概括
儿科狂肌肉瘤 (RMS) 的诊断时间缩短了,但这种改善并没有显著影响瘤特征或患者生存结果. 早期诊断提供了清晰度,但不会改变预后.
科学领域:
- 儿科瘤学 儿科瘤学
- 癌症研究 癌症研究
- 临床流行病学 临床流行病学
背景情况:
- 在儿科瘤学中,及时诊断对于优化治疗结果至关重要.
- 儿科拉布多米索尔科马 (RMS) 诊断的延迟可能会对瘤扩展和预后产生负面影响.
- 评估RMS诊断和治疗间隔的趋势对于改善患者护理至关重要.
研究的目的:
- 评估意大利儿科RMS患者的诊断和治疗开始的时间是否随着时间的推移而有所改善.
- 为了确定更长的诊断延迟是否与儿科RMS的瘤特征和预后有关.
- 分析诊断和治疗间隔对RMS儿童的生存结果的影响.
主要方法:
- 在1996年至2016年期间,对749名被诊断患有RMS的儿科患者进行了分析.
- 诊断间隔 (DI) 的定义是症状发作到诊断,治疗间隔 (TI) 是症状发作到治疗开始.
- DI与瘤特征的相关性以及使用卡普兰-梅尔分析对TI与存活率的分析.
主要成果:
- 中位数DI从39.5天 (1996-2000) 减少到30天 (2011-2016).中位数DI从39.5天 (1996-2000) 减少到30天 (2011-2016).中位数DI从39.5天 (1996-2000) 减少到30天 (2011-2016).中位数DI从39.5天 (1996-2000) 下降到30天 (2011-2016).中位数DI从39.5天 (1996-2000) 下降到30天 (2011-2016).中位数DI从39.5天 (1996-2000) 下降到30天 (2011-2016).
- 在单变体分析中,较长的DI与年龄,不利的组织学和转移性疾病有关,但在多变体分析中没有得到证实.
- 预后与年龄,不良部位,结节参与和转移性疾病有负相关性;TI没有影响生存率.
结论:
- 儿科RMS从症状发作到诊断的时间在近年来趋向于缩短.
- 虽然及时诊断提供了清晰度,并可能减少家长的焦虑,但它不会显著影响瘤特征或患者的结果.
- 诸如诊断时的年龄,瘤部位,结节参与和转移性疾病等因素是儿科RMS的关键预后指标.

Cancer Survival Analysis
624
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Introduction To Survival Analysis
701
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...
