Metastatic pancreatic ductal adenocarcinoma (PDAC) is characterized by poor prognosis and short survival. Today, the use of new polytherapeutic regimens increases clinical outcome of these patients opening new clinical scenario. A crucial issue related to the actual improvement achieved with these new regimens is represented by the occasional possibility to observe a radiological complete response of metastatic lesions in patients with synchronous primary tumor. What could be the best therapeutic management of these patients? Could surgery represent an indication? Herein, we reported a case of a patient with PDAC of the head with multiple liver metastases, who underwent first-line chemotherapy with mFOLFIRINOX. After 10 cycles, he achieved a complete radiological response of liver metastases and a partial response of pancreatic lesion. A duodenocephalopancreasectomy was performed. Due to liver a lung metastases after 8 months from surgery, a second-line therapy was started with a disease-free survival and overall survival of 8 months and 45 months, respectively. Improvement in the molecular characterization of PDAC could help in the selection of patients suitable for multimodal treatments. This trial is registered with NCT02892305 and NCT00855634.

Aim. To establish the association between pancreatic cancer precursor lesions and chronic opisthorchiasis. Materials and methods. A single center case-control study was conducted at a low-volume pancreatic surgery center in Khanty-Mansiysk. We retrospectively collected morphological data from 47 pancreatoduodenectomies performed for pancreatic ductal adenocarcinoma. The study group included 23 cases of pancreatic ductal adenocarcinoma with concomitant chronic Opisthorchis felineus invasion which were compared to 24 controls consisting of “pure” cancer. Qualitative analysis was performed using χ2 Pearson criterion. Exact Fisher test was used for small samples. Time to progression and overall survival rates were calculated using Kaplan-Meier survival analysis. Data were collected and analyzed in Statistica 7.0. Results. PanINs were seen in 41,7% pancreata resected for ductal adenocarcinoma of the head and in 95,7% cases of pancreatic cancer in background of chronic opisthorchiasis (р = 0,000; 95% CI 3,5-268). PanIN high grade were observed only in opisthorchiasis group. In mixed pathology invasive cancer component tended to be more dedifferentiated and advanced when compared to pure cancer group (p = 0,029). Median disease free survival was 9 mo. in both groups and overall survival was 13 mo. in non-opisthorchiasis group and 15,3 mo. in opisthorchiasis group (р = 0,437). Conclusion. Chronic opisthorchiasis is associated with pancreatic intraepithelial neoplasia. Pancreatic ductal adenocarcinoma in background of opisthorchiasis with preneoplastic lesions tend to be more advanced in stage and poorly differentiated. Disease free and overall survival have no statistically significant differences in patients with and without Opisthorchis felineus invasion.

Abstract Background Cancer stem cells (CSCs) are implicated in carcinogenesis, cancer progression, and recurrence. Several biomarkers have been described for pancreatic ductal adenocarcinoma (PDAC) CSCs; however, their function and mechanism remain unclear. Method In this study, secretome analysis was performed in pancreatic CSC-enriched spheres and control adherent cells for biomarker discovery. Glutaredoxin3 (GLRX3), a novel candidate upregulated in spheres, was evaluated for its function and clinical implication. Results PDAC CSC populations, cell lines, patient tissues, and blood samples demonstrated GLRX3 overexpression. In contrast, GLRX3 silencing decreased the in vitro proliferation, migration, clonogenicity, and sphere formation of cells. GLRX3 knockdown also reduced tumor formation and growth in vivo. GLRX3 was found to regulate Met/PI3K/AKT signaling and stemness-related molecules. ELISA results indicated GLRX3 overexpression in the serum of patients with PDAC compared to that in healthy controls. The sensitivity and specificity of GLRX3 for PDAC diagnosis were 80.0 and 100%, respectively. When GLRX3 and CA19–9 were combined, sensitivity was significantly increased to 98.3% compared to that with GLRX3 or CA19–9 alone. High GLRX3 expression was also associated with poor disease-free survival in patients receiving curative surgery. Conclusion Overall, these results indicate GLRX3 as a novel diagnostic marker and therapeutic target for PDAC targeting CSCs.

Abstract Background: Oncological survival after operation of resectable pancreatic ductal adenocarcinoma (R-PDAC) is variable depending on various factors. Preoperative risk stratification could guide decision-making in multidisciplinary treatment concepts. We develop and validate a prognostic score for disease-free survival (DFS) in R-PDAC to solve this issue.Methods: 421 R-PDAC patients between January 2012 and December 2015 were enrolled. Performance of the final model was evaluated with respect to discrimination, calibration and clinical usefulness. A prognostic score based on the final model was developed, and external validated in 290 patients.Results: On multivariable analysis, age, tumor size, carbohydrate antigen (CA)19-9, CA125, lymphocyte-monocyte ratio, and systemic-immune-inflammation index were independently associated with DFS. Final model had acceptable calibration, discrimination and internal validity. The prognostic score could delineate low- and high-risk groups with median DFS of 19.6 and 10.1 months (P<0.0001). Tumors in high-risk group exhibited more aggressive pathobiological behaviors. Additionally, at 1-year follow-up, the restricted mean survival time was longer with adjuvant chemotherapy than those without in low-risk patients. However, no significant difference was detected in high-risk patients.Discussion: The prognostic score could accurately predict DFS preoperatively in R-PDAC patients and provide reference for risk-adapted strategies formulation for R-PDAC management in the future.

Chemotherapy is often difficult to treat human epidermal growth factor receptor 2 (HER2)-positive metastatic recurrent breast cancer in the elderly, and no standard treatment has been established at this point. We experienced a case in which trastuzumab (Tmab) + anastrozole (ANA) was ineffective (progressive disease; PD) in elderly HER2-positive breast cancer with postoperative multiple liver metastases, but T-DM1 was significantly effective (complete response; CR), and treatment could be continued safely. An 82-year-old woman was referred to our department with a right breast mass. A close examination revealed right breast cancer cT1bN0M0 cStage I, and total mastectomy and sentinel lymph node biopsy were performed. The postoperative pathological result was pT1bN0M0 pStage I (luminal HER2 type). The patient was elderly and had no adjuvant treatment after the operation. Approximately 2 years after the operation, multiple liver metastases were observed, and treatment with ANA and Tmab was started. Four months later, MRI showed that the number of multiple liver metastases increased. The patient was diagnosed with PD, and the anti-HER2 drug was changed from trastuzumab to trastuzumab emtansine (T-DM1). The dose was reduced due to vomiting (grade 3). Two months later, MRI showed that the multiple liver metastases shrank and became obscure after 5 months. After that, T-DM1 was continued, and the disease did not worsen. In elderly people with difficulty in administering chemotherapy, T-DM1 may have a safe and sufficient therapeutic effect by adjusting the dose and managing side effects appropriately.

Abstract Background Estimates of the incidence and prognosis of developing liver metastases at the pancreatic ductal adenocarcinoma (PDAC) diagnosis are lacking.Methods In this study, we analyzed the association of liver metastases and the PDAC patients outcome. The risk factors associated with liver metastases in PDAC patients were analyzed using multivariable logistic regression analysis. The overall survival (OS) was estimated using Kaplan-Meier curves and log-rank test. Cox regression was performed to identify factors associated with OS.Results Patients with primary PDAC in the tail of the pancreas had a higher incidence of liver metastases (62.2%) than those with PDAC in the head (28.6%). Female gender, younger age, primary PDAC in the body or tail of the pancreas, and larger primary PDAC tumor size were positively associated with the occurrence of liver metastases. The median survival of patients with liver metastases was significantly shorter than that of patients without liver metastases. Older age, unmarried status, primary PDAC in the tail of the pancreas, and tumor size ≥4 cm were risk factors for OS in the liver metastases cohort.Conclusions Population-based estimates of the incidence and prognosis of PDAC with liver metastases may help decide whether diffusion-weighted magnetic resonance imaging should be performed in patients with primary PDAC in the tail or body of the pancreas. The location of primary PDAC should be considered during the diagnosis and treatment of primary PDAC.

Background. Pancreatic cancer is a malignant tumor of the digestive tract, which is difficult to diagnose and treat due to bad early diagnosis. We aimed to explore the role of kinesin superfamily 4A (KIF4A) in pancreatic ductal adenocarcinoma (PDAC). Methods. We first used the bioinformatic website to screen the data of pancreatic cancer in TCGA, and KIF4A protein was detected among the 86 specimens of patients in our hospital combined with clinic-pathological characteristics and survival analysis. KIF4A loss-expression cell lines were established by RNA interference (RNAi). In addition, we performed in vitro cell assays to detect the changes in cell proliferation, migration, and invasion. The proteins involved in the proliferation and metastasis of cancer cells were also detected by western blot. The above results could be proved in vivo. Further, the correlation between KIF4A and CDC5L was analyzed by TCGA and IHC data. Results. We first found a high expression of KIF4A in pancreatic cancer, suggesting a role of KIF4A in the development of pancreatic cancer. KIF4A was found to be differentially expressed ( P < 0.05 ) among the 86 specimens of patients in our hospital and was significantly associated with PDAC TNM stages and tumor size. High KIF4A expression also significantly worsened overall survival (OS) and disease-free survival rate (DFS) ( P < 0.05 , respectively). In addition, cell proliferation, migration, and invasion were inhibited by the KIF4A-shRNA group compared with the control ( P < 0.05 , respectively). In the end, knockdown of KIF4A could inhibit tumor development and metastasis in vivo. Further, the positive correlation between KIF4A and CDC5L existed, and KIF4A might promote pancreatic cancer proliferation by affecting CDC5L expression. Conclusion. In conclusion, the high expression level of KIF4A in PDAC was closely related to poor clinical and pathological status, lymphatic metastasis, and vascular invasion. KIF4A might be involved in promoting the development of PDAC in vitro and in vivo, which might be a new therapeutic target of PDAC.
