Acknowledging the relevance of cognitive changes in cancer patients: perspectives of oncology practitioners in Asia

Experiences of women with breast cancer disclosing cancer-related cognitive impairment symptoms to health professionals: a Systematic review and meta-synthesis

OBJECTIVE

Cancer-related cognitive impairment involves changes in cognitive domains among people diagnosed with cancer. This review aimed to explore and synthesize the experiences of women with breast cancer disclosing cancer-related cognitive impairment symptoms to health professionals.

METHODS

A systematic review and meta-synthesis was conducted to generate synthesized findings from existing literature. Six databases were searched from inception until mid-October 2022, with eligible studies appraised using the QualSyst Quality Assessment Checklist.

RESULTS

Three synthesized findings were generated from eight included studies. Findings highlight that women initiated conversations disclosing symptoms and frequently experienced dismissal or minimization from health professionals. Women rarely received information about cognitive impairment symptoms before treatment. Women reported that health professionals could be more involved in managing cognitive impairment symptoms.

CONCLUSION

This meta-synthesis highlights the importance of health professionals providing information before treatment and following up on cognitive impairment symptoms.

CanCOG®: Cultural Adaptation of the Evidence-Based UCLA Cognitive Rehabilitation Intervention Program for Cancer Survivors in Portugal

Cognitive difficulties are highly prevalent and negatively impact cancer survivors' quality of life. The UCLA Cognitive Rehabilitation Intervention Program (in short, UCLA program) is an evidence-based intervention developed and tested in the US to address the cognitive complaints of cancer survivors. Since there are no cognitive rehabilitation programs available for Portuguese cancer-related settings, this study aimed to culturally adapt the UCLA program to Portugal. Nine steps were implemented for this cultural adaptation: needs assessment, initial contacts, translation, cultural adaptation, independent review by a panel of experts (n = 6), focus group discussions with cancer survivors (n = 11), systematization of inputs and improvement of the final materials, fidelity check, and preliminary acceptability assessment. The findings suggested that changes to the original materials were needed. A Portuguese name, "CanCOG^®-Reabilitação Cognitiva no Cancro" (in English "CanCOG^®-Cognitive Rehabilitation in Cancer"), and a logo were created to make it more memorable and appealing for the Portuguese population. The language was adjusted to ensure content accessibility and semantic and conceptual equivalence. Finally, references to several cultural aspects, such as habits, customs, and traditions, were adapted to fit the new cultural context. The UCLA program may be a promising tool to help alleviate the cognitive difficulties reported by cancer survivors in different cultural contexts. Future research is needed to confirm the feasibility, acceptability, and preliminary efficacy of its Portuguese version, "CanCOG^®-Reabilitação Cognitiva no Cancro".

Australian oncology health professionals' knowledge, perceptions, and clinical practice related to cancer-related cognitive impairment and utility of a factsheet

PURPOSE

Cancer-related cognitive impairment (CRCI) can have debilitating effects on cancer survivors' quality of life. Despite this, patients often report a lack of information provided by health professionals (HPs) to assist with understanding and managing cognitive changes. This study aimed to explore Australian oncology HPs' understanding of and clinical practice related to CRCI including the use of a Cancer Council Australia CRCI factsheet.

METHODS

Australian oncology HPs (medical oncologists, cancer nurses, and clinical psychologists) completed a questionnaire that assessed CRCI knowledge, prior to receiving the factsheet. Semi-structured interviews were conducted to explore their perceptions of CRCI and the factsheet. Interviews were recorded, transcribed, and analyzed using framework analysis to identify key themes.

RESULTS

Questionnaires were completed by twenty-nine HPs. Most HPs had moderate to high knowledge of CRCI, yet low knowledge of the relationship between CRCI and cancer. Twenty-six (response rate 90%) HPs; medical oncologists (n = 7), cancer nurses (n = 12), and clinical psychologists (n = 7), consented to be interviewed. Three main themes were identified: (1) Is CRCI impact real or over-rated?; (2) If it is important, they will tell me: identifying and responding to CRCI in clinical practice; and (3) Using a factsheet in clinical practice.

CONCLUSION

This study's multi-disciplinary exploration of Australian oncology HPs' perceptions of CRCI highlighted that health professional perceptions drive CRCI discussions with patients. Further education to support clinicians to discuss CRCI is required. Consideration of the barriers and facilitators within healthcare settings is important for successful integration of the factsheet into routine care.

The perceptions of Australian oncologists about cognitive changes in cancer survivors

OBJECTIVE

Cancer-related cognitive changes (CRCC) can have a profound impact on a cancer survivor's quality of life. However, cancer survivors frequently report receiving limited information about their experience of CRCC from their oncology specialists. This qualitative study aimed to explore the perceptions of oncology specialists regarding CRCC and the potential for their views to influence their decisions about patient care.

METHODS

Thirteen medical oncologists and five radiation oncologists currently practising in Australia participated in this study. Data collection involved individual semi-structured interviews via telephone. Data were audio-recorded, transcribed verbatim and analysed using a thematic approach.

RESULTS

Four key themes emerged: (1) beliefs about the impact of priming on cancer survivors' perceived cognitive function, (2) perceptions of who is more likely to raise concerns of cognitive change, (3) uncertainty of how to best manage CRCC, and (4) the perceived role of oncologists in the management of CRCC.

CONCLUSIONS

CRCC and its impact on the cancer survivor's journey have been under-addressed by oncology specialists, and they are uncertain of potential management strategies. With cancer survival rates increasing, there is a need for specific interventions and management guidelines addressing CRCC and their effects on cancer survivors. Future exploration should focus on the survivor as central to their care and holistic approaches to CRCC management involving all members of the multidisciplinary team.

Chemobrain experienced by breast cancer survivors: a meta-ethnography study investigating research and care implications

BACKGROUND

Cognitive impairment, colloquially termed "chemobrain", occurs in 10-40% of all cancer patients, and is an emerging target of cancer survivorship research.

AIM

This study reviews published qualitative studies to explore cognitive impairments or chemobrain among breast cancer survivors, with particular attention given to the impact on quality of life.

METHOD

Using keywords, we searched ten electronic databases (CINAHL, EMBASE, Proquest, OVID SP, MEDLINE, Oxford Journal, Science Direct, PubMED).

FINDINGS

Of 457 papers, seven relevant papers were included. Data was extracted and concepts were analysed using a meta ethnography approach. Four second order intepretations were identified, on the basis of which, four third order intrepretations were constructed. Linked together in a line of argument, was a consistent account on their struggles to self-manage the chemobrain impairments that impact their daily lives. Five concepts emerged from the analysis of the primary findings: i) real experiences of cognitive changes, ii) calls for help, iii) impact of cognitive impairments, iv) coping and v) survivorship and meaning. Further synthesis resulted in four new order intepretations: i) The chemobrain struggle, ii) The substantial impact of chemobrain on life domains, iii) The struggle to readjust and to self manage, and iv) 'thankful yet fearful' representation.

DISCUSSION

Awareness of cognitive changes were context-dependent on healthcare settings and cultural contexts as strong determinants. Subjects verified the existence of chemobrain but healthcare providers mis-recognised, under-recognised, and sometimes negated it perhaps due to its unknown aetiology. Asian breast cancer survivors appear less vocal than their western counterparts.

CONCLUSION

The current literature on the lived experiences of how women experienced chemobrain provides a consistent report that chemobrain is real, persistent and with detrimental impacts on quality of life - manifested as a constant struggles. A greater awareness of the effects of chemobrain with improved functional assessment and interventions is warranted.
