The observation
group was given 20 mg of leucogen before radiotherapy, three times a day, until the end of radiotherapy. The control group was given Midostaurin supplier 2∼5 μg/kg of recombinant human granulocyte colony-stimulating factor unless bone marrow suppression, once a day. The efficacy, incidence rate and occurrence time of bone marrow suppression and, the levels of white blood cells and platelets were compared. Results: There was no significant difference of response rate and disease control rate between the two groups (P > 0.05). The incidence rate of bone marrow suppression of observation group was 16.7 %, which was significantly lower than that of the control group (60.0 %, P < 0.05). No significant differences of the levels of white blood cells and platelets was found between before and after treatment in the observation group, but they were significantly decreased Selleck CCI-779 in the control group after
treatment (P < 0.05), which was significantly lower than those of the observation group after treatment (P < 0.05). Conclusion: Leucogen was effective in the prevention and treatment of bone marrow suppression induced by radiotherapy in patients with malignant tumor, it was worthy of being popularized in clinic.

Methods: Endoscopic snare papillectomy was performed in 34 patients with ampullary neoplasms (32 ampullary adenomas and 2 ampullary adenocarcinomas).
Thirteen patients had the microscopic remnant tissues (all adenomas) in the pathologic report after endoscopic en bloc resection. Eight patients were additionally treated by the APC at 5–7 days after endoscopic resection. In 5 patients, follow-up endoscopy with biopsies was performed after 3 months and then, in the presence of remnant tissues, the APC was introduced. All patients were followed by endoscopy with biopsies at 3 and 6 months and then, in the absence of recurrence, at yearly intervals. Results: There were no local recurrence in 8 patients received the immediate APC. Three of 5 follow-up patients experienced the local recurrence, which was successfully treated with repeated APC. Median follow-up periods was 13.4 months (reange: 3–37 months). Early complications occurred in 5 of 13 patients (38.5%, major bleeding, 1; perforation, 0; pancreatitis 3; cholecystitis, 1). Late complications occurred in 4 of 13 patients (30.8%, ampullary stricture, 1; bile duct stone, 2; pancreatitis, 1).
