OBJECTIVES: To investigate the clinical-pathological characteristics and surgical prognosis of malignant tumor of pancreatic body and tail. METHODS: A retrospective study was accomplished on clinical manifestation, pathological behavior and postoperative survival in 106 patients with malignant tumor of pancreatic body and tail in single institution from Jan 1980 to Dec 2003, and compared these with 451 patients with malignant pancreatic cancer. RESULTS: There were significant differences in the following parameters (malignant tumor of the body and tail vs those of the head) between the two tumors: (1) the complaints of pain (0.74:41, chi(2) = 37.035, P < 0.01) and jaundice (0.04:0.75, chi(2) = 155.509, P < 0.01); (2) serum SGPT [(27.33 +/- 3.98) U/L: (118.60 +/- 4.59) U/L, F = 89.351, P < 0.01], total bilirubin [(1.46 +/- 0.46) mg/dl: (14.11 +/- 0.60) mg/dl, F = 105.341, P < 0.01] and albumin [(4.20 +/- 0.45) g/L: (3.91 +/- 0.03) g/L, F = 26.642, P < 0.001]; (3) CEA (0.40:0.24, chi(2) = 6.148, P = 0.046) and CA-19-9 positive rate (0.57:0.86, chi(2) = 24.132, P < 0.01); (4) the concomitant total metastasis (0.38:0.20, chi(2) = 14.266, P < 0.01), including liver metastasis (0.30:0.17, chi(2) = 9.003, P < 0.01). Postoperative median survival, resection of non-metastatic pancreatic body and tail cancer was longer than resection of metastatic disease significantly (15 vs 7 months,chi(2) = 21.63, P < 0.01), which the latter was the same as those who didn't remove (6 months,chi(2) = 0.22, P = 0.64). CONCLUSIONS: The predominant problem is distant metastasis (especially liver metastasis) in the malignant tumor of the body and tail of the pancreas in comparison with pancreatic head cancer. Resection of the body and tail could not increase postoperative survival if metastasis exists. The major way to improve the prognosis is to prevent and manage the distant metastasis.
