Efficacy results and quality-of-life measures in men receiving sildenafil citrate for the treatment of erectile dysfunction

The aim of the present study was to evaluate the efficacy of sildenafil citrate and its effects on quality of life (QoL) in men with erectile dysfunction (ED) using data from three multicenter, double-blind, placebo-controlled clinical trials. Efficacy was evaluated using a global efficacy question (improvement of erections) and questions from the International Index of Erectile Function (IIEF) addressing the ability to achieve and maintain erections. QoL directly related to ED was evaluated using questions 13 and 14 of the IIEF, several psychometric instruments, and a questionnaire addressing men's concerns about their erection problems. Ninety-seven percent of patients receiving sildenafil reported improved erections compared with 23% of patients receiving placebo (p < 0.0001); also reported were improvements in the ability to achieve and maintain erections with sildenafil but not with placebo (p < 0.0001). Improvements were also seen for other aspects of sexual function (overall satisfaction with sex life, sexual relationships with partners, concerns about erectile problems; p < 0.0001) and general mental health (well-being, self-control, satisfaction with relationship, health relative to 1 year ago, mental health; p ≤ 0.05) following treatment with sildenafil. Thus, treatment of ED with sildenafil can significantly improve key QoL parameters related to sexual dysfunction and general mental health.

CLINICAL EFFICACY AND SAFETY OF SILDENAFIL IN ELDERLY PATIENTS WITH ERECTILE DYSFUNCTION

Erectile dysfunction (ED) is a common medical disorder affecting elderly men. Sildenafil citrate has been shown to be an effective and well-tolerated oral agent for treating ED in the general population of adult men with ED of broad-spectrum etiology. Elderly men are more likely to have concomitant medical problems than the general population of men with ED. In this study, we examined the efficacy and safety of sildenafil administration in elderly patients with ED. Forty-four elderly men with ED (≥60 years old) of broad-spectrum etiology were treated with 25?mg or 50?mg doses of sildenafil citrate. Age ranged from 60 to 78 years (65 ± 4.5; means ± S.D.). Mean follow-up period was 12.3 ± 6.5 months, with a range of 1 to 25 months. Primary efficacy assessments were performed using the International Index of Erectile Function 5 (IIEF5) before their first dose of sildenafil and after at least 4 weeks of therapy. Serum testosterone was measured before treatment. The mean IIEF5 among all patients increased from 8.5 ± 3.9 to 20 ± 4.2 after sildenafil use (P < 0.0001). In patients younger than 70 years, the IIEF5 score increased from 9.5 ± 5.0 to 17 ± 4.3 while in patients 70 years and older, the score increased from 8.2 ± 3.6 to 21 ± 3.9, a near normalization. The rate of improvement in younger men was higher than in older men. Serum testosterone before treatment was similar in the two groups. The most commonly experienced adverse events were flushing and dyspepsia, which occurred in 6.8% and 2.3%, respectively. No patients discontinued sildenafil treatment due to adverse events. In conclusion, oral sildenafil is efficacious and well tolerated by elderly men with ED, even among those older than 70 years.     

Quality of life measures and outcome in alcohol-dependent men and women.

A sample of 82 (41 men 41 women) DSM IV alcohol-dependent inpatients admitted for detoxification was studied at baseline and followed-up 12 weeks thereafter. The following questionnaires were administered 4-5 days after admission for detoxification: Socio-demographic information, Severity of Alcohol Dependence Questionnaire (SADQ), Alcohol Problems Questionnaire (APQ), Rotterdam Symptoms Checklist (RSCL), Life Situation Survey (LSS), Beck Depression Inventory (BDI), General Health Questionnaire (GHQ 12), and Nottingham Health Profile (NHP). All indices other than socio-demographic data, the SADQ, and APQ were administered at 12-week follow-up. After controlling for confounding factors at baseline, women were more likely to be in a higher social class, prescribed anti-depressants during the previous 12 months, drink fewer units of alcohol in a typical week, and have a higher level of psychiatric caseness scores (GHQ-12). A total of 80 subjects (97%) were successfully followed-up. Difference between gender did not significantly impact upon any of the 12-week outcome measures. There was no significant difference in the study relapse rates or time taken to relapse between men and women. The only significant total sample change was a reduction in the amount of alcohol consumed in a typical week. This was significantly related to changes in the following Quality of Life (QoL) measures, NHP emotional reaction sub-scores, LSS, and BDI scores.     

Alcohol consumption, abstaining, health utility, and quality of life--a general population survey in Finland

AIMS: To examine the associations between alcohol consumption and utility-based health-related quality of life (HRQoL), subjective quality of life (QoL), self-rated health (SRH), and mental distress. METHODS: Representative general population survey in Finland, with 5871 persons aged 30-64 years. HRQoL was measured with two health utility instruments (15D and EQ-5D), QoL and SRH were measured with RATING scales, and mental distress with a General Health Questionnaire (GHQ-12). Past alcohol problems were diagnosed with a structured psychiatric interview known as the composite international diagnostic interview (CIDI). Alcohol consumption was examined with a self-report questionnaire. RESULTS: Negative associations between alcohol and well-being were observed on several measures for women consuming more than 173 g and men more than 229 g per week. Former drinkers scored worst on most measures, even in comparison to the highest drinking decile. For men, all statistically significant associations between moderate drinking and well-being disappeared when sociodemographic factors and former drinkers were controlled for. For women, moderate alcohol use associated with better SRH and EQ-5D as compared to abstainers. However, the possible health utility benefits associated with moderate alcohol consumption were of clinically insignificant magnitude. CONCLUSIONS: Failure to separate former drinkers and other abstainers produces a significant bias favoring moderate drinkers. As the possible health utility benefits of moderate alcohol use were clinically insignificant, it suffices to investigate mortality, when estimating the public health impact of moderate alcohol consumption using quality-adjusted life years.     

A novel therapy with testosterone and sildenafil for erectile dysfunction in patients on renal dialysis or after renal transplantation

BACKGROUND: We undertook a prospective pilot study in a small cohort of patients with renal replacement therapy to determine the cause of erectile dysfunction (ED) and evaluate the role of testosterone replacement therapy and sildenafil. METHODS: We investigated 12 patients (eight post-transplant and four on haemodialysis) who presented with ED for hypogonadism and cavernosal insufficiency. We assessed sexual performance before and after treatment by a questionnaire method based on the modified International Index of Erectile Function (IIEF) and National Institutes of Health (NIH) rating. Patients received 250 mg intramuscular monthly injections of testosterone cypionate and 50-100 mg sildenafil orally once or twice weekly for 12 months. Therapeutic response was considered good if the patient could maintain an erection adequate for successful sexual intercourse (NIH criteria) and had a marked improvement in the overall sexual performance (IIEF scoring). RESULTS: Before treatment all patients had severe ED with a poor IIEF score while 11 also had diminished libido. Eleven patients had diminished testicular volume and six had elevated follicle-stimulating hormone levels suggestive of germ cell damage. All patients had a good response to the therapeutic trial of testosterone and sildenafil. CONCLUSIONS: Therapy with testosterone and sildenafil may be indicated for those with both cavernosal arterial insufficiency and reproductive hormone abnormalities. Further longer-term data are needed to determine the safety and efficacy of this novel regimen.     

Erectile dysfunction: a significant health need in patients with coronary heart disease

BACKGROUND AND AIMS: Erectile dysfunction (ED) is a common condition, which negatively affects quality of life, and shares similar risk factors with Coronary Heart Disease (CHD). Studies from the pre - sildenafil era confirm a higher risk of ED in patients with cardiovascular disease. The high profile and success of sildenafil therapy has made it easier for some men to discuss erectile difficulties with healthcare professionals. Our aim therefore was to estimate the prevalence of ED in our cardiac rehabilitation patients . METHODS AND RESULTS: We surveyed 150 random male cardiac rehabilitation patients using the International Index of Erectile Function (IIEF) questionnaire. 61% of all respondents had erectile difficulties, rising to 75% in the over 55 age group. 48% of respondents indicated their wish to discuss erectile problems with the healthcare team. CONCLUSION: ED and CHD commonly co-exist. A large proportion of our respondents wished further discussion of erectile insufficiency. We recommend that cardiac rehabilitation programmes should adopt a proactive approach to detection and treatment of ED.     

The assessment of sexual functions in women with male partners complaining of erectile dysfunction: does treatment of male sexual dysfunction improve female partner's sexual functions?

The aims of this prospective study were to compare sexual functioning between women with male partners who have erectile dysfunction (ED) and women without partners with ED and also to investigate the effect of the treatment of male ED on female partner's sexual function. The study included 87 women and their male partners. We divided the women into two groups: 38 women with male partners complaining of ED (ED group) and 49 women with male partners who have no ED (control group). Of the men with ED, 30 were treated with penile prosthesis implantation (n = 17) or oral sildenafil citrate (n = 13). We evaluated all the men with the International Index of Erectile Function (IIEF; Rosen, Cappelleri, Smith, Lipsky, & Pena, 1999), physical examination, and color penile Doppler ultrasound. We evaluated female sexual function with the Female Sexual Function Index (FSFI; Rosen et al., 2000) to assess sexual desire, arousal, lubrication, orgasm, satisfaction, and pain. We compared female sexual function scores between the women of the male partners with and without ED and also compared before both groups and after the treatment of male partners in the ED group. Additionally, we compare the scores according to the type of treatment given to the male partners. Sexual arousal (p = 0.009), lubrication (p = 0.001), orgasm (p = 0.006), satisfaction (p = 0.000), pain (p = 0.039), and total score (p = 0.003) were highly significantly lower in the ED group than in the control group, although sexual desire did not differ between the two groups (p = 0.515). We investigated the effect of male ED on female sexual functions and found no statistically significant differences in the presence of organic type impotence, older age, and lower erection scores on the IIEF (p = 0.53, p = 0.15, and p = 0.1, respectively). After the treatment of male ED, we observed significant improvement in sexual arousal (p = 0.001), lubrication (p = 0.002), orgasm (p = 0.000), satisfaction (p = 0.000), and pain (p = 0.002) in the women. These findings suggest that female sexual function is affected by male erection status and may improve after the treatment of male sexual dysfunction.     

Measurement of quality of life in alcohol-dependent subjects by a cancer symptoms checklist.

There are few studies of Quality of Life measures (QoL) in alcohol-misusing patients. The present study addresses this deficiency. The sample consisted of 60 (39 men, 21 women) alcohol dependent subjects defined by DSM-IV criteria (American Psychiatric Association, 1994). At baseline (4-5 days after admission and detoxification) sociodemographic data were collected, and three questionnaires were administered: the Rotterdam Symptoms Checklist (RSCL), the Severity of Alcohol Dependence Questionnaire (SADQ), and Alcohol Problems Questionnaire (APQ). QoL scores for dependent alcoholics both for physical and psychological measures were significantly worse (higher) than those reported for a variety of cancer patients. Psychological symptom scores were higher than physical symptoms at baseline. Correlations of RSCL scores to both SADQ and APQ were greater for RSCL physical compared to psychological symptom scores. The subjects were followed up at 12 weeks when the RSCL was re-administered and relapse status ascertained. Fifty-eight (97%) subjects were successfully contacted at 12 weeks of whom 36 (62%) had relapsed. After a repeated measures ANOVA psychological and physical symptom subscores were statistically significantly improved as a result of not relapsing to heavy drinking. There was no significant change in scores in the relapse group when baseline and week 12 scores were compared. The RSCL measure is a useful QoL assessment tool in alcohol-dependent subjects.     

Psychogenic erectile dysfunction: comparative study of three therapeutic approaches

We administered the International Index of Erectile Function (IIEF; Rosen et al., 1997) questionnaire to 30 patients with psychogenic erectile dysfunction (ED) at baseline, immediately after treatment, and 3 months after treatment. We randomized patients into three groups: group I, who had weekly sessions of time-limited theme-based group psychotherapy for 6 months and 50 mg sildenafil citrate orally on demand; group II, who had an intake of 50 mg sildenafil citrate orally on demand for 6 months only; and group III, who had weekly sessions of time-limited theme-based group psychotherapy for 6 months. We analyzed data (15-item IIEF) for each group at three times during the study and compared by the data using analysis of variance (ANOVA), followed by the Bonferroni multiple comparison test. We used Cochran's Q-test for analysis between baseline and posttreatment stages of patients with remission of symptoms (EF equal to or higher than 26 points). Group III had a mean score higher than group II, with the difference being statistically significant (immediately after treatment, p = 0.033; at 3 months after treatment, p = 0.049; p < 0.05). All three therapeutic alternatives resulted in an improvement of erectile function domain score. However, significant differences from baseline were observed in groups I (p = 0.0009) and III (p = 0.0002) but not in group II (p = 0.135). The psychotherapy groups, I and III, had significantly higher scores compared with group II, in which patients were exclusively treated with sildenafil citrate. These findings suggest that time-limited theme-based group psychotherapy is an effective treatment for psychogenic ED.     

Drinking patterns, psychological distress and quality of life in a Norwegian general population-based sample

Background

The purpose of this study was to investigate possible relationships between drinking patterns, psychological distress and quality of life (QoL) in a general population-based sample in Norway.

Methods

A random sample of 4,000 Norwegian citizens, aged 18 to 79, was drawn from the National Register held by Statistics Norway.

Results

Males consumed significantly more alcohol and reported more drinking-related problems with more negative consequences, compared to females. Psychological distress increased, and all QoL domain scores decreased with increasing alcohol consumption within the group drinking alcohol at all. The excessive drinkers demonstrated the highest level of psychological distress and lowest QoL in the psychological, social relationships and environment domains. Non-drinkers reported to have poorest QoL in the physical health domain, whereas light and moderate drinkers demonstrated lowest psychological distress and best QoL. Psychological distress demonstrated substantial more importance for QoL than socio-demographic variables, alcohol consumption, alcohol dependency and negative consequences of alcohol use did.

Conclusion

The findings indicate the need for a focus on psychological distress and its negative impact upon all QoL domains. Attention should also be paid to excessive drinkers who have poor QoL (psychological, social relationships and environment domains) and a high level of psychological distress. In addition, non-drinkers reported poor physical health. Further research is needed concerning the relation between alcohol consumption, psychological distress and QoL both in general population studies and in more specific samples.     

Beyond alcohol and drug addiction. Does the negative trait of low distress tolerance have an association with overeating?

Low distress tolerance is an inability to withstand negative emotions. The connection between low distress tolerance and addiction to cigarettes, alcohol, and illegal drugs has been established. The purpose of the current study was to extend this work to overeating, which is an important symptom of food addiction. We investigated whether low distress tolerance was related to overeating as measured by the emotional and external eating scales of the Dutch Eating Behavior Questionnaire and the disinhibition scale of the Three-Factor Eating Questionnaire. Participants were 225 college students with a median age of 19; 32% were overweight or obese. Linear regression models adjusting for sex and BMI demonstrated significant inverse associations among distress tolerance and emotional eating (P = 0.001), external eating (P = 0.002), and disinhibition (P < 0.001). These initial results suggest the importance of additional research in the area of low distress tolerance, overeating, and food addiction.     

Impact of comorbid diabetes on quality of life and perception of angina pain in people with angina registered with general practitioners in the UK

AIMS: To investigate the impact of comorbid diabetes on general and angina-related quality of life (QoL) in people with angina. METHODS: We analysed data for a subset of patients with angina, from a randomised controlled trial conducted in UK primary care. SF36 scores and Seattle Angina Questionnaire scores were compared for people with and without diabetes. We adopted a robust statistical approach, using nonparametric quantile regression to adjust for the influence of potential confounders. RESULTS: Data were available for 904 cases of whom 181 (20%) had diabetes. Presence of comorbid diabetes was significantly associated with reduced generic QoL for all SF36 domains and Seattle Angina Questionnaire physical limitation scores (estimated regression coefficient -12.33), but not for the other angina-related scores. Greater frequency of perceived angina was strongly correlated with reduced QoL (P<0.001) and angina frequency was similar in people with and without diabetes (P=0.576). CONCLUSIONS: Our results confirm the cumulative impact of having multiple chronic diseases on QoL. Though limited by the data available, our finding of similar angina frequency in patients with and without diabetes contributes to the debate regarding the influence of autonomic neuropathy on perception of angina in people with diabetes.     

Psychiatric morbidity and alcohol use by pregnant women in a public obstetric service

OBJECTIVE: To investigate the relationship between alcohol consumption and emotional distress in pregnant women, and to verify whether women with problematic alcohol consumption (abuse or dependence) have more emotional distress than those with non-problematic alcohol consumption. METHODS: A cross-sectional observational study was carried out in a clinical sample from a public obstetric service in Ribeir?o Preto, Brazil. A non-probabilistic convenience sample of patients who were consecutively recruited comprised 450 pregnant women. Three questionnaires were applied: a sociodemographic profile, followed by the Psychiatric Morbidity Questionnaire (QMPA) and a standardized questionnaire for collecting data on alcohol-related problems (abuse or dependence) according to ICD-10 criteria. Univariate analysis (ANOVA) was used for comparison between groups using central distribution measures and 95% confidence intervals. RESULTS: There were found 172 (38.2%) problematic pregnant women with positive score (score >7) in the QMPA. A group of 41 (9.1%) pregnant women with problematic alcohol consumption was detected according to ICD-10 criteria, 27 (6.0%) of them diagnosed as alcohol abuse and 14 (3.1%) as alcohol dependence. Alcohol abuse or dependence syndrome was related to greater emotional distress, i.e. higher mean scoring in anxiety, depression and alcohol QMPA subscales. CONCLUSIONS: Given the prevalence of emotional distress and alcohol consumption during pregnancy and high risk of mother-child health problems, careful evaluations in this population should be conducted by health professionals.     

Cardiovascular risk among men seeking help for erectile dysfunction

PURPOSE: The introduction of sildenafil put the risk of cardiovascular disease (CVD) among men with erectile dysfunction (ED) on the agenda of physicians. The question arose, Is EDsentinel to CVD? We sought to answer this question in the present study. METHODS: A historical cohort study was set up using medical records of general practices all over the Netherlands. Incident cases of ED were selected before and after the introduction of sildenafil using a catchment population of 60,000 men aged 35 to 74 years. Two to three men without ED (controls) were, subsequently, matched to each case. Incidence of CVD was determined for cases and controls, respectively. RESULTS: Overall, incidence of ED doubled from 5.3 per 1000 men-years in the period before introduction of sildenafil to 10.1 after the introduction. The relative risk of incident CVD among men with ED compared to controls was 1.7 [95%-CI 0.9-3.3] before the introduction and 1.1 [95%-CI 0.6-1.8] afterwards. CONCLUSIONS: While ED could be seen as a marker for CVD before the introduction of sildenafil, it was clearly not afterwards.     

The ED-EQoL: The development of a new quality of life measure for patients with erectile dysfunction

PURPOSE: To identify the important issues which have an impact on the quality of life (QoL) of men suffering from erectile dysfunction (ED) and to generate a new ED-specific QoL questionnaire ready to undergo further psychometric testing. METHODS: QoL issues relating to ED were generated through in-depth qualitative interviews of 29 patients, literature review and consultation with other healthcare professionals. The issues were formulated into a questionnaire, which was piloted using 40 patients with ED and subsequently refined using well-established principles of questionnaire development. RESULTS: The qualitative interviews revealed numerous psychosocial problems associated with ED, which were operationalised into a 40-item questionnaire. Pilot testing allowed the questionnaire to be reduced to a manageable 15-item final questionnaire while maintaining face and content validity and the potential to discriminate between men with varying degrees of affected QoL. This questionnaire had a Cronbach's alpha of 0.94. CONCLUSIONS: A new ED-specific QoL measure has been developed using appropriate methodology. Qualitative techniques identified a range of psychosocial morbidity in men with ED, leading to a simple but robust instrument with face and content validity. This questionnaire, Erectile Dysfunction-Effect on quality of life (ED-EQoL), has now undergone psychometric testing for validity and reliability.     

Favorable effect of sildenafil on erectile dysfunction in patients after radiotherapy for prostate cancer; randomised, double-blind, placebo-controlled crossover study

OBJECTIVE: To determine the efficacy of sildenafil in patients with erectile dysfunction after external beam radiotherapy for prostate cancer. DESIGN: Randomised, double-blind, placebo-controlled, crossover study. METHOD: A total of 406 patients with erectile dysfunction reported in their medical records who had completed external beam radiotherapy at least 6 months prior to the study, were approached by letter. Sixty patients were included in a study which lasted 12 weeks. They received 50 mg of sildenafil citrate or placebo for two weeks; during week 2 the dose could be increased to 100 mg in the case of unsatisfactory erectile response. At week 6 patients crossed over to the alternative treatment. Data were collected using the validated 'International index of erectile function' (IIEF) questionnaire, and side-effects were recorded. Patients were given the possibility of continuing to a 6-week open-label phase. RESULTS: The mean age of those participating was 68 years. All patients completed the double-blind phase. For the majority f questions in the IIEF questionnaire, there was a significant increase in mean scores from baseline with sildenafil, but of the patients with sildenafil, versus 18% with placebo. Ninety percent of the patients required a dose adjustment to 100 mg sildenafil, and 100% of the patients in the placebo group increased the dose. Side-effects were mild or moderate. Patients who proceeded to the open-label phase reported the same results as in the double-blind phase. CONCLUSION: Sildenafil improved erectile function in about half of the patients with erectile dysfunction after external beam radiotherapy for prostate cancer, and it was well tolerated.     

Psychological and interpersonal correlates in men with erectile dysfunction and their partners: a pilot study of treatment outcome with sildenafil

The role of psychological and interpersonal factors in the treatment of erectile dysfunction (ED) with sildenafil or other oral therapies has not been sufficiently investigated. We conducted a pilot study of psychosocial predictors of pharmacotherapy treatment outcome and satisfaction in men with ED and their partners. Sixty-nine men with mild to moderate ED and their partners were enrolled in a multicenter, open-label, treatment trial with sildenafil. Treatment measures included a battery of validated self-report measures and questionnaires. Subjects also were interviewed according to a semistructured interview protocol. Partner assessments included self-report measures of sexual function, mood, and relationship satisfaction. Results indicated that, prior to treatment, patients had erectile function scores in the range of mild to moderate ED, with relatively low levels of concomitant depression, anxiety, and psychological stress and high overall levels of relationship adjustment. Partner sexual function was in the normal range of total Brief Index of Sexual Functioning for Women (BISF-W; Taylor, Rosen, Leiblum, 1994) scores, although more than one third of female partners had specific sexual complaints or problems. Among couples who completed one or both follow-up visits (N = 34), sildenafil treatment resulted in significant improvements in all aspects of sexual function in men, including sexual desire, orgasmic function, erectile function and overall sexual satisfaction. Significant improvements also were noted in partners' ratings of sexual function in most domains, including arousal, pleasure, and orgasm. Higher baseline levels of sex-specific anxiety were negatively associated with improvement in erections following treatment. Relationship adjustment at baseline, contrary to expectations, did not predict erectile or sexual satisfaction following treatment in the men or their partners but was significantly correlated with changes in sexual desire. Baseline levels of depression, anxiety, and stress generally were unrelated to efficacy or treatment satisfaction. However, we observed a curvilinear relationship in the men between baseline levels of stress and treatment discontinuation (i.e., subjects with moderate levels of stress were less likely to discontinue treatment). Because of a high number of dropouts, results of this pilot study await confirmation in a larger and more adequately powered clinical trial.     

A community-based study of enduring eating features in young women

We conducted a prospective exploration of the temporal course of eating disorder (ED) symptoms in two cohorts of community women. One hundred and twenty-two young women (Cohort 1) identified in a general population based survey with ED symptoms of clinical severity agreed to participate in a 5-year follow-up study. A comparative sample (Cohort 2) of 706 similar aged self-selected college women (221 with disordered eating) was recruited one year later. Both ED groups were given a health literacy package in the first year. ED symptoms, health related quality of life, and psychological distress were assessed annually with the Eating Disorder Examination Questionnaire, the Short Form-12 Health Survey and the Kessler Psychological Distress Scale, respectively. Forty percent (Cohort 1) and 30.3% (Cohort 2) completed questionnaires at each year of follow-up. In both groups, there was early improvement in ED symptoms which plateaued after the first year, and participants retained high EDE-Q scores at 5 years. BMI increased as expected. Mental health related quality of life scores did not change but there were small improvements in psychological distress scores. The findings suggest little likelihood of spontaneous remission of ED problems in community women.     

The Correlation Between the Comprehensive Nutrition Index and Quality of Life of Patients with Nasopharyngeal Carcinoma Treated by Intensity-Modulated Radiotherapy

The purpose of this study was to compare the changing tendency of nutrition with 54 nasopharyngeal carcinoma patients during intensity-modulated radiation therapy (IMRT), and to investigate the correlation between comprehensive nutritional status and quality of life (QoL), which was assessed by the European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire. The nutritional index, including body mass index, ideal body weight percentage, usual body weight percentage, albumin, hemoglobin, and total lymphocyte count (TLC), was evaluated at 2 time points: within 48 h after admission (T₁) and at the end of treatment with IMRT (T₂). A statistically significant downgrade of every index was observed during IMRT. A comprehensive nutritional model was established by principal components analysis at T₂. QoL scores of functional (P = 0.002) and the global QoL scales (P = 0.001) existed a positive correlation with comprehensive nutritional status. QoL scores of symptom scales (P = 0.002) and 6 single items (P = 0.005) had a negative correlation with it. The scores of global QoL scales in comprehensive nutrition of normal (20.4%), moderate (55.6%), and severe malnutrition (24.1%) were 69.70 ± 17.98, 48.33 ± 19.25, and 37.18 ± 24.67, respectively. Patients with different nutritional status had different QoL (B = 10.405, SE = 2.828, t = 3.680, P = 0.001). Multiaspect nutritional supports should be enhanced to improve patients’ comprehensive nutritional status during treatment.
