ABSTRACT

INTRODUCTION:

the standard treatment for locally advanced extra-peritoneal rectal adenocarcinoma, consists of neoadjuvant treatment with radiotherapy and chemotherapy followed by total mesorectal excision.

OBJECTIVE:

evaluate, retrospectively, the patients submitted to neoadjuvant therapy and surgery that presents with total remission of the lesion in the anatomopathological examination.

METHODS:

between 2000 and 2010, 212 patients underwent surgery at the Coloproctology Unit at DMAD at FCM-UNICAMP. They were grouped as rectosigmoidectomy and colorectal anastomosis (n = 54), rectosigmoidectomy with coloanal anastomosis (n = 41), 114 abdominoperineal resection of the rectum (n = 114) and other (n = 3).

RESULTS:

thirty (14.2%) patients (mean age 57.6 years; 60% males) showed complete remission of the rectal lesion. 4 (13.3%) had compromised lymph nodes and/or lymphatic invasion At follow-up (mean 51.9 months), 4 (13.3%) presented with local recurrence (one patient) or distant metastases (two patients had liver metastasis, one had liver and lung, and one had bone metastasis). The mean survival was 86.7%.

CONCLUSION:

patients with a complete tumor response show ed an increased survival rate, however, the same patients without evidence of residual tumors could develop local recurrence or distant metastases on a later follow-up. (AU)
RESUMO

INTRODUÇÃO:

o tratamento padrão do adenocarcinoma de reto extra-peritoneal localmente avançado consiste de neoadjuvância com radio e quimioterapia, seguida de cirurgia com excisão total do mesorreto.

OBJETIVO:

avaliar, retrospectivamente, os pacientes submetidos à neoadjuvância e cirurgia, que apresentaram remissão completa da lesão no reto no exame anatomopatológico.

MÉTODOS:

foram avaliados 212 doentes, operados no Serviço de Coloproctologia da DMAD da FCM-Unicamp, entre 2000 e 2010. As cirurgias realizadas foram retossigmoidectomia e anastomose colorretal (n = 54), retossigmoidectomia com anastomose coloanal (n = 41), amputação abdominoperineal do reto (n = 114) e outras (n = 3).

RESULTADOS:

trinta (14,2%) pacientes (média de idade de 57,6 anos; 60% do sexo masculino) apresentaram remissão tumoral completa no reto; destes, 4 (13,3%) tinham acometimento linfonodal e/ou invasão linfática. No seguimento pós-operatório (médio de 51,9 meses), 4 (13,3%) apresentaram recidiva local (um doente) ou metástases à distância (dois doentes com metástases hepáticas, uma hepática e pulmonar, e um outro metástase óssea). A sobrevida média do grupo foi de 86,7%.

CONCLUSÃO:

os pacientes com resposta tumoral completa no reto apresentaram elevada taxa de sobrevida, mas mesmo doentes sem evidência de tumor residual, podem apresentar recidiva local ou metástases à distância no seguimento tardio. (AU)
