Early changes in volume and non-enhanced volume of acoustic neurinoma after stereotactic gamma-radiosurgery.
نویسندگان
چکیده
The effectiveness of stereotactic gamma-radiosurgery for treating acoustic neurinoma was evaluated by measuring the volumes of the tumor, non-enhanced tumor, and cerebellar edema in 13 patients with acoustic neurinoma who were followed up for 9 to 15 months (median 12.7 mos) after treatment. The tumor volume and non-enhanced volume tended to reach a maximum after 6 months, and cerebellar edema volume after 9 months, then decreased gradually thereafter. Hearing loss tended to increase gradually, but involvement of the facial nerve was transient.

Quantitative tumor volumetric responses after Gamma Knife radiosurgery for meningiomas.
OBJECT The reported tumor control rates for meningiomas after stereotactic radiosurgery (SRS) are high; however, early imaging assessment of tumor volumes may not accurately predict the eventual tumor response. The objective in this study was to quantitatively evaluate the volumetric responses of meningiomas after SRS and to determine whether early volume responses are predictive of longer-term...
متن کاملRadiosurgery for vestibular schwannomas.
BACKGROUND Radiosurgery has been established as an important alternative to microsurgery. We report our experience with radiosurgery for tumor control and the complications of unilateral vestibular schwannomas. METHODS We reviewed our early experience regarding clinical presentation, management and outcomes in 45 patients with acoustic schwannomas who underwent gamma knife stereotactic radios...
متن کاملThe newly diagnosed vestibular schwannoma: radiosurgery, resection, or observation?
OBJECT Management recommendations for patients with smaller-volume or newly diagnosed vestibular schwannomas (< 4 cm(3)) need to be based on an understanding of the anticipated natural history of the tumor and the side effects it produces. The natural history can then be compared with the risks and benefits of therapeutic intervention using a minimally invasive strategy such as stereotactic rad...
متن کاملGamma knife radiosurgery for vestibular schwannomas.
Radiosurgery is a surgical procedure associated with minimal functional morbidity and allows patients to return rapidly to their previous level of activity. Most tumors regress in volume with extended follow-up, and the rare occurrence of tumor growth after radiosurgery seems to occur early. Similarly, cranial neuropathy or other neurologic symptoms after irradiation occur within the first few ...
متن کاملGamma knife radiosurgery after stereotactic aspiration for large cystic brain metastases.
OBJECTIVE Several treatment options have proven effective for metastatic brain tumors, including surgery and stereotactic radiosurgery. Tumors with cystic components, however, are difficult to treat using a single method. We retrospectively assessed the outcome and efficacy of gamma knife radiosurgery (GKRS) for cystic brain metastases after stereotactic aspiration of cystic components to decre...
