Role of (F-18) Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in the Prediction of Response to Neoadjuvant Therapy in Esophageal Cancer: Correlation with Pathological Response and Survival.

Purpose: The purpose of this study is to assess the correlation between metabolic response with fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and pathological response in patients with locally advanced esophageal cancer treated with neoadjuvant chemoradiotherapy and to study FDG-PET parameters for the prediction of pathological response and outcome.

Methods: Twenty-five patients with locally advanced esophageal cancer underwent two FDG-PET/CT scans for initial staging and after neoadjuvant chemoradiotherapy. FDG uptake in the primary tumor was calculated in both scans (SUVmax, SULpeak, and TLG).

[Deep venous thrombosis as a marker of tumor recurrence].

Background And Objective: There is a bidirectional association between neoplasia and venous thromboembolism (VTE). However, whether this association has an impact in tumor recurrence is unknown. The aim of the study is to assess the incidence of cancer recurrence after diagnosis of VTE and determine if VTE could be a marker for cancer recurrence.
