概括
辅助放射疗法 (RT) 显著改善了二级常规软骨肉瘤 (cCS) 的无进展生存率,特别是在不完全切除后. 在完全切除后,仅仅进行手术可能就足够了,但需要进一步的证据来确定最佳的治疗策略.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 神经外科 神经外科
背景情况:
- 头骨底部软骨肉瘤需要量身定制的治疗策略.
- 2级常规软骨肉瘤 (cCS) 的最佳管理仍在调查中.
- 辅助放射治疗 (RT) 的作用及其最佳模式尚未明确定义.
研究的目的:
- 阐明2级常规软骨肉瘤 (cCS) 的最佳治疗策略.
- 评估辅助RT对2级cCS无进展生存 (PFS) 的影响.
- 为了比较不同治疗模式后的结果,对骨底部冠状腺瘤.
主要方法:
- 来自"头骨底部冠状癌联盟"的多机构数据的回顾性分析.
- 评估患者的人口统计,放射性特征和治疗结果.
- 使用临床和放射学随访数据评估疾病稳定性和进展.
- 统计分析包括相互作用模型和对对比,以确定RT对PFS的影响.
主要成果:
- 分析了79名患有2级cCS的患者队列 (平均随访时间为74.6个月).
- 辅助RT显著降低了疾病进展的可能性 (HR 0.26,p = 0.004).
- 辅助RT在不完全切除 (HR 3.73,p = 0.02) 后显示出显著的PFS益处,但在总切除 (GTR) 后的趋势不显著.
- 质子束RT (PBRT) 是主要的RT技术 (71%).
结论:
- 辅助RT适用于2级cCS的不完整切除,以优化长期瘤控制.
- 在完全切除后,经过密切跟踪的手术是一种可接受的策略,需要进一步调查.
- 质子束RT的剂量度能力可能对骨底部冠状腺瘤的局部控制至关重要.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Treatment Resistant Cancers
3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
