- 胃状细胞癌和腺状细胞癌 (G/GEJ-CSC) 是罕见的,异质的胃癌.
- 关于其临床病理特征和预后的有限的大规模数据存在.
- 传统观点认为G/GEJ-CSC更具侵略性,但证据很少.
研究的目的:
- 系统地调查G/GEJ-CSC.的临床病理特征和预后模式.
- 使用大规模队列,将G/GEJ-CSC与胃腺癌 (GAC) 进行比较.
- 提供支持G/GEJ-CSC.个性化治疗策略的证据.
主要方法:
- 来自江癌症医院和SEER数据库的G/GEJ-CSC和GAC患者的回顾性分析.
- 使用倾向得分匹配 (PSM) 来平衡患者队列.
- 采用卡普兰-梅尔和考克斯的比例危险模型来评估生存结果.
主要成果:

Cancer Survival Analysis
650
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...

Comparing the Survival Analysis of Two or More Groups
561
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Genome-wide Association Studies-GWAS
15.3K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Bias in Epidemiological Studies
1.3K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
