Abstract

Objective The present study evaluated the profile of endoglin (CD105) and vascular endothelial growth factor (VEGF) based on staging and histopathological grading of colorectal cancer as well as their relationship with bevacizumab therapy.

Methods A total of 88 cases of colorectal adenocarcinoma were included in the present study. The levels of VEGF and CD105 protein were evaluated with enzyme-linked immunosorbent assay (ELISA).

Results There was a significant difference in the level of CD105 (p = 0.002) between metastases and non-metastases subjects, showing that CD105 was higher in metastases subjects (4.59 ng/ml). There was no significant difference in the level of VEGF based on the presence of metastasis (p = 0.625). There was a significant difference in the levels of CD105 (p = 0.038) and VEGF (p = 0.010) between the subjects who received chemotherapy and those who did not. The CD105 level was higher in the subjects who received chemotherapy (4.43 ng/ml); conversely, the level of VEGF was lower in subjects who received chemotherapy (543.65 pg/ml). There was a statistically significant difference in the levels of CD105 (p = 0.003) and VEGF (p = 0.002) between subjects who received bevacizumab therapy and subjects who did not. The levels of CD105 were higher in subjects who received bevacizumab therapy (5.11 ng/ml); in contrast, the level of VEGF was higher in subjects who did not receive bevacizumab therapy (645.92 pg/ml). There was a significant positive correlation between CD105 and VEGF in subjects who did not receive bevacizumab (p < 0.01).

Conclusion The results of this study support a hypothesis of “escape mechanism” in the failure of anti-angiogenesis therapy (anti-VEGF).

Resumo

Objetivo Este estudo avaliou o perfil da endoglina (CD105) e do fator de crescimento endotelial vascular (FCEV) com base no estadiamento e graduação histopatológica do câncer colorretal, assim como sua relação com a terapia com bevacizumabe.

Métodos No total, 88 casos de adenocarcinoma colorretal foram incluídos no presente estudo. Os níveis das proteínas FCEV e CD105 foram avaliados com ensaio imunoenzimático (ELISA, na sigla em inglês).

Resultados Houve uma diferença significativa no nível de CD105 (p = 0,002) entre indivíduos com metástases e sem metástases, que indicou que o nível de CD105 é mais alto em indivíduos com metástases (4,59 ng/ml). Não houve diferença significativa no nível de FCEV com base na presença de metástases (p = 0,625). Houve diferença significativa nos níveis de CD105 (p = 0,038) e de FCEV (p = 0,010) entre os indivíduos que receberam quimioterapia e os que não receberam. Encontrou-se um nível de CD105 mais alto nos indivíduos que submetidos a quimioterapia (4,43 ng/ml); Em contrapartida, encontrou-se um nível de FCEV mais baixo em indivíduos que submetidos a quimioterapia (543,65 pg/ml). Houve uma diferença estatisticamente significativa nos níveis de CD105 (p = 0,003) e de FCEV (p = 0,002) entre os indivíduos submetidos e não submetidos à terapia com bevacizumabe. Os níveis de CD105 foram mais elevados em indivíduos submetidos à terapia com bevacizumab (5,11 ng/ml); em contraste, observou-se um nível de FCEV mais alto em indivíduos que não foram submetidos à terapia com bevacizumabe (645,92 pg/ml). Houve uma correlação positiva significativa entre CD105 e FCEV em indivíduos que não receberam bevacizumabe (p < 0,01).

Conclusão Os resultados deste estudo corroboram a hipótese de “mecanismo de escape” na falha da terapia anti-angiogênica (anti-FCEV).
