  early pancreatic
Pdx-1, an important transcription factor highlighting in the early pancreatic development, islet functions and pancreatic disorders, needs to be more investigated in zebrafish, and siRNA is still seldom applied in zebrafish embryo-related research.
      
Only when we understand early pancreatic neoplasms will be able to detect tumors that are curable with surgical resection.
      
Recently detection of 18q deletions (at the DPC4 locus) in pancreatic secretions from early pancreatic cancers was also reported.
      
These advances raise the possibility that within well defined at risk groups it will be possible to use a combined set of molecular markers to screen clinical samples and detect early pancreatic cancer or even premalignant lesions.
      
The homeodomain protein PDX-1, an insulin gene transcription factor, is uniformly expressed in the early pancreatic bud, and null mutation of PDX-1 in mice results in a failure of the pancreatic bud to grow and differentiate.

This paper summerizes 93 cases of pancreas carcinoma demonstrated by CT scan and pathologtcal examination, emphasizing the CT diagnosis of the small pancreas, carcinoma less than 3cm. It showed that the varistion of the contour and the substantial appearance of the pancreas. the irregular and mildly increasing or the little local elevation of the pancreas head, the variation of the processus uncinatus as changed roundly and swellingly, the distention of the pancreas duct and the bile duct were the important sings of the early pancreas carcinoma. It indicates that the dynamic thin CT scan is an effective method to discover and to diagnose the early pancreas carcinoma. The assured rate is 83. 3%.

本文总结经CT扫描及病理证实的胰腺癌93例,重点讨论直径≤3cm的小胰腺癌CT诊断。表明胰腺轮廓及实质形态变化,胰头不规则轻度增大或有小的局部隆起,钩突圆隆变形,胰管胆管扩张等是早期胰腺癌的重要征象。提示动态薄层扫描是胰腺癌早期发现和早期诊断的有效方法,其确诊率为83.3%。

Abstract The four aspects are discussed in this paper. (1) The present conditions of the management of pancreatic cancer. It is difficult to make early diagnosis of pancreatic cancer,the three fourth of clinical cases is in the advanced stage ( Ⅲ or Ⅳ stage). Surgical resection rate is about 20% ,5-years survival rate is about 10% in resectable patients. In the authors'hospital, surgical resection rate is 9. 1% in 473 cases,5-years survival rate is 7% (3/ 43) in resectable patients. (2) The causes of delayed...

Abstract The four aspects are discussed in this paper. (1) The present conditions of the management of pancreatic cancer. It is difficult to make early diagnosis of pancreatic cancer,the three fourth of clinical cases is in the advanced stage ( Ⅲ or Ⅳ stage). Surgical resection rate is about 20% ,5-years survival rate is about 10% in resectable patients. In the authors'hospital, surgical resection rate is 9. 1% in 473 cases,5-years survival rate is 7% (3/ 43) in resectable patients. (2) The causes of delayed diagnosis and treatment. The misdiagnosis rate is 40. 4% before patients were admitted, preoperative misdiagnosis is still 12. 6% in our 292 cases with pancreatic cancer. The causes of misdiagnosis include difficulty in differential diagnosis with chronic pancratitis and benign obstructive jaundice,the location of tumor (tumor is located in uncinate process of pancreas). 5 misdiagnosed cases are discussed in this section. (3) How to find early cases. The high risk group is the group more than the age of 40 complained of nonspecial gastrointestnal symptoms with the history of pancreatitis or diabetes. After the common gastrointestinal disorders are ruled out, pancreatic cancer should be suspected. (4) How to improve prognosis. Total pancreatectomy decrease the life of quality. It is suggested to perform proper extensive pancreatoduodenectomy, which includs division of pancreas at the left margin of abdominal aorta, division of bile duct at the level of common hepatic duct, division of uncinate process of pancreas closed to the left margin of superior mesenteric artery ,and removal of parapancreatic lymph nodes (en-block resection ). The classical pancreatoduodenectomy is not enough for radical resection of tumor.

本文由四部分组成。(1)胰腺癌诊断治疗现状:胰腺癌早期诊断困难,临床患者四分之三为Ⅲ、Ⅳ期患者,很少有Ⅰ期患者。手术切除率约在20%左右,切除后5年生存率约在10%左右。我院437例中手术切除率为9.1%,切除后5年生存率为7.0%(3/43)。(2)延误诊断和治疗的原因:我院292例胰腺癌中,来院前误诊率为40.4%,在我院术前误诊率仍达12.6%。误诊原因包括与慢性胰腺炎及良性梗阻性黄疸鉴别困难,以及肿瘤的部位等。(3)如何发现早期胰腺癌或小胰癌:首先应提高警惕,在高危人群中查找,即在40岁以上有胰腺癌诸多症状并有胰腺炎或糖尿病病史者中查找。在排除肝胆、胃肠和腹腔肿瘤等疾病后,要高度怀疑胰腺癌。(4)如何提高治疗效果:全胰切除降低生存质量,故目前多主张有条件者应行适当的扩大切除术。即在腹主动脉左缘切断胰腺,在肝总管水平切断胆管,紧靠肠系膜上动脉左缘切除钩突,并行胰周淋巴结廓清的整块切除。只行一般的胰十二指肠或胰体尾切除是不够的。

The CT features of 67 cases with pancreatic carcinoma proved pathologically were analyzed.The CT appearances of the pancreatic carcinoma were as following:Local enlargement of pancreas occurred in 50 patients(74.6%).Linear soft tissue densities extending into mesentery were found in 8 cases(11.9%)and isodense or homogeneous hypodense masses were seen in 41 cases(61.2%),According to the number of involved vessels,the order of frequency were as following:Inferior vena cava,superior mesenteric vein,superior mesenteric...

The CT features of 67 cases with pancreatic carcinoma proved pathologically were analyzed.The CT appearances of the pancreatic carcinoma were as following:Local enlargement of pancreas occurred in 50 patients(74.6%).Linear soft tissue densities extending into mesentery were found in 8 cases(11.9%)and isodense or homogeneous hypodense masses were seen in 41 cases(61.2%),According to the number of involved vessels,the order of frequency were as following:Inferior vena cava,superior mesenteric vein,superior mesenteric artery,aorta,etc.Enlarged spleens and secondary pseudocysts appeared in 15 and 11 cases respectively.Finally we discussed briefly the difficulties of the early diagnosis of pancreatic carcinoma,the CT features of the secondary pseudocysts and criteria of CT staging of pancreatic carcinoma.

分析了67例经手术及病理学证实的胰腺癌的CT征象。胰腺轮廓局限性增大50例(74.6%),8例(11.9%)显示向肠系膜侵犯的线条状影,等密度或均匀低密度病灶41例(61.2%)。受累血管以下腔静脉、肠系膜上动、静脉及腹主动脉为多(94.8%)。脾脏增大15例,继发假性囊肿11例。讨论了早期胰腺癌诊断的难点和可能性,总结了胰腺癌继发囊肿的CT特征,对胰腺癌手术切除性的CT标准进行了评估。
