Overview
If left untreated, retinoblastoma may progress to develop seeding in the eye, leading to retinal detachment, necrosis and invasion of the orbit, optic nerve invasion, and central nervous system invasion. The majority of untreated patients die of intracranial extension and disseminated disease within one year. Spontaneous regression of the tumor is a rare occurrence but may occur in a small number of cases. Common complications of retinoblastoma include metastasis, tumor recurrence, trilateral retinoblastoma, and subsequent neoplasms. Prognosis is generally good, and the survival rate of patients with retinoblastoma with treatment is approximately 95% in the United States.
Natural History
- Retinoblastoma usually first presents with leukocoria.[1]
- Left untreated, retinoblastoma may be deadly. The tumor will continue growing and filling the entire globe with subsequent metastasis.
- The tumor remains within the globe and curable within 3 to 6 months of its first presentation (leukocoria). Any delay in the diagnosis will decrease the survival rate.[2]
- Death may occur within one year of metastasis.
- Metastasis may occurs through four possible way:[3][4][5][6]
- Direct invasion of the central nervous system via the optic nerve.
- Through the subarachnoid space to the contralateral optic nerve
- Through the cerebrospinal fluid to the central nervous system
- Hematogenously to the lungs, bone, and brain.
- The tumor may also spread via lymphatic pathway if the tumor dispers anteriorly into the conjunctivae, eyelids, or extraocular tissue.
- Spontaneous regression of the tumor is a rare occurrence but may occur in a small number of cases.[7]
- Retinoblastoma is bilateral in 25%–35% of cases.[8]
Prognosis
- Those with heritable form of the disease have 50% risk of transmitting the mutation to their offspring.[9]
- The survival rate of the tumor varies according to different criteria including the stage of the tumor and even the geographic area of the patients.
- The overall 5-year survival rate increased over the years and was reported 97.3% from 2000 to 2012.[11]
- The 5-year survival rate also differs geographically and is higher in the United States than the 5-year survival rates reported in developing countries and regions.
- The survival rate is higher for unilateral involvement than the bilateral form of the tumor.
- It has been observed that survival rate varies depending following factors:
- Prognosis is generally good, and the survival rate of patients with retinoblastoma with treatment is approximately 95%, in the United States.[12]
- The overall prognosis of trilateral retinoblastoma is poor and patients usually die within the first year of the diagnosis.[13]
- Intraocular Classification of Retinoblastoma (ICRB) has been observed to have the ability to predict the outcome of chemotherapy:[14]
- Category A-C is associated with ≥90% chance to salvage the eye.
- Category D is associated with a 47% chance of eye salvage.
- Category E is excluded due to eye enucleation.
- Prognosis is usually poor with non-ocular tumor and it usually occurs in those who received radiation therapy for their primary retinoblastoma tumors.[15]
Complications
Complications of retinoblastoma
- Metastatic disease associates with poor prognosis.
- Several histopathologic factors has been associated with increased risk of metastasis. these include:[16]
- Presence of orbital invasion
- Retrolaminar invasion of optic nerve
- Scleral and extrascleral invasion
- Massive choroidal invasion
- Anterior segment involvement
- The most important prognostic factor are the involvement of optic nerve posterior to the lamina cribrosa and extrascleral spread of tumor into the orbit.
- Other elements with probable risk of tumor metastasis include:
- Massive choroidal invasion
- Tumor invasion into the anterior chamber
- Large tumor size with vitreous seeding
- Neovascularization of the iris
- Glaucoma
Recurrence of tumor
Trilateral retinoblastoma
- Trilateral retinoblastoma is a rare complication and more commonly affects those with bilateral disease who are less than 1 year of age.[17]
- Trilateral retinoblastoma is characterized by the combination of bilateral intraocular retinoblastoma and pineoblastoma, a primitive tumor of pineal gland.[18]
- Patients with this complication may remain asymptomatic and will be discovered incidentally by imaging studies or they may indicate signs of elevated intracranial pressure (ICP).
Subsequent neoplasms
- Children with germ-line mutation of RB1 gene are at elevated risk of secondary malignant tumors.[19]
- The most common secondary tumors include:
- The estimated risk of developing a secondary tumor is 20 times greater than the general population.
