Abstract

Background

The negative impact of anastomotic leakage on cancer-specific survival and recurrence patterns has been recognized in colorectal cancer. In pancreatic cancer, pancreatic fistula (PF) is a serious morbidity, but its negative effect on long-term outcome remains to be elucidated. The aim of this study was to determine the impact of PF on pancreatic cancer recurrence.

Methods

The medical records of 184 patients with curative pancreatectomy for pancreatic cancer were reviewed. PF was scored on the basis of the International Study Group of Pancreatic Fistula classification. Overall and disease-free survivals and recurrence patterns were analyzed. Grade A PF was excluded because the negative effects can be negligible.

Results

PF occurred in 51 of the 184 patients (27.7%). The mortality related to PF was 0.5% (1 of 184). PF was an independent risk factor for peritoneal recurrence (hazard ratio 3.974; 95% confidence interval 1.345–11.737; P = 0.013). According to the analysis of disease-free survival in patients with peritoneal recurrence, time to recurrence was shorter and the survival rate was worse in patients with PF than in those without PF (5.6 vs. 8.2 months; 6-month survival, 40 vs. 71%; 1-year survival, 7 vs. 19%; P = 0.053). PF was an independent prognostic factor after multivariate analysis (hazard ratio 3.257; 95% confidence interval 1.201–8.828; P = 0.020).

Conclusions

PF was statistically significantly related to peritoneal recurrence, and patients with PF developed peritoneal recurrence earlier than those without PF. With regard to the development of peritoneal recurrence, PF may be considered to be a negative prognostic factor.
