Quality of Life in Patients With Pancreatic Cancer and Their Caregivers: A Systematic Review

Emotional distress, brain functioning, and biobehavioral processes in cancer patients: a neuroimaging review and future directions

Despite emerging evidence that distress and adversity can contribute to negative health outcomes in cancer, little is known about the brain networks, regions, or circuits that can contribute to individual differences in affect/distress states and health outcomes in treated cancer patients. To understand the state-of-the-science in this regard, we reviewed neuroimaging studies with cancer patients that examined the associations between negative affect (distress) and changes in the metabolism or structure of brain regions. Cancer patients showed changes in function and/or structure of key brain regions such as the prefrontal cortex, thalamus, amygdala, hippocampus, cingulate cortex (mainly subgenual area), hypothalamus, basal ganglia (striatum and caudate), and insula, which are associated with greater anxiety, depression, posttraumatic stress disorder (PTSD) symptoms, and distress. These results provide insights for understanding the effects of these psychological and emotional factors on peripheral stress-related biobehavioral pathways known to contribute to cancer progression and long-term health outcomes. This line of work provides leads for understanding the brain-mediated mechanisms that may explain the health effects of psychosocial interventions in cancer patients and survivors. A multilevel and integrated model for distress management intervention effects on psychological adaptation, biobehavioral processes, cancer pathogenesis, and clinical outcomes is proposed for future research.

Experiences and supportive care needs of UK patients with pancreatic cancer: a cross-sectional questionnaire survey

OBJECTIVES

Patients diagnosed with pancreatic cancer have the poorest survival prognosis of any cancer. This survey aimed to describe their experiences of care and supportive care needs to inform future service provision.

DESIGN

Cross-sectional questionnaire survey of patients with pancreatic cancer in the UK.

SETTING

Individuals at any stage along the care pathway were recruited via five National Health Service sites in the UK, and online, from January to June 2018.

PARTICIPANTS

274 individuals completed the questionnaire (78% (215) were completed online). Approximately half of participants were diagnosed within the last year (133/274). Of 212 providing gender details, 82 were male and 130 were female. Ninety per cent (192/213) described themselves as White British.

PRIMARY OUTCOME MEASURES

Experiences of communication and information; involvement in treatment decisions; supportive care needs.

RESULTS

Communication with, and care received from, clinical staff were generally reported positively. However, 29% (75/260) of respondents did not receive enough information at diagnosis, and 10% (25/253) felt they were not involved in decisions about their treatment, but would have liked to be. Supportive care needs were greatest in psychological and physical/daily living domains. 49% (108/221) of respondents reported one or more moderate/high unmet needs within the last month, of which the most commonly reported were: dealing with uncertainty about the future; fears about the cancer spreading; not being able to do things they used to; concerns about those close to them; lack of energy; anxiety; feelings of sadness and feeling down/depressed. Experiences were poorer, and unmet supportive care needs greater, in patients with unresectable disease.

CONCLUSIONS

Patients with pancreatic cancer have unmet information and support needs across the cancer trajectory. Psychological and physical support appears to be the biggest gap in care. Needs should be assessed and supportive care interventions implemented from the point of diagnosis, and monitored regularly to help patients live as good a quality of life as possible.

Health-related quality of life and medical comorbidities in older patients with pancreatic adenocarcinoma: An analysis using the 1998-2011 surveillance, epidemiology, and end results-medicare health outcomes survey data

OBJECTIVES

This study compares health-related quality of life (HRQoL) of older patients with pancreatic ductal adenocarcinoma (PDAC) to controls without cancer, and examines the impact of medical comorbidities on HRQoL.

MATERIALS AND METHODS

We conducted a case-control study using the 1998-2011 Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) linked dataset. Cases were Medicare beneficiaries aged 65 and older diagnosed with PDAC (N = 128) and matched controls were without a history of cancer (N = 512). We used the Short Form 36 (SF-36) and Veterans-RAND-12 (VR-12) to examine HRQoL and calculated mental (MCS) and physical (PCS) component scores. Linear regression and mixed effects models were used to examine the impact of medical comorbidities on MCS and PCS for cases and controls, respectively.

RESULTS

Cases reported significantly poorer PCS (29.3 vs. 36.3) and MCS (44.8 vs. 49.9) compared to controls. Comorbidities were significantly associated with lower PCS and MCS in controls. However, neither total number of comorbidities or comorbidities grouped by organ systems (cardiopulmonary disease, musculoskeletal disease, diabetes) were significantly related to PCS or MCS for cases. Comparison of regression coefficients estimates did not indicate that lack of significance was due to differences in sample size.

CONCLUSIONS

The results of this study highlight the poor HRQoL reported by older patients with PDAC. HRQoL scores were very low in this population, particularly in physical health status, which were not explained by comorbidities.

Gold Nanoparticles sensitize pancreatic cancer cells to gemcitabine

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest solid cancers with dismal prognosis. Several mechanisms that are mainly responsible for aggressiveness and therapy resistance of PDAC cells include epithelial to mesenchymal transition (EMT), stemness and Mitogen Activated Protein Kinase (MAPK) signaling. Strategies that inhibit these mechanisms are critically important to improve therapeutic outcome in PDAC. In the current study, we wanted to investigate whether gold nanoparticles (AuNPs) could sensitize pancreatic cancer cells to the chemotherapeutic agent gemcitabine. We demonstrated that treatment with AuNPs of 20 nm diameter inhibited migration and colony forming ability of pancreatic cancer cells. Pre-treatment with AuNPs sensitized pancreatic cancer cells to gemcitabine in both viability and colony forming assays. Mechanistically, pre-treatment of pancreatic cancer cells with AuNPs decreased gemcitabine induced EMT, stemness and MAPK activation. Taken together, these findings suggest that AuNPs could be considered as a potential agent to sensitize pancreatic cancer cells to gemcitabine.

Association between chronological depressive changes and physical symptoms in postoperative pancreatic cancer patients

Background

Pancreatic cancer (PC) has poorer prognosis and higher surgical invasiveness than many other cancers, with associated psychiatric symptoms including depression and anxiety. Perioperative depression has not been investigated in PC patients regarding surgical stress and relevant interventions.

Methods

We evaluated chronological depressive changes and subjective physical symptoms in surgically treated PC patients preoperatively and at 3 and 6 months postoperatively.

Enrolled patients undergoing pancreatic tumor surgery completed questionnaires based on the Self-Rating Depression Scale (SDS) and Functional Assessment of Cancer Therapy for Patients with Hepatobiliary Cancer (FACT-Hep) preoperatively, and at 3 and 6 months postoperatively. Responses were analyzed with JMP® Pro using one-way and two-way ANOVA, Spearman’s rank correlation coefficient, and multiple regression analysis.

Results

Malignancy was diagnosed in 73 of 101 patients postoperatively; SDS score was significantly higher in these patients than in those with benign tumors at all timepoints: malignant/benign, 41.8/37.9 preoperatively (p = 0.004); 43.5/37.8 3 months postoperatively (p = 0.006); and 42.9/37.7 6 months postoperatively (p = 0.020). SDS scores were significantly higher in patients < 65 years old with malignancy at 3 months than at 6 months postoperatively (44.6/42.5, p = 0.046) and in patients with malignancy who underwent pancreaticoduodenectomy at 3 months postoperatively than preoperatively (43.4/41.1; p = 0.028). SDS scores moderately correlated with 8 physical symptom-related FACT-Hep items 3 months postoperatively (p < 0.05), showing low-to-moderate correlation with 16 physical symptom-related FACT-Hep items at 6 months postoperatively (p < 0.05). Multiple regression analysis of FACT-Hep symptoms significantly correlated with SDS scores revealed the following significant variables: “lack of energy” (p < 0.000) and “pain” (p = 0.018) preoperatively (R² = 0.43); “able to perform usual activities” (p = 0.031) and “lack of energy” (p < 0.000) at 3 months postoperatively (R² = 0.51); and “stomach swelling or cramps” (p = 0.034) and “bowel control” (p = 0.049) at 6 months postoperatively (R² = 0.52).

Conclusions

PC patients experience persistently high levels of depression preoperatively through 6 months postoperatively, with associated subjective symptoms including pain and gastrointestinal symptoms.

Using photography to explore psychological distress in patients with pancreatic cancer and their caregivers: a qualitative study

PURPOSE

The quality of life (QOL) experiences of patients with pancreatic cancer and their caregivers is poorly understood. Psychological distress is high, but few studies examine the factors associated with psychological distress. The purpose of this study is to gain a richer understanding of the factors associated with psychological distress from patient and caregiver perspectives.

METHODS

Twenty participants (13 patients, 7 caregivers) completed group discussions on the experiences of living with pancreatic cancer. Using photovoice methods, participants took photographs and provided narratives depicting the distress they experienced. Participant-produced photographs and group discussion transcripts were analyzed to identify key themes using thematic analysis.

RESULTS

Commonalities between patient and caregiver sources of distress emerged despite their distinct roles. Findings revealed four major areas of distress: diagnosis of an unexpected advanced cancer, changes in roles and identity, management of weight loss and gastrointestinal problems, and fear of the future. Participants also discussed unique perspectives such as the stigma of pancreatic cancer and caregiver guilt.

CONCLUSIONS

Photovoice provides a unique insight into the lives of patients with pancreatic cancer and their caregivers. Our findings contribute to the gap in the current literature by providing a better understanding of the factors surrounding pancreatic cancer distress. We also identify several clinical recommendations to improve cancer care delivery and areas for future research.
