Sus antecedentes:
- La neoplasia intraepitelial prostática de alto grado (HGPIN) es un precursor común del cáncer de próstata.
- El manejo de HGPIN en la biopsia por aguja presenta un desafío clínico crucial.
- Comprender la base molecular del cáncer de próstata es vital para el diagnóstico y el tratamiento.
Objetivo del estudio:
- Para revisar los avances recientes en la patología del adenocarcinoma de próstata y la biología molecular.
- Para discutir las controversias de diagnóstico y gestión que rodean HGPIN.
- Explorar los fundamentos moleculares del cáncer de próstata, incluidas las alteraciones genéticas y los cambios en la expresión génica.
Principales métodos:
- Revisión de la literatura de nuevos hallazgos y temas controvertidos en el cáncer de próstata.
- Análisis de los criterios de diagnóstico y estrategias de gestión para HGPIN.
- Examen de las alteraciones moleculares y los patrones de expresión génica en el cáncer de próstata.
Principales resultados:
- El diagnóstico HGPIN en la biopsia con aguja conlleva un riesgo significativo de cáncer posterior.
- El sistema de calificación de Gleason influye críticamente en las decisiones de tratamiento para el cáncer de próstata.
- Numerosos cambios genéticos y perfiles de expresión génica alterados están implicados en el desarrollo y la progresión del cáncer de próstata.

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
