ABSTRACT

BACKGROUND:

There is an improvement on the GIST treatment in last decade due to biomolecular research and adjuvant therapy with tyrosine kinases inibitors. However, both modalities of treatment rarely are available in Brazilian public hospital.

AIM:

Evaluate GIST patients profile in public oncologic hospital.

METHODS:

A retrospective study was made on patients with GIST diagnosed and treated between 2001 and 2013.

RESULTS:

Sixty-nine patients were included, mean age 59 years with slight predominance in females (51%). The main symptom was abdominal pain associated with incidental imaging finding. The occurrence of other associated neoplasm was in 28.8% of cases. The positivity of CD117 was 97.1%. The most frequent location was the stomach in 55.1% of cases. The R0 resection was possible in 63.8% and the recurrence rate was 20.3 %, with liver and peritoneum the main affected sites. Overall survival in the whole sample was 71%. Free survival rate of disease was 64%. The use of imatinib was limited to patients with residual disease (unresectable disease, R2 and R1 resection), metastatic disease or recurrence.

CONCLUSION:

In order to improve GIST treatment is necessary to add the biomolecular analysis to risk stratification. However, for this to occur, incentive in biomolecular research is required, to increase the possibility of patient survival. .
RESUMO
RACIONAL O tratamento do GIST tem se aprimorado muito na última década através das pesquisas biomoleculares e o uso adjuvante dos inibidores das tirosinas quinases. Entretanto, nos hospitais públicos brasileiros nem sempre são disponíveis tais ferramentas.

OBJETIVO:

Avaliar o perfil dos pacientes portadores de GIST em hospital público oncológico.

MÉTODOS:

Análise retrospectiva de todos os casos de GIST tratados no período de 2001 a 2013.

RESULTADOS:

Analisaram-se 69 pacientes, com média de idade de 59 anos e com discreto predomínio no sexo feminino (51%). A principal forma de apresentação clínica foi dor abdominal associada com achado de exame de imagem. A ocorrência de outra neoplasia associada foi de 28,8%. A positividade do CD117 foi de 97,1%. A localização mais frequente foi o estômago em 55,1%. A ressecção R0 foi possível em 63,8% dos casos e a taxa de recidiva foi de 20,3%, sendo fígado e peritôneo os sítios principais acometidos. A sobrevida global na amostra toda foi de 71%. A taxa de sobrevida livre de doença foi de 64%. A utilização do imatinibe ficou restrita aos pacientes com doença residual (ressecção R2, R1 ou metastáticos), irressecáveis ou com recidiva.

CONCLUSÃO:

Afim de aprimorar o tratamento do GIST é necessário acrescentar a análise biomolecular à estratificação de risco. Porém, para que isto ocorra, políticas de incentivo e fomento na pesquisa biomolecular são necessárias, ampliando a possibilidade de sobrevida dos pacientes. .
