Abstract:Background: Ovarian cancer is the leading cause of cancer related death amongst women in India. Identification of histological types helps to predict tumor behaviour and further appropriate management. Aims and objectives is to study the histopathological parameters of ovarian tumor.Methods: This retrospective study was done on patients who presented ovarian mass and subsequently underwent surgery in a Regional Cancer Centre, Odisha, over a period of three years from January 2016 to December 2018.

“…Even with vast advancements in the treatment of ovarian carcinoma, it still remains the second most common cause of death among gynecological malignancies in the world. Due to anatomical position, complicated histopathology, nonspecific symptoms, and late presentations, ovarian neoplasms are diagnosed usually in late stages [ 3 ]. Despite intensive research in this field, effective screening tools are still not available to identify the disease at early stages.…”
Background: Matrix metalloproteinase-7 (MMP7) plays multiple roles in different stages of tumor development. Elevated MMP7 activity has been reported in ovarian cancer. Single nucleotide polymorphism (SNP) of promoter sites of the MMP7 gene has been shown to cause alteration in gene expression, hence resulting in changes in susceptibility to various diseases and tumor development.
Methods: The current study evaluated the association of epithelial ovarian cancer risk with MMP7 promoter site -181A>G polymorphism in the population of eastern India. The present case-control study included 64 histopathologically confirmed cases of epithelial ovarian cancer and 100 control subjects. The MMP7 -181A/G polymorphism was identified using polymerase chain reaction-restriction fragment length polymorphism. The association between genotypes and epithelial ovarian cancer risk was analyzed by odds ratio (OR) with a 95% confidence interval.
Results: The frequencies of AA, AG, and GG genotypes in ovarian cancer cases were 37.5%, 46.9%, and 15.6%, respectively, while that of control subjects were 56%, 36%, and 8%, respectively, in the study population. By taking the wild-type AA genotype as a reference, it was found that genotype GG was associated with a significant risk for epithelial ovarian cancer (OR: 2.92). Frequency distribution of genotypes did not show any significant association with tumor characteristics like the International Federation of Gynecology and Obstetrics (FIGO) stage, histology, lymph node status, and distant metastasis.
Conclusion: The present study demonstrated the association of MMP7 promoter site -181 GG genotype and the G allele with increased risk for epithelial ovarian cancer in the eastern Indian population.
