概括
慢性髓性白血病 (CML) 患者的治疗决策是复杂的,这些患者未能达到反应里程碑. 持续的氨酸激酶抑制剂 (TKI) 治疗可能仍然有利于失败的CML患者,为风险治疗提供了替代方案.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 慢性髓性白血病 (CML) 患者未能达到应答里程碑的治疗调整是有争议的,因为伴随性疾病,药物毒性和移植的风险.
- 对于那些没有达到治疗响应里程碑的CML患者的长期生存结果,数据有限.
研究的目的:
- 系统地分析CML患者的长期存活率,以实现或未能达到预定义的分子响应里程碑为基础.
- 为修订当前应答里程碑提供证据,并为CML患者的个性化治疗决策提供信息.
主要方法:
- 从CML研究IV中分析了1342名慢性阶段的CML患者,并定期进行分子监测.
- 基准生存分析基于BCR-ABL1IS水平 (<0.1%,0.1-1%,>1-10%,>10%) 在3,6,12和24个月进行,随访时间长达14年.
- 评估年龄和转换为替代疗法对生存结果的影响.
主要成果:
- 失败里程碑的患者 (>10%的BCR-ABL1IS在6个月,>1%的BCR-ABL1IS在12个月) 的10年至12年的存活率约为80%,比响应的患者低约10%.
- 在26.9%的患者中,切换到替代疗法并没有改变主要的生存结果.
- 年龄影响危险比率和CML特异性存活率,但不是整体存活率差异.

Cancer Stem Cells and Tumor Maintenance
5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Treatment Resistant Cancers
3.3K
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...

Tumor Progression
6.4K
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...

Stem Cell Therapy for Tissue Regeneration
4.1K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Bone Marrow Sampling and Transplants
356
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Kaplan-Meier Approach
178
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
