ABSTRACT: Once individuals are diagnosed with malignant melanoma, they are at an increased risk of developing another melanoma when compared with the normal population. To determine the impact of an intensive follow-up protocol on the stage of disease at diagnosis of subsequent primary melanomas, a retrospective query was performed of an electronic medical record database of 2,600 consecutively registered melanoma patients. Sixty-seven patients (2.6%) had another melanoma diagnosed at the time of presentation to the clinic or within 2 months (synchronous) and another 44 patients (1.7%) developed a second primary melanoma during the follow-up period (metachronous). For the 44 patients diagnosed with metachronous lesions, the Breslow mean tumor thickness for the first invasive melanoma was 2.27 mm compared with 0.90 mm for the second melanoma. The first melanomas diagnosed are thicker by an average of 3.8 mm (p = 0.008). The mean Clark level for the initial melanoma was greater than the mean level for subsequently diagnosed melanomas (p = 0.002). Twenty-three percent of the initial melanomas were ulcerated, whereas only one of the second primary lesions showed this adverse prognostic factor (p = 0.002). Once individuals are diagnosed with melanoma, they are in a high-risk population for having other primary site melanomas diagnosed and should be placed in an intensive follow-up protocol consisting of a complete skin examination.Annals of Surgical Oncology 02/1997; 4(1):19-23.

ABSTRACT: To assess the frequency of occurrence and risk factors for multiple primary melanoma. Population-based, case-control study. New Hampshire. Three-hundred fifty-four New Hampshire residents with a confirmed first diagnosis of cutaneous melanoma. Diagnosis of a subsequent primary cutaneous melanoma. An additional melanoma occurred in 27 individuals (8%) within 2 years of their initial diagnosis, including 20 (6%) within the first postdiagnosis year. In 9 (33%) of these 27 cases, at least 1 subsequent melanoma was deeper than the first tumor. The 27 individuals with a subsequent melanoma diagnosis were classified as "cases" and were compared on the basis of risk factors to the 327 "controls" with a single melanoma diagnosis. The data indicate an inverse relation of risk of multiple primary melanomas with multiple blistering sunburns (P = .01 for the trend); the odds ratio (OR) was 0.32 (95% confidence interval [CI], 0.11-0.93) for 2 or more sunburns compared with none. The number of atypical moles was significantly related to increased risk (P = .004 for the trend). The presence of 3 or more atypical moles compared with none was associated with more than a 4-fold risk of multiple primary melanomas (OR, 4.29; 95% CI, 1.51-12.16). Additional melanomas occur more frequently than previously shown. Our study confirms that atypical moles are strongly associated with risk of multiple primary melanomas but provides little evidence that risk is influenced by pigmentary characteristics, hours of sun exposure, or benign moles. The inverse association with blistering sunburn may reflect the influence of an unmeasured covariate.Archives of Dermatology 05/2006; 142(4):433-8. DOI:10.1001/archderm.142.4.433 · 4.79 Impact Factor
