Pancreatic invasion is a prognostic indicator after radical resection for carcinoma of the ampulla of Vater

Sixty-three patients who had undergone pancreatoduodenectomy for carcinoma of the ampulla of Vater were analyzed with respect to tumor extent and prognosis. The postoperative mortality rate was 3% and overall survival rates 3 and 5 years after surgery were 55% and 46%, respectively. pTNM stage did not reflect prognosis after resection in patients at stages 2 and 3, while pancreatic invasion and regional lymph node metastasis clearly reflected prognosis after resection. Of the 26 patients who had no pancreatic invasion, regional lymph node metastasis was seen in only 19%, whereas of the 37 patients with pancreatic invasion, 62% exhibited lymph node metastasis. These factors were significantly correlated (P<0.001). Pancreatic invasion appeared to be an indirect indicator of regional lymph node metastasis. We conclude that, to improve prognosis for patients with pancreatic invasion, extended resection including extended lymphadenectomy, is a preferable additional procedure.     

Endosonographic criteria for assessment of the depth of duodenal invasion in carcinoma of the papilla of Vater

Background: Imaging criteria by endosonography for assessment of the depth of duodenal invasion of carcinoma of the papilla of Vater (papilla carcinoma) have not been established. Methods: Twelve patients with papilla carcinoma were studied. The endosonographic findings were described in each case and depths were evaluated based on endosonographic images of the normal papilla and by comparison with endosonographic images of gastric carcinoma. The information was compared with the histopathological findings of the resected specimens. Results: Imaging criteria were proposed as follows: In d0 or T1, the papilla swelled preserving the basic structure; in d1 or T2, the papilla presented as a tumor but the non‐thickened duodenal fourth (proper muscle) layer was traceable behind the tumor; in d2 or T2, the papilla presented as a tumor fused with the thickened duodenal fourth layer; in d3 or T3–4, the papilla presented as a tumor and the duodenal fourth layer was partially or entirely untraceable behind the tumor. Accuracy of endosonography was 75% by the Japanese classification and 83.3% by the TNM system. Conclusions: Proposed endosonographic criteria are suitable for clinical application for assessing the depth of duodenal invasion of papilla carcinoma.

A long-term surviving patient with cancer of papilla of Vater after local resection

We report successful local resection for cancer of papilla of Vater in an 86-year-old woman. She was referred to our hospital because of right hypochondralgia. Abdominal ultrasonography and computed tomography showed marked dilatation of the common bile duct (CBD). Endoscopic retrograde cholangiography disclosed a small shadow defect in the terminal of the dilated CBD. Biopsy of the papilla revealed well-to-moderately differentiated adenocarcinoma. Considering her extreme old age and keeping in mind her quality of life after the operation, and the finding that the tumor was localized within the papilla and highly differentiated, we performed local resection. In addition, the intrapancreatic portion of the CBD and part of the main pancreatic duct (MPD) were further resected to secure a negative margin, confirmed by frozen section. The MPD was reapproximated to the duodenal mucosa and a choledocho-duodenostomy was performed for CBD reconstruction. Histopathological examination showed the tumor was papillary adenocarcinoma, 10 × 15 mm in size; there was no invasion beyond the sphincter of Oddi, it had partly infiltrated the CBD, but had not invaded to the pancreas or duodenum. The patient's postoperative course was not eventful and she has had good quality of life for the past 6 years since the operation, without any evidence of recurrence. Although radical pancreaticoduodenectomy is now the standard procedure in patients with malignant tumor of the papilla of Vater, local resection is a reasonable alternative for high-risk patients with highly differentiated, apparently localized carcinomas.

Influence of socio-demographic, clinical and functional factors on the severity of dementia

Dementia is one of the most relevant illnesses due to its functional impact on the elderly. The aim of the present study was to determine the influence of socio-demographic, clinical, cognitive and functional factors on the severity of dementia in elderly individuals. One hundred six elderly individuals with a diagnosis of dementia as determined by the DSM-IV/APA participated in the study. Cognition was assessed by the mini-mental state examination (MMSE); functional performance of basic and instrumental activities of daily living (BADLs and IADLs) was assessed by the Katz index (KI), Lawton-Brody index (LBI) and Pfeffer index (PI). The severity of dementia was established through the clinical dementia rating (CDR). In order to determine the influence of factors on the degree of dementia, ordinal regression analysis was performed. Age, MMSE, KI, LBI and PI scores had statistically significant associations to the severity of dementia. However, only the age (odds ratio (OR) = 0.197; confidence interval (CI) = 0.060-0.643) and performance in IADLs (LBI: OR = 1.237, CI = 1.077-1.422; PI: OR = 0.641, CI = 0.548-0.750) were maintained in the final ordinal regression model, R² = 0.818. The results show that elderly individuals over 80 years of age and those with a more compromised performance in IADLs have a greater chance of exhibiting more severe degrees of dementia. These findings suggest that the ability to perform IADLs may be an important variable in differentiating degrees of the severity of dementia.     

Pylorus-preserving pancreatoduodenectomy is applicable to patients with carcinoma of the head of the pancreas: Studies of lymph node metastasis and quality of life

Metastases to the regional lymph nodes of the stomach were studied in patients in whom carcinoma of the head of the pancreas had been resected (51 standard pancreatoduodenectomy and 26 total pancreatectomy). Involvement of gastric lymph nodes was rare (1.3%–3.9%), except of the subpyloric lymph nodes (9.1%). Carcinoma in the five patients with positive gastric lymph nodes, with the exception of the subpyloric nodes, was clinically far advanced: four of the five had liver metastasis or peritoneal dissemination. This suggests that, in terms of preservation of the regional gastric lymph nodes, only subpyloric node involvement has any significance with respect to surgical treatment of carcinoma of the head of the pancreas. There was no significant difference in survival rates after curative resection between standard pancreatoduodenectomy (n=44) and pylorus-preserving pancreatoduodenectomy (n=17). In the patients who underwent the pylorus-preserving pancreatoduodenectomy for various kinds of periampullary diseases (n=47), postoperative recovery of gastric and small bowel function was temporarily prolonged compared to that after shandard pancreatoduodenectomy (n=44). However, the former group were able to take significantly more calories 6 weeks after the operation. Our study indicates that the pylorus-preserving pancreatoduodenectomy with subpyloric lymph node dissection is applicable to the treatment of patients with carcinoma of the head of the pancreas from the viewpoints of both extent of operation and quality of life.     

TIMP-1和TIMP-2在原发性肝癌生长、浸润及转移中的作用

目的：了解基质金属蛋白酶组织抑制因子-1(tissue inhibitou of metalloproteinase-1，TIMP-1)和基质金属蛋白酶组织抑制因子-2(TIMP-2)mRNA及相关抗原在肝癌组织中的定位和表达状态，探讨TIMP-1和TIMP-2在肝癌组织生长、浸润及转移中所起的作用。方法：以TIMP-1和TIMP-2探针及单克隆抗体（McAb）为试剂，采用原位杂交技术及免疫组织化学法检测原发性肝癌、肝高分化腺癌的肝组织中TIMP-1和TIMP-2mRNA及相关抗原的表达，并与10例正常肝组织做对照。结果：20例原发性肝癌患者的肝组织中TIMP-1和TIMP-1mRNA及相关抗原表达的阳性率为90%;9例肝高分化腺癌的腺癌组织中无TIMP-1和TIMP-2mRNA及相关抗原的表达；10例正常肝组织中TIMP-1和TIMP-2mRNA及相关抗原表达均为阴性；TIMP-1和TIMP-2mRNA及相关抗原阳性信号呈现为棕黄色颗粒状，分布在肝细胞浆内，未见细胞核着色；无论是原发性肝癌癌组织还是癌周组织中,TIMP-1的表达强于TIMP-2的表达，癌周组织中TIMP-1和TIMP-2mRNA和相关抗原的表达与肝组织病理改变相关，即肝硬化者表达强，慢性肝炎者表达弱，正常肝组织无表达。结论：原发性肝癌的癌组织中存在TIMP-1和TIMP-2mRNA及相关抗原的表达，其表达强度可能与原发性肝癌的分型有关，它可能通过抑制MMP的活性使ECM降解减少从而阻止癌细胞通过基底膜移出而抑制肝癌细胞向周围浸润及转移。
