  Purpose

The objective of this clinical trial is to determine whether a Photoacoustic flow cytometry (PAFC)-based prototype device can detect circulating tumor cells (CTCs) in the blood of melanoma patients in vivo, in real time, and do so at detection limits at least one order of magnitude below the detection limits of currently existing ex vivo methods.

Primary Outcome Measures:
  • Number of participants that possess circulating tumor cells. [ Time Frame: 14-21 days ] [ Designated as safety issue: No ]

Estimated Enrollment: 75
Study Start Date: February 2013
Estimated Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts
Healthy control subjects
Characterize the baseline PA signals produced by the in vivo PAFC prototype device in healthy volunteers or Develop Standard Curves for the ex vivo CTC assays.
Advanced-Stage Melanoma
To validate the in vivo PAFC method of melanoma CTC detection, we will use the PAFC-based prototype device to noninvasively determine CTC concentrations in the blood of subjects who have advanced-stage (Stage III or Stage IV)melanoma, and we will also use current ex vivo methods to determine the CTC concentration in samples of blood drawn from the same subjects.
Early-Stage Melanoma
To determine whether in vivo PAFC can detect melanoma CTCs at concentrations below the detection limits of the ex vivo methods, we will use the PAFC-based prototype device to noninvasively detect CTCs in the blood of subjects who have early-stage (Stages I or II) melanoma, and we will also use current ex vivo methods to detect CTCs in samples of blood drawn from the same subjects.

Detailed Description:

Study Population: Approximately 80 subjects will be consented in order to achieve an enrollment goal of 75 subjects at this institution in three cohorts as follows:

  1. Cohort #1 will consist of fifteen healthy control subjects, ten of whom will be Caucasian and five of whom will be African-American. Subjects in cohort #1 will be used to address the calibration goal of Specific Aim #1.
  2. Cohort #2 will consist of 30 subjects who have advanced-stage melanoma will be recruited from the Medical Oncology clinic at UAMS, where advanced stages are defined as Stages III or IV. Subjects in cohort #2 will be used to address the validation goal of Specific Aim #2. Approximately half of the 30 advanced-stage subjects will be Stage III and the other half will be Stage IV.
  3. Cohort #3 will consist of 30 subjects with early-stage melanoma will be recruited from the Surgical Oncology clinic at UAMS, where early stages are defined as Stages I or II.

Subjects in cohort #3 will be used to address the detection goal of Specific Aim #3. Approximately 10 of the 30 early-stage subjects will be Stage I and approximately 20 will be Stage II.
