As the world embarks on mass vaccination for COVID-19, we are beginning to encounter unintended dilemmas in imaging oncology patients; particularly with regards to FDG PET/CT. In some cases, vaccine-related lymphadenopathy and FDG uptake on PET/CT can mimic cancer and lead to confounding imaging results. These cases where findings overlap with cancer pose a significant dilemma for diagnostic purposes, follow-up, and management leading to possible treatment delays, unnecessary repeat imaging and sampling, and patient anxiety. These cases can largely be avoided by optimal coordination between vaccination and planned imaging as well as preemptive selection of vaccine administration site. This coordination hinges on patient, oncologist, and radiologists' awareness of this issue and collaboration. Through close communication and patient education, we believe this will eliminate significant challenges for our oncology patients as we strive to end this pandemic., (Published by Elsevier Ltd.)

Background: Long-term incidence of endocrine and exocrine insufficiency after pancreatectomy is poorly described. We analyze the long-term risks of pancreatic insufficiency after pancreatectomy., Methods: Subjects who underwent pancreatectomy from 2002 to 2012 were identified from a prospective database (n = 227). Subjects who underwent total pancreatectomy or pancreatitis surgery were excluded. New post-operative endocrine and exocrine insufficiency was defined as the need for new pharmacologic intervention within 1000 days from resection., Results: 28 (16%) of 178 subjects without pre-existing endocrine insufficiency developed post-operative endocrine insufficiency: 7 (25%) did so within 30 days, 8 (29%) between 30 and 90 days, and 13 (46%) after 90 days. 94 (43%) of 214 subjects without pre-operative exocrine insufficiency developed exocrine insufficiency: 20 (21%) did so within 30 days, 29 (31%) between 30 and 90 days, and 45 (48%) after 90 days. Adjuvant radiation was associated with new endocrine insufficiency. On multivariate regression, pancreaticoduodenectomy and chemotherapy were associated with a greater risk of exocrine insufficiency., Conclusion: Reporting 30-day functional outcomes for pancreatic resection is insufficient, as nearly 45% of subjects who develop disease do so after 90 days. Reporting of at least 90-day outcomes may more reliably assess risk for post-operative endocrine and exocrine insufficiency., (Copyright © 2016 International Hepato-Pancreato-Biliary Association Inc.

Background: Recent studies have shown adjuvant therapy improves outcomes from pancreatic cancer (PC). This study investigates receipt and timing of PC treatments, and association with outcomes., Methods: The analysis cohort consisted of patients with newly-diagnosed PC at a single institution over 5 years. Primary Endpoints were (i) receipt of recommended therapy, and (ii) overall survival (OS)., Results: Among 102 patients, 52 underwent resection. Out of 36 localized resected and 16 locally advanced resected (LAR) patients, 26 and 13, respectively, received adjuvant therapy. Six of the latter group received neoadjuvant therapy. Median OS for resected patients was 15.7 months (range 0.6-51.4), compared with 7.7 for unresected patients (range 0.4-32.0) (P < 0.001), and 14.0 months for patients with resection alone (range 0.6-24.4) vs. 16.1 for patients who also received adjuvant therapy (range 3.2-51.4) (P= 0.027). Out of 46 patients undergoing up-front resection, 33 had R0 surgical margins. For the six LAR patients undergoing neoadjuvant therapy, all margins were R0., Conclusion: After resection, a substantial proportion of patients do not receive adjuvant therapy, and have worse survival. In this study, neoadjuvant treatment increased both the proportion of patients receiving all components of recommended therapy and the R0 resection rate.

This session focused on issues related to implementation of randomized clinical trials in palliative care studies. Topics discussed included what kinds of clinical sites and patient populations were suitable, what types of clinical investigators (clinical specialty) should be involved in or lead the studies, what multisite mechanisms could be used to conduct the trials, and what funding issues were related to these studies. A trial of operative versus nonoperative management for small bowel obstruction caused by recurrent intra-abdominal cancer was considered. The feasibility of such a trial was examined in terms of whether there was "equipoise" for a majority of likely investigators in the field around the trial question, what other issues might impact accrual to the trial, and how many patients would be required to answer which of these two treatment arms was better. This last question is related to selection of a primary endpoint for the trial and was a modestly contentious issue for the trial design group. Both sensible compromises in endpoint selection and the education of the community of investigators for a particular randomized trial in palliative care are crucial steps for successful implementation. A major conclusion of this session is that implementation considerations are intimately related to the architecture of a specific trial and should be addressed practically and early in the design phase of any randomized trial addressing a palliative care question. In this respect, randomized trials in palliative care are no different than in other fields.
