Prodromal depression and anxiety are associated with worse treatment compliance and survival among patients with pancreatic cancer

Multidisciplinary Standards and Evolving Therapies for Patients With Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDA) is a challenging disease that presents at an advanced stage and results in many symptoms that negatively influence patients' quality of life and reduce their ability to receive effective treatment. Early implementation of expert multidisciplinary care with nutritional support, exercise, and palliative care for both early-stage and advanced disease promises to maintain or improve the patients' physical, social, and psychological well-being, decrease aggressive interventions at the end of life, and ultimately improve survival. Moreover, advances in treatment strategies in the neoadjuvant and metastatic setting combined with novel therapeutic agents targeting the key drivers of the disease are leading to improvements in the care of patients with pancreatic cancer. Here, we emphasize the multidisciplinary supportive and therapeutic care of patients with PDA, review current guidelines and new developments of neoadjuvant and perioperative treatments for localized disease, as well as the treatment standards and the evolving field of precision oncology and immunotherapies for advanced PDA.

Compartmentalized role of xCT in supporting pancreatic tumor growth, inflammation and mood disturbance in mice

xCT (Slc7a11), the specific subunit of the cystine/glutamate antiporter system xc-, is present in the brain and on immune cells, where it is known to modulate behavior and inflammatory responses. In a variety of cancers -including pancreatic ductal adenocarcinoma (PDAC)-, xCT is upregulated by tumor cells to support their growth and spread. Therefore, we studied the impact of xCT deletion in pancreatic tumor cells (Panc02) and/or the host (xCT-/- mice) on tumor burden, inflammation, cachexia and mood disturbances. Deletion of xCT in the tumor strongly reduced tumor growth. Targeting xCT in the host and not the tumor resulted only in a partial reduction of tumor burden, while it did attenuate tumor-related systemic inflammation and prevented an increase in immunosuppressive regulatory T cells. The latter effect could be replicated by specific xCT deletion in immune cells. xCT deletion in the host or the tumor differentially modulated neuroinflammation. When mice were grafted with xCT-deleted tumor cells, hypothalamic inflammation was reduced and, accordingly, food intake improved. Tumor bearing xCT-/- mice showed a trend of reduced hippocampal neuroinflammation with less anxiety- and depressive-like behavior. Taken together, targeting xCT may have beneficial effects on pancreatic cancer-related comorbidities, beyond reducing tumor burden. The search for novel and specific xCT inhibitors is warranted as they may represent a holistic therapy in pancreatic cancer.

Integrative Oncology Approaches to Reduce Recurrence of Disease and Improve Survival

PURPOSE OF REVIEW

After a cancer diagnosis, patients ask what they can do in addition to the recommended treatments to increase their survival. Many turn to integrative medicine modalities and lifestyle changes to improve their chances of survival. Numerous studies have demonstrated that lifestyle changes can significantly improve survival rates for cancer patients. Less support exists for the use of natural products or supplements to improve cancer survival. In this manuscript, we review key findings and evidence in the areas of healthy eating habits, physical activity, stress management and social support, and sleep quality, as well as natural products and supplements as they relate to the cancer recurrence and survival.

RECENT FINDINGS

While more research is needed to fully understand the mechanisms underlying the associations between lifestyle changes and cancer survival, findings suggest that lifestyle modifications in the areas of diet, physical activity, stress management and social support, and sleep quality improve clinical cancer outcomes. This is especially true for programs that modify more than one lifestyle habit. To date, outside of supplementing with vitamin D to maintain adequate levels, conflicting conclusion within the research remain regarding the efficacy of using natural products or supplement to improve cancer recurrence of disease or cancer survival. A call for further research is warranted. Lifestyle screening and counseling should be incorporated into cancer treatment plans to help improve patient outcomes. While the scientific community strives for the pursuit of high-quality research on natural products to enhance cancer survival, transparency, dialogue, and psychological safety between patients and clinicians must continue to be emphasized. Proactive inquiry by clinicians regarding patients' supplement use will allow for an informed discussion of the benefits and risks of natural products and supplements, as well as a re-emphasis of the evidence supporting diet and other lifestyle habits to increase survival.

Pancreatic cancer progression and mortality predicted by depression and anxiety: a systematic review and meta-analysis protocol

Although the relationship between psychological factors and pancreatic cancer outcomes has been widely discussed, controversy remains. We will for the first time systematically summarize the literature to explore the correlation of anxiety and depression to the prognosis of patients with pancreatic cancer. The findings will fill existing research gaps, informing healthcare providers about better psychological care and medical treatment. The following databases will be retrieved from their inception to July 2023: Cochrane Library, MEDLINE (PubMed), Web of Science, EMBASE, and four Chinese databases (Chinese National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Literature Database, and Chongqing VIP Chinese Science and Technology Periodical Database). The World Health Organization Clinical Trials Registry, Chinese Clinical Registry, and ClinicalTrials.gov will be searched to identify other related studies. A manual search will be performed to identify missing eligible studies based on the reference list of selected articles. The search will focus on studies published in Chinese or English. To assess the risk of bias in the selected articles, Newcastle-Ottawa Quality Assessment Scale (NOS) will be used for the cohort study. Funnel plots and Egger's test will be used to assess whether publication bias exists. Moreover, the Grading of Recommendations Assessment Development and Evaluation (GRADE) will be utilized to analyze the credibility of the results from selected articles. Two independent evaluators will implement the study selection and data extraction, as well as evaluate the risk of bias and evidence quality. Data will be analyzed using Stata 16.0. Trial registration: PROSPERO registration number is CRD42022366232.

Poor Access to Mental Healthcare is Associated with Worse Postoperative Outcomes Among Patients with Gastrointestinal Cancer

BACKGROUND

Mental health has an important role in the care of cancer patients, and access to mental health services may be associated with improved outcomes. Thus, poor access to psychiatric services may contribute to suboptimal cancer treatment. We conducted a geospatial analysis to characterize psychiatrist distribution and assess the impact of mental healthcare shortages with surgical outcomes among patients with gastrointestinal cancer.

METHODS

Medicare beneficiaries with mental illness diagnosed with complex gastrointestinal cancers between 2004 and 2016 were identified in the Surveillance, Epidemiology, and End Results (SEER)-Medicare registry. National Provider Identifier-registered psychiatrist locations were mapped and linked to SEER-Medicare records. Regional access to psychiatric services was assessed relative to textbook outcome, a composite assessment of postoperative complications, prolonged length of stay, 90-day readmission and mortality.

RESULTS

Among 15,714 patients with mental illness and gastrointestinal cancer, 3937 were classified as having high access to psychiatric services while 3910 had low access. On multivariable logistic regression, areas with low access had higher risk of worse postoperative outcomes. Specifically, individuals residing in areas with low access had increased odds of prolonged length of stay (OR 1.11, 95%CI 1.01-1.22; p = 0.028) and 90-day readmission (OR 1.19, 95%CI 1.08-1.31; p < 0.001), as well as decreased odds of textbook outcome (OR 0.85, 95%CI 0.77-0.93; p < 0.001) and discharge to home (OR 0.89, 95%CI 0.80-0.99; p = 0.028).

CONCLUSION

Patients with mental illness and lower access to psychiatric services had worse postoperative outcomes. Policymakers and providers should prioritize incorporating mental health screening and access to psychiatric services to address disparities among patients undergoing gastrointestinal surgery.

Health-related quality of life and survival outcomes for patients with major depressive disorder and anxiety: A longitudinal study in pancreatic ductal adenocarcinoma

BACKGROUND

Major depressive disorder (MDD) and anxiety were recognized in treating pancreatic ductal adenocarcinoma (PDAC). This longitudinal study identified risk factors for MDD and anxiety and established associations with patients' quality of life (QoL) and survival outcomes.

MATERIALS AND METHODS

We used PHQ-9 and GAD-7 questionnaires to diagnose MDD and anxiety in PDAC patients between October 2021 and March 2022 at a Chinese center. Characteristics and clinical data were analyzed for risk factors and EORTC QLQ-C30 questionnaire was administered for QoL before the first chemotherapy. Furthermore, chemotherapy compliance and 1-year survival were compared during follow-up.

RESULTS

MDD and anxiety occurred in 51.8% and 44.7% of 114 patients over the half-year period. Employment at work (odds ratio [OR]: 5.514, p = 0.001; OR: 3.420, p = 0.011) was an independent risk factor, while radical surgery (OR: 0.342, p = 0.034; OR: 0.238, p = 0.004) was a protective factor. Several aspects of decreased QoL were discovered after their onsets. Higher incidences of physical disorders (p = 0.004; p < 0.001), mental disorders (p = 0.001; p < 0.001), anti-therapy emotions (p = 0.002; 0.001), and chemotherapy suspensions (p = 0.001; p = 0.043) were observed. Furthermore, the 1-year mortalities for all patients and those receiving radical surgeries were correlated with MDD (p = 0.007; 0.036) and anxiety (p = 0.010; 0.031).

CONCLUSIONS

MDD and anxiety are common in PDAC patients and correlated with poor QoL and survivals. Therefore, appropriate mental management is required in future.

Profile of the Postoperative Care Provided for Patients With Pancreatic and Periampullary Cancers by Family and Unpaid Caregivers

PURPOSE

Patients with pancreatic and periampullary cancers may experience significant reduction in their quality of life and often rely on family and unpaid caregivers for assistance after surgery. However, as caregivers are not systematically identified, little is known about the nature, difficulty, and personal demands of assistance they provide. We aim to assess the frequency and difficulty of specific assistance caregivers provide and identify potential interventions that could alleviate the caregiving demands.

METHODS

This was a prospective, multi-institutional study of caregivers accompanying patients with periampullary and pancreatic cancer at their 1-month postpancreatectomy office visit. An instrument that drew heavily on the National Study of Caregiving was administered to caregivers.

RESULTS

Of 240 caregivers, more than half (58.3%) of caregivers were the patients' spouse, a quarter (25.8%) were daughters or sons, 12.9% other relatives, and 2.9% nonrelatives. Caregivers least frequently provided assistance with transportation (14.6% every day) and most frequently provided assistance with housework (65.0% every day, P = .003) and diet (56.5% every day, P = .004). Caregivers reported the least difficulty helping patients with exercise (1.5% somewhat difficult). Caregivers reported significantly more difficulty with assisting with housework (14.5% somewhat difficult, P < .001) and diet (14.9% somewhat difficult, P < .001). Caregivers identified the immediate postpancreatectomy and early discharge periods as the most stressful phases. They also reported having received very little information about available services that could have supported their efforts.

CONCLUSION

Caregivers of patients with periampullary or pancreatic cancer provide considerable assistance in the postoperative period and many reported difficulty in assisting with housework and diet. Work is needed to better prepare and support caregivers to better enable them to adequately care for patients with pancreas and periampullary cancer.

Exploring the Link Between Pancreatic Neuroendocrine Tumors and Depression: A Case Study

This case probes the potential temporal relationship between pancreatic neuroendocrine tumor (PNET) and depression. This patient has chronic symptoms of depression with no formal diagnosis until within a year of doctors suspecting her diagnosis of pancreatic cancer. An excisional biopsy confirmed a grade 1 neuroendocrine tumor (NET) in the pancreas, and postoperative psychiatric consultation confirmed continued elevated depression. This report presents an illustrative example of the ongoing research questions surrounding the relationship between the timing of a depression diagnosis and a PNET diagnosis. The depression-before-diagnosis relationship in pancreatic cancer patients is an observation that warrants further studies as depression could be a valuable early warning sign of pancreatic cancer.

Prevalence, risk factors and prognostic value of anxiety and depression in recurrent glioma patients

Anxiety and depression are frequently noticed in glioma patients, while few studies report this issue in recurrent glioma patients. Hence, this study aimed to evaluate the prevalence of anxiety and depression, as well as their risk factors and prognostic value in recurrent glioma patients. Eighty recurrent glioma patients, 40 newly-diagnosed glioma patients, and 40 healthy controls were enrolled in this study. Then, the Hospital Anxiety and Depression Scale for anxiety (HADS-A) and for depression (HADS-D) were used to assess the anxiety and depression status of all subjects. The HADS-A score (8.6 ± 3.3 vs. 7.0 ± 2.9 vs. 4.3 ± 2.5), anxiety rate (58.8% vs. 32.5% vs. 10.0%), HADS-D score (7.9 ± 3.0 vs. 6.9 ± 3.1 vs. 4.0 ± 2.6), and depression rate (45.0% vs. 30.0% vs. 7.5%) were all highest in recurrent glioma patients, followed by newly-diagnosed glioma patients, and were lowest in healthy controls (all P < 0.001). Furthermore, female sex (vs. male sex) was independently correlated with anxiety (odds ratio (OR): 3.042, P = 0.029); meanwhile, higher World Health Organization (WHO) pathological grade was independently correlated with depression (OR: 2.573, P = 0.019) in recurrent glioma patients. Additionally, anxiety was correlated with shortened progression-free survival (PFS) (P = 0.028) and overall survival (OS) (P = 0.047), while depression only had a correlation trend with shortened PFS (without statistical significance) (P = 0.069) and was associated with shortened OS (P = 0.035) in recurrent glioma patients. The prevalence of anxiety and depression is high in recurrent glioma patients, which relates to gender, WHO pathological grade, and estimates worsen survival.

Suicidal Ideation Among Patients with Gastrointestinal Cancer

BACKGROUND

Mental illness (MI) and suicidal ideation (SI) often are associated with a diagnosis of cancer. We sought to define the incidence of MI and SI among patients with gastrointestinal cancers, as well as ascertain the predictive factors associated with SI.

METHODS

Patients diagnosed between 2004 and 2016 with stomach, liver, pancreatic, and colorectal cancer were identified from the SEER-Medicare database. County-level social vulnerability index (SVI) was extracted from the Centers for Disease Control database. Multivariable logistic regression was used to identify factors associated with SI.

RESULTS

Among 382,266 patients, 83,514 (21.9%) individuals had a diagnosis of MI. Only 1410 (0.4%) individuals experienced SI, and 359 (0.1%) committed suicide. Interestingly, SI was least likely among patients with pancreatic cancer (ref: hepatic cancer; odds ratio [OR] 0.67, 95% confidence interval [CI] 0.52-0.86; p = 0.002), as well as individuals with stage III/IV disease (OR 0.59, 95% CI 0.52-067; p < 0.001). In contrast, male (OR 1.34, 95% CI 1.19-1.50), White (OR 1.34, CI 1.13-1.59), and single (OR 2.03, 95% CI 1.81-2.28) patients were at higher odds of SI risk (all p < 0.001). Furthermore, individuals living in relative privilege (low SVI) had markedly higher risk of SI (OR 1.33, 95% CI 1.14-1.54; p < 0.001). Moreover, living in a county with a shortage of mental health professionals was associated with increased odds of developing SI (OR 1.21, 95% CI 1.04-1.40; p = 0.012).

CONCLUSIONS

Oncology care teams should incorporate routine mental health and SI screening in the treatment of patients with gastrointestinal cancers, as well as target suicide prevention towards patients at highest risk.

Pancreatic cancer and depression

Pancreatic cancer is a highly devastating disease with high mortality rates. Even patients who undergo potential curative surgery have a high risk for recurrence. The incidence of depression and anxiety are higher in patients with cancer than the general population. However, patients with pancreatic cancer are at most of risk of both depression and anxiety and there seems to be a biological link. In some patients, depression seems to be a precursor to pancreatic cancer. In this article we discuss the biological link between depression anxiety and hepatobiliary malignancies and discuss treatment strategies.

Disparities in the medical expenditures of patients with cancer and concomitant mental disorder: analyzing the effects of diagnosis sequence order

BACKGROUND

Cancer is the leading cause of death in Taiwan. Medical expenditures related to cancer accounted for 44.8% of all major illness insurance claims in Taiwan. Prior research has indicated that the dual presence of cancer and mental disorder in patients led to increased medical burden. Furthermore, patients with cancer and concomitant mental disorder could incur as much as 50% more annual costs than those without. Although previous studies have investigated the utilization of patients with both diseases, the effects of morbidity sequence order on patient costs are, however, uncertain. This study explored medical expenditures linked with the comorbidity of cancer and mental disorder, with a focus on the impact of diagnosis sequence order.

METHODS

This population-based retrospective matched cohort study retrieved patients with cancer and mental disorder (aged ≥ 20 years) from the Ministry of Health and Welfare Data Science Center 2005-2015 database. 321,045 patients were divided based on having one or both diseases, as well as on the sequence of mental disorder and cancer diagnosis. Study subjects were paired with comparison counterparts free of both diseases using Propensity Score Matching at a 1:1 ratio. Annual Cost per Patient Linear Model (with a log-link function and gamma distribution) was used to assess the average annual cost, covarying for socio-demographic and clinical factors. Binomial Logistic Regression was used to evaluate factors associated with the risk of high-utilization.

RESULTS

The "Cancer only" group had higher adjusted mean annual costs (NT$126,198), more than 5-times that of the reference group (e^β: 5.45, p < 0.001). However, after exclusion of patients with non-cancer and inclusion of diagnosis sequence order for patients with cancer and concomitant mental disorder, the post-cancer mental disorder group had the highest expenditures at over 13% higher than those diagnosed with only cancer on per capita basis (e^β: 1.13, p < 0.001), whereas patients with cancer and any pre-existing mental disorder incurred lower expenditures than those with only cancer. The diagnosis of post-cancer mental disorder was significantly associated with high-utilization (OR = 1.24; 95% CI: 1.047-1.469). Other covariates associated with high-utilizer status included female sex, middle to old age, and late stage cancer.

CONCLUSION

Presence of mental disorder prior to cancer had a diminishing effect on medical utilization in patients, possibly indicating low medical compliance or adherence in patients with mental disorder on initial treatments after cancer diagnosis. Patients with post-cancer mental disorder had the highest average annual cost. Similar results were found in the odds of reaching high-utilizer status. The follow-up of cancer treatment for patients with pre-existing mental disorders warrants more emphasis in an attempt to effectively allocate medical resources.

IDO1 Is a Therapeutic Target for Pancreatic Cancer-Associated Depression

Metabolites of tryptophan degradation are known to alter mood. Their effects have only been superficially examined in the context of pancreatic cancer. Herein, we study the role of indoleamine 2,3-dioxygenase 1 (IDO1), an enzyme important in the conversion of tryptophan to kynurenine, in a murine model of pancreatic cancer-associated depression. Behavioral tests (open field, forced swim, tail suspension, and elevated plus maze) and biochemical assays (LC-MS metabolomics) were used to characterize a depressive-phenotype in tumor-bearing mice (relative to non-tumor-bearing mice). In addition, we determine whether pharmacologic blockade of IDO1 affects mood in tumor-bearing mice. Immunocompetent mice bearing orthotopic pancreatic tumors exhibit depressive-like behavior relative to non-tumor-bearing mice. Pancreatic tumors strongly express IDO1. Consequently, serum kynurenine levels in tumor-bearing mice are elevated relative to non-tumor-bearing mice. Tumor-bearing mice treated with epacadostat, an IDO1 inhibitor, exhibited improved mood relative to mice receiving vehicle. There was a 95% reduction in serum kynurenine levels in mice receiving epacadostat relative to mice treated with vehicle. As confirmatory evidence of on-target activity, tumors of mice treated with epacadostat exhibited a compensatory increase in IDO1 protein levels. Escitalopram, an approved antidepressant, was ineffective at improving mood in tumor-bearing mice as measured by behavioral assays and did not affect kynurenine levels. Neither epacadostat, nor escitalopram, affected overall survival relative to vehicle. Mice with pancreatic cancer exhibit depressive-like behavior. Epacadostat was effective as an antidepressant for pancreatic cancer-associated depression in mice. These data offer a rationale to consider IDO1 inhibition as a therapeutic strategy to mitigate depressive symptoms in patients with pancreatic cancer.

A long waiting time from diagnosis to treatment decreases the survival of non-small cell lung cancer patients with stage IA1: A retrospective study

Objective

The prognostic effect of delayed treatment on stage IA1 non-small cell lung cancer (NSCLC) patients is still unclear. This study aimed to explore the association between the waiting time before treatment and the prognosis in stage IA1 NSCLC patients.

Methods

Eligible patients diagnosed with pathological stage IA1 NSCLC were included in this study. The clinical endpoints were overall survival (OS) and cancer-specific survival (CSS). The Kaplan-Meier method, the Log-rank test, univariable, and multivariable Cox regression analyses were used in this study. Propensity score matching was used to reduce the bias of data distribution.

Results

There were eligible 957 patients in the study. The length of waiting time before treatment stratified the survival in patients [&lt;3 months vs. ≥3-months, unadjusted hazard ratio (HR) = 0.481, P = 0.007; &lt;2 months vs. ≥2-months, unadjusted HR = 0.564, P = 0.006; &lt;1 month vs. ≥1-month, unadjusted HR = 0.537, P = 0.001]. The 5-year CSS rates were 95.0% and 77.0% in patients of waiting time within 3 months and over 3 months, respectively. After adjusting for other confounders, the waiting time was identified as an independent prognostic factor.

Conclusions

A long waiting time before treatment may decrease the survival of stage IA1 NSCLC patients. We propose that the waiting time for those patients preferably is less than one month and should not exceed two months.

Managing inoperable pancreatic cancer: the role of the pancreaticobiliary physician

Despite our understanding of pancreatic cancer (PC), the majority of patients with this disease are incurable. Both the incidence and mortality rates for PC have increased over the last decade. At diagnosis, the majority of patients have locally advanced PC, less than 20% of patients are eligible for potentially curative resection and approximately one-third have metastatic disease. The combination of frequent advanced presentation, low resection rates and poor responses to chemotherapy make PC one of the most lethal tumours. The treatment goals are to maintain local control, manage tumour-related morbidities and improve quality of life. Patients with inoperable PC are likely to experience significant symptoms associated with their tumour, including pancreatic insufficiency, nutritional deficiencies, pain, biliary obstruction, gastric outlet obstruction and diabetes. As a result, guidance on the management of patients with inoperable PC is critical. PC is commonly referred centrally to specialist centres particularly for surgery; however, the majority do not undergo surgical intervention and thus the importance of pancreaticobiliary physicians and endoscopists. This review will focus on the non-operative management of patients with unresectable pancreatic adenocarcinoma and review some of the issues that centralisation has contributed to.
