Health-related quality of life, emotional burden, and neurocognitive function in the first generation of metastatic melanoma survivors treated with pembrolizumab: a longitudinal pilot study

Survivorship outcomes in patients treated with immune checkpoint inhibitors: a scoping review

BACKGROUND

Immune checkpoint inhibitors (ICIs) have become a central part of cancer care. However, the survivorship outcomes in patients treated with ICIs are understudied. Therefore, we conducted a scoping review to evaluate the current status of the field and to establish research gaps regarding survivorship outcomes with ICIs in real-life cohorts.

METHODS

We used the Web of Science, PubMed, and Embase databases to systematically filter published studies with real-life cohorts from January 1, 2010, until October 19, 2022. Studies evaluating at least one survivorship outcome in ICI-treated patients were included.

RESULTS

A total of 39 papers were included. Quality of life (QoL) (n = 23), toxicity burden (n = 16), and psychosocial issues (n = 9) were the most frequently evaluated survivorship outcomes. Anti-PD-1/PD-L1 monotherapy and a response to treatment were associated with better QoL. In addition, the ICIs were associated with grade 3 or higher immune-related adverse events (irAEs) in 10-15% and late/long-term irAEs in 20-30% of the survivors. Regarding psychosocial problems, over 30% of survivors showed evidence of anxiety and depression, and 30-40% of survivors reported neurocognitive impairments.

CONCLUSION

The survivors treated with ICIs have impairments in most survivorship domains. Further research is needed to gather data on the understudied survivorship outcomes like late and long-term effects, fertility, financial toxicity, and return to work in survivors treated with ICIs.

IMPLICATIONS FOR CANCER SURVIVORS

Available evidence demonstrates that a significant portion of survivors treated with ICIs have a significant toxicity burden, lower QoL than the general population, and a high rate of psychosocial problems.

Neuropsychological and central neurologic effects of cancer immunotherapy: the start of a new challenge

INTRODUCTION

Cognitive difficulties are frequently reported after cancer treatments, such as chemotherapy or hormone therapy, and have a negative impact on patients' quality of life. Recently, some studies have shown that new cancer treatments, such as immunotherapy agents, can induce cognitive changes.

METHOD

This review presents the central neurological immune adverse events of immunotherapy treatments including Immune Checkpoint Inhibitors (ICI) and Chimeric Antigen Receptor (CAR) T-cell therapy. The physiopathological mechanisms and risk factors are developed and clinical studies on immunotherapy agents and cognition (among adult patients, using validated questionnaires and/or cognitive tests), psychological factors and quality of life were presented.

RESULTS

Neurological toxicities are frequently observed with CAR-T cell therapies at acute stage, such as the immune effector cell-associated neurotoxicity syndrome (ICANS), inducing cognitive disorders such as disorientation and aphasia. However, few studies have accurately assessed the impact of immunotherapy on cognition. The methodology of these studies is heterogeneous and they mainly included nonspecific self-report questionnaires of cognitive complaints. Variable results have been obtained concerning the cognitive impact of ICI and CAR-T cell several months following immunotherapy: overall, while some studies reported cognitive difficulties (mainly processing speed and executive functions), the majority has not. Although anxiety and depression are frequently reported in patients treated with ICI or CAR-T cells, these symptoms tend to decrease after the start of immunotherapy. The current neurobiological investigations are too fragmentary to explain neurological symptoms and potential cognitive alteration, but neuroinflammation, vascular inflammation, brain blood barrier disruption, and immune cell brain infiltration would constitute common mechanisms relayed by CAR-T and to a lesser degree, ICI.

CONCLUSIONS

Acute neurological toxicities following CAR-T cell therapies are a major issue. Further studies are needed to better assess cognitive difficulties after the initiation of immunotherapy, in particular ICI, to better understand the physiopathology, including imaging studies, and risk factors.

Identification of the PROMs used to assess ICI toxicities and HRQoL in patients receiving immune checkpoint inhibitor treatment in cancer care and their suitability: A systematic review

BACKGROUND

The implementation of patient-reported outcome measures (PROMs) in the clinical identification of immunotherapy toxicities is a complex intervention. There has been very little work evaluating the clinical utility and generalisability of PROMs used after immune checkpoint inhibitor (ICI) treatment to date. We reviewed evidence on the use of PROMs assessing toxicities and health-related quality of life in patients treated with ICIs.

METHODS

PubMed, EMBASE, MEDLINE, PsycInfo, CINAHL, Web of Knowledge, the Cochrane Library were searched (January 2008 - October 2024). Quantitative studies reporting the use of PROMs to identify, assess and manage toxicities at any timepoint and HRQoL associated with ICI treatment in adult patients with cancer were included. A narrative synthesis describes the key characteristics of the PROMs identified.

RESULTS

43 studies were included; 12 on melanoma/skin, 12 on lung and 19 on other cancers. Study designs included 20 randomised controlled trials, 14 cohort studies, six cross-sectional studies and three non-randomised interventional trials. The lack of ICI-specific PROMs was highlighted, particularly as the PROMs used lacked sufficient sensitivity for ICI treatments.

CONCLUSIONS

There is need for an ICI-specific PROM for effective assessment of toxicities and a tailored PROM for assessment of HRQoL. Some suggested key domains by certain studies for ICI-specific PROMs include: (a) ICI-specific items (e.g. certain USD-I and PRO-CTCAE items) to capture symptoms associated with ICI treatments such as rash, myalgia, (b) role, psychological, emotional and social functioning domains within HRQoL assessments and (c) additional patient-reported toxicities not included in existing PROMs. Findings emphasize the importance of using a disease-specific PROM that is applicable, acceptable and sufficiently sensitive to identify toxicities and HRQoL issues across all stages.

Quality of life, neurocognitive functioning, psychological issues, sexuality and comorbidity more than 2 years after commencing immune checkpoint inhibitor treatment

BACKGROUND

Increasing numbers of patients diagnosed with advanced cancer survive long-term after treatment with immune checkpoint inhibitors (ICIs). To design adequate interventions for these survivors, knowledge regarding quality of life (QOL) and its association with long-term and late effects of ICI treatment is required. Therefore, this study aimed to evaluate QOL, neurocognitive function, psychological issues, sexuality, and comorbidities in patients surviving at least 2 years after commencing ICI treatment.

METHODS

We performed a cross-sectional study in patients with stage III-IV melanoma, non-small cell lung cancer (NSCLC), urothelial cell carcinoma (UCC), or renal cell carcinoma (RCC) who survived at least 2 years after the start of ICIs. We assessed QOL, neurocognitive function, psychological issues, sexual function and comorbidity in survivors. Additionally, we evaluated QOL of informal caregivers.

RESULTS

132 survivors (70 melanoma, 50 NSCLC, 12 UCC or RCC) and 80 caregivers were included. Median age was 65 years (range 30-85) and 50 survivors were women (38%). Median time since start and cessation of ICI treatment was 33 (range 21-91) and 18 (range 0-68) months, respectively. Average survivor QOL was comparable to the reference population, but 37 (28%) survivors had poor QOL. Depression and anxiety were negatively correlated with all QOL domains. Although immune-related adverse events were common, there was no association with lower QOL. Caregiver and survivor QOL were only weakly related. Neurocognitive concerns and formally tested neurocognitive impairment were present in 22 (17%) and 13 (15%) survivors, respectively, and were not associated with a diagnosis of brain metastases. Men had a high prevalence of erectile dysfunction and low sexual satisfaction. Half of the survivors met the criteria for the metabolic syndrome.

CONCLUSIONS

At least 2 years after the start of ICI treatment, one-quarter of cancer survivors had a clinically relevant lower QOL. This was associated with symptoms of depression and anxiety, but not with immune-related adverse events. Sexual issues and metabolic syndrome are prevalent. Survivorship care should address these issues in this population.

Screening for cognitive impairment in routine clinical oncology practice: a pilot study using patient-reported outcome measures and online cognitive testing in melanoma and breast cancer patients

PURPOSE

This pilot study aimed to identify patients with cognitive impairment by a stepped-care use of patient-reported outcome measures (PROMs) and complementary online cognitive tests implemented in routine clinical practice.

METHODS

Self-reported cognitive functioning was measured in breast cancer or melanoma patients, 6 months after start of treatment, with two items of the EORTC QLQ-C30. Scores below a predefined threshold of 75 indicated clinically relevant cognitive impairment. Subsequent objective cognitive functioning was assessed with an online test battery, consisting of seven tests. Impaired cognitive functioning was defined as a z score of ≤  - 1.5 on 2 or more tests, a z score of ≤  - 2 on one single test, or both. Descriptive statistics were used to analyze the prevalence of impairment.

RESULTS

In total, 261 patients completed PROMs 6 months after start treatment; 38/154 (25%) melanoma and 43/107 (40%) breast cancer patients reported clinically relevant self-reported cognitive impairment. Of them, 12/38 (32%) melanoma and 15/43 (35%) breast cancer patients opted for complementary online cognitive testing. Of those completing formal tests, objectively measured cognitive impairment was identified in 4/12 (33%) melanoma and 10/15 (67%) breast cancer patients.

CONCLUSION

A significant number of patients report cognitive problems 6 months after starting treatment. Only onethird was able and/or expressed the need for further diagnostics. Among those who were formally tested, 33-67% had cognitive impairment, which is 3-9% of the total group that completed PROMs in routine care.

IMPLICATIONS FOR CANCER SURVIVORS

This pilot study suggests that a stepped care pathway for cognitive problems is relevant and also mangable in terms of clinical care.

Immune checkpoint inhibitors and cancer-related cognitive decline: a propensity score matched analysis in active chemotherapy patients

Background

We investigated whether 1-year trajectories of cancer-related cognitive decline (CRCD) would be different in patients with chemotherapy combined with immune checkpoint inhibitors (chemoICI group) as compared with chemotherapy alone (chemo group).

Methods

Participants scheduled with or without ICI were prospectively recruited from three academic hospitals and followed up for 1 year in four sessions. Subjective and objective CRCD were measured by Perceived Cognitive Impairment (PCI) and Montreal Cognitive Assessment (MoCA), respectively. Primary endpoints were MoCA and PCI score changes and minimal clinically important difference (MCID), which was defined as threshold for meaningful impairment events. Propensity score matching (PSM) was performed for group comparison using logistic regression with covariates including age, cancer stage, and baseline cognitive scores. Linear mixed models adjusted for repeated measures.

Results

Out of 1557 recruited patients PSM yielded 460 patient pairs (1:1). Mean PCI and MoCA scores of both groups reached MCID at 12-month session in both groups. In chemoICI, MoCA score changes were significantly lower in the 12-month session, and PCI score changes were lower in the 6, 9, and 12-month sessions than chemo (P<0.05). One-year meaningful impairment events risks were 0.44 and 0.56 in chemoICI, significantly higher than that of chemo (0.35 and 0.38, P<0.01). Significant differences were found in mean event-free survival time in patients with and without irAE in chemoICI subgroup analysis.

Conclusions

Our findings suggest that combining chemotherapy with ICIs may exacerbate CRCD compared to chemotherapy alone. However, reliance on screening tools and self-reported measures limits definitive conclusions. Future studies incorporating comprehensive neuropsychological assessments are warranted. This study underscores the importance of using comprehensive cognitive assessments in future research to better understand the impact of ICIs on cognitive function.

A Systematic Review of Trajectories of Clinically Relevant Distress Amongst Adults with Cancer: Course and Predictors

To improve interventions for people with cancer who experience clinically relevant distress, it is important to understand how distress evolves over time and why. This review synthesizes the literature on trajectories of distress in adult patients with cancer. Databases were searched for longitudinal studies using a validated clinical tool to group patients into distress trajectories. Twelve studies were identified reporting trajectories of depression, anxiety, adjustment disorder or post-traumatic stress disorder. Heterogeneity between studies was high, including the timing of baseline assessments and follow-up intervals. Up to 1 in 5 people experienced persistent depression or anxiety. Eight studies examined predictors of trajectories; the most consistent predictor was physical symptoms or functioning. Due to study methodology and heterogeneity, limited conclusions could be drawn about why distress is maintained or emerges for some patients. Future research should use valid clinical measures and assess theoretically driven predictors amendable to interventions.

Exploring the Impact of the Multimodal CAPABLE eHealth Intervention on Health-Related Quality of Life in Patients With Melanoma Undergoing Immune-Checkpoint Inhibition: Prospective Pilot Study

Background

Patients with melanoma receiving immunotherapy with immune-checkpoint inhibitors often experience immune-related adverse events, cancer-related fatigue, and emotional distress, affecting health-related quality of life (HRQoL) and clinical outcome to immunotherapy. eHealth tools can aid patients with cancer in addressing issues, such as adverse events and psychosocial well-being, from various perspectives.

Objective

This study aimed to explore the effect of the Cancer Patients Better Life Experience (CAPABLE) system, accessed through a mobile app, on HRQoL compared with a matched historical control group receiving standard care. CAPABLE is an extensively tested eHealth app, including educational material, remote symptom monitoring, and well-being interventions.

Methods

This prospective pilot study compared an exploratory cohort that received the CAPABLE smartphone app and a multisensory smartwatch for 6 months (intervention) to a 2:1 individually matched historical prospective control group. HRQoL data were measured with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 at baseline (T0), 3 months (T1), and 6 months (T2) after start of treatment. Mixed effects linear regression models were used to compare HRQoL between the 2 groups over time.

Results

From the 59 eligible patients for the CAPABLE intervention, 31 (53%) signed informed consent to participate. Baseline HRQoL was on average 10 points higher in the intervention group compared with controls, although equally matched on baseline and clinical characteristics. When correcting for sex, age, disease stage, and baseline scores, an adjusted difference in fatigue of -5.09 (95% CI -15.20 to 5.02, P=.32) at month 3 was found. No significant nor clinically relevant adjusted differences on other HRQoL domains over time were found. However, information satisfaction was significantly higher in the CAPABLE group (β=8.71, 95% CI 1.54-15.88, P=.02).

Conclusions

The intervention showed a limited effect on HRQoL, although there was a small improvement in fatigue at 3 months, as well as information satisfaction. When aiming at personalized patient and survivorship care, further optimization and prospective investigation of eHealth tools is warranted.

Neurological complications in oncology and their monitoring and management in clinical practice: a narrative review

IMPORTANCE

New anti-tumor treatments, such as immune checkpoint inhibitors and CAR T-cell therapy, are associated with an increasing number of neurological issues linked to tumors not arising from nervous system such as neurological and neuropsychological side effects that can significantly impair quality of life in the short or long term. The science of pathomechanisms, therapeutic approaches, and preventive measures is still in its early stages, and the progress is hampered by the lack of studied connection between neurological and oncological disciplines.

OBJECTIVES

This work aimed to provide an overview of the questions raised in the field of clinical neuroscience that concern the outcomes of oncological diseases and their treatment. Furthermore, we give an outline of how a collaborative approach between neurology and oncology, with the implementation of neuroscience techniques including up-to-date diagnostics and therapy, can help to improve the quality of oncological patients' lives.

EVIDENCE REVIEW

The covered areas of investigation in the evaluated articles primarily encompassed the review of known neurological complications of oncological diseases caused by neurotoxic mechanisms of performed therapies or those linked to concurrent pathological conditions. Similarly, the methods of their diagnostics were assessed.

FINDINGS

Our literature review of 65 articles, including clinical trials, cohort studies, reviews, and theoretically based in vitro studies published between 1998 and 2023, outlines the broad spectrum of neurological complications primarily associated with malignant diseases and the anti-tumor therapies employed. Notably, immune-mediated complications, whose incidence is increasing due to the expanding use of new immunotherapies, require early detection and targeted treatment to prevent severe progression. In this context, neurological complications mediated by immune checkpoint inhibitors are often associated with significant impairments and high mortality, necessitating specialist consultation for early detection and differentiation from other phenotypically similar syndromes. Current data on the pathophysiology of these neurological complications are not reliable due to the limited number of studies. Moreover, there is a lack of evidence regarding the appropriate oncological approach in the event of therapy-related complications. Initial study results suggest that the establishment of interdisciplinary treatment interfaces for the management of oncology patients could improve the safety of these therapies and enhance the patients' quality of life.

CONCLUSIONS AND RELEVANCE

The accumulated knowledge on neurotoxicity caused by oncological diseases shows that the challenges in diagnosing and managing this condition are expanding in tandem with the growing array of therapies being employed. Therefore, it requires interdisciplinary approach with the introduction of new facilities enabling more personalized patient care.

Cognitive Symptoms Across Diverse Cancers

Importance

Psychosocial health services for adults with cancer should include support for cognitive symptoms and symptom clusters.

Objective

To characterize the frequency and severity of cognitive symptoms and to identify demographic and clinical risk factors associated with moderate to severe cognitive symptoms among outpatient adults with cancer seeking psychosocial support.

Design, Setting, and Participants

This cross-sectional study analyzed data from routine patient-reported symptom screening during clinic appointments at the Princess Margaret Cancer Centre in Toronto, Canada, between January 1, 2013, and December 31, 2019. Participants were outpatient adults (aged ≥18 years) with diverse cancer diagnoses who endorsed interest in receiving psychosocial support from a health care team member. Data analysis was performed from April 2020 to June 2024.

Main Outcomes and Measures

The presence and severity of cognitive symptoms as self-rated by participants were characterized across 12 cancer types: brain or central nervous system (CNS), breast, gastrointestinal, head and neck, gynecological, thyroid, lung and bronchus, sarcoma, genitourinary, melanoma, hematological, and all other cancers. Multivariable logistic regression was used to explore the associations between demographic, clinical, and symptom factors and moderate to severe cognitive symptoms.

Results

Across the sample of 5078 respondents (2820 females [55.5%]; mean [SD] age at time of survey, 56.0 [14.1] years) requesting psychosocial support, 3480 (68.5%) reported cognitive symptoms of any severity, ranging from 59.5% in sarcoma to 86.5% in brain or CNS cancer. Moderate to severe cognitive symptoms were reported by 1544 patients (30.4%), with the proportions being 51.3% for patients with brain or CNS, 37.0% for breast, 36.2% for thyroid, 30.9% for melanoma, 29.6% for head and neck, 28.3% for gastrointestinal, 28.2% for hematological, 28.1% for gynecological, 24.9% for lung and bronchus, 24.9% for sarcoma, 21.0% for genitourinary, and 26.8% for all other cancers. Across the entire sample, moderate to severe cognitive symptoms were associated with recurrence or progression involving the CNS (odds ratio [OR], 2.62; 95% CI, 1.80-3.81), depression (OR, 1.92; 95% CI, 1.59-2.31), tiredness (OR, 1.82; 95% CI, 1.52-2.19), drowsiness (OR, 1.64; 95% CI, 1.39-1.93), anxiety (OR, 1.57; 95% CI, 1.30-1.89), shortness of breath (OR, 1.38; 95% CI, 1.16-1.61), female sex (OR, 1.33; 95% CI, 1.14-1.56), first-line chemotherapy received (OR, 1.22; 95% CI, 1.05-1.41), and metastatic disease at diagnosis (OR, 0.74; 95% CI, 0.61-0.89). Within individual cancer types, tiredness and depression were consistently associated with moderate to severe cognitive symptoms.

Conclusions and Relevance

This cross-sectional study found that cognitive symptoms were frequently reported by patients across a wide range of cancer types; higher severity of cognitive symptoms was consistently associated with higher symptom burden. The findings could be used to inform decision-making regarding access to cognitive screening, assessment, and supportive care in outpatient oncology clinics.

Immune Checkpoint Inhibition-related Neuroinflammation Disrupts Cognitive Function

Combinatorial blockade of Cytotoxic T-lymphocyte associated protein 4 (CTLA-4) and Programmed Cell Death Protein 1 (PD-1) significantly improve the progression-free survival of individuals with metastatic cancers, including melanoma. In addition to unleashing anti-tumor immunity, combination immune checkpoint inhibition (ICI) disrupts immune-regulatory networks critical for maintaining homeostasis in various tissues, including the central nervous system (CNS). Although ICI- and cancer-related cognitive impairments (CRCI) in survivors are increasingly becoming evident, our understanding of ICI-induced immune-related adverse effects (IREA) in the CNS remains incomplete. Here, our murine melanoma model reveals that combination ICI impairs hippocampal-dependent learning and memory, as well as memory consolidation processes. Mechanistically, combination ICI disrupted synaptic integrity, and neuronal plasticity, reduced myelin, and further predisposed CNS for exaggerated experimental autoimmune encephalomyelitis. Combination ICI substantially altered both lymphoid and myeloid cells in the CNS. Neurogenesis was unaffected, however, microglial activation persisted for two-months post- ICI, concurrently with cognitive deficits, which parallels clinical observations in survivors. Overall, our results demonstrate that blockade of CTLA-4 and PD-1 alters neuro-immune homeostasis and activates microglia, promoting long-term neurodegeneration and driving cognitive impairments. Therefore, limiting microglial activation is a potential avenue to mitigate CNS IRAE while maintaining the therapeutic benefits of rapidly evolving ICIs and their combinations.

SIGNIFICANCE

Despite the superior therapeutic efficacy of immune checkpoint inhibition (ICI) for cancers, its undesired effects on brain function are not fully understood. Here, we demonstrate that combination ICI elevates neuroinflammation, activates microglia, leading to detrimental neurodegenerative and neurocognitive sequelae.

Prevalence and odds of anxiety and depression in cutaneous malignant melanoma: a proportional meta-analysis and regression

BACKGROUND

The psychological burden of cutaneous malignant melanoma (CM) is all-encompassing, affecting treatment adherence, recurrence and mortality. However, the prevalence and risk factors of anxiety and depression in CM remain unclear.

OBJECTIVES

To establish a benchmark pooled prevalence of anxiety and depression in CM, to provide magnitudes of association for clinical, therapeutic and demographic correlates, and to elucidate temporal trends in anxiety and depression from the time of diagnosis.

METHODS

This review followed the MOOSE guidelines. MEDLINE, Embase, PsychINFO, Web of Science and the Cochrane Library were queried from database inception to 24 August 2023. Study selection, data extraction and quality assessment were performed by two independent authors, utilizing both the Joanna Briggs Institute (JBI) and National Institutes of Health risk-of-bias tools for the latter. The GRADE approach was used to rate the certainty of evidence. Prevalence rates, 95% confidence intervals (CIs) and prediction intervals (PIs) were derived using a random-effects model and estimating between- and within-study variance.

RESULTS

Nine longitudinal and 29 cross-sectional studies were included (7995 patients). Based on the JBI and NIH tools, respectively, quality assessment found 20 and 17 to be at low risk of bias, 12 and 15 to be at moderate risk and 6 and 5 to be at high risk of bias. The prevalence of anxiety [30.6% (95% CI 24.6-37.0; PI 18-47%)] and depression [18.4% (95% CI 13.4-23.9; PI 10-33%)] peaked during treatment, declining to pretreatment levels after 1 year [anxiety: 48% vs. 20% (P = 0.005); depression: 28% vs. 13% (P = 0.03)]. Female sex [odds ratio (OR) 1.8, 95% CI 1.4-2.3; P < 0.001], age < 60 years (OR 1.5, 95% CI 1.2-2.0; P = 0.002) and low educational level (OR 1.5, 95% CI 1.2-2.0; P < 0.001) were likely to result in a large increase in the odds of anxiety. Depression was 12.3% higher in those with stage IV vs. those with stage I CM (P = 0.05). Relative to immune checkpoint inhibition, the rates of depression were 22% (P = 0.002) and 34% (P < 0.001) higher among patients with advanced-stage CM receiving interferon-α and chemotherapy, respectively. A significant reduction in self-reported depression scores was demonstrated over time (P = 0.003).

CONCLUSIONS

Notably, anxiety and depression in CM affect women, those younger than 60 years of age and the less educated, with up to 80% higher odds of anxiety in these groups. Anxiety and depression surge during chemotherapy and interferon treatment, especially in advanced CM. Our findings facilitate risk stratification and underscore the need for multidisciplinary vigilance.

From decision to reflection: understanding the experiences and unmet care needs of patients treated with immunotherapy for melanoma in the adjuvant or metastatic setting

BACKGROUND

Despite increased use of immune checkpoint inhibitors (ICIs) in patients with advanced melanoma, little is known about patient experiences during this treatment. This study aimed to gain an in-depth understanding of experiences and unmet care needs of patients treated in the adjuvant or metastatic setting for advanced melanoma regarding their ICI treatment trajectory.

METHODS

Interviews and focus groups were conducted among 35 patients treated with ICIs in the adjuvant setting for completely resected stage III (n = 14), or in the metastatic setting for irresectable stage IV (n = 21) melanoma. A thorough thematic content analysis was conducted.

RESULTS

Three main themes were identified. When (1) dealing with uncertainty in the decision-making process, adjuvant patients explored the pros and cons, whereas metastatic patients considered immunotherapy their only viable option. Both groups expressed the need for additional guidance. In (2) navigating the immunotherapy course, both perceived the trajectory as intense, experienced a major impact on their and their (close) relatives' lives, and felt the need to (re)gain control. When (3) looking back on the immunotherapy experience, metastatic patients generally felt relieved, while among adjuvant patients, feelings of doubt regarding their choice for ICIs were also reported.

CONCLUSIONS

ICI treatment is perceived as intensive for both patient groups, facing both comparable and distinct challenges throughout the treatment trajectory, underscoring the need for stage-specific, individualised guidance. Options regarding flexible follow-ups, low-threshold contact and psychosocial support throughout the treatment trajectory should be explored.

Health-related quality of life and neurocognitive functioning in patients with recurrent glioblastoma treated with intracerebral immune checkpoint inhibition

PURPOSE

After glioblastoma (GB) recurrence, prognosis is very cumbersome. Therefore, health-related quality of life (HRQoL) and neurocognitive functioning (NCF) have become important endpoints in clinical trials when evaluating novel treatments. We aimed to evaluate the HRQoL and NCF in patients with recurrent glioblastoma (rGB) treated with a combination of surgical intervention (reoperation or biopsy) and intracerebral immune checkpoint inhibition.

METHODS

Patients who participated in the trial (N = 23), at a single-center university hospital were included. Data were collected using 3 patient-reported outcome measures (EORTC-QLQ-C30, EORTC-QLQ-BN20, and HADS) and computerized NCF testing. In the responder group, baseline values were compared to results at a 6-month follow-up. Additionally, exploratory analyses compared baseline HRQoL and NCF between responders and non-responders.

RESULTS

There were five responders and 18 non-responders. When comparing the mean and individual baseline with follow-up results for the responders, we observed overall a stable to slight clinically relevant improvement of HRQoL in multiple subsets of the questionnaires while maintaining a stable NCF. One patient deteriorated on anxiety and depression symptoms from baseline to follow-up.

CONCLUSIONS

In patients that responded to intracerebral immunotherapy in our institutional trial, HRQoL and NCF remained stable over time, suggesting that no detrimental effect on cognitive function or quality of life may be expected with this treatment approach. Furthermore, there seems to be an overall tendency for responders to score better on HRQoL and NCF than non-responders at baseline.

Emotional Distress, Cognitive Complaints, and Care Needs among Advanced Cancer Survivors Treated with Immune Checkpoint Blockade: A Mixed-Method Study

BACKGROUND

There is a need for a better understanding of survivorship-related issues in advanced cancer survivors treated with immune checkpoint blockade (ICB). The purpose of this study was to identify survivorship-related issues, with a focus on psychological distress, cognitive complaints, physical sequelae, impact on family dynamics, and care needs in unresectable, advanced cancer survivors treated with ICB.

METHODS

Semi-structured interviews and patient-reported outcome measures (PROMs) were conducted in survivors followed up at the University Hospital Brussels. We performed content analysis on the semi-structured interviews and analyzed the PROMs descriptively.

RESULTS

70 cancer survivors (71.4%) consented to participate between July 2022 and November 2023. Clinical fear of cancer recurrence (FCR) was present in 54.3% of the cancer survivors, and 18.6% had elevated cognitive complaints. We identified triggers related to clinically important psychological distress, such as immune-related adverse events, the progression/recurrence of disease, difficulties in adjusting to life after treatment, and co-existing life stressors, alongside persistent physical issues and unmet psychological and nutritional care needs.

CONCLUSION

Our results indicate the existence of persistent psychological, physical, and cognitive issues, and support the need for routine screening for FCR. The identified triggers related to severe psychological distress can aid clinicians in timely referring the patient, thereby enhancing survivorship care.

The Symptom Experience of Patients with Advanced Melanoma Undergoing Immune Checkpoint Inhibitor (ICI) Therapy

OBJECTIVES

The advent of immune checkpoint inhibitor (ICI) therapy has vastly improved outcomes for patients with advanced melanoma. However, the symptom burden and intensity with their impact on quality-of-life (HRQoL) and functionality are heterogeneous and unpredictable. We used descriptive exploratory content analysis from interviews to capture the patient experience after they had completed quantitative data collection of their symptom burden and interference with the use of two patient-reported outcome (PRO) instruments.

DATA SOURCES

Participants from a single center with advanced melanoma (n = 19) who are undergoing ICI therapy completed the Modified MD Anderson Symptom Inventory and Functional Assessment of Cancer Therapy-Melanoma and recorded semistructured interviews. Interpretive description informed the inductive and iterative analysis approach.

CONCLUSION

Participants had a heterogenous experience of ICI and melanoma-related symptoms: distress (84%), fatigue (68%), rash or skin changes (53%), pain (30%), diarrhea (30%), itching (26%), and shortness of breath (21%), with varying interference within HRQoL domains, mood (47%), relations with other people (26%), and activity (21%). Some noted a lack of physical interference (79%). Uncertainty was a pervasive theme in the interviews (68%) despite the majority having positive thoughts about ICI therapy (58%) and expectations of the success of therapy (53%). The physical and emotional burden of a melanoma diagnosis, undergoing therapy, and the uncertainty of the outcomes are pervasive for patients.

IMPLICATIONS FOR NURSING PRACTICE

Communication surrounding the diagnosis, prognosis, treatment options, and outcomes need to be clear and acknowledge there are unknowns. Nurses may benefit from using a validated PRO instrument to help document and understand the patient's symptom experience while undergoing ICI therapy.

Impact of Immune Checkpoint Inhibitor Therapy on Quality of Life in Patients With Advanced Melanoma: A Systematic Review

BACKGROUND

Immune checkpoint inhibitors (ICIs) were approved to treat advanced melanoma (AM) because of meaningful clinical benefit. These early data reported that ICI therapy is generally well tolerated, and despite symptoms, patients reported a high global health-related quality of life (HRQOL).

OBJECTIVE

Immune checkpoint inhibitors are widely used in the oncology community; the aim of this systematic review was to evaluate current data on ICI therapy and its impact on HRQOL of patients with AM.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed during this systematic review to identify and select studies from the PubMed, OVID, EMBASE, and Cochrane databases. Selected studies were downloaded into Covidence and analyzed for trends in how ICI therapy impacts HRQOL in patients with AM. Multiple tools were used to assess the quality of the studies.

RESULTS

The 16 studies included 12 quantitative, 2 qualitative, and 2 mixed-methods studies. The quality of the studies was moderate (n = 7) or strong (n = 9). Symptoms that impacted HRQOL were fatigue, endocrine dysfunction, rash, diarrhea, cognitive impairment, emotional impact (anxiety and depression), and financial toxicity. Suicidal ideation and 1 attempt were reported in 2 studies, which had not been previously published.

CONCLUSION

Patient-reported symptoms due to ICI negatively impacted HRQOL. Anxiety and depression are prevalent. Current QOL instruments do not capture the entire patient experience.

IMPLICATIONS FOR PRACTICE

Patients need to be asked if their symptoms are impacting their HRQOL. Further prospective research is needed to develop or adjust current patient-reported outcome instruments to adequately capture the impact of ICIs on HRQOL.

Real-World Effectiveness, Safety, and Health-Related Quality of Life in Patients Receiving Adjuvant Nivolumab for Melanoma in Belgium and Luxembourg: Results of PRESERV MEL

BACKGROUND

Nivolumab, an anti-programmed cell death 1 immuno-oncology therapy, is approved as an adjuvant treatment for patients with completely resected stage III or stage IV melanoma. PRESERV MEL (Prospective and REtrospective Study of nivolumab thERapy in adjuVant MELanoma) is a real-world observational study evaluating the effectiveness and safety of adjuvant nivolumab in patients with completely resected stage III or stage IV melanoma in clinical practice in Belgium and Luxembourg.

METHODS

Patients were enrolled prospectively and retrospectively during a 2-year period (January 2019-January 2021), and will be followed for 5 years. The results reported here are for the second interim analysis (cutoff date 31 December 2021). The index date was the date of first administration of adjuvant nivolumab. Patients received nivolumab for up to 12 months per label. Outcomes included relapse-free survival (RFS), adverse events (AEs)/treatment-related AEs (TRAEs), and health-related quality of life (HRQoL; assessed in prospectively enrolled patients using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30), Functional Assessment of Cancer Therapy-Melanoma (FACT-M), and EQ-5D-3L instruments). HRQoL was evaluated at group level (mean change in scores from baseline based on minimally important differences) and individual patient level (percentage of patients with clinically important scores based on threshold of clinical importance). Outcomes were analyzed descriptively.

RESULTS

The study enrolled 152 patients (125 prospective, 27 retrospective) at 15 hospitals in Belgium and Luxembourg. Minimum potential follow-up at time of analysis was 11.4 months. Median age was 60 years (range 29-85), and 53% of patients were male. At 12 and 18 months, the RFS rates were 74.7% (95% confidence interval (CI): 66.9-80.9) and 68.4% (95% CI: 60.0-75.5), respectively. Median RFS was not reached. Grade 3 or 4 TRAEs were reported in 14% of patients. AEs led to treatment discontinuation in 23% of patients. Deaths occurred in 3% of patients and were not related to treatment. Questionnaire completion rates for HRQoL were high at baseline (90-94%) and at 24 months (78-81%). In the group-level analysis for HRQoL, mean changes in scores from baseline remained stable and did not exceed prespecified thresholds for minimally important differences during and after treatment, except for a clinically meaningful improvement in FACT-M surgery subscale scores. In the individual patient-level analysis for EORTC QLQ-C30 subscales, the percentages of patients who reported clinically relevant scores for fatigue and cognitive impairment increased during treatment (at 9 months) compared with baseline. After treatment cessation (at 18 months), the percentage of patients who reported clinically relevant scores for fatigue decreased. However, the percentages of patients who reported clinically relevant scores for emotional, cognitive, and social impairment increased at 18 months compared with during treatment. Most patients with emotional impairment at 9 and 18 months did not experience disease recurrence (91% and 89%, respectively).

CONCLUSIONS

These results confirm the real-world effectiveness and safety of nivolumab as an adjuvant treatment for patients with completely resected stage III or stage IV melanoma. Cancer-specific, disease-specific, and generic HRQoL were maintained during and after treatment. The percentage of patients reporting emotional and cognitive impairment increased after treatment cessation, emphasizing the need for further investigation and tailored supportive care in these patients.

Health-state utilities in long-term advanced melanoma survivors comparable with the general population

BACKGROUND

Checkpoint inhibitors have been shown to substantially improve the survival of patients with advanced melanoma. With this growing group of survivors treated with immunotherapies, assessing their health-state utilities is essential and can be used for the calculation of quality-adjusted life years and for cost-effectiveness analyses. Therefore, we evaluated the health-state utilities in long-term advanced melanoma survivors.

METHODS

Health-state utilities were evaluated in a cohort of advanced melanoma survivors 24-36 months (N = 37) and 36-plus months (N = 47) post-ipilimumab monotherapy. In addition, the health-state utilities of the 24-36 months survivor group were assessed longitudinally, and utilities of the combined survival groups (N = 84) were compared with a matched control population (N = 168). The EQ-5D was used to generate health-state utility values, and quality-of-life questionnaires were used to establish correlations and influencing factors of utility scores.

RESULTS

Health-state utility scores were similar between the 24-36 months'- and the 36-plus months' survival group (0.81 vs 0.86; p = .22). In survivors, lower utility scores were associated with symptoms of depression (β = - .82, p = .022) and fatigue burden (β = - .29, p = .007). Utility scores did not significantly change after 24-36 months of survival, and the utilities of survivors were comparable to the matched control population (0.84 vs 0.87; p = .07).

DISCUSSION

Our results show that long-term advanced melanoma survivors treated with ipilimumab monotherapy experience relatively stable and high health-state utility scores.

Psychological and behavioral symptoms in patients with melanoma: A systematic review and meta-analysis

OBJECTIVE

Improved survival rates have made it increasingly important for clinicians to focus on cancer survivorship issues affecting the quality of life of melanoma patients. To provide a comprehensive overview of the disease and treatment-related issues affecting such patients, we conducted a systematic review and meta-analysis of the literature to estimate the prevalence of symptoms of depression, anxiety, fatigue, sleep disturbance, and cognitive problems among melanoma patients, both uveal and cutaneous, before, during and after treatment.

METHODS

The review was preregistered with PROSPERO (#CRD42020189847) and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of the literature published up until June 2022 was undertaken using PubMed, PsycInfo, the Cochrane Library, and CINAHL. Two independent reviewers screened 1418 records and quality-rated included studies. The reported prevalence rates of symptoms were pooled using a random-effects model.

RESULTS

Sixty-six studies including a total of 12,400 melanoma patients published between 1992 and 2022 were included. Pooled prevalence rates ranged from 6% to 16% for depression and 7%-30% for anxiety across diagnoses (uveal and cutaneous melanoma) and assessment time points. One third of the patients (35%) reported clinically significant fatigue, 20%-44% had cognitive complaints, while prevalence of sleep disturbance was not reported. Quality assessment indicated that 80% of the studies were of good quality.

CONCLUSION

A large body of research shows that depression and anxiety symptoms are prevalent in melanoma patients before, during and after treatment. However, research examining other symptoms known to affect quality of life, such as fatigue, sleep disturbances, and cognitive problems, is still needed.

A systematic review of patient-reported outcome measures for advanced skin cancer patients

Many patient-reported outcome measures (PROMs) have been used to study quality of life (QOL) in the skin cancer population. Advanced melanoma and non-melanoma skin cancer (NMSC) may be associated with increased morbidity, mortality, and treatment side effects; however, it is unclear which PROM is valid and appropriate to use in these populations for both clinical and research purposes. We aimed to identify the PROMs that have been used to measure QOL in advanced skin cancer patients and determine which of these PROMs have been validated to assess QOL outcomes in this population. A PubMed and EMBASE search was conducted from its inception to March 2021 according to PRISMA guidelines with a comprehensive list of search terms under three main topics: (1) PROM; (2) advanced skin cancer; and (3) staging and interventions. We included articles utilizing a PROM measuring QOL and having a patient population with advanced skin cancer defined as melanoma stage > T1a or non-melanoma AJCC stage T3 or greater. Advanced skin cancer patients were also defined as those with metastasis or requiring adjuvant therapy (systemic chemotherapy, radiation, and immunotherapy). Studies were excluded according to the following criteria: mix of low-risk and advanced skin cancer patients in the study population without stratification into low-risk and advanced groups, stage T1a melanoma or mix of stages without stratification, low-risk NMSC, no PROM (i.e., study specific questionnaires), non-English publication, review article or protocol paper, conference abstract, or populations including non-skin cancers. A total of 1,998 articles were identified. 82 met our inclusion criteria resulting in 22 PROMs: five generic health-related (QWB-SA, AQoL-8D, EQ-5D, SF-36, and PRISM), six general cancer (EORTC QLQ-C30, EORTC QLQ-C36, LASA, IOC, Rotterdam Symptom Checklist, and FACT-G), nine disease-focused or specialized (EORTC QLQ-H&N35, EORTC QLQ-MEL38, EORTC QLQ-BR23, Facial Disability Index, FACT-H&N, FACT-BRM, FACT-B, FACT-M, and scqolit), and two general dermatology (Skindex-16 and DLQI) PROMs. All PROMs have been generally validated except for EORTC QLQ-MEL38. Only two PROMs have been validated in the advanced melanoma population: FACT-M and EORTC QLQ-C36. No PROMS have been validated in the advanced NMSC population. The PROMs that were validated in the advanced melanoma population do not include QOL issues unique to advanced skin tumors such as odor, bleeding, itching, wound care burden, and public embarrassment. Breast cancer and head and neck cancer instruments were adapted but not validated for use in the advanced skin cancer population due to the lack of an adequate instrument for this population. This study highlights the need for PROM instrument validation or creation specifically geared toward the advanced skin cancer population. Future studies should aim to develop and validate a PROM to assess QOL in this population.

Risk factors for cognitive impairment in radically treated stage III NSCLC: Secondary findings of the NVALT-11 study

AIM

To identify risk factors for self-reported cognitive impairment in radically treated stage III non-small cell lung cancer (NSCLC).

METHODS

Cognitive functioning was assessed using the EORTC-QLQ-C30 at seven pre-specified time points in the phase III NVALT-11 trial (observation versus prophylactic cranial irradiation [PCI] in stage III NSCLC treated with chemo-radiotherapy±surgery). Cognition was analyzed as binary (impairment or not) and continuous outcome, respectively, using generalized estimating equation (GEE) before and after multiple imputation. A score <75 was defined as cognitive impairment. A mean difference by <10, 10-<20, ≥ 20 points was regarded as no, moderate, and large clinical effect, respectively. We categorized the cognitive impairment into four types based on changes over time: sustained, reversible, recurring, and alternating.

RESULTS

In the no-PCI arm, 43/84 [51.2%] reported cognitive impairment at least once, of which 31.4% were sustained, 25.7% reversible, 28.6% recurring, and 14.3% alternating. Results were similar in the PCI arm. Cognitive functioning at baseline was comparable in two arms and a score <75 was a significant risk factor with large effect for subsequent cognitive impairment (no-PCI: β = -22.30, p<0.001; PCI arm: β = -22.34, p<0.001; All: β = -23.47, p<0.001). Younger age (≤ 60y), squamous histology, and PCI were risk factors without clinical relevance (β > -10, p<0.05). Cognitive functioning declined over time (β = -0.26, p=0.001) except for patients with cognitive impairment at baseline (β=0.141, p=0.33).

CONCLUSION

Cognitive impairment is dynamic over time with four types. Baseline cognitive impairment (score <75) is the most important risk factor for subsequent cognitive impairment in stage III NSCLC. Note: This work has been partly reported as an oral presentation at the ESTRO 2021 meeting (OC-0176).

Cognitive impairment after cancer treatment: mechanisms, clinical characterization, and management

Cognitive impairment is a debilitating side effect experienced by patients with cancer treated with systemically administered anticancer therapies. With around 19.3 million new cases of cancer worldwide in 2020 and the five year survival rate growing from 50% in 1970 to 67% in 2013, an urgent need exists to understand enduring side effects with severe implications for quality of life. Whereas cognitive impairment associated with chemotherapy is recognized in patients with breast cancer, researchers have started to identify cognitive impairment associated with other treatments such as immune, endocrine, and targeted therapies only recently. The underlying mechanisms are diverse and therapy specific, so further evaluation is needed to develop effective therapeutic interventions. Drug and non-drug management strategies are emerging that target mechanistic pathways or the cognitive deficits themselves, but they need to be rigorously evaluated. Clinically, consistent use of objective diagnostic tools is necessary for accurate diagnosis and clinical characterization of cognitive impairment in patients treated with anticancer therapies. This should be supplemented with clinical guidelines that could be implemented in daily practice. This review summarizes the recent advances in the mechanisms, clinical characterization, and novel management strategies of cognitive impairment associated with treatment of non-central nervous system cancers.

First-Line Immunotherapy with Check-Point Inhibitors: Prospective Assessment of Cognitive Function

Approximately 40% of patients with cancer are eligible for check-point inhibitor (CPI) therapy. Little research has examined the potential cognitive impact of CPIs. First-line CPI therapy offers a unique research opportunity without chemotherapy-related confounders. The purpose of this prospective, observational pilot was to (1) demonstrate the feasibility of prospective recruitment, retention, and neurocognitive assessment for older adults receiving first-line CPI(s) and (2) provide preliminary evidence of changes in cognitive function associated with CPI(s). Patients receiving first-line CPI(s) (CPI Group) were assessed at baseline (n = 20) and 6 months (n = 13) for self-report of cognitive function and neurocognitive test performance. Results were compared to age-matched controls without cognitive impairment assessed annually by the Alzheimer's Disease Research Center (ADRC). Plasma biomarkers were measured at baseline and 6 months for the CPI Group. Estimated differences for CPI Group scores prior to initiating CPIs (baseline) trended to lower performance on the Montreal Cognitive Assessment-Blind (MOCA-Blind) test compared to the ADRC controls (p = 0.066). Controlling for age, the CPI Group's 6-months MOCA-Blind performance was lower than the ADRC control group's 12-months performance (p = 0.011). No significant differences in biomarkers were detected between baseline and 6 months, although significant correlations were noted for biomarker change and cognitive performance at 6 months. IFNγ, IL-1β, IL-2, FGF2, and VEGF were inversely associated with Craft Story Recall performance (p < 0.05), e.g., higher levels correlated with poorer memory performance. Higher IGF-1 and VEGF correlated with better letter-number sequencing and digit-span backwards performance, respectively. Unexpected inverse correlation was noted between IL-1α and Oral Trail-Making Test B completion time. CPI(s) may have a negative impact on some neurocognitive domains and warrant further investigation. A multi-site study design may be crucial to fully powering prospective investigation of the cognitive impact of CPIs. Establishment of a multi-site observational registry from collaborating cancer centers and ADRCs is recommended.

Impact of immune checkpoint inhibitors and targeted therapy on health-related quality of life of people with stage III and IV melanoma: a mixed-methods systematic review

BACKGROUND

Immune checkpoint inhibitors (ICI) and targeted therapies (TT) have significantly improved disease control and survival in people with stage III and IV cutaneous melanoma. Understanding the impact of therapy on health-related quality of life (HRQL) is vital for treatment decision-making and determining targets for supportive care intervention. We conducted a mixed-methods systematic review to synthesise the impact of ICIs and TT on all domains of HRQL in these populations.

METHODS

A systematic literature search was conducted in April 2022 on MEDLINE, PsycINFO, Embase and the Cochrane Central Register of Controlled Trials. Quantitative and qualitative data relevant to the review question were extracted and synthesised in tables according to setting (adjuvant versus metastatic), treatment type (ICI versus TT) and HRQL issue.

RESULTS

Twenty-eight papers describing 27 studies were included: 15 randomised controlled trials (RCTs), four cohort studies, four single arm cross-sectional studies, two qualitative studies, one case control study and one mixed-methods study. In four studies of people with resected stage III melanoma, adjuvant pembrolizumab and dabrafenib-trametinib did not clinically or statistically change HRQL compared to baseline. In 17 studies of people with unresectable stage III/IV melanoma, inconsistencies in the impact of ICI on symptoms, functioning and overall HRQL were noted across different study designs. TT was associated with improvements in symptoms, functioning and HRQL across six studies.

CONCLUSION

This review highlights the key physical, psychological and social issues experienced by people with stage III and IV melanoma treated with ICI and TT. Inconsistencies in the impact of ICI on HRQL were observed in different study designs. This highlights the need for treatment-specific patient-reported outcome measures for determining the impact of these therapies on HRQL and real-world data to inform treatment decision-making and appropriate supportive care interventions.

Persistent immune-related adverse events after cessation of checkpoint inhibitor therapy: Prevalence and impact on patients' health-related quality of life

BACKGROUND

Immune checkpoint inhibitors (ICIs) may induce persistent immune-related adverse events (irAEs). We investigated persistent irAEs and implications on patients' lives compared to non-ICI-induced autoimmune diseases (AIs).

METHODS

The multicentre, cross-sectional study comprised 200 patients with cancer ≥12 weeks after ICI cessation (ICI-patients) and 2705 patients with AIs (AI-patients), recruited in German outpatient clinics and support groups. The prevalence of persistent irAEs subdivided in long-term (12 weeks to <12 months) and chronic irAEs (≥12 months) since ICI discontinuation, health-related quality of life (HRQoL) using the EuroQol 5D-5L (EQ-Index/VAS score), and burden of autoimmune symptoms and respective therapies were assessed.

RESULTS

Long-term/chronic irAEs occurred in 51.9%/35.5% of outpatient ICI-patients, including arthralgia (16.7%/16.1%), myalgia (13.0%/14.0%), hypothyroidism (11.1%/10.8%), xerostomia (7.4%/8.6%), vitiligo (13.0%/7.5%) and hypophysitis (9.3%/7.5%). ICI-patients with long-term/chronic irAEs reported clinically significantly reduced HRQoL compared to ICI-patients without long-term/chronic irAEs (EQ-Index score: 0.767/0.752 versus 0.920/0.923, p < 0.001/0.001; EQ-VAS score: 52.2/52.0 versus 63.6/74.7, p =/< 0.040/0.001). Multiple linear regression analyses confirmed clinically significant reductions in HRQoL scores by chronic irAEs (EQ-Index/VAS score: -0.163/-23.4, p < 0.001/0.001). HRQoL, burden of autoimmune symptoms and burden of respective therapies in ICI-patients with chronic irAEs were similar to AI-patients with non-exacerbated AIs. Patients with chronic irAEs felt inadequately informed about side-effects compared to patients without chronic irAEs (p < 0.001).

CONCLUSION

Persistent irAEs impose a significant burden on patients after ICI cessation. Especially in early tumour stages, risk-benefit ratios must be carefully evaluated, and patients need to be informed about potential long-term sequelae.

Study of Antidepressant-Like Effects of Albiflorin and Paeoniflorin Through Metabolomics From the Perspective of Cancer-Related Depression

Mental health has become a new challenge in cancer treatment, with a high prevalence of depression in patients with cancer. Albiflorin (AF) and paeoniflorinn (PF) are isomers extracted from the root of Paeoniae Radix Alba (Baishao in Chinese), belonging to the monoterpene glycosides, and multiple studies have been conducted on their antidepression and anti-cancer effects. However, the effects of AF and PF on cancer-related depression are unclear. Therefore, the current study aims to investigate whether the two isomers are able to exert antidepressant-like effects and understand the underlying mechanisms in a rat model, established by combining irradiation with chronic restraint stress and solitary confinement. Our results demonstrate a significant regulation of AF and PF in the pharmacodynamic index, including the peripheral blood, organ index, behavioral traits, and HPA axis, relative to control rats. In serum and cerebral cortex metabonomics analysis, AF and PF showed a significantly restorative trend in abnormal biomarkers and regulating ether lipid metabolism, alanine, aspartate, glutamate metabolism, tryptophan metabolism, carnitine metabolism, arachidonic acid metabolism, arginine and proline metabolism pathway. Eight potential biomarkers were further screened by means of receiver operating characteristic (ROC) analysis. The data indicate that AF and PF could effectively ameliorate a depression-like state in the model rats, and the mechanism may be associated with the regulation of the neuroendocrine immune system and disrupted metabolic pathways. Further experiments are warranted to comprehensively evaluate the antidepressant effects of AF and PF in cancer-related depression. This study provides a better insight into the action mechanisms of antidepression of TCM, and provides a new perspective for the therapy of cancer-related depression.

Experiences of resuming life after immunotherapy and associated survivorship care needs: a qualitative study among patients with metastatic melanoma

Background

Immune checkpoint inhibitors (ICIs) have significantly improved the overall survival of patients with metastatic melanoma. It is unclear how the growing group of metastatic melanoma survivors resume their lives after treatment, and which needs they have regarding survivorship care (SSC).

Objectives

To gain an in‐depth understanding of metastatic melanoma survivors’ experiences of resuming life after ICIs and their associated SSC needs.

Methods

A qualitative study was conducted among 20 patients with metastatic melanoma in whom ICIs had been discontinued after ongoing tumour response. One focus group (n = 9) was held, which was complemented by 11 individual interviews. Purposive sampling was used to select a variable sample in terms of sex, age, time since discontinuation of ICIs, and perceived impact of the disease. A topic guide was used to structure the (group) interviews, which were transcribed verbatim and analysed in a thematic content analysis, using several phases of coding.

Results

In resuming life after ICIs, the prognosis switch often caused mixed feelings among patients, mainly because of the uncertainty about the future. Demands and expectations from self and others, persistent complaints and new problems in different life domains often make it challenging to proceed with life as it was prior to metastatic cancer. Patients indicated they needed to find a new balance, which included learning to cope with uncertainty and a changed perspective on life and close relationships. In terms of SSC needs, patients particularly stressed the need for more tailored patient information, available at one location. In addition, they emphasized the need to know who to turn to in case of questions and indicated the need for psychosocial support, also for their close relatives.

Conclusions

Metastatic melanoma survivors face various challenges in resuming life after ICIs and are left with several unmet SSC needs. Efforts should be focused on offering psychosocial supportive care in addition to medical care, from diagnosis onwards, taking into account the patient’s close relatives. A single point of contact and personalized survivorship care plan (SCP) could be of added value in guiding them through the patient journey, which is, given its multidisciplinary nature, particularly important in melanoma care.

What is already known about this topic?

Since the introduction of immune checkpoint inhibitors (ICIs) the overall survival of patients with metastatic melanoma has improved significantly, leading to a growing group of melanoma survivors.

Melanoma survivors may face various problems and challenges in resuming life after treatment, which may be associated with unmet survivorship care (SSC) needs.

An in‐depth understanding of their experiences with resuming life and the associated SSC needs is currently lacking.

What does this study add?

Metastatic melanoma survivors experience various challenges after immunotherapy, from the uncertain prognosis switch to the struggle of finding a new balance in life.

Besides negative aspects, such as complaints in different life domains, the patient journey is often accompanied by positive outcomes, for example a changed perspective on life.

They stress the need for tailored patient information and broader supportive care, also for their close relatives.

What are the clinical implications of this work?

In addition to medical care, efforts should be focused on offering psychosocial supportive care, including return‐to‐work issues, from diagnosis onwards, ideally taking into account the patient’s close relatives.

To guide them through the patient journey, a single point of contact and a personalized survivorship care plan (SCP) could be of added value.

The latter is particularly important in melanoma care, given its multidisciplinary nature.

With this qualitative study we provided an in‐depth understanding of metastatic melanoma survivors' experiences of resuming life after ICIs and their associated SSC needs. They face various challenges in resuming life and efforts should be focused on offering psychosocial supportive care, in addition to medical care, from diagnosis onwards, taking into account the patient's close relatives. A single point of contact and personalized survivorship care plan (SCP) could be of added value in guiding them through the patiënt journey which is, given its multidisciplinary nature, particularly important in melanoma care.

Psychiatric comorbidities in cancer survivors across tumor subtypes: A systematic review

BACKGROUND

Psychiatric disorders are common but underdiagnosed in cancer survivors. Research suggests that tumor type has an effect on the prevalence of clinically relevant depression, anxiety, comorbid anxiety-depression and posttraumatic stress disorder (PTSD).

AIM

To identify studies that examined the prevalence of clinically relevant levels of depression, anxiety, comorbid anxiety-depression and PTSD for patients with one or more tumor sites and compare those prevalences between cancer subtypes.

METHODS

Four databases (PubMed, PsycInfo, PubPsych and the Cochrane Database) were searched and resulted in a total of 2387 articles to be screened. To be included, a study must have investigated cancer-free and posttreatment survivors using tools to assess clinically relevant levels of the listed psychiatric comorbidities. All articles were screened by two authors with a third author reviewing debated articles.

RESULTS

Twenty-six studies on ten different tumor types fulfilled all inclusion criteria and were included in the review. The studies showed heterogeneity regarding the study characteristics, number of participants, time since diagnosis, and assessment tools. Generally, all four comorbidities show higher prevalences in cancer survivors than the general population. Brain tumor survivors were reported to have a relatively high prevalence of both depression and anxiety. Studies with melanoma survivors reported high prevalences of all four psychiatric comorbidities. Regarding comorbidities, a wide range in prevalence existed across the tumor types. Within one cancer site, the prevalence also varied considerably among the studies.

CONCLUSION

Psychiatric comorbidities are more frequent in cancer survivors than in the general population, as reflected by the prevalence of depression, anxiety, comorbid anxiety-depression and PTSD across all tumor subtypes. Developing generalized screening tools that examine psychological distress in cancer survivors up to at least ten years after diagnosis could help to understand and address the psychological burden of cancer survivors.

Patient-Centered Palliative Care for Patients With Advanced Lung Cancer

The evidence base demonstrating the benefits of an early focus on palliative care for patients with serious cancers, including advanced lung cancer, is substantial. Early involvement of specialty-trained palliative care clinicians in the care of patients with advanced lung cancer improves patient-reported outcomes, such as quality of life, and health care delivery, including hospice utilization. Since the time that many of these palliative care trials were conducted, the paradigm of cancer care for many cancers, including lung cancer, has changed dramatically. The majority of patients with advanced lung cancer are now treated with immune checkpoint inhibitors or targeted therapies, both of which have had a significant impact on patient's experience and outcomes. With this changing landscape of lung cancer therapeutics, patients are facing new and different challenges, including dealing with novel side effect profiles and coping with greater uncertainty regarding their prognosis. Patients who are living longer with their advanced cancer also struggle with how to address survivorship issues, such as sexual health and exercise, and decision making about end-of-life care. Although palliative care clinicians remain well-suited to address these care needs, they may need to learn new skills to support patients treated with novel therapies. Additionally, as the experience of patients with advanced lung cancer is becoming more varied and individualized, palliative care research interventions and clinical programs should also be delivered in a patient-centered manner to best meet patient's needs and improve their outcomes. Tailored and technology-based palliative care interventions are promising strategies for delivering patient-centered palliative care.

Cognitive adverse effects of chemotherapy and immunotherapy: are interventions within reach?

One in three people will be diagnosed with cancer during their lifetime. The community of cancer patients is growing, and several common cancers are becoming increasingly chronic; thus, cancer survivorship is an important part of health care. A large body of research indicates that cancer and cancer therapies are associated with cognitive impairment. This research has mainly concentrated on chemotherapy-associated cognitive impairment but, with the arrival of immunotherapies, the focus is expected to widen and the number of studies investigating the potential cognitive effects of these new therapies is rising. Meanwhile, patients with cognitive impairment and their healthcare providers are eagerly awaiting effective approaches to intervene against the cognitive effects of cancer treatment. In this Review, we take stock of the progress that has been made and discuss the steps that need to be taken to accelerate research into the biology underlying cognitive decline following chemotherapy and immunotherapy and to develop restorative and preventive interventions. We also provide recommendations to clinicians on how to best help patients who are currently experiencing cognitive impairment.

Perception of information to Swedish melanoma patients in routine clinical practice - a cross-sectional survey

Background

Comprehensible, relevant information empowers patients, allowing them to take an active part in their care. We aim to investigate how Swedish melanoma patients perceive information provided in routine clinical practice and explore the correlation between satisfaction with information, symptoms and functioning scales, and quality of life.

Methods

A cross-sectional study where EORTC QLQ-C30, EORTC QLQ-INFO25 and EQ-5D-3L questionnaires were sent to 1213 patients by post and 792 responded (65%).

Results

Only 0.5% reported that they wished to have received less information. The amount of information received and the satisfaction with that information was age-dependent, where older patients reported receiving less information than younger patients. Middle-aged patients were more satisfied with the information compared to both younger and older patients. The perception of having received sufficient information correlated negatively with anxiety. Higher satisfaction with the information also correlated positively with scores for functioning scales and negatively with degree of symptoms. No difference was perceived in information levels between disease stage apart from the scale “information about other services”, where patients with more severe disease reported receiving more information. Men and women reported equal satisfaction concerning the information received.

Conclusions

Patients lack sufficient information and age affects the perception of it. It is of utmost importance to tailor the information to suit the individual needs of a given patient, as satisfaction with the information received correlates with the patient’s well-being.

Feasibility, acceptability, and utility of a nurse-led survivorship program for people with metastatic melanoma (MELCARE)

PURPOSE

Immune checkpoint inhibitors (ICIs) and targeted therapy (TT) have improved the survival of people with metastatic melanoma. We assessed the feasibility, acceptability, and utility of a novel model of nurse-led, telehealth-delivered survivorship care (MELCARE) for this survivor group.

METHODS

People ≥ 18 years diagnosed with unresectable stage III or stage IV melanoma who were ≥ 6 months post initiation of ICI/TT with a radiological response suggestive of a long-term response to ICI/TT were recruited from a specialist melanoma centre in Australia. All participants received MELCARE, a nurse-led survivorship program involving two telehealth consultations 3 months apart, needs assessment using the Distress Thermometer (DT) and Problem List, and creation of a survivorship care plan. Feasibility, acceptability, and utility were assessed using rates of consent and study completion, time taken to complete each component of MELCARE, the Acceptability of Intervention Measure (AIM), and a customised utility survey.

RESULTS

31/54 (57%) people consented. Participants were male (21, 68%), with a median age of 67 (range: 46-82). Eleven (35%) were receiving/had received ipilimumab and nivolumab and 27 (87%) had ceased treatment. Feasibility was demonstrated with 97% completing MELCARE. Utility was demonstrated on a customised survey and supported by a reduction in the mean DT score (initial: 5.6, SD: 2.9; follow-up: 1.5, SD: 1.2). Acceptability was demonstrated on 3/4 AIM items.

CONCLUSION

MELCARE was feasible and acceptable with high levels of utility. However, the consent rate was 57% indicating some people do not require support. Future studies should consider MELCARE's optimal timing, resourcing, and cost-effectiveness.

Living with and beyond metastatic non-small cell lung cancer: the survivorship experience for people treated with immunotherapy or targeted therapy

PURPOSE

Immunotherapy (IT) and targeted therapy (TT) have improved survival for some patients with metastatic non-small cell lung cancer (NSCLC). Their lived experience is under-studied. We conducted a single centre, qualitative study to understand concerns and unmet needs amongst this novel survivor population.

METHODS

Eligible participants had metastatic NSCLC, aged >18, English-speaking and >6 months post initiation of IT/TT without progressive disease. Semi-structured interviews focused on physical, psychological, social and functional impacts of diagnosis, therapy and prognosis. Interviews were recorded and transcribed. Data were analysed via qualitative thematic analysis.

RESULTS

Between May and December 2019, 20 participants were interviewed: median age 62 (range 34-83), 13 (65%) female; median time since diagnosis of metastatic NSCLC 27 months (range 10-108). Twelve out of 20 (60%) participants had a targetable mutation (EGFR/ALK/BRAF); 6 were receiving IT, 11 TT, 2 IT + chemotherapy and 1 IT + TT. Four main themes were identified: living long-term on IT and TT (chronic toxicities), psychological concerns (living with uncertainty, fear of cancer progression, scan-related anxiety), support with practical issues (finances, employment amidst prognostic uncertainty, challenges with trial participation) and wanting information pertinent to NSCLC subtype.

CONCLUSIONS

Longer-term survivors of metastatic NSCLC experience significant physical, psychological and functional concerns and unmet needs. Results will inform a broader cross-sectional survey and resources to address the needs of this growing survivor group.

IMPLICATIONS FOR CANCER SURVIVORS

A 'one-size-fits-all' approach to NSCLC survivorship is no longer appropriate. Survivors of metastatic NSCLC treated with novel therapies may benefit from specific information regarding long-term toxicities and psychological supports.

A Comprehensive Analysis of Baseline Clinical Characteristics and Biomarkers Associated with Outcome in Advanced Melanoma Patients Treated with Pembrolizumab

Simple Summary

Pembrolizumab, a monoclonal antibody targeting programmed cell death 1, improves the survival of patients with advanced melanoma. This study aimed to investigate the association of baseline clinical characteristics, laboratory and imaging variables, and gene expression profiling scores on tumor tissue analysis of advanced melanoma patients who were treated with pembrolizumab, with survival using univariate and multivariate analysis. Baseline organ function (reflected by the presence of active brain metastases, number of metastatically affected organs, albumin) and systemic inflammatory/immunologic status (reflected by albumin, C-reactive protein, absolute lymphocyte count, neutrophil-to-lymphocyte ratio) are the most important clinical and/or laboratory parameters predictive of survival. Novel biomarkers include the baseline presence of BRAF^V600 or NRAS^Q61/G12/G13 mutant circulating tumor DNA and baseline total metabolic tumor volume assessed by whole-body ¹⁸F-FDG-PET/CT. Gene expression profiling scores by the NanoString PanCancer IO360 panel were not conclusive in our patient population.

Abstract

Background: Pembrolizumab improves the survival of patients with advanced melanoma. A comprehensive analysis of baseline variables that predict the benefit of pembrolizumab monotherapy has not been conducted. Methods: Survival data of patients with advanced melanoma who were treated with pembrolizumab in a single university hospital were collected. A multivariate Cox regression analysis was performed to correlate baseline clinical, laboratory, and radiologic characteristics and NanoString IO360 gene expression profiling (GEP) with survival. Results: 183 patients were included (stage IV 85.2%, WHO performance status ≥1 31.1%; pembrolizumab first-line 25.7%), of whom 112 underwent baseline ¹⁸F-FDG-PET/CT imaging, 58 had circulating tumor DNA (ctDNA) assessments, and GEP was available in 27 patients. Active brain metastases, a higher number of metastatic sites, lower albumin and absolute lymphocyte count (ALC), higher C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio, higher total metabolic tumor volume (TMTV), and higher ctDNA levels were associated with worse survival. Elevated lactate dehydrogenase (LDH) ≥ 2ULN (upper limit of normal), CRP ≥ 10ULN, or ALC < 750/mm³ delineate a subpopulation where treatment with pembrolizumab is futile. A TMTV ≥ 80 mL encompassed 17/21 patients with LDH ≥ 2ULN, CRP ≥ 10ULN, or ALC < 750/mm³. No significant associations were observed between baseline GEP scores and survival. Conclusion: Multiple baseline variables correlate with survival on pembrolizumab. TMTV is a more comprehensive baseline biomarker than CRP, LDH, or ALC in predicting the futility of pembrolizumab.

Living with Metastatic Cancer: A Roadmap for Future Research

Living with metastatic cancer, or metavivorship, differs from cancer survivorship and has changed as novel treatments have increased survival time. The purpose of this narrative review is to describe factors that impact challenges in metavivorship within a conceptual framework to guide future research. This review focuses on the specific metavivorship outcomes of progressive disease, survival time, symptoms, distress, financial toxicity, and quality of life. We describe the predisposing, precipitating, and perpetuating (3P) model of metavivorship. Understanding the biological, psychological, and social 3P factors that contribute to the development and maintenance of challenges in metavivorship provides a roadmap for future research. Implications of this model include prevention by targeting predisposing factors, management of precipitating factors after onset of metastatic disease, and treatment of perpetuating factors to reduce symptoms and improve quality of life during the chronic phase of metavivorship. This can be accomplished through biopsychosocial screening efforts, monitoring of patient-reported outcomes, education and communication interventions, interdisciplinary symptom management, advance care planning, and behavioral interventions to cultivate psychological resilience.

Neurocognitive Function, Psychosocial Outcome, and Health-Related Quality of Life of the First-Generation Metastatic Melanoma Survivors Treated with Ipilimumab

Purpose

To assess neurocognitive function (NCF), psychosocial outcome, health-related quality of life (HRQoL), and long-term effects of immune-related adverse events (irAE) on metastatic melanoma survivors treated with ipilimumab (IPI).

Methods

Melanoma survivors were identified within two study populations (N = 104), at a single-center university hospital, and defined as patients who were disease-free for at least 2 years after initiating IPI. Data were collected using 4 patient-reported outcome measures, computerized NCF testing, and a semistructured interview at the start and 1-year follow-up.

Results

Out of 18 eligible survivors, 17 were recruited (5F/12M); median age is 57 years (range 33-86); and median time since initiating IPI was 5.6 years (range 2.1-9.3). The clinical interview revealed that survivors suffered from cancer-related emotional distress such as fear of recurrence (N = 8), existential problems (N = 2), survivor guilt (N = 2), and posttraumatic stress disorder (N = 6). The mean EORTC QLQ-C30 Global Score was not significantly different from the European mean of the healthy population. Nine survivors reported anxiety and/or depression (Hospitalization Depression Scale) during the survey. Seven survivors (41%) reported fatigue (Fatigue Severity Scale). Seven patients (41%) had impairment in NCF; only three out of seven survivors had impairment in subjective cognition (Cognitive Failure Questionnaire). Anxiety, depression, fatigue, and neurocognitive symptoms remained stable at the 1-year follow-up. All cases of skin toxicity (N = 8), hepatitis (N = 1), colitis (N = 3), and sarcoidosis (N = 1) resolved without impact on HRQoL. Three survivors experienced hypophysitis; all suffered from persistent fatigue and cognitive complaints 5 years after onset. One survivor who experienced a Guillain-Barré-like syndrome suffered from persisting depression, fatigue, and impairment in NCF.

Conclusion

A majority of melanoma survivors treated with IPI continue to suffer from emotional distress and impairment in NCF. Timely detection in order to offer tailored care is imperative, with special attention for survivors with a history of neuroendocrine or neurological irAE. The trial is registered with B.U.N. 143201421920.
