Setup management for stereotactic body radiation therapy of patients with pancreatic cancer treated via the breath-hold technique

ConclusionsThis study demonstrates that intra-fraction targeting errors can be within 2mm while inter-fraction shifts from free-breathing spine to ABC breath-hold target can be as high as 8mm. Values that deviate significantly would need further investigation to rule out factors such as local progression, bowel gas or fiducial shift prior to treatment.

Did you know diabetes affects your mental health? From depression to relationship problems or mood swings, too much or too little glucose (sugar) circulating in the blood can trigger behavior and thought patterns that may seem unrelated to how much insulin is released by your pancreas. Out of control glucose levels influence how you feel and make decisions, your beliefs and, yes, your attitude, a very necessary component of your overall care.  The U.S. Centers for Disease Control and Prevention (CDC) states less than half the number of people with diabetes who have depression get treated, which leads to worsening stat...

Abstract It is already known that adult height is a factor associated with an increased risk of colon cancer and postmenopausal breast cancer, pancreatic cancer, premenopausal breast cancer, and ovarian cancer. However, the association between adult height and lung cancer incidence remains unclear. The purpose of the present study was to examine the association between adult height and the risk of lung cancer incidence in the Japanese population. We analyzed data for 43,743 men and women who were 40-64 years old at the baseline in 1990. We divided the participants into quintiles based on height at the baseline. Co...

This study is aimed at obtaining the pathway in the microbial tumorigenesis of PC. Microarray datasets GSE27890, GSE46234, and GSE17610 were downloaded from the GEO (Gene Expression Omnibus) database. Differential analysis was performed for every single gene chip using the R software package ("Limma" package), and functional enrichment analyses were carried out by DAVID (Database for Annotation, Visualization and Integrated Discovery). The PPI (protein-protein interaction) network was constructed with the Search Tool for the Retrieval of Interacting Genes (STRING). The survival analysis was performed by GEPIA and...

Conclusions: Most cancers may be insensitive to social development. Internal factors, including aging, may be a key factor for the occurrence of cancer. PMID: 32462031 [PubMed - in process]

CONCLUSIONS: People with schizophrenia do not have a higher overall incidence of cancer than people in the general population. However, there are significant differences in the risk of specific cancer types overall and by sex calling for efforts to develop disease-specific prevention programmes. In people with schizophrenia, higher risk generally occurs in those

AbstractRemarkable progress has been made in treating pancreatic cancer over the past century, including refinement of our surgical techniques and improvements in adjuvant and neoadjuvant therapies. Despite these advances, the incidence of pancreatic cancer is rising globally, and it remains a deadly disease. In this review, we highlight the historical perspectives of pancreatic cancer treatment and outline the areas of future advancement that will assist progression towards better outcomes. Areas of future advancement include improving prevention strategies and early detection, refining our molecular understanding of panc...

We report the first crystal structure of an oncogenic mutant, KRAS G12V-H-REV107. This peptide was shown to interact with KRAS G12V in the guanosine diphosphate (GDP)-bound inactive state and to form a stable complex, blocking the activation function of KRAS. We showed that the peptide acted as an inhibitor of mutant KRAS targets by [α-32P] guanosine triphosphate (GTP) binding assay. The H-REV107 peptide inhibited pancreatic cancer and colon cancer cell lines in cell proliferation assay. Specially, the H-REV107 peptide can suppress pancreatic tumor growth by reduction of tumor volume and weight in xenotransplanta...

Previously documented arguments, in favor of the suspected impact of a seed and soil mechanism, in the development and progression of isolated pancreatic metastasis of renal cell carcinomas (isPM) are: (1) uniform and independent from the side of the primary tumor distribution of isPM within the pancreas and, (2) the similar survival rates for singular and multiple isPM. In addition, the present study adds new arguments that further confirm the importance of an seed and soil mechanism in isPM: (1) Within the singular isPM, the size of the metastasis does not affect the overall survival; (2) Within the group of multiple isP...

This study elucidates the molecular basis of this multi-agent regimen, focusing on the role of MET signaling. Since MET activation stems from its interaction with hepatocyte growth factor (HGF), which is typically secreted by fibroblasts, we developed heterotypic PDAC microtumor models that recapitulate these interactions. In these models, MET signaling can be constitutively activated through paracrine and autocrine mechanisms. Photodynamic therapy caused significant elevations in HGF secretion by fibroblasts, suggesting it plays a complex role in the modulation of the paracrine HGF–MET signaling cascade in desmo...
