"Learning more about the way a specific type of cancer deelops, and what proteins it produces as it grows, helps us find better ways to treat that cancer," said Dr. Lai, who is a cancer researcher at Mayo Clinic with background as an otolaryngologist."With nasopharyngeal cancer, we think this new enzyme may help sole the puzzle."

Breast cancer is the fourth leading cause of cancer death for Taiwanese women. X-ray mammography is currently the most effective method for an early diagnosis of the breast cancer. The existence of spicules is one of most important visual signs for breast cancer diagnosis. Spiculation is a stellate distortion caused by the intrusion of breast cancer into surrounding tissue. In general, malignant tumors appear with rough and complex boundaries or contours, whereas benign masses present smooth, round, or oval contours.In this paper, we present a technique to detect the contours of spiculated lesions from the regions of interest in a mammographic image.

中文摘要乳癌是是我国妇癌症死亡主因的第四位，乳癌诊断程序中，乳房X光摄影为临床上医生诊断乳癌的利器，在诊断乳房摄影肿瘤的影像时，可用特徵决定为良性或恶性肿瘤，良性肿瘤通常会呈现圆滑的特徵，而恶性肿瘤则呈现星状或不规则不平滑特徵，这种星状或不规则不平滑特徵组织，称为星状物肿瘤，指的是肿瘤周围的乳腺组织，因星状物往外侵犯的关系造成的变形，星状物的存在是恶性肿瘤判断的依据。

Objective To analyze the CT and MRI manifestations of oral carcinoma,and to evaluate the value of imaging technologies in the diagnosis of oral carcinoma,thus to explore the most reasonable imaging method Methods 46 cases with oral carcinoma,proved by surgery and pathology （2 lip tumors,8 carcinomas of the gingival ridge,5 carcinomas of the buccal mucosa,24 tongue carcinomas,5 carcinomas of the floor of the mouth,2 tumors of the hard palate）,were analysed retrospectively32 cases were examined with CT and 14 cases with MRIImaging presentations were compared with surgery and pathology Results Of the 46 cases with oral carcinoma,22 were ulcerative lesion of infiltrative growth,24 were masslike lesion of extruded trowthOf the 32 cases examined with CT scan,27 were detected,5 were missed,the 4 missed cases were confirmed to be superficial ulcers by surgery and pathologyOf the 10 cases with bone destruction examined with CT scan,8 were manifested,2 were missedAnd of the 14 cases with MRI scan,all 14 were detected Conclusion CT and MRI scan are valuable for diagnosis of oral carcinomasThey can manifest the morphology and size of primary tumor,contiguous structures,bone invasion and cervical lymph node metastasisMRI is the optimal imaging method for superficial ulcerative lesion of infiltratibe growth

徐 锋，罗德红，唐威，欧阳汉，周纯武目的分析口腔癌的CT及MRI表现，评价影像检查在口腔癌诊断中的应用价值，探索合理的影像学检查方法。方法回顾性分析经手术及病理证实的口腔癌46例（唇癌2例，牙龈癌8例，颊黏膜癌5例，舌癌24例，口底癌5例，硬腭癌2例），其中32例行CT扫描，14例行MRI扫描，将影像表现与手术所见及病理结果进行对照分析。结果 46例口腔癌中，呈浸润性生长的溃疡型病变22例，外生性生长的肿物型病变24例。CT扫描32例，明确显示病变27例，遗漏病变5例，其中4例为表浅溃疡型病变。CT扫描病例中，10例有骨质侵犯，CT扫描准确评价8例，遗漏2例。MRI扫描14例，均准确评价肿瘤及其与周围结构的关系。结论 CT、MRI对口腔癌原发肿瘤的形态、大小、周围结构侵犯、颈部淋巴结转移的评价有重要价值。对于较小及呈浸润性生长的表浅溃疡型肿瘤，CT扫描尤其是CT平扫难以准确显示，应首选MRI。

Abstract］ objective to evaluate the distinctive clinical value of magnetic resonance urographymru）in the diagnosis of primary ureteral carcinoma.methods to compare the accuracy of diagnosis of mru with ultrasonography,urography,retrograde ureteropyelography and ct,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had mru examinations.the original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.results mru could clearly show the obstructive location of ureter.with regard to the ureteral carcinoma,accuracy of the location diagnosis was 100%.mru was superior to ulstrasonography,kub+ivp,ureteropyelography and ct we used to apply.conclusion comparing with other diagnostic imaging facilities,it has an important value in highly efficient,accurate location,safe,noninvasive and so on with mru,which can be used to show the features of primary ureteral carcinoma and has a wider scope of clinical application.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值。方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、ct(19例）的确诊率相比较。结果 mru能清晰显示输尿管的梗阻部位，定位诊断准确率为100%，梗阻病因确诊率高于b超、泌尿系造影、逆行造影和ct检查。结论与其他影像诊断方法相比较，磁共振水成像在显示原发性输尿管肿瘤特征方面具有效率高、定位准确和安全无创等重要价值，而且有更广泛的临床应用范围。

本文首先详细介绍了奇点展开法的背景及其原理，接着应用我们开发的时域有限差分仿真程序得到早期乳房肿瘤的微波散射信号，采用Prony极点提取方法对肿瘤的微波散射信号进行肿瘤特征极点的提取。

Statistical data of VEGF grading scores showed that its expression was not significantly related to the size and location of glioma, sex, and age of patients, but closely related to the glioma gradings. The expression of TF was positively correlated with that of VEGF, suggesting that TF might participate in the anigogenesis of gliomas, and provide proper environment for the growth of gliomas through its coagulant effect.

根据VEGF分级计数统计学分析，显示VEGF表达与肿瘤的大小、部位及患者性别、发病年龄等临床因素无显著相关性，而与肿瘤的组织学分级密切相关。3、胶质细胞瘤中TF与VEGF的表达正相关，TF可能参与了肿瘤血管的生成过程，并通过其促凝血活性作用为胶质瘤的生长创造适宜的内环境。
