What is bilateral retinoblastoma?
The retinoblastoma tumor(s) originate in the retina, the light sensitive layer of the eye that enables the eye to see. When the tumors are present in one eye, it is referred to as unilateral retinoblastoma, and when it occurs in both eyes it is referred to as bilateral retinoblastoma.
Is retinoblastoma usually bilateral?
Children born with a mutation in the RB1 gene usually develop retinoblastoma in both eyes (known as bilateral retinoblastoma), and there are often several tumors within the eye (known as multifocal retinoblastoma).
What causes bilateral retinoblastoma?
Heritable or bilateral retinoblastoma About 9 of 10 children who are born with this RB1 germline mutation develop retinoblastoma. This happens when the second RB1 gene is lost or mutated. Most often the retinoblastoma is bilateral (in both eyes), but sometimes it is found early enough that it is still only in one eye.
Is bilateral retinoblastoma rare?
Retinoblastoma may affect one or both eyes. In about two-thirds of all cases only one eye is affected. Retinoblastoma is rare, with about 250–300 children diagnosed in the U.S. each year.
Is retinoblastoma life threatening?
Retinoblastoma is often curable when it is diagnosed early. However, if it is not treated promptly, this cancer can spread beyond the eye to other parts of the body. This advanced form of retinoblastoma can be life-threatening.
What happens if retinoblastoma goes untreated?
Untreated, retinoblastoma can spread widely: Throughout the retina. Throughout the fluid inside the eye (also called the vitreous). Large tumors may detach from the retina and break into smaller tumors, called vitreous seeds.
Is retinoblastoma benign or malignant?
A retinoblastoma is a malignant tumor of the retina, occurring most often in young children below 5 years. In one of three cases it is bilateral i.e., affecting both eyes.
What is the life expectancy of someone with retinoblastoma?
The 5-year survival rate tells you what percent of children live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for children with retinoblastoma is 96%.
What is the lifespan of someone with retinoblastoma?
Doctors often use the observed survival rate when they talk about a prognosis. The 5-year observed survival for retinoblastoma in children 0 to 14 years of age is 96%. This means that, on average, 96% of children diagnosed with retinoblastoma are expected to live at least 5 years after their diagnosis.
What are the warning signs of retinoblastoma?
Symptoms
- A white color in the center circle of the eye (pupil) when light is shone in the eye, such as when someone takes a flash photograph of the child.
- Eyes that appear to be looking in different directions.
- Poor vision.
- Eye redness.
- Eye swelling.
Can retinoblastoma come back after surgery?
While it is unlikely, retinoblastoma can come back after treatment. Children are at highest risk for recurrence until age 6, but retinoblastoma can even return later in life.
Can chemotherapy cure retinoblastoma?
Systemic chemo is given in cycles, with each treatment followed by a rest period to give the body time to recover. Each chemo cycle typically lasts for a few weeks, and the total length of treatment is often several months. Some of the chemo drugs used to treat retinoblastoma include: Carboplatin.
¿Qué es el retinoblastoma?
El retinoblastoma es causado por una mutación en un gen que controla la forma como las células se dividen. En consecuencia, las células se multiplican fuera de control y se vuelven cancerosas. En aproximadamente la mitad de los casos, esta mutación se desarrolla en un niño cuya familia nunca ha tenido cáncer en el ojo.
¿Qué es la radioterapia local para retinoblastoma?
Radioterapia local: para casos de retinoblastoma con tamaño superior a 16 mm se desaconseja la crioterapia y la fotocoagulación. Termoterapia transpupilar: con energía láser y luz infrarroja aplica calor sobre las células afectadas y los vasos sanguíneos cercanos destruyendo el tejido.
¿Cómo se puede propagar el retinoblastoma?
El tumor se puede diseminar a la órbita a través del nervio óptico e igualmente se puede propagar al cerebro, los pulmones y los huesos. Llame a su proveedor si se presentan signos o síntomas de retinoblastoma, en especial si los ojos de su hijo se ven o parecen anormales en las fotografías.
¿Qué es un seguimiento activo de pacientes con retinoblastoma?
Un seguimiento activo de estas personas puede lograr un diagnóstico precoz y mejorar el pronóstico de los pacientes con retinoblastoma. El dolor de ojos es uno de los síntomas del retinoblastoma.
