    Abstract:
    OBJECTIVE: To analyze the clinical and pathological features in order to investigate appropriate way of diagnosis and treatment for non-functional islet cell tumors of the pancreas (NFICT). METHODS: The data and experience of surgically treated 43 patients with pathologically confirmed NFICT over the last 30 years were retrospectively reviewed. The survival rate was estimated using Kaplan-Meier method and the potential risk factors affecting survival were compared with Log rank test. RESULTS: There were 7 males and 36 females in this series with a mean age of 31.6 years ranged from 8 to 67 years. Twenty-eight patients were diagnosed as having non-functional islet cell carcinomas of the pancreas (NFICC) and 15 patients benign islet cell tumors. The most common symptoms in NFICT were abdominal pain 55.8%, nausea and/or vomiting (32.6%), fatigue (25.6%) and abdominal mass (23.3%). Preoperatively, all of those were found to have a mass in their pancrease by ultrasonic and computed tomography examination, with 21 in the head, 10 in the body and 6 in the tail of the pancreas. Multicemtric tumor were found in one patient. Thirty-nine of these 43 patients (90.7%) underwent surgical resection, with a curative resection in 30 (69.8%) and palliative in 9 (20.9%). The resectability and curative resection rate in 28 patients with nonfunctioning islet cell carcinomas of the pancreas was 78.6% and 60.7%, respectively. None of the 15 patients with benign nonfunctioning islet cell tumor of the pancreas died of this disease. While the overall cumulative 5- and 10-year survival rate in 28 patients with non-functional islet cell carcinomas of the pancreas was only 58.1% and 29.0%, respectively. Curative resection, female, younger than 30 years old and mass diameter < 10 cm were found to be positive prognostic factors. But multivariate Cox regression analysis indicated that radical resection was the only independent prognostic factor (P = 0.007). CONCLUSION: Nonfunctioning islet cell tumor of the pancreas is frequently found in young female. Surgical resection, especially curative resection can achieve satisfactory long-term survival.
