Base Excision Repair01:54

Base Excision Repair

21.8K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Skin Cancer

3.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

概括

软组织肉瘤 (STS) 的意外切除可以通过更好的外科医生教育来避免. 在非计划性切除后重新切除不会增加复发率,但对患者来说不如计划性切除对患者来说更不理想.

科学领域:

  • 在瘤学瘤学.
  • 手术病理学手术病理学
  • 放射学 放射学是一门学科.

背景情况:

  • 软组织肉瘤 (STS) 是罕见且异质的,在块的差异诊断中经常错过.
  • 无计划切除 (UE) 经常发生在非专业的中心.
  • 手术后的MRI可能难以解释,因为,血瘤和血清瘤,复杂的残留瘤和手术变化之间的区分.

研究的目的:

  • 评估软组织肉瘤的意外切除 (UE) 后的再切除 (RE) 的结果.
  • 为了比较重新切除结果与计划切除 (PE).
  • 要突出UE的患者和临床影响,其次是RE与PE.

主要方法:

  • 倾向性得分匹配分析被用来比较患者的结果.
  • 分析的结果包括死亡率和局部复发率.
  • 手术方法 (PE与UE,其次是RE) 是主要的比较因素.

主要成果:

  • 与PE患者相比,在UE后接受RE的患者的死亡率或局部复发率并不高.
  • 再切割程序往往需要复杂的重建.
  • 对患者来说,计划切除是最好的,尽量减少住院时间和工作时间.

结论:

  • 软组织肉瘤意外切除后的重新切除在瘤学上与计划切除在复发和死亡率方面相似.
  • 通过持续的外科医生教育,最大限度地减少无计划切除至关重要.
  • 优化软组织肉瘤的手术规划和执行对于改善患者的结果和资源利用至关重要.
