| Abstract | OBJECTIVES: Epidermal growth factor (EGF) stimulates cell proliferation by binding to its receptor (epidermal growth factor receptor), and the overexpression of this receptor is associated with poorer prognosis. The EGF gene presents a polymorphism at position 61 (A/G), associated with higher EGF production. We examined the association between this polymorphism and cervical cancer through a case-control study. METHODS: This study used the PCR-restriction fragment length polymorphism method on a sample of 384 women with cervical lesions and 500 controls of white ethnicity. RESULTS: In cases of cervical cancer, we found an increased risk of progression to advanced disease (The International Federation of Gynecology and Obstetrics stage IIb/IV) (odds ratios=2.05; 95% confidence intervals=1.11 to 3.79; P=0.021), and this risk was particularly evident in G carriers for younger women (odds ratios=2.96; 95% confidence intervals=1.41-6.20, P=0.003). CONCLUSIONS: We hypothesize the onset of an advanced disease-driven selective pressure due to the effect of oncogenic human papillomavirus types in a favorable genetic background observed in G carrier women. These results suggest that EGF functional polymorphism may influence cervical cancer prognosis through an EGF/epidermal growth factor receptor pathway. |

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.
