We recently reported an increased risk of uveal melanoma among mobile phone users. Here, we present the results of a case-control study that assessed the association between mobile phone use and risk of uveal melanoma. We recruited 459 uveal melanoma case patients at the University of Duisburg-Essen and matched 455 case patients with 827 population control subjects, 133 with 180 ophthalmologist control subjects, and 187 with 187 sibling control subjects. We used a questionnaire to assess mobile phone use and estimated odds ratios (ORs) and 95% confidence intervals (95% CIs) of risk for uveal melanoma using conditional logistic regression. Risk of uveal melanoma was not associated with regular mobile phone use (OR = 0.7, 95% CI = 0.5 to 1.0 vs population control subjects; OR = 1.1, 95% CI = 0.6 to 2.3 vs ophthalmologist control subjects; and OR = 1.2, 95% CI = 0.5 to 2.6 vs sibling control subjects), and we observed no trend for cumulative measures of exposure. We did not corroborate our previous results that showed an increased risk of uveal melanoma among regular mobile phone users.

    • "Low response rates make difficult ascertaining a population-based control group representative of the general population. Since no perfect control group was found, we choose two distinct control groups to test our hypotheses on populations presenting different aspects of the general population, as made by Stang et al. [49]. Controls from Group A and Group B present both advantages and weaknesses (see Table 2). "

    ABSTRACT: Background The incidence of testicular germ cell tumors (TGCT), the most common cancer in men aged 15 to 45 years, has doubled over the last 30 years in developed countries. Reasons remain unclear but a role of environmental factors, especially during critical periods of development, is strongly suspected. Reliable data on environmental exposure during this critical time period are sparse. Little is known on whether it could be a combined effect of early and later-life exposures. Methods/Design Our research aims to study the association between TGCT risk and pesticide exposures (domestic, occupational and environmental) during critical time periods of development and combined early and later-life exposures. The study design, developed during a 2-year pilot study, is a multicenter case–control study of 500 cases (ascertained through histology) and 1000 fertile/fecund controls recruited through 21 French ‘Centres d’Etude et de Conservation des Œufs et de Sperme humain’ (CECOS). Trained professional interviewers interview the subjects and their mothers by phone. Using a geographic information system developed and tested for application in this study design, environmental pesticides exposure assessment is based on life-time residential history. Occupational pesticides exposures are assessed by an industrial hygienist based on parents’ occupations and tasks. Exposures during the prenatal period, early childhood and puberty are focused. A blood sample is collected from each participant to assess genetic polymorphisms known to be associated with TGCT risk, as well as to explore gene-environment interactions. Discussion The results of our study will contribute to better understanding the causes of TGCT and the rapid increase of its incidence. We explore the effect of combined early and later-life pesticides exposure from multiple sources, as well as potential gene-environment interactions that have until now been rarely studied for TGCT. Our design allows future pooled studies and the bio-bank allows additional genetic or toxicological analyses.

    ABSTRACT: Ocular melanoma is the second most common type of melanoma after cutaneous and the most common primary intraocular malignant tumor in adults. Large majority of ocular melanomas originate from uvea, while conjunctival melanomas are far less frequent. Incidence of uveal melanoma has remained stable over last three decades. Diagnosis is in most cases established by clinical examination with great accuracy. Local treatment of uveal melanoma has improved, with increased use of conservative methods and preservation of the eye, but survival rates have remained unchanged. Recent advances in cytogenetics and genetics enhanced prognostication and enabled to determine tumors with high metastatic potential. However, due to lack of effective systemic therapy, prognosis of patients with metastasis remains poor and metastatic disease remains the leading cause of death among patients with uveal melanoma. Conjunctival melanoma is rare, but its incidence is increasing. It mostly occurs among white adults. In majority of cases it originates from preceding primary acquired melanosis. Current standard treatment for conjunctival melanoma is wide local excision with adjuvant therapy, including brachytherapy, cryotherapy and topical application of chemotherapeutic agent. Rarity of this tumor limits conduction of controlled trials to define the best treatment modality. As well as for uveal melanoma, prognosis of patients with metastasis is poor because there is no effective systemic therapy. Better understanding of underlying genetic and molecular abnormalities implicated in development and progression of ocular melanomas provides a great opportunity for development of targeted therapy, which will hopefully improve prognosis of patients with metastatic disease.

The risk of uveal melanoma has been investigated by a German study group in two studies, of which the first reported an increased risk (Stang et al. 2001) but the second did not detect such an association (Stang et al. 2009).
