Ovarian Pharmacoepidemiology ENCePP Protocol 1. Project Synopsis Project Title: Translating basic science into improved patient outcomes in ovarian cancer: an Ireland-UK collaboration investigating common pharmacological exposures and tumour characteristics, recurrence, survival and mortality. Research theme: Pharmacoepidemiology NCRI Staff Members: Mr Chris Brown, Dr Linda Sharp Funding source: Health Research Board Project duration: 2013 - 2015 Project Overview: By combining data from large pharmacoepidemiology databases in Ireland and the UK, will conduct a population-based study investigating associations between use of statins, beta-blockers and NSAIDs and ovarian cancer progression and outcome. This study will provide valuable population-based evidence on the effects of these common drugs on ovarian cancer and contribute to improved health outcomes for women affected by this cancer.

Ovarian Pharmacoepidemiology ENCePP Protocol 4. Project description Almost 250,000 ovarian cancers are diagnosed worldwide each year. Incidence rates are high in northern Europe, including in the Ireland and UK. These countries also have low survival and, consequently, among the highest ovarian cancer mortality rates in the world. The relatively young average age at diagnosis, advanced stage, and poor survival, means that ovarian cancer constitutes a major burden in terms of years of life lost. Research into factors that influence disease spread at diagnosis, and treatment response and survival would be of considerable
