A country-wide teledermatoscopy service in Estonia shows results comparable to those in experimental settings in management plan development and diagnostic accuracy: A retrospective database study.

Background: Teledermatoscopy accuracy has been examined in experimental settings and is recommended for primary care despite lacking real-world implementation evidence. A teledermatoscopy service has been provided in Estonia since 2013, where lesions are evaluated based on the patient's or general practitioner's suggestion.

Objective: The management plan and diagnostic accuracy of a real-world store-and-forward teledermatoscopy service for melanoma diagnosis were evaluated.

2-cm versus 4-cm surgical excision margins for primary cutaneous melanoma thicker than 2 mm: a randomised, multicentre trial.

Background: Optimum surgical resection margins for patients with clinical stage IIA-C cutaneous melanoma thicker than 2 mm are controversial. The aim of the study was to test whether survival was different for a wide local excision margin of 2 cm compared with a 4-cm excision margin.

Methods: We undertook a randomised controlled trial in nine European centres.

Prior immunisation of patients with malignant melanoma with vaccinia or BCG is associated with better survival. An European Organization for Research and Treatment of Cancer cohort study on 542 patients.

There is increasing evidence that infections and vaccinations play an important role in the normal maturation of the immune system. It was therefore of interest to determine whether these immune events also affect the prognosis of melanoma patients. A cohort study of 542 melanoma patients in six European countries and Israel was conducted.

Impact of vaccinations and infectious diseases on the risk of melanoma--evaluation of an EORTC case-control study.

A significant correlation between a reduced risk of melanoma and BCG and vaccinia vaccination in early childhood or infectious diseases later in life has already been reported from the FEBrile Infections and Melanoma (FEBIM) multicentre case-control study. This correlation is further evaluated in this study based on 603 incident cases of malignant melanoma and 627 population controls in six European countries and Israel by means of a joint analysis of the influence of vaccinations and infectious diseases. In addition, the previously unconsidered impact of influenza vaccinations is evaluated for the whole study population.

Inverse association between melanoma and previous vaccinations against tuberculosis and smallpox: results of the FEBIM study.

Various forms of immunotherapy utilizing bacille Calmette-Guérin vaccine or vaccinia vaccine have been evaluated in clinical trials on melanoma patients. The effect of the "natural" application of these vaccinations, administered to provide protection against tuberculosis and smallpox, has, however, never been studied in epidemiologic investigations on risk factors for melanoma. In a case-control study comprising 11 institutions in seven countries we recruited 603 incident melanoma cases and 627 population controls frequency matched to the cases with respect to sex, age, and ethnic origin within each center to assess this relationship to obtain insights into the prevention of melanoma.
