The long-term outcome of TET patients is related to tumor stage, WHO histotype, completeness of surgical removal, and type of treatment. Prospective trials are warranted to formally address the efficacy of adjuvant therapy in the treatment of localized and advanced malignant TETs.

In summary, there is consistent epidemiological evidence for a positive association between occupational UV light exposure and SCC risk.

Our data suggest it may be possible to identify patients who require intensified preventive measures due to their relatively higher risk for severe anaphylaxis by considering endogenous and exogenous factors.

SummaryBasal cell carcinoma (BCC) is the most common malignant tumor among fair‐skinned individuals, and its incidence had been steadily rising in the past decades. In order to maintain the highest quality of patient care possible, the German S2k guidelines were updated following a systematic literature search and with the participation of all professional societies and associations involved in the management of the disease. Part 2 addresses issues such as proper risk stratification, the various therapeutic approaches, and prevention as well as follow‐up of patients with basal cell carcinoma.

Published epidemiological literature indicates that outdoor workers are at significantly increased risk for BCC. This finding is highly relevant for health policy to stimulate the implementation of effective prevention strategies.
