Relationship between Uncertainty and Emotions in Advanced Lung Cancer Patients after Initial Therapy

Uncertainty among patients with advanced-stage lung cancer

BACKGROUND

Uncertainty is the inability to define the meaning of illness-related events, which may result in anxiety, depression, poor coping, the self-perception of being a burden and low quality of life. Uncertainty among Thai patients with advanced-stage lung cancer (ASLC) has not been well documented.

AIMS

To assess uncertainty in patients with ASLC.

METHODS

A cross-sectional survey design was adopted. Data were collected from 60 patients with ASLC at a university hospital. A demographic data form and the Mishel Uncertainty in Illness Scale (MUIS) were used to collect data. The data were analysed using descriptive statistics.

RESULTS

The patients had moderate levels of uncertainty in illness (83.73±15.25). Ambiguity about the illness and unpredictability of the prognosis scored at a moderate level for patients, while complexity of treatment and the system of care and inconsistency or lack of information, about the diagnosis or severity of the illness were at a low level.

CONCLUSION

The results of this study may help healthcare professionals better understand and manage uncertainty in patients with ASLC.

Relationship between self-disclosure and anticipatory grief in patients with advanced lung cancer: the mediation role of illness uncertainty

Objective

To study the relationship between self-disclosure, illness uncertainty (IU) and anticipatory grief (AG) in patients with advanced lung cancer.

Methods

This is a cross-sectional study using convenience sampling method, in which 316 patients with advanced lung cancer who were hospitalized in a tertiary hospital in Wuxi City, China, from November 2022 to April 2023 were sampled. The Preparatory Grief in Advanced Cancer Patients, Mishel Uncertainty in Illness Scale, and the Distress Disclosure Index Scale (DDI) were selected to analyse the status quo, correlations, and the mediating effect of illness uncertainty on the relationship between self-disclosure and anticipatory grief in advanced lung cancer patients.

Results

The total self-disclosure score of advanced lung cancer patients was (36.35 ± 9.25), the total score of IU was (56.92 ± 15.65), and the score of AG was (52.29 ± 9.08); the results of correlation analyses showed that IU was negatively correlated with self-disclosure in advanced lung cancer patients (p < 0.05) and positively correlated with AG (p < 0.05), and self-disclosure was negatively correlated with AG (p < 0.05);the mediating effect rate of IU between self-disclosure and AG in advanced lung cancer patients was 49%.

Conclusion

The AG of advanced lung cancer patients was at a medium-high level, and IU had a significant mediating effect between self-disclosure and AG of advanced lung cancer patients; by increasing the level of patients' self-disclosure, IU could be effectively alleviated, and ultimately the AG of the patients could be reduced.

The past and future of uncertainty in advanced illness: a systematic scoping review of underlying cognitive processes

BACKGROUND

To explain what cognitive capacity shapes uncertainty in advanced illness by identifying the types of evidence, mapping underlying cognitive processes to uncertainty, and outlining future directions for research and interventions.

DESIGN

A systematic scoping review of mixed study designs was carried out following the methodological framework of Arksey and O'Malley (2005) and using qualitative content analysis.

METHODS

PubMed, CINAHL, Embase, and PsycINFO were searched for original studies published in full and in English through December 2021 that reported on uncertainty in illness and related cognitions, cognitive science, or cognitive functions.

RESULTS

After screening 978, 18 articles met the inclusion criteria for review. We found the cognitive capacity of mental time travel - to relive the past or foresee life in the future - interacted with episodic memory retrieval to inform decision-making, and prospection to imagine, predict or prepare for future outcomes to determine lesser or greater uncertainty in advanced illness.

CONCLUSIONS

Mental time travel is a fundamental cognitive function when the future is limited by an advanced illness, to review life as a meaningful narrative. The role of mental time travel to construct or make sense of uncertain futures inherent in advanced illness can inform theory and targets for intervention.

Dyadic effects of social support, illness uncertainty on anxiety and depression among lung cancer patients and their caregivers: a cross-sectional study

OBJECTIVES

To explore the dyadic relationships between perceived social support, illness uncertainty, anxiety, and depression among lung cancer patients and their family caregivers. To examine the potential mediating role of illness uncertainty and the moderating role of disease stage in lung cancer patient-caregiver dyads.

METHODS

A total of 308 pairs of lung cancer patients and their family caregivers from a tertiary hospital in Wuxi, China, from January 2022 to June 2022 were included. Participants' perceived social support, illness uncertainty, anxiety, and depression were assessed by corresponding questionnaires. To test for dyadic relationships between the variables, we employed the actor-partner interdependence mediation model.

RESULTS

There were actor and partner effects of both patient and caregiver perceived social support on anxiety and depression, and illness uncertainty mediated the effect of perceived social support on anxiety and depression. Lung cancer stage plays a moderating role in lung cancer patient-caregiver dyads. There is an indirect positive partner effect of perceived social support from family caregivers on anxiety and depression in patients with early lung cancer; there is a direct or indirect negative partner effect of social support from family caregivers on anxiety and depression in patients with advanced lung cancer.

CONCLUSIONS

This study confirmed the dyadic interdependence between perceived social support, illness uncertainty, anxiety, and depression among lung cancer patients and family caregivers. Furthermore, studies on differences between different lung cancer stages may provide a theoretical basis for different dyadic supportive interventions based on lung cancer stages.

Randomized double-blind placebo-controlled multicenter trial for the effects of a polyherbal remedy, Yokukansan (YiganSan), in smokers with depressive tendencies

BACKGROUND

Smoking and depression are closely related and form a vicious cycle. Yokukansan (YiganSan) is a polyherbal remedy that has the effect of calming neuropsychiatric symptoms such as anger and irritation. To examine the efficacy of Yokukansan during smoking cessation (SC) therapy in smokers with depressive tendencies but without major depressive disorders requiring pharmacotherapy.

METHODS

A multicenter, double-blind, randomized, placebo-controlled, parallel-group comparison trial was conducted between June 2016 and May 2020 at 12 centers of the National Hospital Organization, Japan. This trial targeted smokers who first visited the SC outpatient clinics, did not receive any pharmacological treatment at the psychiatric or psychosomatic department, and scored 39 or more on the self-rating depression scale (SDS). Participants (n = 198) were randomly assigned to either the Yokukansan or placebo groups. The trial drug was initiated with the start of the SC treatment and continued for 12 weeks. The primary outcome was the high success rate of the SC treatment, and the secondary outcomes included changes in scores of the SDS and the Profile of Mood States (POMS) instrument.

RESULTS

The success rate of the SC treatment was similar between the placebo (63%) and Yokukansan (67%) groups (P = .649). The SDS scores (placebo: mean difference [MD] = -3.5, 95% confidence interval [CI][-5.8, -1.2], d = 0.42; Yokukansan: MD = -4.6, 95%CI[-6.8, -2.3], d = 0.55), and the "tension-anxiety" POMS-subscale scores (placebo: MD = -1.6, 95%CI[-2.5, -0.7], d = 0.52; Yokukansan: MD = -1.6, 95%CI[-2.9, -0.3], d = 0.36) showed significant improvement in both groups after the SC treatment. However, "depression-dejection" improved in the Yokukansan group (MD = -1.9, 95%CI[-3.1, -0.7], d = 0.44) but not in the placebo group (MD = -0.1, 95%CI[-1.0, 0.7], d = 0.04). Significant improvement in "fatigue" was noted in the Yokukansan group (MD = -2.1, 95%CI[-3.4, -0.9], d = 0.47) but not in the placebo group (MD = -0.5, 95%CI[-1.8, 0.8], d = 0.11). The time × group interaction on the improvement in "depression-dejection" was significant (P = .019).

CONCLUSIONS

Yokukansan does not increase the SC treatment's success rate but has additional positive effects on the psychological states due to the SC treatment in smokers with depressive tendencies but without apparent mental disorders.

Using Liminality and Subjunctivity to Better Understand How Patients With Cancer Experience Uncertainty Throughout Their Illness Trajectory

Uncertainty is a central theme in the illness experiences of older cancer patients throughout their illness trajectory. Mishel's popular theory on uncertainty during illness approaches uncertainty as an outcome and is characterized by the patient's inability to find meaning in illness events. This study used the concepts of liminality and subjunctivity to explore uncertainty throughout the illness trajectory of cancer patients. We interviewed 18 older (age range = 57-92 years) patients with breast cancer or gastro-intestinal cancer 3 to 4 years post diagnosis. Our analysis is based on the QUAGOL guide that draws on elements of grounded theory such as constant comparison. We found that liminality and subjunctivity provide a useful frame for understanding uncertainty with a specific focus on its productive potential and meaning making. Health care professionals should be open to acquiring a complete picture of patients' diverse and dynamic experiences of uncertainty in the different stages of their illness trajectory.

Uncertainty and unmet care needs before and after surgery in patients with gastric cancer: A survey study

Uncertainty and unmet care needs constantly change in patients with cancer. However, there is a lack of information regarding the changing pattern of these variables. This study aimed to examine the changes in uncertainty and unmet care needs at diagnosis and after surgery among patients with gastric cancer. In total, 86 individuals completed a self-reported questionnaire. Data were collected twice - to measure uncertainty and unmet care needs at cancer diagnosis (T1), and after surgery (T2) - and analyzed using descriptive analysis and a dependent t-test. Uncertainty was moderate at both periods but significantly higher at T1. Unmet care needs were highest in the information domain and lowest in the sexuality domain at both T1 and T2. Only the physical/daily living domain were significantly higher at T2, whereas the information, psychological, and patient care/support domains were significantly higher at T1. Different levels of uncertainty and unmet needs were identified at T1 and T2. Healthcare providers should assess changing unmet care needs at each stage of the cancer trajectory and provide related nursing care and information to this population, even immediately after diagnosis.
