Positron emission tomography/magnetic resonance imaging for the diagnosis and differentiation of pancreatic tumors

Conclusion The integration of PET/MR imaging could be used to efficiently diagnose whether the pancreatic tumor was benign or malignant. The SUVmax/ADC was the most efficient metric, while it could not help in the differentiation of pancreatic cancer.

Here we present the case of a 76-year-old woman with pancreatic cancer receiving epidural analgesia for chronic cancer pain treatment. Attempts of running the epidural catheter sequentially resulted in unexpected and extensive sensory block together with sympathicolysis but insufficient pain control. Finally, after 3 failed attempts of epidural catheter placements with insufficient pain control and uncommon neurological signs, a magnetic resonance imaging (MRI) scan of the spine was ordered. The MRI showed subdural catheter displacement with extensive liquid accumulation in the subdural space and consequent significant spi...

Conclusions The recent, first randomized clinical trial demonstrated overall and progression free survival benefits after SBRT to oligometastatic disease which supports prior retrospective case series (6). The spine is a common site of metastatic bone disease, and as high quality data continue to mature, along with completion of additional randomized clinical trials, it is expected that utility of SBRT to the spine will increase in the future. Spine SBRT is unique due to the requirement of sharp dose falloff to prevent serious neurologic morbidity. With recent advances in radiotherapy planning, robotic patient positionin...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

Conclusion We have reviewed the literature and identified blood biomarkers with the highest discriminative abilities as determined by operating characteristics in four commonly encountered clinical situations: diagnosing concussion, predicting the need for a CT scan after mTBI, predicting delayed recovery after mTBI, and predicting poor outcome after sTBI. The top performers in each category may provide insight into pathogenic mechanisms of TBI that most influence the measured endpoint. Nonetheless, many challenges remain before these biomarkers can be incorporated into clinical practice. In particular, it remains unclear...

This report supports that the novel mutation of RNF139 p.Q650R probably serve as a key role in HBs progression. Introduction Central nervous system hemangioblastomas (HBs) are benign tumors which usually occur in cerebellum (1), and the pathogenesis of HBs is still unknown. According to the revised World Health Organization (WHO) classification of tumors of the nervous system published in 2000, HBs were classified to the tumors of uncertain histogenesis. The morphology code of the International Classification of Diseases for Oncology (ICD-O)is 9161/1, grade I. HBs are composed of mesenchymal cells and abundant capi...

This study aims to, first, determine suitable gating windows with respect to effectiveness (low interplay effect) and efficiency (high duty cycles). Second, it investigates whether beam gating allows a better mitigation of the interplay effect along the treatment course than free-breathing irradiations. Based on synthetic 4D-CTs, generated by warping 3D-CTs with vector fields extracted from time-resolved magnetic resonance imaging (4D-MRI) for 8 pancreatic cancer patients, 4D dose calculations (4DDC) were performed to analyze the duty cycle and homogeneity index HI=d5/d95 for four different gating scenarios.
