肠道寄生虫感染可导致癌症患者显着发病和死亡。尽管如此，它们在健康个体中通常是自我限制的。溶组织内阿米巴是一种厌氧寄生虫，可在感染者中引起阿米巴病。 卫生条件差和流行地区会增加感染阿米巴病的风险。此外，贾第鞭毛虫病是由十二指肠贾第鞭毛虫（一种有鞭毛的原生动物）引起的小肠寄生虫感染。在这两种情况下，免疫抑制患者的疾病负担更大，时间也更长。因此，我们的目的是通过介绍一例由溶组织内阿米巴引起的肠道阿米巴病和小肠结肠炎病例以及两例贾第鞭毛虫病病例，更全面地描述癌症患者中这些肠道寄生虫感染的疾病进展和治疗效果，同时还对文献。版权所有 © 2024，Kim 等人。

Intestinal parasitic infections can cause significant morbidity and mortality in individuals with cancer. Despite this, they are often self-limiting in healthy individuals. Entamoeba histolytica is an anaerobic parasite that causes amebiasis in infected individuals. Poor sanitary conditions and endemic areas increase the risk of contracting amebiasis. Furthermore, giardiasis is a parasitic infection of the small intestine that is caused by Giardia duodenalis, a flagellated protozoan. In both cases, the disease burden is greater and the timeline is longer among immunosuppressed patients. Due to this, we aimed to more thoroughly characterize disease progression and treatment efficacy of these intestinal parasitic infections in cancer patients by presenting a case of intestinal amebiasis and enterocolitis due to Entamoeba histolytica, as well as two giardiasis cases, while also providing a review of the literature.Copyright © 2024, Kim et al.
