Quality of death in patients in advanced chronic liver disease and cancer patients managed by gastroenterologists in Portugal: are we doing it right?

INTRODUCTION: The incidence of chronic progressive diseases is rising and investment on quality of death and dying is of utmost importance to minimize physical and emotional suffering. There is still a gap in palliative care (PC) between patients with cancer and those with advanced chronic liver disease (ACLD). Our objectives were to characterize clinical attitudes and therapeutic interventions and to evaluate the differences in end-of-life care between inpatients with cancer and ACLD under gastroenterology care. METHODS: Retrospective cohort study, including patients with cancer or ACLD who died in a Gastroenterology department between 2012 and 2021. Demographic characteristics, clinical and endoscopic procedures and symptom control were compared between the groups. RESULTS: From 150 patients, 118 (78.7%) died with cancer and 32 (21.3%) died from ACLD without concomitant hepatocellular carcinoma. ACLD patients were more frequently male ( P  = 0.001) and younger ( P  = 0.001) than patients with cancer. Median time of hospitalization in the last month of life was 16 days for both groups. Discussion of prognosis with the patient was more frequent for cancer patients (35.6% versus 3.2%, P  < 0.001). Referral to PC occurred in 18.8% and 61% of the patients with ACLD and cancer respectively ( P  < 0.001). Endoscopic procedures were performed in half of the patients and were more likely to be unsuccessful in those with cancer. CONCLUSION: Clinical decisions were different between groups in terms of PC access and discussion of prognostic with the patient. It is urgent to define and implement metrics of quality of death and dying to prevent potentially inappropriate treatment.

Role of Endoscopic Biopsies and Morphologic Features in Predicting Microsatellite Instability Status in Gastric Cancer: A Multicenter Comparative Study of Endoscopic Biopsies and Surgical Specimens.

Evaluation of mismatch repair (MMR) protein and microsatellite instability (MSI) status plays a pivotal role in the management of gastric cancer (GC) patients. In this study, we aimed to evaluate the accuracy of gastric endoscopic biopsies (EBs) in predicting MMR/MSI status and to uncover histopathologic features associated with MSI. A multicentric series of 140 GCs was collected retrospectively, in which EB and matched surgical specimens (SSs) were available. Laurén and WHO classifications were applied and detailed morphologic characterization was performed. EB/SS were analyzed by immunohistochemistry (IHC) for MMR status and by multiplex polymerase chain reaction (mPCR) for MSI status. IHC allowed accurate evaluation of MMR status in EB (sensitivity: 97.3%; specificity: 98.0%) and high concordance rates between EB and SS (Cohen κ=94.5%). By contrast, mPCR (Idylla MSI Test) showed lower sensitivity in evaluating MSI status (91.3% vs. 97.3%), while maintaining maximal specificity (100.0%). These results suggest a role of IHC as a screening method for MMR status in EB and the use of mPCR as a confirmatory test. Although Laurén/WHO classifications were not able to discriminate GC cases with MSI, we identified specific histopathologic features that are significantly associated with MMR/MSI status in GC, despite the morphologic heterogeneity of GC cases harboring this molecular phenotype. In SS, these features included the presence of mucinous and/or solid components ( P =0.034 and <0.001) and the presence of neutrophil-rich stroma, distant from tumor ulceration/perforation ( P <0.001). In EB, both solid areas and extracellular mucin lakes were also discriminating features for the identification of MSI-high cases ( P =0.002 and 0.045).

Performance of Immunohistochemical and Molecular Methods in Detecting Microsatellite Instability in Gastric Cancer: A Multicenter Study.

INTRODUCTION: Microsatellite instability (MSI) is an important prognostic molecular biomarker for gastric cancer (GC). MSI status may be detected by immunohistochemistry (IHC) for mismatch repair (MMR) proteins and polymerase chain reaction (PCR). Idylla™ MSI assay has not been validated for GC but may prove to be a valid alternative. METHODS: In a series of 140 GC cases, MSI status was evaluated by IHC for MLH1, PMS2, MSH2, and MSH6; gold-standard pentaplex PCR panel (PPP) (BAT-25, BAT-26, NR-21, NR-24, and NR-27); and Idylla. Statistical analysis was performed using SPSS 27.0. RESULTS: PPP identified 102 microsatellite stable (MSS) cases and 38 MSI-high cases. Only 3 cases showed discordant results. Compared with PPP, the sensitivity was 100% for IHC and 94.7% for Idylla. Specificity was 99% for IHC and 100% for Idylla. MLH1 IHC alone showed sensitivity and specificity of 97.4% and 98.0%, respectively. IHC identified three indeterminate cases; all were MSS according to PPP and Idylla. CONCLUSION: IHC for MMR proteins represents an optimal screening tool for MSI status in GC. If resources are limited, isolated MLH1 evaluation may constitute a valuable option for preliminary screening. Idylla may help detect rare MSS cases with MMR-loss and define MSI status in indeterminate cases.

Groove Pancreatitis: Clinical Cases and Review of the Literature.

Introduction: Groove pancreatitis (GP) is a type of chronic segmental pancreatitis that affects the pancreatoduodenal groove area, and it is often misdiagnosed. Outflow obstruction of the minor papilla associated with alcohol consumption seems to be the main pathophysiological mechanism, and it affects mainly middle-aged males. Symptoms include nausea and postprandial vomiting from gastric outlet obstruction, weight loss, and abdominal pain. Despite modern advances, such as radiological and endoscopic methods, distinction between GP and pancreatic cancer remains a challenge, and histological examination is sometimes necessary. When a diagnosis can be obtained without a surgical specimen, management can be conservative in the absence of acute or chronic complications. Case Presentation: The authors present 2 clinical cases which portray the diagnostic workup and management decisions of this entity. Discussion/Conclusion: GP is a clinical entity, offering diagnostic and therapeutic challenges. Imaging exams are crucial in the diagnosis and follow-up, but surgery may be necessary in a significant number of cases due to the incapacity to rule out malignancy.

Introdução: A pancreatite da goteira (PG) constitui uma forma de pancreatite crónica segmentar, que afeta a área da goteira pancreatoduodenal, sendo frequentemente subdiagnosticada. O mecanismo fisiopatológico principal parece ser a obstrução ao fluxo da papila minor relacionada com o consumo de álcool. Esta patologia ocorre mais frequentemente em homens entre a 4a e 5a décadas de vida. A maioria dos doentes apresenta sintomas como náuseas e vómitos pós-prandiais, perda ponderal e dor abdominal. Apesar do desenvolvimento atual dos métodos radiológicos e endoscópicos, a distinção entre PG e neoplasia pancreática constitui um desafio diagnóstico e a avaliação histológica pode ser necessária. Se for possível obter o diagnóstico sem intervenção cirúrgica, o tratamento pode ser conservador na ausência de complicações agudas e crónicas. Apresentação do caso: Apresentamos 2 casos clínicos que demonstram a abordagem diagnóstica e a gestão de decisões terapêuticas nesta entidade. Discussão/Conclusão: A PG é uma entidade clínica que oferece com diagnóstico e terapêutica desafiantes. Apesar da importância crucial dos exames imagiológicos no diagnóstico e seguimento, a incapacidade de excluir um processo maligno torna necessária a intervenção cirúrgica numa parte significativa dos casos.
