Trial summary

The incidence of malignant melanoma has increased dramatically in recent decades. In 1930, the lifetime risk of an individual in the United States developing melanoma was 1 in 1,500. This has been exponentially increasing over the years with the risk estimated to be 1 in 75 in 2000 . Read more about this study

About this study

Official title: A Pilot Study to Evaluate the Correlation Between Modified Two Layer Diffuse Optical Spectroscopy With the Clinical and Histological Examinations of Pigmented Skin Lesions Based on Physiological Parameters

The incidence of malignant melanoma has increased dramatically in recent decades. In 1930, the lifetime risk of an individual in the United States developing melanoma was 1 in 1,500. This has been exponentially increasing over the years with the risk estimated to be 1 in 75 in 2000 . According to the American Cancer Society, approximately 59,580 new cases of melanoma will be diagnosed in the United States in 2005 and about 7,770 people are expected to die of the disease.

Read the detailed description

The researcher ucan use special imaging devices to obtain information about a typical mole and melanoma and use this information to determine the different between malignant and benign melanized lesions. The imaging devices are, Modified Two Layer Diffuse Optical Spectroscopy,multi-spectral imaging, and Spatially Modulated Quantitative Spectroscopy can use to measure atypical moles and melanoma and correlate the results of the biopsy tissue histology.

The imaging devices can quantify melanin, oxy and deoxy hemoglobin concentration, water, lipid and reduced scattering coefficients and can compare results to histopathologic. Atypical moles and melanoma have a different optical profile based on physiological parameters compared to benign nevus.

Questions about this trial

What is this clinical trial studying?

An observational study of Skin Cancer, run by University of California, Irvine at 2 sites in United States.

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 2 inclusion and 2 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: finished, as of the sponsor's last update on 1 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Measure atypical moles and melanoma (time frame: 4 weeks). 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 1 Nov 2022.
