Review Article
Insufficiency fracture after radiation therapy
Dongryul Oh, Seung Jae Huh
Radiat Oncol J. 2014;32(4):213-220.   Published online December 30, 2014

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...

Clinical Investigations
Vertebral compression fractures after spine irradiation using conventional fractionation in patients with metastatic colorectal cancer
Woo Joong Rhee, Kyung Hwan Kim, Jee Suk Chang, Hyun Ju Kim, Seohee Choi, Woong Sub Koom
Radiat Oncol J. 2014;32(4):221-230.   Published online December 30, 2014
Purpose

To evaluate the risk of vertebral compression fracture (VCF) after conventional radiotherapy (RT) for colorectal cancer (CRC) with spine metastasis and to identify risk factors for VCF in metastatic and non-metastatic irradiated spines.

Materials and Methods

We retrospectively reviewed 68 spinal segments in 16 patients who received conventional RT between 2009 and 2012. Fracture was defined as a newly developed VCF or...

Prediction of response by FDG PET early during concurrent chemoradiotherapy for locally advanced non-small cell lung cancer
Suzy Kim, So Won Oh, Jin Soo Kim, Ki Hwan Kim, Yu Kyeong Kim
Radiat Oncol J. 2014;32(4):231-237.   Published online December 30, 2014
Purpose

To evaluate the predictive value of the early response of 18F-flurodeoxyglucose positron emission tomography (FDG PET) during concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (NSCLC).

Materials and Methods

FDG PET was performed before and during CCRT for 13 NSCLC patients. Maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)...

Clinical outcome of high-dose-rate interstitial brachytherapy in patients with oral cavity cancer
Sung Uk Lee, Kwan Ho Cho, Sung Ho Moon, Sung Weon Choi, Joo Yong Park, Tak Yun, Sang Hyun Lee, Young Kyung Lim, Chi Young Jeong
Radiat Oncol J. 2014;32(4):238-246.   Published online December 30, 2014
Purpose

To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer.

Materials and Methods

Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using 192Ir between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment and in five patients as salvage treatment for recurrence after the...

Is neoadjuvant androgen deprivation therapy beneficial in prostate cancer treated with definitive radiotherapy?
Keun-Yong Eom, Sung W Ha, Eunsik Lee, Cheol Kwak, Sang Eun Lee
Radiat Oncol J. 2014;32(4):247-255.   Published online December 30, 2014
Purpose

To determine whether neoadjuvant androgen deprivation therapy (NADT) improves clinical outcomes in patients with prostate cancer treated with definitive radiotherapy.

Materials and Methods

We retrospectively reviewed medical records of 201 patients with prostate cancer treated with radiotherapy between January 1991 and December 2008. Of these, 156 patients with more than 3 years of follow-up were the subjects of this study. The median...

Physics Contribution
In vivo verification of regional hyperthermia in the liver
Jae Myoung Noh, Hye Young Kim, Hee Chul Park, So Hyang Lee, Young-sun Kim, Saet-Byul Hong, Ji Hyun Park, Sang Hoon Jung, Youngyih Han
Radiat Oncol J. 2014;32(4):256-261.   Published online December 30, 2014
Purpose

We performed invasive thermometry to verify the elevation of local temperature in the liver during hyperthermia.

Materials and Methods

Three 40-kg pigs were used for the experiments. Under general anesthesia with ultrasonography guidance, two glass fiber-optic sensors were placed in the liver, and one was placed in the peritoneal cavity in front of the liver. Another sensor was placed on the skin...

Case Reports
Radiation recall dermatitis induced by tamoxifen during adjuvant breast cancer treatment
Jiyoung Rhee, Gwi Eon Kim, Chang Hyun Lee, Jung-Mi Kwon, Sang-Hoon Han, Young Suk Kim, Woo-Kun Kim
Radiat Oncol J. 2014;32(4):262-265.   Published online December 30, 2014

Tamoxifen and radiotherapy are used in breast cancer treatment worldwide. Radiation recall dermatitis (RRD), induced by tamoxifen, has been rarely reported. Herein, we report a RRD case induced by tamoxifen. A 47-year-old woman had a right quadrantectomy and an axillary lymph node dissection due to breast cancer. The tumor was staged pT2N0; it was hormone receptor positive, and human epidermal...

An 87-year-old patient with repeated oligorecurrences over six years whose disease were treated with radiotherapy alone
Hyong Geun Yun
Radiat Oncol J. 2014;32(4):266-271.   Published online December 30, 2014

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...
