Exploring clinical determinants and anxiety symptom domains among Asian breast cancer patients

Attention Dysregulation in Breast Cancer Patients Following a Complementary Alternative Treatment Routine: A Double-Blind Randomized Trial

Introduction:

Breast cancer patients and survivors frequently report fatigue, emotional, and cognitive disturbances, which reduce performance at all levels of occupation and make life quality issues a considerable clinical concern. The aim of this study is to evaluate attention and emotion regulation across radiotherapy period and the possible effects of complementary alternative medicine (CAM).

Methods:

Fifty-seven patients with unilateral breast cancer underwent surgery and systemic chemotherapy before participating in this double-blind randomized study. Two thirds were given CAM (n = 38) while the rest received placebo (carrier only, n = 19). Patients’ attention and anxiety were physiologically tested at baseline, 2 and 4 weeks during the radiation period as well as 1-month after the end of radiation session.

Results:

Both groups showed similar levels of anxiety with no significant differences at baseline nor post-radiotherapy. Long-term significant recovery of attention performance was observed in the CAM patients, accompanied by a similar tendency in anxiety level, measured by the eye-blink probability.

Conclusions:

This study physiologically validates the attention impairment reported among breast cancer survivors; also, it depicted a beneficial late-effect of a routine CAM on attention dysregulation. The suggested non-invasive physiological measures can physiologically monitor patients’ psychological and cognitive well-being as well as evaluate the beneficial effect of CAM in breast cancer patients by assessing their coping ability to support the treatment plan. Thus, the results have potential clinical implications on patients’ and survivors’ quality of life.

Might anxiety disorders promote head and neck cancer development?

Cancer patients present a higher risk of experiencing anxiety disorders (AD). However, it is not clear if AD might be associated with cancer development. Thus, our study aimed to evaluate if AD might be related to head and neck squamous cell carcinoma (HNSCC) development. The combination of an applied animal basic study and a retrospective diagnostic case and control study in patients was performed. As a result, we obtained that stress reduced the locomotor activity of the animals in the group stress and stress + 4NqO (p < 0.0001). The stress showed no influence on the progression of neoplasia in mice. In the same way, the case group did not present differences in anxiety scores in comparison to control. Moreover, no association between HNSCC staging and anxiety scores was observed. In conclusion, our in vivo findings in humans and animals have shown that there is no relationship between AD and oral squamous cell carcinoma.

A comparison of psychosocial care preferences of breast cancer women in Mainland China and Hong Kong

PURPOSE

Despite shared cultural values, Mainland China's health care system differs from that of Hong Kong. We compared preferences for psychosocial care in Mainland breast cancer women with their Hong Kong counterparts to determine core preferences for, and correlates of, clinical psychosocial care implementation.

METHODS

Two hundred eighty breast cancer patients from 23 hospitals located in 15 provinces across Mainland China were recruited to complete the 55-item Chinese version of the Australian National Health and Medical Research Council's National Breast Cancer Centre assessment. Items ranked by proportions of women endorsing them as "essential" for care were compared with similar rankings by Hong Kong Chinese women with breast cancer.

RESULTS

Valid response rate was 83% (231/280). Among 231 breast cancer patients, greater than 40% endorsed 15/55 items as essential for effective psychosocial care. Of the top 10 ranked "repeatable" items, seven items were common to both Chinese and Hong Kong breast cancer women, while of the top 10 ranked "once-only" items, nine were common. Mainland breast cancer women ranked help with anxiety and social roles higher than did their Hong Kong counterparts. Demographic factors significantly associated with psychosocial care needs included ethnicity, age, income source and level, religious beliefs, education level, marital status, residential status, and current therapies.

CONCLUSIONS

Chinese breast cancer patients prioritize both disease and treatment information and psychosocially sensitive care, making these core items in comprehensive psychosocial care implementation by clinicians and nurses.

Replication and Meta-analysis of the Association between BDNF Val66Met Polymorphism and Cognitive Impairment in Patients Receiving Chemotherapy

Cancer-related cognitive impairment (CRCI) adversely affects cancer patients. We had previously demonstrated that the BDNF Val66Met genetic polymorphism is associated with lower odds of subjective CRCI in the multitasking and verbal ability domains among breast cancer patients receiving chemotherapy. To further assess our previous findings, we evaluated the association of BDNF Val66Met polymorphism with subjective and objective CRCI in a temporally separate cohort of patients and pooled findings from both the original (n = 145) and current (n = 193) cohorts in a meta-analysis. Subjective CRCI was assessed using FACT-Cog. Objective CRCI was evaluated using computerized neuropsychological tests. Genotyping was carried out using Sanger sequencing. The association of BDNF Val66Met genotypes and CRCI was examined with logistic regression. A fixed-effect meta-analysis was conducted using the inverse variance method. In the meta-analysis (n = 338), significantly lower odds of CRCI were associated with Met allele carriers based on the global FACT-Cog score (OR = 0.52, 95% CI 0.29–0.94). Furthermore, Met allele carriers were at lower odds of developing impairment in the domains of memory (OR = 0.34, 95% CI: 0.17–0.70), multitasking (OR = 0.33, 95% CI: 0.18–0.59), and verbal ability (OR = 0.46, 95% CI: 0.24–0.88). Consistent with the previous study, lower odds of subjective CRCI among patients with the BDNF Met allele was observed after adjusting for potential confounders in the multitasking (OR = 0.30, 95% CI: 0.14–0.67) domain. In conclusion, carriers of the BDNF Met allele were protected against global subjective CRCI, particularly in the domains of memory, multitasking, and verbal ability. Our findings further contribute to the understanding of CRCI pathophysiology.

Assessment of mental health literacy in patients with breast cancer

INTRODUCTION

Psychosocial distress is often underdiagnosed and undertreated among breast cancer patients due to the poor recognition of the associated symptoms and inadequate knowledge of the treatments available.

OBJECTIVE

To evaluate the mental health literacy of breast cancer patients by assessing (1) their ability to recognize the symptoms of anxiety, fatigue, depression, and cognitive disturbances, and (2) their knowledge of help-seeking options and professional treatments.

METHODS

In this multi-center, cross-sectional study, early-stage breast cancer patients receiving chemotherapy underwent four assessments to measure their levels of anxiety, depression, fatigue, and cognitive disturbances. With the aid of cancer-specific vignettes, a questionnaire was administered to evaluate their mental health literacy.

RESULTS

Fifty-four patients were recruited (77.7% Chinese, aged 52.7 ± 8.5 years). Clinically significant anxiety (15.1%), fatigue (27.8%), and cognitive disturbances (25.9%) were more prevalent than depression (5.6%). Although the majority of the patients could recognize the symptoms of fatigue accurately (75.9%), less than half could identify those of anxiety (35.2%), depression (48.1%), and cognitive disturbances (48.1%). Patients were more receptive to help from their family members (score: 3.39 out of 4.00) and oncologists (score: 3.13) than from other mental health specialists, such as psychiatrists (score: 2.26) and psychologists (score: 2.19) in the management of their psychosocial distress. Approximately half of the patients indicated that embarrassment and fear were their main barriers to seeking professional treatment (55.6%).

CONCLUSIONS

Our results suggest that the mental health literacy of breast cancer patients was inadequate. Intervention and management strategies could be implemented to teach these patients about evidence-based treatments and professional help that are specific to mental disorders.

Symptom burden and medication use in adult sarcoma patients

PURPOSE

Limited data are available on how symptom burden affects health-related quality of life (HRQoL) in patients with sarcoma. This study aims to describe the symptom burden, HRQoL, and medication use in adult sarcoma patients.

METHODS

A single-center, cross-sectional study was conducted, and 79 patients were evaluated using three tools: the Rotterdam Symptom Checklist (RSCL), the Beck Anxiety Inventory (BAI), and the Functional Assessment of Cancer Therapy scale-General (FACT-G). Patients' demographic and clinical information, medication history, and use of concomitant medications were recorded. The proportion of patients with clinically significant RSCL score for a particular symptom was compared with the percentage of patients receiving medication for that symptom.

RESULTS

The mean age was 57.3 ± 15.2 years, with majority of the patients diagnosed with stromal tumor (46.8 %), leiomyosarcoma (15.2 %), and liposarcoma (10.1 %). The most prevalent physical symptoms experienced were tiredness (2.38 ± 1.00), lack of energy (2.04 ± 1.02), and difficulty sleeping (2.00 ± 1.15). The most common psychological symptoms experienced were irritability (1.92 ± 1.01), worrying (1.86 ± 0.90), and anxiety (1.68 ± 0.74). Few (6.3 %) patients received hypnotics while 33.0 % of patients reported difficulty sleeping. A proportion of patients (27.9 %) reported experiencing lack of appetite with only 1.3 % received appetite stimulants.

CONCLUSION

Adult sarcoma patients experience significant physiological and psychological symptom burden, which has a strong negative impact on HRQoL, with a number of physiological symptoms undertreated with pharmacotherapy.

Psychometric properties and measurement equivalence of the English and Chinese versions of the functional assessment of cancer therapy-cognitive in Asian patients with breast cancer

OBJECTIVE

This study was designed to examine the psychometric properties and measurement equivalence of the English and Chinese versions of the Functional Assessment of Cancer Therapy-Cognitive Function (Version 3) (FACT-Cog) in multiethnic Asian patients with breast cancer.

METHODS

This prospective study involved patients with breast cancer from the National Cancer Centre Singapore. The concurrent validity of the FACT-Cog was assessed according to its strength of correlation with the validated European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 cognitive functioning scale, and its association with fatigue, global health status, and anxiety. The known-group validity was assessed on the basis of receipt of chemotherapy. Factor analysis was conducted to ascertain the one-factor structure of each cognitive domain. The reliability was evaluated by using Cronbach's alpha and intraclass correlation coefficient within the cognitive domains. Multiple regression analyses were performed to compare the total scores between the two language versions, adjusting for covariates.

RESULTS

A total of 185 English-speaking and 143 Chinese-speaking patients were recruited. Both the English and Chinese FACT-Cog total scores correlated strongly with the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 cognitive functioning scale scores (r = 0.725 and 0.646), whereas correlations with fatigue, anxiety, and global health status were weak to moderate (|r| = 0.376-0.589). Regarding the known-group validity, more severe perceived cognitive disturbance was observed among patients receiving chemotherapy than among those who were not for both versions (P = .010 and .008, respectively). Internal consistencies within the cognitive domains were high (Cronbach's α 0.707-0.929), and test-retest reliability was satisfactory for both versions (intraclass correlation coefficient 0.762 and 0.697). The measurement equivalence between the English and Chinese versions was established for all domains except the multitasking domain.

CONCLUSION

The English and Chinese versions of the FACT-Cog are valid, reliable, and equivalent for clinical and research use.
