Clinical Trial Summary

This study is being conducted to validate if photoacoustic imaging potentially reduces benign surgeries without compromising cancer detection sensitivity. The study will also explore whether using the photoacoustic imaging/ultrasound technique has any potential with early ovarian cancer detection in a group of high risk patients.

Description:

In primary and secondary objectives, the investigators will consent patients who are at risk for ovarian cancer, or who have an ovarian mass possibly suggestive of a malignancy and are counseled to undergo oophorectomy. Patients will be identified by the GYN physicians and consented by the study coordinator prior to the date of the scheduled surgical procedure. In exploratory objectives, the investigators will consent patients who are at risk for ovarian cancer and wish to be followed before making decision to undergo prophylactic oophorectomy. Patients will be identified based on the eligibility criteria by the physicians and consented by the study coordinator prior to the follow up studies.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Determine if co-registered PAI/US can be used as a sensitive and specific screening tool for early detection of malignant neoangiogenesis within a group of high-risk women	The investigators hope to improve current practice by detecting early cancers from this group of high-risk women	Through completion of follow-up (estimated to be 4.5 years)
Other	Determine normal changes of photoacoustic imaging parameters	The investigators expect to see small changes of the PAI/US imaging parameters of less than 10-15 for repeated measurements of 3 menstrual cycles	Through completion of follow-up (estimated to be 4.5 years)
Primary	Assess the impact of co-registered PAI/US on the potential reduction of benign surgeries as measured by the area under receiver characteristic curve (AUC)	The anticipated improvement of diagnostic accuracy on reduction of surgeries of benign ovaries will be from current practice of AUC=55% to AUC=78%.	At the time of surgery (estimated to be 2 weeks)
Secondary	False negative rate of conventional imaging compared to conventional imaging & PAI/US as measured by sensitivity of cancer detection	The anticipated improvement of cancer detection accuracy will be from current practice of 80% to 94%.	At the time of surgery (estimated to be 2 weeks)
