Cancer in older adults: understanding cause and effects of chemotherapy-related toxicities

Lived Experiences of Self-Care in Older Adults with Lymphoma Undergoing Chemotherapy Treatments During the COVID-19 Pandemic

Background: To be diagnosed and treated for cancer can be a distressing experience, and it can require individuals to engage in self-care strategies to cope with the situation. The self-care experiences of older adults with lymphoma undergoing chemotherapy during the COVID-19 pandemic in Thailand remain rarely studied. This study aimed to explore the lived experiences of self-care among older adults with lymphoma undergoing chemotherapy during the COVID-19 pandemic. Methods: A hermeneutic phenomenology research design was used. It involved in-depth interviews with nine older adults with lymphoma undergoing chemotherapy. Data analysis utilized van Manen's approach, and trustworthiness was ensured by adhering to Lincoln and Guba's criteria. Results: This study revealed that the lived experience of self-care among older adults with lymphoma receiving chemotherapy during the COVID-19 pandemic encompasses five lifeworlds within the lived body, addressing aspects of (1) thumjai and (2) continuing to fight cancer. Lived relations means trusting healthcare providers and holding on together. Lived time reflects being aware of the natural path of life. The concept of lived space encompasses staying safe at home and staying cautious. Lived things reflect (1) accepting one's own karma and (2) living economically. Conclusions: The findings enhance the understanding of self-care experiences among older adults with lymphoma undergoing chemotherapy during the COVID-19 pandemic in an Asian context. The findings can inform the development of a person-centered nursing intervention tailored for older persons that emphasizes cultural aspects.

Time toxicity in cancer care: A concept analysis using Walker and Avant's method

Objective

The purpose of this concept analysis was to explore and clarify the concept of time toxicity in the context of cancer care using Walker and Avant's method, identify its defining attributes, antecedents, and consequences, and explore its implications for cancer care.

Methods

Walker and Avant's eight-step method was employed to analyze time toxicity. The literature was reviewed, focusing on peer-reviewed articles, grey literature, and cancer care policy documents to identify the defining attributes, antecedents, consequences, and empirical referents of time toxicity. Contextual factors, such as health care infrastructure and socioeconomic status, shape the manifestation of time toxicity in different patient populations. Model, borderline, and contrary cases were developed to clarify the concept further.

Results

Time toxicity is characterized by its defining attributes of temporal burden, disruption of daily life, cumulative effect, opportunity cost, and emotional strain. Antecedents include cancer diagnosis, complex treatment regimens, and health care inefficiencies, while consequences involve reduced quality of life, non-adherence to treatment, and economic strain. Empirical referents include time logs, patient-reported outcomes, and health care utilization data.

Conclusions

Our findings underscore the multidimensional nature of time toxicity and its significant implications for cancer patients' well-being. Importantly, we highlight the vital role of oncology nurses in mitigating its effects through care coordination and patient support, thereby making our research directly applicable to clinical practice.

Developing a National Study That Integrates the Geriatric Assessment into the Care of Older Patients with Myeloid Malignancies

PURPOSE OF REVIEW

To highlight the priorities in geriatric assessment research in myeloid malignancies and discuss design considerations necessary to ensure research is patient-centric, generalizeable, and high quality.

RECENT FINDINGS

Older adults with myeloid malignancies including those who are perceived to have excellent performance status have multiple functional impairments. These impairments are associated with early mortality. Older adults have different functional trajectories through the course of treatment; this will be further investigated in our ongoing multicenter study. In a single-center study, we have demonstrated the use of geriatric assessment to guide treatment is feasible. Key priorities include designing a multicenter validation study to confirm the role of geriatric assessment in determining treatment tolerance and survival. Such a study should include core geriatric assessment measures and should enroll diverse patient population across various practices. Conducting such a study is necessary to advance patient care and trial design, and to open venues to conduct studies to confirm the role of geriatric assessment in treatment selection.

Serious Gaming for Chemotherapy-Induced Nausea and Vomiting in Older Adults With Cancer: Protocol for a Randomized Clinical Trial

BACKGROUND

Older adults are at high risk for toxicity due to cancer treatment and increased risk for adverse events related to chemotherapy-induced nausea and vomiting (CINV). Unfortunately, older adults report multiple treatment-related symptoms but use few strategies to self-manage these symptoms due to erroneous beliefs related to the effectiveness of commonly taught self-management strategies. We developed a novel serious game, Managing at Home (MAH), to help older adults learn how to effectively self-manage CINV at home.

OBJECTIVE

This study has 2 aims. Aim 1 is to examine changes in CINV severity, self-management behaviors, functioning, quality of life, cognitive representation, and health care use within the intervention group from baseline (T1) to completion of the study (T6). Aim 2 is to determine the efficacy of the MAH intervention by comparing differences in primary outcomes (CINV severity and health care use) and secondary outcomes (self-management behaviors, functioning, and quality of life) between the intervention and control groups at each follow-up visit (T2-T6) and completion of the study (T6).

METHODS

This is a longitudinal randomized clinical trial. We will collect data from 500 older adults receiving cancer-related chemotherapy at baseline (T1) and at each treatment cycle until cycle 6 (T6). Participants will be enrolled if they are 60 years or older of age, are newly diagnosed with cancer, being treated with any chemotherapy agent with moderate or high emetic potential, are on a 2-, 3-, or 4-week treatment cycle, are proficient in English, and have a telephone. Previous diagnosis or treatment for cancer, end-stage disease with less than 6 months to live, and uncorrected visual or hearing impairment are exclusion criteria.

RESULTS

This study was funded in September 2022 and received institutional review board approval in October 2022. As of July 2023, the enrollment of participants is ongoing and currently has 130 enrolled participants. Data collection and analysis will be complete in 2027.

CONCLUSIONS

This study addresses self-management of CINV in older adults using an innovative serious game. The MAH intervention uses simulation and gaming technology to engage older adults in active learning in order to reframe erroneous perceptions about symptom self-management. If shown to be effective, it can easily be adapted to include other cancer-related symptoms or other chronic illnesses.

Effectiveness of Artificial Intelligence Technologies in Cancer Treatment for Older Adults: A Systematic Review

Background: Aging is a multifaceted process that may lead to an increased risk of developing cancer. Artificial intelligence (AI) applications in clinical cancer research may optimize cancer treatments, improve patient care, and minimize risks, prompting AI to receive high levels of attention in clinical medicine. This systematic review aims to synthesize current articles about the effectiveness of artificial intelligence in cancer treatments for older adults. Methods: We conducted a systematic review by searching CINAHL, PsycINFO, and MEDLINE via EBSCO. We also conducted forward and backward hand searching for a comprehensive search. Eligible studies included a study population of older adults (60 and older) with cancer, used AI technology to treat cancer, and were published in a peer-reviewed journal in English. This study was registered on PROSPERO (CRD42024529270). Results: This systematic review identified seven articles focusing on lung, breast, and gastrointestinal cancers. They were predominantly conducted in the USA (42.9%), with others from India, China, and Germany. The measures of overall and progression-free survival, local control, and treatment plan concordance suggested that AI interventions were equally or less effective than standard care in treating older adult cancer patients. Conclusions: Despite promising initial findings, the utility of AI technologies in cancer treatment for older adults remains in its early stages, as further developments are necessary to enhance accuracy, consistency, and reliability for broader clinical use.

Anti-Angiogenic Tyrosine Kinase Inhibitor-Related Toxicities Among Cancer Patients: A Systematic Review and Meta-Analysis

BACKGROUND

Targeting of angiogenesis has become a major therapeutic approach for the treatment of various advanced cancers. There are many unresolved questions on the toxicity of anti-angiogenic tyrosine kinase inhibitors (TKIs).

OBJECTIVE

We performed a meta-analysis to assess the toxicity prevalence of the different anti-angiogenic TKIs among cancer patients and in subpopulations of interest including patients with renal cell carcinoma.

PATIENTS AND METHODS

We searched the MEDLINE and Cochrane Library databases to November 2023. Clinical trials were eligible if they set out to report the grade ≥3 toxicities related to one of the seven currently approved anti-angiogenic TKIs as monotherapies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was applied with PROSPERO (CRD42023411946).

RESULTS

The 421 eligible studies included a total of 56,895 cancer patients treated with anti-angiogenic TKI monotherapy. Twenty-four different cancer types were identified, mainly renal cell carcinoma (41.9% of the patients). The anti-angiogenic TKI was sorafenib (34.5% of the patients), sunitinib (30.5%), regorafenib (10.7%), pazopanib (9.4%), cabozantinib (7.7%), axitinib (4.3%), and lenvatinib (2.9%). The pooled prevalence of grade 3 and 4 toxicities was 56.1% (95% confidence interval 53.5-58.6), with marked between-study heterogeneity (I2 = 96.8%). Toxicity profiles varied considerably depending on the type of TKI, the cancer type, and the specific patient characteristics. In particular, Asian patients and elderly people had higher prevalences of severe toxicities, with pazopanib being the best-tolerated drug. For patients treated with sunitinib, particularly those with metastatic RCC, there was no significant difference in terms of toxicity according to the regimen schedule.

CONCLUSIONS

This meta-analysis highlights the toxicity profiles of anti-angiogenic TKI monotherapies, and thus enables high-level recommendations for the choice of anti-angiogenic TKIs on the basis of the patient's age, ethnicity, comorbidities, and comedications, for personalized treatment.

Subgroup analyses from the phase 3 ASCENT study of sacituzumab govitecan in metastatic triple-negative breast cancer

In this post hoc analysis of the ASCENT study, we compared outcomes with sacituzumab govitecan (SG) vs single-agent chemotherapy in clinically important subgroups of patients with metastatic triple-negative breast cancer (mTNBC). Patients with mTNBC refractory to/relapsing after ≥2 prior chemotherapies (≥1 in the metastatic setting) were randomized 1:1 to receive SG or treatment of physician's choice (TPC) until unacceptable toxicity/progression. The primary endpoint was progression-free survival (PFS) per RECIST 1.1 by central review in patients without brain metastases. Patients with brain metastases were allowed if metastases were stable ≥4 weeks. In the intention-to-treat (ITT) population, 19% of patients were age ≥65 years; 12% were Black, and 12% had brain metastases. SG improved PFS and overall survival (OS), respectively, vs TPC in patients age ≥65 years (7.1 vs 2.4 months and 14.7 vs 8.9 months), or of Black race (5.4 vs 2.2 months and 13.8 vs 8.5 months), consistent with outcomes in the ITT population. Patients with brain metastases had numerically higher median PFS with SG vs TPC, but median OS was similar between treatment groups. SG was well tolerated and had a manageable safety profile consistent with the full safety population across all subgroups; neutropenia and diarrhea were the most common treatment-emergent adverse events. These findings confirm the meaningful clinical benefit of SG vs standard chemotherapy in patient subgroups with high unmet needs. SG should be considered an effective and safe treatment option for patients with mTNBC eligible for second-line or later therapy. ClinicalTrials.gov Number: NCT02574455.

Estimating the Associated Burden of Illness and Healthcare Utilization of Newly Diagnosed Patients Aged ≥65 with Mantle Cell Lymphoma (MCL) in Ontario, Canada

BACKGROUND

With the emergence of therapies for mantle cell lymphoma (MCL), understanding the treatment patterns and burden of illness among older patients with MCL in Canada is essential to inform decision making.

METHODS

A retrospective study using administrative data matched individuals aged ≥65 who were newly diagnosed with MCL between 1 January 2013 and 31 December 2016 with general population controls. Cases were followed for up to 3 years in order to assess healthcare resource utilization (HCRU), healthcare costs, time to next treatment or death (TTNTD), and overall survival (OS); all were stratified according to first-line treatment.

RESULTS

This study matched 159 MCL patients to 636 controls. Direct healthcare costs were highest among MCL patients in the first year following diagnosis (Y1: CAD 77,555 ± 40,789), decreased subsequently (Y2: CAD 40,093 ± 28,720; Y3: CAD 36,059 ± 36,303), and were consistently higher than the costs for controls. The 3-year OS after MCL diagnosis was 68.6%, with patients receiving bendamustine + rituximab (BR) experiencing a significantly higher OS compared to patients treated with other regimens (72.4% vs. 55.6%, p = 0.041). Approximately 40.9% of MCL patients initiated a second-line therapy or died within 3 years.

CONCLUSION

Newly diagnosed MCL presents a substantial burden to the healthcare system, with almost half of all patients progressing to a second-line therapy or death within 3 years.

Resource Use and Costs Related to Hematological Complications of Chemotherapy: Cost of Illness Study Based on Data from Balkan Country with Recent History of Socioeconomic Transition

Background

The administration of chemotherapy positively correlates with diverse adverse drug reactions, including the significant impact of hematological hazards such as anemia, leukopenia-neutropenia, thrombocytopenia, and pancytopenia. This pilot pharmacoeconomic study aimed to estimate the total direct costs of treating hematological toxicity induced by chemotherapy and its main determinants.

Methods

The study was conducted as a retrospective cost of illness study using the "from bottom to the top" approach from the perspective of the Republic Health Insurance Fund. This study included 88 patients treated due to developing at least one episode of one of the types of hematological complications of cytostatics in 2018 at the Oncology Clinic of the University Clinical Center Kragujevac, Kragujevac, the Republic of Serbia.

Results

Among cancer patients who developed haematological toxicity, treating pancytopenia was most demanding in a pharmacoeconomic manner compared to neutropenia and thrombocytopenia, with an estimated value of direct costs of 264,14, 178,19 and 157,76 euros per patient per year respectively. Regarding total direct costs, the main determinants were the costs of drugs, their parenteral administration, and costs due to hospitalization.

Conclusion

Due to the rising cancer incidence and obligatory hospital treatment of hematological toxicity induced by chemotherapy, the identification of the pharmacoeconomic aspects of the treatment of these complications is needed. Future research should focus on the development of new modalities of treatment regarding patient characteristics anticipating high costs.

Tolerance to oral anticancer agent treatment in older adults with cancer: a secondary analysis of data from electronic health records and a pilot study of patient-reported outcomes

Background

More than 60% of cancer cases occur in older adults, and many are treated with oral anticancer agents. Yet, the treatment tolerability in older adults has not been fully understood due to their underrepresentation in oncology clinical trials, creating challenges for treatment decision-making and symptom management. The objective of this study was to investigate the tolerance of capecitabine, an example of oral chemotherapy, among older adults with cancer and explore factors associated with capecitabine-related side effects and treatment changes, to enhance supportive care.

Methods

A secondary analysis used combined data from electronic health records and a pilot study of patient-reported outcomes, with a total of 97 adult patients taking capecitabine during 2016–2017, including older adult patients aged 65 years or older (n = 43). The data extracted included patient socio-demographics, capecitabine information, side effects, and capecitabine treatment changes (dose reductions and dose interruptions). Bivariate correlations, negative binomial regression, and multiple linear regression were conducted for data analysis.

Results

Older adults were more likely to experience fatigue (86% vs. 51%, p = .001) and experienced more severe fatigue (β = 0.44, p = 0.03) and hand-foot syndrome (HFS) (β = 1.15, p = 0.004) than younger adults. The severity of fatigue and HFS were associated with the number of outpatient medications (β = 0.06, p = 0.006) and the duration of treatment (β = 0.50, p = 0.009), respectively. Correlations among side effects presented different patterns between younger and older adults. Although more older adults experienced dose reductions (21% vs. 13%) and dose interruptions (33% vs. 28%) than younger adults, the differences were not statistically different. Female sex, breast cancer diagnosis, capecitabine monotherapy, and severe HFS were found to be associated with dose reductions (p-values < 0.05).

Conclusions

Older adults were less likely to tolerate capecitabine treatment and had different co-occurring side effects compared to younger adults. While dose reductions are common among older adults, age 65 years or older may not be an independent factor of treatment changes. Other socio-demographic and clinical factors may be more likely to be associated. Future studies can be conducted to further explore older adults’ tolerance to a variety of oral anticancer agents to generate more evidence to support optimal treatment decision-making and symptom management.

What do hematology residents know about caring for older adults with cancer? A National Survey of Canadian hematology residents' knowledge and interests

INTRODUCTION

As the Canadian population ages, older adults comprise an increasing proportion of those diagnosed and treated for hematologic malignancies. A geriatric oncology curriculum has been recognized as a top priority in the care of older patients with cancer. It is not clear, however, whether hematology trainees receive training in geriatric oncology. We sought to understand residents' views and needs for a geriatric oncology curriculum during hematology residency in Canada.

MATERIALS AND METHODS

We conducted a cross-sectional needs assessment of hematology trainees enrolled in a Canadian residency or advanced fellowship training program within hematology. The survey, which was piloted with three non-hematology residents to ensure user-friendliness, used a combination of Likert scale, multiple-choice, and open-ended questions. The survey comprised three sections: (1) demographic data, (2) current state of geriatric oncology training (amount, content) and (3) attitudes towards learning about geriatric oncology and preferred curriculum components and identified needs. The survey was administered by the study team and distributed electronically to program directors in June 2020. The program directors were asked to forward the survey to trainees registered within their Division of Hematology. Data were analyzed descriptively.

RESULTS

Twenty-nine hematology residents participated (41.4% estimated response rate). Most respondents had not received geriatric oncology teaching (58.6%, n = 17) and have never been taught about geriatric oncology assessment tools (72.4%, n = 21) during hematology residency. Most respondents felt that their program should deliver a geriatric oncology curriculum (96.6%, n = 28). Respondents were most interested in learning about use of geriatric assessment tools for pre-treatment chemotherapy decision-making (86.2%, n = 25), prediction of chemotherapy toxicity (82.8%, n = 24), and to facilitate conversations regarding treatment initiation, continuation, or termination (79.3%, n = 23).

DISCUSSION

Our study highlights the paucity of geriatric oncology training in hematology residency training programs. Our results highlight both the need and interest for a future dedicated geriatric oncology curriculum integrated into hematology training and provide guidance about which topics are most valued by trainees.

Outcomes of curative treatment for head and neck squamous cell carcinoma in very elderly adults ≥80 years old

BACKGROUND

Head and neck cancer treatment can be difficult and advancing age is associated with greater frailty. It is unclear if curative treatment for very elderly patients is beneficial. This study compared outcomes to curative treatment in patients ≥80 aged with HNSCC to patients aged 70-79.

METHODS

Retrospective study of 114 patients diagnosed with HNSCC. Overall survival (OS), Disease-Free Survival (DFS), and local-regional control (LRC) were compared and adjusted for confounders.

RESULTS

Patients aged 70-79 had a higher median OS (35 months [95% CI, 19.58-50.42]) compared with patients aged ≥80 (19 months [11.72-26.28]; p = 0.008) but similar DFS and LRC. KPS < 90 was the stand-alone independent prognostic factor for OS (HR = 2.14 [1.05-4.38]).

CONCLUSION

Very elderly HNSCC patients (aged ≥80) can have favorable outcomes with curative therapy and advanced chronological age alone should not prohibit patients from receiving treatment. Performance status may be a greater predictor of survival outcome than age alone.

Development and validation of the Therapy Preference Scale to understand patients´ systemic cancer treatment preferences

We incorporated questions related to safety, effectiveness and other characteristics of systemic cancer treatment into a self-report questionnaire - the Therapy Preference Scale - that captures patients´ preferences. The authors asked 20 experts to assess content validity and an additional 20 experts, patients and community members to examine face validity and guide revisions. Key revisions included shortening the length, clarifying constructs and providing details to explain the context and trade-offs necessary to balance the risks and benefits of cancer treatment. The content validity index for the final questionnaire was 1.0, indicating that all questions were relevant. Reviewers expressed that the questionnaire would serve an important purpose. Experts, patients and community members guided revisions of the questionnaire and documented its value.

Age Is Not a Barrier: Older Adults With Cancer Derive Similar Benefit in a Randomized Controlled Trial of a Remote Symptom Monitoring Intervention Compared With Younger Adults

This study investigated a remote symptom monitoring intervention to examine if older participants with cancer received a similar magnitude of benefit compared with younger adults with cancer. We analyzed a longitudinal symptom monitoring intervention for 358 participants beginning a new course of chemotherapy treatment in community and academic oncology practices. The study design was a randomized control trial; participants were randomized to the intervention or usual care, the intervention was delivered during daily automated coaching. Older adults with moderate and severe symptoms derived similar benefit as those adults younger than 60 years of age, adherence to the study protocol which involved daily calls was high. There was no significant difference between the 2 age categories; on average, older adult participants made 88% of expected daily calls and younger adult participants made 90% of expected daily calls. Our results challenge the perception that older adults are unwilling or unable to use a technological tool such as interactive voice response and suggest that patient utilization may be guided by other factors, such as ease of use and perceived benefit from the intervention.

Survival of Older Adults With Newly Diagnosed Acute Myeloid Leukemia: Effect of Using Multiagent Versus Single-agent Chemotherapy

BACKGROUND

Controversy exists regarding the optimal chemotherapy regimen for older adults with acute myeloid leukemia (AML).

PATIENTS AND METHODS

We analyzed data from the US National Cancer Data Base of 25,621 patients aged 60 to 79 years, with a diagnosis of AML from 2004 to 2014, who had received single-agent versus multiagent chemotherapy. A Cox proportional hazard model was used for overall survival (OS) analysis for the entire study cohort and separately for patients who had received single-agent (n = 6743) versus multiagent (n = 6743) chemotherapy, matched for age, Charlson comorbidity index, and AML subtype.

RESULTS

The use of multiagent chemotherapy was high overall (70%) but declined with factors, such as increasing age, Charlson comorbidity index, AML subtype other than good risk, academic center, lower rate of high school graduation, and more recent year of diagnosis. Patients treated with multiagent chemotherapy had greater 1-year OS (43% vs. 28%), especially for patients aged 60 to 69 years and those with good-risk AML or Charlson comorbidity index of 0 to 1. OS (hazard ratio, 1.32; 95% confidence interval, 1.28-1.36) remained more favorable for the multiagent chemotherapy group on multivariable analysis. This was confirmed in a matched cohort analysis.

CONCLUSIONS

To the best of our knowledge, this is the largest real-world study that has demonstrated an association between factors such as age, comorbidity, and AML subtype and the use of multiagent chemotherapy. The use of multiagent chemotherapy was associated with improved OS, especially for patients aged <70 years, those with good-risk AML, and those with a low Charlson comorbidity index.
