This is the first prospective randomized controlled trial on the oncological benefits of neoadjuvant treatment in BRPC. Compared to upfront surgery, neoadjuvant chemoradiation provides oncological benefits in patients with BRPC.

In cases of extrahepatic bile duct cancer, resection should be considered and efforts should be made to obtain a tumor-free margin. An aggressive surgical approach will give some survival benefit to the patients with even advanced disease. Long-term follow up is needed before declaring "a cure," because late recurrence after 5 years is detected not infrequently. Adjuvant therapy, local and systemic, needs to be further developed.

Although incidental pancreatic cystic neoplasms are being diagnosed with increasing frequency, little is known about the accurate prevalence of pancreatic cysts in the general population. The aims of this study were to evaluate the crude prevalence rate of pancreatic cystic neoplasms in asymptomatic healthy adults, and calculate the age- and sex-adjusted nationwide prevalence rate.A total of 21,745 asymptomatic individuals who underwent abdominal computed tomography (CT) as a health screening ex

The diagnostic accuracies of HRUS and EUS for the differential diagnosis of GB polypoid lesions were comparable. In view of patient comfort and no requirement for sedation, we consider that HRUS is likely to become an important diagnostic modality for the differential diagnosis and staging of GB polypoid lesions and early GB cancer.

A nomogram predicting malignancy in patients with BD-IPMN was constructed using a logistic regression model. This nomogram may be useful in identifying patients at risk of malignancy and for selecting optimal treatment methods. The nomogram is freely available at http://statgen.snu.ac.kr/software/nomogramIPMN.

Pancreatic IPMNs recur in 10.7% of patients. Recurrence is correlated with the degree of dysplasia, and 5.4% of patients with benign or noninvasive IPMN have recurrences including distant metastasis. Thorough postoperative surveillance is needed not only for patients with invasive IPMN but also for those with benign or noninvasive IPMN, especially for patients with high-grade dysplasia.

Tumor-infiltrating lymphocytes (TILs), found in patients with advanced pancreatic ductal adenocarcinoma (PDAC), are shown to correlate with overall survival (OS) rate. Although majority of TILs consist of CD8⁺/CD4⁺ T cells, the presence of NK cells and their role in the pathogenesis of PDAC remains elusive. We performed comprehensive analyses of TIL, PBMC, and autologous tumor cells from 80 enrolled resectable PDAC patients to comprehend the NK cell defects within PDAC. Ext

To determine if there is any difference in pancreatic function after pylorus-preserving pancreatoduodenectomy(PPPD) according to the type of pancreatoenterostomy [pancreatojejunostomy (P-J) or pancreatogastrostomy (P-G)], we evaluated the long-term functional status of 34 patients who underwent PPPD and survived for more than 1 year without clinical evidence of recurrence. Altogether 20 patients underwent P-J and 14 P-G. To compare the two groups, we analyzed the (1) general nutritional status;

Serum CA19-9 is significantly higher in patients with malignant IPMN, especially in patients with invasive and main duct type IPMN. The diagnostic power of serum CA19-9 in predicting malignancy is comparable to that of MPD >5 mm and mural nodules.
