The accuracy of endoscopic ultrasound for restaging esophageal carcinoma after chemoradiation therapy

Abstract

The study of fault detection and diagnosis of electrical machines, in particular induction motors, as well as the teaching of their behavior requires practical experience in this field. To provide this experience to the students this paper presents an experimental system that can be used with a standard industrial electrical induction machine. This system is based on only one healthy induction machine that is operated under faulty operating modes. Several fault types such as stator winding faults, bearing faults, or broken bars can be tested. The developed system also allows testing the behavior of the electrical machine for different load types. Several typical loads in which the torque depends of time or speed were implemented. The system is based on computer equipment with a DSPIC, a testing system and an induction machine. © 2010 Wiley Periodicals, Inc. Comput Appl Eng Educ 20: 611–618, 2012

Prospective comparison of the perceived preoperative computed tomographic, endosonographic and histopathological stage of oesophageal cancer related to body mass indices

“…Moreover, 63 patients (38%) received preoperative neoadjuvant chemotherapy, and these patients' tumours may have been down-staged, further influencing the potential accuracy of both the CT and EUS stage. Indeed, the strengths of agreement between both EUS T and N stage were better in patients who had undergone surgery alone (T stage Kw=0.696 and N stage Kw 0.569) compared with patients who had received neoadjuvant chemotherapy (T stage Kw=0.364, and N stage Kw=0.459, respectively), which is consistent with previous reports [2,9,[17][18][19][20]. Nevertheless, the study also has strengths in that it represents an original prospective study of 9 years of pragmatic specialist multidisciplinary upper GI practice by experienced clinicians with wellaudited and published results [9,11,21].…”

Nomogram for predicting the benefit of neoadjuvant chemoradiotherapy for patients with esophageal cancer: A SEER‐Medicare analysis

“…12 Meanwhile, currently available techniques for clinical TNM staging, especially restaging, are unreliable. 7,21 However, the survival benefit of CRT is likely not distributed evenly across all patients. Those patients who achieve a pCR, with no residual tumor identifiable in the surgical specimen, or even those with a partial response after neoadjuvant CRT, have a better prognosis than those that have no appreciable or minimal response to CRT.…”

“…Moreover, large number of patients did not have follow-up EUS evaluation after CRT. This finding was attributed to unsatisfactory accuracy of EUS in response evaluation after CRT, particularly in a neoadjuvant setting [44,45,46]. In addition, some patients could not have EUS follow-up due to their poor general conditions, and others chose to refuse evaluations including EUS.…”
