| Abstract | Previous studies suggest that solar UV exposure in early life is predictive of cutaneous melanoma risk in adulthood, whereas the relation of BRAF mutation with sun exposure and disease prognosis has been less certain. We investigated the associations between BRAFV600E and NRASQ61R mutations and known risk factors, clinicopathologic characteristics and clinical outcomes of melanoma in a case series of primary invasive cutaneous melanoma from the Nurses’ Health Study (NHS).Somatic BRAFV600E and NRASQ61R mutations of 127 primary invasive melanomas from the NHS cohort were determined by pyrosequencing using formalin-fixed, paraffin-embedded block tissues. Logistic regression analyses were performed to detect the associations of mutations with melanoma risk factors, and Kaplan–Meier method was used to examine associations between mutations and survival.The odds ratios for harboring BRAFV600E mutations were 5.54 (95 % CI 1.19–25.8, p trend = 0.02) for women residing in states with UV index ≥ 7 versus those residing in states with UV index ≤5 at 30 years of age. Patients with BRAFV600E mutations tended to have shorter melanoma-specific survival when compared to patients with wild type at both loci (median survival time 110 vs. 159 months) (p = 0.03). No association was found between NRASQ61R mutation and melanoma risk factors or melanoma-specific survival.BRAFV600E mutations in primary cutaneous melanomas were associated with residence in locations with medium and high UV indices in mid-life. BRAFV600E mutation may be associated with an unfavorable prognosis among melanoma patients. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
