title: Long-term survival in carcinoma of the biliary tract. Analysis of prognostic factors in 146 resections.
abstract: In 146 consecutive patients undergoing resection for carcinoma of the biliary tract, various tumor characteristics that affected long-term survival of the patients were studied. Patients with gallbladder carcinoma whose tumors had no serosal infiltration or vessel invasion were grossly papillary, or were papillary or well-differentiated adenocarcinoma histologically survived longer than those without these tumor characteristics. In upper-third lesions, patients whose tumors showed no serosal infiltration or vessel invasion, were grossly papillary, were papillary or well-differentiated adenocarcinoma histologically, or were treated with hepatic lobectomy had a higher chance of long-term survival. Patients with the middle-third lesions, whose tumors were grossly papillary or nodular or whose margins were tumor-free, were apt to survive longer. Long-term survival for patients with lower-third lesions was obtained most often in patients without lymph node metastasis or vessel invasion.
