Resumen
Los nuevos modelos predicen el riesgo de carcinoma basocelular (BCC) en los sobrevivientes de cáncer infantil, superando las pautas actuales. Una calculadora en línea ahora puede guiar el cribado personalizado basado en el riesgo para la salud a largo plazo.
Área de la Ciencia:
- En el campo de la oncología
- Epidemiología
- Estadísticas biológicas
Sus antecedentes:
- Los sobrevivientes de cáncer infantil tienen un mayor riesgo de carcinoma basocelular (BCC).
- Las directrices actuales de detección pueden no estratificar con precisión el riesgo de BCC en esta población.
- Es necesario desarrollar modelos precisos de predicción de riesgos específicos de la edad para el cribado específico.
Objetivo del estudio:
- Desarrollar y validar modelos específicos de edad para predecir el riesgo de CBC en sobrevivientes de cáncer infantil.
- Comparar el rendimiento de nuevos modelos de predicción con las directrices de cribado existentes.
- Proporcionar una herramienta para informar las recomendaciones de cribado personalizadas.
Principales métodos:
- Utilizó datos de 23,166 sobrevivientes de cinco años en el Estudio de Sobrevivientes de Cáncer Infantil (CCSS).
- Desarrollo de modelos estadísticos y de aprendizaje automático, incluido XGBoost, que incorporan predictores detallados del tratamiento del cáncer.
- Modelos validados externamente en 5,314 sobrevivientes de la cohorte de St Jude Lifetime (SJLIFE) y desempeño evaluado utilizando AUROC y AUPRC.
Principales resultados:
- La incidencia acumulada de BCC a los 50 años fue del 15% en CCSS y del 21% en SJLIFE.
- Los modelos XGBoost demostraron una fuerte discriminación (AUROC40y = 0,75, AUROC50y = 0,76) y precisión (AUPRC40y = 0,20, AUPRC50y = 0,52).
- Los nuevos modelos superaron las directrices actuales del Grupo de Oncología Infantil (COG), reclasificando proporciones significativas de sobrevivientes para el cribado estratificado por riesgo.
Conclusiones:
- Los modelos validados de predicción de riesgo de BCC para los sobrevivientes de cáncer infantil superan significativamente las pautas de práctica actuales.
- Los modelos desarrollados y la calculadora de riesgos en línea asociada pueden respaldar recomendaciones de detección personalizadas basadas en la evidencia.
- Estas herramientas pueden ayudar a optimizar la atención de seguimiento a largo plazo para los sobrevivientes de cáncer infantil, mejorando los resultados de salud.

Skin Cancer
4.5K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Cancer Survival Analysis
453
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...

The Retinoblastoma Gene
4.2K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancer Stem Cells and Tumor Maintenance
5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Cancer Prevention
6.3K
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.

Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...
