The primary tumor regression pattern of 50 patients with nasopharyngeal carcinoma was reported. The tumor regression was monitored either by indirect nasopharyngeal mirror examination and biopsy or fiberoptic endoscope and biopsy. Fiberoptic endoscope and biopsy was found to be more accurate in noting residual tumor. It is recommended that booster radiation dose to the residual primary tumors be withheld unless positive biopsy samples persist at 10 or more weeks after radiotherapy.
报告了50例鼻咽癌患者的原发肿瘤消退模式。通过间接鼻咽镜检查及活检或纤维内镜及活检来监测肿瘤消退情况。发现纤维内镜及活检在发现残留肿瘤方面更为准确。建议除非放疗后10周或更长时间仍有阳性活检样本，否则不应给予残留原发肿瘤追加放疗剂量。
