Mole‐Mapping: Managing High‐Risk Patients through Imaging

• This session will focus on

utilizing imaging technology for the management of patients at “high‐risk” for melanoma

ABCD’s of Melanoma

A – Asymmetry B – Border Irregularity C – Color Variegation D – Diameter great than 6 mm

And E

E – Evolving

‐ Size ‐ Shape ‐ Symptoms ‐ Surface Bleeding ‐ Shades of Color

Defining a “High‐Risk” Patient

• North America Definition
• Personal History of Melanoma
• Family History of Melanoma
• Dysplastic Nevi
• Many Nevi
• Fair skin, inability to tan

Melanoma Statistics

• Increase in incidents rates
• It is estimated that the number of new melanoma cases diagnosed in 2019

will increase 7.7%

• Most new melanomas are de novo
• How can we spot them?

A recent study published in the JAAD shows that there is general agreement among Pigmented Lesion Experts recommending Total Body Photography and Dermoscopic Imaging for “high‐risk” patients.

Recommendation #1: Total body photography is recommended for patients with familial atypical multiple mole melanoma syndrome (FAMMM Syndrome, aka dysplastic nevus syndrome) Strongly Agree: 91% Agree: 0% Neither Agree nor Disagree: 9% Disagree: 0% Strongly Disagree: 0% Recommendation #1: Serial digital dermoscopic imaging is recommended for montioring "ugly duckling" nevi with equivocal dermoscopic features Strongly Agree: 55% Agree: 27% Neither Agree nor Disagree: 0% Disagree: 0% Strongly Disagree: 18% Recommendation #2: Total body photography is recommended in adults with > than 50 nevi that have one or more

• f the following: (1) a personal history of

multiple cutaneous melanomas; (2) a personal history of an amelanotic melanoma; multiple pink nevi, multiple clinically atypical nevi, and/or; (3) a genetic syndrome that predisposes to the development of cutaneous melanoma. Strongly Agree: 64% Agree: 36% Neither Agree no Disagree: 0% Disagree: 0% Strongly Disagree: 0% Recommendation #2: Serial digital dermoscopic imaging is recommended in patiets with a large or growing lentigo‐ like lesion that lack diagnostic dermoscopic features with a plan to re‐ evaluate at a three to six‐month interval Strongly Agree: 27% Agree: 55% Neither Agree no Disagree: 18% Disagree: 9% Strongly Disagree: 0% Total Body Photography Serial Digital Dermoscopic Imaging

What is Mole‐ Mapping?

• Combining multiple imaging techniques and

clinical follow‐up

• Total Body Photography
• Clinical Imaging
• Dermoscopic Imaging

1 + 1 = 3

Total Body Photography (TBP)

TBP – Photographic Medical Record

Creating a benchmark, similar to an EKG or x‐ray

Incidence of New and Changed Nevi and Melanomas Detected Using Baseline Images and Dermoscopy in Patients at High Risk for Melanoma

Jeremy P. Banky, MBBS; John W. Kelly, MDBS; Arch Dermatol. 2005;141:998-1006.

• The use of baseline photography and dermoscopy was associated

with low biopsy rates and early detection of melanomas. Only 3 nevi were biopsied for every melanoma.

• This compares to benign‐malignant ratios of 12:1 for dermatologists

and 30:1 for general physicians.

TBP – Identifying New Lesions

TBP – Identifying Changing Lesions

Underlying Rationale of using TBP

‐ Stable lesions are biologically indolent (senescent) ‐ New/Changing lesions are biologically relevant & may represent:

‐ Melanoma ‐ Melanoma Precursor

< 1‐3% new or changed lesions will be melanoma (clinical)

Patients who benefit from Total Body Photography

• Personal/Family History of melanoma
• Atypical/Dysplastic Nevi Syndrome
• Multiple Nevi of different size, shape, and color
• Patient’s with high anxiety of developing melanoma

Clinical/Dermoscopic Imaging

How good are skin cancer specialists at diagnosing melanoma based on visual examination alone?

• Sensitivity = 70%
• Specificity = 75%
• NNT (benign: malignant ratio) = 12-15

Diagnostic accuracy of melanoma may be improved with dermoscopy Pehamberger et al. 1993: diagnostic accuracy of 46‐54% (clinical) increasing to 62‐91% (dermoscopy)

How good are skin cancer specialists at diagnosing melanoma with aid of dermoscopy?

• Sensitivity = 90%
• Specificity = 86%
• NNT (benign:malignant ratio) = 4-7

Spectrum of Melanocytic Lesions

Nevi Malignant Melanoma

Clinical Exam

There are only a few clinical features which separate melanoma from nevi.

Nevi Malignant Melanoma

Lesions in the overlapping area often require a biopsy for diagnosis. Clinically Uncertain Lesions

Dermoscopic Exam

With dermoscopy there are dermoscopic features that correlate to benign or malignant patterns, thereby improving accuracy over clinical visual inspection

Nevi Malignant Melanoma Benign Patterns Malignant Patterns Intrinsic Limitation of Dermoscopy: Uncertain Patterns

Sometimes a dermatoscope isn’t enough

• Powerful tool to aid the diagnosis of early

melanomas

• High‐risk patients need more than a “point in

time” evaluation

Sometimes a dermatoscope isn’t enough

• How can you spot change

without reference images?

Short Term Surveillance

Image a suspicious melanocytic lesion that does not satisfy the classic dermoscopic criteria for the diagnosis of melanoma. The lesion is then re‐imaged at 3 month intervals. If a change is noted, the lesion is biopsied. It is believed that if a lesion is malignant, there will be a change within this time period without a significant risk to the patient.

The Value of Serial Digital Dermoscopic Imaging (SDDI)

Why use Mole Mapping?

• For Providers
• Increased Sensitivity & Specificity
• Reduced Benign‐to‐Malignant Ratio
• Time Restrictions
• For Patients
• Earlier Diagnosis
• No more “is that all?”
• Reduce Patient Anxiety

How to incorporate Mole Mapping into your Practice

There are many options:

• 1. The use of Electronic Medical Records
• 2. Outsourcing to imaging clinics
