Prostate cancer is one of the most common diseases among men, and understanding the risk factors and the importance of early detection is crucial for improving health outcomes. With the right knowledge about the symptoms and diagnostic options, proactive steps can be taken to address this challenge. We will explore in depth how early detection and risk assessment can make a significant difference in the fight against prostate cancer, giving patients better opportunities for effective treatment and a successful recovery.
Prostate cancer is one of the most common types of cancer affecting men worldwide.
Each year, Prostate Cancer Day gives us the opportunity to reflect on the importance of early detection and the innovations available that allow for a more effective diagnosis of this disease.
What is Prostate Cancer?
The prostate is a gland found only in men, located below the bladder and in front of the rectum. Its main function is to produce seminal fluid, which nourishes and transports sperm. Prostate cancer occurs when cells in the prostate begin to grow uncontrollably. Although it may not cause symptoms in its early stages, as it progresses, it can cause urinary problems, pelvic pain, and in more advanced stages, bone pain and other serious symptoms.
Population Incidence and Risk
Prostate cancer is the second most common type of cancer among men, After lung cancer, breast cancer is the second most common cancer in the world. According to the WHO, more than 1.3 million new cases are diagnosed each year globally. The incidence varies significantly by region, being highest in North America, Western Europe, and Australia. However, in Spain alone, the projected incidence for 2024 has increased to 30,316 new cases.
This type of cancer is one of the tumors that usually appear at older ages, being diagnosed generally from age 65 onwards, with a higher incidence between 70 and 75 years of age, while for those under 50 years old it is usually around 1%.
The origin or causes of prostate cancer remain largely unknown and are the subject of study.
However, some factors are known to increase the likelihood of developing it. Some risk factors include:
- Age: The risk usually increases significantly from age 50 onwards.
- Ethnicity: This type of cancer is more common in African American men, and they are also more likely to develop it at a younger age.
- Diet and lifestyle: Several studies have linked certain eating habits as a risk factor, for example, the intake of saturated animal fats, red meat, dairy products with high calcium content, etc.
- Family history and genetic factors: At least 20% patients with this cancer have a family history. Inherited genetic factors increase the risk when high-penetrance alleles are inherited.
Screening Methods
Early detection is fundamental in any type of cancer for the selection of an effective treatment and thus prolong the patient's life. For a long time, the digital rectal exam was the primary screening test for prostate cancer. In the late 1980s, the prostate-specific antigen (PSA) test was developed for prostate cancer surveillance. This test allows for the simple detection of elevated levels of this antigen in the early stages, which can indicate the presence of prostate cancer.
Although these methods have been useful, they also have limitations, such as false positives and false negatives, which can lead to overdiagnosis and unnecessary treatments.
Genetics is opening new avenues in the diagnosis and management of prostate cancer. One of the most promising approaches is the polygenic risk score (PRS).
Using a blood or saliva sample, the patient's DNA is analyzed to identify genetic variants associated with prostate cancer. These variants are combined to generate a total score that indicates the relative risk of developing the disease.
Several studies have linked hundreds of common genetic polymorphisms associated with risk of developing prostate cancer and currently, It is estimated that these variants explain between 28-33% of the familial risk of prostate cancer.
Some of the advantages of using PRS as a prevention tool include:
- Screening customization: PRSs could help explain genetic risk in patients who do not have mutations in panels of genes related to prostate cancer.
- Reduction of overdiagnoses: When assessing genetic risk, the predictive value of the prostate-specific antigen test is improved, which can be elevated by other causes such as benign prostatic hyperplasia.
- Prevention and management: Knowing the genetic risk provides the specialist with additional information for a more accurate assessment of the patient's risk, with which to design a more appropriate medical management.
Prostate risk assessments (PRS) are an innovative and promising tool for estimating the risk of common diseases, offering an advantage in risk factor assessment in clinical practice. The clinical implementation of PRS for prostate cancer requires integrating genetic testing with current screening methods to provide a comprehensive risk assessment.
