Adrenocortical carcinoma (ACC) is a rare but lethal malignancy with few reliable prognostic markers. FDG-PET metabolic parameters have been shown to predict survival in several cancers. The objective was to determine if metabolic tumor volume (MTV), total lesion glycolysis (TLG), and maximum standardized uptake value (SUVmax) could serve as prognostic markers in patients with ACC. ⋯ Patients with ACC and a high whole body MTV, TLG, and SUVmax have a worse prognosis and OS. Measurement of whole body MTV and TLG may be helpful for guiding therapy for patients with ACC.

Randomized Controlled Trial
Development and Validation of a Disease-Specific Instrument to Measure Diet-Targeted Quality of Life for Postoperative Patients with Esophagogastric Cancer.
Patients who have undergone esophagectomy or gastrectomy have certain dietary limitations because of changes to the alimentary tract. This study attempted to develop a psychometric scale, named "Esophago-Gastric surgery and Quality of Dietary life (EGQ-D)," for assessment of impact of upper gastrointestinal surgery on diet-targeted quality of life. ⋯ The EGQ-D scale has good contents and psychometric validity and can be used to evaluate disease-specific instrument to measure diet-targeted quality of life for postoperative patients with esophagogastric cancer.

Preoperative/neoadjuvant therapy (NT) is increasingly utilized for the treatment of pancreatic ductal adenocarcinoma (PDAC). However, little data exist regarding information on the use of additional postoperative therapy following NT. The lymph node ratio (LNR) is a prognostic marker of oncologic outcomes after NT and resection. In this study, we evaluated the effectiveness of postoperative therapy following NT, stratified by LNR. ⋯ Postoperative chemotherapy after NT in patients with low LNR is associated with improved oncologic outcomes.

A significant proportion of women who have breast-conserving surgery (BCS) subsequently undergo re-excision or proceed to mastectomy. This study aimed to identify factors associated with residual disease after repeat surgery and to determine their effect on ipsilateral breast tumor recurrence (IBTR) and survival. ⋯ A higher risk of IBTR seen after re-excision was associated with residual disease. Overall survival was similar regardless of repeat surgery and residual findings.

Circumferential resection margins (CRM) for esophageal cancer (EC), defined by the College of American Pathologists (CAP; >0 mm) or the Royal College of Pathologists (RCP; >1 mm) as tumor-free (R0), are based on a surgery-alone approach. We evaluated the usefulness of both definitions in current practice with neoadjuvant chemoradiotherapy (nCRT). ⋯ nCRT affected the CRM cutoff values. After nCRT, the CRM R0 according to the CAP was only prognostic for 2-year LRFS. However, in the surgery-alone group, it was prognostic for both the 2-year DFS and LRFS.
