Photoacoustic Imaging in Diagnosing Changes in Tumors in Participants With Breast Cancer, Sarcoma, Skin Cancer, or Soft Tissue Malignancy and Healthy Volunteers

Not Applicable

Terminated

• Conditions: Healthy Subject; Breast Carcinoma; Malignant Soft Tissue Neoplasm; Sarcoma; Skin Carcinoma
• Interventions: Procedure: Photoacoustic Imaging

• Registration Number: NCT03630601
• Lead Sponsor: Roswell Park Cancer Institute

Brief Summary

This pilot trial studies how well photoacoustic imaging works in diagnosing changes in tumors in participants with breast cancer, sarcoma, skin cancer, or soft tissue malignancy and healthy volunteers. Photoacoustic imaging is a low-risk imaging method that provides information about the oxygenation of tissues using a combination of light and ultrasound techniques. Photoacoustic imaging uses a signal from hemoglobin to provide information on blood flow and oxygen levels, and it may be helpful in determining changes in tumors after chemotherapy or radiation treatment.

Detailed Description

PRIMARY OBJECTIVES:

I. To define the feasibility of the current photoacoustic imaging (PAI) technology in various groups of human subjects.

SECONDARY OBJECTIVES:

I. To define the utility of the current PAI on various groups of human subjects.

II. When possible, via means of an existing data review, PAI will be correlated with standard imaging modalities performed on patients as routine part of clinical care or on protocol.

III. When possible, via means of an existing data review, PAI will be compared to pathologic specimens.

IV. When possible, via means of an existing data review, PAI data will be correlated with outcomes of patients to therapies they receive.

OUTLINE:

Participants undergo PAI on different parts of the body over 20 minutes for up to 5 imaging sessions for 6 months.

Arm && Interventions

Group	Intervention	Description
Diagnostic (photoacoustic imaging)	Photoacoustic Imaging	Participants undergo PAI on different parts of the body over 20 minutes for up to 5 imaging sessions for 6 months.

Primary Outcome Measures

Name	Time	Method
Feasibility of photoacoustic imaging (PAI) to quantify tumor characteristics	Up to 6 months	This will be deemed a success if at least 3 imaging sessions produce a usable image. Usable datasets will be defined as those images with detectable PAI signal with minimal or no artifacts within the region of interest. This analysis will be done in the imaged sample, consisting of enrolled patients who attempt at least one imaging session. Patients who do not attempt at least one imaging session will be replaced.

Secondary Outcome Measures

Name	Time	Method
Utility of serial PAI measurements	Up to 6 months	This will be explored by comparison with disease and outcome characteristics collected during routine cancer treatment, including standard imaging modalities, pathology results, and clinical outcomes. Results of these analyses are intended to inform development of early stage (Phase 1/2) clinical trials that consider PAI summaries as biomarkers for treatment response.
Serial PAI oxygenation measurements	Up to 6 months	This will be correlated with disease and patient characteristics using Cox Regression models for progression and overall survival.
