- Rye bran contains a high content not only of dietary fibre, but also of plant lignans and other bioactive compounds in the so-called dietary fibre complex. Blood concentrations of lignans such as enterolactone have been used as biomarkers of intake of lignan-rich plant food. At present,evidence from studies in human subjects does not warrant the conclusion that rye, whole grains orphyto-oestrogens protect against cancer. Some studies, however, have pointed in that direction,especially in relation to cancers of the upper digestive tract. A number of prospective epidemiological studies have clearly shown a protective effect of wholegrain cereals against myocardial infarctions. A corresponding protective effect against diabetes and ischaemic stroke(brain infarct) has also been demonstrated. It seems reasonable to assume that these protective effects are associated with one or more factors in the dietary fibre complex.

- Recent years have seen important advances in our understanding of the etiology, biology and genetics of kidney cancer. To summarize important achievements and identify prominent research questions that remain, a workshop was organized by IARC and the US NCI. A series of 'difficult questions' were formulated, which should be given future priority in the areas of population, genomic and clinical research.

- Introduction & Objectives: Antibiotic prophylaxis are administered as a routine to decrease the risk for septic complications following transrectal prostate biopsy. Fosfomycin administered 1 h or more prior to biopsy has equal or better infectious complication rates as compared to Ciprofloxacin in both prospective and retrospective studies from countries with high rates of antibiotic resistance. The aim of this study was to investigate if Fosfomycin administered immediately prior to prostate biopsy was as effective as Ciprofloxacin in Sweden, a country with low rates of antibiotic resistance.Materials & Methods: A randomized, controlled, open, multicenter, non-inferiority-study including men of all ages undergoing transrectal prostate biopsy was performed in the urology departments of three Swedish hospitals. The total number of patients were planned for 3448, divided into low and high infection risk groups. The low-risk group was randomized to either one dose of Fosfomycin 3g or Ciprofloxacin 750mg before biopsy. The high-risk group was randomized to either two doses of Fosfomycin 3g prior to biopsy and one more 24 h after biopsy or Ciprofloxacin 500mg once prior to biopsy and then twice daily for three days. The drugs were administered orally. All patients had a rectal swab for culture before and after biopsy. The endpoint was hospitalisation due to urinary tract infection within 14 days from biopsy, follow-up was performed with a phone interview.Results: The safety board prematurely interrupted the study after 42 included patients due to an unusual high number of hospitalisations. Four out of 20 patients (20%), three in the low-risk group and one in the high-risk group, had been hospitalised due to urosepsis in the Fosfomycin group. One further patient described fever symptoms but did not seek health care. No patient in the Ciprofloxacin group (n=21) described symptoms of infection from the urinary tract. One patient was lost to follow-up. A one-sided binomial test showed a p-value of <0.001. Two of the four hospitalised patients had a positive blood culture for Pseudomonas Aeruginosa and one had a positive rectal swab culture for Pseudomonas species both before and after biopsy.Conclusions: The study does not support the use of Fosfomycin administered immediately prior to prostate biopsy. The results may have been affected by the unexpected high number of Pseudomonas infections, a bacteria where Fosfomycin often lack effect. If Fosfomycin is to be used it should be with caution if Pseudomonas has been seen in earlier cultures

- Introduction: Radiotherapy is an established treatment option for prostate cancer (PCa), both as primary treatment and secondary treatment after radical prostatectomy (RP). Since 1998, detailed data on radiotherapy delivered to Swedish men with PCa (e.g. treatment modalities, absorbed doses, fractionation) have been collated within PCa data Base Sweden (PCBaSe). This study reports patterns of radical radiotherapy for PCa in Sweden over the past two decades. Materials and methods: All men with non-metastatic PCa (1998-2016) who received external beam radiotherapy (EBRT) or high or low dose-rate brachytherapy (HDR-BT/LDR-BT) were identified in PCBaSe. Analyses included: trends in radiation techniques, fractionation patterns and total doses over time; PCa-specific survival comparing treatment in 2007-2017 with 1998-2006; and regional variation in type of primary radiotherapy. Results: About 20,876 men underwent primary radiotherapy. The main treatment modalities include conventionally fractionated (2.0 Gy/fraction) EBRT (51%), EBRT with HDR-BT boost (27%) and hypofractionated (>2.4 Gy/fraction) EBRT (11%). EBRT with photon or proton boost and HDR-BT and LDR-BT monotherapies were each used minimally. Use of dose-escalated EBRT (>74 Gy) and moderate hypofractionation increased over time, while use of HDR-BT declined. Considerable regional variation in treatment modalities was apparent. Risk of PCa death following primary radiotherapy had declined for intermediate-risk (HR: 0.60; 95%CI 0.47-0.87) and high-risk PCa (HR: 0.72; 95%CI 0.61-0.86). Discussion: Increased use of dose escalation and hypofractionated EBRT has occurred in Sweden over the past two decades, reflecting current evidence and practice guidelines. Disease-specific outcomes have also improved. Data collected in PCBaSe provide an excellent resource for further research into RT use in PCa management.

- OBJECTIVE: To determine the role of vascular response in the castration-induced regression of benign and malignant human prostate tissue, as recent studies show that castration rapidly decreases blood flow and induces endothelial cell death, which may be important for subsequent epithelial cell death and involution of the glandular tissue of the prostate.MATERIALS AND METHODS: The expression of vascular endothelial growth factor (VEGF) and its receptors was analysed using the quantitative reverse transcriptase-polymerase chain reaction, in benign and tumour areas of core biopsies taken before, and approximately 1 week after castration therapy. The castration-induced VEGF response was related to therapy-induced changes in tumour cell apoptotic index and subsequent response in serum prostate-specific antigen (PSA). In another set of patients, serum VEGF was quantified by enzyme-linked immunosorbent assay before, and at 3--6 months after castration therapy.RESULTS: VEGF mRNA was down-regulated after castration in benign prostate tissue (P < or = 0.05), whereas in tumour tissue, VEGF levels were reduced in some of the patients but unchanged or increased in others. In most patients whose tumour tissue responded with VEGF reduction, there was a corresponding increase in tumour cell apoptosis. Serum VEGF levels were not significantly changed after castration. Almost all patients responded with a substantial reduction in serum PSA after castration.CONCLUSION: Castration reduces VEGF mRNA expression in benign prostate tissue and generally in those prostate tumours where castration also induces tumour cell apoptosis. This suggests that a therapy-induced down-regulation of VEGF could be important for tumour cell death.

- Scots pine (Pinus sylvestris L.) seedlings were grown under different conditions (three field locations, two seasons and two climate room regimes), and then analyzed for freezing tolerance of shoots and roots and for transcript abundance in apical buds based on a cDNA microarray containing about 1500 expressed sequence tags (ESTs) from buds of cold-treated Scots pine seedlings. In a climate room providing long daily photoperiods and high temperatures, seedlings did not develop freezing tolerance, whereas seedlings in a climate room set to provide declining temperatures and day lengths developed moderate freezing tolerance. Control seedlings grown outside under field conditions developed full freezing tolerance. Differences in physiological behavior of the different seedling groups, combined with molecular analysis, allowed identification of a large group of genes, expression of which changed during the development of freezing tolerance. Transcript abundance of several of these genes was highly correlated with freezing tolerance in seedlings differing in provenance, field location or age, making them excellent candidate marker genes for molecular tests for freezing tolerance.
