- 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

- 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.

- Introduction & Objectives: To assess the rate of postoperative infectious and thromboembolic complications associated with inguinal (ILND) and pelvic (PLND) lymph node dissection in penile cancer and identify clinical and pathological predictors for the development of these complications.Materials & Methods: A total of 364 men subjected to ILND with or without PLND for squamous cell carcinoma of the penis between 2000 and 2012 were identified through the Swedish National Penile Cancer Register. Each patient was matched based on age and county of residence with 6 penile cancer-free men. The Swedish cancer and population registers were used to retrieve information about treatment and hospitalization for infections of the lower limbs, groins, genitalia, trunk and various septic conditions as well as thromboembolic events based on ICD-10 codes for each event. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using Cox proportional hazard models with multiple imputation to assess the effects of different variables. The net hazard rates of outcomes were estimated using a flexible parametric model.Results: The risk to suffer from infectious events remained increased up to 6 years postoperatively in penile cancer patients who underwent ILND in comparison to the matched controls. Palpable nodal disease was the only predictor of increased risk of infectious complications. The risk tends to increase with the cN stage, with a HR of 1.65 (95% CI 0.98-2.77) for cN1, 1.93 (95% CI 1.14-3.29) for cN2 and 2.62 (95% CI 1.41-4.88) for cN3 disease. Risks for the first, third and sixth postoperative year were assessed with HRs of 8.87 (95% CI 5.36-14.66), 4.20 (95% CI 2.77-6.35) and 1.83 (95% CI 0.96-3.46) respectively. The increased risk of thromboembolic events persisted up to 3 years postoperatively, HRs for the first and third postoperative year were 13.51 (95% CI 6.53-27.93) respectively 2.12 (95% CI 1.07-4.20). The results correspond well with the over-prescription of anticoagulants observed during this period. An association with bulky disease was observed, with a HR of 3.81 (95% CI 1.10-13.17) for cN3 stage. PLND did not add any excessive risks for either infectious or thromboembolic events.Conclusions: Based on data from nationwide registers of high quality and completeness, we could assess postoperative morbidity after lymphadenectomy for penile cancer with follow-up length ranging up to 12 years. Patients with palpable nodal disease are at increased risk of infectious complications up to 6 years postoperatively. The risk of thromboembolic complications was increased during first 3 postoperative years. Patients and care givers need to be aware of the increased risk of these complications and preventive measures should be considere

- 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.

- Context: Testicular cancer patients are often diagnosed at a young age, and because of the advances in the treatment of this disease, the vast majority have a normal life expectancy after therapy. Thus, recognition of the long-term sequelae of treatment (ie, surgery, radiation therapy, and chemotherapy) is particularly important in these patients. Objective: To review the adverse effects and the risk of secondary malignancy in long-term survivors of testicular cancer. Evidence acquisition: We conducted a Medline search to identify original articles and reviews on the long-term effects of testicular cancer treatment. Although the search included articles from January 1948 to February 2011, the majority of the included articles were published in the last two decades. Evidence synthesis: All studies examining the long-term sequelae of treatment in testicular cancer are retrospective in nature, with most classified as cohort, case-control, and/or epidemiologic studies. Given that no standardized method of reporting long-term complications exists, evidence synthesis is limited. Conclusions: Recent evidence suggests an increased risk of cardiovascular disease, neurotoxicity, and mild reductions in renal function in survivors of testicular cancer. Treatment of testicular malignancy can also negatively affect gonadal function and fertility and has been shown to result in an increased risk of solid malignancy and leukemia.

Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: The well-known side-effect profile of androgen-deprivation therapy (ADT) has significant quality-of-life (QoL) implications. Intermittent androgen deprivation (IAD) alternates androgen blockade with treatment cessation to allow hormonal recovery between treatment cycles, thus potentially improving tolerability and QoL. OBJECTIVE: To evaluate available evidence regarding the efficacy and tolerability of IAD and assess its value in the treatment of prostate cancer (PCa). EVIDENCE ACQUISITION: Key phase 2/3 clinical trials of IAD in PCa published within the last 10 yr were identified on Medline using the terms prostatic neoplasms [MeSH], intermittent androgen suppression, intermittent hormonal deprivation, intermittent androgen deprivation, and intermittent hormonal therapy. Abstracts from trials reported at 2008-2009 conferences were also included. EVIDENCE SYNTHESIS: Data from 19 phase 2 studies are discussed with respect to prostate-specific antigen values for treatment suspension/reinitiation, treatment regimens, cycle lengths, testosterone normalisation, and tolerability. Outcome data were promising: Most trials reported an improvement in QoL during the off-therapy periods. Interim data from eight phase 3 trials comparing IAD and continuous androgen deprivation (CAD) support the phase 2 results. IAD generally showed comparable efficacy to CAD with respect to various outcomes, including biochemical progression, progression-free survival, and overall survival. However, IAD was significantly better than CAD with respect to 3-yr risk of progression in one study, and it demonstrated tolerability benefits, particularly with respect to sexual function. Patients most likely to benefit from IAD and factors predictive of poor response are also discussed. CONCLUSIONS: IAD seems to be as effective as CAD while showing tolerability and QoL advantages, especially recovery of sexual potency; however, there are as yet insufficient data to determine whether IAD has the potential to prevent or reverse the long-term complications associated with ADT.
