Study summary

Pancreatic cancer is a disease with an extremely poor prognosis. Such poor results are largely due to a high incidence of local or peritoneal recurrence even after curative R0 resection. If occult microscopic metastasis or residual cancer could be predicted correctly and identify the high risk of peritoneal recurrence, we may have chance to treat these patients by different multimodal locoregional or adjuvant therapy to improve the treatment outcome.

Read the detailed description

The purpose of this study has three specific aims: (1) to determine the relationship between peritoneal washing cytology (PWC) results and clinicopathologic parameters of pancreatic cancers, (2) to identify the predictive value of PWC and postoperative drainage cytology on the peritoneal recurrence or outcomes, (3) to dissect the molecular mechanism of peritoneal recurrence, especially on the PWC-inducing peritoneal seeding process.
