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.
