  • Diagnosis and treatment of 45 patients with pancreas intraductal papillary mucinous neoplasm

    ObjectiveTo summarize clinical features, imaging findings, and pathological characteristics of pancreas intraductal papillary mucinous neoplasm (IPMN) and to improve effect of clinical diagnosis and treatment of pancreas IPMN.MethodThe clinical data of 45 patients with pancreas IPMN who underwent surgical resection from February 2014 to February 2019 in the First Affiliated Hospital of Soochow University were retrospectively analyzed.ResultsOf the 45 patients with pancreas IPMN, 28 patients were male and 17 patients were female, aged from 44 to 81 years old with (65±21) years old. There were 35 patients with age > 60 years old. The most common clinical manifestation was the upper abdominal discomfort (26 patients) and the lesions mainly occurred in the head of pancreas (20 patients). Twenty-four (58.5%, 24/41) patients and 17 (81.0%, 17/21) patients were definitely diagnosed by the CT and MRI, respectively. Twenty-five patients underwent the pancreaticoduodenectomy, 5 patients underwent the partial pancreatectomy, 2 patient underwent the pancreatic tumor resection, 12 patients underwent the pancreatic body and tail resection, 1 patient underwent the total pancreatectomy. The pathological findings showed that 15 cases were mild dysplasia, 5 cases were moderate dysplasia, 3 cases were severe dysplasia. Six cases invaded the pancreas and its surrounding adipose tissue, 5 cases invaded the tissue outside the pancreas. After the discharge, 28/32 patients were followed up for 3 to 24 months. Among all the followed-up patients, the 1-year survival rate was 100% (28/28) and the 2-year survival rate was 96.4% (27/28). The patients underwent the CT examination on the 3rd, 6th, 12th,18th, and 24th month, no lymph node metastasis was found.ConclusionsPancreas IPMN is more common in the elderly, mainly manifests as gastrointestinal symptoms, such as upper abdominal discomfort, etc. Surgery is its main treatment mean. Preoperative diagnosis mainly depends on CT examination and MRI examination, but positive rate of MRI examination is higher. Postoperative pathological section shows different degree of dysplasia.

  • Expression and clinical significance of B7S1 in gastric cancer

    ObjectiveTo analyze the difference of expression of B7 superfamily member 1 (B7S1) in gastric cancer and adjacent cancer tissues, and to explore the relationship between B7S1 expression and the clinicopathological characteristics and the prognosis of gastric cancer patients.MethodsReverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry were performed to investigate the expression of B7S1 in 78 cases of gastric cancer tissues and adjacent tissues. The correlation of B7S1 expressions with the clinicopathological characteristics and prognosis of the patients was analyzed.ResultsThe results showed that cancer tissues relative expression of B7S1 mRNA was higher than that of adjacent tissues, and the difference was statistically significant (P<0.05). The results showed that positive rate of B7S1 protein expression in gastric cancer tissues was significantly higher than that of adjacent tissues, 74.36% and 11.54%, the difference was statistically significant (P=0.001). Chi-square analysis showed that the expression of B7S1 protein was associated with tumor diameter (P=0.006), pathological-stage (P=0.002), T-stage (P=0.011), and lymph node metastasis (P=0.001). There were no relationship with gender, age, tumor site, and M-stage (P>0.05). B7S1 protein expression was correlated with the overall survival rate for gastric cancer patients. Both univariate and Cox multivariate survival analysis suggested that B7S1 positive expression was a risk factor for poor prognosis in patients with gastric cancer.ConclusionsThe relative expression level of B7S1 mRNA and the positive rate of protein expression in gastric cancer tissues are higher than those in adjacent tissues. The positive expression of B7S1 is correlated with the poor clinicopathological characteristics and prognosis. We speculate that B7S1 may be involved in the malignant progression of gastric cancer.
