Quality of life in patients with gastroenteropancreatic tumours: A systematic literature review

Younger Age and Parenchyma-Sparing Surgery Positively Affected Long-Term Health-Related Quality of Life after Surgery for Pancreatic Neuroendocrine Neoplasms

(1) Background: Patients with pancreatic Neuroendocrine Neoplasms (PanNENs) often have a long overall survival. We evaluated determinants of quality of life (QoL) after surgery for PanNENs. (2) Methods: Patients operated on for a PanNEN in our center (1990-2021) received three EORTC QoL questionnaires (QLQ-C30, QLQ-GI.NET21, QLQ-PAN26). Six domains were selected as outcome variables (global QoL, physical function -PF, social function -SF, disease-related worries -DRWs, pain, upper-gastrointestinal (GI) symptoms) and evaluated in relation to the clinical variables. Statistical analysis was performed using R software v 4.2.2. (3) Results: One hundred and four patients enrolled showed a good global QoL (median 83.3). Old age was a determinant of worse global QoL (p 0.006) and worse PF (p 0.003). Multiple comorbidities (p 0.002) and old age (p 0.034) were associated with pain, while male gender was related to better PF (p 0.007) and less pain (p 0.012). Patients who had undergone parenchyma-sparing surgery demonstrated better PF (p 0.037), better SF (p 0.012), and less upper-GI symptoms (p 0.047). At multivariable analysis, age (p 0.005) and type of surgery (p 0.028) were confirmed as determinants of global QoL. (4) Conclusions: In patients operated on for a PanNEN, a good HRQoL is generally reported; notably, younger age and parenchyma-sparing surgery seem to positively affect HRQoL.

Consideration of quality-of-life in the treatment decision-making for patients with advanced gastroenteropancreatic neuroendocrine tumors

INTRODUCTION

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a complex and heterogenous family of solid malignancies that originate from neuroendocrine tissue in the gastrointestinal tract or pancreas. Most patients diagnosed with GEP-NETs present with advanced or metastatic disease, and quality of life (QoL) is often an important priority when selecting treatments for these patients. Patients with advanced GEP-NETs often experience a substantial and persistent symptom burden that undermines their QoL. Addressing a patient's individual symptoms through judicious selection of treatment may improve QoL.

AREAS COVERED

The objectives of this narrative review are to summarize the impact of advanced GEP-NETs on patient QoL, assess the potential value of current treatments for maintaining or improving patient QoL, and offer a clinical framework for how these QoL data can be translated to inform clinical decision-making for patients with advanced GEP-NETs.

EXPERT OPINION

Patients with advanced GEP-NETs experience a significant and persistent symptom burden that impacts their daily lifestyle, activities, work life, and financial health, leading to erosion of their QoL. Ongoing and future studies incorporating longitudinal QoL assessments and head-to-head treatment evaluations will further inform the incorporation of QoL into clinical decision-making.

CT-based radiomics to distinguish progressive from stable neuroendocrine liver metastases treated with somatostatin analogues: an explorative study

BACKGROUND

Accurate response evaluation in patients with neuroendocrine liver metastases (NELM) remains a challenge. Radiomics has shown promising results regarding response assessment.

PURPOSE

To differentiate progressive (PD) from stable disease (SD) with radiomics in patients with NELM undergoing somatostatin analogue (SSA) treatment.

MATERIAL AND METHODS

A total of 46 patients with histologically confirmed gastroenteropancreatic neuroendocrine tumors (GEP-NET) with ≥1 NELM and ≥2 computed tomography (CT) scans were included. Response was assessed with Response Evaluation Criteria in Solid Tumors (RECIST1.1). Hepatic target lesions were manually delineated and analyzed with radiomics. Radiomics features were extracted from each NELM on both arterial-phase (AP) and portal-venous-phase (PVP) CT. Multiple instance learning with regularized logistic regression via LASSO penalization (with threefold cross-validation) was used to classify response. Three models were computed: (i) AP model; (ii) PVP model; and (iii) AP + PVP model for a lesion-based and patient-based outcome. Next, clinical features were added to each model.

RESULTS

In total, 19 (40%) patients had PD. Median follow-up was 13 months (range 1-50 months). Radiomics models could not accurately classify response (area under the curve 0.44-0.60). Adding clinical variables to the radiomics models did not significantly improve the performance of any model.

CONCLUSION

Radiomics features were not able to accurately classify response of NELM on surveillance CT scans during SSA treatment.

Fatigue and quality of life in patients with neuroendocrine neoplasia

INTRODUCTION

Neuroendocrine Neoplasms (NEN) are rare tumours arising in the gastro-intestinal tract or lungs. Poor health related quality of life (HRQoL) is associated with the carcinoid syndrome (CS), but fatigue is also important. We aimed to quantify HRQoL and fatigue in out-patients with NEN.

METHODS

In a cross-sectional study, we included 231 patients with NEN (G1-G3). We used pre-validated questionnaires MFI-20, EQ-5D-5L and 85% responded. We collected clinical, biochemical, imaging, and pathology data from Electronic Patient files. Normative values for fatigue and HRQoL were derived from background populations.

RESULTS

Median age was 68 years (range 21-91) and 52% were male. Patients with NEN reported more fatigue and worse HRQoL compared to the background population (p < .05). Cured patients reported higher HRQoL than patients with current disease, and patients with high grade neoplasms (G2-G3) reported more anxiety and depression compared to patients with low grade G1 disease (p < .05). The CS resulted in a 9% relative loss in Quality Adjusted Life Years compared to patients without CS. (p < .05). More than 50% of patients with CS reported problems with usual activities, pain/discomfort, and anxiety/depression. Overall, 36% of patients with NEN were fatigued and 92% of these had psychological fatigue. Younger patients (<65 years) experienced more fatigue than older patients (p < .05).

CONCLUSION

Patients with NEN report significantly lower HRQoL and more fatigue compared to the background population. Especially, patients with CS had pain, discomfort, anxiety, and depression and a relative reduction in HRQoL. However, compared to other cancer types, patients with NEN experience less fatigue.

Relationship between somatostatin receptor expressing tumour volume and health-related quality of life in patients with metastatic GEP-NET

For patients with gastroenteropancreatic neuroendocrine tumours (GEP-NET), health-related quality of life (HRQoL) is important. Meanwhile, whether tumour volume is associated with HRQoL is unknown. Hence, the aim of this study was to assess if total somatostatin receptor expressing tumour volume is correlated with HRQoL in patients with metastatic GEP-NET. Some 71 patients were included in the study. HRQoL and NET-specific symptoms were assessed with EORTC QLQ-C30 and EORTC GI.NET21. A summary score was calculated from the output of the QLQ-C30. Total somatostatin receptor expressing tumour volume was retrospectively evaluated on somatostatin receptor imaging with positron emission tomography-computed tomography (⁶⁸ Ga-DOTA-TATE/TOC PET-CT) in each patient. Simple and multiple linear regression were used to evaluate the correlation between tumour volume and HRQoL, controlling for potential confounders. No correlation was found between total somatostatin receptor expressing tumour volume and QLQ-C30 summary score. Weak positive correlations were found between total tumour volume and the specific symptoms dyspnoea, diarrhoea and flushing. To the best of our knowledge, this is the first study to evaluate the association between total somatostatin expressing tumour volume and HRQoL. Our results indicate that, while tumour volume is weakly associated with symptom severity of the carcinoid syndrome, other factors might impact more on overall HRQoL.

Health-related quality of life in patients with advanced well-differentiated pancreatic and extrapancreatic neuroendocrine tumors treated with surufatinib versus placebo: Results from two randomized, double-blind, phase III trials (SANET-p and SANET-ep)

AIM

To investigate the health-related quality of life (HRQoL) of patients who had neuroendocrine tumors (NETs) from SANET trials.

METHODS

Eligible patients were randomized in a 2:1 ratio to receive surufatinib or placebo. HRQoL questionnaires, including the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-G.I.NET21, were collected. The prespecified HRQoL outcome was the mean change of scores from baseline to the last available visit for each domain. Time until definitive deterioration (TUDD) was defined as the time from randomization to deterioration of ≥10 points from baseline in domain score, disease progression, or death.

RESULTS

370 patients were enrolled and randomly assigned to surufatinib (n = 242) or placebo (n = 128). No significant difference in mean scores change from baseline to the last available visit was observed for QLQ-C30 and QLQ- G.I.NET21 domains, with the exception of diarrhea. The mean score of diarrhea increased 11.7 points from baseline in the surufatinib arm and decreased 1.2 points in the placebo arm, and the between-group difference was 12.9 points. Compared with placebo, surufatinib treated patients had a significantly longer TUDD for dyspnea (hazard ratio [HR] 0.58; 95% confidence interval [CI], 0.39-0.86; P = 0.0058) and a significantly shorter TUDD for diarrhea (HR 2.91; 95% CI, 1.66-5.10; P < 0.0001). There were no significant differences in TUDD for the remaining domains of QLQ-C30 and G.I.NET-21.

CONCLUSIONS

HRQoL was similar in patients treated with surufatinib and placebo except for diarrhea. The preservation of HRQoL supports surufatinib as a treatment option fo r NETs.

Anxiety, Depression and Quality of Life in Patients with Neuroendocrine Neoplasia After Surgery

BACKGROUND

Neuroendocrine neoplasia (NEN) are rare and complex, with surgery as key therapy even in cases with metastasis. Little is known regarding the quality of life, prevalence of depression, anxiety and the impact of surgery.

METHODS

This prospective, follow-up study included 90 consecutively recruited patients with NEN after surgery in a university hospital. The EORTC QLQ-C30, EORTC QLQ-GI-NET.21, and Hospital Anxiety and Depression Scale and a hospital specific questionnaire were completed during follow-up after 3 to 5 years (t1-t5).

RESULTS

Mean age was 54 (SD 15) years, 13% had secondary malignancies and 11% had psychiatric diagnoses (depression n = 8, schizophrenia n = 2) pre-existent. Critical life events occurred in 51% within 5 years before diagnosis. Surgery was done in curative intention in 82% and R0-resection rate was 90%. The median survival was 25.3 years. The 10-year survival rate was 87%, 98%, 95% and 26% for all patients (n = 90), stage I/II (n = 45), stage III (n = 25) and stage IV (n = 20), respectively (p < .001). Anxiety score was pathological in 30% after 1 year (t1) and in 10% after 5 years, depression score in 25% (t1) and 30% (t5). Fatigue and muscle/body pain were elevated symptoms with > 50 and 40 points 3 years after surgery.

CONCLUSION

Depression rate remains high whereas anxiety declines over time. Fatigue and muscle/body pain were identified as relevantly elevated after surgery. Systematic screening and supportive therapy should be implemented during follow-up after surgery.

Health-related quality of life and treatment effects in patients with well-differentiated gastroenteropancreatic neuroendocrine neoplasms: A systematic review and meta-analysis

Introduction

Gastroenteropancreatic neuroendocrine neoplasms (GEPNENs) are often diagnosed in an advanced stage. As the optimal sequence of therapy remains largely unclear, all treatment‐related outcomes, including health‐related quality of life (HRQoL) prospects, should be assessed according to patients' preferences.

Methods

A targeted search was performed in PubMed and EMBASE to identify studies on treatment effect and HRQoL, measured using the EORTC QLQ‐C30 tool, in patients with advanced, well‐differentiated GEPNENs. Study quality was assessed, and meta‐analyses were performed for global health status/QOL and tumour response.

Results

The search yielded 1,322 records, and 20 studies were included, examining somatostatin analogues (SSA), peptide receptor radionuclide therapies (PRRT), chemotherapy, SSA‐based combination therapies, and targeted therapies. Global HRQoL was stable, and rates for disease stabilisation were moderate to high across all treatments. Meta‐analyses for global health status/QOL after SSA treatment were not significant (mean difference: –0.3 [95% CI: −1.3 to 0.7]). The highest pooled overall tumour response rate was 33% (95% CI: 24–45%) for PRRT. The highest pooled clinical benefit rate was 94% (95% CI: 65–99%) for chemotherapy.

Conclusion

All treatments appeared beneficial for disease stabilisation while maintaining stable global health status/QOL. High‐quality HRQoL reporting was lacking. HRQoL should be a central outcome next to well‐established outcomes.

Physician-perceived utility of the EORTC QLQ-GINET21 questionnaire in the treatment of patients with gastrointestinal neuroendocrine tumours: a multicentre, cross-sectional survey (QUALINETS)

Background and objective

Patient-reported outcome measures can provide clinicians with valuable information to improve doctor-patient communication and inform clinical decision-making. The aim of this study was to evaluate the physician-perceived utility of the QLQ-GINET21 in routine clinical practice in patients with gastrointestinal neuroendocrine tumours (GI-NETs). Secondary aims were to explore the patient, clinician, and/or centre-related variables potentially associated with perceived clinical utility.

Methods

Non-interventional, cross-sectional, multicentre study conducted at 34 hospitals in Spain and Portugal (NCT02853422). Patients diagnosed with GI-NETs completed two health-related quality of life (HRQoL) questionnaires (QLQ-C30, QLQ-GINET21) during a single routine visit. Physicians completed a 14-item ad hoc survey to rate the clinical utility of QLQ-GINET21 on three dimensions: 1)therapeutic and clinical decision-making, 2)doctor-patient communication, 3)questionnaire characteristics.

Results

A total of 199 patients at 34 centres were enrolled by 36 participating clinicians. The highest rated dimension on the QLQ-GINET21 was questionnaire characteristics (86.9% of responses indicating “high utility”), followed by doctor-patient communication (74.4%), and therapeutic and clinical decision-making (65.8%). One physician-related variable (GI-NET patient volume > 30 patients/year) was associated with high clinical utility and two variables (older age/less experience treating GI-NETs) with low clinical utility.

Conclusions

Clinician-perceived clinical utility of QLQ-GINET21 is high. Clinicians valued the instruments’ capacity to provide a better understanding of patient perspectives and to identify the factors that had the largest influence on patient HRQoL.
