RESUMO
BACKGROUND: Quality of life (QoL) is a key outcome measure in healthcare. However, the heterogeneity in its definitions presents challenges in the objective evaluation of improvement. Universal questionnaires, tailored for a broad demographic group, inadequately represent the unique experiences of intensive care unit (ICU) survivors, including a lack of ability to discriminate issues related to QoL from issues that do not. METHODS: Using a 218-item, 13-domain provisional questionnaire, we assessed 395 adult ICU survivors, with a minimum 72-h stay at one of three Swedish university hospital ICUs, at 6 months to three years post-discharge. Their responses were compared to those of 195 controls, matched for age and sex and randomly recruited from the Swedish Population Registry. By multi-group exploratory factor analysis, we compared dimensionality in QoL perceptions between the two groups, emphasising patterns of correlation to 13 domain-specific QoL questions. Model fit was assessed using information criteria. Internal consistency reliability for each scale was determined using McDonald's omega or Cronbach's alpha. All analyses were conducted using Mplus, applying full information maximum likelihood to handle missing data. RESULTS: All domains except Cognition had a subset of questions correlating to the domain-specific QoL question in at least the ICU survivor group. The similarity between the two groups varied, with Physical health, Sexual health and Gastrointestinal (GI) functions mainly correlating the same issues to QoL in the two groups. In contrast, Fatigue, Pain, Mental health, activities of daily living, Sleep, Sensory functions and Work life showed considerable differences. In all, about one-fourth of the issues correlated to QoL in the ICU survivor group and about one-tenth of the issues in the control group. CONCLUSIONS: We found most issues experienced by ICU survivors to be unrelated to quality of life. Our findings indicate that the consequences of post-ICU issues may play a more significant role in affecting QoL than the issues themselves; issues restricting and affecting social life and work life were more related to QoL in ICU survivors than in non-ICU-treated controls. Caution is advised before associating all post-ICU problems with an effect on quality of life. TRIAL REGISTRATION: ClinicalTrials.gov Ref# NCT02767180; Registered 28 April 2016.

BACKGROUND: ICU survivors have lower quality of life (QoL) compared to a non-ICU-treated population. The reason for this is not fully understood, but differences in baseline characteristics may be an important factor. This study evaluates the roles of comorbidity and educational level as possible explanatory factors for differences in QoL in ICU survivors compared to a non-ICU-treated population. METHODS: Using a provisional questionnaire with 218 questions in 13 domains on QoL after intensive care, we compared the responses from 395 adult ICU survivors and 195 non-ICU-treated controls. An initial bivariable linear correlation analysis compared the responses from the two groups. Two secondary multivariable regression analyses tested for effect modification by comorbidity and educational level, respectively, on the effect on QoL from belonging to the ICU survivor group compared to the control group. RESULTS: There was a significant difference in QoL between the two groups in 170 of 218 (78%) questions. In the multivariable analyses, associations between group belonging and QoL remained in 139 questions. In 59 of these, both belonging to the ICU survivor group and comorbidity was associated to QoL, in parallel to each other. Comorbidity moderated the association between group belonging and QoL in six questions, with the highest proportion of questions within the domains of cognition and urinary functions, and the lowest proportion within appetite and alcohol, physical health, and fatigue. In 26 questions, both belonging to the ICU survivor group and educational level were associated to QoL, in parallel to each other. Educational level moderated the association between group belonging and QoL in 34 questions, with the highest proportion of questions within the domains of urinary functions, ADL and physical health, and the lowest proportion within the domains of cognition, appetite and alcohol, pain, sensory functions, and fatigue. CONCLUSIONS: Lower QoL seen in ICU survivors compared to non-ICU-treated controls, as measured by our provisional questionnaire, cannot be explained only by a higher burden of comorbidity, and rarely by only educational level. In issues where comorbidity or educational level was associated to QoL, it often was so in parallel to an association from belonging to the ICU survivor group. Comparing QoL in ICU survivors to that of a non-ICU-treated population may be adequate despite differences in baseline characteristics.

BACKGROUND: ICU survivorship includes a diverse burden of disease. Current questionnaires used for collecting information about health-related problems and their relation to quality of life lack detailed questions in several areas relevant to ICU survivors. Our aim was to construct a provisional questionnaire on health-related issues based on interviews with ICU survivors and to test if this questionnaire was able to show differences between ICU survivors and a control group. METHODS: Thirty-two ICU survivors were identified at a post-ICU clinic and interviewed at least six months after ICU discharge. Using an established qualitative methodology from oncology, all dysfunctions and disabilities were extracted, rephrased as questions and compiled into a provisional questionnaire. In a second part, this questionnaire was tested on ICU survivors and controls. Inclusion criteria for the ICU survivors were ICU stay at least 72 h with ICU discharge six months to three years prior to the study. A non-ICU-treated control group was obtained from the Swedish Population Register, matched for age and sex. Eligible participants received an invitation letter and were contacted by phone. If willing to participate, they were sent the questionnaire. Descriptive statistics were applied. RESULTS: Analysis of the interviews yielded 238 questions in 13 domains: cognition, fatigue, physical health, pain, psychological health, activities of daily living, sleep, appetite and alcohol, sexual health, sensory functions, gastrointestinal functions, urinary functions and work life. In the second part, 395 of 518 ICU survivors and 197 of 231 controls returned a completed questionnaire, the response rates being 76.2% and 85.3%, respectively. The two groups differed significantly in 13 of 22 comorbidities. ICU survivors differed in a majority of questions (p ≤ 0.05) distributed over all 13 domains compared with controls. CONCLUSIONS: This study describes the development of a provisional questionnaire to identify health-related quality of life issues and long-term burden of disease after intensive care. The questionnaire was answered by 395 ICU survivors. The questionnaire could identify that they experience severe difficulties in a wide range of domains compared with a control group.

BACKGROUND: To analyze the relationship between mean radiation dose to the bowels and the anal-sphincter and occurrence of 'defecation into clothing without forewarning', a specific and serious fecal incontinence symptom after gynecological radiotherapy. Additional potential risk factors associated with the symptom are explored. MATERIAL AND METHODS: Data were collected for 519 eligible gynecological cancer survivors, treated with pelvic radiotherapy, with a median follow-up of 5.8 years, using a study-specific questionnaire and medical records. Correlations between defecation into clothing without forewarning and mean dose to organs at risk; the anal-sphincter region, the rectum, the sigmoid and the small intestines were investigated, also taking other risk factors into account. RESULTS: Twelve percent reported having had the symptom at least once in the preceding six months. Mean doses >50 Gy to the anal-sphincter region, the rectum, the sigmoid and the small intestines were related to the occurrence of the symptom. Significantly associated risk factors were deliveries with high birth weight, heart failure and lactose and/or gluten intolerance. After adjusting for these factors, mean doses >50 Gy to the anal-sphincter region, the sigmoid and the small intestines remained related to the occurrence of the symptom. CONCLUSION: Mean doses to the bowels and anal-sphincter region are related to the risk of defecation into clothing without forewarning in long-term gynecological cancer survivors treated with pelvic radiotherapy. Further radiobiological modeling may distinguish which organ(s) contribute most to development of the symptom.

PURPOSE: The purpose of this study was to examine whether or not vaginal elasticity or lack of lubrication is associated with deep or superficial dyspareunia. We investigated gynecological cancer survivors treated with radiation therapy. METHODS: In a population-based study with 616 women answering a questionnaire (participation rate 78%) and who were treated with radiotherapy for gynecological cancer, we analyzed information from 243 women (39%) who reported that they had had intercourse during the previous six months. Analyses included log-binomial regression (relative risks) and multiple imputations by chained equations in combination with Bayesian Model Averaging, yielding a posterior probability value. Age range of this cancer recurrent-free group of women was 29-80. RESULTS: Dyspareunia affected 164 of 243 of the women (67%). One hundred thirty-four women (55%) reported superficial pain, 97 women (40%) reported deep pain, and 87 women (36%) reported both types of dyspareunia. The relative risk (RR) of deep dyspareunia was 1.87 (CI 1.41-2.49) with impaired vaginal elasticity compared to normal vaginal elasticity. Age and lower abdominal swelling were separate risk factors for deep dyspareunia. However, effects remain after adjusting for these factors. CONCLUSION: The relative risk of deep dyspareunia was almost twice as high with impaired vaginal elasticity compared to normal vaginal elasticity. If we wish to treat or even prevent deep dyspareunia in women with gynecological cancer, we may use our knowledge of the pathophysiology of deep dyspareunia and increasingly provide dilators together with instructions on how to use them for stretching exercises in order to retain vaginal elasticity. Results highlight the need for studies with more precise questions distinguishing superficial from deep dyspareunia so that in the future we may be able to primarily try to avoid reduced vaginal elasticity and secondarily reduce the symptoms.

BACKGROUND: Gastrointestinal (GI) morbidity after radiotherapy (RT) for prostate cancer is typically addressed by studying specific single symptoms. The aim of this study was to explore the interplay between domains of patient- reported outcomes (PROs) on GI morbidity, and to what extent these are explained by RT dose to the GI tract. MATERIAL AND METHODS: The study included men from two Scandinavian studies (N = 211/277) who had undergone primary external beam radiotherapy (EBRT) for localized prostate cancer to 70-78 Gy (2 Gy/fraction). Factor analysis was applied to previously identified PRO-based symptom domains from two study-specific questionnaires. Number of questions: 43; median time to follow-up: 3.6-6.4 years) and dose-response outcome variables were defined from these domains. Dose/volume parameters of the anal sphincter (AS) or the rectum were tested as predictors for each outcome variable using logistic regression with 10-fold cross-validation. Performance was assessed using area under the receiver operating characteristic curve (Az) and model frequency. RESULTS: Outcome variables from Defecation urgency (number of symptoms: 2-3), Fecal leakage (4-6), Mucous (4), and Pain (3-6) were defined. In both cohorts, intermediate rectal doses predicted Defecation urgency (mean Az: 0.53-0.54; Frequency: 70-75%), and near minimum and low AS doses predicted Fecal leakage (mean Az: 0.63-0.67; Frequency: 83-99%). In one cohort, high AS doses predicted Mucous (mean Az: 0.54; Frequency: 96%), whereas in the other, low AS doses and intermediate rectal doses predicted Pain (mean Az: 0.69; Frequency: 28-82%). CONCLUSION: We have demonstrated that Defecation urgency, Fecal leakage, Mucous, and Pain following primary EBRT for localized prostate cancer primarily are predicted by intermediate rectal doses, low AS doses, high AS doses, or a combination of low AS and intermediate rectal doses, respectively. This suggests that there is a domain-specific dose-response for the GI tract. To reduce risk of GI morbidity, dose distributions of both the AS region and the rectum should, therefore, be considered when prescribing prostate cancer RT.

PURPOSE: The aim of this study was to investigate what bowel organ and delivered dose levels are most relevant for the development of 'emptying of all stools into clothing without forewarning' so that the related dose-responses could be derived as an aid in avoiding this distressing symptom in the future. MATERIAL AND METHODS: Of the 77 gynecological cancer survivors treated with radiotherapy (RT) for gynecological cancer, 13 developed the symptom. The survivors were treated between 1991 and 2003. The anal-sphincter region, the rectum, the sigmoid and the small intestines were all delineated and the dose-volume histograms were exported for each patient. The dose-volume parameters were estimated fitting the data to the Relative Seriality (RS), the Lyman and the generalized Equivalent Uniform Dose (gEUD) model. RESULTS: The dose-response parameters for all three models and four organs at risk (OARs) were estimated. The data from the sigmoid fits the studied models best: D50 was 58.8 and 59.5 Gy (RS, Lyman), γ50 was 1.60 and 1.57 (RS, Lyman), s was 0.32, n was 0.13 and a was 7.7 (RS, Lyman, gEUD). The estimated volume parameters indicate that the investigated OARs behave serially for this endpoint. Our results for the three models studied indicate that they have the same predictive power (similar LL values) for the symptom as a function of the dose for all investigated OARs. CONCLUSIONS: In our study, the anal-sphincter region and sigmoid fit our data best, but all OARs were found to have steep dose-responses for 'emptying of all stools into clothing without forewarning' and thus, the outcome can be predicted with an NTCP model. In addition, the dose to the four studied OARs may be considered when minimizing the risk of the symptom.

PURPOSE: Lower limb lymphedema (LLL) is a common condition after pelvic cancer treatment but few studies have evaluated its effect on the quality of life and its consequences on daily life activities among gynecological cancer survivors. METHODS: We identified a cohort of 789 eligible women, treated with pelvic radiotherapy alone or as part of combined treatment of gynecological cancer, from 1991 to 2003 at two departments of gynecological oncology in Sweden. As a preparatory study, we conducted in-depth interviews with gynecological cancer survivors and constructed a study-specific questionnaire which we validated face-to-face. The questionnaire covered physical symptoms originating in the pelvis, demographic, psychological, and quality of life factors. In relation to the lymph system, 19 questions were asked. RESULTS: Six hundred sixteen (78 %) gynecological cancer survivors answered the questionnaire and participated in the study. Thirty-six percent (218/606) of the cancer survivors reported LLL. Overall quality of life was significantly lower among cancer survivors with LLL. They were also less satisfied with their sleep, more worried about recurrence of cancer, and more likely to interpret symptoms from the body as recurrence. Cancer survivors reported that LLL kept them from physical activity (45 %) and house work (29 %) and affected their ability to partake in social activities (27 %) or to meet friends (20 %). CONCLUSION: Lower limb lymphedema has a negative impact on quality of life among gynecological cancer survivors, affecting sleep and daily life activities, yet only a few seek professional help.

Every year medical researchers make contact with a large number of cancer survivors with the aim of evaluating cancer treatment. For this reason we decided to investigate how Swedish cancer survivors perceived their participation in research studies focusing on the long-term consequences of being a survivor of gynaecological or urinary bladder cancer. Data were collected by means of two study-specific postal questionnaires, both consisting of questions covering physical symptoms, well-being and the experience of being a cancer survivor. Both questionnaires also included questions evaluating the participants' experience of being research subjects. The questionnaires were developed in close co-operation with cancer survivors. The study population consisted of 1068 cancer survivors. Of these, 95% (n=1003) reported that they thought the study was valuable and 54% (n=559) that they had been positively affected by participating. Four per cent (n=39) expressed that they had been negatively affected by their participation in the study. The vast majority of the cancer survivors thought that participating in their particular study was valuable.

BACKGROUND: Many patients treated with radiotherapy to the pelvic region report a change in bowel habits. Loose stools, urgency and fecal incontinence may have a significant impact on daily life and social functioning. MATERIAL AND METHODS: We attempted to follow up 789 women, treated with pelvic radiotherapy for a gynecological cancer during 1991 to 2003 at two departments of gynecological oncology in Sweden. A control group of 478 women from the Swedish Population Registry was also included. As a preparatory study, we made in-depth interviews with 26 women previously treated for gynecological cancer. Based on their narratives, we constructed a study-specific questionnaire including 351 questions and validated it face-to-face. The questionnaire covered questions of physical symptoms originating in the pelvis, demographics, psychological and quality of life factors. In relation to bowel symptoms, 60 questions were asked. RESULTS: Six-hundred and sixteen (78%) gynecological cancer survivors and 344 (72%) control women participated. Two-hundred and twenty-six (37%) cancer survivors reported loose stools at least once a week. Eighty-three percent of the survivors with loose stools every day reported defecation urgency with fecal leakage, compared to 20% of cancer survivors without loose stools. Cancer survivors with loose stools at least once a week were 7.7 times more likely to suffer from defecation urgency with fecal leakage (95% CI 4.4-13.3) compared to those who had loose stools once a month or less. In order to avoid loose stools affected survivors with loose stools often skipped meals (13%), made an active choice of food (47%) and preferentially used prescribed medication (36%). DISCUSSION: There is a relation between loose stools and defecation urgency with fecal leakage among long-term gynecological cancer survivors treated with pelvic radiotherapy. Targeting loose stools can possibly help survivors to decrease frequency of fecal leakage.

UNLABELLED: In preparation for studies of dose volume of ionizing radiation and long-term side effects, we assessed both variation in position and volume of organs at risk in the small pelvis. MATERIAL AND METHODS: On 10 men and seven women we delineated the sigmoid, rectum, anal sphincter, bladder, penile bulb, and cavernous bodies in two CT scans taken between five to 69 days apart. RESULTS: The measured overlap of the two delineated volumes divided by the maximum possible overlap, was below 50% for the sigmoid in six of 17 patients, for the distal 4 cm of the sigmoid in five of 17 patients, for the rectum in none of 17 patients, for the anal sphincter in three of 17 patients and for the urinary bladder in none of 17 patients. The smaller volume divided by the larger volume was below 50% in three of 17 patients for the sigmoid, in six of 17 patients for the 4 distal cm of the sigmoid, in two of 17 patients for the rectum, in two of 17 patients for the anal sphincter and in seven of 17 patients for the urinary bladder. For the urinary bladder the largest deviation was found cranially, 4.0 cm (SD 2.0 cm), the caudal part being relatively fixed. For the rectum the largest deviation was found in the anterior wall, 1.8 cm (SD 0.7 cm), with maximum documented variation in cranial direction of 3.2 cm (SD 1.8 cm). CONCLUSIONS: The sigmoid varies considerably in documented position with the largest deviation anteriorly, the urinary bladder change in volume with the extension mainly located cranially and for the rectum the anterior wall is the most mobile with the distension becoming more pronounced cranially. In modeling dose-volume effects one may consider our results.

INTRODUCTION: Fecal incontinence is a symptom reported by cancer survivors after pelvic radiotherapy and is recognized to be one of the most troubling symptom-induced sources of distress to patients. OBJECTIVE: To investigate how fecal incontinence, patient-reported as emptying of all stools into clothing without forewarning, impact self-assessed quality of life from a social, psychological, sexual, and functional aspect among gynecological cancer survivors treated with pelvic radiotherapy. METHODS: We identified a cohort of 789 eligible women in the Stockholm and Gothenburg areas treated with pelvic radiotherapy alone or as combined treatment of gynecological cancer. From the Swedish Population Registry, we identified 478 control women. Data were collected using a study-specific, validated, postal questionnaire including questions covering symptoms from the pelvic region, demographics, social functioning, psychological, and quality-of-life issues. RESULTS: Participation was 78% for cancer survivors and 72% for control women. The fecal incontinence symptom emptying of all stools into clothing without forewarning was reported by 70 cancer survivors (12%), with lowered quality of life in 74% of the 70 cancer survivors. This symptom kept the survivors from going to parties (relative risk [RR], 11.8; 95% confidence interval [CI], 6.6-21.1), kept the survivors from traveling (RR, 9.3; 95% CI, 5.3-16.5), affected their work ability (RR, 7.9; 95% CI, 3.8-16.4), hindered their sexual life (RR, 9.2; 95% CI, 4.8-17.6), and changed them as persons (RR, 4.9; 95% CI, 2.9-8.1). The prevalence of the symptom emptying of all stools into clothing without forewarning among control women was 3 (1%) of 344. CONCLUSIONS: Among gynecological cancer survivors having undergone pelvic radiotherapy alone or as part of a combined treatment, fecal incontinence is associated with social, psychological, sexual, and functional consequences.

BACKGROUND AND PURPOSE: In uterine cervical cancer tumour spread reaching the para-aortic lymph nodes is the most significant independent pre-treatment predictor of progression-free survival. When introducing [18F]fluorodeoxyglucose-positron emission tomography (FDG-PET)/computed tomography (CT) in our clinic for patients with advanced cervical cancer planned for definitive radiochemotherapy, the purpose of this study was to quantify to what extent the added information lead to changes in radiotherapy planning. MATERIAL AND METHODS: We included 25 consecutive patients with cervical cancer stages IB2 - IIIB planned for definitive radiochemotherapy between November 2010 and May 2012. The patients were examined both with magnetic resonance imaging (MRI) and FDG-PET/CT before treatment and after four weeks of treatment. RESULTS: In 11/24 (46%) of the patients the FDG-PET/CT before treatment provided additional diagnostic information leading to changes in treatment planning compared to information from MRI. Seven of these eleven patients (64%) were alive and without evidence of disease at four-year follow-up. The MRI detected pelvic tumour spread not seen on the FDG-PET/CT in 2/24 patients. The disease-free four-year survival was 59%. CONCLUSIONS: Additional diagnostic information from FDG-PET/CT changed treatment strategy in almost half of the patients and may have increased chances of survival in this limited group of patients with locally advanced uterine cervical cancer. We recommend both modalities for nodal detection.
RESUMO
BACKGROUND AND PURPOSE: To investigate the dose-response relation between the dose to the vagina and the patient-reported symptom 'absence of vaginal elasticity' and how time to follow-up influences this relation. MATERIAL AND METHODS: The study included 78 long-term gynecological cancer survivors treated between 1991 and 2003 with external beam radiation therapy. Of those, 24 experienced absence of vaginal elasticity. A normal tissue complication model is introduced that takes into account the influence of time to follow-up on the dose-response relation and the patient's age. The best estimates of the dose-response parameters were calculated using Probit, Probit-Relative Seriality (RS) and Probit-time models. Log likelihood (LL) values and the Akaike Information Criterion (AIC) were used to evaluate the model fit. RESULTS: The dose-response parameters for 'absence of vaginal elasticity' according to the Probit and Probit-time models with the 68% Confidence Intervals (CI) were: LL=-39.8, D50=49.7 (47.2-52.4) Gy, γ50=1.40 (1.12-1.70) and LL=-37.4, D50=46.9 (43.5-50.9) Gy, γ50=1.81 (1.17-2.51) respectively. CONCLUSIONS: The proposed model, which describes the influence of time to follow-up on the dose-response relation, fits our data best. Our data indicate that the steepness of the dose-response curve of the dose to the vagina and the symptom 'absence of vaginal elasticity' increases with time to follow-up, while D50 decreases.

AIM: Annually about 500,000 women worldwide are diagnosed with cervical cancer. For many patients, young age at the time of diagnosis and a good prognosis regarding the disease imply a long life with the side-effects and sequels of various treatment options. The present study investigated the extent to which different quality of life (QoL) domains in patients during and after treatment for cervical cancer are affected according to menopausal status, treatment status and treatment modality. METHODS: QoL data from 346 cervical cancer patients from 14 countries who were included in a cervical cancer module validation study of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of life Group were analysed according to menopausal status, treatment status and treatment modality. QOL was assessed using the EORTC Quality of life Questionnaire (QLQ)-C30 and the QLQ-CX24 module. Statistical analyses were performed using descriptive statistics and analysis of covariance. RESULTS: Active treatment had the strongest negative impact on 13 different QoL domains: physical, role, emotional, cognitive, social functioning, global health/QoL, fatigue, nausea and emesis, pain, appetite loss, constipation, symptom experience and sexual enjoyment. Irradiation alone ± other therapy was associated with most symptoms of diarrhoea. Age had the most negative impact on sexual activity and the strongest positive effect on sexual worry. CONCLUSION: Our results revealed that patients with cervical carcinoma had different side-effects with different impacts on QOL depending on the menopausal status and therapy modalities. Patients should be informed about the possibility that therapy may have a negative impact on QoL.

PURPOSE: To investigate the relative importance of patient-reported hip and sacral pain after pelvic radiotherapy (RT) for gynecological cancer and its relationship to the absorbed doses in these organs. METHODS AND MATERIALS: We used data from a population-based study that included 650 long-term gynecological cancer survivors treated with pelvic RT in the Gothenburg and Stockholm areas in Sweden with a median follow-up of 6 years (range, 2-15) and 344 population controls. Symptoms were assessed through a study-specific postal questionnaire. We also analyzed the hip and sacral dose-volume histogram data for 358 of the survivors. RESULTS: Of the survivors, one in three reported having or having had hip pain after completing RT. Daily pain when walking was four times as common among the survivors compared to controls. Symptoms increased in frequency with a mean absorbed dose >37.5 Gy. Also, two in five survivors reported pain in the sacrum. Sacral pain also affected their walking ability and tended to increase with a mean absorbed dose >42.5 Gy. CONCLUSIONS: Long-term survivors of gynecological cancer treated with pelvic RT experience hip and sacral pain when walking. The mean absorbed dose was significantly related to hip pain and was borderline significantly related to sacral pain. Keeping the total mean absorbed hip dose below 37.5 Gy during treatment might lower the occurrence of long-lasting pain. In relation to the controls, the survivors had a lower occurrence of pain and pain-related symptoms from the hips and sacrum compared with what has previously been reported for the pubic bone.

PURPOSE: To analyze the relationship between mean absorbed dose to the pubic bone after pelvic radiotherapy for gynecological cancer and occurrence of pubic bone pain among long-term survivors. METHODS AND MATERIALS: In an unselected, population-based study, we identified 823 long-term gynecological cancer survivors treated with pelvic radiotherapy during 1991-2003. For comparison, we used a non-radiation-treated control population of 478 matched women from the Swedish Population Register. Pain, intensity of pain, and functional impairment due to pain in the pubic bone were assessed with a study-specific postal questionnaire. RESULTS: We analyzed data from 650 survivors (participation rate 79%) with median follow-up of 6.3 years (range, 2.3-15.0 years) along with 344 control women (participation rate, 72 %). Ten percent of the survivors were treated with radiotherapy; ninety percent with surgery plus radiotherapy. Brachytherapy was added in 81%. Complete treatment records were recovered for 538/650 survivors, with dose distribution data including dose-volume histograms over the pubic bone. Pubic bone pain was reported by 73 survivors (11%); 59/517 (11%) had been exposed to mean absorbed external beam doses <52.5 Gy to the pubic bone and 5/12 (42%) to mean absorbed external beam doses ≥ 52.5 Gy. Thirty-three survivors reported pain affecting sleep, a 13-fold increased prevalence compared with control women. Forty-nine survivors reported functional impairment measured as pain walking indoors, a 10-fold increased prevalence. CONCLUSIONS: Mean absorbed external beam dose above 52.5 Gy to the pubic bone increases the occurrence of pain in the pubic bone and may affect daily life of long-term survivors treated with radiotherapy for gynecological cancer.

AIM: A validation study was conducted to evaluate the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Endometrial Cancer Module (EORTC QLQ-EN24). This module was designed to assess disease and treatment specific aspects of the quality of life (QoL) of patients with endometrial cancer. METHODS: Two hundred and sixty-eight women with endometrial cancer were recruited in different phases of treatment: after pelvic surgery (Group 1); during adjuvant chemotherapy and/or radiotherapy (Group 2); after completion of treatment (Group 3). Patients completed the EORTC QLQ-C30, the endometrial cancer module and a short debriefing questionnaire. RESULTS: Multi-trait scaling analyses confirmed the hypothesised scale structure of the QLQ-EN24. Internal consistency reliability was good with Cronbach's alpha coefficients ranging from 0.74 to 0.86 (lymphoedema 0.80, urological symptoms 0.75, gastrointestinal symptoms 0.74, body image problems 0.86 and sexual/vaginal problems 0.86). Convergent and discriminant validity did not show any scaling errors for the subscales. The QLQ-EN24 module discriminated well between clinically different groups of patients. All items exhibited a high completion rate with less than 2% missing values except for the sexuality items (19%). CONCLUSION: The validation study supports the reliability, the convergent and divergent validity of the EORTC QLQ-EN24. This newly developed QLQ-EN24 module is a useful instrument for the assessment of the QoL in patients treated for endometrial cancer in clinical trials.

AIM OF THE STUDY: To make a comprehensive, detailed inventory of gastrointestinal symptoms reported by gynaecological cancer survivors and control women from the general population. METHOD: We identified a cohort of 789 eligible women in the Stockholm and Gothenburg areas, treated with pelvic radiotherapy during the period 1991-2003, alone or as combined treatment, for gynaecological cancer. As controls, we randomly recruited 478 women, frequency matched by age and residence from the Swedish Population Registry. We collected data in 2006 by means of a study-specific, validated, postal questionnaire including 351 questions covering symptoms from the pelvic region. We asked about demographics, psychological and quality-of-life issues as well as social functioning. RESULTS: Participation was 78% for cancer survivors and 72% for controls. Mean follow-up was 7.2 years. In this large, population-based study, the greatest age-adjusted absolute risk difference between cancer survivors and control women was observed for the symptom defaecation urgency with faecal leakage and the highest age-adjusted relative risk for emptying of all stools into clothing without forewarning. CONCLUSIONS: Cancer survivors having undergone pelvic radiotherapy alone or as part of combined treatment between the period 1991-2003 for a gynaecological malignancy had a higher occurrence of long-lasting gastrointestinal symptoms as compared to population controls.

BACKGROUND: The authors report on the development and validation of a cervical cancer module for the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life (QoL) questionnaire (QLQ), which was designed to assess disease-specific and treatment-specific aspects of QoL in patients with cervical cancer. METHODS: The cervical cancer module (EORTC QLQ-CX24) was developed in a multicultural, multidisciplinary setting to supplement the EORTC QLQ-C30 core questionnaire. The QLQ-C30 and the cervical cancer module were administered to 346 patients with cervical cancer who underwent radical hysterectomy and received radiotherapy and chemotherapy. Psychometric analyses were performed by using data from 2 independent samples. RESULTS: The QLQ-CX24 consists of 3 multiitem scales and 5 single-item scales. Multitrait scaling analyses revealed high internal consistencies for the subscales with Cronbach alpha coefficients ranging from .72 to .87 (Symptom Experience, .72; Body Image, .86; Sexual/Vaginal Functioning, .87). Convergent and discriminant validity were fulfilled with scaling errors below 3%. The QLQ-CX24 was capable of discriminating between clinical subgroups. All items exhibited good compliance with <3% missing values. Most patients completed the EORTC QLQ-C30 and the QLQ-CX24 in <15 minutes (86%), and many did not require any assistance to complete the questionnaires (65%). CONCLUSIONS: The current psychometric analyses supported the content and construct validity and the reliability of the EORTC QLQ-CX24 module. This newly developed module is a useful instrument for assessing the QoL of patients who are treated for cervical cancer both in clinical trials and in clinical practice.
