Brief Summary
Phase I trial to study the effectiveness of photodynamic therapy with lutetium texaphyrin in treating patients who have cervical intraepithelial neoplasia. Photodynamic therapy uses light and drugs such as lutetium texaphyrin that make abnormal cells more sensitive to light and may kill abnormal cells in the cervix and prevent the development of cervical cancer

Outcome Measures
Primary Outcomes (3)
Optimal dosage with the least toxicity of lutetium texaphyrin (Part 1)
A simplified graphical analysis will be utilized to determine the drug dose and time after administration that provides the largest differential area between lutein texaphyrin tissue levels in neoplastic and normal cervical tissue
Up to 24 hours
Maximal differential in Lutrin tissue levels between normal and dysplastic cells (Part 1)
At the time of LEEP
Percentage of tissue demonstrating PDT related effects (apoptosis/ necrosis) for normal versus abnormal epithelium at each total fluence for each LEEP cone biopsy specimen
A simplified graphical analysis will be utilized to determine the fluence that provides the maximal differential area between neoplastic and normal cervical epithelium and stroma.
At LEEP time
Study Arms (2)
Part 1 (lutetium texaphyrin, LEEP)
EXPERIMENTALPatients receive lutetium texaphyrin IV over 5-20 minutes. Patients undergo in vivo tissue assessment by spectrometer at 0, 1, 3, 5, 12, and 24 hours and loop electrical excision procedure (LEEP) at 24 hours after lutetium texaphyrin infusion.
Part 2 (lutetium texaphyrin, laser therapy, LEEP)
EXPERIMENTALPatients receive lutetium texaphyrin IV over 5-20 minutes. A laser delivers 730 nm of light to the cervix for 4, 8, or 16 minutes. Patients undergo LEEP at 4, 8, or 12 hours after exposure of the cervix to the light source.
