Abstract

Introduction: Duodenal neuroendocrine tumours (D-NETs) have a low incidence; however, their diagnosis has been increasing. Features such as tumour location, size, type, histological grade, and stage were used to adapt the treatment to either endoscopic (ER) or surgical (SR) resections. There is no consensus regarding the definitive treatment. The authors' study aimed to describe the management of non-metastatic, well-differentiated D-NETs in France and its impact on patient survival. Methods: A registry-based multicenter study using prospectively collected data between 2000 and 2019, including all patients managed for non-metastatic G1 and G2 D-NETs, was conducted in the GTE group. Results: A total of 153 patients were included. Fifty-eight benefited from an ER, and 95 had an SR. No difference in recurrence-free survival (RFS) was observed regardless of treatment type. There was no significant difference between the two groups (ER vs. SR) in terms of location, size, grade, or lymphadenopathy, regardless of the type of incomplete resection performed or regarding the pretherapeutic assessment of lymph node invasion in imaging. The surgery allowed for significantly more complete resection (patients with R1 resection in the SR group: 9 vs. 14 in the ER group, P <0.001). Among the 51 patients with positive lymph node dissection after SR, tumour size was less than or equal to 1 cmin 25 cases. Surgical complications were more numerous (P= 0.001). In the subgroup analysis of G1-G2 D-NETs between 11 and 19 mm, there was no significant difference in grade (P =0.977) and location (P =0.617) between the two groups (ER vs. SR). No significant difference was found in both morphological and functional imaging, focusing on the pre-therapeutic assessment of lymph node invasion (P =0.387). Conclusion: Regardless of the resection type (ER or SR) of G1-G2 non-metastatic D-NETs, as well as the type of management of incomplete resection, which was greater in the ER group, long-term survival results were similar between ER and SR. Organ preservation seems to be the best choice owing to the slow evolution of these tumours. [ABSTRACT FROM AUTHOR]

Abstract

This ENETS guidance paper aims to provide practical advice to clinicians for the diagnosis, treatment and follow‐up of functioning syndromes in pancreatic neuroendocrine tumours (NET). A NET‐associated functioning syndrome is defined by the presence of a clinical syndrome combined with biochemical evidence of inappropriately elevated hormonal levels. Different hormonal syndromes can be encountered in pancreatic NET patients, including insulinoma, gastrinoma as well as the rare glucagonoma, VIPoma, ACTHoma, PTHrPoma, carcinoid syndrome, calcitoninoma, GHRHoma and somatostatinoma. The recommendations provided in this paper focus on the biochemical, genetic and imaging work‐up as well as therapeutic management of the individual hormonal syndromes in well‐differentiated, grade 1‐3, functioning NET with the primary tumour originating in the pancreas, and for specific subtypes also in the duodenum.

Abstract

Background In advanced pancreatic ductal adenocarcinoma (aPDAC), there is no consensual strategy for second-line chemotherapy (L2). Better discrimination of overall survival (OS) may help clinical decision-making. We aimed to predict OS from the beginning of L2 and to assess the benefit from chemotherapy among the identified risk groups. Methods Analyses were derived from all consecutive aPDAC patients treated at Besancon University Hospital, Besancon, France, between January 2003 and December 2013 (n = 462). The association of 50 parameters with OS was evaluated using univariate and multivariable Cox analyses. Based on the final model, a prognostic nomogram and score were developed and externally validated. Patients in the external validation cohort who received L2 (n = 163) were treated at three French institutions between January 2010 and April 2016. All statistical tests were two-sided. Results In the development cohort, 395 patients (85.5%) were eligible for L2, of which 261 (66.1%) were treated. Age, smoking status, liver metastases, performance status, pain, jaundice, ascites, duration of first-line, and type of L2 regimen were identified as independent prognostic factors for OS in L2. The score determined three groups with median OS of 11.3 months (95% confidence interval [CI] = 9.1 to 12.9 months), 3.6 months (95% CI = 2.6 to 4.7 months), and 1.4 months (95% CI = 1.2 to 1.7 months), for low-, intermediate-, and high-risk groups, respectively ( P < .001). By applying the score in the population eligible for L2 but untreated, the chemotherapy benefit was statistically significant across all groups, but with a magnitude of the effect decreased statistically significantly from low- to high-risk groups ( P = .001 for treatment and risk groups interaction term). The ability of the score to discriminate OS was confirmed in the external validation cohort. Conclusions This prognostic nomogram and score in patients with aPDAC can accurately predict OS before administration of L2 and may help clinicians in their therapeutic decisions.

Abstract

A case of hepatic abscess that developed secondary to a foreign body migration is reported herein. In most published cases, the diagnosis is done after failure of medical treatment or recurrence of the abscess. CT-scan findings may lead to an early diagnosis, like in this case. The patient was treated by percutaneous abscess drainage and adapted antibiotherapy. Because of remarkable co-morbid conditions, no removal surgery was performed. No recurrence of the abscess could be observed after eighteen months of follow up. Foreign body is a rare cause of liver abscess that may not be ignored by clinicians. Although removal surgery is the mainstay of its treatment, a medical approach could be attempted with efficacy.

Abstract

Purpose To investigate whether liver enhancing tumor burden (LETB) assessed at contrast-enhanced CT indicates early response and helps predict survival outcomes in patients with multifocal neuroendocrine liver metastases (NELM) after intra-arterial treatment. Materials and Methods This retrospective study included patients with NELM who underwent intra-arterial treatment with transarterial embolization (TAE) or chemoembolization (TACE) between April 2006 and December 2018. Tumor response in treated NELM was evaluated by using the Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST (mRECIST). LETB was measured as attenuation 2 SDs greater than that of a region of interest in the nontumoral liver parenchyma. Overall survival (OS); time to unTA(C)Eable progression, defined as the time from the initial treatment until the time when intra-arterial treatments were considered technically unfeasible, either not recommended by the multidisciplinary tumor board or until death; and hepatic and whole-body progression-free survival (PFS) were evaluated using multivariable Cox proportional hazards analyses, the Kaplan-Meier method, and log-rank test. Results The study included 119 patients (mean age, 60 years ± 11 [SD]; 61 men) who underwent 161 treatments. A median LETB change of -25.8% best discriminated OS (83 months in responders vs 51 months in nonresponders; P = .02) and whole-body PFS (18 vs 8 months, respectively; P < .001). A -10% LETB change best discriminated time to unTA(C)Eable progression (32 months in responders vs 12 months in nonresponders; P < .001) and hepatic PFS (18 vs 8 months, respectively; P < .001). LETB change remained independently associated with improved OS (hazard ratio [HR], 0.56), time to unTA(C)Eable progression (HR, 0.44), hepatic PFS (HR, 0.42), and whole-body PFS (HR, 0.47) on multivariable analysis. Neither RECIST nor mRECIST helped predict patient outcome. Conclusion Response according to LETB change helped predict survival outcomes in patients with NELM after intra-arterial treatments, with better discrimination than RECIST and mRECIST.

Abstract

Background Cancer patients are thought to have an increased risk of developing severe Coronavirus Disease 2019 (COVID-19) infection and of dying from the disease. In this work, predictive factors for COVID-19 severity and mortality in cancer patients were investigated. Patients and Methods In this large nationwide retro-prospective cohort study, we collected data on patients with solid tumours and COVID-19 diagnosed between March 1 and June 11, 2020. The primary endpoint was all-cause mortality and COVID-19 severity, defined as admission to an intensive care unit (ICU) and/or mechanical ventilation and/or death, was one of the secondary endpoints. Results From April 4 to June 11, 2020, 1289 patients were analysed. The most frequent cancers were digestive and thoracic. Altogether, 424 (33%) patients had a severe form of COVID-19 and 370 (29%) patients died. In multivariate analysis, independent factors associated with death were male sex (odds ratio 1.73, 95%CI: 1.18-2.52), ECOG PS ≥ 2 (OR 3.23, 95%CI: 2.27-4.61), updated Charlson comorbidity index (OR 1.08, 95%CI: 1.01-1.16) and admission to ICU (OR 3.62, 95%CI 2.14-6.11). The same factors, age along with corticosteroids before COVID-19 diagnosis, and thoracic primary tumour site were independently associated with COVID-19 severity. None of the anticancer treatments administered within the previous 3 months had any effect on mortality or COVID-19 severity, except cytotoxic chemotherapy in the subgroup of patients with detectable SARS-CoV-2 by RT-PCR, which was associated with a slight increase of the risk of death (OR 1.53; 95%CI: 1.00-2.34; p = 0.05). A total of 431 (39%) patients had their systemic anticancer treatment interrupted or stopped following diagnosis of COVID-19. Conclusions Mortality and COVID-19 severity in cancer patients are high and are associated with general characteristics of patients. We found no deleterious effects of recent anticancer treatments, except for cytotoxic chemotherapy in the RT-PCR-confirmed subgroup of patients. In almost 40% of patients, the systemic anticancer therapy was interrupted or stopped after COVID-19 diagnosis., Highlights • A total of 1289 patients with solid tumours and COVID-19 were analysed. • Mortality and COVID-19 severity were mainly driven by patient general characteristics. • Overall, we found no deleterious effects of recent anticancer treatments on mortality. . • Systemic anticancer treatment was interrupted or stopped in 39% of patients.

Abstract

Background: Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis. The POLO trial showed that olaparib (PARP inhibitor) improved progression-free survival (PFS) but not overall survival (OS), when used as maintenance therapy after ≥ 16 weeks of disease control with first-line platinum-based chemotherapy in patients with germline (g) BRCA 1 or 2 pathogenic variants (PV) metastatic PDAC. However, real-world data on the effectiveness of olaparib are missing., Methods: Patients with unresectable PDAC associated with somatic (s) or (g)BRCA1/2 and (g)non-BRCA-HRD PV (i.e. other homologous recombination deficiency/HRD genes) who were treated with olaparib between 2020-2023 were included. The primary objective was to describe treatment patterns. Secondary exploratory objectives included OS and PFS in patients treated with olaparib according to the POLO trial or not, OS and PFS in patients with (g)HRD PV-associated PDAC versus (s)PVs, olaparib safety profile and factors associated with olaparib poor outcomes., Results: Among 85 patients, 45.9 % received olaparib as defined by the POLO trial. No difference in OS and PFS was observed between patients who received olaparib according to the POLO trial versus not. Patients with (g)HRD PV-associated PDAC had better OS compared to others (22.3 versus 10.5 months, p = 0.038). Factors associated with olaparib poor outcomes included a high neutrophil-to-lymphocyte ratio and the use of olaparib outside the recommendations of the POLO trial. Few grade ≥ 3 adverse events were reported (9.4 %)., Conclusion: Patients with (g)HRD PV-associated PDAC had longer OS than those with (s)HRD PV. Olaparib use beyond the scope of the POLO trial was associated with poor outcomes., Competing Interests: Declaration of Competing Interest APe declares speaker’s engagement from Servier; consulting/advisory role for Amgen; travel grant from Ipsen, Merk and Servier.

Abstract

Introduction: Duodenal neuroendocrine tumours (D-NETs) have a low incidence; however, their diagnosis has been increasing. Features such as tumour location, size, type, histological grade, and stage were used to adapt the treatment to either endoscopic (ER) or surgical (SR) resections. There is no consensus regarding the definitive treatment. The authors' study aimed to describe the management of non-metastatic, well-differentiated D-NETs in France and its impact on patient survival., Methods: A registry-based multicenter study using prospectively collected data between 2000 and 2019, including all patients managed for non-metastatic G1 and G2 D-NETs, was conducted in the GTE group., Results: A total of 153 patients were included. Fifty-eight benefited from an ER, and 95 had an SR. No difference in recurrence-free survival (RFS) was observed regardless of treatment type. There was no significant difference between the two groups (ER vs. SR) in terms of location, size, grade, or lymphadenopathy, regardless of the type of incomplete resection performed or regarding the pre-therapeutic assessment of lymph node invasion in imaging. The surgery allowed for significantly more complete resection (patients with R1 resection in the SR group: 9 vs. 14 in the ER group, P <0.001). Among the 51 patients with positive lymph node dissection after SR, tumour size was less than or equal to 1 cm in 25 cases. Surgical complications were more numerous ( P =0.001). In the sub-group analysis of G1-G2 D-NETs between 11 and 19 mm, there was no significant difference in grade ( P =0.977) and location ( P =0.617) between the two groups (ER vs. SR). No significant difference was found in both morphological and functional imaging, focusing on the pre-therapeutic assessment of lymph node invasion ( P =0.387)., Conclusion: Regardless of the resection type (ER or SR) of G1-G2 non-metastatic D-NETs, as well as the type of management of incomplete resection, which was greater in the ER group, long-term survival results were similar between ER and SR. Organ preservation seems to be the best choice owing to the slow evolution of these tumours., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Abstract

Objectives: Imaging features of pancreatic acinar cystic transformation (ACT) have been published. We aimed to describe the clinical and radiological characteristics of patients with a presumed pancreatic ACT diagnosis, reappraising the value of these published imaging criteria., Materials and Methods: Single-center retrospective study (2003-2021) of consecutive patients with a presumed diagnosis of ACT as suggested by the local expert multidisciplinary case review board. Patients without available imaging (CT or MRI) for review were excluded. Patients were classified into "certain" ACT (if ≥ 2 imaging criteria and no differential diagnosis) or "uncertain" ACT (if ≥ 1 imaging criteria and suggested differential diagnoses)., Results: Sixty-four patients (35 males, [55%]) were included. ACT was considered "certain" for 34 patients (53%) and "uncertain" for 30 patients (47%). The number of ACT criteria did not differ between groups, with 91.2% of patients with ≥ 3 ACT imaging criteria in the "certain" group vs 93.3% in the "uncertain" group (p = 0.88). In the "uncertain" group, the main suggested differentials were branch-duct intraductal papillary mucinous neoplasm (18/30 patients, 60%), calcifying chronic pancreatitis (8/30 patients, 27%), both (three patients, 10%) and serous cystadenoma (one patient, 3%). Calcifications were significantly more frequent in the "uncertain" group (89% vs 63% in the "certain" group, p = 0.02)., Conclusion: Published ACT imaging criteria are frequently associated with features suggesting differential diagnoses. They appear insufficient to reach a final diagnosis in a subset of patients., Clinical Relevance Statement: ACT displays a heterogeneous morphological imaging presentation challenging the non-invasive diagnostic work-up. Physicians' and radiologists' awareness of this entity is important to better understand its natural history and improve non-invasive diagnostic criteria., Key Points: The criteria to help diagnose ACT are frequently associated with features suggestive of differentials. The main alternatives suggested when ACT diagnosis was "uncertain" were branch-duct intraductal papillary mucinous neoplasm and calcifying chronic pancreatitis. Published ACT diagnostic imaging criteria can be insufficient for a definite non-invasive diagnosis., (© 2024. The Author(s), under exclusive licence to European Society of Radiology.)

49. Pancreatic neuroendocrine tumors in French VHL mutation carriers: a multicentric retrospective study.

Author

Abstract

Background: Von Hippel-Lindau disease (VHL) is a rare autosomal dominant hereditary cancer-predisposition syndrome caused by germline pathogenic variants (PV) in VHL gene. It is associated with a high penetrance of benign and malignant vascular tumors in multiples organs, including pancreatic neuroendocrine tumors (PanNETs), whose long-term natural history is ill-known., Methods: Patients with both documented germline PV in VHL gene and PanNETs included in the French PREDIR database between 1995 and 2022 were included. Primary endpoint was the proportion of patients with PanNET-related metastases and secondary endpoint was overall survival (OS). Genotype/phenotype correlations were studied., Results: We included 121 patients with 259 PanNETs. Median age at diagnosis was 38 years. Median follow-up was 89.5 months. PanNET surgical resection was performed in 51 patients. Overall, 29 patients (24%) had metastases (5 synchronous, 10 metachronous), with a higher risk in case of larger PanNET size (p=0.0089; best threshold 28 mm) and grade 2 PanNET (p=0.048), and a pejorative prognostic impact (p=0.043). Patients with PV in VHL exon 1 had larger PanNETs (p=0.018), more often metastatic disease (48% vs 11.5%; p < 0.001) and a trend toward shorter OS (p=0.16)., Conclusion: The risk of metastases associated to VHL-related PanNETs remains low (24%) but increases with tumor size >28 mm, higher grade and in case of PV located VHL exon 1. These data might help improving the management of these patients, who should be referred to an expert center., (© The Author(s) 2024.

Abstract

Background: Solid pseudopapillary neoplasms of the pancreas (SPNP) are rare tumors predominantly in young women. We report the largest single-center cohort study comparing resection of SPNP by laparoscopic approach (LA) and the open approach (OA)., Method: Between 2001 and 2021, 102 patients (84% women, median age: 30) underwent pancreatectomy for SPNP and were retrospectively studied. Demographic, perioperative, pathological, early and the long-term results were evaluated between patients operated by LA and those by OA., Results: Population included 40 LA and 62 OA. There were no significant differences in demographics data between the groups. A preoperative biopsy by endoscopic ultrasound was performed in 45 patients (44%) with no difference between the groups. Pancreatoduodenectomy (PD) was less frequently performed by LA (25 vs 53%, p = 0.004) and distal pancreatectomy (DP) was more frequently performed by LA (40 vs 16%, p = 0.003). In the subgroup analysis by surgical procedure, LA-PD was associated with one mortality, less median blood loss (180 vs 200 ml, p = 0.034) and fewer harvested lymph nodes (11 vs 15, p = 0.02). LA-DP was associated with smaller median tumor size on imaging (40 vs 80mm, p = 0.048), shorter surgery (135 vs 190 min, p = 0.028), and fewer complications according to the median comprehensive complication index score (0 vs 8.7, p = 0.048). LA-Central pancreatectomy was associated with shorter surgery (160 vs 240, p = 0.037), less median blood loss (60 vs 200, p = 0.043), and less harvested lymph nodes (5 vs 2, p = 0.025). After a median follow-up of 60 months, two recurrences (2%) were observed and were unrelated to the approach., Conclusions: The LA for SPNP appears to be safe, should be applied cautiously in case of PD for large lesion, and was not associated with recurrence., (© 2024.
