概括
在乳腺癌患者接受新辅助疗法 (NAT) 后,单染色哨兵淋巴结活检 (SLNB) 是有效的,具有较低的假阴性率 (FNR). 识别更多的淋巴结可以提高准确性,特别是在某些患者群体.
科学领域:
- 在瘤学瘤学.
- 手术病理学手术病理学
- 乳腺癌研究研究 乳腺癌研究
背景情况:
- 国际指导方针建议在新辅助疗法 (NAT) 后降低乳腺癌患者的哨兵淋巴结活检 (SLNB) 中使用双重标记剂.
- 由于实际限制,大多数中国医院都使用单色SLNB,造成建议和实践之间的差距.
研究的目的:
- 为了评估单染色SLNB的错误阴性率 (FNR) 在NAT后乳腺癌患者.
- 为了确定影响单色SLNB的FNR的因素.
主要方法:
- 患有临床N1型乳腺癌的成年女性接受了NAT,随后使用单个染料和手臂淋巴结剖析进行了顺序SLNB.
- 主要终点是单色SLNB程序的FNR.
主要成果:
- 在201名患有结节转移的患者中,单色SLNB的整体FNR为8.96%.
- 在较年轻的患者 (<60岁),BMI <25 kg/m2,识别≥4个SLN和雌激素受体阴性瘤中观察到较低的FNR.
- 与更高的FNR独立相关的因素包括BMI≥25 kg/m2和雌激素受体阳性瘤. 识别更多的SLN与较低的FNR有关.
结论:
- 在cN1乳腺癌患者中,NAT后的单色SLNB获得了临床上可接受的FNR.
- 识别四个或更多的SLN为BMI<25 kg/m2和负雌激素受体状态的患者提供了额外的好处.

Cancer Therapies
10.2K
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...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Clinical Trials
10.9K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical Trials: Overview
5.1K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Detailed Structure and Function of Lymph Nodes
5.2K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
