Survival of Patients with Cutaneous Squamous Cell Carcinoma: Results of a Prospective Cohort Study
Cutaneous squamous cell carcinoma (cSCC) is an increasing health burden in white populations. We prospectively assessed risk factors for tumor-specific and overall survival in 1,434 patients who underwent surgery for cSCC between January 24, 2005, and May 29, 2015. A total of 2,149 invasive cSCCs were analyzed. Univariate and multivariate survival analyses included tumor thickness, horizontal size, body site, histological differentiation, desmoplastic growth, history of multiple cSCCs, and immunosuppression.Serial or Parallel Metastasis of Cutaneous Melanoma? A Study of the German Central Malignant Melanoma Registry
For more than a century the Halstedian hypothesis of contiguous metastasis from the primary tumor through the lymphatics to distant sites shaped lymph node surgery for melanoma. We challenge this dogma of serial metastatic dissemination. A single-center series of 2,299 patients with cutaneous metastatic melanoma was investigated to analyze overall survival and distant metastasis-free survival of stage IV patients with or without primary lymphatic metastasis. Results were then compared with those of 2,134 patients from three independent centers of the German Central Malignant Melanoma Registry.Incidence, Mortality, and Trends of Nonmelanoma Skin Cancer in Germany
Increasing incidence rates (IRs) of nonmelanoma skin cancer (NMSC) in white populations have been described worldwide. Cancer registry data from the Saarland and Schleswig-Holstein federal states were used to analyze incidence and mortality trends in Germany. Age-standardized rates were compared with crude rates to assess disease burden. Joinpoint regression models were used to estimate annual percentage changes and 95% confidence intervals, allowing us to assess temporal trends between 1970 and 2012.
