Commenting on the findings at the press briefing, which he moderated, Charles Staley, MD, from Emory University, in Atlanta, Georgia, said that transplantation has become the favored treatment for liver cancer because of the high rate of recurrence."Even if you cut out the first tumor, a second tumor appears within about 6 to 7 months," he said, adding that "the liver appears to be defective in these patients, and the best option is to remove it completely."

引言人乔治亚州亚特兰大Emory大学Charles Staley医师于发表会中简短表示，因为肝癌的再发率很高，移植已经成为肝癌偏好的治疗方式；即使你切除第一肿瘤，第二个肿瘤会在大约6~7个月内出现，他表示，这些病患的肝脏显然是有缺陷的，最好的选择是完全切除它。

Results 10 cases of single tumor,2 cases of double tumors in one kidney; one of them is mergering subcapsular hematoma,and the other is mergering subcapsular and retroperitoneal.

结果：单发肿瘤10例，单侧肾脏2个肿瘤2例，合并肾包膜下血肿4例，合并肾包膜下及腹膜后血肿1例。ct表现为低、等、高混杂密度病灶，增强扫描低密度、等密度病灶可有不同程度的增强，高密度病灶不增强。

Results Arc-needle injection 131I-iodinated oil in SMMC-7721 hepatoma at subcutis could increase rat's survival time, the body weight kept less descent, the lumps necrosed wholely.

结果 直形针给药组大鼠在注射后2周多数表现为体重下降，肿瘤增大，最后都死于全身耗竭；而弧形针组大鼠体重相对稳定，肿瘤组织表现为均匀坏死，缓慢崩溃，动物存活期明显比前者长。

METHODS: Thirty two children suffering from fourth ventricular tumors were admitted to our hospital and underwent removal of tumor by midline suboccipital approach under microscope.

在 1 996 0 8/ 2 0 0 3 0 7入我院的儿童第四脑室肿瘤患者 32例，显微镜下采用后颅窝枕下正中入路切除肿瘤。

Methods: 27 patients with large acoustic neurormas were operated via suboccipital retrosigmoid approach,intraoperative EMG monitoring was used to protect facial nerve,and its function evaluated.

对27例大型听神经瘤（直径＞3cm）均采用枕下乙状窦后入路，手术均在面神经电生理监测下进行，显微外科切除肿瘤，肿瘤切除后对面神经功能进行评价。

AIM: To study the affinity with tumor cells through series of N-octyl-N'-succinyl chitosan synthesized by using different molecular weight of chitosan.

目的：以不同分子质量的壳聚糖为原料合成系列的N－正辛基－N'-琥珀酰基壳聚糖，考察其与肿瘤细胞的亲和性，为其作为抗肿瘤药物的靶向载体提供依据。

RESULTS: N-octyl-N'-succinyl chitosan possessed stronger affinity than control cell lines and growth inhibition with the four kinds of tumor cells.

结果：N-正辛基－N'-琥珀酰基壳聚糖对4种肿瘤细胞亲和性明显强于空白细胞株(P.01)，并具有一定的肿瘤抑制作用。

The different angle DSA can well display tumor-feeding arteries from different angles and detect small overlapped lesions which were overlapped on conventional images.As an important supplementary means,different angle DSA is of great help to improve the successful rate of super-selective catheterization.

结论不同角度DSA能够多方位清晰地显示迂曲走行的动脉和重叠隐匿的较小的肿瘤病灶，显著提高小病灶检出率，提高超选择性插管的成功率和降低肝脏肿瘤的漏诊率，是一种重要的补充检查手段，有着重要的临床意义。

EphB2 may play suppressive role in carcinogenesis and progression of colon carcinoma.

EphB2对于肿瘤的生长可能起抑制作用，EphB2表达的减少可能促进了肿瘤的形成和演进。

It is becoming more clear that tumor progression is not exclusively regulated by oncogene and tumor suppressor gene pathways.

肿瘤的演进是一个复杂的多步骤的过程，包括正常细胞的恶性转化、肿瘤的生长、侵袭和转移。
