Abstract
Background
Definitive radiotherapy and vismodegib, an oral inhibitor of the hedgehog pathway, are both established treatment options for locally advanced basal cell carcinomas (BCC). Both have shown good results in local tumor control; however, the effects concerning advanced tumors are often not of a lasting nature and to date no systematic data about the combination of the two modalities are available.
Patients and methods
We retrospectively analyzed four patients who received vismodegib and radiotherapy in combination. Radiation doses varied between 50.4 Gy and 66.0 Gy. Three patients had recurrent BCC. One patient had locoregional lymph node involvement. Vismodegib was taken once a day (150 mg) during the entire time of irradiation and beyond upon instructions of the attending dermatologist.
Results
In three cases a persistent complete response was observed, in one case the tumor remained stable for approximately 6 months until further tumor progression was documented. The combined therapy was well tolerated in all cases. No exceptional side effects pointing at a drug–radiation interaction were observed.
Conclusion
The combination of vismodegib and radiation seems feasible and the initial results are promising. In our cohort, there was no increase in unexpected side effects. Further research is needed to evaluate the significance of this combined therapy.
Zusammenfassung
Hintergrund
Sowohl definitive Radiotherapie als auch Vismodegib, ein oraler Inhibitor der Hedgehog-Signalkaskade, sind etablierte Behandlungsoptionen für lokal fortgeschrittene Basalzellkarzinome (BCC). Beide Therapien zeigen für sich gute Ansprechraten, aber die lokale Tumorkontrolle ist oft nicht dauerhaft und bis heute existieren kaum Daten über eine Kombination der beiden Modalitäten.
Patienten und Methoden
Wir analysierten retrospektiv vier Patientenfälle nach simultaner Applikation von Vismodegib und Bestrahlung. Die Bestrahlungsdosis variierte zwischen 50,4 Gy und 66,0 Gy. Drei der Patienten hatten ein rezidiviertes BCC. Ein Patient hatte einen befallenen regionalen Lymphknoten. Vismodegib wurde einmal täglich (150 mg) über die gesamte Radiotherapie und nach deren Beendigung, je nach Empfehlung des betreuenden Dermatologen, eingenommen.
Ergebnisse
In drei Fällen konnte ein länger andauerndes Ansprechen beobachtet werden. In einem Fall verblieb der Tumor für 6 Monate stabil, bevor eine erneute Tumorprogression festgestellt werden konnte. Die kombinierte Therapie wurde in allen Fällen gut vertragen. Es konnten keine unerwarteten Nebenwirkungen beobachtet werden, die auf eine supraadditive Toxizität deuten könnten.
Schlussfolgerung
Die Kombination von Vismodegib und Radiotherapie erscheint möglich. Die ersten Ergebnisse sind vielversprechend. In unserer Kohorte konnte keine erhöhte Toxizität beobachtet werden. Künftige Studien sollten den Stellenwert dieser kombinierten Therapie untersuchen.
