About this study
Official title: Use of Fluorescence Imaging and High-Resolution Microendoscopy to Guide Hysteroscopic Tumor Resection in Patients With Endometrial Cancer
The goal of this clinical research study is to learn if imaging (called a hysteroscopy) can be used to help guide tumor removal during a hysterectomy.
Read the detailed description
Tissue Collection and Imaging:
If participant is found to be eligible to take part in this study, during their standard-of-care hysterectomy, a tissue sample will be collected. This sample will be used for research and routine testing. Participant will sign a separate consent form for the hysterectomy.
During the hysterectomy, photographs of the tissue will be taken. Participant's private areas will be covered (as much as possible), and a picture of their face will not be taken.
A hysteroscopy will also be performed during participant's surgery. Participant's doctor will discuss the risks of the hysteroscopy with participant and they will be asked to sign a separate consent form. A hysteroscopy allows the doctor to look inside the uterus to see the tissue that is going to be collected for research imaging. This procedure is done with a tool called a hysteroscope, a long thin tube with a camera and a light. The hysteroscope will be inserted though the vagina and up into the uterus. An image will be displayed on a computer screen that is attached to the hysteroscope. The study doctor will use the image on the screen to look at different areas of the uterus to find the location and size of the tumor(s). This image may be recorded for future reference.
After the hysteroscopy, the study doctor will inject a contrast dye (Proflavine Hemisulfate) into participant's uterus to help the doctor see the lesions. A camera will then be used to photograph images of the uterus.
The tissue collection and the imaging will add about 45 minutes to participant's hysterectomy procedure.
Length of Study:
Patient's active participation in this study will be over after surgery.
Follow-Up Call:
About 30 days (+/-7 days) after the surgery, participant will be called and asked how they are doing.
This is an investigational study. The hysteroscope is commercially available and FDA approved for laparoscopic procedures. The use of the hysteroscope in this study is for research purposes only.
Proflavine Hemisulfate (contrast dye) is commercially available and FDA approved for treating umbilical cord stumps. Its use in this study is considered investigational.
Up to 20 participants will be enrolled in this study. All will take part at MD Anderson.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High-Resolution Microendoscopy ImagingProcedure or surgery
Also called HRME
Once the cervix has been dilated, a hysteroscope will be introduced in the uterine cavity to evaluate for presence of tumor. Location and size of tumor documented. White-light images obtained using the HRME camera introduced through the hysteroscope. Once completed; the hysteroscope will be removed and the uterine cavity will be infused with 10 mL of proflavine (an acridine dye) (0.01% Proflavine (10ml)). A resectoscope will then be introduced in the uterine cavity and fluorescent images obtained using the HRME camera.
ProflavineDrug
After hysteroscopy with HRME camera, uterine cavity infused with 10 mL of Proflavine.
| Study group | Role | What they receive |
|---|---|---|
| Hysteroscope Imaging | Experimental | All patients entered in study will undergo cervical dilation after induction of general anesthesia. Once the cervix has been dilated, a hysteroscope will be introduced in the uterine cavity to evaluate for presence of tumor. Location and size of tumor documented. White-light images obtained using the High-Resolution Microendoscopy (HRME) camera introduced through the hysteroscope. Once completed; the hysteroscope will be removed and the uterine cavity will be infused with 10 mL of proflavine (an acridine dye) (0.01% Proflavine (10ml)). A resectoscope will then be introduced in the uterine cavity and fluorescent images obtained using the HRME camera. The resectoscope will then be used to remove all tumor as guided through HRME images. The entire imaging and tumor resection process is estimated to take 45 minutes or less. Receives: Procedure: High-Resolution Microendoscopy Imaging; Drug: Proflavine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Absence of Residual Disease in Hysterectomy Specimen
Descriptive statistics used to summarize the expression in tumor tissue and in normal tissue for each of the molecular markers assessed, as well as the difference in tumor and normal tissue within patient. Paired t-test used to compare the tumor and normal tissue with respect to the mean difference in expression of each marker, pairing tumor and normal tissue on patient. Boxplots used to illustrate the distribution of the difference in expression in tumor and normal tissue for each marker.
Measured: 1 day

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing High-Resolution Microendoscopy Imaging and Proflavine in people with Uterine Cancer, run by M.D. Anderson Cancer Center.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 8 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Absence of Residual Disease in Hysterectomy Specimen (time frame: 1 day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2015.
