THE ROLE OF PREOPERATIVE STAGING FOR PANCREATIC CANCER

Despite the poor prognosis of pancreatic carcinoma patients, surgical resection remains the only potentially curative treatment. As it has been demonstrated that extended radical surgery does not lead to a better prognosis, accurate staging to select those patients who may benefit from resection is essential. According to the report of a national survey of pancreatic cancer in 1997, patients with S0 or S1, RP0 or RP1, and N0 or N1 disease have longer survival periods compared with patients with S2, RP2, and N2 disease. Therefore patients classified as Stage I, Stage II, or Stage III are recognized as candidates for surgical resection. Patients classified as Stage IVb because of positive P factor or positive H factor are selected for conservative treatment such as chemotherapy and irradiation. It remains to be clarified whether patients classified as Stage IVa should undergo surgical resection or not. Future prospective randomized studies of patients with Stage IVa disease will reveal whether surgical resection or chemoradiation is effective. Helical CT is useful to evaluate S and RP factors for definitive preoperative staging. CT-AP can reveal occult metastases to the liver. These preoperative evaluations should be evaluated along with histological findings.
