Input: Of 6947 identified citations, 19 RCTs fulfilled the eligibility criteria. These trials enrolled 9650 participants. Trial registries' searches identified nine registered but unpublished trials, two of which were labeled as 'ongoing trials'. In all included RCTs, the intervention consisted of heparin (either unfractionated heparin or low molecular weight heparin). Overall, heparin appears to have no effect on mortality at 12 months (risk ratio (RR) 0.98; 95% confidence interval (CI) 0.93 to 1.03; risk difference (RD) 10 fewer per 1000; 95% CI 35 fewer to 15 more; moderate certainty of evidence) and mortality at 24 months (RR 0.99; 95% CI 0.96 to 1.01; RD 8 fewer per 1000; 95% CI 31 fewer to 8 more; moderate certainty of evidence). Heparin therapy reduces the risk of symptomatic VTE (RR 0.56; 95% CI 0.47 to 0.68; RD 30 fewer per 1000; 95% CI 36 fewer to 22 fewer; high certainty of evidence), while it increases in the risks of major bleeding (RR 1.30; 95% 0.94 to 1.79; RD 4 more per 1000; 95% CI 1 fewer to 11 more; moderate certainty of evidence) and minor bleeding (RR 1.70; 95% 1.13 to 2.55; RD 17 more per 1000; 95% CI 3 more to 37 more; high certainty of evidence). Results failed to confirm or to exclude a beneficial or detrimental effect of heparin on thrombocytopenia (RR 0.69; 95% CI 0.37 to 1.27; RD 33 fewer per 1000; 95% CI 66 fewer to 28 more; moderate certainty of evidence); quality of life (moderate certainty of evidence). Heparin appears to have no effect on mortality at 12 months and 24 months. It reduces symptomatic VTE and likely increases major and minor bleeding. Future research should further investigate the survival benefit of different types of anticoagulants in patients with different types and stages of cancer. The decision for a patient with cancer to start heparin therapy should balance the benefits and downsides, and should integrate the patient's values and preferences.

Output:

We searched the scientific literature for studies of anticoagulants in people with cancer. The evidence is current to 14 August 2017. We included 19 eligible trials. We selected 19 trials including 9650 participants with cancer. Most trials included participants with various types of cancer, especially small cell lung cancer, non-small cell lung cancer, and pancreatic cancer. All studies were conducted in the outpatient setting. The results suggest that the effect of injectable blood thinners on survival is uncertain, but if anything of small size. Also the results suggest that injectable blood thinners reduce the risk of blood clots by about half and possibly increase the risk of major bleeding and minor bleeding by 4 more per 1000 and 17 more per 1000, respectively. The effect on quality of life is uncertain. We judged the certainty of evidence to be high for symptomatic VTE and minor bleeding, and moderate for mortality, major bleeding and quality of life.
