作者对70例胰腺癌作术中照射,其中Ⅰ期1例,Ⅱ期13例,Ⅲ期44例及Ⅳ期12例。术中照射采用电子回旋加速器10～20MeV,线量15～40Gy(平均23.5Gy)。按治疗时间不同,分3组。前期(1976.4～1979.12)19例,中期(1980.1～1983.3)19例,后期(1983.4～1987.6)32例。治疗期间平均存活期前期为4个月,中期6个月及后期11.5个月。前后期可见有意义差别(P<0.01)。
The authors performed intraoperative irradiation on 70 cases of pancreatic cancer, including 1 in stage I, 13 in stage II, 44 in stage III, and 12 in stage IV. Intraoperative irradiation was performed using an electron cyclotron 10-20 MeV with a line quantity of 15-40 Gy (average 23.5 Gy). According to the treatment time, divided into 3 groups. There were 19 cases in the previous period (1976.4-1979.12), 19 cases in the middle period (1980.1-1983.3), and 32 cases in the later period (1983.4-1987.6). The average survival period during the treatment period was 4 months, 6 months in the middle period and 11.5 months in the latter period. There was a significant difference between the early and late periods (P<0.01).
