Transcriptomic analysis of ovarian tumor pairs from primary and metastatic lesions. Transcriptomic analysis of ovarian tumor pairs from primary and metastatic lesions

Ovarian cancer is one of the most lethal gynaecological malignancies among female population. The high mortality rate of this disease is due to its poor prognosis and most patients present at an advanced stage accompanied with metastasis. The frequent tumor recurrence rate associated with metastasis and chemoresistance are the major obstacles in clinical management of the disease. Different from other solid tumors, ovarian cancer perfers transcoelomic metastasis amd mounting evidence has suggested ovarian cancer patients who have peritoneal metastasis are usually poor prognosis and highly chemoresistant recurrence. In this study, we examined the differential gene expression profile between the primary tumors and their paired metastastic lesions with a view to discover novel target therapies in combating ovarian cancer. Overall design: mRNA profile of 5 pairs of ovarian tumors from primary and omental metastasis were analysed.
