Effects of physical activity on the quality of life in taiwanese lung cancer patients receiving active treatment or off treatment

Caregivers’ contribution to self-care for patients treated with oral anticancer agents: A qualitative descriptive study

PURPOSE

To adequately manage oral anticancer agents (OAAs) therapy, appropriate self-care behaviours must be implemented. Informal caregivers could support and contribute to patient self-care. This study aimed to explore and describe the caregiver contribution to self-care and their related experience of caring among informal caregivers of patients on OAAs.

METHODS

Qualitative descriptive design. We conducted semi-structured interviews, which were transcribed, read in depth, and analysed with deductive and inductive content analysis, according to Mayring. Adult informal caregivers (>18 years) of elderly patients (>65 years) with solid malignancies undergoing OAAs therapy for at least 3 months were included.

FINDINGS

Twenty-three caregivers were interviewed with mean age of 57,2 (SD ± 15,8). A total of 18 codes from the qualitative content analysis were found, of which ten were referred to caregiver contribution and classified into the three dimensions of self-care maintenance (i.e. behaviours to maintain illness stable), self-care monitoring (i.e., tracking symptoms and side effects), and self-care management (i.e., management of worsening symptoms), according to the Middle Range Theory of Self-Care of Chronic Illnesses. The eight codes on caregiver experience were aggregated into two main themes: negative aspects (i.e., burden, emotional state, self-denial, social isolation) and positive aspects of caregiving.

CONCLUSION

Healthcare professionals should consider the importance of caregiver role in supporting their loved one treated with OAAs, also taking into account their needs to prevent burdensome situations. A holistic view in which a patient-centred approach is established should be encouraged through the communication and education of the dyad.

The determinants of health-related quality of life among patients with newly diagnosed lung cancer in Taiwan: A cross-sectional study

BACKGROUND

Although considered one of the most important prognostic factors for lung cancer patients, the health-related quality of life (HRQOL) of the newly diagnosed lung cancer population remains scarcely focused on in the literature. Therefore, we aimed to identify the determinants of HRQOL among newly diagnosed lung cancer patients in Taiwan.

METHODS

Two hundred and fifty patients newly diagnosed with lung cancer were recruited from a medical center in northern Taiwan through convenience sampling. Four structured questionnaires, including the Taiwanese version of the MD Anderson symptom inventory (MDASI-T), the Taiwanese version of the Pittsburgh Sleep Quality Index (PSQI-T), the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and the World Health Organization Quality of Life-BREF (WHOQOL-BREF), were used to collect data. Further, a multivariate stepwise linear regression was conducted to determine the independent risk factors for HRQOL. A p value of less than 0.05 was considered statistically significant.

RESULTS

The patients (mean age was 61.04 years, 51.2% male, 94.0% non-small-cell lung cancer, 56.4% stage IIIB-IV) had moderate levels of HRQOL among the physical, psychological, social, and environmental domains, as well as overall QOL. HRQOL was not correlated with married status, religion, and comorbidity. Gender, age, family income, smoking status, cancer stage, ECOG PS scores, PA, symptom burden (severity and interference), and PSQI global scores were correlated with HRQOL. Notably, symptom severity was the dominant negative predictor affecting the psychological and environmental domains of QOL (β = -4.313 and -3.500, respectively), accounting for 23.2% and 14.6% of the variance, respectively. On the other hand, symptom interference was the dominant negative predictor affecting the physical and social domains of QOL, as well as overall QOL (β = -3.592, -1.984, and -0.150, respectively), accounting for 44.4%, 15.0%, and 24.1% of the variance, respectively.

CONCLUSION

Newly diagnosed lung cancer patients suffered symptom severity and interference that significantly impaired their HRQOL; particularly, symptom interference affected the physical domain of QOL. Healthcare professionals should pay more attention to cancer-related symptom severity, symptom interference, and HRQOL changes when caring for newly diagnosed lung cancer patients.

Postoperative Symptom Burden in Patients Undergoing Lung Cancer Surgery

CONTEXT

Previous studies on quality of life (QOL) after lung cancer surgery have identified a long duration of symptoms postoperatively. We first performed a systematic review of QOL in patients undergoing surgery for lung cancer. A subgroup analysis was conducted focusing on symptom burden and its relationship with QOL.

OBJECTIVE

To perform a qualitative review of articles addressing symptom burden in patients undergoing surgical resection for lung cancer.

METHODS

The parent systematic review utilized search terms for symptoms, functional status, and well-being as well as instruments commonly used to evaluate global QOL and symptom experiences after lung cancer surgery. The articles examining symptom burden (n = 54) were analyzed through thematic analysis of their findings and graded according to the Oxford Centre for Evidence-based Medicine rating scale.

RESULTS

The publication rate of studies assessing symptom burden in patients undergoing surgery for lung cancer have increased over time. The level of evidence quality was 2 or 3 for 14 articles (cohort study or case control) and level of 4 in the remaining 40 articles (case series). The most common QOL instruments used were the Short Form 36 and 12, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, and the Hospital Anxiety and Depression Score. Thematic analysis revealed several key findings: 1) lung cancer surgery patients have a high symptom burden both before and after surgery; 2) pain, dyspnea, cough, fatigue, depression, and anxiety are the most commonly studied symptoms; 3) the presence of symptoms prior to surgery is an important risk factor for higher acuity of symptoms and persistence after surgery; and 4) symptom burden is a predictor of postoperative QOL.

CONCLUSION

Lung cancer patients undergoing surgery carry a high symptom burden which impacts their QOL. Measurement approaches use myriad and heterogenous instruments. More research is needed to standardize symptom burden measurement and management, with the goal to improve patient experience and overall outcomes.

[Applying Extended Theory of Planned Behavior for Lung Cancer Patients Undergone Pulmonary Resection: Effects on Self-Efficacy for Exercise, Physical Activities, Physical Function, and Quality of Life]

PURPOSE

This study aims to examine the effects of nursing interventions based on the Extended Theory of Planned Behavior (ETPB) regarding self-efficacy for exercise (SEE), physical activity (PA), physical function (PF), and quality of life (QOL) in patients with lung cancer who have undergone pulmonary resection.

METHODS

This quasi-experimental study was conducted between July 2015 and June 2018 in two university-affiliated hospitals. The intervention included pre-operative patient education, goal setting (action and coping planning), and feedback (behavior intention and perceived behavioral control). The intervention group (IG) (n=51) received nursing interventions from the day before surgery to 12 months after lung resection, while the comparison group (CG) (n=36) received usual care. SEE, PA, PF (dyspnea, functional status, and 6-minute walking distance [6MWD]), and QOL were measured before surgery and at one, three, six, and 12 months after surgery. Data were analyzed using the χ² test, Fisher's exact test, Mann-Whitney U test, t-test, and generalized estimation equations (GEE).

RESULTS

There were significant differences between the two groups regarding SEE (χ²=13.53, p=.009), PA (χ²=9.51, p=.049), functional status (χ²=10.55, p=.032), and 6MWD (χ²=15.62, p=.004). Although there were no time or group effects, the QOL mental component (Z=-2.78, p=.005) of the IG was higher than that of the CG one month after surgery. Interventions did not affect dyspnea or the QOL physical component.

CONCLUSION

The intervention of this study was effective in improving SEE, PA, functional status, and 6MWD of lung cancer patients after lung resection. Further extended investigations that utilize ETPB are warranted to confirm these results.

Effect of Wellness Education on Quality of Life of Patients With Non-Small Cell Lung Cancer Treated With First-Line Icotinib and on Their Family Caregivers

Objective: To examine the effects of a wellness-education intervention on quality of life (QOL) of patients with NSCLC treated with icotinib and on their caregivers. Methods: This feasibility study was a prospective pilot randomized controlled trial to evaluate a wellness-education intervention in NSCLC patients and caregivers undergoing icotinib treatment. The participants in the wellness-education group were provided with well-being information over 8 weeks. The Family Environment Scale (FES), Functional Assessment of Cancer Therapy–Lung (FACT-L), Caregiver QOL Index–Cancer Scale (CQOLC), and Hospital Anxiety and Depression Scale (HADS) were measured at baseline prior to randomization and after 8 weeks. Patients completed the FACT-L and HADS, caregivers completed the CQOLC and FES. Results: 67 patients/caregivers in the wellness-education group and 71 in the control group could be analyzed. Feasibility targets were the following: (1) >70% study enrollment of eligible patients; (2) >90% of participants completing this study; (3) <10% missing data. Wellness-education group had better change scores at 8 weeks for the emotional well-being subscale of FACT-L (12.8 vs 15.6, P = .014), anxiety subscale of HADS (6.1 vs 6.7, P = .030), adaptation (66.0 vs 54.7, P = .037) and financial subscales of CQOLC (70.8 vs 69.8, P = .044), and the cohesion (7.3 ± 1.8 vs 5.7 ± 1.7, P= .021) and conflict (3.4 ± 1.9 vs 4.5 ± 1.7, P = .031) subscales of the FES. Conclusion: Wellness-education in patients/caregivers with NSCLC treated with icotinib are feasible and could improve patients’ QOL and their relationship with caregivers.

Patients with Chronic Musculoskeletal Pain of 3-6-Month Duration Already Have Low Levels of Health-Related Quality of Life and Physical Activity

PURPOSE OF REVIEW

To determine the level of physical activity and health-related quality of life in patients with chronic musculoskeletal pain of 3-6-month duration who have not been diagnosed or treated before.

RECENT FINDINGS

Low levels of quality of life and physical activity have been reported for patients with musculoskeletal pain with a duration of longer than 6 months. This study assessed the levels of quality of life and physical activity at the beginning stage of chronic musculuskeletal pain. Prospective cross-sectional study carried out at a musculoskeletal and sports medicine clinic. Eighty-five consecutive patients with muskuloskeletal (i.e., spine, peripheral joint, muscle, tendon) pain of 3-6-month duration, not diagnosed before, age 14 and older, and from either gender were recruited. Short Form-36 Health Survey and International Physical Activity Questionnaire long were administered during assessments. Scores on subscales of Short Form-36 Health Survey and total scores of International Physical Activity Questionnaire were used as outcome measures. A total of 85 patients with an age range of 15-86 (51.22 ± 15.99) were enrolled. There were 23 male (27.06%) and 62 (72.94%) female subjects. Forty-six (54.11%) patients had three or less painful regions; 39 (45.88%) had more than three painful regions. Majority of the patients had low scores on both Short Form-36 Health Survey subscales and International Physical Activity Questionnaire. Forty-nine patients had low, 32 patients had moderate, and 4 patients had high level of physical activity. Overall, females had lower level of physical activity in all age groups. All patients had less than optimal scores on all subscales of Physical Health and Mental Health scales of the Short Form-36. The female patients had lower scores in role physical and bodily pain subscales of physical health. Patients with musculoskeletal pain duration of 3-6 months have low levels of physical activity and health-related quality of life at the time of their first evaluation.

How is physical activity measured in lung cancer?A systematic review of outcome measures and their psychometric properties

Physical activity (PA) levels are low in patients with lung cancer. Emerging evidence supports the use of interventions to increase PA in this population. We aimed to (1) identify and synthesize outcome measures which assess PA levels in patients with lung cancer and (2) to evaluate, synthesize and compare the psychometric properties of these measures. A systematic review of articles from searches was conducted of five electronic databases and personal records. Eligible studies were those which assessed PA using either performance-based or patient-reported measures. For aim 2, studies identified in aim 1 reporting on at least one psychometric property (validity, reliability, responsiveness or measurement error) were included. Two independent reviewers assessed eligibility and risk of bias with the COnsensus-based Standards for the selection of health status Measurement INstruments. Thirty-four studies using 21 different measures of PA were identified. Seventeen studies used performance-based measures. The Godin Leisure Time Exercise Questionnaire (GLTEQ) was the most frequently used patient-reported measure. Psychometric properties were reported for 13 of these measures and most frequently for movement sensors. Two studies reported on properties of the GLTEQ. Quality ratings for risk of bias were low. There is significant heterogeneity amongst studies regarding method of PA measurement along the lung cancer continuum. Greater consensus could be achieved by using a consensus approach such as a Delphi process. Future studies should include assessment of psychometric properties of the measurement tool being used. Currently, it is recommended where feasible, both performance-based and patient-reported measurements of PA should be undertaken.

Longitudinal study on the impact of physical activity on the symptoms of lung cancer survivors

PURPOSE

To examine the effect of physical activity on the physical and psychosocial symptoms of lung cancer survivors.

METHODS

A longitudinal design was used in this study. Participants were recruited from the chest and surgical departments of medical centers in Taiwan. The instruments used were the Godin Leisure-Time Exercise Questionnaire and the Taiwanese version of the M.D. Anderson Symptom Inventory.

RESULTS

In total, 185 survivors were followed up for 6 months (response rate 66%). Disturbed sleep was the most prevalent symptom in the participants. A generalized estimating equation (GEE) method was employed to analyze the relationships among intensity of physical activity, symptom severity, and symptom interference in the daily life of the participants. Regarding symptom severity, significant differences were observed in fatigue, drowsiness, and disturbed sleep between the participants who engaged in moderate physical activity and those who did not engage in any physical activity. Regarding symptom interference, the participants who engaged in light physical activity experienced a significantly lower level of symptom interference than did those with a sedentary lifestyle.

CONCLUSION

This is the first study to explore the role of physical activity in alleviating symptoms in lung cancer survivors by using the GEE method. The results suggest that physical activity plays an essential role in alleviating the physical and psychological symptoms of lung cancer survivors.

Exercise preferences, levels and quality of life in lung cancer survivors

PURPOSE

Lung cancer poses multiple challenges to adopting an exercise (EX) program, and the ideal timing of an EX program to improve quality of life (QoL) is unknown. This study explored the EX counselling and programming preferences of lung cancer survivors and examined the association of EX before diagnosis, during treatment and after treatment on QoL.

METHODS

Cross-sectional, retrospective survey design in a sample of lung cancer survivors. EX preferences were compared between patients who had received radical chest radiation or lung surgery versus those who had not. EX was measured by self-report using the Godin Leisure Time Exercise Questionnaire (GLTEQ). Separate linear regression models, controlling for significant covariates, examined the association of EX at each time point with scores on QoL measures and subscales.

RESULTS

Participants (N = 66, M age 66.4 ± 9.1) were between 4 months and 11.5 years after lung cancer diagnosis (M = 31.7 ± 22.9 months). Patients who had lung surgery were more likely to prefer to start an EX program during adjuvant treatment than those who did not have surgery (t(33) = 2.43, p = .025). Compared to prediagnosis EX (M = 36.7 ± 56.0 MET h/week), EX levels declined significantly during (M = 12.4 ± 25.0 MET h/week) and after (M = 12.3 ± 17.4 MET h/week) treatment (p < .05). After controlling for disease stage and income, regression models were not significant, but EX after treatment was a significant individual predictor of fatigue (β = .049, p = .006) and QoL measured by the Chronic Respiratory Disease Questionnaire (β = .163, p = .025).

CONCLUSIONS

Lung cancer patient preferences indicate that EX program timing should take into account whether the patient has undergone surgery. Lung cancer survivors' EX levels declined after diagnosis and engaging in EX after treatment may improve fatigue and QoL.

Exercise intervention for patients diagnosed with operable non-small cell lung cancer: a qualitative longitudinal feasibility study

PURPOSE

The purpose was to explore operable lung cancer patient experiences with an exercise intervention from a longitudinal perspective according to patient motivation and patient perceived benefits and barriers of exercise.

METHODS

Nineteen patients enrolled in an exercise intervention 2 weeks post-surgery participated in qualitative interviews at three time points. A criteria sampling strategy was applied. Ricoeur's phenomenological hermeneutical philosophy inspired the analysis.

RESULTS

Patients initiated exercising median 15 days postoperative. Eight patients included in the interview study dropped out of the intervention due to side effects of chemotherapy (n = 3) and external circumstances (n = 5). The mean attendance rate for the eleven participants who completed the intervention was 82 %. No patients experienced severe adverse events. Motivation for participation included patients' expectations of physical benefits and the security of having professionals present. Patients experienced physical and emotional benefits and affirmed their social identity. Barriers were primarily related to side effects of chemotherapy.

CONCLUSION

The exercise intervention was undertaken safely by operable lung cancer patients initiated 2 weeks after surgery. The intervention put the patients on track to a healthier lifestyle regarding physical activity and smoking. The study indicates that exercise initiated early in the treatment trajectory is beneficial for operable lung cancer patients and especially for those who were physically active and motivated pre-illness and who did not experience side effect of treatment.

Exercise-induced lung cancer regression: mechanistic findings from a mouse model

BACKGROUND

It has been demonstrated that regular exercise improves the quality of life in patients undergoing treatment for lung cancer and has been associated with reductions in cancer-specific mortality in patients with colon and breast cancer. The direct effects of cardiovascular exercise on lung cancer tumor biology, however, remain unknown. The authors evaluated the effects of cardiovascular exercise in a mouse model of lung adenocarcinoma.

METHODS

Luciferase-tagged A549 lung adenocarcinoma cells were injected through the tail vein of nude male mice. Then, the mice underwent weekly bioluminescent imaging until lung tumors were clearly identified. After lung tumors were identified, the mice were randomized to daily wheel running versus no wheel running, and they were imaged weekly. After 4 weeks, all mice were killed, and the lung tumors were harvested. Western blot and immunohistochemical analyses were conducted on tumor tissues to identify potential differences in protein expression levels in exercising mice versus sedentary mice.

RESULTS

Lung tumors in exercising mice grew significantly more slowly relative to sedentary mice. There was no change in the development of metastatic lesions between the 2 groups. Protein analysis by Western blot or immunohistochemical analysis demonstrated increased p53 protein levels in exercising mice relative to sedentary mice as well as increased mediators of apoptosis, including Bax and active caspase 3, in tumor tissues. In both groups of mice, no normal tissue toxicity was observed in other organs.

CONCLUSIONS

Daily cardiovascular exercise appears to mitigate the growth of lung adenocarcinoma tumors, possibly by activation of the p53 tumor suppressor function and increased apoptosis.
