Pancreatic Neuroendocrine Tumours

Background: The incidence of pancreatic Neuroendocrine Tumours (pNETs) has increased considerably in the last few decades. The characteristic features of this tumour and the development of new investigative and therapeutic methods had a great impact on its management. Objective: The aim of this review is to investigate the outcome of Peptide Receptor Radionuclide Therapy (PRRT) in the treatment of pancreatic neuroendocrine tumours. Methods: A comprehensive literature search strategy was used based on two databases (SCOPUS, and PubMed). We considered all studies published in English, evaluating the use of PRRT (177Luteciuim- DOTA-conjugated peptides and 90Yetrium- DOTA- conjugated peptides) in the treatment of pancreatic neuroendocrine tumours as a standalone entity or as a subgroup within the wider category of Gastroenteropancreatic Neuroendocrine Tumours (GEP NETs). Results: PRRT was found to be an effective treatment modality as a monotherapy or in combination with other therapies in the treatment of non-operable and metastatic pNETs where other options are limited. Complete response was reported to be between 2-6% while partial response was achieved in up to 60% of cases. Survival analysis was also impressive. Progression Free Survival (PFS) reached a mean of 34 months and Overall Survival (OS) of 53 months. PRRT also proved to improve patients’ Quality of Life (QoL). Acute and sub-acute side effects like nephrotoxicity and haematotoxicity are usually mild and reversible. Conclusion: PRRT is well tolerated and effective treatment option for non-operable and/or metastatic pNETs. Side effects are usually mild and reversible. Larger randomized controlled trails need to be done to compare PRRT with other treatment modalities and to provide more detailed guidelines regarding patient selections, the choice of PRRT, follow up and response assessment to maximum potential benefit.

Abstract Background and Aims Endo-sponge [Braun Medical] assisted early surgical closure [ESC] is an effective treatment to control pelvic sepsis after ileal pouch-anal anastomosis [IPAA] leakage, and became standard treatment in our centre from 2010 onwards. The aim of this cohort study was to assess the long-term pouch function of ulcerative colitis [UC] patients treated with ESC or conventional management [CM] for anastomotic leakage after IPAA. Methods Consecutive patients who underwent an IPAA for UC between 2002 and 2017 were included. Patients treated with ESC [2010–2017] or CM [2002–2009] for anastomotic leakage were compared with control patients without anastomotic leakage of the corresponding time period. Main endpoints were long-term pouch function on a 3-point scale and pouch failure, as measured with the validated pouch dysfunction score questionnaire. Results Some 280 of 334 patients [84%] returned the pouch dysfunction questionnaire, of whom 18 were treated with ESC and 22 with CM for anastomotic leakage. Control cohorts included 133 [2010–2017] and 107 patients [2002–2009]. Between ESC-treated patients and control patients, pouch function [p = 0.647] and pouch failure rates [0/18 versus 5/133, p >0.99] were similar. CM resulted in worse pouch function [p = 0.016] and a higher pouch failure rate [5/22 versus 5/107, p = 0.013] compared with control patients. Conclusions ESC, in contrast to CM, for IPAA leakage in UC patients is associated with preservation of pouch function and preclusion of pouch failure, probably due to early and effective treatment of pelvic sepsis.

Long-term fluoroquinolone-associated disability (FQAD) after fluoroquinolone (FQ) antibiotic therapy appears in recent years as a significant medical and social problem, because patients suffer for many years after prescribed antimicrobial FQ treatment from tiredness, concentration problems, neuropathies, tendinopathies, and other symptoms. The knowledge about the molecular activity of FQs in the cells remains unclear in many details. The effective treatment of this chronic state remains difficult and not effective. The current paper reviews the pathobiochemical properties of FQs, hints the directions for further research, and reviews the research concerning the proposed treatment of patients. Based on the analysis of literature, the main directions of possible effective treatment of FQAD are proposed: (a) reduction of the oxidative stress, (b) restoring reduced mitochondrion potential ΔΨm, (c) supplementation of uni- and bivalent cations that are chelated by FQs and probably ineffectively transported to the cell (caution must be paid to Fe and Cu because they may generate Fenton reaction), (d) stimulating the mitochondrial proliferation, (e) removing FQs permanently accumulated in the cells (if this phenomenon takes place), and (f) regulating the disturbed gene expression and enzyme activity.

Peptide receptor radionuclide therapy (PRRT) has been recognized as a promising therapy against neuroendocrine tumors (NETs). The use of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) in NETs has been a matter of controversy. The purpose of this study was to evaluate the long-term survival and efficacy of a second PRRT course with 177Lu-DOTATE in patients with advanced gastroenteropancreatic (GEP) NETs. Furthermore, the value of 18F-FDG PET/CT in these patients was evaluated. 40 patients with GEP NETs who underwent two PRRT courses with 177Lu-DOTATATE and combined examinations with 68Ga-DOTA-TOC and 18F-FDG PET/CT were evaluated. After the second PRRT course, two patients (5.0%) were in partial remission, 21 patients (52.5%) in stable disease and 17 patients (42.5%) had progressive disease. The median overall survival was 122.10 months. After the second PRRT course, the median overall survival was significantly higher (p = 0.033) in the 18F-FDG-negative group compared to the 18F-FDG-positive group (145.50 versus 95.06 months, respectively). The median time to progression was 19.37 months. In conclusion, a second PRRT course with 177Lu-DOTATE is an effective treatment approach for GEP NET patients with disease progression. A change in 18F-FDG status after PRRT may predict the disease course and survival. Patients who are 18F-FDG-negative have a significantly longer overall survival than those who are 18F-FDG-positive.

4112 Background: As demonstrated in the primary analysis of the phase 3 NETTER-1 trial, 177Lu-DOTATATE significantly prolonged progression-free survival (PFS) versus high-dose long-acting octreotide, with a HR of 0.18 (95% CI: 0.11, 0.29; p < 0.0001), in patients with advanced, progressive, well-differentiated, somatostatin receptor-positive midgut neuroendocrine tumors (NETs). Here we report final overall survival (OS) for NETTER-1. Methods: In this international open-label trial, eligible patients were randomized to receive either four cycles of 177Lu-DOTATATE 7.4 GBq (200 mCi) every 8 ± 1 weeks plus long-acting octreotide 30 mg or high-dose long-acting octreotide 60 mg every 4 weeks (control arm), both on top of best supportive care. After disease progression on randomized treatment or completion of an 18-month treatment period, patients in both arms entered long-term follow-up and could receive further anti-cancer treatment as recommended by their physicians. The primary endpoint was PFS per RECIST 1.1 and OS was a key secondary endpoint. Primary intention-to-treat analysis of OS was prespecified to take place after 158 deaths or 5 years after the last patient was randomized, whichever occurred first. Results: Of 231 randomized patients, 101/117 (86.3%) in the 177Lu-DOTATATE arm and 99/114 (86.8%) in the control arm entered long-term follow-up. Final analysis occurred 5 years after the last patient was randomized, following 142 deaths, with a median follow-up of more than 76 months. During long-term follow-up, 41/114 (36%) of patients in the control arm received subsequent radioligand therapy (“cross-over”), the majority (22.8%) within 24 months. Median OS was 48.0 months (95% CI: 37.4, 55.2) in the 177Lu-DOTATATE arm and 36.3 months (95% CI: 25.9, 51.7) in the control arm. HR was 0.84 (95% CI: 0.60, 1.17) with p = 0.30 (unstratified 2-sided log-rank test). A total of 2/112 (1.8%) 177Lu-DOTATATE treated patients in the study developed myelodysplastic syndrome (MDS). No new cases of MDS or acute leukemia were reported in the long-term follow-up. Overall, no new safety signals emerged during long-term follow-up. Conclusions: Median OS was 48.0 months in the 177Lu-DOTATATE arm of the NETTER-1 trial and 36.3 months in the control arm. This difference was not statistically significant, potentially impacted by a high rate (36%) of cross-over of patients in the control arm to radioligand therapy after progression. In overall conclusion, the NETTER-1 study demonstrated that 177Lu-DOTATATE yielded a clinically and statistically significant improvement in PFS as a primary endpoint (HR: 0.18, p < 0.0001) as well as a clinically meaningful trend towards improvement in median OS of 11.7 months. No new safety signals emerged during the 5-year long-term follow-up. Clinical trial information: NCT01578239.

Acute gout requires rapid, effective treatment. Colchicine, non-steroidal anti-inflammatories, and corticosteroids are all effective; the choice of agent is dictated by the patient’s co-morbidities and concomitant medications. Interleukin-1 inhibitors are effective, but the high cost precludes routine use, and long-term safety data for repeated use are lacking.

Lithium is a unique drug. In more than 60 years of observation, it showed its multiple important clinical properties in treating mania, stabilizing mood alterations, preventing suicide and protecting from neurodegeneration. It was also the most extensively studied drug in psychiatry. Nevertheless, it is generally underprescribed. Specifically, lithium is virtually not considered in the treatment of patients affected by mixed affective states. Lithium is not suggested for the acute treatment of mixed affective states and is considered to be less effective than other mood stabilizers in the long-term management of these patients. The main reason why lithium has no indication for mixed states is the “lack of evidence.” Actually, there are several reasons to consider lithium as an effective treatment in patients with mixed affective states.
