- Inflammation is a well-documented driver of cancer development and progression. However, little is known about its role in prostate carcinogenesis. Thus, we examined the association of C-reactive protein (CRP), haptoglobin, albumin and white blood cells (WBC) with prostate cancer (PCa) severity (defined by PCa risk category and clinicopathological characteristics) and progression (defined by PCa death). We selected 8,471 Swedish men with newly diagnosed PCa who had exposure measurements taken approximately 14 years prior to diagnosis. We calculated odds ratio (OR) and 95% confidence interval (CI) for the associations between the inflammatory markers and PCa severity using logistic regression, while Cox proportional hazard regression was used for the associations with overall and PCa death. Serum CRP levels were associated with increased odds of high risk and metastatic PCa, and high PSA levels (20 mu g/L) (OR: 1.29; 95% CI: 1.06-1.56, 1.32; 1.05-1.65 and 1.51; 1.26-1.81, respectively). Similarly, higher haptoglobin levels were associated with increased odds of metastatic PCa, high PSA level and possibly high grade PCa (1.38; 1.10-1.74, 1.50; 1.17-1.93 and 1.25; 1.00-1.56, respectively). Albumin was positively associated with Gleason 4+3 tumour (1.38; 1.02-1.86) and overall death (HRunit increase in log: 1.60; 95% CI: 1.11-2.30), but inversely associated with high risk PCa and high PSA levels (20 mu g/L) (0.71; 0.56-0.89 and 0.72; 0.5 9-0.90). WBC was associated with increased odds of T3-T4 PCa. Except for albumin, none of these markers were associated with PCa death or overall death. Systemic inflammation as early as 14 years prior to diagnosis may influence prostate cancer severity. What's new? High levels of C-reactive protein can presage a particularly malignant prostate cancer, new results show. Cancers certainly arise in the wake of chronic inflammation, but it's not known exactly how markers of inflammation initiate prostate cancer. Here, the authors show that systemic inflammation can worsen the severity of the cancer, even if it occurred long before the cancer's onset. High levels of CRP and haptoglobin, they found, were associated with prostate cancer with high PSA and metastasis. The question remains whether inflammation pushes cancer cells into a more malignant mode, or selects for the more dangerous cells early on.

- Introduction The first case of COVID-19 in Sweden was diagnosed in late January 2020, the first recommendations against the spread of the virus were released in mid-March, and the peak of the first wave of the pandemic was reached in March-June. The aim of this cross-sectional study was to assess the short-term effects of the first wave of the COVID-19 pandemic on prostate cancer (PCa) diagnosis, staging, and treatment. Materials and methods Data in the National Prostate Cancer Register (NPCR) of Sweden on newly diagnosed PCa cases and on the number of diagnostic and therapeutic procedures performed between 18 March 2020 and 2 June 2020 were compared with those in the corresponding time periods in 2017-2019, as reported until January 31 of the year after each study period. Results During the study period in 2020, 36% fewer PCa cases were registered in NPCR compared with the corresponding time period in previous years: 1458 cases in 2020 vs a mean of 2285 cases in 2017-2019. The decrease in new PCa registrations was more pronounced in men above age 75 years, down 51%, than in men aged 70-75, down 37%, and in men below age 70, down 28%. There was no decrease in the number of radical prostatectomies and number of radical radiotherapy courses increased by 32%. Conclusions During the peak of the first phase of the COVID-19 pandemic, the number of men diagnosed with PCa in Sweden decreased by one third compared with previous years, whereas there was no decrease in the number of curative treatments.

- Objectives: The aim of this study was to examine the use of abiraterone and enzalutamide, two oral novel antiandrogens (NOVAs), in men with prostate cancer (PCa) in Sweden. Materials and methods: This cross-sectional study investigated filled prescriptions for NOVAs recorded in the Swedish Prescribed Drug Register between July 2015 and April 2016. Associations between age, comorbidity, educational level, marital status and county of residence and filled prescriptions were analyzed in the National Prostate Cancer Register (NPCR) and other health population-based registers, using multivariable logistic regression. Results: Of 91,209 men, 1650 (2%) had at least one prescription filled for NOVAs, of whom 1350 (82%) had high-risk or metastatic PCa at diagnosis.. Of 1914 men with M1 disease and a high probability of castration-resistant prostate cancer (CRPC), 22% had a prescription for NOVAs at a median 3 years after the date of diagnosis. At multivariable logistic regression analysis,, the likelihood of NOVA use was lower in older men [age >80 vs <70 years: odds ratio (OR) 0.23, 95% confidence interval (CI) 0.15-0.35] and in men with lower educational level (high vs low education: OR 1.64, 95% CI 1.23-2.20). There was up to a five-fold difference in the use of NOVAs between county councils. Conclusions: Less than one-third of potentially eligible men with CRPC received NOVAs in 2015-2016. There were large differences in use according to age and region of residence, indicating that efforts are needed to improve equal access to novel cancer drugs.

- Adherence has not been studied in male oncology populations. The aim of this study on both the prescriber and user perspectives in prostate cancer treatment was to analyse real-life prescribing patterns of anti-androgens (AA), primarily bicalutamide, and factors influencing the patients' adherence to treatment. A nationwide clinical cohort of incident prostate cancer, PCBaSe, was linked to the Swedish Prescribed Drug Register. Men with a planned first line monotherapy AA treatment were identified; dosages and extent of off-label treatment were investigated. Cumulative incidence proportions for reasons for drug discontinuation were calculated. Factors potentially influencing adherence were explored using the medical possession ratio based on the individual prescribed daily dose. First line monotherapy AA was planned in 4.4 % of all incident cases and in 2.1 % of low risk disease cases. Among 1,406 men prescribed bicalutamide, 1,109 (79 %) received the approved daily dose of 150 mg. Discontinuation reasons differed with disease severity. Off-label, low-dose prescription associated with age above 75 years and disease categorised as low risk was noted in 297 men (21 %). Sixty percent of the men adhered well, i.e. to a parts per thousand yen80 %. Age above 75 years and less severe disease were both negatively associated with adherence. Patient age and tumour risk group influenced the prescriber's choice of dose, pointing to important issues for critical reflection. Possible over-treatment was noted in low risk disease. Interventions to increase adherence in older men and in men with less severe disease are worth considering after critically reviewing the appropriateness of the treatment indication, especially in the latter case.
