Quality of Life and Stigmatization in Children With Congenital Melanocytic Nevi Before and After Nevus Excision

March 2, 2026 updated by: University Children's Hospital, Zurich

Quality of Life and Experience of Stigmatization in Children With Congenital Melanocytic Nevi Before and After Nevus Excision: a Prospective Study

Congenital melanocytic nevi (CMN) are a quite common congenital disorder. Over years, surgical excision was proposed to the patients because transformation into a malignant skin tumor (melanoma) was feared. Recent data proof that the risk for malignancy was overestimated. Nowadays still a lot of patients express their wish for surgical removal out of aesthetic reasons and psychological impacts. Many patients and families experience stigmatization because of the nevus. To proof a medical indication for surgical removal the investigators want to evaluate the quality of life and stigmatization before and after nevus surgery.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

All children with CMN that will have their nevus removed in our surgical department will be asked to participate. The investigators will send a package of questionnaires to evaluate quality of life and stigmatization before nevus surgery. One year after surgical therapy is finished (sometimes more then one session is necessary), the scar will be clinically evaluated and also another questionnaire package will be sent to evaluate the same parameters again. All parameters are checked for the patients and the families as well. Therefore self and proxy reports of the parents are asked. Moreover, for the patients this is done with interviews in case they are older than 7 years.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

9 months to 16 years (Child)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

All patients with CMN of at least 2 square centimeter (projected adult size) that are scheduled for surgical removal of the CMN at our tertiary center for pediatric surgery.

Description

Inclusion Criteria:

  • patients with a congenital melanocytic nevi of at least 2 cm2 that will be removed surgically
  • age between 9 months and 16 years

Exclusion Criteria:

  • mental retardation of the child
  • insufficient knowledge of the German language of both parents
  • severe comorbidities
  • previous therapies done for the CMN (dermabrasion, surgery, laser)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of Quality of Life of affected children before and after surgery
Time Frame: Before surgery, up to 90 days after screening and one year after surgery
Quality of life with the CMN and in comparison with the scar after nevus excision is measured using validated age-related questionnaires respectively one-to one interviews
Before surgery, up to 90 days after screening and one year after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change of experiences of stigmatization before and after surgery
Time Frame: Before surgery, up to 90 days after screening and one year after surgery
Stigmatization experiences of patients and parents before CMN surgery in comparison with after nevus excision are measured using standardized and validated questionnaires
Before surgery, up to 90 days after screening and one year after surgery
Satisfaction with the treatment
Time Frame: One year after surgery
Satisfaction with the treatment is evaluated one year after the last surgical step using open questions with rating scales
One year after surgery

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2013

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
