评定肿瘤治疗效果的国际标准:①所有肿瘤消失期限不少于4周定为完全有效。②肿瘤缩小50%以上期限不少于4周为部分有效。③肿瘤缩小不到50%或增大不超过25%,未出现新肿瘤为无效。④肿瘤增大25%以上,出现新肿瘤为恶化。作者根据上述标准评定543例喉癌的放射治疗效果,都经组织学检查证实诊断。施行手术前放疗或姑息性放疗。远距γ线治疗482例,深部X线治疗58例,γ线加深部X线治疗3例。总局灶剂量22.3～77.4Gy。手术前放疗总局灶剂量40～46Gy。有些病例剂量较小是由于放疗过程中出现软骨膜炎或喉癌恶化。治愈的病例观察1年以上无复发。都进行远期随诊,
International criteria for assessing the efficacy of cancer treatment: 1 All tumors disappeared for a period of no less than 4 weeks were considered to be completely effective. 2 The reduction of tumors by 50% over a period of not less than 4 weeks is partially effective. 3 The tumor shrinks less than 50% or increases no more than 25%, and no new tumor appears to be ineffective. 4 Tumors increased by more than 25% and new tumors deteriorated. The authors assessed 543 cases of laryngeal carcinoma radiotherapy according to the above criteria and were confirmed by histological examination. Preoperative radiation or palliative radiotherapy is performed. Long-distance γ-ray treatment of 482 cases, deep X-ray treatment of 58 cases, γ-ray deepening X-ray treatment in 3 cases. The total focal dose was 22.3-77.4Gy. The preoperative total radiotherapy dose is 40-46 Gy. In some cases, the smaller dose is due to perichonditis or worsening of laryngeal cancer during radiotherapy. The cured cases were observed without recurrence for more than one year. All follow up in the future,
