BACKGROUND: Neoadjuvant treatment frequently is performed in unresectable/borderline resectable pancreatic cancer. The aim of this study was to retrospectively compare postoperative outcomes and survival of patients who underwent pancreatectomy after neoadjuvant treatment for locally advanced/borderline resectable pancreatic cancer (neoadjuvant treatment group) with those of patients with resectable disease who underwent upfront surgery.
METHODS: Between 2000 and 2008, there were 403 patients who underwent pancreatic cancer resection, 41 (10.1%) patients after neoadjuvant treatment for initially unresectable tumors and 362 (89.9%) patients had upfront surgery. Univariate and multivariable analyses were performed.
RESULTS: Mortality/morbidity rates were similar in the 2 groups. Nodal metastases were significantly lower in the neoadjuvant treatment group (31.7% vs 86.2%; P<.001). A complete pathologic response was observed in 13.6% after neoadjuvant treatment. Median disease-specific survival from resection was 35 and 27 months in the neoadjuvant treatment and upfront groups, respectively (P = .74). In the neoadjuvant treatment group survival rates were similar in N0/N1 patients.
CONCLUSIONS: Postoperative mortality and morbidity do not significantly increase after neoadjuvant treatment. Neoadjuvant treatment in locally advanced pancreatic cancer can lead to an objective pathologic response, but this does not significantly improve survival after resection.
