Abstract:
Objective To study the clinicopathologic features of giant cell carcinoma of the pancreas(GCCP). Methods The clinicopathologic features of 19 pathologically diagnosed as GCCP were retrospecti- vely analyzed in detail, compared with 96 cases of common pancreatic carcinoma (PC). Results Tumors that occurred in the head of pancreas were found in 8 patients(42.1%), and those in the body or tail of pancreas in 11 patients(57.9%). The initial symptom is mainly characterized by abdominal pain (57.9%). Abdominal pain (73.7%), dyspepsia(63.2%) and weight loss(36.8%) were common symptoms when patients were diagnosed. Jaundices is not a common symptom in these patients. The abnormal rates of routine laboratory tests were dramatically lower than those in common PC. The assay of tumor markers between GCCP and common PC were approximately same. The sensitivity and accuracy of diagnosis by ultrasonography, spiral computed tomography and magnetic resonance imaging were high. The carcinomas grew so large that 9 patients ( 47.4%)were in stage Ⅳ, the rate of which was higher than that in common PC. Osteoid formation was found under microscopy in some patients, and the tumor cells differentiated poorly in most of patients. The overall 1-year survival rate was 17.6%, which was lower than that in common PC. Conclusions The clinicopathologic features of GCCP are different from those of common PC. Imaging tests may be combined with the assay of tumor markers simultaneously so as to diagnose GCCP as early as possible and thus the prognosis of GCCP patients could be improved.
