Description

The incidence of prostate cancer varies greatly by region, age, and ethnicity. Higher rates are observed in North America and Europe compared with Asia and Africa. According to recent studies, men aged 65 years and older account for the majority of diagnoses, with significantly higher incidence rates among African-American men compared with their Caucasian counterparts. The development of prostate cancer is a multifactorial process involving genetic mutations, epigenetic changes, and alterations in cell signaling pathways. Androgens, primarily testosterone, are important for normal prostate function and development. Prostate cancer often involves dysregulation of Androgen Receptor (AR) signaling, leading to increased cell proliferation and survival. Androgen Deprivation Therapy (ADT) is a main treatment for advanced disease, but resistance often develops, requiring new therapeutic strategies. Prostate cancer is characterized by a variety of genetic mutations and chromosomal abnormalities. In particular, alterations in the tumor suppressor gene PTEN (Phosphatase and TENsin homolog) and the TMPRSS2-ERG (Trans-Membrane PRotease, Serine 2: Ets Related Gene) gene fusion are common in prostate tumors. These genetic alterations contribute to tumor progression and treatment resistance, highlighting the need for targeted therapies.

The tumor microenvironment plays a critical role in prostate cancer progression. Chronic inflammation, mediated by immune cells and cytokines, is increasingly recognized as a contributing factor to tumorigenesis. Targeting inflammatory pathways may provide new avenues for treatment. Early detection is essential to improve outcomes in the management of prostate cancer. The most common diagnostic approaches include Prostate-Specific Antigen (PSA) testing, Digital Rectal Examination (DRE), and biopsy. Although elevated PSA levels can indicate prostate cancer, they are not conclusive, leading to debate about the pros and cons of routine screening. Confirmation of cancer is usually obtained by trans-rectal or trans-perineal biopsy, often guided by imaging techniques such as MRI. Management of prostate cancer is modified to the stage of the disease, the patient's overall health, and personal preferences. Treatment modalities include active surveillance, surgery, radiotherapy, hormonal therapy, chemotherapy, and immunotherapy.

Radical prostatectomy is a standard treatment for localized prostate cancer, and external beam radiation therapy and brachytherapy are effective for localized disease. Immunotherapies, such as Sipuleucel-T, harness the body's immune system to target cancer cells, and ADT remains a mainstay treatment for advanced prostate cancer. Newer hormonal agents such as abiraterone and enzalutamide offer additional options for the management of castration-resistant disease, thereby improving overall survival rates. Chemotherapy is usually reserved for metastatic or castration-resistant prostate cancer. Docetaxel and Cabazitaxel have shown their effectiveness in prolonging survival in these conditions. Understanding the genetic and molecular profiles of tumors can lead to personalized treatment strategies that optimize outcomes. New biomarkers are being used for early detection and monitoring response to treatment remains an important aspect. Exploring the role of lifestyle modifications, including diet and exercise, in conjunction with traditional treatments can improve patient outcomes.

Prostate cancer represents a major challenge to men's health, requiring ongoing research and innovative management strategies. Advances in our understanding of epidemiology, pathophysiology, and treatment options offer hope for improved patient outcomes. A focus on personalized medicine, early detection, and addressing health disparities will be critical in the ongoing fight against this widespread disease. Prostate cancer, a major health problem affecting men worldwide, represents a complex interaction of genetic, environmental, and lifestyle factors. This article reviews recent advances in our understanding of the pathophysiology, risk factors, diagnostic methods, and treatment options of prostate cancer. By synthesizing current knowledge, we aim to highlight critical areas for future research and clinical practice, emphasizing the importance of personalized medicine to improve patient outcomes.
