘤是否变大）均不影响病患存活率。

When conventional radiotherapy of nasopharyngeal carcinoma is practiced with the facio-neck field and inferior-neck-supraclavicular field by the half-beam technique, it is confirmed that the dose-overlap region at the match-plane is smaller than the whole-beam technique.

背景 近年来放射治疗剂量学研究表明，鼻咽癌应用面颈联合野与下颈切线野放射治疗时，与全束照射技术相比，半束照射技术的照射野衔接处剂量重叠区较小，理论上可能降低放射性神经损伤的发生率。

At least it is a good thing that the Gereral Dr. in the Radiation Dep. said to me that the only stuff remain in my chest should be nothing more than ineffective tissue, according to the cat scan.

九月初去做检查，当放射治疗科的主任跟我说：依照多年的经验，放射治疗后，断层扫描显示的肿瘤现在剩下的应该都只是无害的组织了。

But in several aspects,such as targets delineation,radiophysics,radiobiology it also has many problems that deserves study furthermore.

但在调强放射治疗的靶区勾画、放射物理、放射生物学方面还存在许多问题，值得进一步研究。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
