Multidimensional characteristics, prognostic role, and preoperative prediction of peritoneal sarcomatosis in retroperitoneal sarcoma.

Background: Peritoneal sarcomatosis (PS) could occur in patients with retroperitoneal sarcomas (RPS). This study aimed to expand the understanding of PS on its characteristics and prognostic role, and develop a nomogram to predict its occurrence preoperatively.

Methods: Data of 211 consecutive patients with RPS who underwent surgical treatment between 2011 and 2019 was retrospectively reviewed.

Establishment of a multi-parameters MRI model for predicting small lymph nodes metastases (<10 mm) in patients with resected pancreatic ductal adenocarcinoma.

Purpose: To evaluate the potential role of MR findings and DWI parameters in predicting small regional lymph nodes metastases (with short-axis diameter < 10 mm) in pancreatic ductal adenocarcinomas (PDACs).

Methods: A total of 127 patients, 82 in training group and 45 in testing group, with histopathologically diagnosed PDACs who underwent pancreatectomy were retrospectively analyzed. PDACs were divided into two groups of positive and negative lymph node metastases (LNM) based on the pathological results.

[Study on determination and quantity transfer of multi index components in Wenjing Decoction].

Based on the textual research on literature, the key information of Wenjing Decoction were tested and identified, and 15 batches of lyophilized powder samples of Wenjing Decoction were prepared. The specific components, including paeoniflorin, glycyrrhizin, ginsenosides(Rg_1, Re and Rb_1), glycyrrhizic acid, and paeonol, were used as indexes to establish the HPLC method for quantitative evaluation, and the content ranges and transfer rates of these components were determined. The results showed that the contents of paeoniflorin, glycyrrhizin, ginsenosides Rg_1 + Re, ginsenoside Rb_1, glycyrrhizic acid, and paeonol in the 15 batches of samples were 0.

Prediction of Histologic Subtype and FNCLCC Grade by SUVmax Measured on F-FDG PET/CT in Patients with Retroperitoneal Liposarcoma.

This study aimed to evaluate the usefulness of maximum standardized uptake value (SUVmax) on F-fluorodeoxyglucose positron emission tomography with computed tomography (F-FDG PET/CT) in differentiating the subtypes and tumor grades of retroperitoneal liposarcoma (RPLS). The data of RPLS patients who underwent surgical resection from November 2013 to December 2019 at the sarcoma center of our institute were reviewed. The demographics, clinical features, and SUVmax of 84 patients who underwent preoperative F-FDG PET/CT scans were analyzed.

[Study on quality standard of fried Vaccariae Semen standard decoction].

According to the preparation principle of standard decoction of Chinese herbal medicines, fourteen batches of fried Vaccariae Semen decoction were prepared in this study and the quality research was carried out to establish a quality evaluation method for the standard decoction of fried Vaccariae Semen. The contents of vaccarin were determined, and its transfer rate from decoction piece to standard decoction was calculated. The extract rate and pH value were measured, and HPLC fingerprint method was established for analysis.

Pancreaticoduodenectomy for Retroperitoneal Sarcomas: A Mono-Institutional Experience in China.

Background: En bloc resection of retroperitoneal sarcoma (RPS) with adjacent organs such as pancreatic head and duodenum is challenging for surgeons. This mono-institutional study aims to evaluate the feasibility, safety, and outcome of performing pancreaticoduodenectomy (PD) during RPS resection.

Methods: The clinical data of RPS patients who underwent PD at the Sarcoma Center of Peking University Cancer Hospital from January 2011 to December 2019 was collected and analyzed.

Contralateral internal iliac artery transposition for retroperitoneal sarcoma involving common iliac artery.

Complete resection for retroperitoneal sarcoma (RPS) involving major vessels frequently requires vascular resection and reconstruction. The use of artificial grafts often leads to postoperative vascular graft infection (VGI), which usually requires reoperation and sometimes leads to death. In the present study, the data of RPS patients who underwent contralateral iliac artery (IIA) transposition for reconstruction of the common iliac artery (CIA) after RPS resection from 2015-2019 were retrospectively analyzed.

Clinicopathological features and prognostic factors of solid pseudopapillary neoplasms of pancreas.

.To explore the clinicopathological features of solid pseudopapillary neoplasm (SPN) of pancreas and to analyze the related factors of SPNs with aggressive behavior. Clinical data of SPN patients admitted in the Single Center of Peking University Cancer Hospital from January 2007 to September 2017 were retrospectively analyzed.

Ischemic Liver Injury After Complete Occlusion of Hepatic Artery in the Treatment of Delayed Postoperative Arterial Bleeding.

Background: Delayed postoperative arterial bleeding is rare and may be life-threatening. When the bleeding source is the hepatic artery, complete ligation or embolization from the proximal to the distal area of the ruptured lesion usually results in complete occlusion of hepatic arterial flow.

Methods: To evaluate the frequency and severity of ischemic liver injury following complete hepatic artery occlusion, a retrospective study was conducted.

En bloc pancreaticoduodenectomy and right colectomy in the treatment of locally advanced colon cancer.
