One-Week versus Two-Week Chemoradiotherapy Followed by Curative Surgery in Rectal Cancer: Long-Term Comparative Pooled Analysis of Two Prospective Multicenter Phase II Trials: Soo-Yoon Sung, Dae Yong Kim, Hong Seok Jang, Tae Hyun Kim, Hee Chul Park, Eui Kyu Chie, Taek-Keun Nam, Sung Hwan Kim, Jong Hoon Lee; Cancer Res Treat. 2023;55(3):918-926. Published online February 27, 2023; DOI: https://doi.org/10.4143/crt.2022.1646

Abstract PDF PubReader ePub: Purpose
The optimal short-course chemotherapeutic regimen for rectal cancer has not been clearly defined until now. KROG 10-01 and KROG 11-02 prospective trials investigated the efficacy and safety of 1- and 2-week chemoradiotherapy (CRT), respectively.
Materials and Methods
Patients eligible for KROG 10-01 and KROG 11-02 involved those with clinical T3-4N0-2M0 rectal cancers. They received preoperative CRT and total mesorectal excision. Patients in KROG 10-01 received radiation of 25 Gy in 5 fractions during 1 week with 5-fluorouracil/leucovorin. Patients in KROG 11-02 received radiation of 33 Gy in 10 fractions for 2 weeks with oral capecitabine.
Results
A total of 150 patients consisting of 70 patients from KROG 10-01 and 80 patients from KROG 11-02 were collectively analyzed. With a median follow-up time of 89.2 months, the 5-year overall survival rate was 86.5% in 1-week CRT and 85.3% in 2-week CRT (p=0.841). The 5-year recurrence-free survival rate was 83.5% in 1-week CRT and 77.1% in 2-week CRT (p=0.448). One patient (1.4%) in 1-week CRT and 11 patients (13.8%) in 2-week CRT exhibited pathologic complete regression (ypT0N0M0) after radiotherapy (p=0.006). One-week CRT had significantly higher acute hematologic (12.8% vs. 3.8%, p=0.040) and nonhematologic (38.6% vs. 16.3%, p=0.002) toxicity than 2-week CRT.
Conclusion
Both 1- and 2-week schedules of CRT showed favorable survival outcomes after 7 years of follow-up. But, 2-week course achieved more increased tumor response and decreased acute toxicity than 1-week course.

Optimal Definition of Biochemical Recurrence in Patients Who Receive Salvage Radiotherapy Following Radical Prostatectomy for Prostate Cancer: Sung Uk Lee, Jae-Sung Kim, Young Seok Kim, Jaeho Cho, Seo Hee Choi, Taek-Keun Nam, Song Mi Jeong, Youngkyong Kim, Youngmin Choi, Dong Eun Lee, Won Park, Kwan Ho Cho; Cancer Res Treat. 2022;54(4):1191-1199. Published online December 7, 2021; DOI: https://doi.org/10.4143/crt.2021.985

Abstract PDF Supplementary Material PubReader ePub

Purpose
This study proposed the optimal definition of biochemical recurrence (BCR) after salvage radiotherapy (SRT) following radical prostatectomy for prostate cancer.
Materials and Methods
Among 1,117 patients who had received SRT, data from 205 hormone-naïve patients who experienced post-SRT prostate-specific antigen (PSA) elevation were included in a multi-institutional database. The primary endpoint was to determine the PSA parameters predictive of distant metastasis (DM). Absolute serum PSA levels and the prostate-specific antigen doubling time (PSA-DT) were adopted as PSA parameters.
Results
When BCR was defined based on serum PSA levels ranging from 0.4 ng/mL to nadir+2.0 ng/mL, the 5-year probability of DM was 27.6%-33.7%. The difference in the 5-year probability of DM became significant when BCR was defined as a serum PSA level of 0.8 ng/ml or higher (1.0-2.0 ng/mL). Application of a serum PSA level of ≥ 0.8 ng/mL yielded a c-index value of 0.589. When BCR was defined based on the PSA-DT, the 5-year probability was 22.7%-39.4%. The difference was significant when BCR was defined as a PSA-DT ≤ 3 months and ≤ 6 months. Application of a PSA-DT ≤ 6 months yielded the highest c-index (0.660). These two parameters complemented each other; for patients meeting both PSA parameters, the probability of DM was 39.5%-44.5%; for those not meeting either parameter, the probability was 0.0%-3.1%.
Conclusion
A serum PSA level > 0.8 ng/mL was a reasonable threshold for the definition of BCR after SRT. In addition, a PSA-DT ≤ 6 months was significantly predictive of subsequent DM, and combined application of both parameters enhanced predictability.

Clinical Outcomes of Postoperative Radiotherapy Following Radical Prostatectomy in Patients with Localized Prostate Cancer: A Multicenter Retrospective Study (KROG 18-01) of a Korean Population: Sung Uk Lee, Kwan Ho Cho, Won Park, Won Kyung Cho, Jae-Sung Kim, Chan Woo Wee, Young Seok Kim, Jin Ho Kim, Taek-Keun Nam, Jaeho Cho, Song Mi Jeong, Youngkyong Kim, Su Jung Shim, Youngmin Choi, Jun-Sang Kim; Cancer Res Treat. 2020;52(1):167-180. Published online June 25, 2019; DOI: https://doi.org/10.4143/crt.2019.126

Abstract PDF Supplementary Material PubReader ePub

Purpose
The purpose of this study was to investigate the clinical outcomes of postoperative radiotherapy (PORT) patients who underwent radical prostatectomy for localized prostate cancer.
Materials and Methods
Localized prostate cancer patients who received PORT after radical prostatectomy between 2001 and 2012 were identified retrospectively in a multi-institutional database. In total, 1,117 patients in 19 institutions were included. Biochemical failure after PORT was defined as prostate-specific antigen (PSA) ≥ nadir+2 after PORT or initiation of androgen deprivation therapy (ADT) for increasing PSA regardless of its value.
Results
Ten-year biochemical failure-free survival, clinical failure-free survival, distant metastasisfree survival, overall survival (OS), and cause-specific survival were 60.5%, 76.2%, 84.4%, 91.1%, and 96.6%, respectively, at a median of 84 months after PORT. Pre-PORT PSA ≤ 0.5 ng/ml and Gleason’s score ≤ 7 predicted favorable clinical outcomes, with 10-year OS rates of 92.5% and 94.1%, respectively. The 10-year OS rate was 82.7% for patients with a PSA > 1.0 ng/mL and 86.0% for patients with a Gleason score of 8-10. The addition of longterm ADT (≥ 12 months) to PORT improved OS, particularly in those with a Gleason score of 8-10 or ≥ T3b.
Conclusion
Clinical outcomes of PORT in a Korean prostate cancer population were very similar to those in Western countries. Lower Gleason score and serum PSA level at the time of PORT were significantly associated with favorable outcomes. Addition of long-term ADT (≥ 12 months) to PORT should be considered, particularly in unfavorable risk patients with Gleason scores of 8-10 or ≥ T3b.

Treatment Outcome after Fractionated Conformal Radiotherapy for Hepatocellular Carcinoma in Patients with Child-Pugh Classification B in Korea (KROG 16-05): Sun Hyun Bae, Hee Chul Park, Won Sup Yoon, Sang Min Yoon, In-Hye Jung, Ik Jae Lee, Jun Won Kim, Jinsil Seong, Tae Hyun Kim, Taek-Keun Nam, Youngmin Choi, Sun Young Lee, Hong Seok Jang, Dong Soo Lee, Jin Hee Kim; Cancer Res Treat. 2019;51(4):1589-1599. Published online April 10, 2019; DOI: https://doi.org/10.4143/crt.2018.687

Abstract PDF Supplementary Material PubReader ePub

Purpose
There is limited data on radiotherapy (RT) for hepatocellular carcinoma (HCC) in patients with Child-Pugh classification B (CP-B). This study aimed to evaluate the treatment outcomes of fractionated conformal RT in HCC patients with CP-B.
Materials and Methods
We retrospectively reviewed the data of HCC patients with CP-B treated with RT between 2009 and 2014 at 13 institutions in Korea. HCC was diagnosed by the Korea guideline of 2009, and modern RT techniques were applied. Fraction size was ≤ 5 Gy and the biologically effective dose (BED) ≥ 40 Gy10 (α/β = 10 Gy). A total of 184 patients were included in this study.
Results
Initial CP score was seven in 62.0% of patients, eight in 31.0%, and nine in 7.0%. Portal vein tumor thrombosis was present in 66.3% of patients. The BED ranged from 40.4 to 89.6 Gy10 (median, 56.0 Gy10). After RT completion, 48.4% of patients underwent additional treatment. The median overall survival (OS) was 9.4 months. The local progression-free survival and OS rates at 1 year were 58.9% and 39.8%, respectively. In the multivariate analysis, non-classic radiation-induced liver disease (RILD) (p < 0.001) and additional treatment (p < 0.001) were the most significant prognostic factors of OS. Among 132 evaluable patients without progressive disease, 19.7% experienced non-classic RILD. Normal liver volume was the most predictive dosimetric parameter of non-classic RILD.
Conclusion
Fractionated conformal RT showed favorable OS with a moderate risk non-classic RILD. The individual radiotherapy for CP-B could be cautiously applied weighing the survival benefits and the RILD risks.

The Impact of Surgical Timing on Pathologic Tumor Response after Short Course and Long Course Preoperative Chemoradiation for Locally Advanced Rectal Adenocarcinoma: Sea-Won Lee, Jong Hoon Lee, In Kyu Lee, Seong Taek Oh, Dae Yong Kim, Tae Hyun Kim, Jae Hwan Oh, Ji Yeon Baek, Hee Jin Chang, Hee Chul Park, Hee Cheol Kim, Eui Kyu Chie, Taek-Keun Nam, Hong Seok Jang; Cancer Res Treat. 2018;50(3):1039-1050. Published online November 21, 2017; DOI: https://doi.org/10.4143/crt.2017.252

Abstract PDF PubReader ePub

Purpose
A pooled analysis of multi-institutional trials was performed to analyze the effect of surgical timing on tumor response by comparing short course concurrent chemoradiotherapy (CCRT) with long course CCRT followed by delayed surgery in locally advanced rectal cancer.
Materials and Methods
Three hundred patients with cT3-4N0-2 rectal adenocarcinoma were included. Long course patients from KROG 14-12 (n=150) were matched 1:1 to 150 short course patients from KROG 10-01 (NCT01129700) and KROG 11-02 (NCT01431599) according to stage, age, and other risk factors. The primary endpoint was to determine the interval between surgery and the last day of neoadjuvant CCRT which yields the best tumor response after the short course and long course CCRT. Downstaging was defined as ypT0-2N0M0 and pathologic complete response (ypCR) was defined as ypT0N0M0, respectively.
Results
Both the long and short course groups achieved lowest downstaging rates at < 6 weeks (long 20% vs. short 8%) and highest downstaging rates at 6-7 weeks (long 44% vs. short 40%). The ypCR rates were lowest at < 6 weeks (both long and short 0%) and highest at 6-7 weeks (long 21% vs. short 11%) in both the short and long course arms. The downstaging and ypCR rates of long course group gradually declined after the peak at 6-7 weeks and those of the short course group trend to constantly increase afterwards.
Conclusion
It is optimal to perform surgery at least 6 weeks after both the short course and long course CCRT to obtain maximal tumor regression in locally advanced rectal adenocarcinoma.

Published online June 13, 2016; DOI: https://doi.org/10.4143/crt.2016.097

Abstract PDF PubReader ePub

Purpose
The aim of this study was to examine patterns of radiotherapy (RT) in Korean patients with hepatocellular carcinoma (HCC) according to the evolving guideline for HCC established by the Korean Liver Cancer Study Group-National Cancer Center (KLCSG-NCC).
Materials and Methods
We reviewed 765 patients with HCC who were treated with RT between January 2011 and December 2012 in 12 institutions.
Results
The median follow-up period was 13.3 months (range, 0.2 to 51.7 months). Compared with previous data between 2004 and 2005, the use of RT as a first treatment has increased (9.0% vs. 40.8%). Increased application of intensity-modulated RT resulted in an increase in radiation dose (fractional dose, 1.8 Gy vs. 2.5 Gy; biologically effective dose, 53.1 Gy₁₀ vs. 56.3 Gy₁₀). Median overall survival was 16.2 months, which is longer than that reported in previous data (12 months). In subgroup analysis, treatments were significantly different according to stage (p < 0.001). Stereotactic body RT was used in patients with early HCC, and most patients with advanced stage were treated with three-dimensional conformal RT.
Conclusion
Based on the evolving KLCSG-NCC practice guideline for HCC, clinical practice patterns of RT have changed. Although RT is still used mainly in advanced HCC, the number of patients with good performance status who were treated with RT as a first treatment has increased. This change in practice patterns could result in improvement in overall survival.

Abstract PDF PubReader ePub

Purpose
This prospective study was designed to verify the technical feasibility of partial breast irradiation in breast cancer patients with small breasts, which are commonly encountered in Korean women. Materials and Methods A total of 40 Gy, administered in 10 fractions on consecutive days (one fraction per day), was prescribed to the isocenters of the fields using three-dimensional conformal radiotherapy (3-DCRT). For all patients, treatment planning and dose parameters strictly adhered to the constraints set forth in the Radiation Therapy Oncology Group (RTOG) 0319 protocol. This study was designed such that if fewer than five of the first 42 evaluable patients received unacceptable scores, the treatment would be considered reproducible. Results Ten treatment plans (23.8%) were determined to have major variations. There was no major variation in planning target volume (PTV) coverage. The ipsilateral and contralateral breast dose limitations were not met in four (9.5%) and four cases (9.5%), respectively. Major variations in ipsilateral and contralateral lung dose limitations were observed in two cases (4.8%). Major variations in the heart and thyroid dose limitations were observed in one (2.4%) and one case (2.4%), respectively. In multivariate analysis, a ratio of PTV to ipsilateral breast volume (PTV/IB) > 0.16 was the only significant factor that statistically affected major variations. Conclusion We concluded that partial breast irradiation using 3-DCRT could not be reproduced in Korean breast cancer patients, particularly small-volumed breast surrogated as PTV/IB > 0.16. The dominant cause was the major variation in surrounding normal breast tissues.

Purpose

To evaluate the treatment outcomes of local excision following preoperative chemoradiotherapy in patients with locally advanced rectal cancer who have not undergone radical surgery for any reason.

Materials and Methods

The data of 27 patients with locally advanced rectal cancer who underwent preoperative chemoradiotherapy followed by local excision were analyzed retrospectively. The primary endpoint was the 5-year relapse-free survival rate, and the secondary endpoint was the pattern of recurrence.

Results

The median follow-up time was 81.8 months (range, 28.6 to 138.5 months). The 5-year local relapse-free survival (LRFS), distant metastasis-free survival (DMFS), relapse-free survival (RFS), and overall survival (OS) were 88.9%, 81.1%, 77.8%, and 85.0%, respectively. Six (22%) patients developed treatment failure; one (4%) patient had local recurrence only, three (11%) patients had distant recurrence only, and two (7%) patients had both. The 5-year LRFS, DMFS, RFS, and OS for patients with ypT0-1 compared with ypT2-3 were 94.1% vs. 77.8% (p=0.244), 94.1% vs. 55.6% (p=0.016), 88.2% vs. 55.6% (p=0.051), and 94.1% vs. 66.7% (p=0.073), respectively.

Conclusion

Local excision following preoperative chemoradiotherapy may be an alternative treatment for highly selected patients with locally advanced rectal cancer who have achieved ypT0-1 after preoperative chemoradiotherapy.

Abstract PDF PubReader ePub

PURPOSE
To assess radiotherapy for patients with early stage gastric mucosa-associated lymphoid tissue (MALT) lymphoma with respect to survival, treatment response, and complications.
MATERIALS AND METHODS
Enrolled into this study were 48 patients diagnosed with gastric MALT lymphoma from January 2000 to September 2012. Forty-one patients had low grade and seven had mixed component with high grade. Helicobacter pylori eradication was performed in 33 patients. Thirty-four patients received radiotherapy alone. Ten patients received chemotherapy before radiotherapy, and three patients underwent surgery followed by chemotherapy and radiotherapy. One patient received surgery followed by radiotherapy. All patients received radiotherapy of median dose of 30.6 Gy.
RESULTS
The duration of follow-up ranged from 6 to 158 months (median, 48 months). Five-year overall survival and cause-specific survival rates were 90.3% and 100%. All patients treated with radiotherapy alone achieved pathologic complete remission (pCR) in 31 of the low-grade and in three of the mixed-grade patients. All patients treated with chemotherapy and/or surgery prior to radiotherapy achieved pCR except one patient who received chemotherapy before radiotherapy. During the follow-up period, three patients developed diffuse large B-cell lymphoma in the stomach, and one developed gastric adenocarcinoma after radiotherapy. No grade 3 or higher acute or late complications developed. One patient, who initially exhibited gastroptosis, developed mild atrophy of left kidney.
CONCLUSION
These findings indicate that a modest dose of radiotherapy alone can achieve a high cure rate for low-grade and even mixed-grade gastric MALT lymphoma without serious toxicity. Patients should be carefully observed after radiotherapy to screen for secondary malignancies.

Abstract PDF PubReader ePub

PURPOSE
Locally advanced esophageal cancers are generally treated with neoadjuvant chemoradiotherapy, followed by surgery in operable candidates. However, even if the patients were diagnosed as operable disease, surgery could not be performed on patients with poor condition or other comorbidity. In this case, definitive chemoradiotherapy (dCRT) is the other option for localized esophageal cancer. Therefore, the purpose of this study was to evaluate the efficacy and clinical prognostic factors for dCRT in locally advanced esophageal cancer.
MATERIALS AND METHODS
We conducted a review of patients who received dCRT for locally advanced squamous esophageal cancer from 2004 to 2010, focusing on stages III and IVa. All patients received at least two cycles of platinum-based chemotherapy during radiation, and all tumor burdens were included in the radiation field. The treatment results were analyzed for patterns of failure and prognostic factors associated with survival.
RESULTS
In total, 63 patients were enrolled in this study. The overall response rate was 84.1%. Relief from dysphagia after dCRT was achieved in 48 patients. The most frequent failure was local recurrence. The median overall survival (OS) was 23.0 months, and the 2-year survival rate was 45.4%. Similar results were observed for elderly study patients. Significant prognostic factors for OS were duration of smoking, high grade of dysphagia (score of 3 or 4), and shorter duration of progression-free and dysphagia-free survival. Maintenance chemotherapy after dCRT did not influence OS. However, "good risk" patients receiving maintenance chemotherapy showed better OS than those who did not receive maintenance chemotherapy (30.4 months vs. 12.0 months, p=0.002).
CONCLUSION
dCRT has a major role in improving survival and palliation of dysphagia in inoperable advanced esophageal cancer, even in elderly patients. Maintenance chemotherapy after dCRT may be effective in prolonging survival in "good risk" patients.

Abstract PDF PubReader ePub

Locally advanced non-small cell lung cancer (NSCLC) is a heterogeneous disease, and we have embarked on an era where patients will benefit from individualized therapeutic strategies based on identifiable molecular characteristics of the tumor. The landmark studies demonstrating the importance of molecular characterization of tumors for NSCLC patients, the promising molecular pathways, and the potential molecular targets/agents for treatment of this disease will be reviewed. Understanding these issues will aid in the development of rationally designed clinical trials, so as to determine best means of appropriately incorporating these molecular strategies, to the current standard of radiation and chemotherapy regimens, for the treatment of locally advanced NSCLC.

Results of Curative Radiation Therapy with or without Chemotherapy for Stage III Unresectable Non-Small Cell Lung Cancer: Sung-Ja Ahn, Young-Chul Kim, Kyu-Sik Kim, Kyung-Ok Park, Woong-Ki Chung, Taek-Keun Nam, Byung-Sik Nah, Ju-Young Song, Mi-Sun Yoon; Cancer Res Treat. 2005;37(5):268-272. Published online October 31, 2005; DOI: https://doi.org/10.4143/crt.2005.37.5.268

Abstract PDF PubReader ePub

Purpose

We retrospectively analyzed the patients who received curative radiotherapy for unresectable stage III NSCLC to investigate the impact of chemotherapy.

Materials and Methods

From 1998 to 2001, the records of 224 patients who completed curative radiotherapy for NSCLC were reviewed. There were 210 males and 14 females, and their median age was 64 years (range 38~83). 54 patients had stage IIIA disease and 170 patients had stage IIIB disease. Conventional radiotherapy was given and the radiation dose ranged from 50~70 Gy with a median of 60 Gy, and chemotherapy was combined for 116 patients (52%).

Results

The median survival, the 2-year, and 5-year actuarial survival rates of all 224 patients were 15 months, 30%, and 7%, respectively. The median survival of the patients with stage IIIA and IIIB disease were 21 months and 13 months, respectively (p=0.14). The median survival of patients who received chemoradiation was 18 months compared to 14 months for the patients who received RT alone (p=0.02). Among the chemoradiation group of patients, the median survival time of the patients who received 1 to 3 cycles of chemotherapy was 16 months and that for the patients who received more than 3 cycles was 22 months (p=0.07). We evaluated the effects of the timing of chemoradiation in 57 patients who received more than 3 cycles of chemotherapy. The median survival of the patients with the concurrent sequence was 25 months and that for the patients with the sequential chemotherapy was 19 months (p=0.81).

Conclusions

For advanced stage III non-small cell lung cancer patients who completed the curative radiotherapy, the addition of chemotherapy improved the survival compared to the patients who received radiotherapy alone.

Abstract PDF PubReader ePub

Purpose

To assess tumor regression, as determined by pelvic magnetic resonance imaging (MRI), and evaluate the efficacies and toxicities of the interim brachytherapy (BT) modification method, according to tumor regression during multi-fractionated high-dose-rate (HDR) BT for uterine cervical cancer.

Materials and Methods

Consecutive MRI studies were performed pre-radiotherapy (RT), pre-BT and during interfraction of BT (inter-BT) in 69 patients with cervical cancer. External beam radiotherapy (EBRT) was performed, using a 10 MV X-ray, in daily fraction of 1.8 Gy with 4-fields, 5 d/wk. Radiation was delivered up to 50.4 Gy, with midline shielding at around 30.6 Gy. Of all 69 patients, 50 received modified interim BT after checking the inter-BT MRI. The BT was delivered in two sessions; the first was composed of several 5 Gy fractions to point A, twice weekly, using three channel applicators. According to the three measured orthogonal diameters of the regressed tumor, based on inter-BT MR images, the initial BT plan was modified, with the second session consisting of a few fractions of less than 5 Gy to point A, using a cervical cylinder applicator.

Results

The numbers of patients in FIGO stages Ib, IIa, IIb and IIIb+IVa were 19 (27.5%), 18 (26.1%), 27 (39.2%) and 5 (7.2%), respectively. Our treatment characteristics were comparable to those from the literatures with respect to the biologically effective dose (BED) to point A, rectum and bladder as reference points. In the regression analysis a significant correlation was observed between tumor regression and the cumulative dose to point A on the follow-up MRI. Nearly 80% regression of the initial tumor volume occurred after 30.6 Gy of EBRT, and this increased to 90% after an additional 25 Gy in 5 fractions of BT, which corresponds to 73.6 Gy of cumulative BED₁₀ to point A. The median total fraction number, and those at the first and second sessions of BT were 8 (5~10), 5 (3~7) and 3 (1~5), respectively. The median follow-up time was 53 months (range, 9~66 months). The 4-year disease-free survival rate of all patients was 86.8%. Six (8.7%) patients developed pelvic failures, but major late complications developed in only two (2.9%).

Conclusion

Our study shows that effective tumor control, equivalent survival and low rates of major complications can be achieved by modifying the fraction size during BT according to tumor regression, as determined by consecutive MR images. We recommend checking the follow-up MRI at a cumulative BED₁₀ of around 65 Gy to point A, with the initial BT modified at a final booster BT session.
