概括
激进的乳腺切除术没有提供比简单的乳腺切除术或宽切除术等侵入性较小的乳腺癌治疗方法的生存益处,这两种治疗都需要放射治疗. 增加的发病率可能源于检测出不太具有侵略性的瘤.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 流行病学 流行病学
背景情况:
- 几十年来,乳腺癌发病率大幅上升.
- 尽管乳腺癌发病率增加,但乳腺癌死亡率仍保持稳定.
- 这表明诊断的乳腺癌类型的潜在转变.
研究的目的:
- 为了比较乳腺癌不同手术治疗的生存益处.
- 分析乳腺癌发病率和死亡率的趋势.
- 根据生存数据,研究乳腺癌患者群体的特征.
主要方法:
- 随机试验的综述,比较激进的乳房切除术,简单的乳房切除术与放射治疗,以及广泛的切除术与放射治疗.
- 对乳腺癌发病率和死亡率的历史数据的分析.
- 检查生存曲线以确定不同的患者群体.
主要成果:
- 激进的乳房切除术与简单的乳房切除术或广泛切除术相比没有生存优势,当与第一阶段乳腺癌的放射治疗相结合时.
- 生存分析表明有两个不同的患者群体:一个是治疗不影响的预后差,另一个是预后更好.
- 乳腺癌发病率的增加可能归因于检测出生物学上不那么具有攻击性,但在组织学上具有恶性瘤.
结论:
- 与放射治疗相结合的不那么激进的外科手术方法与激进的乳房切除术一样有效.
- 很大一部分乳腺癌患者可能患有目前治疗方法没有显著影响的疾病.
- 增加的发病率可能反映了惰性恶性瘤的更好检测,而不是侵略性疾病的真正增加.

02:56Treatment Resistant Cancers
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...
02:49Cancer 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...

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
01:21Cancer Survival Analysis
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...
