Preprints with The Lancet is part of SSRN´s First Look, a place where journals and other research experts identify content of interest prior to publication. These preprint papers are not peer-reviewed and are posted here as part of a 12-month trial. Authors have either opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet, or submitted directly via SSRN. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. These papers should not be used for clinical decision making or reporting of research to a lay audience without indicating that this is preliminary research that has not been peer-reviewed.

Abstract

Background: Whether cancer patients receive benefits from immunonutrition is unclear. We systematically reviewed the effect of immunonutrition versus standard nutrition on cancer patients.

Methods: The Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, EBSCOhost, and Web of Science were searched for studies reporting clinical outcomes comparing immunonutrition with standard nutrition from the date of database inception to May 28, 2018. We assessed the risk of bias using the Cochrane risk of bias tool and the quality of evidence using the grading of recommendations assessment, development, and evaluation approach.

Findings: In total, 79 randomized controlled trials with a total of 6970 adult cancer patients were included in the final pooled analysis. Compared with standard nutrition, immunonutrition was associated with a significantly lower risk of postoperative infection complications (RR 0*71 [95% CI 0*64 - 0*79], p<0*00001, I²=0), including a lower risk of wound infection (RR 0*72 [95% CI 0*60 - 0*87], p=0*0007, I²=0), respiratory tract infection (RR 0*70 [95% CI 0*59 - 0*84], p=0*0001, I²=0), and urinary tract infection (RR 0*69 [95% CI 0*51 - 0*964, p=0*02, I²=0), as well as a lower risk of anastomotic leakage (RR 0*70 [95% CI 0*53 - 0*91], p=0*009, I²=0) and a shorter hospital stay (RR -2*12 days [95% CI -2*72 to -1*52], p<0*00001, I2=82%). Among cancer patients who underwent surgery, no differences were found between the two groups with regard to sepsis (RR 0*75 [95% CI 0*45 - 1*25], p=0*27, I²=0) or all-cause mortality (RR 1*00 [95% CI 0*69-1*43], p=0*99, I²=0). Among chemoradiotherapy patients, no differences were found between the two groups with regard to oral mucositis (RR 0*95, 95% CI 0*86 to 1*04, I²=0), diarrhea (RR 0*96, 95% CI 0*81 to 1*13, I²=0) or all-cause mortality (RR 0*43, 95% CI 0*10 to 1*82, I²=0).

Interpretation: This systematic review and meta-analysis provides evidence that for surgical cancer patients, immunonutrition reduces postoperative infection complications (moderate quality) and shortens hospital stays (low quality) but does not reduce all-cause mortality (moderate quality); for chemoradiotherapy patients, immunonutrition is not superior to standard nutrition in improving oral mucositis (very low quality), diarrhea (low quality) or all-cause mortality (low quality).
