Direct chemotherapy for retinoblastoma eye tumor
Cancer
Cancer is a disease that begins with the abnormal proliferation of the body’s cells. Normally, cells in the body follow a regulated program where old cells die and are replaced by new ones.
Sometimes, this natural process becomes disrupted, and worn-out cells fail to die off, leading to the formation of a mass that can develop into a malignant tumor or cancer. Cancer exists in various forms.
Retinoblastoma Tumor
Retinoblastoma is a rare cancer that affects the retina of the eye. It predominantly occurs in children, infants, and occasionally in fetuses before birth. Genetic and hereditary factors play a significant role in the development of this type of tumor. If retinoblastoma is diagnosed in a timely manner, the treatment outcomes are highly favorable.
Symptoms of Retinoblastoma Tumor
Eye reflex (like a cat’s eye):
This phenomenon often appears when photographing a child’s eye and resembles a glimmer or flash in the eye.
Strabismus (Eye Misalignment):
Another symptom of this tumor is strabismus (crossed eyes), which appears suddenly.
Redness and inflammation of the eye:
Most patients with retinoblastoma tumors experience symptoms such as redness and inflammation of the eye, which may resemble an allergy or infection. Other symptoms include changes in iris color, reduced vision, and pupil enlargement, all of which can indicate the presence of this type of tumor.
Treatment of Retinoblastoma Tumor:
After consulting a specialist and confirming this type of tumor, appropriate treatment methods are recommended.

Chemotherapy
Direct arterial chemotherapy for the tumor
In this method, the chemotherapy drug is directly delivered into the blood vessel supplying the retinoblastoma tumor in a larger volume. A specialized catheter, guided by imaging equipment, is inserted through the right groin into the ophthalmic artery of the eye. Once the catheter’s position is confirmed, the chemotherapy drug mixture is slowly injected. This procedure is performed under general anesthesia. After the injection is completed, the catheter is removed from the groin, and the incision site is compressed manually to prevent bleeding from the groin area.

Frequently Asked Questions
How is direct chemotherapy for retinoblastoma performed?
In this method, the chemotherapy drug is administered directly into the artery supplying the eye through a delicate catheter. This ensures the drug reaches the tumor at a high concentration while simultaneously minimizing systemic side effects.
What is the advantage of this method compared to general chemotherapy?
Due to the targeted administration of the drug into the eye’s blood vessels, the effectiveness of the treatment has increased, and systemic side effects such as hair loss or severe bone marrow suppression occur less frequently.
Can this method help preserve the eye?
In many cases, this technique helps shrink or control the tumor and increases the likelihood of preserving the eyeball and vision compared to more invasive methods.
