Definitive concurrent chemoradiotherapy in locally advanced pancreatic cancer
Yoo-Kang Kwak, Jong Hoon Lee, Myung-Ah Lee, Hoo-Geun Chun, Dong-Goo Kim, Young Kyoung You, Tae-Ho Hong, Hong Seok Jang
Radiat Oncol J. 2014;32(2):49-56.   Published online June 30, 2014
Purpose

Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer.

Materials and Methods

Medical records of 34 patients diagnosed with unresectable...

The association of rectal equivalent dose in 2 Gy fractions (EQD2) to late rectal toxicity in locally advanced cervical cancer patients who were evaluated by rectosigmoidoscopy in Faculty of Medicine, Chiang Mai University
Ekkasit Tharavichtikul, Pooriwat Meungwong, Taned Chitapanarux, Somvilai Chakrabandhu, Pitchayaponne Klunklin, Wimrak Onchan, Somsak Wanwilairat, Patrinee Traisathit, Razvan Galalae, Imjai Chitapanarux
Radiat Oncol J. 2014;32(2):57-62.   Published online June 30, 2014
Purpose

To evaluate association between equivalent dose in 2 Gy (EQD2) to rectal point dose and gastrointestinal toxicity from whole pelvic radiotherapy (WPRT) and intracavitary brachytherapy (ICBT) in cervical cancer patients who were evaluated by rectosigmoidoscopy in Faculty of Medicine, Chiang Mai University.

Materials and Methods

Retrospective study was designed for the patients with locally advanced cervical cancer, treated by radical radiotherapy from...

Patterns of failure and prognostic factors in resected extrahepatic bile duct cancer: implication for adjuvant radiotherapy
Tae Ryool Koo, Keun-Yong Eom, In Ah Kim, Jai Young Cho, Yoo-Seok Yoon, Dae Wook Hwang, Ho-Seong Han, Jae-Sung Kim
Radiat Oncol J. 2014;32(2):63-69.   Published online June 30, 2014
Purpose

To find the applicability of adjuvant radiotherapy for extrahepatic bile duct cancer (EBDC), we analyzed the pattern of failure and evaluate prognostic factors of locoregional failure after curative resection without adjuvant treatment.

Materials and Methods

In 97 patients with resected EBDC, the location of tumor was classified as proximal (n = 26) and distal (n = 71), using the junction of the...

Postoperative radiation therapy following the incomplete resection of a non-small cell lung cancer
Jaehyeon Park, Si Yeol Song, Su Ssan Kim, Sang-We Kim, Woo Sung Kim, Seung-Il Park, Dong Kwan Kim, Yong-Hee Kim, Jongmoo Park, Sang-wook Lee, Jong Hoon Kim, Seung Do Ahn, Eun Kyung Choi
Radiat Oncol J. 2014;32(2):70-76.   Published online June 30, 2014
Purpose

To review the results of postoperative radiation therapy (PORT) for residual non-small cell lung cancer (NSCLC) following surgical resection and evaluate multiple clinicopathologic prognostic factors.

Materials and Methods

A total of 58 patients, who completed scheduled PORT for positive resection margin, among 658 patients treated with PORT from January 2001 to November 2011 were retrospectively analyzed. Radiation therapy was started at 4...

Prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases
Jun Su Park, Hee Chul Park, Doo Ho Choi, Won Park, Jeong Il Yu, Young Suk Park, Won Ki Kang, Joon Oh Park
Radiat Oncol J. 2014;32(2):77-83.   Published online June 30, 2014
Purpose

To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases.

Materials and Methods

Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions.

Results

The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total...

Physics Contribution
Cardiac dose reduction with breathing adapted radiotherapy using self respiration monitoring system for left-sided breast cancer
KiHoon Sung, Kyu Chan Lee, Seung Heon Lee, So Hyun Ahn, Seok Ho Lee, Jinho Choi
Radiat Oncol J. 2014;32(2):84-94.   Published online June 30, 2014
Purpose

To quantify the cardiac dose reduction during breathing adapted radiotherapy using Real-time Position Management (RPM) system in the treatment of left-sided breast cancer.

Materials and Methods

Twenty-two patients with left-sided breast cancer underwent CT scans during breathing maneuvers including free breathing (FB), deep inspiration breath-hold (DIBH), and end inspiration breath-hold (EIBH). The RPM system was used to monitor respiratory motion, and the...

Case Reports
Aggressive clinical course of extramammary Paget disease after radiotherapy
Yunseon Choi, Won Park, Jeeyun Lee, Eun Yoon Cho, Goo-Hyun Moon
Radiat Oncol J. 2014;32(2):95-98.   Published online June 30, 2014

Extramammary Paget disease (EMPD) is a rare disease, especially in Asian populations. Surgical resection is considered the primary treatment option. Recently, radiotherapy has been suggested as an EMPD treatment, either as an alternative to surgical resection or in combination with surgical resection. This report reviewed a patient with EMPD who was treated with wide excision of the EMPD site followed...

Short-course hypofractionated radiochemotherapy for unresectable locally advanced cancer of the base of tongue: palliation only? A case report and short review of the literature
Maria-Aggeliki Kalogeridi, Vassilios Kouloulias, Anna Zygogianni, George Kyrgias
Radiat Oncol J. 2014;32(2):99-102.   Published online June 30, 2014

We present a case of unresectable cancer of the base of tongue treated with hypofractionated 3D conformal radiotherapy and concomitant chemotherapy. Based on the excellent tumour response in this radiotherapy regimen and international experience in short course treatments we shortly reviewed, we propose that this therapeutic approach could be considered in a curative setting for patients unsuitable for the a...
