Li-Fraumeni syndrome (LFS) is a rare inherited disease characterized by a high and early-onset cancer risk. A cancer surveillance program is important to reduce cancer-related morbidity and mortality in individuals with LFS. We report 2 pediatric cases with LFS-related malignancy in a family. Eight-year-old elder brother was diagnosed with adrenocortical carcinoma and was found to have a heterozygous missense germline mutation c.736A>G: p.Met246Val in the TP53 gene. Cancer screening led to the diagnosis of rhabdomyosarcoma at a curable stage in his 2-year-old younger brother. Comprehensive surveillance resulted in early tumor detection and improved survival.
李-佛美尼综合征（LFS）是一种罕见的遗传性疾病，其特征是癌症风险高且发病早。癌症监测计划对于降低LFS患者的癌症相关发病率和死亡率很重要。我们报告了一个家族中2例与LFS相关的儿童恶性肿瘤病例。8岁的哥哥被诊断为肾上腺皮质癌，发现其TP53基因存在杂合错义种系突变c.736A>G：p.Met246Val。癌症筛查使得他2岁的弟弟在可治愈阶段被诊断出横纹肌肉瘤。全面监测导致早期肿瘤检测并提高了生存率。
