概括
患有扩散性大B细胞淋巴瘤 (DLBCL) 患有二次癌症的患者表现出不同的生存结果. 肺癌患者的生存率更高,而其他患者的预后更差,这凸显了长期随访的必要性.
科学领域:
- 在瘤学瘤学.
- 流行病学 流行病学
- 癌症的生存率 癌症的生存率
背景情况:
- 扩散性大B细胞淋巴瘤 (DLBCL) 幸存者患二次原发性恶性瘤 (SPMs) 的风险增加.
- 关于DLBCL患者中SPM的结果的数据有限.
研究的目的:
- 检查DLBCL患者中SPM的特征,总生存率 (OS) 和治疗方法.
- 为了将DLBCL患者的SPM结果与一般人口队列进行比较.
主要方法:
- 使用了监测,流行病学和最终结果 (SEER) 注册表.
- 检查了DLBCL患者,这些患者患有乳腺,前列腺,肺部,结肠/直肠,膀癌,黑色素瘤,髓瘤和急性白血病.
- 根据年龄,性别,种族,诊断年份和阶段,将DLBCL患者与50名普通人群对照匹配.
主要成果:
- 患有肺癌或结肠/直肠癌的DLBCL患者更经常在早期阶段被诊断出来.
- 包括前列腺癌,黑色素瘤,骨髓瘤和急性白血病在内的SPM与DLBCL患者的显著更糟糕的OS有关.
- 在DLBCL之后的肺癌显示出明显改善的生存率. 在老年DLBCL患者中,强化治疗改善了SPM的生存状况,除了髓瘤和急性白血病.
结论:
- 这些发现有助于临床医生了解DLBCL患者的SPM存活率.
- 建议对DLBCL幸存者进行长期随访,以检测SPM.

01:15Secondary Lymphoid Organs
1.3K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

6.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:23Cells of the Adaptive Immune Response
970
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
