RESUMO

OBJETIVO:

Estudar a frequência de neoplasias em uma amostra da população brasileira feminina com lúpus eritematoso sistêmico.

MÉTODOS:

Este é um trabalho retrospectivo de revisão de prontuários de 395 mulheres com lúpus eritematoso sistêmico, diagnosticadas pela presença de, pelo menos, 4 dos critérios classificatórios do Colégio Americano de Reumatologia para diagnóstico dessa doença e acompanhadas nos últimos 10 anos em um ambulatório especializado em Reumatologia. Foram coletados dados demográficos (idade e etnia das pacientes), dados acerca de duração de doença, de uso dos principais imunomoduladores e de diagnóstico de neoplasias. As informações obtidas foram tabuladas em tabelas de frequência e de contingência. A taxa de incidência de neoplasias nas mulheres com lúpus foi comparada com a da população em geral para a mesma região demográfica, nos últimos dez anos, utilizando, para isso, dados publicados pelo Instituto Nacional de Câncer (INCA). A associação dos dados foi feita pelos testes de Fisher e do χ2, quando os dados eram nominais, e de Mann-Whitney, quando numéricos. Foi adotada a significância de 5%.

RESULTADOS:

Foram identificados 22 casos de tumores malignos (22 casos/395 ou 5,5% da amostra) sendo os mais comuns os de útero (10 casos/395 ou 2,5% da amostra) e de mama (9 casos/395 ou 2,2% da amostra). A presença de tumores estava associada com tempo de duração de doença (p=0,006), não sendo observada influência de tratamento com metotrexate (p=0,1), azatioprina (p=0,9), ciclofosfamida (p=0,6) e glicocorticoides (p=0,3). Os tumores de mama e de colo do útero foram mais comuns no lúpus eritematoso sistêmico do que na população em geral (p<0,0001 para ...
ABSTRACT

PURPOSE:

To study the incidence of tumors in a Brazilian sample of women with systemic lupus erythematosus.

METHODS:

This is a retrospective study of 395 medical charts from women with systemic lupus erythematosus diagnosed by the presence of at least 4 of the American College of Rheumatology classification criteria for the diagnosis of this disease and followed for the last 10 years in a rheumatology outpatient clinic. Demographic data (age and ethnicity of patients), data on disease duration, use of immunomodulators and on the presence of neoplasms were listed. Results are presented in frequency and contingency tables. The incidence rate of malignancies in women with lupus was compared with that of the general population for the same demographic region for the past ten years, using data published by the Brazilian National Cancer Institute (INCA). Association studies were carried out by the Fisher and χ2 tests, when the data were nominal, and by Mann-Whitney test, when numeric. The level of significance was set at 5%.

RESULTS:

Twenty-two cases of malignant tumors were identified during these 10 years of follow-up (22 cases/395 or 5.5% of the sample), being the most common those of the uterine cervix (10 cases/395 or 2.5% of the sample) and breast cancer (9 cases/395 or 2.2% of the sample). The presence of tumors was associated with disease duration (p=0.006) and was not influenced by treatment with methotrexate (p=0.1), azathioprine (p=0.9), cyclophosphamide (p=0.6) and glucocorticoids (p=0.3). Breast and uterine cervix tumors were more common in systemic lupus erythematosus women than in the general population (p<0.0001 for both).

CONCLUSION:

A high prevalence of malignant tumors was found in this sample, with tumors being more common in patients with longer disease duration. The most frequent tumors affected the breast and uterus at a higher incidence than in the general population. The presence of tumors was ...
