鼻腔浆细胞瘤甚为罕见。本文报告经放射治疗的鼻腔浆细胞瘤4例,包括单纯体外放射2例,术后放射2例。肿瘤剂量按肿瘤大小或术后残留情况而不同。未经手术或术后有肉眼残留瘤组织者,最少照射TDF87,肿瘤巨大者局部照射达TDF105。术后无肉眼残留瘤组织者,照射TDF62。4例中,除1例因其他疾病于治疗后第2年突然死亡外,其余3例治疗后均生存10年以上。 Nasal plasmacytoma is very rare. In this paper, we report 4 cases of nasal plasmacytoma by radiotherapy, including 2 cases of simple external radiation and 2 cases of postoperative radiation. The tumor dose varies according to the size of the tumor or the postoperative residual conditions. Without surgery or postoperative macrosurgery, TDF87 was minimally irradiated and TDF105 was locally irradiated in giant tumors. TDF62 was irradiated in patients with no gross residual tumor tissue after surgery. In addition to 1 case of sudden death due to other diseases in the second year after treatment, the remaining 3 cases survived for more than 10 years after treatment.
