PURPOSE: We collected the data of Science Citation Index (SCI) and SCI Expended (SCIE) papers written by the members of the Korean Society of Radiation Oncology (KOSRO) to analyze the current status and the future trend. MATERIALS AND METHODS: We searched the database of SCIE for the period from 1981 to 2011 at the Web of Knowledge site. Articles, reviews or proceedings written by KOSRO members as the first or corresponding authors were included. Search terms were the following combination of subject headings: therapeut radiol, radiat oncol, Korea. For National Cancer Center, combined search terms such as natl canc ctr, Korea and the names of faculties were applied. RESULTS: The total number of SCIE papers was 547. Numbers of the published papers in 1995, 2000, 2005, and 2010, were increased continuously, which was 2, 14, 40, and 83, respectively. The average impact factor was 2.9. The papers were published at the 134 different journals. The proportion of "International Journal of Radiation Oncology Biology Physics" was 23.4% of all the papers. The number and proportions of papers by subject categories were 87 (15.9%) in biology, 73 (13.3%) in physics and 387 (70.6%) in clinics. The papers of the top five institutions, based on the number of published papers, occupied 66.3%. CONCLUSION: The number of SCIE papers is increasing rapidly in the field of radiation oncology in Korea. To improve the quality of papers, multi-institutional retrospective or prospective randomized studies should be done for the common cancers in Korea.

Insufficiency fracture occurs when normal or physiological stress applied to weakened bone with demineralization and decreased elastic resistance. Recently, many studies reported the development of IF after radiation therapy (RT) in gynecological cancer, prostate cancer, anal cancer and rectal cancer. The RT-induced insufficiency fracture is a common complication during the follow-up using modern imaging studies. The clinical suspicion and knowledge the characteristic imaging patterns of insufficiency fracture is essential to differentiate it from metastatic bone lesions, because it sometimes cause severe pain, and it may be confused with bone metastasis.

A fistulous comunication between kidney and colon after trauma is rare and usually causes severe damage to kidney necessitating nephrectomy. Intrarenal aneruysm after trauma is also rare and its accurate diagnosis is important. Authors have experienced a reno-colic fistula and intrarenal aneruysm occured in a same patient afterpenetrating renal injury.

PURPOSE: To describe chronic rectal mucosal damage after pelvic radiotherapy (RT) for cervical cancer and correlate these findings with clinical symptoms and radiation dose. MATERIALS AND METHODS: Thirty-two patients who underwent pelvic RT were diagnosed with radiation-induced proctitis based on endoscopy findings. The median follow-up period was 35 months after external beam radiotherapy (EBRT) and intracavitary radiotherapy (ICR). The Vienna Rectoscopy Score (VRS) was used to describe the endoscopic findings and compared to the European Organization for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) morbidity score and the dosimetric parameters of RT (the ratio of rectal dose calculated at the rectal point [RP] to the prescribed dose, biologically effective dose [BED] at the RP in the ICR and EBRT plans, alpha/beta = 3). RESULTS: Rectal symptoms were noted in 28 patients (rectal bleeding in 21 patients, bowel habit changes in 6, mucosal stools in 1), and 4 patients had no symptoms. Endoscopic findings included telangiectasia in 18 patients, congested mucosa in 20, ulceration in 5, and stricture in 1. The RP ratio, BEDICR, BEDICR+EBRT was significantly associated with the VRS (RP ratio, median 76.5%; BEDICR, median 37.1 Gy3; BEDICR+EBRT, median 102.5 Gy3; p < 0.001). The VRS was significantly associated with the EORTC/RTOG score (p = 0.038). CONCLUSION: The most prevalent endoscopic findings of RT-induced proctitis were telangiectasia and congested mucosa. The VRS was significantly associated with the EORTC/RTOG score and RP radiation dose.

Breast cancer has become one of the most frequent malignancies among Korean women and the role of radiation therapy (RT) is expected to increase continuously. Current concepts in the treatment of breast cancer include a less radical surgery and the emergence of RT and systemic drug treatment. A surgery directed to minimize breast loss and RT to the whole breast has been the treatment of choice for early lesions. The use of whole breast irradiation (WBI) after the minimal breast surgery has been shown to significantly reduce the risk of recurrence in the affected breast and to increase the likelihood of long-term survival. Recently, there has been growing interest in the use of accelerated partial breast irradiation (APBI) as an alternative to WBI. APBI offers decreased overall treatment time and several advantages over WBI, including a decrease in the radiation dose delivered to uninvolved breast and adjacent organs. For the radiotherapy of breast cancer virtual simulation using the CT for three dimensional conformal RT has been widely used for external radiotherapy. The interstitial brachytherapy (insertion of radioactive source into the breast), balloon brachytherapy, and intraoperative electron therapy has been used for the APBI. Three dimensional radiotherapy including intensity modulated radiotherapy will be more widely used for breast cancer. RT fields are progressively reduced and APBI will be a realistic alternative in the future. CONCLUSION: The role of RT for treatment of breast cancer is important and the implementation of new RT technology will increase.

Vesicovaginal fistula is a uncommon status in the developed countries. In the past it was mostly by obstetric causes. But now a days, posthysterectomy fistulas are seen. Fistula is a discomfort to the patient because of urine leakage, odor, and its inconvenience. We have experienced one case of fistula after abdominal hysterectomy and have repaired it by Latzko partial colpocleisis. So we report a case with some references.

The interaction of radiation and 5-luorouracil (5-U) on mouse jejunal crypt cells was studied using the microcolony survival assay. 150mg/kg of 5-U was injected intraperitoneally 15 minutes before irradiation and 6 hours after irradiation. Jejunal crypt cells of mouse survived more when 5-U was given 15 minutes before irradiation than giving it 6 hours after irradiation. The mean lethal doses (Do) of each of irradiation alone group, 5-U injection group of 15 minutes preceding irradiation, and 5-U injection group of 6 hours post irradiation were. 135, 135, and 114 rad respectively. The dose effect factor (DEF) of each of 5-U injection groups of 15 minutes preceding irradiation and of 6 hours post irradiation were 1.13 and 1.27.
