Symptoms of advanced cancer in palliative medicine: a longitudinal study

OBJECTIVES

This study aimed to examine the symptomatology of patients with advanced cancer at admittance to palliative care services and to investigate how the symptomatology changed during the first month, and whether these changes were associated with various patient characteristics.

METHODS

In a longitudinal study in Chile, outpatients with advanced cancer completed the questionnaires European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 Palliative Care and the Hospital Anxiety and Depression Scale. Prevalence and severity of symptoms and problems (S/Ps) at baseline were calculated. Differences in S/P scores from baseline to follow-up were calculated overall and according to patient characteristics. Multiple linear regression was used to study the associations between patient characteristics and changes in S/P scores.

RESULTS

At baseline, 201 patients answered the questionnaires and 177 completed the follow-up. Fatigue, pain and sleeping difficulties were the most prevalent S/Ps reported, and also had the highest mean scores at baseline. S/P scores at baseline varied significantly according to sex, age, civil status, residence, children, prior and current antineoplastic treatment. Emotional functioning, pain, sleeping difficulties, constipation and anxiety improved significantly during the first month of palliative care. Residence, cohabitation status, diagnosis and current antineoplastic treatment were associated with changes in S/P scores.

CONCLUSIONS

Patients reported moderate-to-severe levels of S/Ps at admittance to palliative care. Several S/Ps improved the first month. Certain patient characteristics were associated with changes in S/P scores. This information may guide clinicians to more effective interventions that can improve the quality of life of patients receiving palliative care.

Factors associated with palliative care symptoms in cancer patients in Palestine

Palliative care is critical to redundancy in cancer patients seeking to improve their quality of life. Evaluation should be incorporated into clinical practice routines at all stages of cancer. The Edmonton Symptom Assessment System (ESAS) was used to rate the intensity of ten symptom evaluations designed and validated for cancer patients in various languages and cultures. Therefore, the study aims to assess the symptoms reported using ESAS scores to identify patients who would benefit from palliative care that can improve the integration of palliative care into standard cancer care at An-Najah National University Hospital (NNUH). A cross-sectional study was selected for 271 cancer patients using a convenience sampling method at NNUH. Demographic, clinical, and lifestyle characteristics are described. Furthermore, patients' moderate to severe symptoms (score > 4) were obtained using ESAS-R. The survey consisted of 271 patients, with a response rate of 95%. The average age of the patients was 47 ± 17.7 years, ranging from 18 to 84 years. The male-to-female ratio was approximately 1:1, 59.4% of the patients were outpatients, and 153 (56.5%) had hematologic malignancies. Fatigue (62.7%) and drowsiness (61.6%) were the most common moderate to severe symptoms in ESAS. Furthermore, pain (54.6%), nausea (40.2%), lack of appetite (55.0%), shortness of breath (28.5%), depression (40.6%), anxiety (47.2%) and poor well-being (56.5%) were reported. In conclusion, fatigue and drowsiness were the most reported symptoms according to the ESAS scale among cancer patients, while moderate to severe symptoms were reported in cancer patients using the ESAS. The ESAS is a functional tool for assessing cancer patients' symptoms and establishing palliative care services.

Nausea at the start of specialized palliative care and change in nausea after the first weeks of palliative care were associated with cancer site, gender, and type of palliative care service-a nationwide study

PURPOSE

Nausea is a common and distressful symptom among patients in palliative care, but little is known about possible socio-demographic and clinical patient characteristics associated with nausea at the start of palliative care and change after initiation of palliative care. The aim of this study was to investigate whether patient characteristics were associated with nausea at the start of palliative care and with change in nausea during the first weeks of palliative care, respectively.

METHODS

Data was obtained from the nationwide Danish Palliative Care Database. The study included adult cancer patients who were admitted to palliative care and died between June 2016 and December 2020 and reported nausea level at the start of palliative care and possibly 1-4 weeks later. The associations between patient characteristics and nausea at the start of palliative care and change in nausea during palliative care, respectively, were studied using multiple regression analyses.

RESULTS

Nausea level was reported at the start of palliative care by 23,751 patients of whom 8037 also reported 1-4 weeks later. Higher nausea levels were found for women, patients with stomach or ovarian cancer, and inpatients at the start of palliative care. In multivariate analyses, cancer site was the variable most strongly associated with nausea change; the smallest nausea reductions were seen for myelomatosis and no reduction was seen for stomach cancer.

CONCLUSION

This study identified subgroups with the highest initial nausea level and those with the least nausea reduction after 1-4 weeks of palliative care. These latter findings should be considered in the initial treatment plan.

Longitudinal patient-reported outcomes and survival among early-stage non-small cell lung cancer patients receiving stereotactic body radiotherapy

BACKGROUND AND PURPOSE

The study objective was to determine whether longitudinal changes in patient-reported outcomes (PROs) were associated with survival among early-stage, non-small cell lung cancer (NSCLC) patients undergoing stereotactic body radiation therapy (SBRT).

MATERIALS AND METHODS

Data were obtained from January 2015 through March 2020. We ran a joint probability model to assess the relationship between time-to-death, and longitudinal PRO measurements. PROs were measured through the Edmonton Symptom Assessment Scale (ESAS). We controlled for other covariates likely to affect symptom burden and survival including stage, tumor diameter, comorbidities, gender, race/ethnicity, relationship status, age, and smoking status.

RESULTS

The sample included 510 early-stage NSCLC patients undergoing SBRT. The median age was 73.8 (range: 46.3-94.6). The survival component of the joint model demonstrates that longitudinal changes in ESAS scores are significantly associated with worse survival (HR: 1.04; 95% CI: 1.02-1.05). This finding suggests a one-unit increase in ESAS score increased probability of death by 4%. Other factors significantly associated with worse survival included older age (HR: 1.04; 95% CI: 1.03-1.05), larger tumor diameter (HR: 1.21; 95% CI: 1.01-1.46), male gender (HR: 1.87; 95% CI: 1.36-2.57), and current smoking status (HR: 2.39; 95% CI: 1.25-4.56).

CONCLUSION

PROs are increasingly being collected as a part of routine care delivery to improve symptom management. Healthcare systems can integrate these data with other real-world data to predict patient outcomes, such as survival. Capturing longitudinal PROs-in addition to PROs at diagnosis-may add prognostic value for estimating survival among early-stage NSCLC patients undergoing SBRT.

A cross-sectional gender-sensitive analysis of depressive symptoms in patients with advanced cancer

BACKGROUND

Patients with advanced cancer commonly report depressive symptoms. Examinations of gender differences in depressive symptoms in patients with advanced cancer have yielded inconsistent findings.

AIM

The objective of this study was to investigate whether the severity and correlates of depressive symptoms differ by gender in patients with advanced cancer.

DESIGN

Participants completed measures assessing sociodemographic and medical characteristics, disease burden, and psychosocial factors. Depressive symptoms were examined using the Patient Health Questionnaire, and other measures included physical functioning, symptom burden, general anxiety, death related distress, and dimensions of demoralization. A cross-sectional analysis examined the univariate and multivariate relationships between gender and depressive symptoms, while controlling for important covariates in multivariate analyses.

SETTING/PARTICIPANTS

Patients with advanced cancer (N = 305, 40% males and 60% females) were recruited for a psychotherapy trial from outpatient oncology clinics at a comprehensive cancer center in Canada.

RESULTS

Severity of depressive symptoms was similar for males (M = 7.09, SD = 4.59) and females (M = 7.66, SD = 5.01), t(303) = 1.01, p = 0.314. Greater general anxiety and number of cancer symptoms were associated with depressive symptoms in both males and females. Feeling like a failure (β = 0.192), less death anxiety (β = -0.188), severity of cancer symptoms (β = 0.166), and older age (β = 0.161) were associated with depressive symptoms only in males, while disheartenment (β = 0.216) and worse physical functioning (β = 0.275), were associated with depressive symptoms only in females.

CONCLUSIONS

Males and females report similar levels of depressive symptoms but the pathways to depression may differ by gender. These differences suggest the potential for gender-based preventive and therapeutic interventions in this population.

Sex-specific and gender-specific aspects in patient-reported outcomes

Patient-reported outcomes (PROs) are important tools in patient-centred medicine and allow for individual assessment of symptom burden and aspects of patients’ quality of life. While sex and gender differences have emerged in preclinical and clinical medicine, these differences are not adequately represented in the development and use of patient-reported outcome measures. However, even in personalised approaches, undesirable biases may occur when samples are unbalanced for certain characteristics, such as sex or gender. This review summarises the current status of the literature and trends in PROs with a focus on sex and gender aspects.

Associations of baseline patient-reported outcomes with treatment outcomes in advanced gastrointestinal cancer

BACKGROUND

Patient-reported outcomes (PROs) assessing quality of life (QOL) and symptom burden correlate with clinical outcomes in patients with cancer. However, to the authors' knowledge, data regarding associations between PROs and treatment response are lacking.

METHODS

The authors prospectively approached consecutive patients with advanced gastrointestinal cancer who were initiating a new treatment. Prior to treatment, patients reported their QOL (Functional Assessment of Cancer Therapy-General [FACT-G], 4 subscales: Functional, Physical, Emotional, Social; higher scores indicate better QOL) and symptom burden (Edmonton Symptom Assessment System [ESAS], Patient Health Questionnaire-4 [PHQ-4]; higher scores represent greater symptoms). Regression models were used to examine associations of baseline PROs with treatment response (clinical benefit or progressive disease [PD] at time of first scan), healthcare utilization, and survival.

RESULTS

From May 2019 to April 2020, a total of 112 patients with advanced gastrointestinal cancer were enrolled. For treatment response, 64.3% had CB and 35.7% had PD. Higher baseline ESAS-Physical (odds ratio, 1.04; P = .027) and lower FACT-G Functional (odds ratio, 0.92; P = .038) scores were associated with PD. Higher ESAS-Physical (hazard ratio [HR], 1.03; P = .044) and lower FACT-G Total (HR, 0.96; P = .005), FACT-G Physical (HR, 0.89; P < .001), and FACT-G Functional (HR, 0.87; P < .001) scores were associated with a greater hospitalization risk. Lower FACT-G Total (HR, 0.96; P = .009) and FACT-G Emotional (HR, 0.86; P = .012) scores as well as higher ESAS-Total (HR, 1.03; P = .014) and ESAS-Physical (HR, 1.04; P = .032) scores were associated with worse survival.

CONCLUSIONS

Baseline PROs are associated with treatment response in patients with advanced gastrointestinal cancer, namely physical symptoms and functional QOL, in addition to health care use and survival. The findings of the current study support the association between PROs and important clinical outcomes, including the novel finding of treatment response.

Exploring the gender dimension of problems and needs of patients receiving specialist palliative care in a German palliative care unit - the perspectives of patients and healthcare professionals

Background

Gender disparities of specific symptoms and problems have frequently been observed in palliative care patients, but research rarely focused on the range of problems and needs affected by gender.

Methods

We conducted semi-structured interviews with patients and healthcare professionals (HCPs) of a hospital-based palliative care unit to examine gender effects on patients’ problems and needs based on systematically gathered qualitative data. Content analysis was used to identify emerging themes with data coded using MAXQDA.

Results

Ten patients (5 female, 5 male) and 17 HCPs (12 female, 5 male) were interviewed. Seven categories of gender-specific problems and needs emerged: “physical symptoms, care and body image”, “psychological symptoms and emotional response”, “interaction with the palliative care team”, “use of professional supportive measures”, “activation of informal social networks”, “decision-making”, and “preservation of autonomy and identity”. Both patients and HCPs felt that female patients adopt more expressive coping strategies, have stronger need for communication with and support of HCPs, and activate an extended social network for support and decision-making. Further, both groups thought that male patients mainly rely on social support from partners, have higher expectations to be cared for at home, and have higher need for preservation of autonomy.

Conclusion

Gender relevantly impacts patients’ problems and needs during palliative care. Therefore, gender-sensitive palliative care that acknowledges the patient’s individual situation and respective ramifications are required.

Is Performance Status Associated with Symptom Scores?

Background: Symptom scores and performance status are both important measures for patients with cancer. However, since performance status is not often part of routinely collected data, there is interest in exploring whether it can be calculated from symptom scores. Methods: This was a population-based longitudinal study of cancer outpatients in Ontario, Canada in the year following their cancer diagnosis and among the subset of patients during the last year of their lives. Results: In the first year after diagnosis, there was a significant relationship between performance status and fatigue and appetite; fatigue and well-being had a significant association with performance status in the last year of life. In both periods, the associations, although statistically significant, were not large enough to be clinically meaningful. Conclusion: Performance status is an important measurement that cannot be substituted or captured with symptom scores; it is important for healthcare providers to record performance scores on a regular basis.

Symptoms of posttraumatic stress disorder among hospitalized patients with cancer

BACKGROUND

Patients with cancer experience many stressors placing them at risk for posttraumatic stress disorder (PTSD) symptoms, yet little is known about factors associated with PTSD symptoms in this population. This study explored relationships among patients' PTSD symptoms, physical and psychological symptom burden, and risk for hospital readmissions.

METHODS

We prospectively enrolled patients with cancer admitted for an unplanned hospitalization from August 2015-April 2017. Upon admission, we assessed patients' PTSD symptoms (Primary Care PTSD Screen), as well as physical (Edmonton Symptom Assessment System [ESAS]) and psychological (Patient Health Questionnaire 4 [PHQ-4]) symptoms. We examined associations between PTSD symptoms and patients' physical and psychological symptom burden using linear regression. We evaluated relationships between PTSD symptoms and unplanned hospital readmissions within 90-days using Cox regression.

RESULTS

We enrolled 954 of 1,087 (87.8%) patients approached, and 127 (13.3%) screened positive for PTSD symptoms. The 90-day hospital readmission rate was 38.9%. Younger age, female sex, greater comorbidities, and genitourinary cancer type were associated with higher PTSD scores. Patients' PTSD symptoms were associated with physical symptoms (ESAS physical: B = 3.41; P < .001), the total symptom burden (ESAS total: B = 5.97; P < .001), depression (PHQ-4 depression: B = 0.67; P < .001), and anxiety symptoms (PHQ-4 anxiety: B = 0.71; P < .001). Patients' PTSD symptoms were associated with a lower risk of hospital readmissions (hazard ratio, 0.81; P = .001).

CONCLUSIONS

A high proportion of hospitalized patients with cancer experience PTSD symptoms, which are associated with a greater physical and psychological symptom burden and a lower risk of hospital readmissions. Interventions to address patients' PTSD symptoms are needed and should account for their physical and psychological symptom burden. Cancer 2018. © 2018 American Cancer Society.

Factors associated with discharge disposition on an acute palliative care unit

PURPOSE

Acute palliative care units (APCUs) admit patients with cancer for symptom control, transition to community palliative care units or hospice (CPCU/H), or end-of-life care. Prognostication early in the course of admission is crucial for decision-making. We retrospectively evaluated factors associated with patients' discharge disposition on an APCU in a cancer center.

METHODS

We evaluated demographic, administrative, and clinical data for all patients admitted to the APCU in 2015. Clinical data included cancer diagnosis, delirium screening, and Edmonton Symptom Assessment System (ESAS) symptoms. An ESAS sub-score composed of fatigue, drowsiness, shortness of breath, and appetite (FDSA) was also investigated. Factors associated with patients' discharge disposition (home, CPCU/H, died on APCU) were identified using three-level multinomial logistic regression.

RESULTS

Among 280 patients, the median age was 65.5 and median length of stay was 10 days; 155 (55.4%) were admitted for symptom control, 65 (23.2%) for transition to CPCU/H, and 60 (21.4%) for terminal care. Discharge dispositions were as follows: 156 (55.7%) died, 63 (22.5%) returned home, and 61 (21.8%) were transferred to CPCU/H. On multivariable analysis, patients who died were less likely to be older (OR 0.97, p = 0.01), or to be admitted for symptom control (OR 0.06, p < 0.0001), and more likely to have a higher FDSA score 21-40 (OR 3.02, p = 0.004). Patients discharged to CPCU/H were less likely to have been admitted for symptom control (OR 0.06, p < 0.0001).

CONCLUSION

Age, reason for admission, and the FDSA symptom cluster on admission are variables that can inform clinicians about probable discharge disposition on an APCU.

Symptom Clusters and Quality of Life in Hospice Patients with Cancer

Background: Symptom control is an important part of palliative care and important to achieve optimal quality of life (QOL). Studies have shown that patients with advanced cancer suffer from diverse and often severe physical and psychological symptoms. The aim is to explore the influence of symptom clusters on QOL among patients with advanced cancer. Materials and Methods: 709 patients with advanced cancer were recruited to participate in a clinical trial focusing on symptom management and QOL. Patients were adults newly admitted to hospice home care in one of two hospices in southwest Florida, who could pass mental status screening. The instruments used for data collection were the Demographic Data Form, Memorial Symptom Assessment Scale (MSAS), and the Hospice Quality of Life Index-14. Results: Exploratory factor analysis and multiple regression were used to identify symptom clusters and their influence on QOL. The results revealed that the participants experienced multiple concurrent symptoms. There were four symptom clusters found among these cancer patients. Individual symptom distress scores that were the strongest predictors of QOL were: feeling pain; dry mouth; feeling drowsy; nausea; difficulty swallowing; worrying and feeling nervous. Conclusions: Patients with advanced cancer reported various concurrent symptoms, and these form symptom clusters of four main categories. The four symptoms clusters have a negative influence on patients’ QOL and required specific care from different members of the hospice healthcare team. The results of this study should be used to guide health care providers’ symptom management. Proper attention to symptom clusters should be the basis for accurate planning of effective interventions to manage the symptom clusters experienced by advanced cancer patients. The health care provider needs to plan ahead for these symptoms and manage any concurrent symptoms for successful promotion of their patient’s QOL.

Minimal Clinically Important Difference in the Physical, Emotional, and Total Symptom Distress Scores of the Edmonton Symptom Assessment System

CONTEXT

The Edmonton Symptom Assessment System (ESAS) is one of the most commonly used symptom batteries in clinical practice and research.

OBJECTIVES

We used the anchor-based approach to identify the minimal clinically important difference (MCID) for improvement and deterioration for ESAS physical, emotional, and total symptom distress scores.

METHODS

In this multicenter prospective study, we asked patients with advanced cancer to complete their ESAS at the first clinic visit and at a second visit three weeks later. The anchor for MCID determination was Patient's Global Impression regarding their physical, emotional, and overall symptom burden ("better," "about the same," or "worse"). We identified the optimal sensitivity/specificity cutoffs for both improvement and deterioration for the three ESAS scores and also determined the within-patient changes.

RESULTS

A total of 796 patients were enrolled from six centers. The ESAS scores had moderate responsiveness, with area under the receiver operating characteristic curve between 0.69 and 0.76. Using the sensitivity-specificity approach, the optimal cutoffs for ESAS physical, emotional, and total symptom distress scores were ≥3/60, ≥2/20, and ≥3/90 for improvement, and ≤-4/60, ≤-1/20, and ≤-4/90 for deterioration, respectively. These cutoffs had moderate sensitivities (59%-68%) and specificities (62%-80%). The within-patient change approach revealed the MCID cutoffs for improvement/deterioration to be 3/-4.3 for the physical score, 2.4/-1.8 for the emotional score, and 5.7/-2.9 for the total symptom distress score.

CONCLUSION

We identified the MCIDs for physical, emotional, and total symptom distress scores, which have implications for interpretation of symptom response in clinical trials.

Repeated assessments of symptom severity improve predictions for risk of death among patients with cancer

CONTEXT

Although prior studies show the importance of self-reported symptom scores as predictors of cancer survival, most are based on scores recorded at a single point in time.

OBJECTIVES

To show that information on repeated assessments of symptom severity improves predictions for risk of death and to use updated symptom information for determining whether worsening of symptom scores is associated with a higher hazard of death.

METHODS

This was a province-based longitudinal study of adult outpatients who had a cancer diagnosis and had assessments of symptom severity. We implemented a time-to-death Cox model with a time-varying covariate for each symptom to account for changing symptom scores over time. This model was compared with that using only a time-fixed (baseline) covariate for each symptom. The regression coefficients of each model were derived based on a randomly selected 60% of patients, and then, the predictive performance of each model was assessed via concordance probabilities when applied to the remaining 40% of patients.

RESULTS

This study had 66,112 patients diagnosed with cancer and more than 310,000 assessments of symptoms. The use of repeated assessments of symptom scores improved predictions for risk of death compared with using only baseline symptom scores. Increased pain and fatigue and reduced appetite were the strongest predictors for death.

CONCLUSION

If available, researchers should consider including changing information on symptom scores, as opposed to only baseline information on symptom scores, when examining hazard of death among patients with cancer. Worsening of pain, fatigue, and appetite may be a flag for impending death.

Sexual activity and body image: examining gender variability and the influence of psychological distress in cancer patients

Psychosocial factors impacting on the overall quality of life for cancer patients may differ between men and women. This study examined the influence that psychological distress, clinical, and social variables have on sexual activity and body image in adult oncology patients. Symptom data was collected from the Memorial Symptom Assessment Scale (MSAS). Analysis indicated women and patients with reported functional limitations were more likely to be less satisfied with how they looked. The final model showed that younger adults, Caucasians, those who were married and patients with some functional limitations were more likely to have problems with sexual interest/activity. Gender was not a significant predictor of having problems with sexual interest/activity. These results can be used by clinicians to identify patients who may be at an increased risk for negative body image and problems in sexual functioning. Further research regarding gender differences in cancer-related psychological symptoms is needed to assist healthcare professionals in providing comprehensive care while alleviating unresolved and interrelated health and psychosocial symptoms.

Comparing health-related quality of life of cancer patients under chemotherapy and of their caregivers

Introduction. Cancer is a major disorder physically and psychologically affecting both patients and their caregivers. In this study, health-related quality of life (HRQoL) of patient-caregiver dyads during the period of chemotherapy was assessed. Material and Methods. Two hundred twenty-two cancer patient-caregiver dyads were enrolled in the study, which was conducted from October 2008 to March 2009. HRQoL was evaluated with EQ-5D. Results. The mean age of the sample was 57.4 and 48.9 for patients and caregivers, respectively. The EQ-5D descriptive system indicates that female patients more frequently experience anxiety and depression than male patients. Male and higher-education caregivers had higher VAS scores, while demographic factors did not seem to influence patients' HRQoL. Anxiety and depression of caregivers were correlated with patients' problems in self-care and usual activities. Conclusions. Quality of life is highly influenced during the period of chemotherapy for both patients and caregivers and is often under reported. Interventions that can improve HRQoL, especially in the domain of mental health for both cancer patients and their caregivers, need to be implemented.

What does the answer mean? A qualitative study of how palliative cancer patients interpret and respond to the Edmonton Symptom Assessment System

The Edmonton Symptom Assessment System (ESAS) is a well-known self-reporting tool for symptom assessment in palliative care. Research has shown that patients experience difficulties in the scoring and interpretation, which may lead to suboptimal treatment. The aims were to examine how palliative care cancer patients interpreted and responded to the ESAS. Eleven patients (3 F/8 M), median age 65 (34-95) with mixed diagnoses were interviewed by means of cognitive interviewing, immediately after having completed the ESAS. The highest mean scores were found with tiredness (6.3) and oral dryness (5.7). The results showed that sources of error were related to interpretation of symptoms and differences in the understanding and use of the response format. The depression and anxiety symptoms were perceived as difficult to interpret, while the appetite item was particularly prone to misunderstandings. Contextual factors, such as mood and time of the day, influenced the answers. Lack of information and feedback from staff influenced the scores. Some patients stated that they scored at random because they did not understand why and how the ESAS was used. The patients' interpretation must be considered in order to minimize errors. The ESAS should always be reviewed with the patients after completion to improve symptom management, thereby strengthening the usability of the ESAS.

Gender differences in predicting quality of life in cancer patients with pain

PURPOSE

Numerous studies have identified several factors influencing quality of life (QOL) in cancer patients. However, studies on gender differences in cancer-related physical symptoms and QOL levels have yielded inconsistent results. The present study examined common symptoms (i.e., pain intensity, fatigue, and depression) in regard to their ability to predict QOL in male and female oncology patients with cancer pain.

METHOD

A total of 114 oncology outpatients, including 34 males and 80 females, with pain completed a demographic questionnaire, the Multidimensional Quality of Life Scale - Cancer, the Lee Fatigue Scale, the Center for Epidemiological Studies - Depression Scale, and a numeric rating scale for pain intensity.

RESULTS

The female patients reported significantly lower psychological dimension of QOL than their male counterparts (p=0.009). Also for the females, a negative correlation was found between pain intensity and QOL (r=-0.504, p<0.0001), as well as positive correlations between pain intensity and fatigue (r=0.421, p<0.0001) and depression (r=0.368, p<0.0001). Stepwise linear regression analyses showed that among the females, QOL was significantly predicted by pain intensity as well as by depression (F((2,75))=52.62, p<0.0001, Adj. R(2)=0.57). However, among the males, depression was the only symptom found to predict QOL (F((2,30))=9.72, p<0.001, Adj. R(2)=0.39).

CONCLUSION

Therefore, it is concluded that gender should be considered as an additional feature for further characterizing QOL. Gender differences in factors predicting QOL warrant different clinical approaches to male and female patients, and identifying these differences may assist health care providers in tailoring treatment modalities to individual patients for optimal outcomes.
