This study reviews the literature to assess whether there is evidence to justify modern phase Ⅱ studies of neoadjuvant chemoradiotherapy prior to resection of PH-CCA.Data sources: A systematic review of the literature for reports of patients undergoing resection of PH- CCA after neoadjuvant chemoradiotherapy was performed using MEDLINE and EMBASE databases for the period between 1990 and 2019. The keywords and MeSH headings "hilar cholangiocarcinoma", "Klatskin", "chemoradiotherapy" and "chemotherapy" were used. Data were extracted on demographic profile, dis- ease staging, chemoradiotherapy protocols, complications and outcome. Risks of bias were assessed using Cochrane methodology. Results: There were seven reports on this topic, with median recruitment period of 14 (range 4–31) years. The total number of patients in these studies was 87. Interval from completion of neoadjuvant treatment to surgery varied from 3 days to 6 months. Resection was by hepatectomy with three studies reporting an R0 rate of 100%, 24% and 63%, respectively. Three studies reported histopathological evidence of prior treatment response. There were two treatment related deaths at 90 days. Median survival was 19 (95% CI: 9.9–28) months and 5-year survival 20%. Conclusions: There are potential benefits of treatment on both R0 rate and complete response in resected specimens. Scientific equipoise exists in relation to neoadjuvant chemoradiotherapy for PH-CCA.展开更多
