- Objective: The influence of specific symptoms on emotions and social activities in the individual patient vanes. Little is known about this variation in urinary bladder cancer survivors (in other words, about the relative importance of sources of symptom-induced distress). Methods: We attempted to enrol 404 surgical patients treated with cystectomy and a conduit or reservoir in four Swedish towns (Stockholm, Orebro, Jonkoping, Linkoping), 101 surgical patients treated with cystectomy and orthotopic neobladder at the Herlev Hospital in Copenhagen, Denmark, and 71 patients treated with radical radiotherapy for bladder cancer, as well as 581 men and women controls in Stockholm and Copenhagen. An anonymous postal questionnaire was used to collect the information. Results: A total of 503 out of 576 (87%) treated patients and 422 out of 581 (73%) controls participated but 59 patients were excluded. The primary source of self-assessed distress among cystectomised patients was compromised sexual function, reduced intercourse frequency caused great distress in 19% of the conduit patients, 20% of the reservoir patients and 19% of the bladder substitute patients. The primary source of self-assessed distress in patients treated with radical radiotherapy was symptoms from the bowel, 17% reported great distress due to diarrhoea, 16% due to abdominal pain, 14% due to defecation urgency and 14% due to faecal leakage. The highest proportion of subjects being distressed was 93% (substantial: 43%, moderate: 29% and little: 21%) for treated upper or lower urinary retention (indwelling catheter or nephrostomy). Conclusion: The distress caused by a specific symptom varies considerably and the prevalence of symptoms causing great distress differs between treatments in bladder cancer survivors. It is possible that patient care and clinical research can be made more effective by focusing on important sources of symptom-induced distress. (C) 2003 Elsevier Science B.V. All rights reserved.

- OBJECTIVE: To evaluate how an increasing burden of symptoms influences well-being, anxiety and depression at different intervals after a radical cystectomy with urostomy for bladder cancer, as this therapy can induce long-term distressful symptoms. PATIENTS AND METHODS: Patients with bladder cancer undergoing radical cystectomy in Stockholm between 1969 and 1995 were matched with 434 controls from the normal population, all 404 patients operated on between 1985 and 1995 at three other hospitals in Sweden were invited to enter the study. The final analysis included 306 patients and 310 controls, all assessed for symptoms and well-being. RESULTS: A low or moderate level of well-being was reported by 35% of the patients having none or one of the symptoms studied, by 39% with two symptoms, by 45% with three symptoms and by 66% of those with four or more symptoms. The values, irrespective of symptom burden, were 45% after 2-5 years of follow-up, 58% after 6-10 years and 38% at > 10 years after surgery. The total symptom burden also influenced the risk of anxiety and depression. Symptom prevalence remained largely unaffected by the duration of follow-up, except for defecation urgency. CONCLUSIONS: The number of long-term symptoms after radical surgery with a urostomy for urinary bladder cancer affects the risk of anxiety, depression and low or moderate well-being.

- Introduction & Objectives: Although surveillance after radical prostatectomy routinely includes repeated Prostate Specific Antigen (PSA)-testing for many years, biochemical recurrence often occurs without further clinical progression. We therefore hypothesised that follow-up can be shortened for many patients without increasing the risk for prostate cancer death. We investigated the long-term probabilities of PSA recurrence, metastases and prostate cancer death in patients without biochemical recurrence 5 and 10 years after radical prostatectomy.Materials & Methods: Between 1989 and 1998, 14 urological centres in Scandinavia randomized patients to the Scandinavian Prostate Cancer Group study number 4 (SPCG-4) trial. Data was collected prospectively. All 306 patients from the SPCG-4 trial who underwent radical prostatectomy within 1 year from inclusion were eligible in our cohort. 4 patients were excluded due to surgery-related death (n=1) or salvage radiotherapy or hormonal treatment within 6 weeks from surgery (n=3). We stratified by Gleason score (≤3+4=7 or ≥4+3=7), pathological tumour stage (pT2 or ≥pT3), and negative or positive surgical margins. We analysed the cumulative incidences and absolute differences in metastatic disease and prostate cancer death.Results: We analysed 302 patients with complete follow-up during a median of 18 years. Median preoperative PSA was 9.8 ng/ml and median age at inclusion was 65 years. For patients without biochemical recurrence 5 years after radical prostatectomy the 20-year probability of biochemical recurrence was 25% among men with Gleason score ≤3+4=7 and 57% among men with Gleason score ≥4+3=7; the probabilities for metastases were 0.8% and 17%; and for prostate cancer death 0.8% and 12% respectively. The long-term probabilities were higher for pT≥3 vs. pT2 and for positive vs. negative surgical margins.Conclusions: Following radical prostatectomy, patients with Gleason score ≤3+4=7 without biochemical recurrence 5 years after radical prostatectomy had low risk of metastases and prostate cancer death independent of pT-stage and surgical margins. The risk of clinical progression decreased drastically the first 3 years after radical prostatectomy and after 10 years without biochemical recurrence, no patient was diagnosed with metastases or died from prostate cancer. Our study indicates that men with favourable histopathology without biochemical recurrence 5 years after radical prostatectomy can stop follow-up earlier than 10 years after radical prostatectomy while men with adverse pathology should continue with at least 10 years follow-up

- Frequent consumption of meat has been associated with an increased risk of colorectal cancer. Such a risk may be due to naturally occurring compounds in the meat, substances added to the meat, or agents formed during cooking. Concerning the latter alternative, mutagenic heterocyclic amines are multi-site animal carcinogens, but their relevance to human cancer has yet to be determined. In the present study, we made a population-based inventory of cooked meat dishes consumed in the county of Stockholm, ranked dishes according to cooking method and frequency of consumption and, in addition, determined levels of mutagenic activity in six commonly consumed fried meat dishes. Meat was consumed, on average, 493 times per year, giving 1.4 daily servings. Frying was the most common way to cook meat. When ranking meat dishes according to intake frequency, the top eight dishes were as follows. sausage, steak casserole, meatballs, pork chops, pork belly, bacon, ground beef patties, and, finally, mincemeat sauce. The frying sessions were pel;formed under controlled conditions at four different temperatures, and we documented the degree of surface browning and measured mutagenic activity in six frequently eaten dishes (sausage, meatballs, pork chops, pork belly, ground beef patties, and minute beef). We found extracts from all six dishes to be mutagenic, and a mean daily dose of exposure was calculated, giving 862 revertants. This investigation leaves no doubt that a major portion of the total meat consumption is fried before ingestion and that fried meat dishes frequently consumed by an elderly population in Stockholm contain mutagenic substances. Furthermore, the study provides usable information for future epidemiological research in which it is necessary to disentangle the effect of meat per se from the effect of potentially carcinogenic heterocyclic amines.

- Heterocyclic amines are possible human carcinogens and fried meat is an important source of exposure in the Western diet, To study the effect of heterocyclic amines in humans, accurate assessment of individual food consumption is essential, Parameters influencing the intake include the amount and type of meat ingested, frequency of consumption, cooking method, cooking temperature and the duration of cooking, The aim of the present study was to develop a practical method for assessing individual intakes of specific heterocyclic amines in a large sample of people, This has been done by combining information on food consumption and laboratory findings of heterocyclic amines in food products, Diet was assessed using a semi-quantitative food frequency questionnaire including photos of fried meat and, in all, 22 dishes were cooked and chemically analyzed. The method was employed in an elderly population in Stockholm to estimate the daily mean intake of the five heterocyclic amines 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), 2-amino-3,4-dimethylimidazo [4,5-f]quinoline (MeIQ), 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-3,4,8-trimethylimidazo [4,5-f]quinoxaline (DiMeIQx) and 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), The total daily intake ranged from none to 1816 ng, with a mean intake of 160 ng, which is well below estimates reported previously, Highest amounts ingested were of PhIP (mean 72, range 0-865 ng/day) and MeIQx (mean 72, range 0-1388 ng/day), followed by DiMeIQx (mean 16, range 0-171 ng/day), while MeIQ and IQ were ingested only in very small amounts (mean <1 ng/day).

- Background Heterocyclic amines formed in cooked meat and fish are carcinogenic in animal models and form DNA adducts in human beings. We undertook a study to assess whether these substances are related to the risks of cancer in the large bowel and urinary tract. Methods In a population-based case-control study, cases were identified from the Swedish cancer registry. Controls were randomly selected from the population register. Information on intake of various foods and was assessed by questionnaire, with photographs of foods cooked at various temperatures. We measured the content of heterocyclic amines in foods cooked under these conditions. Findings Information was retrieved from 553 controls, 352 cases of colon cancer, 249 cases of rectal cancer, 273 cases of bladder cancer, and 138 cases of kidney cancer. The response rate was 80% for controls and 70% for cases. The estimated daily median intake of heterocyclic amines was 77 ng for controls, and 66 ng, 63 ng, 96 ng, and 84 ng for cases with cancer of the colon, rectum, bladder, and kidney, respectively. The relative risk for the intake of heterocyclic amines (highest vs lowest quintile) was 0.6 (95% CI 0.4-1.0) for colon cancer, 0.7 (0.4-1.1) for rectal cancer, 1.2 (0.7-2.1) for bladder cancer, and 1.0 (0.5-1.9) for kidney cancer. Seven cases, but no controls, had an estimated daily intake of heterocyclic amines above 1900 ng. Interpretation Intake of heterocyclic amines, within the usual dietary range in this study population, is unlikely to increase the incidence of cancer in the colon, rectum, bladder, or kidney. For daily intakes above 1900 ng, our data are consistent with human carcinogenicity, but the precision was extremely low.
