1.An 87-year-old patient with repeated oligorecurrences over six years whose disease were treated with radiotherapy alone.
Radiation Oncology Journal 2014;32(4):266-271
In the clinical state of oligometastases or oligorecurrence, a transitional state between localized and widespread systemic disease, local control of the disease may yield improved systemic control. Radiotherapy may be a good means for controlling oligometastatic tumors, particularly in very old patients for whom surgery may be infeasible. A combination of systemic therapy and local therapy is necessary to prevent systemic progression. Some kinds of cancers found in the elderly are known to be somewhat indolent for systemic progression. So, for very old patients who refuse or cannot tolerate chemotherapy, the use of radical radiotherapy alone to treat oligorecurrences may be very helpful. We successfully treated an 87-year-old patient who had been diagnosed with oligorecurrences three times over six years with radiotherapy alone. The patient is now, about four years after his first radiotherapy for liver metastasis, alive without any evidence of cancer and with fully active performance status.

2.Linear Accelerator Radiosurgery for Trigeminal Neuralgia: Case Report.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2006;24(2):144-148
Trigeminal neuralgia is defined as an episodic electrical shock-like sensation in a dermatomal distribution of the trigeminal nerve. When medications fail to control pain, various procedures are used to attempt to control refractory pain. Of available procedures, stereotactic radiosurgery is the least invasive procedure and has been demonstrated to produce significant pain relief with minimal side effects. Recently, linear accelerators were introduced as a tool for radiosurgery of trigeminal neuralgia beneath the already accepted gamma unit. Author have experienced one case with trigeminal neuralgia treated with linear accelerator. The patient was treated with 85 Gy by means of 5 mm collimator directed to trigeminal nerve root entry zone. The patient obtained pain free without medication at 20 days after the procedure and remain pain free at 6 months after the procedure. He didn't experience facial numbness or other side effects.

3.Chromosomal Aberration in Fractionated Radiotherapy.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 1998;16(2):115-123
PURPOSE: This study was tried to evaluate the effect of the partial body fractionated irradiation on the frequency of chromosomal aberration. MATERIALS AND METHODS: In three patients with uterine cervix carcinoma, chromosomal aberrations were analyzed during fractionated external beam radiotherapy. Radiation field included whole pelvis and total dose was 5040 cGy in 28 fractions. RESULTS: The values of the frequency of dicentrics and rings (Ydr) in pre- irradiated peripheral lymphocytes in three patients were 0.0060, 0.0000, and 0.0029, respectively. The frequency of dicentrics and rings, estimated during the course of radiotherapy, increased with radiation dose and best fitted to the linear equation, Ydr=7.31x10(-5) D(cGy)+1.45x10(-2). The frequency of dicentrics and rings among the cells with dicentric and/or ring (Qdr) also showed increasing tendency and best fitted to the linear equation, Qdr= 1.01x10(-4) D(cGy)+1.04. CONCLUSION: Ydr increased linearly with radiation dose in the dose range of our study, and Qdr showed increasing tendency with dose.

The Journal of the Korean Society for Therapeutic Radiology and Oncology 2001;19(2):136-141
PURPOSE: To evaluate the significance of serum SCC for the monitoring of treatment response and the early detection of distant metastasis during radiotherapy (RT). MATERIALS AND METHODS: In 13 patients with histologically proven primary squamous cell carcinoma of uterine cervix, serum SCC values were checked in pre-RT point, weekly during RT, and in post-RT point. RESULTS: In 4 of 13 cases, metastasis appeared at the end of external RT, so that intracavitary radiation couldn't be performed. Of these 4 cases, 3 with elevated pre-RT SCC level, who resulted in lung metastasis on chest PA at the end of external RT showed decreased post-RT SCC value despite of metastasis. Of all 10 cases with elevated pre-RT SCC value (including 3 with metastasis at the end of external RT), SCC value was higher than pre-RT value in 7 at 9 Gy and the difference was statistically significant. At 18 Gy, SCC was higher in 4 and lower in 6 than pre-RT value. After 18 Gy, SCC value decreased continuously to the end of RT in all 10 cases. CONCLUSION: During RT, SCC value increased initially at 9 Gy. To 18 Gy, SCC value decreased to the nearly same with pre-RT value. After 18 Gy, to the end of RT, SCC value decreased continuously and normalized in completely responded cases. In cases with appearance of lung metastasis, SCC value also decreased with the disappearance of main mass of uterine cervix despite of metastasis.

The Journal of the Korean Society for Therapeutic Radiology and Oncology 1999;17(1):30-35
PURPOSE: To evaluate the significance of squaous cell carcinoma antigen (SCC) and carcinoembryonic anti antigen (CEA) as tumor markers in uterine cervix carcinoma. MATERIALS AND METHODS: In 22 patients with histologically proven primary squamous cell carcinoma of uterine cervix, tumor volume was checked either by using MRI (in 20 patients) or ultrasound (in 2 patients)or ultrasound (in 2 partients). Pre-treatment serum SCC levels were checked in 22 patients and CEA levels in 21 patients. Ather curative radiotherapy, post-treatment SCC and CEA were checked reqularly. RESULTS: SCC was raised in 68.2% and CEA was raised in 19.0% before treatment. The coefficinoma of correlation between tumor volume and pre-reatment SCC was 0.59382 when one extremely deviated case was excluded . And there was no correlation between tumor volume and CEA. After the treatment , SCC was raised in 9.1% and CEA. After the raise of SCC was associated with clinical relapse or persistence of disease. The specificity of raised SCC level in association with recurrent or persistent disease was 93.8%. The sencificity in association with recurrent or persistent disease was 100%. The positive predictive values was 85.7%. The median lead time for recurrence was 1.2 months. CONCLUSION: Both SCC and CEA were good tumor for monitoring treatment effect in patints with raised pre-treatment levels. But the sensitivity of pretreatment CEA was low, while that of pretreatment SCC was high. And there was no additional gain by adding CEA measurements to SCC measurements.

The Journal of the Korean Society for Therapeutic Radiology and Oncology 1998;16(4):477-484
PURPOSE: Radiation proctitis and radiation cystitis are frequent and problematic late complications in patients treated with radiation for the uterine cervix cancer. Authors tried to find out the better patient's position in high dose rate intracavitary radiation to reduce the radiation dose of bladder and rectum. MATERIALS AND METHODS: In 13 patients, Foley catheters were inserted to patients' bladder and rectum and were ballooned with radioopaque dye. After insertion of a tandem and two ovoids, semi-orthogonal anteroposterior and lateral films were taken in both lithotomy and supine position. The rectal point and bladder point were defined according to the criteria recommended in the ICRU Report 38 with modification. Using these films, all patients' bladder and rectal dose were calculated in both positions (the radiation dose of A point was set to 400 cGy). And also, the distance of bladder and rectum from uterine cervical os was calculated in both positions. RESULTS: The average radiation dose of rectum was 240.7 cGy in lithotomy position and 278.3 cGy in supine position, and the average radiation dose of bladder was 303.5 cGy in lithotomy position and 255.8 cGy in supine position. After the paired t-test, the radiation dose of rectum in lithotomy position was marginally significantly lower than that in supine position, while the radiation dose of bladder in lithotomy position was significantly higher than that in supine position. On the other hand, the average distance between rectum and cervical os was 35.2 mm in lithotomy position and 32.3 mm in supine position. and the average distance between bladder and cervical os was 30.4 mm in lithotomy position and 34.0 mm in supine posi-tion. After the paired t-test, the distance between rectum and cervical os in lithotomy position was significantly longer than that in supine position, while the distance between bladder and cervical os in lithotomy position was significantly shorter than that in supine position. CONCLUSION: The radiation dose of bladder can be reduced in supine position and the radiation dose of rectum can be reduced in lithotomy position, so we can choose appropriate position in each patient.

8.A Case Report of a Gastric Cancer Patient with a Good Quality of Life after Radiotherapies to 17 Metastases for 4 Years.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2011;29(2):127-133
Five and half years ago, a 45-year-old female metastatic gastric cancer patient underwent a metastatectomy and chemotherapy. Over the last 4 years and 2 months, she received radiotherapy for every new distant metastasis with intermittent TS-1 oral chemotherapy. She received 8 courses of radiotherapy at 17 metastatic sites for more than 4 years. Metastatic sites which received a curative radiation dose achieved and maintained local control. The patient is now 51 years of age and lives without difficulty in performing her daily activities.

9.A Bile Duct Cancer Patient Whose Stent Shifted Significantly Over the Course of External Beam Radiotherapy.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2011;29(2):121-126
The author reports a bile duct cancer patient whose stent shifted significantly from right to left over the course of radiotherapy. The 80-year-old female patient had a short stature with thoracic kyphosis and mutiple spinal compression fractures. She was also emaciated and very lean. By comparing the weekly scanned computed tomography images, the author found her stent to have shifted by more than 4 cm from right to left over the course of external beam radiotherapy. The results of this case study suggest that for a very lean and emaciated kyphotic bile duct cancer patient, the possibility of large interfractional movement of the bile duct or stent during radiotherapy should be considered.

10.Long Term Follow Up Results of Serum Squamous Cell Carcinoma Antigen Level in Uterine Cervix Cancer Treated by Radiotherapy.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2003;21(4):283-290
PURPOSE: To evaluate the long term significance of the squamous cell carcinoma (SCC) antigen (Ag) as a tumor marker in uterine cervix carcinoma. MATERIALS AND METHODS: The SCC antigen levels of pre-radiotherapy and serial post-radiotherapy serum were analyzed in 48 patients who received radiotherapy with histologically proven primary SCC of the uterine cervix. RESULTS: Pre-radiotherapy SCC Ag level was high (>or=2 ng/ml) at 79.2%. After the treatment, the SCC Ag level was significantly decreased. The SCC Ag level measured at about 3 months after radiotherapy was high at 23.0%. In further follow up measurements, a rise of the SCC Ag to a high level was well associated with clinical relapse. The specificity of the elevated SCC Ag level in association with recurrent or persistent disease was 100%, and the sensitivity was 85.7%. In 3 of 4 lung metastasis cases, lung lesions were detected in chest PA before elevation of the SCC Ag level. The median lead time of the high SCC Ag level to clinical recurrence was 4 months. CONCLUSION: SCC Ag was a good tumor marker for monitoring treatment effect in patients with increased pre-treatment levels except in case of early lung metastasis. Elevation of the SCC Ag level after radiotherapy accurately predicted the treatment failure with lead time of 4 months. But, in early lung metastasis cases, the SCC level may be normal temporarily. Thus, chest PA should be checked to evaluate the presence of lung metastasis.
