Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study was reviewed as an RO1 Grant from the National Cancer Institute in 1995. Subject enrollment, which included clinical evaluation, epidemiologic questionnaires, and skin and blood sample collection, was completed in 1999 on approximately 180 melanoma cases and 180 controls identified in Italy. The study protocol and consent form both included the measurement of genetic and biochemical factors and DNA repair capacity. DNA repair proficiency was measured in lymphocytes by the host cell reactivation assay, and sun exposure was evaluated by means of a detailed questionaire. Photographs of the back of the subjects were taken to allow nevi count. Minimal erythemal dosage was measured in all subjects to estimate skin sun sensitivity 24 hours after skin's UV-irradiation. Skin color was ascertained on the inner side of the forearm by means of a Minolta chromometer.
The aim of this protocol is to continue analysis of the biological samples already collected, as originally outlined in the study protocol. In particular, we plan to measure polymorphisms in genes that may lead to susceptibility to melanoma. Initially we will concentrate on variation in genes involved in repairing damaged DNA, but plan to look at a broad group of candidate susceptibility genes.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The aim of this protocol was to continue the analysis of the biological samples and data already collected, as originally outlined in the study protocol. However, the original sample size was small and precluded specific analyses of gene-environment interaction crucial for the understanding of the etiology of melanoma. We have identified other collaborators willing to share their data and sample with us to increase the power for statistical analyses. We obtained approval (amendments to 02-C-N035 approved in November 2006, September 2008, December 2010, and June 2011) to use the DNA samples and data collected in four studies conducted by investigators at the University of L'Aquila, Italy, University of Genoa, Italy, Istituto Valenciano de Oncologia, Valencia, Spain, and the New York University School of Medicine, respectively. We have obtained approval with stipulations in August 2014 to also include samples and data collected from the Papa Giovanni XXII Hospital in Bergamo, Italy and the University of Athens, Greece. We are now responding to the stipulations and asking to further include samples from the University of Padua and the Hospital Clinic of Barcelona within the same study.
We are currently analyzing genes in several pathways, including pigmentation, DNA repair, immune-related functions and those involved in the transition from nevi to melanoma (genes in the cell cycle, telomere, signaling pathways, etc). With the additional samples we plan to conduct a GWAS analysis of melanoma in Mediterranean countries and a molecular analysis of melanoma tissue lesions for an improved classification of the disease and its association with melanoma progression.
