Malignes Melanom S3-Leitlinie “Diagnostik, Therapie und Nachsorge des Melanoms”

Implementation of a dermatoscopy curriculum during residency at Augsburg University Hospital in Germany

BACKGROUND AND OBJECTIVES

To date, there is no structured program for dermatoscopy training during residency in Germany. Whether and how much dermatoscopy training is acquired is left to the initiative of each resident, although dermatoscopy is one of the core competencies of dermatological training and daily practice. The aim of the study was to establish a structured dermatoscopy curriculum during residency at the University Hospital Augsburg.

PATIENTS AND METHODS

An online platform with dermatoscopy modules was created, accessible regardless of time and place. Practical skills were acquired under the personal guidance of a dermatoscopy expert. Participants were tested on their level of knowledge before and after completing the modules. Test scores on management decisions and correct dermatoscopic diagnosis were analyzed.

RESULTS

Results of 28 participants showed improvements in management decisions from pre- to posttest (74.0% vs. 89.4%) and in dermatoscopic accuracy (65.0% vs. 85.6%). Pre- vs. posttest differences in test score (7.05/10 vs. 8.94/10 points) and correct diagnosis were significant (p < 0.001).

CONCLUSIONS

The dermatoscopy curriculum increases the number of correct management decisions and dermatoscopy diagnoses. This will result in more skin cancers being detected, and fewer benign lesions being excised. The curriculum can be offered to other dermatology training centers and medical professionals.

Implementierung eines Dermatoskopie-Curriculums in der Facharztausbildung am Universitätsklinikum Augsburg

Hintergrund und Ziele

Bislang gibt es in Deutschland kein strukturiertes Programm für die Dermatoskopieausbildung während der Facharztausbildung. Es bleibt der Initiative des einzelnen Assistenzarztes überlassen, ob und in welchem Umfang er sich in der Dermatoskopie weiterbildet, obwohl die Dermatoskopie zu den Kernkompetenzen der dermatologischen Ausbildung und der täglichen Praxis gehört. Ziel der Studie war die Etablierung eines strukturierten Dermatoskopie‐Curriculums während der dermatologischen Facharztausbildung am Universitätsklinikum Augsburg.

Patienten und Methodik

Es wurde eine Online‐Plattform mit Dermatoskopie‐Modulen geschaffen, auf die von überall und jederzeit zugegriffen werden kann. Praktische Fertigkeiten wurden unter individueller Anleitung eines Dermatoskopie‐Experten erworben. Die Teilnehmer wurden vor und nach Abschluss der Module auf ihren Wissensstand getestet. Die Testergebnisse zum therapeutischen Management und zur korrekten dermatoskopischen Diagnose wurden analysiert.

Ergebnisse

Die Ergebnisse der 28 Teilnehmer verbesserten sich vom Eingangs‐ zum Abschlusstest bei der Managemententscheidung (74,0% vs. 89,4%) und bei der dermatoskopischen Genauigkeit (65,0% vs. 85,6%). Die Unterschiede zwischen Eingangs‐ und Abschlusstest bei der Gesamtpunktzahl (7,05/10 vs. 8,94/10 Punkte) und bei der richtigen Diagnose waren signifikant (p < 0,001).

Schlussfolgerungen

Das Dermatoskopie‐Curriculum verbessert die Managemententscheidungen und die dermatoskopische Diagnostik der Teilnehmer. Das wird dazu führen, dass mehr Hautkrebsfälle erkannt werden und weniger gutartige Läsionen reseziert werden müssen. Das Curriculum kann anderen dermatologischen Ausbildungszentren und Gesundheitsberufen angeboten werden.

Skin Cancer Screening and Medical Treatment Intensity in Patients with Malignant Melanoma and Non-Melanocytic Skin Cancer

BACKGROUND

This cohort study concerns the effect of skin cancer screening (SCS) on medical treatment intensity in patients with skin cancer.

METHODS

Routine data from persons aged 35 to 99 who were insured by the AOK health insurance company were used to identify persons who received a diagnosis of malignant melanoma or a non-melanocytic skin cancer in 2014 or 2015, either through skin cancer screening or without screening. These persons were included in cohort studies. The routine data contained no information on tumor stages or grading. Tumor-associated rates of hospital admission, contact with physicians in outpatient practice, and intensity of surgical treatment were determined; rate ratios (RR) and their 95% confidence intervals (CI) were estimated.

RESULTS

The cohort studies included 13 633 patients with melanoma (6480 with SCS and 7153 without) and 118 168 patients with non-melanocytic skin cancer (43 308 with screening and 74 860 without). Patients whose melanomas had been detected by screening had a lower medical treatment intensity than unscreened patients (intensity of tumor-associated surgical treatment (RR = 0.79, 95% CI [0.74; 0.85]), hospital contact rate (RR = 0.44, 95% CI: [0.38; 0.50]), contact with physicians in outpatient practice (RR = 0.79, 95% CI: [0.73; 0.85]). Among patients with non-melanocytic skin cancer, the screened patients displayed a lower hospital contact rate (RR = 0.52, 95% CI: [0.49; 0.56]), a higher contact rate in the outpatient sector (RR = 1.11, 95% CI: [1.08; 1.13]), and no difference in surgical treatment intensity (RR = 0.98, 95% CI: [0.96; 1.00]).

CONCLUSION

SCS is associated with lower medical treatment intensity in the first 12 months after diagnosis in patients with melanoma. Among patients with non-melanocytic skin cancer, those who had been screened had lower hospital contact rates, but there was no observed lowering of other rates reflecting treatment intensity.

Prioritization and comprehensive analysis of genes associated with melanoma

Melanoma is a malignant tumor derived from melanocytes, which occurs mostly in the skin. A major challenge in cancer research is the biological interpretation of the complexity of cancer somatic mutation profiles. The aim of the present study was to obtain a comprehensive understanding of the formation and development of melanoma and to identify its associated genes. In the present study, a pipeline was proposed for investigating key genes associated with melanoma based on the Online Mendelian Inheritance in Man and Search Tool for the Retrieval of Interacting Genes/Proteins databases through a random walk model. Additionally, functional enrichment analysis was performed for key genes associated with melanoma. This identified a total of 17 biological processes and 30 pathways which may be associated with melanoma. In addition, melanoma-specific network analysis followed by Kaplan-Meier analysis along with log-rank tests identified tyrosinase, hedgehog acyltransferase, BRCA1-associated protein 1 and melanocyte inducing transcription factor as potential therapeutic targets for melanoma. In conclusion, the present study increased the knowledge of melanoma progression and may be helpful for improving its prognosis.
