- Objective: At presentation of prostate cancer, patients with proven lymph node metastasis (N1) are comparatively rare. It is difficult to give prognostic information based on the present literature. The aim of this study was to evaluate the impact of known risk factors in patients with pelvic node involvement and without distant metastasis. Methods: From the population-based, prospective prostate cancer tumour registry of the South–East Region in Sweden, we collected data on all 181 patients with N1, M0 prostate cancer diagnosed from January 1987 to October 2000 with a follow-up to December 2001. Mean follow-up was 62 months. Pre-operative risk factors as age, T-category, serum PSA, tumour grade and also primary treatment given was correlated to the outcome. Results: Median age at diagnosis was 65 years. Cancer-specific survival was highly variable with 5-year survival of 72%, a median of 8 years and the projected 13-year figure was 31%. T-category, age, PSA or treatment did not affect the outcome while poorly differentiated tumours had a tendency towards lower cancer-specific survival (p=0.0523) when compared to well and moderately differentiated tumours. Conclusions: This population-based cohort of prostate cancer patients with pelvic node involvement treated principally with non-curative intent had a median cancer-specific survival of 8 years. Preoperatively known risk factors seem to have but a modest impact on the prognosis for patients in this stage of the disease.

- 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 the cumulative risk of having a prostate cancer diagnosis in a repeated screening situation in relation to the free-to-total prostate specific antigen ratio (F/T-PSA). Patients and Methods: The present study includes 1385 men (aged 50-70 years) who underwent prostate biopsy for the first time in the screening program that started in 1995. In case of a benign finding, the men have been followed biennially and new biopsies performed in case of persistently elevated PSA. The cumulative risk to be diagnosed with prostate cancer until July 1, 2002 was calculated by the Kaplan-Meier method and comparison was made between different levels of T-PSA and F/T-PSA ratios. Results: Of 2129 biopsies 469 showed cancer. The cumulative 5-year risk to be diagnosed with prostate cancer was significantly dependent of the F/T-ratio. The risk for men with a T-PSA of 3-5.99 ng/ml was 16% [6-25%] for those who had a ratio of >30% and 44% [34-60%] for those with a ratio of <10%. The corresponding difference for patients with a T-PSA of 6-9.99 ng/ml was even more pronounced: 21% [0-42%] vs. 80% [64-96%]. Conclusion: By completing the T-PSA measurement with the F/T-PSA ratio it is possible to significantly better assess the cumulative prostate cancer risk within the next five years (without the aid of further urological work-up).

Clinical consequences of screening for prostate cancer : 15 Years follow-up of a randomised controlled trial in Sweden

Tidskriftsartikel (refereegranskat)abstract
- Objective:To test the feasibility of a population-based prostate cancer screening programme in general practice and explore the outcome after a 15-year follow-up period.Methods:From the total population of men aged 50–69 years in Norrköping (n = 9026) every sixth man (n = 1494) was randomly selected to be screened for prostate cancer every third year over a 12-year period. The remaining 7532 men were treated as controls. In 1987 and 1990 only digital rectal examination (DRE) was performed, in1993 and 1996 DRE was combined with a test for Prostate-Specific Antigen (PSA). TNM categories, grade of malignancy, management and cause of death were recorded in the South-East Region Prostate Cancer Register.Results:There were 85 (5.7%) cancers detected in the screened group (SG), 42 of these in the interval between screenings, and 292 (3.8%) in the unscreened group (UG). In the SG 48 (56.5%) of the tumours and in the UG 78 (26.7%) were localised at diagnosis (p < 0.001). In the SG 21 (25%) and in the UG 41 (14%) received curative treatment. There was no significant difference in total or prostate cancer-specific survival between the groups.Conclusions:Although PSA had not been introduced in the clinical practice at the start of the study, we were still able to show that it is possible to perform a long-term population-based randomised controlled study with standardised management and that screening in general practice is an efficient way of detecting prostate cancer whilst it is localised. Complete data on stage, treatment and mortality for both groups was obtained from a validated cancer register, which is a fundamental prerequisite when assessing screening programmes.
