Delay in diagnosis and treatment initiation can be associated with adverse outcomes in children with cancer. Diagnostic interval (DI) is defined as the time between the date of first health care contact for symptoms related to cancer to the date of cancer diagnosis, and treatment interval (TI) is defined as interval between the definitive cancer diagnosis and cancer treatment initiation. We aimed to determine the predictors of DI and TI in children with rhabdomyosarcoma (RMS) and their association with event-free survival (EFS) and overall survival (OS).

诊断和治疗间隔与横纹肌肉瘤的生存无关：加拿大年轻人的癌症研究

诊断和治疗开始的延迟可能与癌症儿童的不良后果有关。诊断间隔 (DI) 定义为首次因癌症相关症状接触医疗保健人员的日期至癌症诊断日期之间的时间，治疗间隔 (TI) 定义为明确癌症诊断与癌症治疗开始之间的间隔。我们旨在确定横纹肌肉瘤 (RMS) 患儿 DI 和 TI 的预测因子及其与无事件生存期 (EFS) 和总生存期 (OS) 的关联。
