Objective To evaluate the efficacy and side effects of whole body γ/-knife in patients with limited pancreatic carcinoma. Methods 111 patients with limited pancreatic carcinoma treated with the Stereotactie Gamma Ray Whole-Body Therapeutic System (Whole Body T-knife) were retrospectively an-alyzed. Patients were supine, fixed with a stereotactic body frame and vacuum bag, and then simulated by low-speed computed tomography. GTV, CTV and PTV were defined on the contrast-enhanced CT scans. It was required that 50% isedose line covered 100% of PTV and 70% isedose line covered more than 80% of GTV. The prescription dose was defined as 50% isodose. All patients were treated 5 fractions per week. The fractionated dose was 3-4 Gy for pancreatic head carcinoma, and 4-5 Gy for pancreatic body/tail carcino-ma. Irradiation of 40-51 Gy and 60-70 Gy were delivered to PTV and GTV margins, respectively. Re-suits The complete response rate, partial response rate and overall response rate of the primary tumors were 29.7%, 42.3% and 72.1%, respectively. The follow-up rate was 95.5%. The number of patients fol-lowed-up at 1-,2- and 3-year was 105,89 and 60. The 1-, 2- and 3-year overall survival rates were 49.3%,24.5% and 18.1%. For patients with stage Ⅰ/Ⅱ disease,the number of patients followed-up at 1-,2-,3-,4-and 5-year was 55,44,29,16 and 11 ;The 1-, 2-, 3-,4- and 5-year overall survival rates were 68%,34%, 30%, 21% and 17%, respectively. For patients with stage Ⅲ disease,the number of patients fol-lowed-up at 1-,2- and 3-year was 50,45 and 31 ;The 1-, 2- and 3-year overall survival rates were 28%,14% and 4%, respectively (χ~2=16.67, P=0.000). The acute side effects including nausea, vomiting and diarrhea were 71.2% of RTOG grade 1 -2 and 3.6% of RTOG grade 3. No treatment delay occurred.Conclusions With fractionated dose of 3-5 Gy,5 fractions per week and 40-51 Gy as total dose to PTV,whole body γ-knife is safe and effective to treat limited pancreatic carcinoma. The local control and overall survival could be improved.

BACKGROUND: Recent studies indicate that bone marrow messenchymal stem cells (MSCs) can repairinjured myocardium and improve cardiac functions. However, there are still no effective non-invasive methods to detect ventricular wall motion, survival status of transplanted cells, and microcirculation improvement after MSCsimplantation. OBJECTIVE: To detect the effects of MSCs implantation on the cardiac function of ischemic myoeardium and investigate changes of tissue acoustics characteristics by using integrated backscatter (IBS) and Doppler tissue imaging (DT1). DESIGN, TIME AND SETTING: Completely randomized grouping design, and randomized controlled study, which was carried out in the Department of Cardiology, Renmin Hospital of Wuhan University from December 2004 to June 2005 (important laboratory of 211 government). MATERIALS: Forty-eight male rabbits with irrespective of gender were used for study. Anti-troponin T (TnT) antibody was provided by Maxim Company, USA; anti-bromodeoxyuridine (BrdU) antibody by Sigma Company, USA; Sonos 5500 echocardiography by HP Company, USA.METHODS: Forty-eight rabbits were randomly divided into model group and implantation group. Model of myocardium infarction was created in rabbits by left anterior descending coronary artery (LAD) ligation. Three days after modeling, autologous bone marrow MSCs were injected into crossed myocardium between infarction and non-infarction regions based on 5 injected points.MAIN OUTCOME MEASURES: Indicators including ventricular size, ventricular wall thickness, and ejection fraction (EF) in the left ventricle (LV) were measured with routine echocardiography one day before myocardial infarction, two weeks after myocardial infarction, and four weeks after implantation. IBS and DTI might detect the anterior backscatter parameters (AII, or IB) and ventricular wall motion parameters (PPI, or CVIB) to calculate the average backscatter scores and backscatter cycle changes. DTI was used to measure peak systolic flow velocity (VS), peak early diastolic flow velocity (VE), and peak late diastolic flow velocity (VA) of the middle and basal segments of the anterior wall of left ventricle. Finally, animals were sacrificed by anesthesia, and myocardial infarction region was stained with 5-Brdu immunohistochemical staining, and anti-TnT staining. RESULTS: Twelve rabbits were excluded because of death after operation.① Echocardiography: Imaging of 36 rabbits were clear in 1 day before myocardial infarction, 2 weeks after myocardial infarction, and 4 weeks after implantation. The sizes and systolic function of LV in 36 rabbits were normal before operation. Two weeks after operation, the sizes of LV became larger, the anterior wall of LV became thinner, and systolic range became weaker even disappeared. EF, CVIB, Vs, and Ve were lower (P < 0.05) and All was higher in both groups than pre-operation (P < 0.05). Four weeks after implantation, compared with control group, left ventricular diastolic diameter (LVDd) was smaller and systolic range became larger, All descended. EF, Vs, Ve and CVIB increased (P < 0.05).② Myocardial immunohistochemical detection: Numerous of Brdu-labeled positive cells were scattered, and anti-TnT was positive, which clearly showed horizontal stria of myocardium. However, normal myocardium was negative. CONCLUSION: Bone marrow MSCs after implantation can survive in ischemic myocardium and improve cardiac function. IBS and DTI can real-timely and exactly detect functional changes of infarction myocardium after bone marrow MSCs implantation.
