RESUMO
Background: Multidisciplinary team (MDT) meetings aim to optimize patient management. We evaluated the impact of MDT discussions on the management and diagnosis of focal pancreatic lesions in a single tertiary center. Methods: All patients with an initial diagnosis of solid or cystic pancreatic lesion discussed in our institution's MDT meeting on pancreatic diseases between January 1, 2020, and December 31, 2021, were included. The impact of MDT discussion on patient management, defined as a modification of the initially proposed therapeutic plan after MDT discussion, as well as the criteria leading to this modification, were the primary outcomes. Impact on diagnosis was the secondary outcome. Results: A total of 522 patients were included. Of these, 185 (35.4%) and 337 (64.6%) had an initial diagnosis of cystic or solid lesion, respectively. The most common referral query was regarding the management plan (349/522; 66.9%). Endoscopy was the procedure most often proposed before MDT discussion (109/522; 20.9%). Overall, the MDT discussion led to modification of the management plan in 377/522 patients (72.2%), with a statistically significant difference between cystic and solid lesions (63.2% vs. 77.2%; P<0.001). Management modifications were mainly driven by revision of cross-sectional radiological images. MDT discussion led to modification of the diagnosis in 92/522 patients (17.6%), with a significant difference regarding cystic lesions (35.7% vs. 7.7%; P<0.001). Conclusion: MDT discussion impacts the management of patients with cystic and solid pancreatic lesions, leading to a modification of the initially proposed management in two-thirds of them, mainly through revision of cross-sectional imaging.
RESUMO
AIM: Evaluation of safety and efficacy of selective balloon-occluded transarterial chemoembolization using polyethylene glycol embolizing microspheres in patients with hepatocellular carcinoma. MATERIALS & METHODS: Twenty-four consecutive patients were included in this monocentric prospective trial. Adverse events were evaluated at 24 h and 1 month. Imaging response according to modified response evaluation criteria in solid tumors was assessed at 1, 3 and 6 months. RESULTS: The median time of follow-up was of 22.8 months (interquartile range (IQR) 17.38-26.22). Clinical grade 1/2 toxicities (0% >grade 2) were reported in 25.7% of patients, with abdominal pain being the most frequent complication (17.1%). No 30-days mortalities or liver decompensation were observed. The 1-month follow-up MRI showed an overall response rate of 74.3%. CONCLUSION: Balloon-occluded transarterial chemoembolization was shown to be safe and effective.
RESUMO
Pancreatic ductal adenocarcinoma carries a dismal prognosis. Both chemotherapy and targeted therapies have been disappointing when administered to unselected populations. Recently, progress has been made in our understanding of the genomic landscape of this cancer which displays remarkable heterogeneity suggesting a reorientation of management and research strategies based on molecular characterization and adapted personalized therapy. Resectable disease offers new opportunities for translational research through functional imaging response evaluation and tumor tissue acquisition before and after neoadjuvant therapy. There is urgent need for clinical trials based on molecular profiling in pancreatic ductal adenocarcinoma. In this review we discuss opportunities and limitations of these new strategies, underlining the importance of tissue acquisition and integration of molecular biomarkers in future molecularly driven clinical trials.
RESUMO
BACKGROUND: Surgery is a curative treatment for patients with locally advanced colon cancer, but recurrences are frequent for those with stage III disease. FOLFOX adjuvant chemotherapy has been shown to improve recurrence-free survival and overall survival by more than 20% and is nowadays considered a standard of care. However, the vast majority of patients will not benefit from receiving cytotoxic drugs because they have either already been cured by surgery or because their tumor cells are resistant to the chemotherapy, for which predictive factors are still not available. METHODS/DESIGN: PePiTA is a prospective, multicenter, non-randomised trial built on the hypothesis that preoperative chemosensitivity testing using FDG-PET/CT before and after one course of FOLFOX can identify the patients who are unlikely to benefit from 6 months of adjuvant FOLFOX treatment for stage III colon cancer. DISCUSSION: PePiTA is the first study to use the primitive tumor chemosensitivity assessed by metabolic imaging as a guidance for adjuvant therapy in colon cancer. It could pave the way for tailoring the treatment and avoiding useless toxicities for the patients and inadequate expenses for the society. It could also give an interesting insight into tumoral heterogeneity, resistance to chemotherapy, genetic predisposants to oxaliplatin toxicity and immune response to cancer.
