Summary
Prostate cancer (PCa) metastasis risk varies by anatomical location in African men. Lesions in the anterior fibromuscular stroma and central gland show higher metastatic potential, guiding targeted PCa management.
Area of Science:
- Oncology
- Urologic Oncology
- Cancer Metastasis Research
Background:
- Prostate cancer (PCa) exhibits diverse pathogenetic characteristics influenced by anatomical location.
- Understanding zonal variations in PCa is crucial for assessing metastatic risk, particularly in specific populations.
Purpose of the Study:
- To investigate the relationship between the anatomical origin of prostate cancer lesions and their metastatic potential in African men.
- To identify specific prostate zones associated with an increased risk of metastasis.
Main Methods:
- A retrospective observational study of 120 African men with biopsy-confirmed PCa between 2019-2023.
- Data collection included patient history, sociodemographics, and clinical characteristics from medical records.
- Logistic regression analysis was employed to determine predictors of metastasis.
Main Results:
- Prostate cancer lesions were most frequently detected in the peripheral and transitional zones.
- Lesions originating from the anterior fibromuscular stroma, central gland, and diffuse whole-gland infiltration were significantly associated with higher odds of metastasis.
- Anterior fibromuscular stroma lesions showed a marginally significant independent association with metastasis.
Conclusions:
- Prostate cancer metastatic risk is significantly influenced by the anatomical zone of origin in African men.
- Anterior fibromuscular stroma, central gland, and diffuse infiltration indicate elevated metastatic potential.
- Findings support the development of targeted diagnostic and therapeutic strategies based on lesion localization for improved PCa management in African populations.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
