AbstractFor the management of basal cell carcinoma, the primary performance of a risk stratification, which is decisive for the further diagnostic and therapeutic steps, is becoming increasingly important.Various non-invasive methods are available to confirm the clinical diagnosis. Histological confirmation of the diagnosis is recommended in unclear cases. In poorly displaced lesions, preoperative cross-sectional imaging of the tumor area should be performed to exclude osseous infiltration.The gold standard in treatment remains surgery, which should be performed by means of micrographically controlled surgery if possible. In addition, there are other therapeutic methods such as radiotherapy or a number of topical therapy options (photodynamic therapy, cryotherapy or application of 5-fluorouracil or imiquimod), which can be used in certain cases. Also for advanced or metastatic basal cell carcinoma, effective drugs are available in the form of the hedgehog inhibitors, for which there is now several years of application experience with regard to efficacy and handling of adverse events. With the PD-1 inhibitor cemiplimab, a further therapeutic option for non-operable or metastatic tumors has been available since June 2021.The most important preventive measure is consistent textile or chemical UV protection in already affected individuals. In addition, nicotinamide and celecoxib can be used orally for prevention. For follow-up, the current S2k guideline recommends regular self-monitoring and standardized medical check-ups.Thieme.
