Familial prostate cancer is a malignant neoplasm that develops in the tissues of the prostate gland. This pathology is most common among men, and its characteristic feature is slow progression, which in some cases makes early diagnosis difficult. Prostate cancer can manifest itself in various forms, among which adenocarcinoma is the most common. Research shows that the disease often has a familial nature, which implies the presence of a genetic predisposition that increases the risk of its development among close relatives.
History of the disease and interesting historical facts
Prostate cancer has been known since ancient times. The first mention of prostate diseases can be found in the works of Hippocrates, who described symptoms reminiscent of modern manifestations of prostate cancer. The first scientific studies concerning this pathology began to appear at the end of the 19th century, when scientists began to systematically study morphological changes in prostate tissue. Interesting fact: in 1941, hormonal treatment methods were proposed, which became a turning point in oncology. Leading medical institutions in the world continue to study the genetics and molecular biology of prostate cancer, opening new horizons for diagnosis and treatment.
Epidemiology
Prostate cancer is the second most common malignant tumor in men worldwide. According to the World Health Organization, about 1.4 million new cases of the disease were registered in 2020. In Russia, according to the N. N. Blokhin Russian Cancer Research Center, the incidence of prostate cancer is approximately 15 cases per 100,000 men. The peak incidence is observed at the age of 65-74 years. It is worth noting that regions with a high level of diagnosis, such as North America and Western Europe, demonstrate high incidence statistics, which may be due to active screening.
Genetic predisposition to this disease
Genetic predisposition to prostate cancer has been studied for decades. Modern research has shown that mutations in the BRCA1 and BRCA2 genes, as well as in the HOXB13 and ATM genes, significantly increase the risk of developing the disease. According to research, men with close relatives suffering from prostate cancer have a 2-3 times increased risk of developing the disease themselves. However, not all cases of prostate cancer are related to heredity; many factors, such as epigenetic mechanisms, may also play an important role.
Risk factors for the development of this disease
Risk factors for prostate cancer are varied and can be both endogenous and exogenous. The main risk factors include:
- Age – the risk increases after 50 years.
- Family history – presence of cases of prostate cancer in close relatives.
- Ethnicity – African Americans have the highest risk.
- Testosterone levels – high levels may contribute to tumor development.
- Obesity - metabolic disorders can also increase the risk.
- Diet – High consumption of red meat and dairy products is associated with risk.
Diagnosis of this disease
Prostate cancer diagnostics involves several stages, each of which uses a specific technique to determine the presence of the disease. The main symptoms may be subtle, so it is important to pay attention to the following symptoms:
- Difficulty urinating.
- Frequent urge to urinate, especially at night.
- Pain in the pelvic or back area.
For laboratory research the following are used:
- Prostate specific antigen (PSA) test.
- Prostate biopsy is the gold standard for confirming the diagnosis.
Radiological examinations include:
- Ultrasound examination (US) of the pelvic organs.
- Magnetic resonance imaging (MRI) to assess tumor spread.
Differential diagnosis is carried out with other diseases of the prostate gland, such as benign hyperplasia and inflammatory processes.
Treatment
Treatment for prostate cancer can vary widely and depends on the stage of the disease, the patient's age, and overall health. The main approaches to treatment include:
- Surgical intervention – radical prostatectomy, aimed at complete removal of the organ.
- Radiotherapy is both an external and an intra-organ form of treatment.
- Hormone therapy – used to reduce testosterone levels, which slows the growth of tumors.
- Chemotherapy – used in the later stages of the disease.
List of medications used to treat this disease
The main drugs used in the treatment of prostate cancer include:
- Abirataka (Abiraterone)
- Pisotor (Enzalutamide)
- Doxorubicin
- Sulamid (Sutent)
Disease monitoring
Prostate cancer monitoring involves regular examinations and laboratory tests to track the dynamics of the disease. Key control stages include:
- Regular PSA tests.
- Routine examinations with a urologist.
The prognosis of the disease depends on the stage at which the diagnosis was made. With early diagnosis and timely treatment, 5-year survival can exceed 95%. However, complications such as metastases and the development of other tumors are possible.
Age-related features of the disease
Different age groups of patients exhibit different clinical manifestations and progression of prostate cancer. Men under 60 years of age often present with aggressive forms of prostate cancer, while older men often have less aggressive tumors that require observation rather than active therapy.
Questions and Answers
- What are the main symptoms of prostate cancer? The main symptoms are difficulty urinating, frequent urge to urinate, pain in the pelvic or back area.
- How to check PSA level in blood? The PSA test is performed in a lab after blood is drawn, usually through a vein in the arm.
- Can prostate cancer be prevented? There is no complete prevention, but maintaining a healthy lifestyle and regular medical examinations can reduce the risk.
- What is the outlook for prostate cancer treatment? Modern treatment methods can significantly improve the prognosis and quality of life of patients, especially if detected early.
- What are the most common types of treatment? The most common treatments include surgery, radiation therapy, and hormonal therapy.
Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov recommends paying attention to early symptoms of the disease and not ignoring annual medical examinations, especially for men over 50. It is also worth monitoring your lifestyle: a balanced diet, physical activity, and maintaining a normal weight can reduce the likelihood of developing the disease. Awareness of your family history of diseases is important for choosing a monitoring and prevention strategy. Discuss all your concerns with your doctor and monitor your test results to identify possible problems in time.
