Introduction: In Germany, incidence rates of basal cell (BCC) and squamous cell carcinoma (SCC) rose significantly from 1998 to 2010. Ultraviolet (UV) light exposure, immunosuppressants and drugs with photosensitising potential are known to increase the risk to develop BCC and SCC. The aim of our study was to analyse the adverse drug reaction (ADR) reports from Germany referring to BCC and SCC and to compare them to BCC and SCC occurring in the general population. Methods: We analysed all validated spontaneous ADR reports referring to BCC (n = 191) and SCC (n = 75) from Germany contained in the European ADR database EudraVigilance prior to 6 March 2019. These reports were compared to 1,267,210 BCC and 476,903 SCC cases from the German Centre for Cancer Registry Data recorded from 2006 to 2018. Results: The number of BCC and SCC reports as well as the BCC and SCC incidences in the registry increased in the analysed time period. Patients with drug-associated BCC (60 years) and SCC (64 years) were younger than patients with BCC (72 years) and SCC (76 years) in the registry. In 57.1 and 60.0% of BCC and SCC reports immunosuppressants were reported as suspected. The reported suspected drug was assumed to possess a photosensitising potential in 41.9 and 44.0% of BCC and SCC reports. Conclusions: In Germany, drug-associated BCC and SCC occurred at a younger age than in the general population. The results underline the necessity for skin cancer screening of patients treated with immunosuppressants or with drugs with photosensitising potential. [ABSTRACT FROM AUTHOR]

Most patients with advanced basal cell carcinomas (BCCs) may not benefit sufficiently from standard treatment comprising surgery and radiation. Vismodegib, an oral selective hedgehog pathway inhibitor, is approved for treatment of patients with locally advanced BCC inappropriate for surgery or radiotherapy, or for patients with symptomatic metastatic BCC. In order to enhance understanding of the effectiveness, safety and utilization of vismodegib in clinical practice in Germany, a non-interventional study, JONAS, was conducted. A total of 53 patients with locally advanced BCC who initiated treatment with vismodegib between 2016 and 2018 were included in the study, which was embedded in the German ADOReg skin cancer registry. Duration of response, the primary endpoint, was 12.4 months, progression-free survival 32.2 months and overall response rate 77.4%. Most adverse events were mild to moderate. Overall, results confirmed previous findings, demonstrating favourable responses and manageable safety of vismodegib in patients with locally advanced BCC in clinical practice.

Background Renal transplant recipients have an increased cancer risk. The mammalian target of rapamycin inhibitor sirolimus (SRL) has immunosuppressive and antitumour activities but knowledge about its use in recipients with cancer is limited. Methods We retrospectively analysed 726 renal allograft recipients converted to SRL from 10 German transplant centres. Patient and graft survival were analysed depending on malignancy status prior to conversion and tumour entity. Results Malignancy before conversion to SRL was reported in 230 patients, with 137 patients having skin cancers and 101 having solid cancers. Cancer occurred 4.6 ± 9.4 (median 3.0) years after transplantation. Basal cell carcinoma, squamous cell carcinoma and Bowen's disease were the most prevalent skin cancers, while carcinomas of the kidney, colon and breast were the most prevalent solid cancers before conversion. Patients with prior malignancy were older and had better renal function at conversion compared with patients without a history of cancer. After conversion to SRL, cancer incidence rates (IRs) of all tumours were lower compared with rates before conversion. Cancer IRs after conversion were higher in patients with malignancy before conversion compared with those without. Patient survival was worse in patients with solid cancers compared with patients with skin cancers or without malignancies. Biopsy-proven acute rejections in the first year after conversion were less frequent in patients with malignancy compared with those without. Graft survival and renal function in all cancer types were better than in patients converted to SRL without cancers. Conclusions Conversion to SRL in patients with a history of cancer is safe regarding renal function and graft survival, while patient survival is largely dependent on tumour entity.

Background Dermatologists have repeatedly criticized that the public health importance of nonmelanoma skin cancers is not appropriately reflected by the patient-based cancer incidence rates of population-based cancer registries. The aims of this study were to estimate the patient incidence rates of squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and skin melanoma, and to study the effect of multiple primary skin tumors on the incidence rates. Methods We used a network of physicians covering a population of about 75,000 individuals to register all newly diagnosed invasive skin cancers (996 diagnoses in 796 patients), including BCC, SCC, and skin melanoma, from July 1998 to June 2003. We calculated age-standardized (world standard population) incidence rates (cases per 100,000 person-years) for the first diagnoses (called “patient incidence”) and for any diagnoses of BCC, SCC, and skin melanoma (called “case incidence”). Results The patient incidence rates of BCC were 63.6 in men and 54.0 in women, and the case incidence rates of BCC were 82.7 and 71.1, respectively. The patient incidence rates of SCC were 17.4 in men and 9.7 in women, and the case incidence rates were 20.4 and 10.2, respectively. The patient and case incidence rates of skin melanoma were about the same at 13.6 in men and 18.5 in women. Twenty-five per cent of the BCC patients and 14% of the SCC patients suffered from more than one BCC and SCC, respectively, during the 5-year period. Conclusions Patient incidence rates of BCC and SCC substantially underestimate the burden of nonmelanoma skin cancer in the population. [ABSTRACT FROM AUTHOR]

Population-based figures on skin cancer are essential for a realistic assessment of the personal disease burden, prevention modes and the need for caring. The Robert Koch Institute in Germany estimates the incidence of melanoma skin cancer as seven cases in 100 000 persons (age-standardized by the European standard rate). Population-based studies presumably show higher incidence rates of 10–16 cases in 100 000 persons. Few data exist for non-melanoma skin cancer (NMSC) as this is not systematically registered in Germany. To present the first population-based results from the Schleswig-Holstein (Germany) Cancer Registry on incidence, stage distribution, clinical types and localization of skin cancer and to compare the results with other studies. The Cancer Registry of the Bundesland Schleswig-Holstein with 3500 registering institutions, 100 of which are dermatological institutions, investigates all notifiable incident cancer cases according to international standards. From the recorded data all melanoma and NMSC cases were identified and evaluated. Between 1998 and 2001, 1784 malignant melanoma (MM) and 12 956 NMSC cases underwent diagnostic and analytical evaluation. For MM, age-standardized incidence rates were 12·3 and 14·8 in 100 000 men and women, respectively, and the mean age of men was greater than that of women (56·6 vs. 54·9 years, P < 0·05). Superficial spreading melanoma was the most frequent clinical type (39·1%). The tumours were predominantly located on the trunk in men (46·8%) in contrast to leg and hip in women (39·5%). For NMSC, the age-standardized incidence rates were 100·2 and 72·6 in 100 000 men and women, respectively. More than 80% of all tumours were basal cell carcinoma. The first population-based data from Schleswig-Holstein on the characteristics (age, sex, histological subtypes, localization and stage) of skin tumours agree well with the existing literature and may thus be regarded as representative. However, markedly higher incidences for MM and NMSC in the north of Germany compared with other parts of the country were observed. As the incidence rates from the north of Germany fit well into the European geographical pattern, we assume no regional increase. Therefore, the official German estimates on cutaneous tumours may largely depend on regional factors and may not be regarded as representative for all regions in Germany. [ABSTRACT FROM AUTHOR]

We analysed incidence data of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin from the Cancer Registry Saarland, Germany. During 1995-1999, the age-standardised incidence rates (world standard population) of BCC and SCC were 43.7 and 11.2 per 100?000 among men and 31.7 and 4.4 per 100?000 among women.British Journal of Cancer (2003) 89, 1205-1208. doi:10.1038/sj.bjc.6601294 www.bjcancer.com [ABSTRACT FROM AUTHOR]
