ABSTRACT
ABSTRACT

BACKGROUND:

Colorectal cancer is one of the major causes of death worldwide. Many studies have been done on the biology of its formation as well as its treatment in recent years. One of the factors involved in the formation or treatment of this malignancy can be attributed to the microbial flora in the intestine.

OBJECTIVE:

This study investigate the potential preventive effect of Lactobacillus acidophilus and Lactobacillus plantarum in patients with polyps or colorectal cancer (CRC).

METHODS:

A total of 77 samples were selected in the form of three groups including individuals suffering from CRC, polyps and healthy subjects. Genomic DNA of fecal specimens and standard strains were extracted and amplified employing primers targeting of the 16S rRNA gene for initial detection. Absolute Real Time PCR quantification was used to determine the copy of the bacterial expression per gram of feces.

RESULTS:

No significant difference were observed between age and gender in the mentioned groups (P=0.06). The average copy number of Lactobacillus acidophilus shows Significant difference between the healthy group and those with polyps (P<0.0001), the healthy group and those with colorectal cancer (P<0.0001), as well as those with polyps and the colorectal cancer patients (P<0.0001).

CONCLUSION:

These results may indicate that taking Lactobacillus acidophilus in people with a family history of CRC and people with polyps may be a way of preventing, treating or reducing the severity of CRC.
RESUMO
RESUMO

CONTEXTO:

O câncer colorretal é uma das principais causas de morte em todo o mundo. Muitos estudos têm sido feitos sobre a biologia de sua formação, bem como o seu tratamento nos últimos anos. Um dos fatores envolvidos na formação ou no tratamento desta malignidade pode ser atribuído à flora microbiana no intestino.

OBJETIVO:

Este estudo investigou o potencial efeito preventivo de Lactobacillus acidophilus e Lactobacillus plantarum em pacientes com pólipos ou câncer colorretal (CCR).

MÉTODOS:

Um total de 77 amostras foram selecionadas e três grupos foram formados, a saber, indivíduos portadores de CCR, pólipos e indivíduos saudáveis. O DNA genomico de espécimes fecais e de amostras padrão foi extraído e amplificado empregando primers que focalizaram o gene do rRNA 16S para a deteção inicial. A quantificação do PCR em tempo real absoluto foi utilizada para determinar a cópia da expressão bacteriana por grama de fezes.

RESULTADOS:

Não foram observadas diferenças significativas entre idade e sexo nos grupos citados (P=0,06). O número médio de cópias de Lactobacillus acidophilus mostra diferença significativa entre o grupo saudável e aqueles com pólipos (P<0,0001), o grupo saudável e aqueles com câncer colorretal (P<0,0001), bem como aqueles com pólipos e câncer colorretal pacientes (P<0,0001).

CONCLUSÃO:

Estes resultados podem indicar que a ingestão de Lactobacillus acidophilus em pessoas com antecedentes familiares de CCR e pessoas com pólipos pode ser uma forma de prevenir, tratar ou reduzir a gravidade da CCR.
