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

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.
    • Regarding the variable accessibility of patients to the resources, it may range from < 30% in low and middle income societies to > 90% developped contries.[10]
  • 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:
    • Laterality of the tumor
    • Age at the time of diagnosis
    • Decade of diagnosis
  • However, the prognosis is far less in case of eye salvage and depends on the stage of the tumor at the time of diagnosis.
  • The survival for nonpineal trilateral retinoblastoma is 57 percent.
  • The prognosis for vision in children with bilateral retinoblastoma depends upon the effectiveness of therapy and extent of tumor involvement. [19]
  • The prognosis for vision in the unaffected eye of children with unilateral retinoblastoma is excellent.
  • Given the poor prognosis of trilateral retinoblastoma and the short interval between the diagnosis of retinoblastoma and the occurrence of trilateral disease, routine neuroimaging could potentially detect most cases within 2 years of first diagnosis.
  • Prognosis depends on stage and grade of retinoblastoma.[21] Children who have a lower grade of retinoblastoma or a well-differentiated tumor have a more favorable prognosis than children with a higher grade or poorly differentiated tumor.
MRI component Features
Grade 1
  • Well differentiated or low grade – slow growing, less likely to spread
Grade 2
  • Moderately well differentiated or moderate grade
Grade 3
  • Poorly differentiated or high grade – tend to grow quickly, more likely to spread
Grade 4
  • Undifferentiated or high grade – tend to grow very quickly, likely to spread

The features associated with poor prognosis in retinoblastoma include:[22]

  • History of intraocular surgery, which may inadvertently contribute to vitreous seeding or, more importantly, to extraocular spread[27][28]
  • Use of external beam radiotherapy, which contributes to the subsequent development of secondary malignancies, particularly in patients with the heritable form of the disease[29][30][31]
  • Intraocular Classification of Retinoblastoma (ICRB) has been observed to have the ability to predict the outcome of chemotherapy:[35]
    • 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.

Complications

Complications of retinoblastoma

Metastasis

  • Metastatic disease associates with poor prognosis.
  • Several histopathologic factors has been associated with increased risk of metastasis. these include:[36]
    • 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 retinnoblastoma

  • Trilateral retinoblastoma is a well-recognized syndrome that occurs in 5% to 15% of patients with heritable retinoblastoma and is defined by the development of an intracranial midline neuroblastic tumor, which typically develops between the ages of 20 and 36 months.[37] Approximately 5% to 10% of children with heritable retinoblastoma develop pineal gland cysts detected by MRI; these cyst abnormalities must be distinguished from the pineoblastoma that typically defines trilateral retinoblastoma.
  • Subsequent neoplasms
    • Patients with retinoblastoma have a high risk of developing subsequent neoplasms. Osteogenic or soft tissue sarcomas are the common subsequent neoplasms that develop in children.[38][29][39][40][41][42] Factors that influence the risk of having subsequent neoplasms include:
      • Heritable retinoblastoma- There is increased risk of developing secondary primary tumors, including osteogenic sarcoma, soft tissue sarcomas (particularly leiomyosarcoma) and malignant melanoma in patients with the genetic abnormality associated with heritable forms of retinoblastoma.[43][38][29][44][39][40]
      • Past treatment of retinoblastoma with radiation therapy.[37]
      • Age at time of radiation therapy- The risk of subsequent neoplasms appears to be dependent on the patient's age at the time that external-beam radiation therapy is administered, especially in children younger than 12 months, and the histopathologic types of subsequent neoplasms may be influenced by age.[37]
      • Previous subsequent neoplasms- Those who survive subsequent neoplasms are at a sevenfold increased risk for developing another subsequent neoplasm.[39] An additional threefold increase in risk is seen for patients treated with radiation therapy.[45]

Complications of retinoblastoma therapy

  • Potential complications of enucleation include scleral perforation with seeding of tumor cells into the orbit.
