ABSTRACT

INTRODUCTION:

The previous radio-chemotherapy approach is highly relevant in the management of rectal cancer, collaborating on organ functional preservation, being performed prior to surgery. The inflammatory response plays an important role in this treatment.

OBJECTIVE:

It consists in correlating the number of peripheral lymphocytes and the neutrophil/lymphocyte ratio in the peripheral blood with tumor response to neoadjuvant therapy.

METHODS:

Review of medical records of patients with rectal cancer in HMSJ and HSJ Oncology Services since 2009 - cases submitted to neoadjuvant treatment with radio-chemotherapy.

RESULTS:

Of those 96 patients with this disease who underwent neoadjuvant therapy with radio-chemotherapy, 35 patients were eligible; complete tumor response was observed in 11 cases (31%), and 9 were submitted to surgical treatment. Comparing the leukocyte parameters between patients with complete response (CR) and incomplete response (IR) the following values were observed total number of leukocytes (mean) CR 7390.9 × IR 7220.4 (p = 0.8); total lymphocytes CR 2103 × IR 1960.9 (p = 0.4); neutrophil/lymphocyte ratio CR 3.55 × IR 3.79 (p = 0.5). The mean radiotherapy dose was 49.1 Gy, with CR 47.3 × IR 50.0 (p = 0.06).

CONCLUSION:

It was not possible to demonstrate in this study a significant relationship between complete tumor response to neoadjuvant therapy with respect to blood leukocyte parameters analyzed. (AU)
RESUMO

INTRODUÇÃO:

A abordagem radio-quimioterápica previa apresenta grande relevância no manuseio do câncer de reto, colaborando na preservação funcional do órgão, sendo realizada previamente à cirurgia. A resposta inflamatória tem papel importante neste tratamento.

OBJETIVO:

Consiste em correlacionar o número de linfócitos periféricos e a relação neutrófilos/linfócitos no sangue periférico com a resposta tumoral à terapia neo-adjuvante.

MÉTODOS:

Revisão de prontuários dos pacientes portadores de câncer retal dos serviços de Oncologia do HMSJ e HSJ, desde 2009, casos submetidos ao tratamento neo-adjuvante com radio-quimioterapia.

RESULTADOS:

Do total de 96 pacientes portadores desta enfermidade, submetidos à terapia neo-adjuvante com radio-quimioterapia foram elegíveis 35 pacientes, tendo sido observada resposta completa tumoral em 11 casos (31%), e nove foram submetidos ao tratamento cirúrgico. Na comparação dos parâmetros leucocitários entre os pacientes com resposta completa (RC) e resposta incompleta (RI) foram observados os seguintes valores número total de leucócitos (média) RC 7390,9 × RI 7220,4 (p = 0,8); linfócitos totais RC 2103 × RI 1960,9 (p = 0,4); relação neutrófilo/linfócito RC 3,55 × RI 3,79 (p = 0,5). A dose radioterápica média foi de 49.1 Gy, sendo RC 47,3 × RI 50,0 (p = 0,06).

CONCLUSÃO:

Não foi possível demonstrar no presente estudo relação significativa entre resposta completa tumoral à terapia neo-adjuvante nos parâmetros analisados do perfil leucocitário. (AU)
