Overview
If left untreated, more than 50% of patients may continue to suffer from endocrine abnormalities such as growth hormone deficiency, growth retardation, hypopituitarism, and hypothyroidism, and may require lifelong hormonal replacement therapy. Common complications of germinoma include secondary cancers such as acute myeloid leukemia and radiation-induced brain neoplasms. Prognosis is generally excellent for germinomas, and the 5-year survival rate of patients with germinoma is approximately 70-90%. However, prognosis in general depends on the histological diagnosis and staging of the extent of disease.
Natural History
- Usually, patients with tumors in the pineal region tend to present with a brief history of symptoms compared with tumors of the basal ganglionic or suprasellar region, which presents a long history of symptoms including double vision related to tectal and aqueductal compression.[1]
- Approximately 35% of patients with suprasellar tumors will be asymptomatic for more than six months, and in these patients, the time between first symptom and diagnosis may be prolonged. Tumors arising in the suprasellar region often present with overt or subtle hormonal deficiencies and a prolonged prodrome often lasting months to years. A wide majority of patients may present with diabetes insipidus as the presenting finding; patients can usually compensate for antidiuretic hormone deficiency for months to years by drinking excessive amounts of fluid. This consequently leads to development of hormonal and visual changes as the tumor expands dorsally and compresses the optic chiasm. Symptoms related to endocrinopathy (delayed vertical growth, diabetes insipidus, etc.) are associated with delays in diagnosis of greater than 12 months, and are associated with higher incidences of disseminated disease.[2][3]
- In approximately 22% of cases metastasis has been noted at time of diagnosis.
- The presentation is often delayed with the tumors of the thalami and basal ganglia, with a larger tumor at diagnosis.
- Although germ cell tumors may be disseminated at the time of diagnosis, signs and symptoms of spinal cord or cerebral cortical involvement are uncommon, except for some infrequent cases of germinomas which arise in the basal ganglionic region or thalamus.[4][5][6][7][8][9][10]
Complications
- Patients with intracranial tumors located in the basal ganglia perform poorly compared with those who have tumors in the suprasellar and pineal regions; they have lower short-term retention of visual and verbal stimuli and full-scale IQs.
- Larger irradiation volume and dose effect the following functions of the brain adversely:[11]
- Intellectual functions
- Concept
- Executive function
- Memory
- Decline in neurocognitive function, and performance IQs
- Approximately more than 50% of patients may continue to suffer from endocrine abnormalities such as growth hormone deficiency, growth retardation, hypopituitarism, and hypothyroidism, and may require lifelong hormonal replacement therapy[12][13]
- Due to surgical resection of tumor or due surgical biopsies the following complications may occur:
- Poor performance in psychosocial skills
- Behavioral dysfunction
- Financial difficulties
- Lower KPS scores following surgery have been associated with impaired neurocognitive function
- Complications related to chemotherapy may develop
- The surgical morbidity associated with pineal-region tumors is approximately 2-5%. Patients may suffer from the following:
- Transient movement abnormalities of eyes
- Ataxia
- Cognitive dysfunction
- The other complications that may present in patients with intracranial germ cell tumors are following:
- Brain atrophy
- Multifocal encephalomalacia
- Leukoencephalopathy
- Focal necrosis
- Cerebrovascular occlusion
- The incidence of secondary cancer is approximately 6%, in patients with intracranial tumors. The risk of death due to malignancy is approximately 16%. Radiation therapy and chemotherapy may both promote the development of secondary cancers such as acute myeloid leukemia and radiation-induced brain neoplasms.[14][15][16][17][18][19][20][21]
Prognosis
The following two factors are of prognostic significance:
- Histological diagnosis
- Germinomas were associated with significantly longer survival than nongerminomatous GCT's
- Staging of the extent of disease
- Germ-cell tumors may infiltrate the hypothalamus (11%), or disseminate to involve the third ventricle (22%) and spinal cord (10%).[22]
- Generally, germinomas are associated with an excellent prognosis. Intracranial germinomas have a reported 90% survival to five years after diagnosis.[23] The 10-year survival of germinomas is 70%.
Based on the prognosis of the tumor, intracranial germ cell tumors may be classified into either good, intermediate, or poor prognosis. Pure germinomas carry a better prognosis than non germinomatous germ cell tumors (NGGCTs). Secreting germ cell tumors (GCTs) are generally considered to behave more aggressively and carry a poorer prognosis than nonsecreting germ cell tumors GCTs.[24][25]
