Pancreatic ductal adenocarcinoma with synchronous and metachronous hepatic metastasis predicted by contrast-enhanced ultrasound.

Background: Contrast-enhanced ultrasound (CEUS) has proven valuable in diagnosing benign and malignant pancreatic diseases, but its value in evaluating hepatic metastasis remains to be further explored. This study investigated the relationship between CEUS features of pancreatic ductal adenocarcinoma (PDAC) and concomitant or recurrent liver metastases after treatment.

Methods: This retrospective study included 133 participants with PDAC who were diagnosed with pancreatic lesions with CEUS at Peking Union Medical College Hospital from January 2017 to November 2020.

Evaluation of the diagnostic performance of the EFSUMB CEUS Pancreatic Applications guidelines (2017 version): a retrospective single-center analysis of 455 solid pancreatic masses.

Objectives: To explore the diagnostic performance of EFSUMB CEUS Pancreatic Applications guidelines (version 2017) before and after the addition of iso-enhancement and very fast/fast washout as supplementary diagnostic criteria for PDAC.

Methods: In this retrospective study, patients diagnosed with solid pancreatic lesions from January 2017 to December 2020 were evaluated. Pancreatic ductal adenocarcinoma (PDAC) is reported to show hypo-enhancement in all phases according to the EFSUMB guidelines.

[Exploration and Practice of the Whole-course Care Mode from Hospital to Home for an Advanced Malignant Tumor Patient].

Unresectable pancreatic ductal adenocarcinoma: Role of CT quantitative imaging biomarkers for predicting outcomes of patients treated with chemotherapy.

Objectives: The primary aim of this study was to determine if computed tomographic (CT) texture analysis measurements of the tumor are independently associated with progression-free survival (PFS) and overall survival (OS) in patients with unresectable pancreatic ductal adenocarcinoma (PDAC), including both unresectable locally advanced and metastatic PDAC, who were treated with chemotherapy.

Methods: After an institutional review board waiver was obtained, contrast material-enhanced CT studies in 41 patients with unresectable PDAC who underwent contrast-enhanced CT before chemotherapy between 2014 and 2017 were analyzed in terms of tumor texture, with quantification of mean gray-level intensity (Mean), entropy, mean of positive pixels (MPP), kurtosis, standard deviation (SD), and skewness for fine to coarse textures (spatial scaling factor (SSF) 0-6, respectively). The association between pretreatment and posttreatment texture parameters, as well as Δ value (difference between posttreatment and pretreatment texture parameters), and survival time was assessed by using Cox proportional hazards models and Kaplan-Meier analysis.

Effect of Endostar combined with chemotherapy in advanced well-differentiated pancreatic neuroendocrine tumors.

The aim of the present study was to assess the effect of Endostar and temozolomide or dacarbazine plus 5-fluorouracil (5-FU) in patients with advanced pancreatic neuroendocrine tumors (pNETs).Phase II study of 14 patients with locally advanced or metastatic well-differentiated pNETs treated between April 2013 and September 2016. Patients received temozolomide or dacarbazine plus 5-FU, and Endostar.

[Efficacy and Prognostic Factors of Cetuximab Therapy in Treating KRAS or All RAS Wild-type Metastatic Colorectal Cancer].

Objective To explore the efficacy and prognostic factors of cetuximab therapy for KRAS or all RAS wild-type(WT)metastatic colorectal cancer(mCRC).Methods We screened mCRC patients receiving at least two cycles of cetuximb and chemotherapy from those with KRAS WT(before November 2013)or all-RAS-WT(after November 2013)in the Department of Medical Oncology,Peking Union Medical College Hospital from November 2007 to December 2016. The relationship between the clinicopathological characteristics and the efficacy was retrospectively analyzed.

Single Nucleotide Polymorphisms of Paclitaxel-induced Peripheral Sensory Neuropathy in Chinese Han Population.

Objective To study the single nucleotide polymorphisms (SNPs)that predict a patient's risk of grade 2-3 paclitaxel-induced peripheral sensory neuropathy (PSN) in Chinese Han populations.Methods Totally 216 patients received paclitaxel in Peking Union Medical College Hospital from May 2014 to December 2016 were enrolled.DNA was isolated from peripheral blood.

Efficacy of Gemcitabine and S-1 for Patients with Advanced Pancreatic Cancer.

Objective To explore the efficacy and toxicities of gemcitabine combined with S-1 in treating locally advanced and metastatic pancreatic ductal adenocarcinoma and prognostic factors. Methods We retrospectively analyzed the clinical data of patients with locally advanced and metastatic pancreatic cancer receiving gemcitabine and S-1 as first-line therapy in the Department of Medical Oncology,Peking Union Medical College Hospital from January 2014 to January 2017.Gemcitabine was administered at a dose of 1000 mg/m over 30 min-utes on days 1 and 8,and oral S-1 at a dose of 40-60 mg twice daily from days 1 to 14,repeated every 3 weeks.

Efficiency of Sunitinib in Chinese Patients with Advanced Progressive Pancreatic Neuroendocrine Tumor.

Objective To explore the efficiency of sunitinib in Chinese pancreatic neuroendocrine tumors (pNET) patients. Methods Advanced pNET patients who had accepted sunitinib treatment in the oncology department of PUMC Hospital from January 2009 to June 2015 after disease progression were enrolled in this study. Data collection included clinicopathological characteristics,medical therapies and outcomes.

Endostar combined with chemotherapy for treatment of metastatic colorectal and gastric cancer: a pilot study.

Background: Antiangiogenesis is a promising field of cancer therapy. Endostar, a novel recombinant human endostatin, is one of the few approved drugs acting as angiogenesis inhibitors of cancer in China. However, there are few clinical studies about Endostar in gastrointestinal cancer.

[Efficacy of gemcitabine combined with erlotinib in patients with advanced pancreatic cancer].

Objective: To evaluate the efficacy,clinical benefits and toxicities of gemcitabine combined with erlotinib for advanced pancreatic cancer.

Method: Clinical data of 20 patients with advanced pancreatic cancer treated with gemcitabine 1000 mg/m2 on day 1 and day 8 (repeated every 21 days) plus erlotinib 100-150 mg/d at Peking Union Medical College Hospital was reviewed retrospectively.

Results: No patient achieved complete remission or partial remission, 11 patients (55%) had stable disease, and 9 patients (45%) experienced disease progression.
