RESUMO

Objetivo:

Comparar as modalidades diagnósticas do PET-CT com 68Ga-DOTATATE versus cintilografia em gama camera com 111In-octreotide nos pacientes portadores de tumores neuroendócrinos e a avaliação da medida do seu impacto na mudança de terapia.

Método:

Quarenta e um pacientes com tumores neuroendócrinos confirmados histologicamente foram incluidos e foram submetidos a cintilografia convencional com 111In-octreotide e PET-CT de corpo inteiro com 68Ga-DOTATATE. Imagens de ambas as modalidades foram comparadas em uma análise paciente a paciente com avaliação do impacto da detecção de lesões adicionais na mudança de conduta.

Resultados:

Significativamente mais lesões foram detectadas no PET-CT com 68Ga-DOTATATE quando comparado a cintilografia convencional com 111In-octreotide. Lesões adicionais foram mais frequentemente visualizadas no fígado e nos implantes em alças intestinais. Mudanças na conduta devido a informações adicionais oferecidas pelo PET-CT com 68Ga-DOTATATE ocorreram em cinco dos 41 pacientes (12,2%). Três dos 41 pacientes (7,3%) apresentaram mudança de conduta intermodalidade e dois dos 41 (4,9%) mudança intramodalidade.

Conclusão:

O PET-CT com 68Ga-DOTATATE demonstrou-se superior para a detecção de tumores neuroendócrinos comparativamente à cintilografia convencional com 111In-octreotide, traduzida em parte na mudança de conduta terapêutica
ABSTRACT

Purpose:

Compare the detectability of the 68Ga-DOTATATE PET-CT with conventional 111In-octreotide scintigraphy in neuroendocrine tumors patients carrier and the measure of its impact in therapy change.

Method:

Forty one patients with a histologically confirmed diagnosis of neuroendocrine tumors were included and underwent conventional 111In-octreotide scintigraphy and whole body 68Ga-DOTATATE PET-CT. Images of both modalities were compared in a patient by patient analysis determining aditional lesions and the impact of detecting additional lesions in the therapy change.

Results:

Significantly more lesions were detected on 68Ga-DOTATATE PET-CT versus conventional 111In-octreotide scintigraphy. Additional lesions were mostly frequent visualized in liver and implants in intestinal loops. Change in management due additional information given by 68Ga-DOTATATE PET-CT occured in 5 of 41 patients (12.2%). Three of 41 patients (7.3%) presented a intermodality change and 2 of 41 (4.9%) had a intramodality change.

Conclusion:

68Ga-DOTATATE PET-CT is superior for the detection of neuroendocrine tumors compared to conventional 111In-octreotide scintigraphy with impact in the therapy change
