ABSTRACT
OBJECTIVE: to evaluate the effect of perioperative administration of symbiotics on the incidence of surgical wound infection in patients undergoing surgery for colorectal cancer. METHODS: We conducted a randomized clinical trial with colorectal cancer patients undergoing elective surgery, randomly assigned to receive symbiotics or placebo for five days prior to the surgical procedure and for 14 days after surgery. We studied 91 patients, 49 in the symbiotics group (Lactobacillus acidophilus 108 to 109 CFU, Lactobacillus rhamnosus 108 to 109 CFU, Lactobacillus casei 108 to 109 CFU, Bifi dobacterium 108 to 109 CFU and fructo-oligosaccharide (FOS) 6g) and 42 in the placebo group. RESULTS: surgical site infection occurred in one (2%) patient in the symbiotics group and in nine (21.4%) patients in the control group (p=0.002). There were three cases of intraabdominal abscess and four cases of pneumonia in the control group, whereas we observed no infections in patients receiving symbiotics (p=0.001). CONCLUSION: the perioperative administration of symbiotics significantly reduced postoperative infection rates in patients with colorectal cancer. Additional studies are needed to confirm the role of symbiotics in the surgical treatment of colorectal cancer.

RESUMO Objetivo: avaliar o efeito da administração perioperatória de simbióticos na incidência de infecção de ferida operatória em pacientes operados por câncer colorretal. Métodos: ensaio clínico randomizado de pacientes com câncer colorretal submetidos à cirurgia eletiva e aleatoriamente designados para receberem simbióticos ou placebo por cinco dias antes do procedimento cirúrgico e por 14 dias após a cirurgia. Noventa e um pacientes foram estudados: 49 para o grupo de simbióticos (Lactobacillus acidophilus 108 a 109 UFC, Lactobacillus rhamnosus 108 a 109 UFC, Lactobacillus casei 108 a 109 UFC, Bifi dobacterium 108 a 109 UFC e fruto-oligosacarídeos (FOS) 6g) e 42 para o grupo placebo. Resultados: infecção de sítio cirúrgico ocorreu em um (2%) paciente no grupo de simbióticos e em nove (21,4%) pacientes no grupo controle (p=0,002). Três casos de abscesso intra-abdominal e quatro casos de pneumonia foram diagnosticados no grupo controle, enquanto não foram observadas tais infecções em pacientes que receberam simbióticos (p=0,001). Conclusão: a administração perioperatória de simbióticos reduziu significativamente as taxas de infecção pós-operatória em pacientes com câncer colorretal. Estudos adicionais são necessários para confirmar o papel dos simbióticos no tratamento cirúrgico do câncer colorretal.

BACKGROUND: The possible involvement of inflammation on colorectal carcinogenesis has potential prognostic, preventive and therapeutic implications. We investigated immunohistochemically whether C-reactive protein is expressed in human primary rectal adenocarcinoma and assessed its relationship with clinicopathological findings. METHODS: Ninety-one rectal cancer samples and 22 normal control samples were immunohistochemically analysed. RESULTS: Cell accumulation of C-reactive protein was observed in 65 (71%) out of 91 patients with rectal adenocarcinoma and in all 22 control cases (p < 0.01). No significant difference was observed regarding to clinicopathological features or survival rates, but a linear correlation between the positivity proportion of C-reactive protein and Dukes-Turnbull stage (p = 0.005) was observed. CONCLUSIONS: These data suggest that C-reactive protein might play a role in rectal carcinogenesis, but seems not to affect prognosis. Additional studies are warranted in larger population samples.
ABSTRACT
A disseminação metastática endotraqueal e endobrônquica do câncer de cólon é um evento raro. Os autores relatam o caso de um paciente com manifestação aguda de doença metastática endotraqueal e endobrônquica, 10 anos após o tratamento do tumor primário.
