[Treatment outcomes in patients with central nervous system germinoma (neuro-ophthalmic aspects)]

The analyze the neuro-ophthalmic outcomes in patients with pineal and suprasellar germinoma after complex treatment.

There were 125 patients (88 males, 37 females) with primary CNS germinoma for the period 2008-2017. All patients were divided into 3 groups depending on the tumor localization: pineal area - 62 patients, suprasellar neoplasm - 38 patients, bifocal germinoma - 25 patients. Treatment was performed in accordance with the «Germinoma-2008» protocol. Tumors were histologically patients (partial - 32 cases, subtotal - 16 cases). Surgery was followed by postoperative chemotherapy and stereotactic radiotherapy. The results were evaluated by neuro-ophthalmological examination at all stages of complex treatment.

Pineal germinoma resulted oculomotor and pupillary disorders (58 patients - 94%) and papilledema. The last one completely regressed under the treatment. Partial reduction of oculomotor and pupillary abnormalities occurred throughout chemotherapy (6 patients - 10%). More than half of patients (n=24, 63%) with suprasellar germinoma had visual impairment. Improvement of visual functions including severe visual disturbance was observed in 14 patients (58%). Predominantly, functional recovery occurred under chemotherapy (12 patients - 86%). Bifocal germinoma was followed by various combinations of oculomotor, pupillary and/or visual impairments. We observed regression of only mild visual disorders. Stereotactic radiotherapy did not ensure any changes in neuro-ophthalmic symptoms in all groups.
