- Operationsresultat redovisas för män opererade med radikal prostatektomi – öppen kirurgi jämfört med robotassisterad laparaskopi – under 2002–2006 vid Karolinska universitetssjukhuset, Solna. Män som följdes under minst 1 år besvarade enkätfrågor; 768 robotkirurgiska och 411 öppenkirurgiska operationer utvärderades. Under perioden minskade andelen män med positiv resektionsrand från 37 procent till 22 procent och med erektil dysfunktion från 66 procent till 60 procent. Andelen optimala operationsresultat (»trifecta«) ökade från 19 procent till 28 procent. Vi har inte hittat några indikationer på att införandet av robotkirurgi har försämrat situationen för män diagnostiserade med prostatacancer. Vi kan inte avgöra om de positiva operationsresultaten skulle ha blivit bättre eller sämre om ett utvecklingsprogram för öppen radikal prostatektomi i stället initierats. En nationell studie, LAPPRO, avseende effekterna av de två operationsformerna pågår.

- Objective: 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 of prostate cancer death. We investigated the long-term probabilities of PSA recurrence, metastases and prostate cancer death in patients without biochemical recurrence five and 10 years after radical prostatectomy.Design: Prospective cohort study. Stratification by Gleason score (<= 3+4=7or >= 4+3=7), pathological tumour stage (pT2 or >= pT3) and negative or positive surgical margins.Setting: Between 1989 and 1998, 14 urological centres in Scandinavia randomised patients to the Scandinavian Prostate Cancer Group study number 4 (SPCG-4) trial.ParticipationAll 306 patients from the SPCG-4 trial who underwent radical prostatectomy within 1year from inclusion were eligible. Four patients were excluded due to surgery-related death (n=1) or salvage radiotherapy or hormonal treatment within 6weeks from surgery (n=3).Primary outcome measures: 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 24 years. Median preoperative PSA was 9.8ng/mL and median age 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=7and 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 >= 3versus pT2 and for positive versus negative surgical margins. Limitations include small size of the cohort.Conclusion: Many patients with favourable histopathology without biochemical recurrence 5years after radical prostatectomy could stop follow-up earlier than 10 years after radical prostatectomy.

- We have developed a mobile phone application for measuring the intake of dietary fiber and validated the ability of the application to accurately capture this intake against measurements registered by a dietary record. We also investigated what food groups contributed most to the total, soluble, and insoluble dietary fiber intake. Twenty-six randomly selected Swedish women aged 35–85 years were included and randomized to either start to register dietary intake in the application or by a dietary record, during three consecutive days. After a washout period of at least two weeks, the participants used the other method. We found that the difference in measured mean fiber intake between the dietary record and the application was two grams independent of the total intake per day. A statistically significant correlation between fiber intake as measured by the two methods was found (rho = 0.65, p < 0.001). Vegetables and roots were the predominantly contributing foods to total and soluble fiber intake. Bread and crackers contributed most to insoluble fiber intake. In conclusion, the application may be considered as a useful and easy-to-use method to measure dietary fiber intake.

Tidskriftsartikel (refereegranskat)abstract
- Phytoestrogens have been suggested to have an anti-proliferative role in prostate cancer, potentially by acting through estrogen receptor beta (ERβ) and modulating several hormones. We primarily aimed to investigate the effect of a phytoestrogen intervention on hormone concentrations in blood depending on the ERβ genotype. Patients with low and intermediate-risk prostate cancer, scheduled for radical prostatectomy, were randomized to an intervention group provided with soybeans and flaxseeds (∼200 mg phytoestrogens/d) added to their diet until their surgery, or a control group that was not provided with any food items. Both groups received official dietary recommendations. Blood samples were collected at baseline and endpoint and blood concentrations of different hormones and phytoestrogens were analyzed. The phytoestrogen-rich diet did not affect serum concentrations of testosterone, insulin-like growth factor 1, or sex hormone-binding globulin (SHBG). However, we found a trend of decreased risk of increased serum concentration of estradiol in the intervention group compared to the control group but only in a specific genotype of ERβ (p = 0.058). In conclusion, a high daily intake of phytoestrogen-rich foods has no major effect on hormone concentrations but may lower the concentration of estradiol in patients with prostate cancer with a specific genetic upset of ERβ.

The effect of a phytoestrogen intervention and impact of genetic factors on tumor proliferation markers among Swedish patients with prostate cancer : study protocol for the randomized controlled PRODICA trial
- 2022
-
Ingår i: Trials. - : BioMed Central (BMC). - 1745-6215. ; 23:1

Tidskriftsartikel (refereegranskat)abstract
- Background: A high intake of phytoestrogens, found in soy, rye, and seeds, is associated with a reduced risk of a prostate cancer diagnosis. Previously, we found that the overall decreased risk of prostate cancer diagnosis in males with a high intake of phytoestrogens was strongly modified by a nucleotide sequence variant in the estrogen receptor-beta (ERβ) gene. However, we do not know if phytoestrogens can inhibit the growth of prostate cancer in males with established diseases. If there is an inhibition or a delay, there is reason to believe that different variants of the ERβ gene will modify the effect. Therefore, we designed an intervention study to investigate the effect of the addition of foods high in phytoestrogens and their interaction with the ERβ genotype on prostate tumor proliferation in patients with prostate cancer.Method: The PRODICA trial is a randomized ongoing intervention study in patients with low- and intermediate-risk prostate cancer with a Gleason score < 8, prostate-specific antigen (PSA) < 20, and scheduled for radical prostatectomy. The study is conducted at Sahlgrenska University Hospital in Gothenburg, Sweden. The intervention consists of a daily intake of soybeans and flaxseeds (~ 200 mg of phytoestrogens) until the surgery, approximately 6 weeks. The aim is to recruit 200 participants. The primary outcome is the difference in the proliferation marker Ki-67 between the intervention and the control groups. The genotype of ERβ will be investigated as an effect-modifying factor. Secondary outcomes include, e.g., concentrations of PSA and steroid hormones in the blood.Discussion: The results of the PRODICA trial will contribute important information on the relevance of increasing the intake of phytoestrogens in patients with prostate cancer who want to make dietary changes to improve the prognosis of their cancer. If genetic factors turn out to influence the effect of the intervention diet, dietary advice can be given to patients who most likely benefit from it. Dietary interventions are cost-effective, non-invasive, and result in few mild side effects. Lastly, the project will provide basic pathophysiological insights which could be relevant to the development of treatment strategies for patients with prostate cancer.Trial registration.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The aim of this randomized controlled trial was to evaluate the potential benefit from 2 probiotic bacteria of the species Lactiplantibacillus plantarum against radiation therapy-induced comorbidities. Methods and Materials: Women (>18 years of age) scheduled for radiation therapy because of gynecologic cancer were randomly allocated to consume placebo or either low-dose probiotics (1 pound 1010 colony-forming unit/capsule twice daily) or high-dose probiotics (5 pound 1010 colony-forming unit/capsule twice daily). The intervention started approximately 1 week before the onset of radiation therapy and continued until 2 weeks after completion. During this period the participants were daily filling in a study diary documenting the incidence and severity of symptoms, intake of concomitant medication, and stool consistency. The primary endpoint was the probiotic effect on the mean number of loose stools during radiation therapy. Results: Of the 97 randomized women, 75 provided data for the analysis of the results. The mean number of loose stools (sum of Bristol stool type 6 and 7) was not significantly reduced in the probiotic groups, but there was a significant reduction in the mean number of days with >1 loose stool with 15.04 +/- 8.92 days in the placebo and 8.65 +/- 5.93 days in the high-dose probiotics group (P = .014). The benefit was even more pronounced in the 2 weeks following the end of radiation therapy (P = .005). Moreover, intake of the probiotics resulted in a reduced severity of the symptoms grinding abdominal pain (P = .041) and defecation urgency (P = .08) and a reduced percentage of days with these symptoms (P = .023 and P = .042, respectively), compared with placebo. There were no differences regarding reported adverse events. Conclusions: Intake of the 2 probiotic bacteria was beneficial and reduced many measures or symptoms of the radiation-induced toxicity in women treated for gynecologic cancer. (c) 2022 The Authors.

- Objective To examine whether a method for raising women's awareness of fetal movements, Mindfetalness, can affect pregnancy outcomes. Design Cluster-randomised controlled trial. Setting Sixty-seven maternity clinics in Stockholm, Sweden. Population Women with singleton pregnancy with birth from 32 weeks' gestation. Methods Women registered at a clinic randomised to Mindfetalness were assigned to receive a leaflet about Mindfetalness (n = 19 639) in comparison with routine care (n = 20 226). Data were collected from a population-based register. Main outcome measures Apgar score <7 at 5 minutes after birth, visit to healthcare due to decrease in fetal movements. Other outcomes: Apgar score <4 at 5 minutes after birth, small-for-gestational-age and mode of delivery. Results No difference (1.1 versus 1.1%, relative risk [RR] 1.0; 95% CI 0.8-1.2) was found between the Mindfetalness group and the Routine care group for a 5-minute Apgar score <7. Women in the Mindfetalness group contacted healthcare more often due to decreased fetal movements (6.6 versus 3.8%, RR 1.72; 95% CI 1.57-1.87). Mindfetalness was associated with a reduction of babies born small-for-gestational-age (RR 0.95, 95% CI 0.90-1.00), babies born after gestational week 41(+6) (RR 0.91, 95% CI 0.83-0.98) and caesarean sections (19.0 versus 20.0%, RR 0.95; 95% CI 0.91-0.99). Conclusions Mindfetalness did not reduce the number of babies born with an Apgar score <7. However, Mindfetalness was associated with the health benefits of decreased incidence of caesarean section and fewer children born small-for-gestational-age. Tweetable abstract Introducing Mindfetalness in maternity care decreased caesarean sections but had no effect on the occurrence of Apgar scores <7.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The Radiumhemmets Scale of Disease-Specific Symptom Assessment-Prostate Cancer has been used in several studies. However, no test-retest reliability study of it has been conducted concerning the assessment of urinary, anal sphincter or large bowel function. The aim of this study was to evaluate the reliability of items assessing these functions. MATERIAL AND METHODS: We investigated 89 prostate cancer patients randomly selected from a group of patients diagnosed in Stockholm. The patients answered 24 questions assessing anal sphincter, large bowel and urinary function twice, with a 3-week interval in-between, to assess reliability. RESULTS: Most of the questions assessing bowel and urinary symptoms showed substantial or near-perfect agreement. The kappa value for bowel symptom items was > or = 0.60 for all items, except for defecation urgency (0.40-0.55). The kappa value for urinary symptom items varied between 0.43 and 1.0, except for urinary urgency (0.30-0.39). CONCLUSIONS: When comparing the impact of different symptoms of anal sphincter, large bowel or urinary tract dysfunction, it may be important to consider that defecation urgency and urinary urgency have the highest measuring error (low reliability). This error dilutes assessed associations with, for example, decreased quality of life. Nevertheless, the test-retest reliability for anal sphincter, large bowel and urinary symptoms indicates that surveys yield meaningful information.
