Preoperative serum CA19-9 predicts postoperative pancreatic fistula in PDAC patients: retrospective analysis at a single institution.

ABSTRACT:

Background

Postoperative pancreatic fistula (POPF) is a critical complication of pancreatectomy in patients with pancreatic ductal adenocarcinoma (PDAC). Recent papers reported that serum carbohydrate antigen (CA)19-9 levels predicted long-term prognosis. We investigated whether preoperative serum CA19-9 levels were associated with POPF in PDAC patients.

Methods

This cohort study was conducted at a single institution retrospectively. Clinicopathologic features were determined using medical records.

Results

Among of 196 consecutive patients who underwent pancreatectomy against PDAC, 180 patients whose CA19-9 levels were above the measurement sensitivity, were registered in this study. The patients consisted of 122 patients who underwent pancreaticoduodenectomy and 58 patients who underwent distal pancreatectomy. Several clinicopathological factors, including CA 19-9 level, as well as surgical factors were determined retrospectively based on the medical records. Patients with high CA19-9 levels had a significantly higher incidence of POPF than those with low levels (43.9 vs. 13.0%, P < 0.0001). The receiver operating characteristic curves calculated that the cutoff CA19-9 value to predict POPF was 428 U/mL. CA19-9, BMI, curability, and histology were statistically significant risk factors for POPF by univariate analysis. Multivariate analysis showed that CA19-9 and BMI levels were statistically significant independent risk factors for POPF. CA19-9 levels were correlated with both histology and curability. Disease free survival and overall survival of patients with higher levels of CA19-9 were significantly shorter than that of patients with lower levels of preoperative serum CA19-9.

Conclusions

In patients undergoing pancreatectomy for PDAC, higher preoperative CA19-9 levels are a significant predictor for POPF.

Project description:ObjectiveWhether preoperative serum carbohydrate antigen 19-9 (CA19-9) is an independent prognostic factor and there are interactions of serum CA19-9 with carcinoembryonic antigen (CEA) on the risk of recurrence in colorectal cancer (CRC) patients are still not clarified.MethodsConsecutive patients with CRC who underwent curative resection for stage II-III colorectal adenocarcinoma at five hospitals were collected. Based on Cox models, associations of preoperative CA19-9 with recurrence-free survival (RFS) and overall survival (OS) were evaluated in patients with or without elevated CEA, and interactions between CEA and CA19-9 were also calculated. Restricted cubic spline (RCS) curves were used to evaluate the associations between preoperative CA19-9 and CRC outcomes on a continuous scale.ResultsA total of 5048 patients (3029 [60.0%] men; median [interquartile range, IQR] age, 61.0 [51.0, 68.0] years; median [IQR] follow-up duration 46.8 [36.5-62.4] months) were included. The risk of recurrence increased with the elevated level of preoperative CA19-9, with the slope steeper in patients with normal CEA than those with elevated CEA. Worse RFS was observed for elevated preoperative CA19-9 (> 37 U/mL) (n = 738) versus normal preoperative CA19-9 (≤ 37 U/mL) (n = 4310) (3-year RFS rate: 59.4% versus 78.0%; unadjusted hazard ratio [HR]: 2.02; 95% confidence interval [CI]:1.79 to 2.28), and significant interaction was found between CA19-9 and CEA (P for interaction = 0.001). Increased risk and interaction with CEA were also observed for OS. In the Cox multivariable analysis, elevated CA19-9 was associated with shorter RFS and OS regardless of preoperative CEA level, even after adjustment for other prognostic factors (HR: 2.08, 95% CI:1.75 to 2.47; HR: 2.25, 95% CI:1.80 to 2.81). Subgroup analyses and sensitivity analyses yielded largely similar results. These associations were maintained in patients with stage II disease (n = 2724).ConclusionsPreoperative CA19-9 is an independent prognostic factor in CRC patients. Preoperative CA19-9 can be clinically used as a routine biomarker for CRC patients, especially with preoperative normal serum CEA.
