ABSTRACT Objectives:

to analyze the survival in juvenile melanoma.

Methods:

retrospective study conducted by hospital record review and cancer records of patients aged 0 to 19 years, with histologically proven melanoma and treated between 1997 and 2017 at the Erasto Gaertner Hospital in Curitiba-PR.

Results:

the sample comprised 24 patients, female (62.5%), mean 14.14 ± 4.72 years old, with head and neck melanoma (37.5%), chest (25%) and extremities. (20.8%). Signs and symptoms at diagnosis were increased lesion size (25%), bleeding (20.8%) and pruritus (16.6%). There was a Breslow II and IV index and Clark IV level, with a statistical tendency between Breslow IV and death (p = 0.127), and significance between Clark V and death (p = 0.067). Nine (37.5%) patients had metastases, six (25%) with distant metastases died (p = 0.001), five were girls (20.8%). Surgery was the standard treatment and chemotherapy the most used adjuvant (37.5%). The average time between diagnosis and death was 1.3 ± 1.2 years and survival were 3.7 ± 3.2 years.

Conclusion:

there was a delay in diagnosis, high morbidity and mortality and average survival less than five years.

RESUMO Objetivos:

analisar a sobrevida no Melanoma Infantojuvenil.

Métodos:

estudo retrospectivo realizado mediante revisão de prontuários e registros hospitalares de câncer, de pacientes na faixa etária de 0 a 19 anos, com melanoma comprovado histologicamente e atendidos entre 1997 e 2017 no Hospital Erasto Gaertner em Curitiba-PR.

Resultados:

amostra composta por 24 pacientes, sexo feminino (62,5%), média de 14,12 ± 4,72 anos de idade, com melanoma em cabeça e pescoço (37,5%), tórax (25%) e extremidades (20,8%). Os sinais e sintomas ao diagnóstico foram aumento do tamanho da lesão (25%), sangramento (20,8%) e prurido (16,6%). Ocorreu Índice de Breslow II e IV e Nível de Clark IV, com tendência estatística entre Breslow IV e óbito (p=0,127) e significância entre Clark V e óbito (p=0,067). Nove (37,5%) pacientes apresentaram metástases, seis (25%) com metástases à distância morreram (p=0,001), cinco eram meninas (20,8%). A cirurgia foi o tratamento padrão e a quimioterapia o adjuvante mais utilizado (37,5%). A média de tempo entre diagnóstico e óbito foi de 1,3 ± 1,2 anos e de sobrevida foi 3,7 ± 3,2 anos.

Conclusão:

houve atraso no diagnóstico, alta morbimortalidade e média de sobrevida menor do que cinco anos.
