Predicting the recurrence of localized melanoma is important; however, studies investigating risk factors for recurrence of localized melanoma are lacking in Asian populations.
To identify risk factors for recurrence of localized melanoma in Korean patients.
We retrospectively reviewed patients with cutaneous melanoma without evidence of metastasis from 2000 to 2017. Logistic and Cox regression analyses were conducted for recurrence. The average follow-up time was 46.2 months.
We reviewed the data of 340 patients diagnosed with cutaneous melanoma and staged as melanoma in situ, stages I and II. Acral melanoma (70.3%, 239/340) was the predominant subtype. Ninety-two patients (27.1%) had a recurrence after primary melanoma removal (29 local recurrences, 49 regional metastases, and 28 distant metastases). Some patients had multiple types of recurrence at the same time. Male sex (P = .030) and Breslow thickness greater than 1 mm (P = .008) correlated with an increased risk of recurrence. Breslow thickness greater than 2.5 mm in males and greater than 4 mm in females showed a higher predictive value for recurrence than traditional stages IIB and IIC (hazard ratio 3.743 vs 2.972).
This was a single-center retrospective study.
In patients with localized cutaneous melanoma, male sex and Breslow thickness are the most important prognostic factors for recurrence in Korean populations. Different cutoff values of Breslow thickness may better predict recurrence according to sex.Le texte complet de cet article est disponible en PDF.
