Coadjuvant anti-VEGF A therapy improves survival in patients with colorectal cancer with liver metastasis: a systematic review
| Resumo: | Background: the presence of liver metastasis in colorectal cancer (CRC) remains one of the most significant prognostic factors. Objective: systematically review the results of studies evaluating the benefit of adding bevacizumab to a normal chemotherapy regime in the survival of patients with colorectal-cancer liver metastasis (CRLM). Search methods: Pubmed and Google Scholar databases were searched for eligible articles (from inception up to the 2 April 2019). Inclusion criteria: studies including patients with CRLM receiving anti-vascular endothelial growth factor (VEGF; bevacizumab) as treatment, overall survival as an outcome; regarding language restrictions, only articles in English were accepted. Main results: Eleven studies met the inclusion criteria. In 73% of these cases, chemotherapy with bevacizumab was an effective treatment modality for treating CRLM, and its administration significantly extended both overall survival (OS) and/or progression-free survival (PFS). Nevertheless, three articles showed no influence on survival rates of bevacizumab-associated chemotherapy. Author conclusions: It is necessary to standardize methodologies that aim to evaluate the impact of bevacizumab administration on the survival of patients with CRLM. Furthermore, follow-up time and the cause of a patient’s death should be recorded, specified, and cleared in order to better calculate the survival rate and provide a comparison between the produced literature. |
