Spectroscopy in Ovarian Cancer

Study Overview
=================
Brief Summary
-----------------
Ovarian cancer is the eighth most common cause of cancer death in the world. Advanced stage at diagnosis is associated with lower survival rates, thus early detection appears to have an important role. Raman Spectroscopy is a non-invasive technique that uses the interaction of light to identify the composition of the sample tested. The aim of the project is to explore the use of spectroscopic techniques in the detection of ovarian cancer. There are two different assessments within the project: Identify ovarian cancer in blood - Raman spectroscopic analysis will be performed on blood plasma taken from patients with suspected ovarian cancer. Detect active cancer within post chemotherapy fibrotic tissue - Ex vivo Raman spectroscopic analysis of peritoneal, omental or ovarian tissues collected from patients undergoing surgical treatment for ovarian cancer. The results of the spectroscopy will be correlated to clinical outcome and histological diagnosis respectively.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ascertain the diagnostic performance of vibrational spectroscopy for detection of Ovarian Cancer | Biomarkers for ovarian cancer will be identified by analysing Raman spectral data of plasma samples taken from patient with ovarian cancer symptoms. Clinical outcome of cancer/no cancer will be used to correlate the results. | 2 years | 
| Ascertain the discriminatory ability of vibrational spectroscopy to differentiate between normal, fibrotic and cancerous tissue | Samples taken from post chemotherapy patients will be analysed to identify the spectral signature of ovarian cancer in chemotherapy exposed tissue. | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Performance of vibrational spectroscopy in chemotherapy response prediction | Plasma samples after 1st cycle of chemotherapy will be analysed to evaluate for changes in biomarkers after chemotherapy treatment. | 2 years | 
| Performance of vibrational spectroscopy in recurrence prediction | Plasma samples after recurrence of cancer will be analysed and compared to initial spectral signature at diagnosis | 2 years |
