The ultrasonographic examination was applied for the purpose of volume estimation of rectal cancer. We have performed 15 cases of echographic volume estimation compared with that of resected specimen (control group) and mean volume estimation error rate was 14.6% between two methods. And we also performed 17 preoperative irradiation cases of rectal cancer. Each tumor volume of pre- and post-irradiation was estimated echogenically and was compared with that of resected specimen. In the case when irradiation effect was remarkable, estimated volume by ultrasonography was much smaller in post-irradiation compared with that of pre-irradiation. Same tendency was also recognized in the study of resected specimen. Histopathological irradiation effect was also highly recognized in the case when echographic diminished rate was prominent. This method will useful for the judgement of preoperative irradiation effect in rectal cancer.
应用超声检查来估计直肠癌的体积。我们对15例患者进行了超声体积估计，并与切除标本（对照组）进行比较，两种方法之间的平均体积估计误差率为14.6%。我们还对17例直肠癌术前放疗病例进行了研究。对放疗前后的每个肿瘤体积进行超声估计，并与切除标本进行比较。当放疗效果显著时，超声估计的放疗后体积比放疗前小得多。在对切除标本的研究中也发现了相同的趋势。当超声缩小率显著时，组织病理学上的放疗效果也得到高度认可。该方法将有助于判断直肠癌的术前放疗效果。
