What is Cancer?02:12

What is Cancer?

12.6K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Disorders of the Female Reproductive System

3.4K
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Cancer

51.6K
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 Progression02:07

Tumor Progression

6.8K
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...

Cancer Prevention

7.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Cancer Survival Analysis01:21

Cancer Survival Analysis

508
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Resumen
Este resumen es generado por máquina.

El tratamiento del cáncer de mama ha evolucionado con marcadores moleculares e inmunológicos, lo que permite terapias neoadyuvantes personalizadas y radioterapia desescalada. Los agentes dirigidos avanzados y las inmunoterapias ahora ofrecen opciones personalizadas para la enfermedad metastásica.

Área de la Ciencia:

  • En el campo de la oncología
  • Biología molecular
  • Inmunología

Sus antecedentes:

  • El cáncer de mama sigue siendo un cáncer líder a nivel mundial, con una comprensión que evoluciona a través de la caracterización molecular.
  • Los marcadores clave incluyen los inmunohistoquímicos (ER, PR, HER2, Ki-67), los genómicos (BRCA1/ 2, PIK3CA) y los inmunomarcadores (TIL, PD- L1).

Objetivo del estudio:

  • Para resaltar los avances en el diagnóstico y la terapia del cáncer de mama.
  • Para subrayar el cambio hacia la medicina personalizada basada en el perfil molecular.

Principales métodos:

  • Revisión de los algoritmos de diagnóstico actuales que incorporan múltiples combinaciones de biomarcadores.
  • Análisis de estrategias de tratamiento neoadyuvante y metastásico, incluidos los agentes dirigidos y la inmunoterapia.

Principales resultados:

  • Las terapias de combinación neoadyuvantes (HER2-positivo, triple negativo) son estándar, guiando las estrategias quirúrgicas de desescalada y post-tratamiento.
  • La terapia endocrina (5-10 años) y la quimioterapia se utilizan para los tumores ER positivos en función del riesgo.
  • El tratamiento metastásico incluye CDK4/ 6, PI3K, inhibidores de PARP y inmunoterapia anti-PD-L1, adaptada al perfil tumoral.

Conclusiones:

  • El tratamiento del cáncer de mama es cada vez más complejo, impulsado por los avances de los biomarcadores.
  • Las estrategias de tratamiento personalizado se están convirtiendo en estándar, desde la atención neoadyuvante hasta el manejo de la enfermedad metastásica.
