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.

OBJECTIVETo compare quantitatively the enhanced thin CT section with pathologic findings in pulmonary carcinoma, pulmonary inflammatory pseudotumor (IPT) and pulmonary tuberculoma so as to demonstrate the relation of degree of enhancement and the vascular structure within the lesion with special emphasis on pulmonary carcinoma.
METHODSEnhanced thin CT sections were obtained in 35 cases with nodular or patchy lesions in the peripheral lung field which are difficult to differentiate clinically. There were pulmonary carcinoma 21, inflammatory pseudotumor 7 and tuberculoma 7. The number of small vessels (inner diameter 0.02 approximately 0.1 mm), relatively large vessels (inner diameter > 0.1 mm) and their vascular bed areas were analyzed by computed image analyzing system. The relation between CT average attenuation and the number of vessels or the vascular bed areas were statistically evaluated.
RESULTS1. The differences of average attenuation in carcinoma, inflammatory pseudotumor and tuberculoma were statistically significant (P < 0.05). 2. The differences in number of small vessels, relatively large vessels and vascular bed areas among these three types of lesion were also significant (P < 0.05). 3. A positive correlation was found in the average CT affenuation of lung carcinoma and its number of small vessels and relatively large vessels and 4. A positive correlation was found between the average CT attenuation in these three lesions and the relatively large vessels, total vascular amount and vascular bed areas.
CONCLUSIONS1. The average degree of attenuation, being divided into four degrees, is of practical value in the differentiation of lung carcinoma, inflammatory pseudotumor and tuberculoma. 2. The average CT attenuation of lung carcinoma, inflammatory pseudotumor and tuberculoma is in direct proportion to the number of vessels and vessel bed areas and 3. The characteristic CT enhancement in lung carcinoma reflexes the condition of vessels and blood supply within the tumor.
