| 1 | Positron emission tomography as predictor of rectal cancer response during or following neoadjuvant chemoradiation显示文摘Positron emission tomography (PET) shows great promise as a tool to evaluate the effectiveness of rectal cancer neoadjuvant therapy as it has demonstrated high predictive value in several studies. Creating a standardized method of using PET has the potential to reduce ineffective treatments. However, relevant studies have been heterogenous in approach, making any unified standard difficult to establish. PET related parameters used to assess treatment response include magnitude and change of standard uptake value, total lesion glycolysis, and visual response. Finding the best evaluation interval and parameters to use for interpreting PET results in the neoadjuvant treatment of rectal cancer needs additional study. | Shane Hopkins Marwan Fakih Gary Y Yang | 2010 | World Journal of Gastrointestinal Oncology2010，2，5： | 0 |
| 2 | Positron emission tomography's changing significance in the treatment of esophageal cancer显示文摘Incidence of esophageal cancer has been rising,and Positron Emission Tomography(PET) is one tool that has shown utility and promise as a tool for staging,treatment response,and prognosis.PET delivery has evolved over time and is now frequently registered with a CT scan at the time of acquisition.However,resolution and confounders such as post-treatment radiation changes may limit clinical utility.PET has been shown to be helpful in staging,especially in evaluating for distant metastases.PET acquired after chemoradiation may give important prognostic information that can guide additional treatment decisions.Studies have had substantial variability in recommendations for the timing and manner of using PET for this purpose,and additional study is needed. | Shane Hopkins Gary Yang | 2009 | World Journal of Gastrointestinal Oncology2009，1，1： | 0 |
