- Purpose In this prospective cohort study, the effects of hyperbaric oxygen treatment (HBOT) were evaluated concerning patient-perceived symptoms of late radiation-induced cystitis and proctitis secondary to radiation therapy for pelvic cancer. Methods and Materials Thirty-nine patients, 35 men and 4 women with a mean age of 71 (range, 35-84) years were included after informed consent and institutional ethics approval. They had all been treated with radiation therapy for prostate (n=34), cervix (n=2), or rectal (n=3) cancer using external beam radiation at a dose of 25 to 75 Gy. Patients with hematuria requiring blood transfusion were excluded. The HBOT was delivered with 100% oxygen for 90 minutes at 2.0 to 2.4 atmospheres (ATA). Mean number of treatments was 36 (28-40). Symptoms were prospectively assessed using the Expanded Prostate Index Composite score before, during, and 6 to 12 months after HBOT. Results The HBOT was successfully conducted, and symptoms were alleviated in 76% for patients with radiation cystitis, 89% for patients with radiation proctitis, and 88% of patients with combined cystitis and proctitis. Symptom reduction was demonstrated by an increased Expanded Prostate Index Composite score in the urinary domain from 50 ± 16 to 66 ± 20 after treatment (P<.001) and in the bowel domain from 48 ± 18 to 68 ± 18 after treatment (P<.001). For 31% of the patients with cystitis and 22% with proctitis, there were only trivial symptoms after HBOT. The improvement was sustained at follow-up in both domains 6 to 12 months after HBOT. No severe side effects were observed related to HBOT, and treatment compliance was high. Conclusions HBOT can be an effective and safe treatment modality for late radiation therapy-induced soft tissue injuries in the pelvic region. © 2013 Elsevier Inc.

- © 2019 Elsevier Ltd Background: Late radiation cystitis is an adverse effect of cancer treatment with radiotherapy in the pelvic region. Symptoms of late radiation cystitis can be assessed with the Expanded Prostate Index Composite Score (EPIC). Previous reports indicate that hyperbaric oxygen therapy reduces symptoms from late radiation cystitis, but the evidence is predominantly based on non-randomised and retrospective studies. We aimed to assess whether hyperbaric oxygen therapy would mitigate symptoms of late radiation cystitis. Methods: We did a randomised, controlled, phase 2–3 trial (RICH-ART [Radiation Induced Cystitis treated with Hyperbaric oxygen—A Randomised controlled Trial]) at five Nordic university hospitals. All patients aged 18–80 years, with pelvic radiotherapy completed at least 6 months previously, a score of less than 80 in the urinary domain of the Expanded Prostate Index Composite Score (EPIC), and referred to participating hyperbaric clinics due to symptoms of late radiation cystitis, were eligible for inclusion. Exclusion criteria were ongoing bleeding requiring blood transfusion exceeding 500 mL in the past 4 weeks, permanent urinary catheter, bladder capacity less than 100 mL, fistula in the urinary bladder, previous treatment with hyperbaric oxygen therapy for late radiation injuries, and contraindications to hyperbaric oxygen therapy. After computer-generated 1:1 randomisation with block sizes of four for each stratification group (sex, time from radiotherapy to inclusion, and previous invasive surgery in the pelvic area), patients received hyperbaric oxygen therapy (30–40 sessions, 100% oxygen, breathed at a pressure of 240–250 kPa, for 80–90 min daily) or standard care with no restrictions for other medications or interventions. No masking was applied. The primary outcome was change in patient-perceived urinary symptoms assessed with EPIC from inclusion to follow-up at visit 4 (6–8 months later), measured as absolute change in EPIC urinary total score. RICH-ART closed enrolment on Dec 31, 2017; the last follow-up data will be compiled in 2023. RICH-ART is registered with ClinicalTrials.gov, number NCT01659723, and with the European Medicines Agency, number EudraCT 2012-001381-15. Findings: Of 223 patients screened between May 9, 2012, and Dec 20, 2017, 87 patients were enrolled and randomly assigned to either hyperbaric oxygen therapy (n=42) or standard care (n=45). After excluding eight patients who withdrew consent directly after randomisation (one in the hyperbaric oxygen therapy group and seven in the standard care group), 79 were included in the intention-to-treat analyses (n=41 in the hyperbaric oxygen therapy group, n=38 in the standard care group). Median time from randomisation to visit 4 was 234 days (IQR 210–262) in the hyperbaric oxygen therapy group and 217 days (195–237) in the standard care group. The difference between change in group mean of EPIC urinary total score at visit 4 was 10·1 points (95% CI 2·2–18·1; p=0·013; 17·8 points [SD 18·4] in the hyperbaric oxygen therapy group vs 7·7 points [15·5] in the standard care group). 17 (41%) of 41 patients in the hyperbaric oxygen therapy group experienced transient grade 1–2 adverse events, related to sight and hearing, during the period of hyperbaric oxygen therapy. Interpretation: Our results suggest that hyperbaric oxygen therapy relieves symptoms of late radiation cystitis. We conclude that hyperbaric oxygen therapy is a safe and well tolerated treatment.

- Purpose: The demand for objective and outcome-based facts about surgical results after radical prostatectomy (RP) is increasing. Systematic feedback is also essential for each surgeon to improve his/her performance. Methods: RP outcome data (e.g., pT-stage and margin status) have been registered at Sahlgrenska University Hospital (SUH) since 1988 and patient-related outcome measures (PROM) have been registered since 2001. The National Prostate Cancer Registry (NPCR) has covered all Regions in Sweden since 1998 and includes PROM-data from 2008. Initially PROM was on-paper questionnaires but due since 2018 all PROMs are collected electronically. In 2014 an on-line “dashboard” panel was introduced, showing the results for ten quality-control variables in real-time. Since 2017 all RP data on hospital, regional, and national levels are publicly accessible on-line on “www.npcr.se/RATTEN”. Results: The early PROM-data from SUH have been used for internal quality control. As national clinical and PROM-data from the NPCR have been made accessible on-line and in real-time we have incorporated this into our pre-existing protocol. Our data are now internally available as real-time NPCR reports on the individual surgeons’ results, as well as ePROM data. We can compare the results of each surgeon internally and to other departments’ aggregated data. The public can access data and compare hospital level data on “RATTEN”. Conclusions: The process of quality control of RP locally at SUH, and nationally through the NPCR, has been long but fruitful. The online design, with direct real-time feedback to the institutions that report the data, is essential.

Tidskriftsartikel (refereegranskat)abstract
- Abstract Objectives Randomized controlled trials are currently conducted to assess whether the mortality from prostate cancer is reduced by early detection with the use of prostate-specific antigen (PSA) measurements in serum. To be effective, such a program should be able to reduce the absolute number of men diagnosed with metastatic prostate cancer (for which no cure is available). The aim of the present report is to evaluate whether PSA-based screening reduces the risk of being diagnosed with metastatic prostate cancer. Methods A population-based, prospective, randomized, controlled screening trial for prostate cancer started in 1995 (the Göteborg branch of the European Randomized Study of Screening for Prostate Cancer [ERSPC]). Ten thousand, randomly selected men aged 50–66 yr were invited for biennial PSA testing, with 10,000 men serving as passive controls for whom diagnosis of metastatic prostate cancer was monitored by using the Swedish Cancer Registry. Results After a follow-up of 10 yr, the risk of being diagnosed with metastatic prostate cancer was reduced by 48.9%—that is, decreasing from 47 cases in the control group to 24 cases in the group randomized to PSA-based screening (p = 0.0084). However, the risk of being diagnosed with prostate cancer increased 1.8-fold with PSA-based screening. Conclusions Biennial PSA screening reduces the risk of being diagnosed with metastatic prostate cancer, the first prerequisite for achieving decreased cancer mortality in younger men. This putative benefit is balanced by a 1.8-fold increased risk for diagnosis of prostate cancer. Take Home Message The present randomized, controlled study shows that men taking part in a PSA-based prostate cancer–screening program will have a 50% reduction in the risk of being diagnosed with advanced/metastatic, noncurable prostate cancer.

The excess burden of side-effects from treatment in men allocated to screening for prostate cancer. The Göteborg randomised population-based prostate cancer screening trial.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The number of men needed to treat to prevent one death is rather high in prostate cancer screening. How this affects the burden of treatment-related side-effects is unclear. The aim of this study was to evaluate the treatment related morbidity following radical prostatectomy in men participating in the Göteborg randomised population-based prostate cancer screening trial. METHODS: In 1995, 20,000 men aged 50-64years were randomly allocated (1:1) to biennial PSA-screening or to a control group not invited. A subset of prostate cancer patients undergoing radical prostatectomy between 2001 and 2008 responded to questionnaires preoperatively and at 18months postoperatively. The primary endpoint was patient-reported frequencies of erectile dysfunction as measured by the validated International Index of Erectile Function-5 questionnaire and urinary incontinence as assessed by use of pads. Analyses were made according to intention to screen. FINDINGS: After 14years of follow-up, a total of 1849 men were detected with prostate cancer (1138 screened versus 711 controls, excluding 7 cancers detected at autopsy in the control group). Overall, 1047 received treatment with curative intent and radical prostatectomy was performed in 829 cases (79.2%). In this study, 294 of these men participated (205 screened and 89 controls). Of preoperatively potent men 79.1% (91/115) in the screening-group and 90.7% (49/54) in the control-group became impotent or sexually inactive 18months postoperatively, whereas 14.3% (29/203) of screened men and 20.5% (18/88) of controls were considered postoperatively incontinent (regular use of pads). Extrapolated data yields that 120/10,000 more men become impotent and 25/10,000 more men will have the need of pads among men invited to regular PSA screening. The 'cost' per life saved at the same follow-up of screening is four men impotent and less than one man incontinent. INTERPRETATION: Despite the relatively high risk of erectile dysfunction and incontinence following radical prostatectomy for prostate cancer, the excess burden of permanent side-effects after population-based screening can be regarded as relatively low, when related to the number of men saved from prostate cancer death. These data can be useful when calculating the harms and benefits of screening. However, the outcome on a population-level may differ from the benefit for the individual.

Tidskriftsartikel (refereegranskat)abstract
- Purpose:Our goal was to analyze results from 22 years of followup in the Göteborg randomized prostate cancer (PC) screening trial.Materials and Methods:In December 1994, 20,000 men born 1930-1944 were randomly extracted from the Swedish population register and were randomized (1:1) into either a screening group (SG) or to a control group (CG). Men in the SG were repeatedly invited for biennial prostate specific antigen testing up to an average age of 69 years. Main endpoints were PC incidence and mortality (intention-to-screen principle).Results:After 22 years, 1,528 men in the SG and 1,124 men in the CG had been diagnosed with PC. In total, 112 PC deaths occurred in the SG and 158 in the CG. Compared with the CG, the SG showed a PC incidence rate ratio (RR) of 1.42 (95% CI, 1.31-1.53) and a PC mortality RR of 0.71 (95% CI, 0.55-0.91). The 22-year cumulative PC mortality rate was 1.55% (95% CI, 1.29-1.86) in the SG and 2.13% (95% CI, 1.83-2.49) in the CG. Correction for nonattendance (Cuzick method) yielded a RR of PC mortality of 0.59 (95% CI, 0.43-0.80). Number needed to invite and number needed to diagnose was estimated to 221 and 9, respectively. PC death risk was increased in the following groups: nontesting men, men entering the program after age 60 and men with >10 years of followup after screening termination.Conclusions:Prostate specific antigen-based screening substantially decreases PC mortality. However, not attending, starting after age 60 and stopping at age 70 seem to be major pitfalls regarding PC death risk.

- Objective: This study examined whether previously reported results, indicating that prostate-specific antigen (PSA) screening can reduce prostate cancer (PC) mortality regardless of sociodemographic inequality, could be corroborated in an 18 year follow-up. Materials and methods: In 1994, 20,000 men aged 50–64 years were randomized from the Göteborg population register to PSA screening or control (1:1) (study ID: ISRCTN54449243). Men in the screening group (n = 9950) were invited for biennial PSA testing up to the median age of 69 years. Prostate biopsy was recommended for men with PSA ≥2.5 ng/ml. Last follow-up was on 31 December 2012. Results: In the screening group, 77% (7647/9950) attended at least once. After 18 years, 1396 men in the screening group and 962 controls had been diagnosed with PC [hazard ratio 1.51, 95% confidence interval (CI) 1.39–1.64]. Cumulative PC mortality was 0.98% (95% CI 0.78–1.22%) in the screening group versus 1.50% (95% CI 1.26–1.79%) in controls, an absolute reduction of 0.52% (95% CI 0.17–0.87%). The rate ratio (RR) for PC death was 0.65 (95% CI 0.49–0.87). To prevent one death from PC, the number needed to invite was 231 and the number needed to diagnose was 10. Systematic PSA screening demonstrated greater benefit in PC mortality for men who started screening at age 55–59 years (RR 0.47, 95% CI 0.29–0.78) and men with low education (RR 0.49, 95% CI 0.31–0.78). Conclusions: These data corroborate previous findings that systematic PSA screening reduces PC mortality and suggest that systematic screening may reduce sociodemographic inequality in PC mortality.

- Prostate cancer is one of the leading causes of death from malignant disease among men in the developed world. One strategy to decrease the risk of death from this disease is screening with prostate-specific antigen (PSA); however, the extent of benefit and harm with such screening is under continuous debate.

- PURPOSE: We evaluated whether biennial screening with prostate specific antigen (PSA) only is sufficient to detect prostate cancer while still curable. MATERIALS AND METHODS: In Goteborg, Sweden 9,972 men 50 to 65 years old were randomized to PSA screening. During 1995 and 1996 these men were invited for a first PSA screening and invited during 1997 and 1998 for a second screening. The screening procedure included PSA measurement in all men and in those with a PSA of 3 ng./ml. or greater also it included digital rectal examination, transrectal ultrasound and sextant biopsies. RESULTS: In the first screening 5,854 men participated and 145 cancers were detected. In the second screening 5,267 men participated and 111 cancers were detected. Only 9 interval cancers were diagnosed. In the second screening 102 cancers (92%) were associated with PSA less than 10 ng./ml. Of 465 men with increased PSA and who underwent biopsy with a benign outcome in the first screening 50 had cancer at the second screening. Of 241 men in whom PSA increased between screenings 1 and 2 cancer was detected in 46. None of the 2,950 men with an initial PSA of less than 1 ng./ml. had a PSA of greater than 3 ng./ml. or interval cancer. CONCLUSIONS: In men with a PSA of less than 2 ng./ml. it seems safe to offer repeat screening after 2 years with PSA only. Men with a PSA of 2 to 3 ng./ml. or a value of greater than 3 ng./ml. with negative biopsy may be better served by a shorter screening interval. Thus, different screening intervals are implied depending on baseline PSA.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The Early Prostate Cancer (EPC) programme is evaluating the efficacy and tolerability of bicalutamide following standard care (radiotherapy, radical prostatectomy or watchful waiting) in patients with localized (T1-2, N0/Nx) or locally advanced (T3-4, any N; or any T, N + ) non-metastatic prostate cancer. Herein we report the latest findings after a median follow-up period of 7.1 years from the Scandinavian Prostate Cancer Group (SPCG)-6 study, one of three trials in the EPC programme. MATERIAL AND METHODS: A total of 1218 patients were randomized on a 1:1 basis to either bicalutamide 150 mg/day (n=607) or placebo (n=611) following standard care; 81.4% were followed conservatively (watchful waiting). The primary endpoints were objective progression-free survival (PFS) and overall survival (OS). RESULTS: In patients with localized disease there was no significant difference in PFS [hazard ratio (HR) 0.85; 95% CI 0.69-1.06; p=0.15] and a trend towards decreased OS with bicalutamide plus standard care compared with standard care alone (HR 1.23; 95% CI 0.96-1.58; p=0.11). In patients with locally advanced disease, bicalutamide significantly improved PFS, reducing the risk of progression by 53% compared with standard care alone (HR 0.47; 95% CI 0.37-0.59; p<0.001). The median time to progression was 8.8 years for bicalutamide plus standard care and 7.1 years for standard care alone. There was a significant improvement in OS with bicalutamide plus standard care, with a reduction in the risk of death of 35% versus standard care alone (HR 0.65; 95% CI 0.50-0.85; p=0.001). CONCLUSION: This analysis of the SPCG-6 study showed that bicalutamide plus standard care offers significant PFS and OS benefits for patients with locally advanced disease, but not for those with localized disease.

Inguinal hernia after radical retropubic prostatectomy: risk factors and prevention.

Tidskriftsartikel (refereegranskat)abstract
- The two most frequently occurring and well-described complications of radical retropubic prostatectomy (RRP) for prostate cancer are incontinence and impotence. Inguinal hernia (IH) has, over the last decade, emerged as an additional complication, with an estimated incidence of 15-20% after RRP. IH is a common lesion in men aged between 50 and 70 years with or without prostate cancer, and the literature indicates that annual incidence is somewhere between 0.5% and 1% in the general male population. Important risk factors for the development of post-RRP IH are previous IH surgery, increasing age, and low BMI. However, subclinical IH at the time of RRP and a lower midline incision seem to be the most important causative factors. Prophylactic procedures and, in the case of clinically detectable IH lesions, concurrent repair during RRP are advocated. Reports on alternative approaches to RRP, such as minilaparotomy RRP, laparoscopic radical prostatectomy (including robot-assisted procedures) and radical perineal prostatectomy have indicated low rates of postoperative IH. The risk of developing IH after prostatectomy should be part of the preoperative risk assessment when making treatment decisions for patients with prostate cancer.

- Objectives To analyze the incidence of inguinal hernia (IH) in a large group of patients with nonmetastatic prostate cancer who were treated nonoperatively, and to compare it with the incidence in a subset of patients who had undergone radical retropubic prostatectomy (RRP). IH has been reported in 12% to 21% of men at a mean period of 6 to 10 months after RRP. However, whether IH truly represents a complication after RRP has been somewhat debatable owing to the lack of proper control groups. Methods A total of 953 patients treated without surgery (nonoperative group) and 152 patients who underwent RRP (operative group) were selected from the Scandinavian Prostate Cancer Group Study No. 6 database consisting of 1218 patients with nonmetastatic prostate cancer. Radiotherapy, cryotherapy, and a follow-up duration of less than 3 months were exclusion criteria. Patients were followed up for any new medical condition at 12-week intervals for a mean period of 39 months (nonoperative group) and 50 months (operative group). Results Of the 953 patients in the nonoperative group, 23 (2.4%) developed IH versus 13 (8.6%) of 152 in the operative group (log-rank [Mantel-Cox] P = 0.010). Conclusions Within comparable age groups, the incidence of IH in men with prostate cancer treated without surgery was significantly lower than that after RRP. This phenomenon seems to be causally related to the surgical procedure. The increased risk of IH after RRP deserves further recognition and should be included in the preoperative information given to patients. Studies are warranted to define the causal mechanisms, as well as possible preventive measures.

- Inguinal hernia is a known complication after radical retropubic prostatectomy (RRP). We have investigated whether other types of lower midline incision surgery in males increase the risk of inguinal hernia. Male patients operated with open prostatectomy for benign prostate hyperplasia (n = 95), pelvic lymph node dissection for staging of prostate cancer (n = 88), or cystectomy for bladder cancer (n = 76) were identified and were sent questionnaires in which they were asked about postoperative inguinal hernia morbidity. Two-hundred and seventy-one men operated with RRP had previously received a similar questionnaire. The answers were compared with those from a control group of 953 men who had not undergone surgery. Annual attributional hernia morbidity and Kaplan–Meier hernia-free survival were calculated. The cumulative incidence of post-operative inguinal hernia and annual attributional hernia morbidity after the respective surgical procedures were clearly higher during the early years post-operation than for nonoperated patients. Inguinal hernia is a common postoperative complication in males after all the lower midline incision surgery investigated.

- Purpose Inguinal hernia after radical retropubic prostatectomy has been reported to occur in 7% to 21% of patients. We analyzed the impact of simultaneous pelvic lymph node dissection, preoperative inguinal hernia morbidity, postoperative anastomotic stricture, duration of surgery and patient age. We also compared the detection rate of inguinal hernia events in a retrospective patient file survey to that in a prospective patient administered questionnaire. Materials and Methods A total of 498 patients underwent radical retropubic prostatectomy plus pelvic lymph node dissection and 166 underwent radical retropubic prostatectomy only. Mean followup was 40 months (median 37, range 3 to 85). All 664 patients were analyzed in the patient file survey. The patient administered questionnaire was mailed preoperatively, and after 3, 6, 12, 18, 24 and 36 months to 271 patients who underwent operation between 2001 and 2002. A total of 207 patients (76.4%) completed the preoperative questionnaire. Results The cumulative incidence of inguinal hernia after 24 months was 11.6% in the patient file survey and 15.7% in the patient administered questionnaire. In the patient file survey patient age was the only studied factor that significantly influenced risk. The patient file survey failed to detect half of the men with preoperative inguinal hernia morbidity and a third of post-radical retropubic prostatectomy inguinal hernias compared to the patient administered questionnaire. On patient administered questionnaire analysis preoperative inguinal hernia morbidity was a significant risk factor for postoperative inguinal hernia (log rank Mantel-Cox test p = 0.010). Conclusions Previous inguinal hernia morbidity and age increase the risk of post-radical retropubic prostatectomy inguinal hernia. Simultaneous pelvic lymph node dissection, postoperative anastomotic stricture and duration of surgery were not significant risk factors in this study. The patient file survey is inferior to the patient administered questionnaire for detecting inguinal hernia events.

- Abstract Objective: To evaluate a new prophylaxis routine, which was introduced at our clinic in December 1998, comprising a single oral dose of antibiotic given prior to radical retropubic prostatectomy (RRP). Material and Methods: A total of 60 men scheduled to undergo RRP were included in a prospective study and received antibiotic prophylaxis in the form of a single oral dose of quinolone. Cultures were made from the tip of the catheter and from urine sampled at the time of extraction as well as 1 and 2 weeks post-extraction. The outcome of this prospective study of 60 men was then compared to the total numbers of patients operated on in 1998 (n = 103) and 1999 (n = 140) by means of a retrospective analysis of clinical files. Results: No cases of sepsis occurred. Two weeks after catheter removal, 15/60 patients had persisting bacteriuria. No other signs of infection were detected. Six patients developed a stricture of the anastomotic area during follow-up (mean duration 18.9 months). When the study group was compared to all patients operated on in 1998 and 1999 no increases in the incidence of anastomotic strictures or serious infections or in the length of hospitalization could be detected. Conclusion: A single dose of antibiotic given before RRP appears to be sufficient prophylaxis.

- Purpose To evaluate the efficacy and tolerability of prophylactic breast irradiation in reducing the incidence and severity of bicalutamide-induced gynecomastia and breast pain. Methods and materials In all, 106 men with prostate cancer (T1b–T4/Nx/M0) and no current gynecomastia/breast pain were enrolled in this randomized, sham-controlled, double-blind, parallel-group multicenter trial. Patients received either a single dose of electron beam radiotherapy (10 Gy) or sham radiotherapy. Bicalutamide (Casodex) 150 mg/day was administered for 12 months from the day of radiotherapy. Every 3 months, patients underwent physical examination and questioning about gynecomastia and breast pain. Results The incidence of investigator-assessed gynecomastia was significantly lower with radiotherapy vs. sham radiotherapy (52% vs. 85%; odds ratio [OR], 0.13; 95% confidence interval [CI], 0.04, 0.38; p < 0.001); direct questioning showed similar results. Fewer radiotherapy patients had ≥5 cm gynecomastia (measured by calipers; 11.5% vs. 50.0% for sham radiotherapy), and fewer cases were moderate-to-severe in intensity (21% vs. 48%). Similar proportions of radiotherapy and sham radiotherapy patients experienced breast pain (83% vs. 91%; OR, 0.25; 95% CI, 0.05, 1.27; p = 0.221); patients receiving radiotherapy experienced some reduction in its severity (OR, 0.44; 95% CI, 0.20, 0.97; p = 0.0429). Conclusions Prophylactic breast irradiation is an effective and well-tolerated strategy for prevention of bicalutamide-induced gynecomastia.
