Zusammenfassung
Hintergrund
Die molekularpathologische Forschung bietet neue Chancen für das diagnostische und therapeutische Management von malignen Iristumoren. Neben der einfachen Immunhistologie und Polymerasekettenreaktionsanalyse können weitere Untersuchungsformen wie die multiplexe ligationsabhängige Sondenamplifikation, die Mikrosatellitenanalyse oder das Next-Generation-Sequencing verschiedene Mutationen im Tumorgenom detektieren.
Fragestellung
Es erfolgt die Darstellung aktueller molekularpathologischer Ansätze bei malignen Iristumoren.
Methoden
Dieser Beitrag bietet eine Übersicht über die aktuelle Literatur, basierend auf einer PubMed-Recherche und der klinischen Erfahrung bei Iristumoren.
Ergebnisse
Exemplarisch werden für das Irismelanom, das Irislymphom und die Iriskarzinommetastase diagnostische Besonderheiten und zielgerichtete Behandlungsoptionen dargestellt. Beim Irismelanom scheinen insbesondere Mutationen im GNA11- oder GNAQ-Gen (in ca. 85 % der Fälle) von Bedeutung zu sein. Ebenso empfiehlt es sich, den Monosomie-3-Status bei diesen Patienten zu untersuchen. Beim Irislymphom ist die molekularpathologische Aufarbeitung vor der exakten Diagnosestellung elementar. Ebenso ist die Detektion von Mutationen auf MYD88, BRAF, KLF2, ID3, TCF3, STAT3, RHo, TET2, IDH2, CXCR4, CD79B und DNMT3A hilfreich. Insbesondere der Nachweis des CD20-Antigens zieht eine therapeutische Relevanz nach sich, da diese Lymphome gut auf Rituximab, eine CD20-Antikörpertherapie, ansprechen. Auch bei Iriskarzinommetastasen sind Untersuchungen auf Mutationen hilfreich, da dann eine zielgerichtete Therapie möglich erscheint.
Schlussfolgerung
Die Molekularpathologie wird auch bei Iristumoren künftig unerlässlich werden, da sie den Schlüssel zu einer personalisierten Therapie darstellt.
Abstract
Background
Molecular pathological research offers new chances for the diagnostic and therapeutic management of malignant iris tumors. Besides immunohistological and polymerase chain reaction analyses further techniques, such as multiplex ligation-dependent probe amplification, microsatellite analyses and next-generation sequencing are able to detect various mutations in the tumor genome.
Objective
An up to date review of new molecular pathological strategies for malignant iris tumors was carried out.
Methods
This article provides a review of the recent literature based on a PubMed search and clinical experience with iris tumors.
Results
The diagnostic characteristics and targeted treatment options are presented, exemplified by iris melanoma and iris carcinoma metastases. In iris melanomas, mutations in the GNA11 and GNAQ genes (in approximately 85% of the cases) seem to be important. Furthermore, the monosomy-3 status should be investigated in these tumors. In iris lymphomas, molecular pathological analyses are essential for an exact diagnosis. Detection of mutations in MYD88, BRAF, KLF2, ID3, TCF3, STAT3, RHo, TET2, IDH2, CXCR4, CD79B and DNMT3A are helpful. In particular, the detection of the CD20 antigen is of therapeutic relevance because this lymphoma subgroup responds well to rituximab, a CD20 antibody treatment. In iris carcinoma metastases, investigations for mutations are helpful because then a targeted treatment seems to be possible.
Conclusion
Molecular pathological analyses will become essential in the future management of iris tumors because they play a key role towards a personalized treatment approach.
