Pretreatment quality of life and survival in patients with lung cancer: a systematic review and meta-analysis.

BACKGROUND: Although many studies have explored the correlation between quality of life and survival, none have reported this relationship for specific cancers assessed at distinct time points. This meta-analysis aimed to investigate the impact of pretreatment Global Quality of Life (QOL) and functioning QOL, including physical, social, role, emotional, and cognitive QOLs, on mortality risk in patients with lung cancer. METHODS: A literature search was conducted across the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and PubMed databases for articles published between their inception and December 2022. Subsequently, 11 studies were selected based on predefined eligibility criteria to investigate the relationship between pretreatment QOLs and mortality risk in patients with lung cancer. RESULTS: Pretreatment global, physical, social, role, and emotional QOLs were significantly associated with mortality risk as follows: Global QOL (hazard ratio [HR] = 1.08 95% confidence interval [CI] = 1.03-1.13); Physical QOL (HR = 1.04 95% CI = 1.02-1.05); Social QOL (HR = 1.02 95% CI = 1.01-1.03; Role QOL (HR = 1.01 95% CI = 1.01-1.02); Emotional QOL (HR = 1.01 95% CI = 1.00-1.03). CONCLUSIONS: These findings underscore the importance of early QOL assessment after diagnosis as well as early provision of physical, social, and psychological support accommodating each patient's demands.

Global quality of life and mortality risk in patients with cancer: a systematic review and meta-analysis.

PURPOSE: This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment. METHODS: A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment. RESULTS: Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL. CONCLUSION: These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.

Impact of quality of life on mortality risk in patients with esophageal cancer: a systematic review and meta-analysis.

This systematic review and meta-analysis investigated the impact of quality of life (QoL) on mortality risk in patients with esophageal cancer. A literature search was conducted using the CINAHL, PubMed/MEDLINE, and Scopus databases for articles published from inception to December 2022. Observational studies that examined the association between QoL and mortality risk in patients with esophageal cancer were included. Subgroup analyses were performed for time points of QoL assessment and for types of treatment. Seven studies were included in the final analysis. Overall, global QoL was significantly associated with mortality risk (hazard ratio 1.02, 95% confidence interval 1.01-1.04; p < 0.00004). Among the QoL subscales of QoL, physical, emotional, role, cognitive, and social QoL were significantly associated with mortality risk. A subgroup analysis by timepoints of QoL assessment demonstrated that pre- and posttreatment global and physical, pretreatment role, and posttreatment cognitive QoL were significantly associated with mortality risk. Moreover, another subgroup analysis by types of treatment demonstrated that the role QoL in patients with surgery, and the global, physical, role, and social QoL in those with other treatments were significantly associated with mortality risk. These findings indicate that the assessment of QoL in patients with esophageal cancer before and after treatment not only provides information on patients' condition at the time of treatment but may also serve as an outcome for predicting life expectancy. Therefore, it is important to conduct regular QoL assessments and take a proactive approach to improve QoL based on the results of these assessments.

Association between quality of life and mortality risk in patients with breast cancer: a systematic review and meta-analysis.

BACKGROUND: Patients with breast cancer present with various problems that have an adverse effect on the quality of life (QOL). However, the association between the QOL and mortality among patients with breast cancer remains controversial. Therefore, this systematic review and meta-analysis aimed to determine whether QOL impacts prognosis in patients with breast cancer. METHODS: The databases of CINAHL, Scopus, and PubMed databases were searched to retrieve observational studies that assessed the QOL and mortality risk in patients with breast cancer published before December 2022. RESULTS: Among the 119,061 articles retrieved, six observational studies were included in the meta-analysis. Physical QOL (hazard ratio [HR]: 1.04, 95% confidence interval [CI]: 1.01-1.07, p = 0.003), emotional QOL (HR: 1.01, 95% CI: 1.00-1.03, p = 0.05), and role QOL (HR: 1.01, 95% CI: 1.00-1.01, p = 0.007) showed significant associations with mortality risk. In contrast, global QOL, cognitive QOL, and social QOL showed no associations with mortality risk. Subgroup analysis performed according to treatment time points revealed that the post-treatment physical QOL was associated with mortality risk. CONCLUSIONS: Physical QOL, emotional QOL, and role QOL are associated with mortality risk in patients with breast cancer. Furthermore, post-treatment physical QOL showed a more significant association with prolonged survival than pre-treatment physical QOL.
