Intraductal papillary mucinous neoplasms (IPMNs) are deadly exocrine mucinous tumors. Currently the molecular features and diagnostic markers of IPMNs are not well understood. In this study, we performed microRNA (miRNA) profiling assays to study the potential roles of miRNAs in IPMNs using 78 cases of IPMN patients and controls. When comparing the miRNA expression between IPMN patient samples and controls, we found that miR-210, miR-223, miR-221, miR-155 and miR-187 were differentially expressed in normal pancreas and IPMNs...

Breast cancer is the prime cause for cancer mortality in women worldwide. The importance of diverse natural and dietary agents to reduce the risk of developing breast cancer is well established. Berberine, a natural isoquinoline alkaloid found in many medicinal plants is widely used in traditional Indian and Chinese medicine. Because of its capability to seize the cell cycle and induce apoptosis of numerous malignant cells, berberine has received considerable attention as a potential anticancer agent. In the present study, breast cancer was induced in Sprague Dawley (SD) rats by intragastric administration of 7, 12-dimethylbenz[a]anthracene (DMBA) at a dose of 80mg/kg of body weight...

Hypoxia-inducible factor-2α (HIF-2α) plays an important role in increasing cancer progression and distant metastasis in a variety of tumour types. We aimed to investigate its biological function and clinical significance in human pancreatic ductal adenocarcinoma (PDAC). A total of 283 paired PDAC tissues and adjacent normal tissues were collected from patients who underwent surgery or biopsy at Sun Yat-sen Memorial Hospital between February 2004 and October 2016. In this study, we noted that HIF-2α expression was significantly up-regulated in PDAC, positively associated with disease stage, lymph-node metastasis and patient survival, and identified as an independent prognostic factor of PDAC patients...

Early detection of breast cancer through screening can lower breast cancer mortality rates and reduce the burden of this disease in the population. In most western countries, mammography screening starting from age 50 is recommended. However, there is debate about whether breast cancer screening should be extended to younger women. This systematic review provides an overview of the evidence from RCT's on the benefits and harms of breast cancer screening with mammography in women aged 40 to 49 years. The quality of the evidence for each outcome was appraised using the GRADE approach...

Non-invasive biomarkers for early pancreatic ductal adenocarcinoma (PDAC) diagnosis and disease risk stratification are greatly needed. We conducted a nested case-control study within the Prospective Investigation into Cancer and Nutrition (EPIC) cohort to evaluate pre-diagnostic microRNAs (miRs) as biomarkers of subsequent PDAC risk. A panel of eight miRs (miR-10a, -10b, -21-3p, -21-5p, -30c, -106b, -155, and -212) based on previous evidence from our group was evaluated in 225 microscopically confirmed PDAC cases and 225 controls matched on center, sex, fasting status, and age/date/time of blood collection...

BACKGROUND AND PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) are administered to manage pain typically found in patients suffering from pancreatitis. NSAIDs also display anti-proliferative activity against cancer cells, however their effects in normal, untransformed cells is poorly understood. Here we evaluated whether NSAIDs inhibit proliferation of pancreatic acinar cells during the development of acute pancreatitis. EXPERIMENTAL APPROACH: The NSAIDs ibuprofen and diclofenac were administered to C57BL/6 mice after induction of pancreatitis with serial injection of cerulein...

For years, lobular carcinoma In Situ (LCIS) has been considered a high-risk marker for developing breast cancer. It is well known that ductal carcinoma In Situ is a precursor for the development of invasive ductal carcinoma, and ductal carcinoma In Situ is reported to be present in invasive ductal carcinoma in at least 40 per cent of cases. A similar relationship between LCIS and invasive lobular carcinoma (ILC) remains in question. This study evaluates the incidence of synchronous LCIS and ILC at our institution...

Early detection tests for pancreatic ductal adenocarcinoma (PDAC) are needed. Since a hypothetical screening test would be applied during antecedent clinical encounters, we sought to define the variability in health care utilization leading up to the PDAC diagnosis. This was a retrospective cohort study that included patients diagnosed with PDAC in the Indianapolis area between 1999-2013 with at least one health care encounter during the 36-month antecedent period (n = 1,023). Patients were classified by unique patterns of care utilization using a group-based trajectory model...

BACKGROUND: At present, it is difficult to predict which patients with ductal carcinoma-in-situ (DCIS) will subsequently develop frank invasive breast cancer (IDC). A recent survey by our group has shown that NY-ESO-1 and MAGEA are both expressed in DCIS. This study was aimed at determining whether expression of these antigens was related to the later development of IDC. RESULTS: 14 of 42 (33%) of patients developed invasive breast cancer during the follow up period...

Pancreatic ductal adenocarcinoma (PDAC) is usually detected late in the disease process. Clinical workup through imaging and tissue biopsies is often complex and expensive due to a paucity of reliable biomarkers. We used an advanced multiplexed plasmonic assay to analyze circulating tumor-derived extracellular vesicles (tEVs) in more than 100 clinical populations. Using EV-based protein marker profiling, we identified a signature of five markers (PDAC(EV) signature) for PDAC detection. In our prospective cohort, the accuracy for the PDAC(EV) signature was 84% [95% confidence interval (CI), 69 to 93%] but only 63 to 72% for single-marker screening...

Ductal eccrine carcinoma (DEC) is a rare sweat gland carcinoma with ductular differentiation. Clinically, it is characterized by a slowly growing, hardened plaque or nodule predominantly located on the head and neck. Histologically, DEC shares similar features to invasive breast carcinoma, thus causing great diagnostic challenges. We report a 69-year-old woman who presented with a hardened plaque on the axilla. A skin biopsy was performed and metastatic invasive breast carcinoma could not be ruled out. Complete excision and further workup were subsequently conducted, leading to the diagnosis of estrogen receptor positive DEC with associated axillary lymph node metastases...

A pancreatic ductal adenocarcinoma (PDAC), obtained from a patient, was grown orthotopically in the pancreatic tail of nude mice to establish a patient-derived orthotopic (PDOX) model. Seven weeks after implantation, PDOX nude mice were divided into the following groups: untreated control (n = 7); gemcitabine (100 mg/kg, i.p., once a week for 2 weeks, n = 7); cobimetinib (5 mg/kg, p.o., 14 consecutive days, n = 7); trametinib (0.3 mg/kg, p.o., 14 consecutive days, n = 7); trabectedin (0.15 mg/kg, i.v., once a week for 2 weeks, n = 7); temozolomide (25 mg/kg, p...

Many studies have suggested that disialogangliosides, GD2 and GD3, are involved in the development of various tumor types. However, the functional relationships between ganglioside expression and cancer development or aggressiveness are not fully described. GD3 is upregulated in approximately half of all invasive ductal breast carcinoma cases, and enhanced expression of GD3 synthase (GD3S, alpha-N-acetylneuraminide alpha-2,8-sialyltransferase) in estrogen receptor-negative breast tumors, was shown to correlate with reduced overall patient survival...

Calponin 2 plays an important role in regulating actin cytoskeleton, which is critical for cell division and migration. Previous studies have demonstrated that calponin 2 inhibits prostate cancer cell proliferation and metastasis. However, the role of calponin 2 in pancreatic tumor growth, metastasis and patient survival remains unclear. Here, we demonstrate that the level of calponin 2 is a positive prognostic factor for patients with pancreatic ductal adenocarcinoma (PDAC). Patients with high calponin 2 expression in the tumor presented less lymph node metastasis and longer survival...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) often infiltrates to the adjacent major vasculatures; however, direct invasion of PDAC to the inferior vena cava (IVC) is uncommon. CASE PRESENTATION: We report our experience with three cases of PDAC directly invading the IVC wall. All three patients underwent pancreatoduodenectomy along with wedge resection of the IVC wall without severe postoperative complications. Histopathological studies revealed tumor infiltration to the adventitia of the IVC...

Pancreatic cancer is one of the deadliest human malignancies and lack of effective diagnostic and therapeutic methods. Accumulating evidence suggests that the neurotensin (NT) and neurotensin receptors (NTRs) play key roles in pancreatic adenocarcinoma growth and survival. In this study, we not only evaluate the NTR1 expression in pancreatic cancer patient samples, but also explore the PET and fluorescence imaging of NTR1 expression in pancreatic cancer animal models. The NTR1 expression was evaluated by immunohistochemistry staining in clinical patient tissue samples with pancreatic ductal adenocarcinoma, insulinoma, and pancreatitis...
