Dose Characteristics of Stereotactic Radiosurgery in High Energy Linear Accelerator Photon Beam
Tae Jin Choi, Ok Bae Kim
Radiat Oncol J. 1992;10(2):137-146.
Three-dimensional dose calculations based on CT images are fundamental to stereotactic radiosurgery for small intracranial tumor. In our stereotactic radiosurgery program, irradiations have been performed using the 6 MV photon beam of linear accelerator after stereotactic CT investigations of the target center through the beam's-eye view and the coordinates of BRW frame converted to that of radiosurgery. Also we can...

Ho Jun Lee, Tae Jin Choi, Ok Bae Kim
Radiat Oncol J. 1992;10(2):147-154.
It is ideal thing to compensate tissue deficit without skin contamination in curvatured irradiation field of high energy Photon beam. The 3-dimensional compensating technique utilizing tissue equivalent materials to ensure an adequate dose distribution and skin sparing effect was described. This compensator was made of paraffin(70%) and stearin wax (30%) compound. The parameters for evaluation of the effect on skin dose...
Dose Distribution for Eye Shielding Block in 6 MV Photon Beam Therapy
Kyung Ja Lee
Radiat Oncol J. 1992;10(2):155-162.
The eye lens is known to be radiosensitive organ and catarat can be induced by relatively low dose of radiation. In the treatment of head and neck tumors, shielding blocks are frequently used to minimize dose on sensitive organs. The shielding block, which is trade of high atomic number materials (cerrobend), produce significant dose perturbations in megavoltage photos beams. The...

Low Grade Astrocytoma-Need Postoperative Radiotherapy or Not?
Seong Eon Hong, Doo Ho Choi, Tae Sung Kim, Won Leem
Radiat Oncol J. 1992;10(2):171-180.
The precise role of radiotherapy for low grade gliomas including the optimal radiation dose and timing of treatment remains unclear. The information given by a retrosepctive analysis may be useful in the design of prospective randomized studies looking at radiation dose and time of surgical and radiotherapeutic treatment. The records of 56 patients (M:F=29:27) with histologically verified cerebral low grade...

Median follow-up period was 39 months. The 3 year actuarial survival rate of T1,T2 was 81% and 80%, respectively. Three patients(13%) shewed second malignant tumors and the site...
Complication of Intraoperative Radiation Therapy (IORT) in Gastric Cancer
Myung Se Kim, Sung Kyu Kim, Sung Kyo Song, Hong Jin Kim, Koing Bo Kwan, Heung Dae Kim
Radiat Oncol J. 1992;10(2):187-192.
Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and increse distant metastasis free survival. IORT is the modality which could increase local control without incressing complication, combined with curative operation. Eventhough we could achieve significant deacreased local failure by IORT and curative resection, it should not be committed...
