Systematic review on the impact of pancreatoduodenectomy on quality of life in patients with pancreatic cancer

Laparoscopic Versus Open Pancreatoduodenectomy for Periampullary Tumors: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

PURPOSE

Laparoscopic pancreatoduodenectomy (LPD) has emerged as an alternative to open technique in treating periampullary tumors. However, the safety and efficacy of LPD compared to open pancreatoduodenectomy (OPD) remain unclear. Thus, we conducted an updated meta-analysis to evaluate the efficacy and safety of LPD versus OPD in patients with periampullary tumors, with a particular focus on the pancreatic ductal adenocarcinoma patient subgroup.

METHODS

According to PRISMA guidelines, we searched PubMed, Embase, and Cochrane Library in December 2023 for randomized controlled trials (RCTs) that directly compare LPD versus OPD in patients with periampullary tumors. Endpoints and sensitive analysis were conducted for short-term endpoints. All statistical analysis was performed using R software version 4.3.1 with a random-effects model.

RESULTS

Five RCTs yielding 1018 patients with periampullary tumors were included, of whom 511 (50.2%) were randomized to the LPD group. Total follow-up time was 90 days. LPD was associated with a longer operation time (MD 66.75; 95% CI 26.59 to 106.92; p = 0.001; I2 = 87%; Fig. 1A), lower intraoperative blood loss (MD - 124.05; 95% CI - 178.56 to - 69.53; p < 0.001; I2 = 86%; Fig. 1B), and shorter length of stay (MD - 1.37; 95% IC - 2.31 to - 0.43; p = 0.004; I2 = 14%; Fig. 1C) as compared with OPD. In terms of 90-day mortality rates and number of lymph nodes yield, no significant differences were found between both groups.

CONCLUSION

Our meta-analysis of RCTs suggests that LPD is an effective and safe alternative for patients with periampullary tumors, with lower intraoperative blood loss and shorter length of stay.

The influence of delayed gastric emptying on quality of life after partial duodenopancreatectomy

PURPOSE

Quality of life (QoL) is temporarily compromised after pancreatic surgery, but no evidence for a negative impact of postoperative complications on QoL has been provided thus far. Delayed gastric emptying (DGE) is one of the most common complications after pancreatic surgery and is associated with a high level of distress. Therefore, the aim of this study was to analyse the influence of DGE on QoL.

METHODS

This single-centre retrospective study analysed QoL after partial duodenopancreatectomy (PD) via the European Organization for Research and Treatment of Cancer core questionnaire (QLQ-C30). The QoL of patients with and without postoperative DGE was compared.

RESULTS

Between 2010 and 2022, 251 patients were included, 85 of whom developed DGE (34%). Within the first postoperative year, compared to patients without DGE, those with DGE had a significantly reduced QoL, by 9.0 points (95% CI: -13.0 to -5.1, p < 0.001). Specifically, physical and psychosocial functioning (p = 0.020) decreased significantly, and patients with DGE suffered significantly more from fatigue (p = 0.010) and appetite loss (p = 0.017) than patients without DGE. After the first postoperative year, there were no significant differences in QoL or symptom scores between patients with DGE and those without DGE.

CONCLUSION

Patients who developed DGE reported a significantly reduced QoL and reduced physical and psychosocial functioning within the first year after partial pancreatoduodenectomy compared to patients without DGE.

Optimal age to discontinue long-term surveillance of intraductal papillary mucinous neoplasms: comparative cost-effectiveness of surveillance by age

OBJECTIVE

Current guidelines recommend long-term image-based surveillance for patients with low-risk intraductal papillary mucinous neoplasms (IPMNs). This simulation study aimed to examine the comparative cost-effectiveness of continued versus discontinued surveillance at different ages and define the optimal age to stop surveillance.

DESIGN

We constructed a Markov model with a lifetime horizon to simulate the clinical course of patients with IPMNs receiving imaging-based surveillance. We calculated incremental cost-effectiveness ratios (ICERs) for continued versus discontinued surveillance at different ages to stop surveillance, stratified by sex and IPMN types (branch-duct vs mixed-type). We determined the optimal age to stop surveillance as the lowest age at which the ICER exceeded the willingness-to-pay threshold of US$100 000 per quality-adjusted life year. To estimate model parameters, we used a clinical cohort of 3000 patients with IPMNs and a national database including 40 166 patients with pancreatic cancer receiving pancreatectomy as well as published data.

RESULTS

In male patients, the optimal age to stop surveillance was 76-78 years irrespective of the IPMN types, compared with 70, 73, 81, and 84 years for female patients with branch-duct IPMNs <20 mm, =20-29 mm, ≥30 mm and mixed-type IPMNs, respectively. The suggested ages became younger according to an increasing level of comorbidities. In cases with high comorbidity burden, the ICERs were above the willingness-to-pay threshold irrespective of sex and the size of branch-duct IPMNs.

CONCLUSIONS

The cost-effectiveness of long-term IPMN surveillance depended on sex, IPMN types, and comorbidity levels, suggesting the potential to personalise patient management from the health economic perspective.

Assessing the long-term priorities of pancreaticoduodenectomy survivors

BACKGROUND

This study assessed the long-term quality of life (QOL) and priorities of pancreaticoduodenectomy (PD) survivors.

METHODS

Survivors were surveyed via internet-based support groups. The relative importance of longevity, experience, costs, and QOL were assessed.

RESULTS

The PD cohort (n = 247, 35%) was 60 ± 12 years, 71% female, and 93% white. With moderate agreement, patients ranked survival most important, followed by functional and emotional well-being; costs and experience were least important (W = 35.7%, p < 0.001). Well-being improved throughout survivorship (P-QOL: 39 ± 12 at ≤3 mo vs 43 ± 12 at >10 y, p = 0.170; M-QOL: 38 ± 13 at ≤3 mo vs 44 ± 16 at >10 y; p = 0.015) but remained below the general population (p < 0.001). PD patients with benign diagnoses ranked functional independence as most important (2.00 ± 1.13 vs 2.63 ± 1.19, p < 0.001, W = 41.1%); PD patients with malignant diagnoses regarded overall survival most important (2.10 ± 1.20 vs 1.82 ± 1.22, p < 0.16, W = 35.1%). The mean rank order of priorities remained concordant between short-term (<1 year) and long-term (>5 years) survivors.

CONCLUSION

PD survivors experience long-term mental and physical health impairments, underscoring the importance of functional and emotional support. Survivors place paramount importance on overall survival, functional independence, and emotional well-being. Cancer survivors prioritize longevity, while survivors of chronic benign conditions prioritize functional independence.

Quality of life after pancreatoduodenectomy: Is the outcome predetermined by the diagnosis?

BACKGROUND AND OBJECTIVES

Non-physiological factors tied to the disease process may drive the diminished quality of life (QoL) after pancreatoduodenectomy (PD). We compared postoperative QoL among patients undergoing PD for either benign or malignant pathology.

METHODS

From 2012 to 2021, 228 patients underwent PD in a large healthcare system. Eighty-two patients (36.0%) were interviewed using the EORTC QLQ-C30 questionnaire. A minimum of 6 months after surgery was required for the survey. QoL outcomes were compared based on diagnosis (benign vs. malignant).

RESULTS

Patient mean age was 65 years (21-82), and forty-seven (57%) were men. Most patients underwent surgery for cancer, 76% (n = 62). Grade B postoperative pancreatic fistula incidence was higher in benign cases (30% vs. 6.5%, p = 0.024). Weight loss was more common in malignancy (79% vs. 50%, p = 0.016). Carcinoma patients felt less useful, hopeful, reported less control of their life and certainty of the future, and were less satisfied with their appearance. Carcinoma patients also reported diminished memory, fear of relapse, and greater financial burden.

CONCLUSIONS

Long-term QoL is inferior in PD patients with carcinoma and is driven by the psychological and socioeconomic implications of malignancy. Supportive resources for pancreas cancer patients should be evaluated and optimized.

Role of preoperative malnutrition and symptom severity in anorexia-cachexia-related quality of life in patients with operable pancreatic cancer

PURPOSE

This study assessed the changes in malnutrition status, symptom severity, and anorexia-cachexia-related quality of life (QoL) before and after pancreatic surgery and identified significant factors associated with changes in anorexia-cachexia-related QoL in patients with operable pancreatic cancer.

METHODS

In total, 76 patients with pancreatic cancer who were scheduled to undergo surgery were recruited from a medical center in northern Taiwan. The Mini Nutritional Assessment, Symptom Severity Scale, and Functional Assessment of Anorexia-Cachexia Therapy scale were used to assess the patients' nutritional status, symptom severity, and anorexia-cachexia-related QoL, respectively. Bioelectrical impedance analysis was performed using X-Scan Plus II to assess body composition. A generalized estimating equation approach was used to identify significant factors associated with anorexia-cachexia-related QoL.

RESULTS

In total, 42.1% of the patients had malnutrition or were at risk of malnutrition before surgery. Preoperative malnutrition (β = -3.857, p = .001) and higher early satiety (β = -0.629, p = .005), insomnia (β = -0.452, p = .025), and pain (β = -0.779, p < .001) were associated with lower anorexia-cachexia-related QoL.

CONCLUSION

Clinicians should actively assess the nutritional status of patients with pancreatic cancer before surgery and provide symptom cluster management interventions to improve nutrition, insomnia, and pain, which is crucial for enhancing patients' anorexia-cachexia-related QoL.

Serious complications of pancreatoduodenectomy correlate with lower rates of adjuvant chemotherapy: Results from the recurrence after Whipple's (RAW) study

INTRODUCTION

Adjuvant chemotherapy (AC) can prolong overall survival (OS) after pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). However, fitness for AC may be influenced by postoperative recovery. We aimed to investigate if serious (Clavien-Dindo grade ≥ IIIa) postoperative complications affected AC rates, disease recurrence and OS.

MATERIALS AND METHODS

Data were extracted from the Recurrence After Whipple's (RAW) study (n = 1484), a retrospective study of PD outcomes (29 centres from eight countries). Patients who died within 90-days of PD were excluded. The Kaplan-Meier method was used to compare OS in those receiving or not receiving AC, and those with and without serious postoperative complications. The groups were then compared using univariable and multivariable tests.

RESULTS

Patients who commenced AC (vs no AC) had improved OS (median difference: (MD): 201 days), as did those who completed their planned course of AC (MD: 291 days, p < 0.0001). Those who commenced AC were younger (mean difference: 2.7 years, p = 0.0002), more often (preoperative) American Society of Anesthesiologists (ASA) grade I-II (74% vs 63%, p = 0.004) and had less often experienced a serious postoperative complication (10% vs 18%, p = 0.002). Patients who developed a serious postoperative complication were less often ASA grade I-II (52% vs 73%, p = 0.0004) and less often commenced AC (58% vs 74%, p = 0.002).

CONCLUSION

In our multicentre study of PD outcomes, PDAC patients who received AC had improved OS, and those who experienced a serious postoperative complication commenced AC less frequently. Selected high-risk patients may benefit from targeted preoperative optimisation and/or neoadjuvant chemotherapy.

Minimally invasive versus open pancreatoduodenectomy for pancreatic ductal adenocarcinoma: Individual patient data meta-analysis of randomized trials

OBJECTIVE

Assessment of minimally invasive pancreatoduodenectomy (MIPD) in patients with pancreatic ductal adenocarcinoma (PDAC) is scarce and limited to non-randomized studies. This study aimed to compare oncological and surgical outcomes after MIPD compared to open pancreatoduodenectomy (OPD) for patients after resectable PDAC from published randomized controlled trials (RCTs).

METHODS

A systematic review was performed to identify RCTs comparing MIPD and OPD including PDAC (Jan 2015-July 2021). Individual data of patients with PDAC were requested. Primary outcomes were R0 rate and lymph node yield. Secondary outcomes were blood-loss, operation time, major complications, hospital stay and 90-day mortality.

RESULTS

Overall, 4 RCTs (all addressed laparoscopic MIPD) with 275 patients with PDAC were included. In total, 128 patients underwent laparoscopic MIPD and 147 patients underwent OPD. The R0 rate (risk difference(RD) -1%, P = 0.740) and lymph node yield (mean difference(MD) +1.55, P = 0.305) were comparable between laparoscopic MIPD and OPD. Laparoscopic MIPD was associated with less perioperative blood-loss (MD -91ml, P = 0.026), shorter length of hospital stay (MD -3.8 days, P = 0.044), while operation time was longer (MD +98.5 min, P = 0.003). Major complications (RD -11%, P = 0.302) and 90-day mortality (RD -2%, P = 0.328) were comparable between laparoscopic MIPD and OPD.

CONCLUSIONS

This individual patient data meta-analysis of MIPD versus OPD in patients with resectable PDAC suggests that laparoscopic MIPD is non-inferior regarding radicality, lymph node yield, major complications and 90-day mortality and is associated with less blood loss, shorter hospital stay, and longer operation time. The impact on long-term survival and recurrence should be studied in RCTs including robotic MIPD.

Innovation in the Surgical Management of Pancreatic Cystic Neoplasms: Same Operations, Narrower Indications, and an Individualized Approach to Decision-Making

Historically, the management of pancreatic cystic neoplasms (PCN) has been operative. Early intervention for premalignant lesions, including intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN), offers an opportunity to prevent pancreatic cancer-with potential decrement to patients' short-term and long-term health. The operations performed have remained fundamentally the same, with most patients undergoing pancreatoduodenectomy or distal pancreatectomy using oncologic principles. The role of parenchymal-sparing resection and total pancreatectomy remains controversial. We review innovations in the surgical management of PCN, focusing on the evolution of evidence-based guidelines, short-term and long-term outcomes, and individualized risk-benefit assessment.

Promoter hypermethylation of SFRP1 as a prognostic and potentially predictive blood-based biomarker in patients with localized pancreatic ductal adenocarcinoma

Introduction

Current prognostic blood-based biomarkers for pancreatic adenocarcinoma (PDAC) are limited. Recently, promoter hypermethylation of SFRP1 (phSFRP1) has been linked to poor prognosis in patients with gemcitabine-treated stage IV PDAC. This study explores the effects of phSFRP1 in patients with lower stage PDAC.

Methods

Based on a bisulfite treatment process, the promoter region of the SFRP1 gene was analyzed with methylation-specific PCR. Kaplan-Meier curves, log-rank tests, and generalized linear regression analysis were used to assess restricted mean survival time survival at 12 and 24 months.

Results

The study included 211 patients with stage I-II PDAC. The median overall survival of patients with phSFRP1 was 13.1 months, compared to 19.6 months in patients with unmethylated SFRP1 (umSFRP1). In adjusted analysis, phSFRP1 was associated with a loss of 1.15 months (95%CI -2.11, -0.20) and 2.71 months (95%CI -2.71, -0.45) of life at 12 and 24 months, respectively. There was no significant effect of phSFRP1 on disease-free or progression-free survival. In stage I-II PDAC, patients with phSFRP1 have worse prognoses than patients with umSFRP1.

Discussion

Results could indicate that the poor prognosis may be caused by reduced benefit from adjuvant chemotherapy. SFRP1 may help guide the clinician and be a possible target for epigenetically modifying drugs.

Pancreatic Dysfunction and Reduction in Quality of Life Is Common After Pancreaticoduodenectomy

BACKGROUND

Improvements in survival after pancreaticoduodenectomy has increased the number of patients potentially at risk of pancreatic insufficiency.

AIMS

We studied long-term (> 1 year) pancreatic functions (endocrine and exocrine) after pancreaticoduodenectomy and aimed to recognize the impact of various clinicopathological factors and postoperative complications on pancreatic functions.

METHODS

All patients who underwent pancreaticoduodenectomy at least 1 year prior were recruited from July 2020 to December 2021. Endocrine function was assessed using HbA1c, fasting blood sugar and postprandial blood sugar levels. Pancreatic exocrine function was assessed clinically with history of steatorrhea and objectively with quantitative estimation of fecal elastase-1 levels in stool samples. Volume of remnant pancreas, parenchymal thickness and duct diameter were assessed by computed tomography. Quality of life assessment was done using SF-36 questionnaire.

RESULTS

Of the 106 patients assessed, 64 patients met the inclusion criteria. Endocrine insufficiency was noted in 51.6%, and 34.3% had new onset diabetes mellitus. The incidence of pancreatic exocrine insufficiency was 87.5% and severe insufficiency was found in 62.5% of patients. Twenty-nine (45.3%) patients had both exocrine and endocrine insufficiency. Patients with CRPOPF had higher risk of severe exocrine insufficiency (5 vs. 2, OR 1.57(0.28-8.81) p = 0.6). The SF-36 scores were lower than general population especially in role limitation due to physical health, role limitation due to emotional problems, energy/fatigue, general health perception and health change domains.

CONCLUSION

Post-pancreaticoduodenectomy patients have a high frequency of pancreatic insufficiency and should be screened for same. The post-operative pancreatic fistula increases the risk of pancreatic exocrine insufficiency.

Pancreatoduodenectomy for suspected malignancy: nonmalignant histology confers increased risk of serious morbidity

BACKGROUND/AIMS

A tissue diagnosis is not always obtained prior to pancreatoduodenectomy (PD) and a proportion of patients are found to have noncancerous histology postoperatively. It is unknown if these patients have different outcomes when compared with those who have malignancy confirmed.

METHODS

A retrospective paired case matched control study was undertaken. Patients who underwent PD for suspected malignancy but ultimately had nonmalignant histology were identified. Each was matched to a confirmed malignant control using the following criteria: age, gender, body mass index, American Society of Anesthesiologists grade, neoadjuvant treatment, preoperative serum bilirubin, preoperative biliary stenting and type of pancreatic anastomosis. Matching was blinded to the measured outcomes, which included perioperative morbidity and mortality.

RESULTS

Forty-five cases were compared with 45 well-matched controls. There was no difference in 30- or 90-day mortality, or length of stay. While overall morbidity rates were the same, patients with nonmalignant disease were more likely to experience major (Clavien-Dindo grade III-IV) morbidity (40.0% versus 17.8%, p = 0.0352). Independently, rates of clinically relevant pancreatic fistula (CR-POPF) were higher in the nonmalignant group (22.2% versus 4.44%, p = 0.0131).

CONCLUSIONS

In our study, PD patients with nonmalignant histology had significantly higher incidence of major morbidity and CR-POPF when compared with those who had malignancy confirmed. This should be considered when planning the management of patients with known or presumed benign/premalignant disease.

High-risk liver patients are not associated with adverse events following pancreaticoduodenectomy

INTRODUCTION

Pancreaticoduodenectomy performed with underlying hepatic disease has been reported to have increased adverse events postoperatively. This study aimed to further evaluate that association.

METHODS

Retrospective review of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) main and targeted pancreatectomy registries for 2014-2016. High-risk liver patients were defined by MELD scores, received neoadjuvant chemotherapy, and had hepatosteatosis; two separate subgroups of MELD ≥9 and ≥ 11. High-risk liver patients were then compared to control cases via propensity score matching.

RESULTS

There were 156 and 132 cases that met the high-risk liver criteria for the MELD cutoffs of ≥9 and ≥ 11 respectively. Propensity score matching left 2527 cases for final adjusted analysis. On both univariate and multivariate analysis high-risk liver patients were not associated with increased adverse events following Whipple resection. Lack of association with increased adverse events held for both the ≥9 and ≥ 11 MELD score cohorts.

CONCLUSION

High-risk liver patients defined by MELD scores, neoadjuvant chemotherapy utilization, and hepatosteatosis were not associated with any increased incidence of adverse events following pancreaticoduodenectomy. Patients with underlying high-risk liver disease in this study did not appear to pose as a contraindication for oncologic resection of pancreatic adenocarcinoma.

Quality of Life in Patients with Pancreatic Cancer-A Literature Review

Pancreatic cancer is the malignant disease with the highest mortality rate, and it ranks third in the world after lung and colon cancer. Identified factors that increase the risk of developing pancreatic cancer include chronic pancreatitis, radiation therapy to the pancreatic area due to another cancer, diabetes mellitus, obesity, smoking, and age. The objective of this study was to present the current state of knowledge on the quality of life of patients diagnosed with pancreatic cancer, factors that determine QoL, and ways of coping with the disease. The low curability and low survival rates of pancreatic cancer significantly affect the quality of life of patients, often in the form of significant deterioration, especially in terms of mental changes, cognitive functions, and coping with the disease. Cognitive decline with comorbid depression is also typical for patients with this type of cancer. Research has shown that the health-related quality of life of patients with pancreatic cancer is low, so further research is needed to improve the situation in this area.

Pancreatic Enucleation Patients Share the Same Quality of Life as the General Population at Long-Term Follow-Up: A Propensity Score-Matched Analysis

OBJECTIVE

The aim of this study was to assess short- and long-term outcomes including quality of life (QoL) following pancreatic enucleation (PE).

BACKGROUND

PE is deemed to preserve both the endocrine and the exocrine function while ensuring radicality. However, to assess whether this reflects an actual benefit perceived by patients, QoL has to be considered.

METHODS

Data from all consecutive patients undergoing PE from January 2010 to December 2019 were retrospectively analyzed. Surgical outcomes were graded according to the Clavien-Dindo classification, and EORTC-C30 and the EORTC-Pan26 were administered as a cross-sectional assessment of QoL. A control group consisting of healthy individuals from the general population was obtained and matched using the propensity score matching method.

RESULTS

Eighty-one patients underwent PE using the open (59.3%), laparoscopic (27.2%), or robot-assisted (13.5%) approach. Sixty-five (80.2%) patients exhibited functioning/nonfunctioning pancreatic neuroendocrine tumors at final pathology.Surgical morbidity and complications of a Clavien-Dindo grade ≥3 were 48.1% and 16.0%, respectively. In-hospital mortality was 0%. Postoperative pancreatic fistula, post-pancreatectomy hemorrhage, and delayed gastric emptying rates were 21.0%, 9.9%, and 4.9%, respectively.Patients returned the questionnaires after a median of 74.2 months from the index surgery. Postoperative new onset of diabetes mellitus (NODM) was observed in 5 subjects (7.1%), with age being an independent predictor. Seven patients (10.0%) developed postoperative exocrine insufficiency. At the analysis of QoL, all function and symptom scales were comparable between the 2 groups, except for 2 of the EORTC-Pan 26 symptom scales, ("worries for the future" and "body image", P < 0.05).

CONCLUSIONS

Despite being associated with significant postoperative morbidity, PE provides excellent long-term outcomes. The risk of NODM is low and related to patient age, with QoL being comparable to the general population. Such information should drive surgeons to pursue PE whenever properly indicated.

Impact of endoscopic ultrasound-guided radiofrequency ablation in managing pancreatic malignancy

Pancreatic malignancy is still the most lethal gastrointestinal malignancy. It has a very poor prognosis with low survival rate. Surgery is still the main treatment option for pancreatic malignancy. Most patients already have locally advanced and even late stage disease due to non-specific abdominal symptoms. Even though some cases are still suitable for surgical treatment, due to its aggressiveness adjuvant chemotherapy is becoming the standard treatment for controlling the disease. Radiofrequency ablation (RFA) is a thermal therapy that has been used as one of the standard treatments for liver malignancy. It can also be performed intraoperatively. There are several reports on percutaneous RFA treatment for pancreatic malignancy using transabdominal ultrasound and guided by computed tomography scan. However, due to its anatomical location and the risk of high radiation exposure, these methods seem to be very limited. Endoscopic ultrasound (EUS) has been widely used for pancreatic abnormality evaluation due to its ability to detect more accurately, especially small pancreatic lesions, compared to other imaging modalities. By the EUS approach, it is easier to achieve good visualization of tumor ablation and necrosis as the echoendoscope position is closer to the tumor area. Based on studies and a recent meta-analysis, EUS-guided RFA is a promising treatment approach for most pancreatic malignancy cases, but most studies only collected data from a small sample size. Larger studies are needed before clinical recommendations can be made.

Experience of living with symptom clusters in postoperative pancreatic cancer patients

OBJECTIVE

The purpose of this study was to describe symptom clusters (SCs), and symptom experiences in early postoperative patients with pancreatic cancer who are recovering at home.

METHODS

From October 2021 and April 2022,15 patients following pancreatic cancer surgery were recruited from a tertiary hospital in Jiangsu Province by maximum variation sampling. Semi-structured interviews were performed to collect data and thematic analysis was conducted to analyze the data.

RESULTS

Three themes were extracted from the data. The first theme "difference in symptom perception and cognition" illustrated factors such as patient knowledge, expected recovery status, and risk perception could influence patient symptom experience. Most patients actually reported fewer and less severe symptoms than previous studies. The second theme "the results of symptom cluster" demonstrated anorexia-distress SC, bowel-digestive related SC and sleep disturbance related SC, and anorexia-distress SC should be considered as the priority SC given its multidimensional significance for patients. The last theme described the patient's positive attitudes, behaviours and barriers to coping with symptoms, namely "symptom self-management experience".

CONCLUSION

There are differences in the perception and interpretation of SCs in postoperative pancreatic cancer patients. Understanding the meaning of individual differences in the experience of symptoms can assist patients in the management of SCs. Medical staff should combine patient self-management strategies and evidence-based data to provide appropriate support at different stages to improve patient symptom management and quality of life.

Immune response and drug therapy based on ac4C-modified gene in pancreatic cancer typing

N-4 cytidine acetylation (ac4C) is an epitranscriptome modification catalyzed by N-acetyltransferase 10 (NAT10) and is essential for cellular mRNA stability, rRNA biosynthesis, cell proliferation, and epithelial-mesenchymal transition (EMT). Numerous studies have confirmed the inextricable link between NAT10 and the clinical characteristics of malignancies. It is unclear, however, how NAT10 might affect pancreatic ductal adenocarcinoma. We downloaded pancreatic ductal adenocarcinoma patients from the TCGA database. We obtained the corresponding clinical data for data analysis, model construction, differential gene expression analysis, and the GEO database for external validation. We screened the published papers for NAT10-mediated ac4C modifications in 2156 genes. We confirmed that the expression levels and genomic mutation rates of NAT10 differed significantly between cancer and normal tissues. Additionally, we constructed a NAT10 prognostic model and examined immune infiltration and altered biological pathways across the models. The NAT10 isoforms identified in this study can effectively predict clinical outcomes in pancreatic ductal adenocarcinoma. Furthermore, our study showed that elevated levels of NAT10 expression correlated with gemcitabine resistance, that aberrant NAT10 expression may promote the angiogenic capacity of pancreatic ductal adenocarcinoma through activation of the TGF-β pathway, which in turn promotes distal metastasis of pancreatic ductal adenocarcinoma, and that NAT10 knockdown significantly inhibited the migration and clonogenic capacity of pancreatic ductal adenocarcinoma cells. In conclusion, we proposed a predictive model based on NAT10 expression levels, a non-invasive predictive approach for genomic profiling, which showed satisfactory and effective performance in predicting patients' survival outcomes and treatment response. Medicine and electronics will be combined in more interdisciplinary areas in the future.

Serious complications of pancreatoduodenectomy correlate with lower rates of adjuvant chemotherapy: Would high-risk patients benefit from neoadjuvant therapy?

INTRODUCTION

Patients who suffer a serious complication of pancreatoduodenectomy (PD) may have their adjuvant chemotherapy (AC) delayed or omitted as a result. We aimed to investigate whether PD complications affected AC rates.

MATERIALS AND METHODS

A retrospective analysis of all PD patients with histologically-confirmed pancreatic ductal adenocarcinoma (2006-2015) was performed; 90-day mortality patients were excluded. Patients who commenced AC were compared to those who did not (morbidity rates and survival) and patients who developed selected postoperative complications were compared to those who did not (AC rates and survival).

RESULTS

157 patients were included and 90-day mortality was 3.8%. Of the remaining patients, 102 (68.5%) received AC (AC data unavailable for two patients). Survival was longer in the AC group (p = 0.004). AC patients had less frequently experienced a postoperative chest infection (8.82% vs 34.0%, p = 0.0003) or a postoperative complication which was Clavien-Dindo (CD) grade ≥ II (29.4% vs 57.4%, p = 0.0019) or ≥ III (6.86% vs 21.3%, p = 0.023). Patients who experienced a postoperative chest infection (36.0% vs 75.0%, p = 0.0003) or a postoperative complication which was CD grade ≥ II (48.9% vs 73.1%, p = 0.0099) or ≥ III (29.4% vs 70.3%, p = 0.0018) less frequently commenced AC.

CONCLUSION

Patients who received AC had less frequently experienced a serious postoperative complication. Efforts should be made to preoperatively identify those who are high-risk for a serious complication as this cohort may benefit from neoadjuvant therapy.

Complications and chemotherapy have little impact on postoperative quality of life after pancreaticoduodenectomy - a cohort study

BACKGROUND

With the poor prognosis of pancreatic cancer and the high rate of postoperative complications after pancreaticoduodenectomy, it is important to evaluate how the operation affects patients' quality of life.

METHODS

This single-centre study included all patients undergoing pancreaticoduodenectomy from 2006 to 2016. Quality of life was measured with two questionnaires preoperatively, and at 6 and 12 months postoperatively. Comparisons between groups were made using a linear mixed models analysis.

RESULTS

Of 279 patients planned for pancreaticoduodenectomy, 245 underwent the operation. The postoperative response rates were all 80% or more. Differences were found in one domain between the early and late time periods and three domains between patients receiving and not receiving adjuvant chemotherapy. No significant differences were found between patients with and without severe postoperative complications. However, the demographic variables of age group, sex, preoperative diabetes and smoking all exerted a significant impact on postoperative quality of life.

CONCLUSION

While little or no impact was shown for the factors of postoperative complications, time period and adjuvant chemotherapy, demographic data, such as age, sex, preoperative diabetes and smoking, had considerable impacts on postoperative quality of life after pancreaticoduodenectomy.

Quality of life after pancreatic surgery - A systematic review

BACKGROUND

Surgery for patients with pancreatic cancer carries a high risk of major post-operative complications and only marginally improves overall survival. This review aims to assess the impact of surgical resection on health-related quality of life (HRQOL) of pancreatic cancer patients.

METHODS

A systematic review of the literature was performed according to the PRISMA guidelines. All studies assessing QOL using validated questionnaires in pancreatic cancer patients undergoing surgical resection were included.

RESULTS

Twenty-two studies were assessed. Patients reported a decrease in physical, social and global scales within the first 3 months after surgery. These values showed improvement and were comparable to baseline values by 6 months. Recovery in emotional functioning towards baseline figures was demonstrated in the first 3 months post-operatively. Symptom scales including pain, fatigue and diarrhoea deteriorated after surgery, but reverted to baseline after 3-6 months.

CONCLUSIONS

Surgical resection for pancreatic cancer has short-term negative impact on QOL. In the longer term, this will improve and eventually recover to baseline values after 6 months. Knowledge on the impact of surgery on QOL of pancreatic cancer patients is necessary to facilitate decision-making and tailoring of surgical techniques to the individual patient.

Are older patients less likely to be treated for pancreatic cancer? A systematic review and meta-analysis

Pancreatic cancer is the seventh commonest cause of cancer-related death worldwide. Although prognosis is poor, both surgery and adjuvant chemotherapy improve survival. However, it has been suggested that not all pancreatic cancer patients who may benefit from treatment receive it. This systematic review and meta-analysis investigated the existence of age-related inequalities in receipt of first-line pancreatic cancer treatment. Medline, Embase, Cochrane Library and grey literature were searched for population-based studies investigating treatment receipt, reported by age, for patients with primary pancreatic cancer from inception until 4th June 2020, and updated 5th August 2021. Studies from countries with universal healthcare were included, to minimise influence of health system-related economic factors. A modified version of the Newcastle-Ottawa Scale was used to assess risk of bias. Random-effects meta-analysis was undertaken comparing likelihood of treatment receipt in older versus younger patients. Sensitivity and subgroup analyses were conducted. Eighteen papers were included; 12 independent populations were eligible for meta-analysis. In most studies, < 10% of older patients were treated. Older age (generally ≥65) was significantly associated with reduced receipt of any treatment (OR=0.14, 95% CI 0.10-0.21, n = 12 studies), surgery (OR=0.15, 95% CI 0.09-0.24, n = 9 studies) and chemotherapy as a primary treatment (OR=0.13, 95% CI 0.07-0.24, n = 5 studies). The effect of age was independent of methodological quality, patient population or time-period of patient diagnosis and remained in studies with confounder adjustment. The mean quality score of included studies was 6/8. Inequalities in receipt of healthcare interventions across social groups is a recognised concern internationally. This review shows that older age is significantly, and consistently, associated with non-receipt of treatment in pancreatic cancer. However, there are risks and side-effects associated with pancreatic cancer treatment. Further research on what influences patient and professional treatment decision-making is required to better understand these apparent inequalities.

Effects of intensive physiotherapy on Quality of Life (QoL) after pancreatic cancer resection: a randomized controlled trial

BACKGROUND

Patients have significantly lower QoL scores after pancreatic resection due to cancer in the physical and psychological domains compared to healthy controls or other cancer patients. Intensified physiotherapy or physical training can increase QoL by reducing fatigue levels and improving physical functioning. However, data on the long-term effects of intensive or supervised physiotherapy is lacking. The aim of this exploratory study is the assessment of QoL in the intervention group, using various QoL questionnaires in their validated German translations and gather data on its feasibility in the context of chemotherapy with a follow-up of 12 months (and develop concepts to improve QoL after pancreatic cancer resection).

METHODS

Fifty-six patients (mean age: 66.4 ± 9.9 years) were randomized in this study to intervention (cohort A, n = 28) or control group (cohort B, n = 28). Intervention of intensified physiotherapy program consisted of endurance and muscle force exercises using cycle ergometer. In the control group physiotherapy was limited to the duration of the hospital stay and was scheduled for 20 min on 5 days per week. The clinical visits took place 2 days preoperatively, 1 week, 3 months, 6 months and 12 months postoperatively. Both groups attended the follow-up program. QoL was evaluated using the Short Physical Performance Battery (SPPB), Short Form-8 Health Survey (SF-8) and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and pancreatic cancer-specific module QLQ-PAN26 questionnaires. The course of QoL was evaluated using a repeated measures ANOVA and a per protocol design.

RESULTS

Of the initial 56 randomized patients, 34 finished the 12 months follow-up period. There were no adverse events due to the intervention and 80% of patients in the intervention group where adherent. There was no significant influence on physical performance as measured by SPPB and SF-8 questionnaire. However, after 6 months patients in the intervention group regained their prior physical condition, whereas the control group did not. Intensive physiotherapy significantly influenced various factors of QoL measured with the C30 questionnaire positively, such as physical functioning (p = 0.018), role functioning (p = 0.036), and appetite loss (p = 0.037), even after 6 months. No negative effects in patients undergoing chemotherapy compared to those without chemotherapy was observed.

CONCLUSION

This first randomized controlled study with a 12-month follow-up shows that supervised physiotherapy or prescribed home-based exercise after pancreatic cancer resection is safe and feasible and should be proposed and started as soon as possible to improve certain aspects of QoL.

The impact of cancer treatment on quality of life in patients with pancreatic and periampullary cancer: a propensity score matched analysis

BACKGROUND

The impact of pancreatic and periampullary cancer treatment on health-related quality of life (HRQoL) is unclear.

METHODS

This study merged data from the Netherlands Cancer Registry with EORTC QLQ-C30 and -PAN26 questionnaires at baseline and three-months follow-up of pancreatic and periampullary cancer patients (2015-2018). Propensity score matching (1:3) of group without to group with treatment was performed. Linear mixed model regression analyses were performed to investigate the association between cancer treatment and HRQoL at follow-up.

RESULTS

After matching, 247 of 629 available patients remained (68 (27.5%) no treatment, 179 (72.5%) treatment). Treatment consisted of resection (n = 68 (27.5%)), chemotherapy only (n = 111 (44.9%)), or both (n = 40 (16.2%)). At follow-up, cancer treatment was associated with better global health status (Beta-coefficient 4.8, 95% confidence-interval 0.0-9.5) and less constipation (Beta-coefficient -7.6, 95% confidence-interval -13.8-1.4) compared to no cancer treatment. Median overall survival was longer for the cancer treatment group compared to the no treatment group (15.4 vs. 6.2 months, p < 0.001).

CONCLUSION

Patients undergoing treatment for pancreatic and periampullary cancer reported slight improvement in global HRQoL and less constipation at three months-follow up compared to patients without cancer treatment, while overall survival was also improved.

Preoperative predictors for early and very early disease recurrence in patients undergoing resection of pancreatic ductal adenocarcinoma

BACKGROUND

This study aimed to identify predictors for early and very early disease recurrence in patients undergoing resection of pancreatic ductal adenocarcinoma (PDAC) resection with and without neoadjuvant therapy.

METHODS

Included were patients who underwent PDAC resection (2014-2016). Multivariable multinomial regression was performed to identify preoperative predictors for manifestation of recurrence within 3, 6 and 12 months after PDAC resection.

RESULTS

836 patients with a median follow-up of 37 (interquartile range [IQR] 30-48) months and overall survival of 18 (IQR 10-32) months were analyzed. 670 patients (80%) developed recurrence: 82 patients (10%) <3 months, 96 patients (11%) within 3-6 months and 226 patients (27%) within 6-12 months. LogCA 19-9 (OR 1.25 [95% CI 1.10-1.41]; P < 0.001) and neoadjuvant treatment (OR 0.09 [95% CI 0.01-0.68]; P = 0.02) were associated with recurrence <3 months. LogCA 19-9 (OR 1.23 [95% CI 1.10-1.38]; P < 0.001) and 0-90° venous involvement on CT imaging (OR 2.93 [95% CI 1.60-5.37]; P < 0.001) were associated with recurrence within 3-6 months. A Charlson Age Comorbidity Index ≥4 (OR 1.53 [95% CI 1.09-2.16]; P = 0.02) and logCA 19-9 (OR 1.24 [95% CI 1.14-1.35]; P < 0.001) were related to recurrence within 6-12 months.

CONCLUSION

This study demonstrates preoperative predictors that are associated with the manifestation of early and very early recurrence after PDAC resection. Knowledge of these predictors can be used to guide individualized surveillance and treatment strategies.

Oral adverse events due to zinc deficiency after pancreaticoduodenectomy requiring continuous intravenous zinc supplementation: a case report and literature review

Background

Zinc is mainly absorbed in the duodenum and proximal jejunum, which are removed during pancreaticoduodenectomy (PD). Little is known about the adverse oral events and skin disorders caused by zinc deficiency after PD. Herein, we reviewed studies on the development of zinc deficiency after PD and reported about a patient with zinc deficiency after PD who required home intravenous zinc replacement.

Case presentation

A 73-year-old woman with glossitis, taste disorder, and acrodermatitis enteropathica-like eruption on her fingers presented to the Division of Dentistry and Oral Surgery 69 days after PD. Her serum zinc level markedly decreased to 30 μg/dL. Oral zinc administration was inadequate to treat hypozincemia after PD; therefore, multi-trace elements were injected intravenously during readmission. Her serum zinc levels recovered, and her lesions gradually improved. Furthermore, a central venous port was implanted to maintain normal serum zinc levels, and she continued self-injecting zinc at home.

Conclusions

Zinc deficiency after PD rarely occurs. The clinical oncologist community, including dentists responsible for the oral care of cancer patients, should be aware of the oral adverse events, such as dysgeusia, glossitis, and oral pain, associated with zinc deficiency after cancer surgery and that induced by chemotherapy or head and neck radiation therapy.

Pilot trial of remote monitoring to prevent malnutrition after hepatopancreatobiliary surgery

Background

Patients undergoing hepatopancreatobiliary (HPB) surgery, such patients with pancreatic, periampullary, and liver cancer, are at high risk for malnutrition. Malnutrition increases surgical complications and reduces overall survival. Despite its severity, there are limited interventions addressing malnutrition after HPB surgery. The aim of this pilot trial was to examine feasibility, acceptability, usability, and preliminary efficacy of a remote nutrition monitoring intervention after HPB surgery.

Methods

Participants received tailored nutritional counseling before and after surgery at 2 and 4 weeks after hospital discharge. Participants also recorded nutritional intake daily for 30 days, and these data were reviewed remotely by registered dietitians before nutritional counseling visits. Descriptive statistics were used to describe study outcomes.

Results

All 26 patients approached to participate consented to the trial before HPB surgery. Seven were excluded after consent for failing to meet eligibility criteria (e.g., did not receive surgery). Nineteen participants (52.6% female, median age = 65 years) remained eligible for remote monitoring post-surgery. Nineteen used the mobile app food diary, 79% of participants recorded food intake for greater than 80% of study days, 95% met with the dietitian for all visits, and 89% were highly satisfied with the intervention. Among participants with complete data, the average percent caloric goal obtained was 82.4% (IQR: 21.7).

Conclusions

This intervention was feasible and acceptable to patients undergoing HPB surgery. Preliminary efficacy data showed most participants were able to meet calorie intake goals. Future studies should examine intervention efficacy in a larger, randomized controlled trial.

The patient's perspective: a qualitative study of individual experience with decision-making, treatment, and recovery for resectable pancreatic cancer

INTRODUCTION

Pancreatic ductal adenocarcinoma cancer (PDAC) remains a challenging diagnosis. The likelihood of long-term survival is limited even for patients who undergo maximal medical therapy with systemic chemotherapy and surgical resection. Within this intensive process, there remains limited understanding of patients' pretreatment expectations of PDAC treatment experience and their decision-making process.

METHODS

PDAC patients who underwent chemotherapy and surgical resection were retrospectively identified. Semi-structured phone interviews were completed regarding patient experience with therapy. Qualitative descriptive analysis was performed, and categories, subcategories, and themes were determined.

RESULTS

Fifteen patients were interviewed regarding their experience with PDAC treatment. An overall personal disease trajectory experience was identified with two phases. The first phase encompassed the patients' treatment. In this phase, patients expressed a choice, non-choice regarding therapy decisions, viewing therapy as the only option. Misconceptions about the roles of therapies and expected experience of treatment were observed. The second phase focused on life after therapy. Patients reported persistent physical changes secondary to therapy. An overall realistic understanding of the patient's limited prognosis was observed, with patients expressing appreciation of the life time gained as a benefit of treatment.

CONCLUSIONS

There remains critical areas for improvement in communication and care of patients with PDAC. Physicians should continue to ensure that patient's goals and wishes are respected when making treatment decisions and confirm that patients understand the roles and limitations of prescribed therapies. Additionally, patients continue to have significant physical changes post treatment which should be assessed for and managed as appropriate to maintain quality of life.

Pancreaticoduodenectomy: Impact of Volume on Outcomes at a Tertiary Care Center-Our Experience in Single Institute of Nepal

BACKGROUND

Pancreaticoduodenectomy is a complex high-risk surgical procedure usually done for malignant disease carrying significant postoperative morbidity and mortality. An audit and analysis of rate of postoperative morbidity and mortality and the impact of case volume can provide information about the lacunas in patient care and methods to improve it for safe and early discharge of patients. This study was conducted to find out demographic profile, the rate of perioperative morbidities, mortality, and impact of case volume on patients undergoing pancreaticoduodenectomy for malignant disease which may serve as a guide to uplift the patient care in our center.

METHODS

Retrospective analysis of prospectively collected data of patients undergoing pancreaticoduodenectomy from 2015 to 2019 was performed. A total of 62 patients were included in the study. Patient's clinic-demographic details and intraoperative and postoperative events were recorded. The rate of various postoperative morbidities and mortality and year-wise trend of these factors were analyzed.

RESULTS

Most of the patients were in the sixth decade of life (38.7%) with male preponderance (61.3%). Pancreatic cancer was most commonly seen followed by cholangiocarcinoma (46.8%). SSI (32.3%), intraabdominal collection (25.8%), anastomotic leak (14.5%), pancreatic fistula (22.6%), and postpancreatectomy hemorrhage (8.1%) were the major postoperative events. Mortality was found in 12.9% patients.

CONCLUSION

There has been a decrease in rate of all these postoperative adverse events and improvement in the intraoperative blood loss and surgical duration with advancing years and increasing number of cases.

Quality of Life Instruments and Trajectories After Pancreatic Cancer Resection: A Systematic Review

ABSTRACT

This systematic review aimed to investigate the instruments available to measure quality of life (QOL) after pancreatic cancer surgery and to describe short- and long-term QOL outcomes. A comprehensive literature search was completed using PubMed, Embase, and Medline from inception to March 2019. Studies investigating QOL outcomes in patients undergoing pancreatic cancer surgery who were 18 years or older were included. The main outcomes of interest were QOL instruments and short (≤6 months) and long term (>6 months) QOL outcomes. The overarching domains of physical, psychosocial, overall QOL, symptoms, and other were used to summarize QOL outcomes. Thirty-five studies reporting on 3573 patients were included. Fifteen unique QOL instruments were identified, of which 4 were disease-specific instruments. Most of the included studies reported no changes in QOL at short- and long-term follow-ups for the overarching domains. No difference in QOL outcomes was reported between different surgical approaches, except laparoscopic versus open distal pancreatectomy, and pancreaticoduodenectomy versus distal pancreatectomy. There are a wide range of instruments available to measure QOL outcomes in pancreatic cancer surgical patients, although only few are disease-specific. Most of the included studies reported no significant changes in QOL outcomes at short- or long-term follow-ups.

[Definition and treatment of superior mesenteric artery revascularization and dissection-associated diarrhea (SMARD syndrome) in Germany]

Hintergrund

Die A. mesenterica superior (AMS) wird im Rahmen von Pankreasresektionen (PR) und mesenterialen Gefäßeingriffen (MG) freigelegt und disseziert. Eine dadurch entstandene Schädigung des umliegenden ex- und intrinsischen vegetativen Nervenplexus kann zu einer passageren oder therapierefraktären Diarrhö führen.

Fragestellung

Die vorliegende Studie soll einen Überblick über den derzeitigen Stellenwert der AMS-Revaskularisations- und -Dissektions-assoziierten Diarrhö („superior mesenteric artery revascularisation and dissection-associated diarrhea“[SMARD]-Syndrom) in Deutschland geben.

Material und Methoden

Nach selektiver Literaturrecherche (SLR) mit der Fragestellung, ob und wie häufig eine postoperativ neu aufgetretene Diarrhö nach PR und MG vorkommt, wurde eine Onlineumfrage versendet.

Ergebnisse

Die SLR (n = 4) bestätigte, dass eine postoperativ neu aufgetretene Diarrhö eine häufige Komplikation nach Präparation zur Revaskularisation (RV) bzw. Dissektion (DIS) der AMS ist (Inzidenz ca. 62 %). Therapierefraktäre Verläufe sind selten 14 %. 54 von 159 Zentren beteiligten sich an der Umfrage. 63 % gaben an, eine AMS-RV/-DIS im Rahmen von PR oder MG durchzuführen. Der Durchschnitt an PR pro Zentrum lag 2018 bei 47 und bei 49 im Jahr 2019. Fünf MG erfolgten durchschnittlich in beiden Jahren pro Zentrum. Drei Patienten litten durchschnittlich am SMARD-Syndrom.

Diskussion

Diese Umfrage erfasst erstmals den derzeitigen Stellenwert des SMARD-Syndroms in Deutschland. Bisher fehlen Empfehlungen zur Therapie einer solchen Diarrhö. Die Ergebnisse zeigen, dass zunächst eine symptomatische Therapie erfolgen sollte. Aufgrund der Komplexität der Pathophysiologie sind kausale Therapieansätze bislang nicht entwickelt.

Curing pancreatic cancer

The distinct biology of pancreatic cancer with aggressive and early invasive tumor cells, a tumor promoting microenvironment, late diagnosis, and high therapy resistance poses major challenges on clinicians, researchers, and patients. In current clinical practice, a curative approach for pancreatic cancer can only be offered to a minority of patients and even for those patients, the long-term outcome is grim. This bitter combination will eventually let pancreatic cancer rise to the second leading cause of cancer-related mortalities. With surgery being the only curative option, complete tumor resection still remains the center of pancreatic cancer treatment. In recent years, new developments in neoadjuvant and adjuvant treatment have emerged. Together with improved perioperative care including complication management, an increasing number of patients have become eligible for tumor resection. Basic research aims to further increase these numbers by new methods of early detection, better tumor modelling and personalized treatment options. This review aims to summarize the current knowledge on clinical and biologic features, surgical and non-surgical treatment options, and the improved collaboration of clinicians and basic researchers in pancreatic cancer that will hopefully result in more successful ways of curing pancreatic cancer.

Achieving 'Marginal Gains' to Optimise Outcomes in Resectable Pancreatic Cancer

Simple Summary

Improving outcomes in pancreatic cancer is achievable through the accumulation of marginal gains. There exists evidence of variation and undertreatment in many areas of the care pathway. By fully realising the existing opportunities, there is the potential for immediate improvements in outcomes and quality of life.

Abstract

Improving outcomes among patients with resectable pancreatic cancer is one of the greatest challenges of modern medicine. Major improvements in survival will result from the development of novel therapies. However, optimising existing pathways, so that patients realise benefits of already proven treatments, presents a clear opportunity to improve outcomes in the short term. This narrative review will focus on treatments and interventions where there is a clear evidence base to improve outcomes in pancreatic cancer, and where there is also evidence of variation and under-treatment. Avoidance of preoperative biliary drainage, treatment of pancreatic exocrine insufficiency, prehabiliation and enhanced recovery after surgery, reducing perioperative complications, optimising opportunities for elderly patients to receive therapy, optimising adjuvant chemotherapy and regular surveillance after surgery are some of the strategies discussed. Each treatment or pathway change represents an opportunity for marginal gain. Accumulation of marginal gains can result in considerable benefit to patients. Given that these interventions already have evidence base, they can be realised quickly and economically.

[Results of pancreatic surgery from the perspective of patients: a cross-sectional study of the support group "Arbeitskreis der Pankreatektomierten e. V."]

BACKGROUND

 The support group "Arbeitskreis der Pankreatektomierten e. V. (AdP)" was founded in 1976 and is the largest group of individuals affected by pancreatic disease in Germany. Members of the AdP support patients with pancreatic disease. This patient-initiated, cross-sectional study intends to present the results of pancreatic surgery from the perspective of patients.

METHODS

 Since March the 3 rd, 2018, members of the AdP received a questionnaire with eleven categories of questions concerning their medical history. This data was gathered in a medical database and analysed.

RESULTS

 625 members were operated upon, with 57.5 % receiving pancreaticoduodenectomy, 15.5 % distal pancreatectomy, 23.2 % total pancreatectomy, and 4.0 % another or unknown operation. 37.9 % were diagnosed with pancreatic cancer, 38.2 % with another type of pancreatic tumour, 25 % with pancreatitis, 4 % with autoimmune pancreatitis and 2.7 % with other rare entities.82 patients of 237 pancreatic cancer patients survived more than 5 years. 24.5 % of the 237 patients reported have a second primary malignancy and 13.9 % have close family members with pancreatic cancer.Weight loss after pancreatic surgery was dependant on the type of operation with the greatest after pancreatectomy (17.8 ± 9.5 kg). The prevalence of diabetes was 54.1 %, the incidence of new onset perioperative diabetes 33.3 %. 91.5 % needed pancreatic enzyme replacement therapy, on average 189 417 IE/day. The reported quality of life was independent from type of surgery received.

CONCLUSION

 Following complex pancreatic surgery, patients are confronted with daily lifelong challenges. AdP members offering their shared experiences offer meaningful support to newly affected patients. Individuals affected by pancreatic disease could be an important but underutilised resource to studying these diseases.

Gastrointestinal side effects of upper gastrointestinal cancer surgery

In this chapter, we describe the gastrointestinal side effects of oesophagectomy, gastrectomy and pancreaticoduodenectomy for cancer, with a focus on long-term functional impairments and their management. Improvements in upper gastrointestinal cancer surgery have led to a growing group of long-term survivors. The invasive nature of these surgeries profoundly alters the upper gastrointestinal anatomy, with lasting implications for long-term function, and how these impairments may be treated. Successfully maintaining a high quality of survivorship requires multidisciplinary approach, with survivorship care plans focused on function as much as the detection of recurrence.

Patient experience and quality of life during neoadjuvant therapy for pancreatic cancer: a systematic review and study protocol

PURPOSE

Neoadjuvant therapy (NT) is increasingly being offered to patients with pancreatic ductal adenocarcinoma (PDAC) prior to surgical resection. However, the experience and quality of life (QOL) of patients undergoing NT are poorly understood.

METHODS

A systematic review of the Cinahl, Embase, Medline, Pubmed, Scopus, and Web of Science databases was conducted to evaluate the available literature pertaining to the experience and QOL of patient's undergoing NT for PDAC.

RESULTS

Among 6041 articles screened, only six met criteria for full-text review including three prospective clinical trials of NT with QOL secondary endpoints. Overall, global QOL during or following NT did not significantly change from baseline. Pain scores seemed to improve during NT while the impact of NT on physical functioning varied across studies. No studies were identified evaluating other aspects of the patient experience.

CONCLUSION

Although NT appears to have a minor impact on the QOL of patients with PDAC, this systematic review identified significant evidence gaps in the literature. A protocol of a prospective observational cohort study utilizing a digital smartphone app that aims to evaluate the patient experience and longitudinal QOL of patients with PDAC undergoing NT is presented.

Prehabilitation prior to surgery for pancreatic cancer: A systematic review

INTRODUCTION

Prehabilitation aims to improve fitness and outcomes of patients undergoing major surgery. This systematic review aimed to appraise current available evidence regarding the role of prehabilitation in patients undergoing oncological pancreatic resection.

METHODS

A systematic literature search of PUBMED, MEDLINE, EMBASE databases identified articles describing prehabilitation programmes before pancreatic resection for malignancy. Data collected included timing of prehabilitation, programme type, duration, adherence and post-operative outcome reporting.

RESULTS

Six studies, including 193 patients were included in the final analysis. Three studies included patients undergoing neoadjuvant therapy followed by resection and 3 studies included patients undergoing upfront resection. Time from diagnosis to surgery ranged between 2 and 22 weeks across all studies. Two studies reported a professionally supervised exercise programme, and four described unsupervised programmes. Exercise programmes varied from 5 days to 6 months in duration. Adherence to exercise programmes was better with supervised programmes (99% reaching weekly activity goal vs 85%) and patients not undergoing neoadjuvant therapy (90% reaching weekly activity goal vs 82%). All studies reported improvement in muscle mass or markers of muscle function following prehabilitation. Two studies reported the impact of Prehabilitation on postoperative outcomes and Prehabilitation was associated with lower delayed gastric emptying and a shorter hospital stay with no impact on other postoperative outcomes.

CONCLUSION

Early evidence demonstrates that Prehabilitation programmes may improve postoperative outcomes following pancreatic surgery. However current Prehabilitaton programmes for patients undergoing pancreatic resection report diverse exercise regimens with no consensus regarding timing or length of Prehabilitation, warranting a need for standardisation of Prehabilitation programmes in pancreatic surgery.

Pancreatic exocrine insufficiency after pancreaticoduodenectomy: Current evidence and management

Pancreaticoduodenectomy (PD) is the commonest procedure performed for pancreatic cancer. Pancreatic exocrine insufficiency (PEI) may be caused or exacerbated by surgery and remains underdiagnosed and undertreated. The aim of this review was to ascertain the incidence of PEI, its consequences and management in the setting of PD for indications other than chronic pancreatitis. A literature search of databases (MEDLINE, EMBASE, Cochrane and Scopus) was carried out with the MeSH terms “pancreatic exocrine insufficiency” and “Pancreaticoduodenectomy”. Studies that analysed PEI and its complications in the setting of PD for malignant and benign disease were included. Studies reporting PEI in the setting of PD for chronic pancreatitis, conference abstracts and reviews were excluded. The incidence of PEI approached 100% following PD in some series. The pre-operative incidence varied depending on the characteristics of the patient cohort and it was higher (46%-93%) in series where pancreatic cancer was the predominant indication for surgery. Variability was also recorded with regards to the method used for the diagnosis and evaluation of pancreatic function and malabsorption. Pancreatic enzyme replacement therapy is the mainstay of the management. PEI is common and remains undertreated after PD. Future studies are required for the identification of a well-tolerated, reliable and reproducible diagnostic test in this setting.

Understanding pancreatic exocrine insufficiency and replacement therapy in pancreatic cancer

Pancreatic exocrine insufficiency (PEI) is highly prevalent in patients with pancreatic cancer, and has substantial implications for quality of life and survival. Post resection, PEI is associated with increased post-operative complications, longer hospital stays and higher costs. Treatment with pancreatic enzyme replacement therapy (PERT) improves quality of life and confers significant survival advantages. Despite this many patients with pancreatic cancer do not currently receive PERT. The nutritional consequences of PEI are extensive and even more relevant in the elderly owing to age related gastrointestinal tract and pancreatic changes that predispose to malnutrition.

Landscape of Health-Related Quality of Life in Patients With Early-Stage Pancreatic Cancer Receiving Adjuvant or Neoadjuvant Chemotherapy: A Systematic Literature Review

OBJECTIVES

Pancreatic resection is associated with postoperative morbidity and reduced quality of life (QoL). A systematic literature review was conducted to understand the patient-reported outcome measure (PROM) landscape in early-stage pancreatic cancer (PC).

METHODS

Databases/registries (through January 24, 2019) and conference abstracts (2014-2017) were searched. Study quality was assessed using the Newcastle-Ottawa Scale/Cochrane risk-of-bias tool. Searches were for general (resectable PC, adjuvant/neoadjuvant, QoL) and supplemental studies (resectable PC, European Organisation for Research and Treatment of Cancer QoL Questionnaire [QLQ] - Pancreatic Cancer [PAN26]).

RESULTS

Of 750 studies identified, 39 (general, 22; supplemental, 17) were eligible: 32 used QLQ Core 30 (C30) and/or QLQ-PAN26, and 15 used other PROMs. Baseline QLQ-C30 global health status/QoL scores in early-stage PC were similar to all-stage PC reference values but lower than all-stage-all-cancer values. The QoL declined after surgery, recovered to baseline in 3 to 6 months, and then generally stabilized. A minimally important difference (MID) of 10 was commonly used for QLQ-C30 but was not established for QLQ-PAN26.

CONCLUSIONS

In early-stage PC, QLQ-C30 and QLQ-PAN26 are the most commonly used PROMs. Baseline QLQ-C30 global health status/QoL scores suggested a high humanistic burden. Immediately after surgery, QoL declined but seemed stable over the longer term. The QLQ-C30 MID may elucidate the clinical impact of treatment on QoL; MID for QLQ-PAN26 needs to be established.

Psychometric performance of the PAncreatic CAncer disease impact (PACADI) score

BACKGROUND/OBJECTIVE

Pancreatic Cancer Disease Impact (PACADI) score measures the impact of pancreatic cancer (PC) on important health dimensions, selected by patients. The aim of this single center study was to test the psychometric performance of the Pancreatic Cancer Disease Impact (PACADI) score.

METHODS

Patients with suspected pancreatic cancer (PC) completed PACADI, the EuroQol-5D (EQ-5D index) and Edmonton Symptom Assessment System (ESAS) in this longitudinal observational study. Measures were compared across patients with PC (n = 210), other malignant lesions (OML) (n = 109) and non-malignant lesions (NML) (n = 41). Associations, test-retest and internal consistency reliability, longitudinal changes, sensitivity to change and prediction of mortality during the first year were examined in patients with PC.

RESULTS

The three measures discriminated between PC and OML. The PACADI score correlated strongly at baseline (n = 199)/after three months (n = 85) with the EQ-5D index and ESAS "sense of well-being" (0.64 and 0.66/0.73 and 0.69, p < 0.001, respectively), showed high test-retest reliability (ICC 0.84) and very good internal consistency reliability (Cronbach's alpha 0.81-0.85) across all visits. Scores improved over time at 3, 6, 9 and 12 months for survivors, and standardized response mean (SRM) for improvement between 2 and 3 months (n = 44) was 0.80 (PACADI), -0.59 (EQ-5D index) and 0.69 (ESAS "sense of well-being"). The PACADI score significantly predicted mortality within the first year (p = 0.02) in contrast to the EQ-5D index and ESAS "sense of well-being".

CONCLUSION

This study showed satisfactory psychometric performance of the PACADI score. The results support its use in clinical practice and intervention trials.

Long-term Quality of Life and Gastrointestinal Functional Outcomes After Pancreaticoduodenectomy

OBJECTIVE

To perform a comprehensive assessment of long-term quality of life (QOL) and gastrointestinal (GI) function in patients following pancreaticoduodenectomy (PD).

SUMMARY OF BACKGROUND DATA

Survival after PD has greatly improved and thus has resulted in a larger population of survivors, yet long-term QOL and GI function after PD is largely unknown.

METHODS

Patients were identified from a global online support group. QOL was measured using the Short Form-36, while GI function was assessed using the Gastrointestinal Symptom Rating Scale. QOL and GI function were analyzed across subgroups based on time after PD. QOL was compared with preoperative measurements and with established values of a general healthy population (GHP). Multivariate linear regression was used to identify predictors of QOL.

RESULTS

Of the 7605 members of the online support group, 1102 responded to the questionnaire with 927 responders meeting inclusion criteria. Seven hundred seventeen (77.3%) of these responders underwent PD for malignancy. Mean age was 57 ± 12 years and 327 (35%) were male. At the time of survey, patients were 2.0 (0.7, 4.3) years out from surgery, with a maximum 30.7-year response following PD. Emotional and physical domains of QOL improved with time and surpassed preoperative levels between 6 months and 1 year after PD (both P < 0.001). Each GI symptom worsened over time (all P < 0.001). Independent predictors of general QOL in long-term survivors (> 5 years) included total GSRS score [β = -1.70 (-1.91, -1.50)], female sex [β = 3.58 (0.67, 6.46)], and being a cancer survivor [β = 3.93 (0.60, 7.25)].

CONCLUSIONS

Long-term QOL following PD improves over time, however never approaches that of a GHP. GI dysfunction persists in long-term survivors and is an independent predictor of poor QOL. Long-term physical, psychosocial, and GI functional support after PD is encouraged.

The effect of centralization on short term outcomes of pancreatoduodenectomy in a universal health care system

BACKGROUND

Centralization of pancreatic resections is advocated due to a volume-outcome association. Pancreatic surgery is in Norway currently performed only in five teaching hospitals. The aim was to describe the short-term outcomes after pancreatoduodenectomy (PD) within the current organizational model and to assess for regional disparities.

METHODS

All patients who underwent PD in Norway between 2012 and 2016 were identified. Mortality (90 days) and relaparotomy (30 days) were assessed for predictors including demographic data and multi-visceral or vascular resection. Aggregated length-of-stay and national and regional incidences of the procedure were also analysed.

RESULTS

A total of 930 patients underwent PD during the study period. In-hospital mortality occurred in 20 patients (2%) and 34 patients (4%) died within 90 days. Male gender, age, multi-visceral resection and relaparotomy were independent predictors of 90-day mortality. Some 131 patients (14%) had a relaparotomy, with male gender and multi-visceral resection as independent predictors. There was no difference between regions in procedure incidence or 90-day mortality. There was a disparity within the regions in the use of vascular resection (p = 0.021).

CONCLUSION

The short-term outcomes after PD in Norway are acceptable and the 90-day mortality rate is low. The outcomes may reflect centralization of pancreatic surgery.

'I want to know why and need to be involved in my own care…': a qualitative interview study with liver, bile duct or pancreatic cancer patients about their experiences with involvement in care

PURPOSE

Patients' involvement in their own care is important for those with upper abdominal tumours. Care is often conducted according to standardized fast-track care programs (FTCP), and a shorter hospital stay is one of the goals. However, there is no research providing an in-depth perspective on patients' experiences of involvement in care. In this qualitative study, we explored experiences of involvement among patients who had surgery for upper abdominal tumours and were cared for according to an FTCP.

METHODS

Qualitative in-depth face-to-face interviews about patient involvement in care were conducted with 20 patients who had surgery for the liver, bile duct, or pancreatic cancer using an open-interview guide.

RESULTS

The most important findings are that customized information and active dialogue about care decisions stimulate patient involvement. We identified three themes from the analysed data: involvement depended on the quality of information, communication and involvement during the care period, and safety at discharge.

CONCLUSIONS

Individualized care and continuous information about treatment and care goals in the FTCP during the care process create trust between patients and healthcare professionals and increase patient experiences of involvement.
