- Background: Standardized care pathway (SCP) was introduced by the Swedish health authorities to eliminate unwanted delay in the diagnostics of cancer patients; for melanoma, SCP started in 2016. The aim of this study was to investigate the impact of SCP on reporting time for invasive melanomas.Materials and methods: Information on reporting time was collected on all samples handled according to the SCP and on all invasive melanomas diagnosed in 2016–2018 at the Department of Clinical Pathology, Akademiska University Hospital, Uppsala, Sweden.Results: During the study period, 205 samples were handled according to the SCP, resulting in 53 cases (26%) diagnosed with invasive melanomas. A total of 301 invasive melanomas from 286 patients were diagnosed during the study period; 67 (22%) were submitted as SCP, 36 (12%) as a general priority case, and 198 (66%) as non-priority. The reporting time for the SCP cases was 8 days, for general priority cases 6 days, and for non-priority cases it was 24 days. The reporting time increased from 18 to 31 days for the non-priority cases and from 15 to 25 days for all cases with invasive melanomas during the study period.Conclusion: This study demonstrates prolonged reporting times for invasive melanomas since the implementation of SCP. This is probably caused by the crowd-out effect of the SCP samples, limited personnel resources, and inaccuracy of the clinical diagnosis. SCP might therefore be a suboptimal method to shorten reporting times for invasive melanomas.

- Background: The incidence of invasive cutaneous melanoma (CM) is increasing in Sweden. The aim was to present age-and sex-specific trends of the age-standardised incidence and the average annual percentage change (AAPC) for in situ and invasive CM. Methods: Joinpoint regression models were used to analyse data from the Swedish Cancer Register and the Swedish Melanoma Registry 1997–2018 (N = 35,350 in situ CM; 59,932 CM). Results: The AAPC of CM for women was 4.5 (4.1–5.0; p < 0.001) for the period 1997–2018. For men, the APCC was 4.2 (3.0–5.4; p < 0.001), with a significantly higher annual percentage change (APC) for the period 2000–2018 (5.0; 4.6–5.4; p < 0.001) compared to 1997–1999. An increasing annual incidence of CM ≤ 0.6 mm and 0.7 mm Breslow tumour thickness was found for men with a significant incidence shift for the period 2006–2015, respectively. Similarly for women, with a significantly higher APC for CM ≤ 0.6 mm from 2005. The incidence of intermediate thick CM (2.1–4.0 mm) has not increased since 2011. The incidence of CM > 4.0 mm has been increasing among both sexes, with a significantly lower APC among women from 2005. Conclusions: The incidence of in situ and low-risk CM ≤ 1.0 mm in tumour thickness has been rising among both sexes since the 2000s.

- Propionibacterium acnes (P. acnes) and Propionibacterium granulosum (P. granulosum) are common skin colonizers that are implicated as possible contributing factors in acne vulgaris development. We have established direct visualization tools for the simultaneous detection of these closely related species with immunofluorescence assay and fluorescence in situ hybridization (FISH). As proof of principle, we were able to distinguish P. acnes and P. granulosum bacteria in multi-species populations in vitro as well as in a mock skin infection model upon labelling with 16S rRNA probes in combinatorial FISH as well as with antibodies. Furthermore, we report the co-localization of P. acnes and P. granulosum in the stratum corneum and hair follicles from patients with acne vulgaris as well as in healthy individuals. Further studies on the spatial distribution of these bacteria in skin structures in various skin disorders are needed.

- BACKGROUND: The melanoma-specific survival (MSS) is heterogenous between stages and is highly dependent on the T stage for primary localized disease. New systemic therapies for metastatic cutaneous melanoma (CM) have been introduced since 2012 in Sweden.OBJECTIVES: To analyse the incidence and MSS time trends between 1990 and 2020 in Sweden.METHODS: Nationwide, population-based, and prospectively collected clinico-pathological data on invasive CM from the Swedish Melanoma Registry (SweMR) were analysed for survival trends between 1990 and 2020 by using Kaplan-Meier curves and Cox Proportional Hazard ratios.RESULTS: In total, 77 036 primary invasive CM were diagnosed in 70 511 patients in Sweden between 1990 and 2020. The 5-year MSS was 88.9% (88.3-89.4) 1990-2000, 89.2% 2001-2010, and 93.0% (92.7-93.9) 2011-2020. The odds ratios for being diagnosed with nodular melanomas (vs. superficial spreading melanoma) was significantly reduced by 20% (2001-2010) and by 46% (2011-2020 vs. 1990-2000). Overall, the MSS improved over both diagnostic periods (2001-2010 and 2011-2020) vs the reference period 1990-2000 among men and women, respectively, (HRmen, 2001-2010: 0.89, 95% CI 0.82-0.96; HRmen, 2011-2020: 0.62, 95% CI 0.56-0.67. HRwomen, 2001-2010: 0.82, 95% CI 0.74-0.91; HRwomen, 2011-2020: 0.62, 95% CI 0.56-0.70). The risk of CM-death was significantly lower in all age groups for both men and women in the most recent diagnostic period (2011-2020 vs. 1990-2000).CONCLUSIONS: The results are emphasizing the improved MSS among both men and women in Sweden. The MSS improvements, specifically for the period 2011-2020, may be correlated to the introduction of new systemic therapies and are here shown for the first time in detail for Sweden.
