| Abstract | BACKGROUND AND OBJECTIVE: The incidence rates of colorectal cancer (CRC) are increasing in a number of different regions, and recent studies have indicated that addition of bevacizumab to CRC therapy is beneficial. To better understand the relative risk (RR) of adverse events associated with use of bevacizumab, we systematically reviewed published clinical trials that studied use of bevacizumab in treatment of patients affected by metastatic CRC (mCRC). METHODS: The National Library of Medicine PubMed, MEDLINE, Ovid, Cochrane Library and Chinese Biomedicine databases were searched. The RR and number needed to harm (NNH) values for major side effects with 95% confidence intervals (CIs) were calculated in a fixed-effects model and a random-effects model, where appropriate. RESULTS: Fifteen controlled trials totalling 6,937 patients were eligible for this analysis. Compared with the control group, the bevacizumab treatment group had a slightly higher risk of any severe adverse event (pooled RR 1.07 [95% CI 1.02-1.12]). The pooled risk difference was 5% [95% CI 2-9%], with an NNH of 20 treated patients. Analyses showed a statistically significantly higher risk of secondary endpoints, including the discovery that bevacizumab was associated with a threefold higher risk of hypertension (pooled RR 3.06 [95% CI 2.45-3.83]), a twofold higher risk of gastrointestinal haemorrhage/perforation and a lower risk of neutropenia (pooled RR 0.75 [95% CI 0.26-2.19]). CONCLUSION: Bevacizumab has efficacy in all treatment regimens for advanced CRC. However, our meta-analysis raises safety concerns regarding an increased risk of serious adverse events associated with use of bevacizumab among patients with mCRC. Our findings warrant cautious use of bevacizumab in clinical oncology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
