- 现代治疗方案旨在优化存活率并最大限度地减少复发.
- 乳腺切除术后放射治疗 (PMRT) 在这个特定的患者群体中的作用需要详细研究.
研究的目的:
- 评估PMRT在pT3N0-1M0乳腺癌患者的治疗疗效.
- 评估PMRT对无病生存期 (DFS),总生存期 (OS) 和局部区域复发 (LRR) 的影响.
- 确定PMRT在当代治疗框架中的独立预后意义.
主要方法:
- 对222名经过乳腺切除术的pT3N0-1M0乳腺癌患者的临床数据的回顾性分析.

Cancer Survival Analysis
353
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
93
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
