Clinical Investigation
Clinical predictive factors of pathologic tumor response after preoperative chemoradiotherapy in rectal cancer
Chi Hwan Choi, Won Dong Kim, Sang Jeon Lee, Woo-Yoon Park
Radiat Oncol J. 2012;30(3):99-107.   Published online September 30, 2012
Purpose

The aim of this study was to identify clinical predictive factors for tumor response after preoperative chemoradiotherapy (CRT) in rectal cancer.

Materials and Methods

The study involved 51 patients who underwent preoperative CRT followed by surgery between January 2005 and February 2012. Radiotherapy was delivered to the whole pelvis at a dose of 45 Gy in 25 fractions, followed by a boost...

Postoperative radiotherapy for endometrial cancer
Eun Cheol Choi, Jin Hee Kim, Ok Bae Kim, Sang Jun Byun, Seung Gyu Park, Sang Hoon Kwon
Radiat Oncol J. 2012;30(3):108-116.   Published online September 30, 2012
Purpose

To investigate the prognostic factors and effectiveness of postoperative radiotherapy alone for endometrial carcinoma.

Materials and Methods

Sixty four patients with stage I-III endometrial cancer (EC) treated with postoperative radiotherapy alone between January 1989 and December 2008 at the Keimyung University Dongsan Medical Center were chosen for the present study. Typically, total hysterectomy, salpingo-oophorectomy and lymphadenectomy were performed on the patient's pelvis....

Negative impact of pretreatment anemia on local control after neoadjuvant chemoradiotherapy and surgery for rectal cancer
Hyebin Lee, Hee Chul Park, Won Park, Doo Ho Choi, Young-Il Kim, Young Suk Park, Joon Oh Park, Ho-Kyung Chun, Woo-Yong Lee, Hee Cheol Kim, Seong Hyeon Yun, Yong Beom Cho, Yoon Ah Park
Radiat Oncol J. 2012;30(3):117-123.   Published online September 30, 2012
Purpose

Although anemia is considered to be a contributor to intra-tumoral hypoxia and tumor resistance to ionizing radiation in cancer patients, the impact of pretreatment anemia on local control after neoadjuvant concurrent chemoradiotherapy (NACRT) and surgery for rectal cancer remains unclear.

Materials and Methods

We reviewed the records of 247 patients with locally advanced rectal cancer who were treated with NACRT followed by...

Treatment outcome in patients with triple negative early stage breast cancers compared with other molecular subtypes
Ja Young Kim, Sei-Kyung Chang, Heily Park, Bo-Mi Lee, Hyun Soo Shin
Radiat Oncol J. 2012;30(3):124-131.   Published online September 30, 2012
Purpose

To determine whether triple negative (TN) early stage breast cancers have poorer survival rates compared with other molecular types.

Materials and Methods

Between August 2000 and July 2006, patients diagnosed with stage I, II early stage breast cancers, in whom all three markers (estrogen receptor, progesterone receptor, and human epidermal growth factor receptor [HER]-2) were available and treated with modified radical mastectomy...

Nutritional status of patients treated with radiotherapy as determined by subjective global assessment
Woong Sub Koom, Seung Do Ahn, Si Yeol Song, Chang Geol Lee, Sung Ho Moon, Eui Kyu Chie, Hong Seok Jang, Young-Taek Oh, Ho Sun Lee, Ki Chang Keum
Radiat Oncol J. 2012;30(3):132-139.   Published online September 30, 2012
Purpose

The purpose of this prospective multi-institutional study was to evaluate the nutritional status of patients undergoing radiotherapy (RT) for treatment of head and neck, lung, or gastrointestinal cancer.

Materials and Methods

A total of 1,000 patients were enrolled in this study at seven different hospitals in Seoul, Korea between October 2009 and May 2010. The nutritional status of patients after receiving 3...

Concurrent chemoradiotherapy for elderly patients with stage III non-small cell lung cancer
Ki Mun Kang, Bae Kwon Jeong, In Bong Ha, Gyu Young Chai, Gyeong Won Lee, Hoon Gu Kim, Jung Hoon Kang, Won Seob Lee, Myoung Hee Kang
Radiat Oncol J. 2012;30(3):140-145.   Published online September 30, 2012
Purpose

Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC.

Materials and Methods

Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was...

Physics Contribution
The impact of beam angle configuration of intensity-modulated radiotherapy in the hepatocellular carcinoma
Sung Hoon Kim, Min Kyu Kang, Ji Woon Yea, Sung Kyu Kim, Ji Hoon Choi, Se An Oh
Radiat Oncol J. 2012;30(3):146-151.   Published online September 30, 2012
Purpose

This treatment planning study was undertaken to evaluate the impact of beam angle configuration of intensity-modulated radiotherapy (IMRT) on the dose of the normal liver in hepatocellular carcinoma (HCC).

Materials and Methods

The computed tomography datasets of 25 patients treated with IMRT for HCC were selected. Two IMRT plans using five beams were made in each patient; beams with equidistance of 72°...
