The effect of metoprolol on mortality was compared with that of placebo in a double blind randomised trial in patients with definite or suspected acute myocardial infarction. Treatment with metoprolol or placebo started as soon as possible after the patients arrival in hospital and was continued for 90 days. Metoprolol was given as a 15 mg intravenous dose followed by oral administration of 100 mg twice daily. 1395 patients (697 on placebo and 698 on metoprolol) were included in the trial. Definite acute myocardial infarction developed in 809 and probable infarction in 162. Patients were allocated to various risk groups and within each group patients were randomly assigned to treatment with metoprolol or placebo. There were 62 deaths in the placebo group (8.9%) and 40 deaths in the metoprolol group (5.7%), a reduction of 36% (p less than 0.03). Mortality rates are given according to the treatment group to which the patients were initially randomly allocated.

This study defines the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) quality of life (QOL) questionnaire designed to measure the QOL of patients with ovarian cancer. The ovarian cancer module (EORTC QLQ-OV28) was developed to supplement the EORTC QLQ-C30. The core questionnaire and the QLQ-OV28 were prospectively administered to 368 ovarian cancer patients after they had been treated with radical or debulking surgery followed by chemotherapy. The QLQ-OV28 module assesses abdominal/gastrointestinal symptoms, peripheral neuropathy, other chemotherapy side-effects, hormonal/menopausal symptoms, body image, attitude to disease/treatment and sexual functioning. Questionnaires were well accepted by patients, baseline compliance rates were 86%, 72% provided a second assessment, less than 3% of the items had missing data. Multi-trait scaling analyses confirmed the hypothesised scales. All hypothesised scales exhibited good psychometric properties. These results support the clinical and psychometric validity of the EORTC QLQ-OV28 module as a supplement to the EORTC QLQ-C30.

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 Cronbachs 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.

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.

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 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.

ABSTRACT 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.

Johan Herlitz; Å Hjalmarson; Stig Holmberg; Lars Rydén; Karl Swedberg; Finn Waagstein; Ann-Charlotte Waldenström

The variability of chest pain is described in 389 patients with acute myocardial infarction. Whereas 17% were free from severe pain after arrival in hospital, 11% required more than 10 analgesic injections. In 27% of the series analgesics were given more than 24 h after arrival in hospital. Predictors for the severity of chest pain were the rate-pressure product and degree of chest pain soon after arrival in hospital as well as electrocardiographic signs of myocardial infarction at entry. Patients with more severe chest pain had a higher 2-year mortality rate and a higher incidence of ventricular fibrillation and congestive heart failure during hospitalization.
