Resumo

 O cancro do esófago (CE) é um cancro comum em Moçambique, sendo os carcinomas de células escamosas do esófago (CCEE) o subtipo mais frequente deste cancro. Pouco se sabe sobre o impacto do vírus da imunodeficiência humana (VIH) nesta patologia. O principal objetivo deste estudo foi avaliar a associação entre CE e infeção pelo VIH.


Métodos: Um estudo de caso-controlo foi conduzido, em 2018, no Hospital Central de Maputo, Moçambique (HCM). Adultos que consentiram em participar foram considerados elegíveis. Doentes com CCEE que realizaram teste de VIH constituíram o grupo de casos. Os controlos foram selecionados entre os doentes com condições benignas cirúrgicas que seriam operados no HCM, tendo sido emparelhados por sexo e idade. Os testes de qui-quadrado ou exato de Fisher foram utilizados para avaliar potenciais associações entre duas variáveis categóricas. Para realizar comparações entre grupos foi utilizado o teste t para amostras independentes ou o teste de Mann-Whitney para as variáveis contínuas. A razão de chances (OR) e o respetivo intervalo de confiança de 95% (IC) foram calculados usando regressão logística não-condicional. Um valor de p < 0,05 foi considerado significativo.
Resultados: Durante o período de estudo, 92 casos e 92 controlos foram incluídos no estudo. 67,4% dos casos eram do sexo feminino. A idade mediana dos casos e dos controlos foi de 57 (35-83) e 52 (35-85) anos, respetivamente. O diagnóstico de VIH positivo aumentou significativamente as chances de desenvolver CE, principalmente nas mulheres (OR=4,81; IC 95%: 2,24–10,32; p<0,001), mas o mesmo não ocorreu nos homens (OR=2,26; IC 95%: 0,80–6,36; p=0,123).
Conclusão: O cancro do esófago e o vírus da imunodeficiência humana são comuns em Moçambique. A infeção por VIH é um potencial fator de risco para CCEE, principalmente no sexo feminino. Pacientes com VIH e outros fatores de risco, como a exposição ao fumo doméstico ou do tabaco, devem ser educados e acompanhados para um diagnóstico precoce do cancro do esófago.
