[Correlations between PRL and 17-beta-E in human breast cancer]
Summary
Prolactin serves as a valuable marker for breast cancer progression, especially in metastatic cases. Estradiol (E-17-beta) levels fluctuate with tumor growth and treatment, but show no direct correlation with prolactin.
Area of Science:
- Endocrinology
- Oncology
- Biochemistry
Context:
- Investigating hormonal biomarkers in breast cancer.
- Understanding the roles of prolactin and estradiol (E-17-beta) in disease progression.
- Analyzing hormonal changes in premenopausal and post-menopausal patients.
Purpose:
- To determine the correlation between prolactin and E-17-beta in breast cancer.
- To evaluate prolactin as an evolutive marker for breast cancer.
- To assess the behavior of E-17-beta in relation to tumor status and treatment.
Summary:
- Prolactin increases with metastatic breast cancer growth and may serve as an evolutive marker.
- Estradiol (E-17-beta) levels decrease post-tumor removal and chemotherapy, but increase with metastasis.
- No direct correlation was found between prolactin and E-17-beta; prolactin's increase is linked to the hypothalamic-hypophyseal system, while E-17-beta may have ectopic production.
Impact:
- Provides insights into the distinct roles of prolactin and estradiol in breast cancer.
- Suggests prolactin's utility in monitoring disease progression.
- Highlights potential ectopic E-17-beta production, possibly modulated by prolactin.

Correlations
36.2K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation
42.8K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.

Correlation
15.2K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Correlation and Regression
3.5K
In statistics, correlation describes the degree of association between two variables. In the subfield of linear regression, correlation is mathematically expressed by the correlation coefficient, which describes the strength and direction of the relationship between two variables. The coefficient is symbolically represented by 'r' and ranges from -1 to +1. A positive value indicates a positive correlation where the two variables move in the same direction. A negative value suggests a...

Coefficient of Correlation
8.7K
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...

Spearman's Rank Correlation Test
1.5K
Spearman's rank correlation test, also known as Spearman's rho, is a nonparametric method for assessing the strength and direction of association between two variables. This test is particularly valuable when the data distribution is unknown or when the assumption of normality does not hold. Named after the English psychologist and statistician Dr. Charles Edward Spearman, it serves as the nonparametric counterpart to Pearson's correlation coefficient.
