Clinical and molecular characteristics of patients with brain metastasis secondary to pancreatic ductal adenocarcinoma. Oncologist 2024:oyae182. [PMID: 39014543 DOI: 10.1093/oncolo/oyae182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Accepted: 06/21/2024] [Indexed: 07/18/2024] Open
Abstract
BACKGROUND The prognosis for patients with pancreatic ductal adenocarcinoma (PDAC) is poor. Secondary brain metastasis (Br-M) occurs in less than 1% of patients. Clinical characteristics and molecular alterations have not been characterized in this rare patients' subset. MATERIALS AND METHODS The Foundry software platform was used to retrospectively query electronic health records for patients with Br-M secondary to PDAC from 2005 to 2023; clinical, molecular, and overall survival (OS) data were analyzed. RESULTS Br-M was diagnosed in 44 patients with PDAC. Median follow-up was 78 months; median OS from initial PDAC diagnosis was 47 months. Median duration from PDAC diagnosis to Br-M detection was 24 months; median OS from Br-M diagnosis was 3 months. At Br-M diagnosis, 82% (n = 36) of patients had elevated CA19-9. Lung was the most common preexisting metastatic location (71%) with Br-M, followed by liver (66%). Br-M were most frequently observed in the frontal lobe (34%, n = 15), cerebellar region (23%, n = 10), and leptomeninges (18%, n = 8). KRAS mutations were detected in 94.1% (n = 16) of patients who had molecular data available (n = 17) with KRASG12V being the most frequent subtype 47% (n = 8); KRASG12D in 29% (n = 5); KRASG12R in 18% (n = 3). Patients who underwent Br-M surgical resection (n = 5) had median OS of 8.6 months, while median OS following stereotactic radiosurgery only (n = 11) or whole-brain radiation only (n = 20) was 3.3 and 2.8 months, respectively. CONCLUSION Br-M is a late PDAC complication, resulting in an extremely poor prognosis especially in leptomeningeal disease. KRAS was mutated in 94.1% of the patients and the KRASG12V subtype was prevalent.

Wei Z, Srinivasan P, Patel R, Bednarz G, Flickinger JC, Hadjipanayis CG, Niranjan A, Lunsford LD. Stereotactic Radiosurgery for Patients with Brain Metastases from Hepatopancreaticobiliary Cancers. Cancers (Basel) 2024; 16:1665. [PMID: 38730617 PMCID: PMC11083154 DOI: 10.3390/cancers16091665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 04/21/2024] [Accepted: 04/22/2024] [Indexed: 05/13/2024] Open
Abstract
BACKGROUND The role of stereotactic radiosurgery (SRS) for patients with brain metastases from hepatopancreaticobiliary (HPB) cancers has yet to be established. The authors present a single-institution experience of patients with HPB cancers who underwent SRS when their cancer spread to the brain. METHODS We surveyed our Gamma Knife SRS data base of 18,000 patients for the years 1987-2022. In total, 19 metastatic HPB cancer patients (13 male) with 76 brain metastases were identified. The median age at SRS was 61 years (range: 48-83). The primary cancer sites were hepatocellular carcinoma (HCC, 11 patients), cholangiocarcinoma (CCC, 2 patients), and pancreatic carcinoma (PCC, 6 patients). The median Karnofsky Performance Score (KPS) was 80 (range: 50-90). Two patients underwent pre-SRS whole-brain fractionated radiation therapy (WBRT) and eight patients underwent pre-SRS surgical resection. All SRS was delivered in single session. The median margin dose was 18 Gy (range: 15-20). The median cumulative tumor volume was 8.1 cc (range: 1.0-44.2). RESULTS The median patient overall survival (OS) after SRS was 7 months (range 1-79 months). Four patients had documented local tumor progression after SRS at a median time of 8.5 months (range: 2-15) between SRS and progression. Out of 76 treated tumors, 72 tumors exhibited local control. The local tumor control rate per patient was 78.9%. The local tumor control per tumor was 94.7%. Four patients developed new brain metastases at a median of 6.5 months (range: 2-17) after SRS. No patient experienced adverse radiation effects (AREs). At the last follow-up, 18 patients had died, all from systemic disease progression. CONCLUSIONS Metastatic spread to the brain from HPB cancers occurs late in the course of the primary disease. In this study, all deceased patients ultimately died from primary disease progression. SRS is a non-invasive strategy that maximally preserves quality of life, and our results reported favorable outcomes compared to the existing literature. SRS should be considered as one of the primary management strategies for patients with brain metastatic spread from HPB cancer.

Abstract
OBJECTIVE The natural history, treatment options, and clinical outcomes of pancreatic metastases to the brain remain largely unknown. Here, we seek to investigate characteristics that influence OS in pancreatic metastases to the brain. METHODS This is a population-based retrospective study of OS in 508 patients with pancreatic metastases to the brain using the SEER database. Univariate and multivariate Cox regression analyses were utilized, and a predictive nomogram was developed. RESULTS There were 508 patients identified for this study, with a median OS of 2 months. In the univariate analysis, patients older than 65 years had significantly reduced OS (P < 0.001). Patients with liver metastases (P < 0.001) and liver and lung metastases (P < 0.001) exhibited significantly reduced OS. Treatment of the primary tumor with chemotherapy only (P < 0.001), radiation only (P = 0.01), radiation and chemotherapy (P < 0.001), and surgery only (P = 0.01) were associated with increased OS. Resection of a distant metastasis site (P = 0.009) and of a brain metastasis (P = 0.03) were associated with increased OS. In the multivariable analysis, factors that remained significant included patient age (P = 0.01), liver metastases (P < 0.001), liver and lung metastases (P < 0.001), treatment with chemotherapy (P < 0.001), treatment with radiation and chemotherapy (P < 0.001), and treatment with surgery and chemotherapy (P < 0.001). The nomogram had a C-index of 0.766, suggesting congruence between the findings on the nomogram and the results in the internal verification. CONCLUSIONS Median OS is influenced by age, multiorgan metastases, and treatment of the primary tumor. These data highlight the marginal benefit of treatment, yet improved quality of life (QOL) remains to be elucidated.

Abstract
Pancreatic cancer (PC) is a fatal malignancy in the human abdominal cavity that prefers to invade the surrounding nerve/nerve plexus and even the spine, causing devastating and unbearable pain. The limitation of available in vitro models restricts revealing the molecular mechanism of pain and screening pain-relieving strategies to improve the quality of life of end-stage PC patients. Here, we report a PC nerve invasion model that merged human brain organoids (hBrO) with mouse PC organoids (mPCO). After merging hBrOs with mPCOs, we monitored the structural crosstalk, growth patterns, and mutual interaction dynamics of hBrO with mPCOs for 7 days. After 7 days, we also analyzed the pathophysiological statuses, including proliferation, apoptosis and inflammation. The results showed that mPCOs tend to approximate and intrude into the hBrOs, merge entirely into the hBrOs, and induce the retraction/shrinking of neuronal projections that protrude from the margin of the hBrOs. The approximating of mPCOs to hBrOs accelerated the proliferation of neuronal progenitor cells, intensified the apoptosis of neurons in the hBrOs, and increased the expression of inflammatory molecules in hBrOs, including NLRP3, IL-8, and IL-1β. Our system pathophysiologically replicated the nerve invasions in mouse GEMM (genetically engineered mouse model) primary and human PCs and might have the potential to be applied to reveal the molecular mechanism of nerve invasion and screen therapeutic strategies in PCs.

Abstract
PURPOSE OF REVIEW Lung cancer is one of the most common malignant tumours worldwide. Metastasis is a serious influencing factor for poor treatment effect and shortened survival in lung cancer. But the complicated underlying molecular mechanisms of tumour metastasis remain unclear. In this review, we aim to further summarize and explore the underlying mechanisms of tumour-derived exosomes (TDEs) in lung cancer metastasis. RECENT FINDINGS TDEs are actively produced and released by tumour cells and carry messages from tumour cells to normal or abnormal cells residing at close or distant sites. Many studies have shown that TDEs promote lung cancer metastasis and development through multiple mechanisms, including epithelial-mesenchymal transition, immunosuppression and the formation of a premetastatic niche. TDEs regulate these mechanisms to promote metastasis by carrying DNA, proteins, miRNA, mRNA, lncRNA and ceRNA. Further exploring TDEs related to metastasis may be a promising treatment strategy and deserve further investigation. SUMMARY Overall, TDEs play a critical role in metastatic of lung cancer. Further studies are needed to explore the underlying mechanisms of TDEs in lung cancer metastasis.

Abstract
Brain metastasis (BM) is a common complication in cancer patients with advanced disease and attributes to treatment failure and final mortality. Currently there are several therapeutic options available; however these are only suitable for limited subpopulation: surgical resection or radiosurgery for cases with a limited number of lesions, targeted therapies for approximately 18% of patients, and immune checkpoint inhibitors with a response rate of 20-30%. Thus, there is a pressing need for development of novel diagnostic and therapeutic options. This overview article aims to provide research advances in disease model, targeted therapy, blood brain barrier (BBB) opening strategies, imaging and its incorporation with artificial intelligence, external radiotherapy, and internal targeted radionuclide theragnostics. Finally, a distinct type of BM, leptomeningeal metastasis is also covered.

Abstract
Background Pancreatic cancer is one of the leading causes of cancer mortality and one of the most lethal malignant neoplasms worldwide. It is known for its local tumor extension to the liver; other common sites include the lung, distant lymph nodes, and bone. Brain metastases are extremely rare and represent less than 0.6% of all brain metastases. Case report We report the case of a 66-year-old Caucasian female known to have adenocarcinoma of the tail of the pancreas treated with chemotherapy. During follow-up, thoracoabdominal computed tomography scans did not reveal any residual tumor or any metastasis. Moreover, tumor markers were within normal limits. She presented to the emergency department of our institution following an episode of a generalized tonic–clonic seizure 5 years following the initial diagnosis. Brain magnetic resonance imaging revealed an expansive left frontal intraaxial lesion compatible with high-grade glioma. The patient underwent surgical treatment. Histological examination revealed pancreatic metastasis. Conclusions Thought to be rare, metachronous cerebral pancreatic metastasis should be kept in mind in patients with pancreatic cancer. Early diagnosis and complete surgical resection play a key role in the survival of these patients.

Abstract
Tumor-derived exosomes (TDEs) are actively produced and released by tumor cells and carry messages from tumor cells to healthy cells or abnormal cells, and they participate in tumor metastasis. In this review, we explore the underlying mechanism of action of TDEs in tumor metastasis. TDEs transport tumor-derived proteins and non-coding RNA to tumor cells and promote migration. Transport to normal cells, such as vascular endothelial cells and immune cells, promotes angiogenesis, inhibits immune cell activation, and improves chances of tumor implantation. Thus, TDEs contribute to tumor metastasis. We summarize the function of TDEs and their components in tumor metastasis and illuminate shortcomings for advancing research on TDEs in tumor metastasis.

Abstract
Background The global incidence and mortality rates of liver cancer, which is the second leading cause of cancer-related deaths worldwide, are increasing. However, information on its epidemiology and clinical prognosis is limited. This study aimed to characterize the epidemiology and prognostic factors of secondary liver cancer to aid in the pretreatment evaluation of the disease. Methods Patients diagnosed with secondary liver cancer between 2010 and 2014 in the Surveillance, Epidemiology, and End Results (SEER) database were retrospectively included. Kaplan-Meier analysis and Multivariate Cox regression analysis were performed to screen for significant factors associated with secondary liver cancer. Results A total of 85,738 secondary liver cancer patients were identified; in this population, the first primary site was the lung (25.9%), followed by the colorectum, pancreas, stomach, breast, and cecum. Patients with primary tumors of the colorectum, cecum and breast had longer median survival time. Advanced age, male gender, black race, poor differentiation or lack of differentiation, regional lymph node metastases, and presence of distant metastasis were associated with poor prognosis. Conclusions In this study, novel findings on the role of the primary site and synchronous distant metastasis to specific organs in patients with secondary liver cancer were described. These findings have significant implications in clinical diagnosis and treatment, and provide a better understanding of secondary liver cancer in the general population.

Liu M, Wang M, Li S. Prognostic Factors of Survival in Pancreatic Cancer Metastasis to Liver at Different Ages of Diagnosis: A SEER Population-Based Cohort Study. Front Big Data 2021; 4:654972. [PMID: 34651122 PMCID: PMC8507850 DOI: 10.3389/fdata.2021.654972] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 08/16/2021] [Indexed: 12/24/2022] Open
Abstract
Background: Liver is a common metastatic organ for most malignancies, especially the pancreas. However, evidence for prognostic factors of pancreatic cancer metastasis to the liver at different ages is lacking. Thus, we aimed to evaluate the predictors of patients with pancreatic cancer metastasis to liver grouped by age of diagnosis. Methods: We chose the patients diagnosed between 2004 and 2015 from the SEER database. The primary lesions of metastatic liver cancer between sexes were compared using the Pearson’s chi-square test for categorical variables. The overall survival (OS) and cancer-specific survival (CSS) were the endpoint of the study. The prognostic factors were analyzed with the Kaplan-Meier method and log-rank test, and Cox proportional-hazards regression model. Results: The main primary sites of metastatic liver cancer for our patients are lung and brunchu, sigmoid colon, pancreas, which in males are lung and bronchu, sigmoid colon and pancreas, while breast, lung and bronchu, sigmoid colon in females. Furthermore, we explored the prognostic factors of pancreatic cancer metastasis to liver grouped by age at diagnosis. Tumor grade, histology and treatment are valid prognostic factors in all age groups. Additionally, gender and AJCC N stage in age<52 years old, while race and AJCC N stage in age >69 years old were predictors. Surgery alone was the optimal treatment in group age>69 years old, whereas surgery combined with chemotherapy was the best option in the other groups. Conclusion: Our study evaluated the predictors of patients with pancreatic cancer metastasis to liver at various ages of diagnosis.

Combined modality therapy including cytoreductive surgery and heated intraperitoneal chemotherapy for synchronous low volume peritoneal carcinomatosis from adenocarcinoma of the tail of pancreas in a BRCA-2 carrier resulting in long-term disease-free survival: A case report. Int J Surg Case Rep 2021; 83:106047. [PMID: 34091215 PMCID: PMC8188393 DOI: 10.1016/j.ijscr.2021.106047] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 05/26/2021] [Accepted: 05/26/2021] [Indexed: 01/08/2023] Open
Abstract
INTRODUCTION A BRCA-2 mutation carrier with a metachronous pancreatic adenocarcinoma (PC) and established peritoneal metastases is presented. Combined modality therapy including Cytoreductive Surgery (CS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) was associated with long-term disease-free survival. CASE PRESENTATION A 62-yr. old female underwent successful treatment for stage IIIa carcinoma of the right breast at age 48. 11 years later a cystic adenocarcinoma of the tail of the pancreas with peritoneal metastases was diagnosed. Platin based neoadjuvant chemotherapy followed by definitive resection of the pancreatic mass with cytoreductive surgery (CS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) with mitomycin C was performed. Postoperatively, a retro-gastric fluid collection developed from a pancreatic duct leak, successfully managed non-operatively. Maintenance poly ADP ribose polymerase (PARP) inhibitor therapy was initiated after recovery from surgery. The patient experienced a 30-month disease free survival and was subsequently found to have oligometastases to the brain. DISCUSSION CR and HIPEC have not been reported to be efficacious in patients with pancreatic carcinomatosis. However, PC arising in BRCA-2 carriers has a DNA repair defect, which is sensitive to platin based chemotherapy and mitomycin C. HIPEC has more severe postoperative complications following distal pancreatectomy. Isolated brain metastases from PC are rare. BRCA-2 mutation carriers are at significantly increased risk for PC. CONCLUSION Leveraging the DNA Repair defect in BRCA-2 pancreatic adenocarcinoma, including CS and HIPEC, led to long-term disease-free survival and good locoregional control in this patient. Complications from HIPEC are more severe. BRCA-2 carriers should undergo annual pancreatic cancer screening.

Abstract
Numerous studies demonstrated that microRNAs (miRNAs) were highly involved in pancreatic cancer development. However, the functional roles of many miRNAs remain elusive in pancreatic cancer. In the present study, we analyzed previous published microarray data and found that miR-1469-5p was one of top upregulated miRNAs in pancreatic tumors. Our further study showed that miR-1469-5p was highly expressed in collected pancreatic tumors and its upregulation was associated with lymph node metastasis and tumors of advanced TNM stage. Functional analysis with miR-1469-5p inhibitor showed that downregulation of miR-1469-5p repressed pancreatic cancer cell proliferation and invasion. Mechanistically, miR-1469-5p directly interacted with metastasis suppressor NDRG1 mRNA and downregulated expression of NDRG1 to activate NF-κB pathway in pancreatic cancer cells. It was also found that miR-1469-5p decreased expression of E-cadherin, a metastasis related gene repressed by NF-κB pathway, in pancreatic cancer cells. Transfection of NDRG1 small interference RNA (siRNA) attenuated the function of miR-1469-5p inhibitor in pancreatic cancer cells. Moreover, miR-1469-5p expression was negatively associated with NDRG1 and E-cadherin mRNA levels in pancreatic tumors. Taken together, miR-1469-5p may exert its oncogenic potential in pancreatic cancer via regulating a NDRG1/NF-κB/E-cadherin axis, suggesting that it may be clinically valuable as a prognostic biomarker of pancreatic cancer.

Abstract
Background: Pancreatic cancer is a fatal disease most often diagnosed at an advanced stage. Most patients already suffer from irresectable tumor or distant metastases being most commonly found in the liver or the lung. However, cerebral metastases occur extremely rare.Methods: We performed a retrospective analysis of our database to identify all patients diagnosed with pancreatic cancer and cerebral metastases who underwent surgical treatment in our department from January 2004 to November 2016.Results: Only 0.2% (4 of 2492) were diagnosed with cerebral metastases. Two patients had surgical resection of the cerebral metastases. One patient underwent palliative radiation therapy and the fourth patient received only palliative therapy. Mean interval between initial diagnosis and development of brain metastases was 8.5 months (range 1-20). Mean survival period after diagnosis of brain metastases was 4.75 months (range 1-10).Conclusions: Cerebral metastases of pancreatic cancer occur extremely rare. They are associated with an advanced tumor stage, commonly liver and lung metastases. All patients presenting with neurological symptoms, multifocal metastases, and significantly elevated CA 19-9 levels are suspicious of sustaining cerebral metastases and should undergo brain imaging.

Abstract
BACKGROUND Significant modifications have been made to the 8th edition of the American Joint Committee on Cancer (AJCC) distant metastases (M) stage classification for metastatic pancreatic neuroendocrine tumors (PanNETs). We aimed to validate this revised classification among metastatic PanNET patients using the Surveillance, Epidemiology, and End Results database. We further sought to evaluate the feasibility of applying this classification to metastatic pancreatic neuroendocrine carcinoma (PanNEC) and pancreatic ductal adenocarcinoma (PDAC) patients. METHODS Stage IV pancreatic neuroendocrine neoplasm (PanNEN, including G1/G2 PanNET and G3 PanNEC classified according to the World Health Organization [WHO] 2010 grading scheme) and PDAC patients with metastatic disease diagnosed between 2010 and 2015 were identified and restaged according to the revised M stage classification for PanNET. Overall survival (OS) was compared using Kaplan-Meier analysis and log-rank test. Uni- and multivariate Cox regression models were utilized to identify prognostic factors. RESULTS A total of 1,371 stage IV PanNEN and 634 PDAC patients were included. Among PanNEN patients, liver (75.0%) was the most common metastatic site, followed by distant lymph nodes (8.5%), lung (8.4%), bone (7.3%), and brain (1.0%). The 5-year OS for PanNET patients with M1a, M1b, and M1c stage was 44.15, 53.32, and 19.70%, respectively. However, survival comparison showed no significant difference between M1a and M1b stages among PanNET patients. Similar findings were noted after applying this classification to PanNEC patients. Multivariate analysis showed that the age at diagnosis and the number of distant metastatic sites were independent prognostic factors for metastatic PanNEN patients. Interestingly, excellent survival discrimination by M stage among stage IV PDAC patients was noted (M1a vs. M1b vs. M1c, 5-year OS: 5.42, 2.46, and 0%, respectively). CONCLUSION Our study is the first large sample-based validation of the AJCC 8th M stage classification for PanNET. The revised classification did not effectively stratify metastatic PanNEN patients. However, further study is warranted to validate this classification for PanNET patients according to the WHO 2017 classification. Interestingly, the revised M stage classification might be feasible for PDAC patients with metastatic disease.

Abstract
Pancreatic adenocarcinoma (PAAD), one of the most prevailing malignant tumors in digestive system, is identified as one of the main culprits of cancer-associated mortality. Despite long intergenic non-protein coding RNA 1232 (LINC01232) is found to be upregulated in TCGA PAAD tissues and associated with poor prognosis, the potential of LINC01232 in PAAD progression still needs more explorations. In this study, LINC01232 was chosen to be the research object in PAAD cellular processes. Functionally, loss-of function assays were carried out and the experimental results indicated that suppression of LINC01232 hindered the deterioration of PAAD by affecting cell proliferation and migration. Furthermore, relationship between LINC01232 and its nearby gene transmembrane 9 superfamily member 2 (TM9SF2) was investigated. The same expression pattern of TM9SF2 in TCGA PAAD samples was observed. It was found that upregulation of LINC01232 could be a crucial factor for the dysregulation of TM9SF2. Mechanistically, LINC01232 recruited EIF4A3 to boost TM9SF2 mRNA stability. Besides, our findings demonstrated that the transcriptional activation of LINC01232 and TM9SF2 was mediated by SP1. Therefore, we concluded that LINC01232 executed carcinogenic properties in PAAD progression via regulation of TM9SF2. In conclusion, this study was the first to unveil the role and molecular mechanism of LINC01232, suggesting LINC01232 as a promising molecular target for pancreatic cancer treatment.

Abstract
Background: Few studies have explored the relationship between clinicopathological factors of patients with pancreatic ductal adenocarcinoma (PDAC) and liver metastasis. The aim of this study was to develop and validate a nomogram to predict liver metastasis in patients with PDAC. Patients and methods: Patients diagnosed with PDAC between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database were retrospectively collected. The nomogram was established based on a logistic regression model. The precision of the nomogram was evaluated and compared using concordance index (C-index), and the area under receiver operating characteristic curve (AUC). The clinical use of nomogram was evaluated by making use of a decision curve analysis (DCA). Results: A total of 12,644 eligible patients, which were randomly divided into training (n=9,483) and validation cohorts (n=3,161), were included in this study. The nomograms, which were established on the basis of independent predictors, were well calibrated, and demonstrated good discriminative ability, with C-indexes of 0.784 for the training cohort and 0.790 for validation cohort. The values of AUC for training and validation cohort were 0.792 and 0.800, respectively. When other sites of distant metastases were included into this predictive system, the new predictive model demonstrated a better discriminative ability and greater net benefit in predicting liver metastasis in patients with PDAC in both the training and validation cohorts. Conclusion: Nomograms were constructed to predict liver metastasis in patients with PDAC. Validation revealed excellent discrimination and calibration of the nomograms, suggesting that the nomograms were well calibrated and could serve to improve the prediction of the risks of liver metastasis which can be used to guide the management of patients with PDAC.

Abstract
OBJECTIVE Pancreatic carcinoma (PC), one of the most prevalent and malignant tumors, has a poor prognosis and a high mortality rate. EG-VEGF, a vascular endothelial growth factor from endocrine glands, also termed as PROK1, has a high positive expression rate in PC tissues and is involved in the pathogenesis of various tumors. However, the expression and potential role of EG-VEGF in PC has not been thoroughly explored. The aim of this study was to better clarify the expression and potential role of EG-VEGF in pancreatic carcinoma. METHODS Immunohistochemical staining, western blotting, and RT-qPCR analysis were performed to detect the EG-VEGF level in PC tissues and cells. Subsequently, two short hairpin RNA (shRNA) lentiviral expression vector, shPROK1-1/shPROK1-2, were transfected into PANC-1 and BxPC-3 PC cell lines. MTT assay was used to determine cell proliferation. Meanwhile, flow cytometry assay was conducted to measure cell cycle and cell apoptosis. The protein levels of PI3K/AKT/mTOR pathway-related genes were also determined by western blotting. RESULTS EG-VEGF was aberrantly expressed in PC samples, as compared with paracancerous samples. Knockdown of PROK1 notably decreased the protein level of EG-VEGF, indicating a successful downregulation model of EG-VEGF. EG-VEGF silencing remarkably attenuated cell proliferation, while also induced G0/G1 arrest and magnified the extent of cell apoptosis. Further, EG-VEGF knockdown significantly inhibited PI3K/AKT/mTOR signaling pathway by downregulating p-PI3K, p-AKT, and p-mTOR levels. CONCLUSION This study identified the high-expression of EG-VEGF in pancreatic carcinoma tissues and cells, and demonstrated that EG-VEGF silencing inhibits the proliferation of PC cells and promotes apoptosis via regulating PI3K/AKT/mTOR pathway. Thus, EG-VEGF may become an essential target for the therapy of pancreatic cancer in the future.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-related death with a median survival of 3–11 months when metastatic. We present a patient with metastatic pancreatic cancer and an exceptional response to initial systemic chemotherapy with FOLFIRINOX (fluorouracil, leucovorin, irinotecan, and oxaliplatin). Despite evidence of disease control on body imaging, he developed symptomatic leptomeningeal disease and brain metastases 29 months into treatment. He received aggressive treatment with capecitabine and irinotecan, intrathecal topotecan, and eventually bevacizumab. He did well for 36 weeks on this regimen until developing sepsis. This patient significantly outlived his expected survival and, moreover, did so with very good quality of life. This case demonstrates the natural history of pancreatic cancer progressing to involve the central nervous system when systemic disease is otherwise responsive to chemotherapy. It is the first case to demonstrate the potential effectiveness of intrathecal topotecan in combination with systemic chemotherapy for the treatment of leptomeningeal metastases of pancreatic cancer.

Abstract
BACKGROUND The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for pancreatic exocrine adenocarcinoma has been released. The current study seeks to assess the 7th and 8th editions among patients registered within the surveillance, epidemiology and end results (SEER) database. METHODS SEER database (2010-2013) has been accessed through SEER*Stat program and AJCC 8th edition stages were reconstructed utilizing the collaborative stage descriptions. Kaplan-Meier analysis of overall survival and pancreatic cancer-specific survival analyses (according to both 7th and 8th editions and according to whether pathological or clinical staging were conducted) has been performed. Multivariate analysis of factors affecting pancreatic cancer-specific survival was also conducted through a Cox proportional hazard model. RESULTS A total of 18 948 patients with pancreatic adenocarcinoma were identified in the period from 2010-2013. Pancreatic cancer-specific survival among pathologically staged patients and according to the 8th edition showed significant differences for all pair wise comparisons among different stages (P < 0.0001) except for the comparison between stage IA and stage IB (P = 0.307) and the comparison between stage IB and stage IIA (P = 0.116). Moreover, P value for stage IA vs IIA was 0.014; while pancreatic cancer-specific survival according to the 7th edition among pathologically staged patients showed significant differences for all pair wise comparisons among different stages (P < 0.0001) except for the comparison between IA and IB (P = 0.072), the comparison between stage IIA and stage IIB (P = 0.065), the comparison between stage IIA and stage III (P = 0.059) and the comparison between IIB and III (P = 0.595). Among clinically staged patients (i.e. those who did not undergo initial radical surgery), the prognostic performance of both 7th and 8th stages for both overall survival and pancreatic cancer-specific survival was limited. CONCLUSION There is clearly a need to have two staging systems for pancreatic adenocarcinoma: pathological and clinical staging systems.

CCR5/CCL5 axis interaction promotes migratory and invasiveness of pancreatic cancer cells. Sci Rep 2018; 8:1323. [PMID: 29358632 PMCID: PMC5778036 DOI: 10.1038/s41598-018-19643-0] [Citation(s) in RCA: 106] [Impact Index Per Article: 17.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Accepted: 01/02/2018] [Indexed: 02/07/2023] Open
Abstract
Pancreatic cancer (PC) is one of the deadliest cancers and remains a major challenge due to its invasive and metastatic nature. Increased levels of CCR5 and CCL5 have established indicators for disease status in various cancers, including PC. However, their role in invasion and metastasis of PC is not known. Here we conducted immunohistochemistry of PC tissues and found elevated epithelial staining for CCR5 and CCL5 in metastatic PC tissues compared to non-neoplastic. In vitro experiments, such as flow cytometry, immunofluorescence and western blotting with human PC cell lines (AsPc-1, BxPc-3 and MIA PaCa-2), showed higher expression levels of CCR5. The CCL5 activation of PC cells expressing CCR5 increased their invasive potential, while treatment with CCR5 inhibitor maraviroc inhibited the CCL5 activation. CCL5 induced proliferation of PC cells was mediated through F-actin polymerization, while there was marked reduction when the cells were treated with maraviroc. The direct interaction of CCR5 with CCL5 was verified using a calcium mobilization assay. Taken together, our results demonstrate that CCR5 and CCL5 are potential markers for metastatic PC cancer, and their interaction leads to the increased PC cell invasion. Thus, blocking CCR5/CCL5 axis might prove beneficial to prevent metastasis and provide a more therapeutic strategy to control PC progression.

Prognostic value of site-specific metastases in pancreatic adenocarcinoma: A Surveillance Epidemiology and End Results database analysis. World J Gastroenterol 2017; 23:1872-1880. [PMID: 28348494 PMCID: PMC5352929 DOI: 10.3748/wjg.v23.i10.1872] [Citation(s) in RCA: 117] [Impact Index Per Article: 16.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2016] [Revised: 12/20/2016] [Accepted: 02/07/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate the prognostic value of site-specific metastases among patients with metastatic pancreatic carcinoma registered within the Surveillance, Epidemiology and End Results (SEER) database. METHODS SEER database (2010-2013) has been queried through SEER*Stat program to determine the presentation, treatment outcomes and prognostic outcomes of metastatic pancreatic adenocarcinoma according to the site of metastasis. In this study, metastatic pancreatic adenocarcinoma patients were classified according to the site of metastases (liver, lung, bone, brain and distant lymph nodes). We utilized chi-square test to compare the clinicopathological characteristics among different sites of metastases. We used Kaplan-Meier analysis and log-rank testing for survival comparisons. We employed Cox proportional model to perform multivariate analyses of the patient population; and accordingly hazard ratios with corresponding 95%CI were generated. Statistical significance was considered if a two-tailed P value < 0.05 was achieved. RESULTS A total of 13233 patients with stage IV pancreatic cancer and known sites of distant metastases were identified in the period from 2010-2013 and they were included into the current analysis. Patients with isolated distant nodal involvement or lung metastases have better overall and pancreatic cancer-specific survival compared to patients with isolated liver metastases (for overall survival: lung vs liver metastases: P < 0.0001; distant nodal vs liver metastases: P < 0.0001) (for pancreatic cancer-specific survival: lung vs liver metastases: P < 0.0001; distant nodal vs liver metastases: P < 0.0001). Multivariate analysis revealed that age < 65 years, white race, being married, female gender; surgery to the primary tumor and surgery to the metastatic disease were associated with better overall survival and pancreatic cancer-specific survival. CONCLUSION Pancreatic adenocarcinoma patients with isolated liver metastases have worse outcomes compared to patients with isolated lung or distant nodal metastases. Further research is needed to identify the highly selected subset of patients who may benefit from local treatment of the primary tumor and/or metastatic disease.

Abstract
BACKGROUND Pancreatic cancer is a highly aggressive malignancy and will become the second leading cause of cancer-related death in the USA and also in Germany by 2030. Furthermore, the majority of patients with pancreatic ductal adenocarcinoma (PDAC) will present with distant metastases, limiting surgical management in this population as there is little evidence available to support surgical or ablative treatment options for advanced-stage disease. However, highly selected patients suffering from synchronous and metachronous oligometastatic PDAC may potentially benefit from a surgical resection with an acceptable morbidity. METHODS This review summarizes and discusses the current literature on the management of oligometastatic disease regarding PDAC, focusing on para-aortic lymph nodes as well as isolated hepatic and pulmonary metastases. RESULTS AND CONCLUSION In order to further investigate the feasibility and efficacy of such an approach, a prospective multicenter trial, in which survival and quality of life after metastatic resection and systemic chemotherapy is evaluated, has to be initiated. Additionally, local and locoregional ablation techniques or stereotactic body radiation therapy as therapeutic options for isolated metastases in PDAC need further research in order to determine their significance and benefit.

Abstract
The incidence of pancreatic adenocarcinoma (PDAC) has steadily increased over the past several decades. The majority of PDAC patients will present with distant metastases, limiting surgical management in this population. Hepatectomy and pulmonary metastasectomy (PM) has been well established for colorectal cancer patients with isolated, resectable hepatic or pulmonary metastatic disease. Recent advancements in effective systemic therapy for PDAC have led to the selection of certain patients where metastectomy may be potentially indicated. However, the indication for resection of oligometastases in PDAC is not well defined. This review will discuss the current literature on the surgical management of metastatic disease for PDAC with a specific focus on surgical resection for isolated hepatic and pulmonary metastases.

Abstract
A 68-year-old man presented to our hospital with a 1-month history of slowly progressing altered mental status and gait disturbance. Magnetic resonance imaging and abdominal computed tomography revealed advanced pancreatic cancer (PC) with brain and para-aortic lymph node metastases. Gross total resection of the brain metastatic tumor was performed. Although symptoms improved, the patient died 3 months postoperatively. In general, the prognosis for PC patients with brain metastasis is very poor. Surgical resection of brain metastasis may play a very limited role in allowing long-term survival of patients for whom the primary PC is controlled or with particular oncocytic-type tumors.

Abstract
About 10% of all cancer patients will develop brain metastases during advanced disease progression. Interestingly, the vast majority of brain metastases occur in only three types of cancer: Melanoma, lung and breast cancer. In this review, we focus on summarizing the prognosis and impact of surgical resection of brain metastases originating from gastrointestinal cancers such as esophageal, gastric, pancreatic and colorectal cancer. The incidence of brain metastases is <1% in pancreatic and gastric cancer and <4% in esophageal and colorectal cancer. Overall, prognosis of these patients is very poor with a median survival in the range of only months. Interestingly, a substantial number of patients who had received surgical resection of brain metastases showed prolonged survival. However, it should be taken into account that all these studies were not randomized and it is likely that patients selected for surgical treatment presented with other important prognostic factors such as solitary brain metastases and exclusion of extra-cranial disease. Nevertheless, other reports have demonstrated long-term survival of patients upon resection of brain metastases originating from gastrointestinal cancers. Thus, it appears to be justified to consider aggressive surgical approaches for these patients.
