Cross-sectional prevalence of pancreatic cystic lesions in patients with acromegaly, a single-center experience

AbstractPurposeAcromegaly is a disease associated with an increased risk for several kinds of neoplasms including colon and thyroid cancer. Although the association between acromegaly and pancreatic neoplasms has not been elucidated, it has recently been reported thatGNAS gene mutations were found in 58% of intraductal papillary mucinous neoplasms (IPMNs), which are representative pancreatic cystic lesions, suggesting a link between IPMNs and acromegaly. To assess the prevalence of pancreatic cystic lesions in patients with acromegaly, we performed a retrospective cross-sectional single institute study.MethodsThirty consecutive acromegalic patients (20 females and 10 males; mean age, 60.9  ± 11.9 years) who underwent abdominal contrast-enhanced computed tomography or magnetic resonance imaging between 2007 and 2015 at Kobe University Hospital were recruited. We also analyzed the relationship between presence of pancreatic cystic lesions and somaticGNAS mutations in pituitary tumors.ResultsSeventeen of 30 (56.7%) patients studied had pancreatic cystic lesions. Nine of 17 patients (52.9%) were diagnosed with IPMNs based on imaging findings. These results suggest that the prevalence of IPMNs may be higher in acromegalic patients in acromegalic patients than historically observed in control patients (up to 13.5%). In patients with pancreatic cystic lesions, the mean patient age was higher and the duration of disease was longer than in those without pancr...

It has been estimated that more than one-third of patients are diagnosed when CRC has already spread to the lymph nodes. One out of five patients is diagnosed with metastatic CRC. The stage of diagnosis influences treatment outcome and survival. Notwithstanding the recent advances in multidisciplinary ma...

Along with its outstanding effects, Gemcitabine has some side effects, which may cause suffering to patients. Herein we developed, a novel but simple method for the selective and sensitive quantitative determination of Gemcitabine drug based upon measuring the fluorescence quenching of functionalized Au doped quantum dots (QDs) in biological samples. The TGA capped Au doped CdTe quantum dot...

Meanwhile, activation of nuclear factor-kappaB (NF-κB) has been found to induce autophagy in several types of human diseases including cancer and cardiac diseases. However, it is still unknown whether NF-κB mediates autophagy activation in PAH, and whethe...
