Gastric cancer, Peritoneal washing cytology, Staging, Prognosis


Objective: To present an estimate of the prevalance of positive peritoneal washing cytology (+PWC) in gastric cancer and to identify risk facctors for +PWC.

Method: Medical charts of 54 patients with gastric cancer who underwent D2 gastrectomy between January 2006 and December 2013 were reviewed.

Results: A total of 12 patients (22%) had +PWC. Factor significantly associated with +PWC include serosal invasion, nodal metastasis and poorly differentiated histology. All patients with +PWC developed peritoneal recurrence. The 5-year overall survival rate for patients with +PWC and -PWC were 0% and 83%, respectively.

Conclusion: Gastric cancer with +PWC should be considered as stage IV diseases. PWC should be included in the staging of gastric cancer.
