Comparison of conventional external radiotherapy and stereotactic radiotherapy in the treatment of pituitary adenoma.

Objective: To compare the results of pituitary adenoma treated with conventional external beam radiotherapy (EBRT) versus stereotactic radiosurgery and stereotactic radiotherapy (SRS/SRT).

Method And Material: Data of patients with pituitary adenoma treated at Radiotherapy and Oncology unit, Ramathibodi Hospital between 1990 from 2003 were retrospectively collected and analyzed. Twenty-two patients were treated with EBRT and 51 patients were treated with SRS/SRT.

Stereotactic radiation therapy for optic nerve sheath meningioma; an experience at Ramathibodi Hospital.

Objective: To evaluate results of stereotactic radiotherapy for the treatment of optic nerve sheath meningioma (OM) at Ramathibodi Hospital.

Material And Method: Twelve patients with primary OM were treated with stereotactic radiation between 1998 and 2005. Five patients underwent surgery and had no light perception before radiation.

Fractionated stereotactic radiotherapy for bilateral vestibular schwannomas associated with neurofibromatosis type 2: early experiences in Ramathibodi Hospital.

Purpose: To evaluate the rates of tumor control and useful hearing preservation in patients with bilateral vestibular schwannomas (VSs) associated with neurofibromatosis type 2 (NF-2) treated with fractionated stereotactic radiotherapy (FSRT).

Material And Method: From August 1998--December 2002 there were 5 patients with NF-2 who underwent FSRT (Linac-based system) for bilateral CP angle tumors. Median age was 28 (18-47) years.

Early neurological complications after stereotactic radiosurgery/radiotherapy.

Objective: To evaluate the neurological complications after stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT).

Material And Method: The Ramathibodi Radiosurgery Unit started its service in August 1997, using the linear-accelerator based system. There were 144 patients treated from August 1997 to October 1999.
