PURPOSE: Although the same distal pancreatectomy (DP) is performed regardless of the location of left-sided pancreatic ductal adenocarcinoma (PDAC), the clinicopathological features may differ depending on the tumor location. The present study investigated the relationship between the tumor location and clinicopathological features in patients with left-sided PDAC.
METHODS: The records of 59 patients who underwent DP for PDAC were enrolled. The relationship between the tumor location and clinicopathological features was investigated. The tumor location was classified into three groups according to the 7th AJCC/UICC TNM classification: body (Pb), body and tail (Pbt), and tail (Pt).
RESULTS: Tumors were located at the Pb in 26 patients, Pbt in 15, and Pt in 18. There was no metastasis to the lymph nodes around the common hepatic artery in Pt. The rate of peritoneal dissemination in the Pt was higher than that in the Pb (P = 0.034) or Pbt (P = 0.002). There were no significant differences in the overall survival among the three groups.
CONCLUSION: There was no metastasis to the lymph nodes around the common hepatic artery, and peritoneal dissemination was the most common site of recurrence in Pt tumors.
