A 52-year-old man presented with palatine tonsillar swelling caused by follicular lymphoma. His tumor burden was low, but exacerbation of snoring and dysphagia was observed. Considering the first wave of coronavirus disease 2019 (COVID-19) pandemic, he received palliative 4-Gy irradiation to the tonsils in 2 fractions, which induced partial regression of tonsillar swellings and eradication of the circulating lymphoma cells. We suggest that low-dose radiotherapy triggered an abscopal effect of lymphoma, which allowed the patient time to receive COVID-19 vaccination before starting immunosuppressive chemo-immunotherapy.
一位 52 岁男性因滤泡性淋巴瘤而出现腭扁桃体肿胀。他的肿瘤负担较低，但观察到打鼾和吞咽困难加重。考虑到第一波 2019 年冠状病毒病（COVID-19）大流行，他接受了 4Gy 的姑息性双剂量扁桃体照射，这导致扁桃体肿胀部分消退和循环淋巴瘤细胞消除。我们建议低剂量放疗引发了淋巴瘤的远隔效应，使患者有时间在开始免疫抑制化疗免疫治疗之前接种 COVID-19 疫苗。
