董新舒副教授直肠癌的病理类型属于腺癌,传统观点认为其对放疗不敏感,故很少采用放射治疗。随着放疗设备及方法的改进,我院自1978年起对直肠癌进行试验性放疗。通过10余年的临床及形态学研究结果表明,放射治疗并未能提高病人的生存率,但是可以明显降低复发率,提高手术切除率,此点与国外文献报告均相同。但是我认为对这一笼统的结果应加以区别分析。我们对放疗后的形态学研究结果表明,放疗主要适用于低分化腺癌及未分化癌,其与其它病理类型者放疗后癌细胞退变的对比表明,差异有显著性意义。所以我们主张术前放疗应针对低分化腺癌及未分化癌进行,而其它病理类型者不适合采用放疗。
Professor Dong Xinshu, the pathological type of rectal cancer, belongs to adenocarcinoma. The traditional view is that it is not sensitive to radiotherapy, so radiation therapy is rarely used. With the improvement of radiotherapy equipment and methods, our hospital has conducted experimental radiotherapy for rectal cancer since 1978. Through more than 10 years of clinical and morphological studies, radiation therapy has not been able to improve the survival rate of patients, but it can significantly reduce the recurrence rate and increase the surgical resection rate. This point is the same as the foreign literature reports. But I think that this general result should be analyzed differently. Our results of morphological studies after radiotherapy showed that radiotherapy is mainly applicable to poorly differentiated adenocarcinoma and undifferentiated carcinoma. The comparison of radiotherapy with other pathological types after radiotherapy showed that the difference was significant. Therefore, we advocate that preoperative radiotherapy should be performed for poorly differentiated adenocarcinoma and undifferentiated carcinoma, while other pathological types are not suitable for radiotherapy.
