This erratum corrects the following:

Elad S, Cheng KKF, Lalla RV, et al. Mucositis Guidelines Leadership Group of the Multinational Association of Supportive Care in Cancer and International Society of Oral Oncology (MASCC/ISOO). MASCC/ISOO clinical practice guidelines for the management of mucositis secondary to cancer therapy. Cancer. 2020;126:4423-4431. doi: 10.1002/cncr.33100

In the aforementioned article, in the section Natural and Miscellaneous Agents, the sentence should read as follows (correction bolded):

“This guideline is based on 2 RCTs showing that a glutamine dose from 10 to 30 g daily during RT-CT may prevent OM.”

There was a typographical error: the unit should be grams, not milligrams.

The authors regret this error.

此勘误更正了以下内容：

Elad S、Cheng KKF、Lalla RV 等。多国癌症支持治疗协会和国际口腔肿瘤学会 (MASCC/ISOO) 的粘膜炎指南领导小组。MASCC/ISOO 治疗继发于癌症治疗的粘膜炎的临床实践指南。癌症。2020;126:4423-4431。doi：10.1002/cncr.33100

在上述文章中，在自然和杂项代理部分，句子应如下（更正粗体）：

“该指南基于 2 项 RCT，表明RT-CT 期间每天10 至 30克的谷氨酰胺剂量可以预防 OM。”

有一个印刷错误：单位应该是克，而不是毫克。

作者对这个错误感到遗憾。
