ABSTRACT
BACKGROUND:
Preoperative chemo- or chemoradiotherapy is recommended for borderline-resectable pancreatic cancer. The aim of this study was to determine the impact of preoperative therapy on surgical complications in patients with resected pancreatic cancer.METHODS:
This systematic review and meta-analysis included studies reporting on the rate of surgical complications after preoperative chemo- or chemoradiotherapy versus immediate surgery in pancreatic cancer patients. The primary endpoint was the rate of grade B/C POPF. Pooled odds ratios were calculated using random-effects models.RESULTS:
Forty-one comparative studies including 25,389 patients were included. Vascular resections were more often performed after preoperative therapy (29.4% vs. 15.7%, p < 0.001). Preoperative therapy was associated with a lower rate of grade B/C POPF as compared to immediate surgery (pooled OR 0.47, 95%CI 0.38-0.58). This reduction was mostly obtained by preoperative chemoradiotherapy (OR 0.46, 95%CI 0.29-0.73), but not by preoperative chemotherapy alone (OR 0.83, 95%CI 0.59-1.16). No difference was demonstrated for major morbidity, mortality, postpancreatectomy haemorrhage, delayed gastric emptying and overall morbidity.CONCLUSION:
Preoperative chemo- and chemoradiotherapy in patients with pancreatic cancer appears to be safe with respect to POPF and other surgical complications as compared to immediate surgery. The reduced rate of POPF appears to be attributable to preoperative chemoradiation.
