Comorbid chronic diseases and their associations with quality of life among gynecological cancer survivors

From Treatment to Recovery: Gynecological Survivors' and Caregivers' Perspectives About the Usability of an Educational Resource

The objective of this study was to understand gynecological cancer (GC) survivors' and their informal caregivers' perceptions about the usability of an educational resource to support their transition from primary cancer treatment into surveillance and/or recovery. After developing an empirical- and experiential-informed educational resource, we used a semi-structured questioning process to understand GC survivors and their caregivers' perceptions about its usability. Data were collected via online focus groups or 1:1 interviews that were audio recorded and transcribed. We used thematic analysis to analyze the data. Ten participants who were survivors or informal caregivers of cervical, ovarian, or uterine/endometrial cancer participated in two rounds of data collection. We grouped qualitative data into two themes: (1) reputable, relevant, and accessible education reduces uncertainty and promotes connection, and (2) individualized delivery of education provided by trusted cancer clinicians. The transition from treatment to surveillance is a challenging time for which reputable, relevant, and accessible educational resources are useful to facilitate an understanding about and self-management of survivorship-related concerns. Survivors and caregivers look to clinicians to provide reputable education to address their needs. This education should be diverse in content and referred to repeatedly throughout the cancer trajectory.

Unraveling the nutrition and health situation of adults in geographically isolated and disadvantaged areas (GIDA) and non-GIDA in the Philippines: A comparative study

Background: Geographically Isolated and Disadvantaged Areas (GIDA) are communities physically and socioeconomically separated from mainstream society (non-GIDA) and lack comprehensive nutrition and health assessments. Aim: This study aimed to assess the nutritional and health status and determine the factors associated with chronic energy deficiency (CED) and overweight/obesity among adults, 20-59 years old, residing in GIDA and non-GIDA. Methods: Data of the 20,381 adults collected in the Expanded National Nutrition Survey were analyzed. Multivariate logistic regression analyses were performed to determine the predictors of CED and overweight/obesity. Results: Chronic energy deficiency and current smoking were significantly higher in GIDA, while overweight/obesity, alcohol consumption, elevated blood pressure, and insufficient physical activity were higher in non-GIDA (p < 0.001). Higher odds of CED was associated with food insecurity (adjusted odds ratio [AOR]: 1.5, p < 0.001; AOR: 1.3, p < 0.001) and current smoking (AOR: 1.4, p = 0.001; AOR: 1.3, p < 0.001) in both GIDA and non-GIDA while poor wealth (AOR: 1.5, p < 0.001) only in non-GIDA. Higher odds of overweight/obesity was associated with higher age ≥30 years (AOR: 2.1, p < 0.001; AOR: 1.9, p < 0.001), being female (AOR: 1.7, p < 0.001; AOR: 1.3, p < 0.001), with grade level completed (AOR: 1.7, p = 0.004; AOR: 1.2, p = 0.038), urban residence (AOR: 1.2, p = 0.035; AOR: 1.3, p < 0.001), hypertension (AOR: 2.4, p < 0.001; AOR: 2.3, p < 0.001), and insufficient physical activity (AOR: 1.1, p = 0.020; AOR: 1.1, p = 0.027) in both GIDA and non-GIDA. Conclusions: Malnutrition affects GIDA in almost the same magnitude. The double burden of malnutrition and health inequity in GIDA underscores the greater need for comprehensive policies and stronger programs directed toward underserved areas.

The relationship of chronic disease conditions to mental and physical health among cancer survivors

PURPOSE

This study examined the relationship between the presence of chronic disease conditions and mental and physical health among cancer survivors in the United States.

METHODS

We conducted a cross-sectional analysis utilizing survey data from the 2016-2017 Behavioral Risk Factor Surveillance System (BRFSS) on 65,673 eligible cancer survivors. The primary outcomes of interest were self-rated metal/physical health in the past 30 days. Descriptive statistics and multivariate logistic regression were used to examine the mentioned association.

RESULTS

15.3% and 24.8% of survivors reported having several days of poor mental and physical health (14-30 days compared to 0-13 days), and 42.4% of survivors reported having one to two chronic diseases. In multivariate analysis, survivors with one to two chronic diseases were more likely to report several days of poor mental (OR, 2.74; 95% CI, 2.22-3.38) and physical (OR, 1.95; 95% CI, 1.72-2.22) health. Survivors with 3+ chronic diseases had markedly higher odds of having several days of poor mental (OR, 6.41; 95% CI, 5.19-7.91) and physical health (OR, 4.71; 95% CI, 4.16-5.34). Among survivors with at least one chronic disease, older age, insured, and more perceived social/emotional support were negatively associated with mental health (p value <0.05). Similarly, older age was related to fewer days of poor physical health (p value <0.05) regardless of chronic disease conditions.

CONCLUSION

Having chronic diseases was associated with more days of poor mental and physical health among cancer survivors. Integrated, extensive care should include mental/physical health components and chronic disease management in cancer survivorship care.

Quality of Life and Associated Factors Among Adult Cancer Patients Undergoing Chemotherapy Treatment at Amhara National, Regional State, Ethiopia, 2021

Background

In cancer, quality of life (QoL) is an important patient-reported metric; evaluating how patients feel physically and emotionally while fighting the disease could lead to better treatment. Despite its therapeutic effects, chemotherapy treatment causes a plethora of side effects that can affect QoL. Factors affecting the QoL of cancer patients undergoing chemotherapy treatment in Ethiopia have not been thoroughly investigated. As a result, this study assesses QoL and associated characteristics among adult cancer patients receiving chemotherapy at Amhara Region, Ethiopia in 2021.

Martials and Methods

From February 15 to May 15, 2021, an institutional based cross-sectional study was done in Amhara region. Three hundred fourteen patients were included in the study. The data was gathered using Amharic version of European organization for research and treatment of cancer quality of life questionnaire (EORTC QLQ C-30) through a face-to-face interview. Epi Data 4.6 was used to enter the data, which was then exported to SPSS version 23 for statistical analysis. Multivariable logistic regression analysis was used to determine the relationship between independent and dependent variables. The statistical significance was determined by a p-value of less than .05.

Result

Cancer patients in Amhara Region had a 44.32 average QoL. Emotional functioning AOR 1.01 (1.0-1.04), social functioning AOR 1.02 (1.01-1.03), nausea and vomiting AOR 0.95 (0.93-0.98), pain AOR 0.95 (0.93-0.98), financial difficulty 0.97 (0.95-0.99), education AOR 4.3 (1.49-12.32), underweight AOR 0.45 (0.24-0.84),  > 5th cycle of chemotherapy AOR 4 (1.78-9.11), stage IV cancer AOR 0.21 (0.06-0.71), comorbidity AOR 0.28 (0.14-0.57), anxiety AOR 0.32 (0.12-0.84), and depression AOR 0.29 (0.13-0.63) were all significantly associated with QoL in multivariable logistic regression.

Conclusion

Adult cancer patients receiving chemotherapy in the Amhara region had a poor QoL. Emotional functioning, social functioning, nausea and vomiting, pain, financial difficulty, education, body mass index, cancer stage, chemotherapy cycle, comorbidity, anxiety, and depression all had association with QoL. To improve the QoL of cancer patients, QoL assessments, proper symptom management, nutritional support, and integration of psycho-oncology treatment should be considered.

The association between physical activity, sedentary time and health-related quality of life in cancer survivors

Background

Although physical activity (PA) and sedentary time in cancer survivors (CSs) were associated with health-related quality of life (HRQOL), it was not clear whether their associations were similar among CSs with different number of comorbid chronic diseases (CCDs). This study aimed to investigate the associations between PA, sedentary time and HRQOL in CSs with different number of CCDs.

Methods

A cross-sectional study was conducted among 1546 CSs between June and September 2018 in Shanghai, China. Data were collected with a self-reported questionnaire including sociodemographic characteristics, CCDs, PA, sedentary time and HRQOL. International Physical Activity Questionnaire and Cancer Quality of Life Questionnaire-Core30 were respectively used to measure PA and HRQOL of CSs. Associations of PA and sedentary time with HRQOL among CSs with different number of CCDs were evaluated by using logistic regression, adjusted for confounding factors.

Results

About seventy-five percent CSs had at least one CCD. Approximately three fifths CSs had high PA level and < 4 h/day sedentary time. Moderate PA level and high PA level were shown to be associated with better HRQOL among all participants. In CSs with ≤ 2 CCDs, high PA level was significantly associated with higher scores of physical function and lower scores of nausea and vomiting, appetite loss. However, there was a positive association between high PA level and constipation score among CSs with ≥ 3 CCDs. CSs with shorter sedentary time had better HRQOL in those with CCDs.

Conclusions

High PA level and long sedentary time have significant association with worse HRQOL of CSs with ≥ 3 CCDs, while high PA level is positively associated with HRQOL in CSs with ≤ 2 CCDs. Our findings may support further studies of the causal association between PA, sedentary times and HRQOL to provide targeted proposal to improve the HRQOL of CSs according to their number of CCDs.

Associations between multimorbidity and depression among breast cancer survivors within the UK Biobank cohort: a cross-sectional study

BACKGROUND

Advances in the early detection of cancer and its treatment have resulted in an increasing number of people living with and beyond breast cancer. Multimorbidity is also becoming more common in this population as more people live longer with breast cancer and experience late effects of cancer treatment. Breast cancer survivors have heightened risk of depression, but to what extent multimorbidity affects the mental health of this population is less clear. This study aims to investigate the association between multimorbidity and depression among women living with and beyond breast cancer in the UK Biobank cohort.

METHODS

Data from UK Biobank (recruitment during 2006 to 2010, aged 40-70 years) were used to identify 8438 women with a previous diagnosis of breast cancer via linked cancer registries in England, Scotland and Wales. The lifetime number of chronic conditions was self-reported and multimorbidity defined as 0, 1, 2, 3, 4 or 5+. The Patient Health Questionnaire (PHQ-2) was used to define participants that were likely to have depression based on their symptom reporting at baseline. Logistic regression models were used to analyse the associations between multimorbidity and depression, accounting for a number of potential sociodemographic confounding variables (including age, ethnicity, socioeconomic deprivation, education level and marital status) and characteristics related to the cancer (number of years since diagnosis and recurrence/secondary cancer).

RESULTS

Multimorbidity was common among breast cancer survivors, with 32.9% of women experiencing one and 30.1% experiencing two or more chronic health conditions. Hypertension (25.8%), painful conditions (18.3%), and asthma (11.6%) were the three most common co-morbid conditions. 5.3% of participants had current depression. A strong, dose-response relationship was found between multimorbidity and the likelihood of depression (OR = 2.09, 95% CI: 1.56-2.79 for two conditions and OR = 6.06, 95% CI: 3.63-10.14 for five or more conditions).

CONCLUSIONS

Multimorbidity and depression were strongly associated among female UK Biobank participants with a previous breast cancer diagnosis. This association became increasingly pronounced as the number of chronic comorbid conditions increased. As more people survive cancer for longer, increasing recognition and support for multimorbidity and its impact on mental health is needed.

Factors of sexual quality of life in gynaecological cancers: a systematic literature review

Background

The impact of cancer diagnosis and treatment on sexual quality of life (SQoL) is a well-established survivorship issue for gynaecological cancer survivors (GCS), yet little is known on how to intervene.

Purpose

The aim of this systematic review was to identify the factors explaining the variability in SQoL for GCS.

Methods

We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework and the software Covidence. Electronic databases Scopus, Web of Science, PUBMED and CINAHL were searched for original research on GCS published between 2002 and 2018. We performed a two-stage screening process against selection criteria and quality assessment of individual studies. The Salutogenic Theory and the PRECEDE–PROCEED model were used as theoretical frameworks to identify and categorise factors.

Results

The initial search yielded 3,505 articles resulting in a total of 46 studies used to examine the association between factors of SQoL and gynaecological cancers. Our findings suggested that SQoL varies across subgroups based on age, menopausal status, relationship status, and treatment modality. Protective factors included clinicians’ knowledge and confidence, preventive medical approach, risk and needs assessment, patient–clinician communication, relationship quality, psychosocial support, symptom management, accessibility of psychosexual care, and self-efficacy in the rediscovery of sexuality.

Conclusion

Despite the high incidence and long-term impact of sexual health issues on quality of life, supportive care needs are not being met. A better understanding of the evidence base around the factors of SQoL can help health professionals take steps to protect and improve SQoL in GCS.

Examination of individual and multiple comorbid conditions and health-related quality of life in older cancer survivors

PURPOSE

Older cancer survivors (≥ 65 years at diagnosis) are at high-risk for multimorbidity (2 + comorbid conditions). However, few studies have utilized a generalizable sample of older cancer survivors to understand how individual comorbid conditions, as opposed to total comorbidity burden, are associated with health-related quality of life (HRQOL). We examined associations between HRQOL outcomes (pain, fatigue, physical function), individual comorbidities (cardiovascular disease [CVD], lung disease, diabetes, arthritis) and total comorbidity (cancer-only, cancer + 1 condition, cancer + 2 or more conditions).

METHODS

Utilizing a population-based sample of 2019 older cancer survivors, we tested associations between comorbid conditions and the HRQOL outcomes using generalized linear models. HRQOL domains were assessed using Patient-Reported Outcome Measurement Information System^® (PROMIS^®) measures. Comorbidity was assessed via self-report.

RESULTS

Cancer survivors with lung disease reported significantly worse physical functioning (β = - 4.96, p < 0.001), survivors with arthritis reported significantly higher pain (β = 4.37, p < 0.001), and survivors with CVD reported significantly higher fatigue (β = 3.45, p < 0.001) compared to survivors without each condition. Having cancer + 1 condition was not as strongly associated with all outcomes as when individual conditions were tested (e.g. pain: β = 3.09, p < 0.001). Having 2+ comorbidities had a stronger association with all outcomes (e.g. physical function: β = - 7.51, p < 0.001) than examining conditions individually.

CONCLUSIONS

Knowing the specific comorbid condition profile of an older cancer survivor provides insight into specific HRQOL outcomes that may be impaired in cancer survivorship, but understanding total comorbidity burden, regardless of the specific conditions, sheds light on survivors at-risk for multiple impairments in HRQOL. This information, taken together, can inform risk-stratified survivorship care.

Prospective Analysis of Health-Related Quality of Life in Older Adults With Cancer

OBJECTIVE

The aim of the present study was to evaluate health-related quality of life (HRQoL) changes at 6 to 12 months after cancer diagnosis and to assess the impact of age in older adults with cancer.

METHODS

A cohort study using patients ≥60 years old diagnosed with cancer. Health-related quality of life scores were calculated according to the European Organisation for Research and Treatment of Cancer questionnaire. Student's t tests for paired samples and a binomial logistic regression were performed.

RESULTS

The study included 241 patients. At diagnosis, the affected HRQoL functions were physical and emotional functions, financial difficulties, pain, and insomnia. At follow-up, cognitive function (P < .001) and dyspnea (P = .004) worsened, while emotional function improved (P = .003).

DISCUSSION

At the 6 to 12 months of follow-up, older adult cancer patients showed worsening cognitive function and dyspnea and improved emotional function. These HRQoL changes were not associated with age.

Do age and comorbidity impair recovery during two years after treatment for endometrial cancer?

BACKGROUND

A better understanding of the impact of age and comorbidity on health-related quality of life (HRQoL) may improve treatment decision-making in patients with endometrial cancer. We investigated whether either age or comorbidity is more strongly associated with changes in HRQoL over time.

METHODS

Endometrial cancer patients (n = 296) were invited to complete questionnaires after initial treatment and after 6, 12 and 24 months follow-up. Patients were divided into subgroups according to age (<60, 60-75 and ≥75 years) and according to comorbidity (0, 1, 2 or ≥3). HRQoL was measured with the five EORTC QLQ-C30 functioning scales. Linear mixed models were performed for the different subgroups to assess changes in HRQoL over time. HRQoL was also compared to longitudinal outcomes from an age- and gender-matched normative population.

RESULTS

The first questionnaire was returned by 221 patients (75%) of whom six were excluded due to progressive disease. Changes in HRQoL were mainly associated with cumulative comorbidity burden and not with age. Patients with comorbidity reported deterioration of physical and role functioning between 12 and 24 months. Compared to the normative population, patients initially scored higher on physical and role functioning, but at 24 months outcomes were no longer different.

CONCLUSION

Cumulative comorbidity burden was more strongly associated with deterioration of HRQoL than patient's age. Therefore, patients with endometrial cancer and multiple comorbid conditions require careful follow-up of HRQoL after treatment.

Health status of middle-aged and older cancer survivors: a nationwide cross-sectional study from the China Health and Retirement Longitudinal Study (CHARLS)

Background

The number of Chinese cancer survivors has increased bolstered by the combined trends of an aging population and improved cancer survival; however, related research on cancer survivorship remains limited. Therefore, this study aimed to provide an overview of the health status of middle-aged and older cancer survivors in China.

Methods

We used the cross-sectional self-reported survey data from wave 4 in the China Health and Retirement Longitudinal Study (CHARLS). A total of 354 cancer survivors and 16,664 participants without cancer were identified from CHARLS. Physical and mental health, health behavior, and health care information collected by questionnaire were compared between these two groups.

Results

Compared with the general middle-aged and older population, cancer survivors had more concomitant chronic diseases (2.75 vs. 2.00, P<0.001). In addition, cancer survivors were found to be more statistically likely to have difficulties with activity (3.53 vs. 2.39, P<0.001) and have depressive symptoms (10.07 vs. 8.01, P<0.001) compared with participants without cancer. Also, cancer survivors were less likely to drink compared to those without a cancer diagnosis (OR 0.49; 95% CI, 0.36–0.66, P<0.001), but smoking behavior and physical activity did not show a significant difference. Coexisting chronic diseases and smoking harmed the physical and mental health of middle-aged and older people. We also found that cancer survivors had higher medical care expenses when compared with participants without cancer.

Conclusions

Cancer survivors older than 45 years in China have poorer outcomes in comorbidities and physical and mental health than their age-matched individual counterparts without cancer. Therefore, a higher quality and more cost-effective supportive care for these individuals is needed.

Comparative Study in Quality of Life between Thai Endometrial Cancer Survivors and Healthy Women in Thammasat University Hospital

Background:

This study aimed to survey quality of life (QoL) in endometrial cancer survivors between surgery with adjuvant therapy (radiation with or without chemotherapy) and surgery alone in Thammasat University Hospital, Thailand.

Materials and Methods:

This cross-sectional study was conducted at the Gynecologic Oncology clinic, Thammasat University hospital, Thailand between March 2011 and May 2019. Participants were endometrial cancer cases who underwent surgical staging with or without adjuvant treatment (study) and healthy women who came to gynecologic department for annual cervical screening (control). Assessment of QoL was investigated via the structural questionnaire designed by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 (Thai version).

Results:

During the period of the study, 94 participants who were diagnosed with endometrial cancer and underwent surgical staging were enrolled. There were 51, 43 and 51 cases in group A (surgery with adjuvant therapy), group B (surgery only) and group C (control), respectively. Control cases were participants who had comparable demographic characteristics and underwent gynecological checkup during the period of study. In part of physical functioning, group B had statistically better scores than group A. Participant in group B and C reported significantly better QoL in part of social functioning than group A. Symptom severity; appetite loss and constipation in group B was statistically less than in group A. Constipation problems in group A and C were comparable. Participants in group C had worse global health status than group A/B.

Conclusion:

Adjuvant treatment with either radiation or chemotherapy had negative impacts on QoL in endometrial cancer survivors. It impacted physical health, social function, appetite loss, and constipation. All endometrial cancer survivors had global health scores better than healthy peers. Thoroughly counseling to endometrial cancer survivors remains an important tool for increasing awareness of treatment complications and lowering psychological emotional stress.

Association between anxiety, depression, and comorbid chronic diseases among cancer survivors

OBJECTIVE

Cancer survivors (CSs) often face the dual physical burden of cancer and other comorbid chronic disease (CCD) and have a great deal of psychological distress, such as anxiety and depression. However, the association between CCD and psychological problems remain less clear in CS. This study was performed to investigate the prevalence of anxiety and depression in Chinese CS, and whether CCD have impact on CSs' anxiety and depression.

METHODS

A cross-sectional study was conducted among 1546 CSs in Shanghai, China. All participants were asked to complete a questionnaire containing Zung self-rating anxiety scale (SAS), Zung self-rating depression scale (SDS), and questions on sociodemographic characteristics and CCD. Associations between CCDs, and anxiety and depression, were evaluated by using logistic regression, adjusted for confounding factors.

RESULTS

The prevalence of anxiety and depression in CSs were 28.2 % and 48.2%, respectively. 74.9% CSs had one or more comorbidities. Almost all CCDs examined showed associations with anxiety, except for CSs with diabetes. CSs with hyperlipidemia, diabetes, heart and cardiovascular diseases, and musculoskeletal diseases had significantly greater depression scores. When compared with those without CCD, CSs with one to two CCDs and greater than or equal to three CCDs had higher risks of anxiety and depression.

CONCLUSIONS

Anxiety and depression were more prevalent among CSs who also had CCDs. CCD have significantly negative association with CSs' anxiety and depression. Further cohort research will help deduce the causal relationships between CCDs, and anxiety and depression.

The Safety and Feasibility of Gynecologic Cancer Surgery Combined With Surgery for Pelvic Floor Dysfunction

OBJECTIVES

Women with gynecologic cancer may also present with pelvic floor dysfunction that can have a significant effect on quality of life. Combined surgical intervention for both malignancy and pelvic floor dysfunction may improve quality of life with minimal additional risk. We sought to determine the safety, feasibility, and frequency of combined gynecologic cancer surgery and surgery for pelvic floor dysfunction.

METHODS

This is a retrospective cohort study that utilized the National Surgical Quality Improvement Program database provided through the American College of Surgeons. The National Surgical Quality Improvement Program database was queried for patients with a final diagnosis of gynecologic malignancy from 2011 to 2015. Common Procedural Terminology codes for gynecologic oncology procedures and pelvic floor dysfunction surgery were used to identify the study population. Baseline demographics and postoperative complications were abstracted from the database for these patients and compared for patients with combined surgeries versus gynecologic cancer surgeries alone.

RESULTS

One hundred twenty-nine women underwent combined procedures compared with 25,838 women undergoing gynecologic cancer surgery alone. Patients who underwent combined procedures were older, had lower body mass index, had higher preoperative albumin and hematocrit, and lower morbidity estimates (P < 0.05). Mean operative time was longer (226.4 vs 174.4 minutes, P < 0.01). There were no statistically significant differences in race, ethnicity, or medical comorbidities. There were no statistically significant differences in postoperative complications or readmissions between the 2 groups (P > 0.1).

CONCLUSIONS

Combined gynecologic cancer and pelvic floor dysfunction procedures are feasible and can safely be performed without differences in postoperative complications in appropriately selected patients.

Effects of lifestyle modification on cancer recurrence, overall survival and quality of life in gynaecological cancer survivors: A systematic review and meta-analysis

The benefits of lifestyle interventions for women who have survived gynaecological cancer (GC) remain unclear. This systematic review aimed to determine the effect of lifestyle interventions on cancer recurrence, overall survival and quality of life (QoL) in women with GC. We searched Medline, Embase, PsycINFO and EBM Reviews from June to July 2016 to identify relevant literature. We included randomized controlled trials in which a lifestyle intervention (diet, weight loss, physical activity and/or behavioural interventions) were compared with a control condition (usual care, placebo or other lifestyle interventions) in women who had survived endometrial or ovarian cancer. Primary outcomes included cancer recurrence and overall survival and the secondary outcome was QoL. Data extraction and risk-of-bias assessment were performed by two independent reviewers. A random-effects meta-analysis model was used to calculate mean differences (md) and 95% confidence intervals (CI). The literature search yielded 928 citations and three trials met the inclusion criteria. No randomized controlled trial assessed the effect of lifestyle interventions on cancer recurrence or survival. Meta-analysis of two randomized controlled trials on the effect of lifestyle interventions on total QoL at 3 or 6 months post-intervention showed no significant difference between intervention and control groups [(md; 1.60; 95% CI, -1.65 to 4.85) and (md; 2.07; 95% CI, -1.80 to 5.94), respectively]. That is, lifestyle intervention had no effect on overall QoL or individual QoL domains (physical, emotional, social wellbeing and fatigue) in GC survivors. Systematic review registration: PROSPERO CRD42016043719.

Quality of Life and Its Association with Physical Activity among Different Types of Cancer Survivors

Purpose

The main goal of this study was to compare the quality of life (QOL) and its association with physical activity (PA) among patients diagnosed with different types of cancer. Based on the results, we tentatively present suggestions for the cancer health care model.

Method

A cross-sectional study was conducted with 2915 cancer survivors recruited from multi-community cancer rehabilitation centers, all of which were affiliated with the Shanghai Cancer Rehabilitation Club. We collected data including socio-demographic characteristics and information about PA. All the subjects included were asked to complete the European Organization for Research and Treatment Quality of Life Questionnaires (EORTC QLQ-C30) and Functional Assessment of Cancer Therapy—General Questionnaire (FACT-G). Multiple linear regression models were employed to control the potential confounding factors.

Results

Lung cancer survivors reported the worst dyspnea. Colorectal cancer survivors claimed the highest level of constipation and diarrhea. Liver cancer survivors indicated greatest loss of appetite and financial difficulties. Generally, survivors with PA tended to reported better QOL, although these associations among liver cancer survivors were not statistically significant. Moreover, survivors of all cancer types who performed PA did not report significant lower level of constipation or diarrhea. The relationship between PA frequency and QOL among cancer survivors remained unexplored.

Conclusions

Both QOL and its association with PA vary among survivors of different cancer types. The detailed results can assist clinicians and public health practitioners with improving health care management.

The association between comorbidities and the quality of life among colorectal cancer survivors in the People's Republic of China

BACKGROUND

Cancer survivors with certain comorbidities had lower quality of life (QOL). This study was performed to investigate the prevalence of comorbidities and the association between comorbidities and the QOL among Chinese colorectal cancer survivors (CCS).

METHODS

A cross-sectional study was conducted among 1,398 CCS between April and July 2013 in Shanghai, People's Republic of China. All the participants were asked to complete a simplified Chinese version of the European Organization for Research and Treatment quality of life version 3 questionnaire and questions on sociodemographic characteristics and comorbidities. In order to mitigate the bias caused by confounding factors, multiple linear regression models were employed to calculate the adjusted means of QOL scores.

RESULTS

The proportion of participants without any comorbidity was only 20.2%. The CCS with comorbidities except hypertension scored significantly lower on the European Organization for Research and Treatment quality of life version 3 questionnaire global health and functioning scales and Functional Assessment of Cancer Therapy-General scales but higher on the European Organization for Research and Treatment quality of life version 3 questionnaire symptom scores, indicating that they had poorer QOL, particularly for cardiovascular, respiratory, digestive, and musculoskeletal diseases.

CONCLUSION

There exists a significant association between comorbidities and QOL among Chinese CCS, and participants with comorbidities generally reported lower QOL scores. These findings suggested comprehensive care for CCS.
