Study arms

  • Other
    UV Counseling

    Evaluate the effectiveness of dosimetry feedback on sun exposure behaviors, attitudes, and awareness in patients diagnosed with melanoma.

    Behavioral: UV Counseling

  • Experimental
    Visual Analysis - UV Photo

    Assess the relationships between UV camera score, silicone mold of a skin patch, phenotypic evaluation and sun-exposure behaviors. Technically, this arm is a sub-study that does not involve an intervention. Patients are not receiving an intervention; they are simply providing data to the study team.

    Other: UV Photo

  • Experimental
    Biological Sample

    Determine the relationship between measures of sun exposure and genomic characteristics of tumors in melanoma patients. Technically, this arm is a sub-study that does not involve an intervention. Patients are not receiving an intervention; they are simply providing data to the study team.

    Other: Biological Sample

Interventions

  • BehavioralUV Counseling

    This is a sub-study that involves a behavioral intervention. Participants will wear a UV dosimetry for 3 weeks, return the device and receive feedback. After the feedback, they will re-wear the device for an additional 3 weeks.

  • OtherUV Photo

    Technically, this arm is a sub-study that does not involve an intervention. Patients are not receiving an intervention; they are simply providing data to the study team.

What researchers measure

Primary outcomes

  1. Sun Exposure Behaviors

    A short questionnaire is administered during the clinic visit to assess sun exposure behaviors of melanoma patients. The data gathered from this questionnaire will help identify possible trends in sun exposure behaviors and provide a baseline dataset for future research,

    Time frame: Start of study, initial interaction with participants.

  2. UV Exposure Assessment

    Identify the difference between self-reported sun exposure behavior and actual UV exposure by having patients wear individual dosimeters

    Time frame: Start of study to end of study, up to 6 weeks

  3. Visual Appearance Relationships: Melanoma, Questionnaire

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in melanoma patients using a sun exposure questionnaire

    Time frame: Start of study to end of study, up to 3 years

  4. Visual Appearance Relationships: Non-Melanoma , Questionnaire

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in non-melanoma patients using a sun exposure questionnaire

    Time frame: Start of study to end of study, up to 3 years

  5. Visual Appearance Relationships: Melanoma, Photography

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in melanoma patients using a UV photography

    Time frame: Start of study to end of study, up to 3 years

  6. Visual Appearance Relationships: Non-Melanoma, Photography

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in non-melanoma patients using a UV photography

    Time frame: Start of study to end of study, up to 3 years

  7. Visual Appearance Relationships: Melanoma, Casting

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in melanoma patients using a silicone casts

    Time frame: Start of study to end of study, up to 3 years

  8. Visual Appearance Relationships: Non-Melanoma, Casting

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in non-melanoma patients using a silicone casts

    Time frame: Start of study to end of study, up to 3 years

  9. Visual Appearance Relationships: Melanoma, SCINEXA

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in melanoma patients using a SCINEXA exam.

    Time frame: Start of study to end of study, up to 3 years

  10. Visual Appearance Relationships: Non-Melanoma, SCINEXA

    Determine the relationship between UV camera score, skin patch, sun exposure history, and phenotypic evaluation in non-melanoma patients using a SCINEXA exam.

    Time frame: Start of study to end of study, up to 3 years

  11. Genetics Correlations

    Determine whether UV exposure and camera scores correlates with UV signature (somatic) mutations and other tumor-related mutations in clinically benign nevi and primary melanomas using saliva samples, benign nevi, and primary melanomas. Next Generation Sequencing (NGS) will be used to obtain the genetic information from all samples.

    Time frame: Start of study to end of study, up to 3 years

Secondary outcomes

  1. Self Reporting Behaviors

    Determine self-reported sun exposure behaviors through participant interviews. Questions are related to time spent outside, and what attempts to be sun-safe occurred while outside.

    Time frame: Start of study to end of study, up to 3 years

  2. Behavioral Intervention and Immediate Follow Up

    Participants will receive a personalized feedback plan and the success of the plan will be measured through individual dosimetry. We will track real time change in sun exposure based on repeat UV dosimetry.

    Time frame: After wearing dosimetry for 3 weeks

  3. Benign Nevi, DNA

    Determine if a relationship exists between the phenotypic attributes of benign nevi through analysis of genomic DNA

    Time frame: Start of study to end of study, up to 3 years

  4. Benign Nevi, Mutations

    Determine if a relationship exists between the phenotypic attributes of benign nevi through analysis of somatic mutations

    Time frame: Start of study to end of study, up to 3 years

  5. Benign Nevi, Exposure

    Determine if a relationship exists between the phenotypic attributes of benign nevi through analysis of analysis of UV exposure history

    Time frame: Start of study to end of study, up to 3 years

  6. Benign Nevi, UV Camera

    Determine if a relationship exists between the phenotypic attributes of benign nevi through analysis of analysis of UV camera scores with the clinical presentation

    Time frame: Start of study to end of study, up to 3 years

  7. Primary Melanomas, DNA

    Determine if a relationship exists between the phenotypic attributes of primary melanomas through analysis of genomic DNA

    Time frame: Start of study to end of study, up to 3 years

    Determine if a relationship exists between the phenotypic attributes of primary melanomas through analysis of UV exposure history

    Time frame: Start of study to end of study, up to 3 years

  10. Primary Melanomas, UV Camera

    Determine if a relationship exists between the phenotypic attributes of primary melanomas through analysis of UV camera scores with the clinical presentation

    Time frame: Start of study to end of study, up to 3 years
