The objective of this article was to review published, recruiting or planned randomized controlled trials (RCTs) evaluating CRS and HIPEC versus standard of care. Comparator was systemic chemotherapy and\/or CRS alone.<\/jats:p><\/jats:sec><jats:sec id=\"j_pp-2016-0027_s_006_w2aab3b8c25b1b7b1aab1c15b2Aa\"><jats:title>Content<\/jats:title><jats:p>Systematic review according to PRISMA guidelines. Electronic searches for published RCT using PubMed (from 1980 to November 2016) and for ongoing RCT in the United States and European clinical databases (until November 2016). Current update on ongoing trials from the 10th PSOGI meeting in November 2016 in Washington DC. Fourteen RCTs on CRS and HIPEC were excluded for various reasons.<\/jats:p><\/jats:sec><jats:sec id=\"j_pp-2016-0027_s_007_w2aab3b8c25b1b7b1aab1c15b3Aa\"><jats:title>Summary<\/jats:title><jats:p>Thirty-eight trials designed for randomizing 7,303 patients were identified: 11 in colorectal cancer (6 for prevention of PM, n=1,107 patients; 5 for therapy, n=781), 10 in ovarian cancer (5 in frontline therapy, n=438 patients; 5 for treating recurrence, n=1,062) and 17 in gastric cancer (14 for prevention of PM, n=3,659 patients; 3 for therapy, n=256). Results of 9 RCTs have been published: 1 in colorectal cancer (105 patients), 1 in ovarian cancer (130 patients) and 7 in gastric cancer (together 669 patients). Five RCTs have completed recruitment and follow-up is ongoing. There is a clear trend in recent trial design from therapeutic to preventive indications.<\/jats:p><\/jats:sec><jats:sec id=\"j_pp-2016-0027_s_008_w2aab3b8c25b1b7b1aab1c15b4Aa\"><jats:title>Outlook<\/jats:title><jats:p>The number of published RCT evaluating CRS and HIPEC in prevention or therapy of PM is relatively small. There is some evidence that CRS and HIPEC improve survival in recurrent colorectal origin, evidence in ovarian and gastric cancer remains debated. A large number of studies is ongoing that might deliver additional evidence. Trial design and interpretation of results remain difficult because of multiple methodological challenges.<\/jats:p><\/jats:sec>","DOI":"10.1515\/pp-2016-0027","type":"journal-article","created":{"date-parts":[[2017,1,14]],"date-time":"2017-01-14T10:01:50Z","timestamp":1484388110000},"page":"169-182","source":"Crossref","is-referenced-by-count":18,"title":["Randomized controlled trials evaluating cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in prevention and therapy of peritoneal metastasis: a systematic review"],"prefix":"10.1515","volume":"1","author":[{"given":"Clarisse","family":"Eveno","sequence":"first","affiliation":[{"name":"1Paris Diderot University, Sorbonne Paris Cit\u00e9, CART, INSERM U965, Paris, France"},{"name":"2Surgical Oncologic & Digestive Unit, Lariboisi\u00e8re Hospital, AP-HP, Paris Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Pocard","sequence":"additional","affiliation":[{"name":"1Paris Diderot University, Sorbonne Paris Cit\u00e9, CART, INSERM U965, Paris, France"},{"name":"2Surgical Oncologic & Digestive Unit, Lariboisi\u00e8re Hospital, AP-HP, Paris Cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref771","first-page":"1527","article-title":"Intraperitoneal hyperthermic chemotherapy as treatment of peritoneal carcinomatosis of colorectal cancer","volume":"22","year":"2004","journal-title":"Letter to the editor.
