Implication of Pre- and Post-radiotherapy ctDNA Dynamics in Patients with Residual Triple-Negative Breast Cancer at Surgery after Neoadjuvant Chemotherapy: Findings from a Prospective Observational Study: Tae Hoon Lee, Haeyoung Kim, Yeon Jeong Kim, Woong-Yang Park, Won Park, Won Kyung Cho, Nalee Kim; Cancer Res Treat. 2024;56(2):531-537. Published online November 10, 2023; DOI: https://doi.org/10.4143/crt.2023.996

Purpose
This study aims to determine the association between pre- and postoperative radiotherapy (PORT) circulating tumor DNA (ctDNA) dynamics and oncological outcomes in patients with residual triple-negative breast cancer who underwent surgery after neoadjuvant chemotherapy (NAC).
Materials and Methods
Between March 2019 and July 2020, 11 nonmetastatic patients with residual disease who underwent surgery after NAC were prospectively enrolled. In each patient, tumor specimens obtained during surgery and blood samples collected at three time points during PORT (T0: pre-PORT, T1: 3 weeks after PORT, T2: 1 month after PORT) were sequenced, targeting 38 cancer-related genes. Disease-free survival (DFS) was evaluated and the association between DFS and ctDNA dynamics was analyzed.
Results
At T0, ctDNA was detected in three (27.2%) patients. The ctDNA dynamics were as follows: two showed a decreasing ctDNA variant allele frequency (VAF) and reached zero VAF at T2, while one patient exhibited an increasing VAF during PORT and maintained an elevated VAF at T2. After a median follow-up of 48 months, two patients experienced distant metastasis without any locoregional failures. All failures occurred in patients with ctDNA positivity at T0 and a decreased VAF after PORT. The 4-year DFS rates according to the T0 ctDNA status were 67% (positive ctDNA) and 100% (negative ctDNA) (p=0.032).
Conclusion
More than a quarter of the patients with residual disease after post-NAC surgery exhibited pre-PORT ctDNA positivity, and ctDNA positivity was associated with poor DFS. For patients with pre-PORT ctDNA positivity, the administration of a more effective systemic treatment should be considered.

Epidemiology of Second Non-breast Primary Cancers among Survivors of Breast Cancer: A Korean Population–Based Study by the SMARTSHIP Group: Haeyoung Kim, Su SSan Kim, Ji Sung Lee, Jae Sun Yoon, Hyun Jo Youn, Hyukjai Shin, Jeong Eon Lee, Se Kyung Lee, Il Yong Chung, So-Youn Jung, Young Jin Choi, Jihyoung Cho, Sang Uk Woo, Korean Breast Cancer Society; Cancer Res Treat. 2023;55(2):580-591. Published online December 27, 2022; DOI: https://doi.org/10.4143/crt.2022.410

Abstract PDF Supplementary Material PubReader ePub

Purpose
This study aimed to evaluate the incidence and prognosis of second non-breast primary cancer (SNBPC) among Korean survivors of breast cancer.
Materials and Methods
Data from the Korean National Health Insurance Service were searched to identify women who received curative surgery for initial breast cancer (IBC) between 2003 and 2008 (n=64,340). Among them, patients with the following characteristics were excluded: other cancer diagnosis before IBC (n=10,866), radiotherapy before IBC (n=349), absence of data on sex or age (n=371), or male (n=248). Accordingly, data of 52,506 women until December 2017 were analyzed. SNBPC was defined as a newly diagnosed SNBPC that occurred 5 years or more after IBC diagnosis.
Results
The median follow-up time of all patients was 12.13 years. SNBPC was developed in 3,084 (5.87%) women after a median of 7.61 years following IBC diagnosis. The 10-year incidence of SNBPC was 5.78% (95% confidence interval [CI], 5.56 to 6.00). Higher SNBPC incidence was found in survivors with the following factors: old age at IBC diagnosis, low household income, and receiving combined chemotherapy with endocrine therapy, whereas receiving radiotherapy was related to a lower incidence of SNBPC (hazard ratio, 0.89; p < 0.01). Among the patients with SNBPC, the 5-year survival rate was 62.28% (95% CI, 65.53 to 69.02).
Conclusion
Approximately 5% of breast cancer survivors developed SNBPC within 10 years after IBC diagnosis. The risk of SNBPC was associated with patient’s age at IBC diagnosis, income level, and a receipt of systemic treatments.

Purpose
To evaluate the role of postmastectomy radiation therapy (PMRT) in patients with node-negative breast cancer of 5cm or larger tumors undergoing mastectomy
Materials and Methods
Medical records of 274 patients from 18 institutions treated with mastectomy between January 2000 and December 2016 were retrospectively reviewed. Among these, 202 patients underwent PMRT, while 72 did not. Two hundred and forty-one patients (88.0%) received systemic chemotherapy, and 172 (62.8%) received hormonal therapy. Patients receiving PMRT were younger, more likely to have progesterone receptor-positive tumors, and received adjuvant chemotherapy more frequently compared with those without PMRT (p <0.001, 0.018, and <0.001, respectively). Other characteristics were not significantly different between the two groups.
Results
With a median follow-up of 95 months (range, 1-249), there were 9 locoregional recurrences, and 20 distant metastases. The 8-year locoregional recurrence-free survival rates were 98.0% with PMRT and 91.3% without PMRT (p=0.133), and the 8-year disease-free survival (DFS) rates were 91.8% with PMRT and 73.9% without PMRT (p=0.008). On multivariate analysis incorporating age, histologic grade, lymphovascular invasion, hormonal therapy, chemotherapy, and PMRT, the absence of lymphovascular invasion and the receipt of PMRT were associated with improved DFS (p=0.025 and 0.009, respectively).
Conclusion
Locoregional recurrence rate was very low in node-negative breast cancer of 5cm or larger tumors treated with mastectomy regardless of the receipt of PMRT. However, PMRT was significantly associated with improved DFS. Further investigation is needed to confirm these findings.

Prognostic Impact of Elective Supraclavicular Nodal Irradiation for Patients with N1 Breast Cancer after Lumpectomy and Anthracycline Plus Taxane-Based Chemotherapy (KROG 1418): A Multicenter Case-Controlled Study: Haeyoung Kim, Won Park, Jeong Il Yu, Doo Ho Choi, Seung Jae Huh, Yeon-Joo Kim, Eun Sook Lee, Keun Seok Lee, Han-Sung Kang, In Hae Park, Kyung Hwan Shin, Chan Woo Wee, Kyubo Kim, Kyung Ran Park, Yong Bae Kim, Sung Ja Ahn, Jong Hoon Lee, Jin Hee Kim, Mison Chun, Hyung-Sik Lee, Jung Soo Kim, Jihye Cha; Cancer Res Treat. 2017;49(4):970-980. Published online January 4, 2017; DOI: https://doi.org/10.4143/crt.2016.382

Abstract PDF Supplementary Material PubReader ePub

Purpose
This study was conducted to evaluate the impact of supraclavicular lymph node radiotherapy (SCNRT) on N1 breast cancer patients receiving post-lumpectomy whole-breast irradiation (WBI) and anthracycline plus taxane-based (AT) chemotherapy.
Materials and Methods
We performed a case-control analysis to compare the outcomes of WBI and WBI plus SCNRT (WBI+SCNRT). Among 1,147 patients with N1 breast cancer who received post-lumpectomy radiotherapy and AT-based chemotherapy in 12 hospitals, 542 were selected after propensity score matching. Patterns of failure, disease-free survival (DFS), distant metastasis-free survival (DMFS), and treatment-related toxicity were compared between groups.
Results
A total of 41 patients (7.6%) were found to have recurrence. Supraclavicular lymph node (SCN) failure was detected in three patients, two in WBI and one in WBI+SCNRT. All SCN failures were found simultaneously with distant metastasis. There was no significant difference in patterns of failure or survival between groups. The 5-year DFS and DMFS for patients with WBI and WBI+SCNRT were 94.4% versus 92.6% (p=0.50) and 95.1% versus 94.5% (p=0.99), respectively. The rates of lymphedema and radiation pneumonitis were significantly higher in the WBI+SCNRT than in the WBI.
Conclusion
We did not find a benefit of SCNRT for N1 breast cancer patients receiving AT-based chemotherapy.

Purpose
The purpose of this study was to evaluate the impact of postmastectomy radiotherapy (PMRT) on loco-regional recurrence-free survival (LRRFS), disease-free survival (DFS), and overall survival (OS) in pT1-2N1 patients treated with taxane-based chemotherapy.
Materials and Methods
We retrospectively reviewed the medical data of pathological N1 patients who were treated with modified radical mastectomy and adjuvant taxane-based chemotherapy in 12 hospitals between January 2006 and December 2010.
Results
We identified 714 consecutive patients. The median follow-up duration was 69 months (range, 1 to 114 months) and the 5-year LRRFS, DFS, and OS rates were 97%, 94%, and 98%, respectively, in patients who received PMRT (PMRT [+]). The corresponding figures were 96%, 90%, and 96%, respectively, in patients who did not receive PMRT (PMRT [–]). PMRT had no significant impact on survival. Upon multivariable analysis, only the histological grade (HG) was statistically significant as a prognostic factor for LRRFS and DFS. In a subgroup analysis of HG 3 patients, PMRT (+) showed better DFS (p=0.081).
Conclusion
PMRT had no significant impact on LRRFS, DFS, or OS in pT1-2N1 patients treated with taxane-based chemotherapy. PMRT showed a marginal benefit for DFS in HG 3 patients. Randomized studies are needed to confirm the benefit of PMRT in high risk patients, such as those with HG 3.

Analysis of BRIP1 Variants among Korean Patients with BRCA1/2 Mutation-Negative High-Risk Breast Cancer: Haeyoung Kim, Dae-Yeon Cho, Doo Ho Choi, Gee Hue Jung, Inkyung Shin, Won Park, Seung Jae Huh, Seok Jin Nam, Jeong Eon Lee, Won Ho Gil, Seok Won Kim; Cancer Res Treat. 2016;48(3):955-961. Published online January 19, 2016; DOI: https://doi.org/10.4143/crt.2015.191

Abstract PDF PubReader ePub

Purpose
The aim of the current study is to assess the spectrum of genetic variation in the BRIP1 gene among Korean high-risk breast cancer patients who tested negative for the BRCA1/2 mutation.
Materials and Methods
Overall, 235 Korean patientswith BRCA1/2 mutation–negative high-risk breast cancerwere screened for BRIP1 mutations. The entire BRIP1 gene was analyzed using fluorescent-conformation sensitive gel electrophoresis. In silico analysis of BRIP1 variants was performed using PolyPhen-2 and SIFT.
Results
A total of 20 sequence alterations including 12 exonic and eight intronic variantswere found. Among the 12 exonic variants, 10 were missense and two were silent mutations. No protein-truncating mutation was found among the tested patients. Among the 10 missense variants, four (p.L263F, p.L340F, p.L474P, and p.R848H) were predicted to be pathogenic by both PolyPhen-2 and SIFT, and these variants were found in five patients. Of the four missense variants, p.L263F, p.L474P, and p.R848H localize to regions between the helicase motifs, while p.L340F resides in an iron-sulfur domain of BRIP1.
Conclusion
No protein-truncating mutation in BRIP1 was found among the tested patients. The contribution of BRIP1 variants is thought to be minor in Korean non-BRCA1/2 high-risk breast cancer.

Impact on Loco-regional Control of Radiochemotherapeutic Sequence and Time to Initiation of Adjuvant Treatment in Stage II/III Rectal Cancer Patients Treated with Postoperative Concurrent Radiochemotherapy: Haeyoung Kim, Eui Kyu Chie, Yong Chan Ahn, Kyubo Kim, Won Park, Won Sup Yoon, Seung Jae Huh, Sung W. Ha; Cancer Res Treat. 2014;46(2):148-157. Published online April 15, 2014; DOI: https://doi.org/10.4143/crt.2014.46.2.148

Abstract PDF PubReader ePub

Purpose

This study was designed to evaluate the impact of radiochemotherapeutic sequence and time to initiation of adjuvant treatment on loco-regional control for resected stage II and III rectal cancer.

Materials and Methods

Treatment outcomes for rectal cancer patients from two hospitals with different sequencing strategies regarding adjuvant concurrent radiochemotherapy (CRCT) were compared retrospectively. Pelvic radiotherapy was administered concurrently on the first (early CRCT, n=180) or the third cycle of chemotherapy (late CRCT, n=180). During radiotherapy, two cycles of fluorouracil were provided to patients in both groups. In the early CRCT group, median six cycles of fluorouracil and leucovorin were prescribed during the post-CRCT period. In the late CRCT group, two cycles of fluorouracil were administered in the pre- and post-CRCT periods.

Results

No significant differences in the 5-year loco-regional recurrence-free survival (LRRFS) (92.5% vs. 95.6%, p=0.43) or overall survival and disease-free survival were observed between groups. Patients who began receiving adjuvant treatment later than five weeks after surgery had lower LRRFS than patients who received adjuvant treatment within five weeks following surgery (79% vs. 91%, p<0.01). The risk of loco-regional recurrence increased as the time to initiation of adjuvant treatment was delayed.

Conclusion

In the current study, treatment outcomes were not significantly influenced by the sequence of adjuvant treatment but by the delay of adjuvant treatment for more than five weeks. Timely administration of adjuvant treatment is deemed important in achieving loco-regional tumor control for stage II/III rectal cancer patients.
