Clinical Characteristics of and Treatment Pattern for EGFR-Amplified Colorectal Cancer: Seong-Eun Kim, Hyehyun Jeong, Sun Young Kim, Jeong Eun Kim, Yong Sang Hong, Deokhoon Kim, Jihun Kim, Ji Sung Lee, Tae-Won Kim; Received June 17, 2024 Accepted January 7, 2025 Published online January 10, 2025; DOI: https://doi.org/10.4143/crt.2024.569 [Accepted]

Abstract PDF: Purpose
To compare clinicopathologic features and clinical outcomes of metastatic colorectal cancer (mCRC) based on EGFR amplification status.
Materials and Methods
Patients with mCRC who underwent next-generation sequencing using a targeted 244-gene panel from 2016 to 2021 were identified and screened for EGFR copy numbers. Cases with at least 5 copies were reviewed for tumor purity adjustment, and those with an adjusted copy number of ≥6 were defined as EGFR-amplified (EGFR amp+). Their clinical characteristics were compared with those without EGFR amplification (EGFR amp-).
Results
Among 2,421 patients, 35 (1.4%) were EGFR amp+. Clinical characteristics did not significantly differ according to EGFR amplification status, but EGFR amp+ cases had fewer instances of peritoneal seeding (8.6% vs. 21.8%). Overall survival (OS) tended to be better in EGFR amp+ patients compared with EGFR amp- patients (median OS 76 vs. 37 months, p=0.15). Among 572 patients who received anti-EGFR antibody-based chemotherapy (anti-EGFR CTx) during disease course, mOS tended to be better in 16 EGFR amp+ patients (79 months) compared with 556 EGFR amp- patients (39 months, p=0.048). Seven out of 35 EGFR amp+ patients were treated with front-line anti-EGFR CTx, and their progression-free survival did not differ from that of EGFR amp- patients treated with front-line anti-EGFR CTx (20 vs. 14 months, p=0.344).
Conclusion
This study may suggest a favorable predictive impact of EGFR amplification in patients treated with anti-EGFR CTx. However, the benefit of front-line anti-EGFR antibody treatment in this group was not notable.

Factors Affecting Life-Sustaining Treatment Decisions and Changes in Clinical Practice after Enforcement of the Life-Sustaining Treatment (LST) Decision Act: A Tertiary Hospital Experience in Korea: Yoon Jung Jang, Yun Jung Yang, Hoi Jung Koo, Hye Won Yoon, Seongbeom Uhm, Sun Young Kim, Jeong Eun Kim, Jin Won Huh, Tae Won Kim, Seyoung Seo; Cancer Res Treat. 2025;57(1):280-288. Published online July 1, 2024; DOI: https://doi.org/10.4143/crt.2024.360

Abstract PDF Supplementary Material PubReader ePub: Purpose
In Korea, the Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment (LST) was implemented on February 4, 2018. We aimed to investigate relevant factors and clinical changes associated with LST decisions after law enforcement.
Materials and Methods
This single-center retrospective study included patients who completed LST documents using legal forms at Asan Medical Center from February 5, 2018, to June 30, 2020.
Results
5,896 patients completed LST documents, of which 2,704 (45.8%) signed the documents in person, while family members of 3,192 (54%) wrote the documents on behalf of the patients. Comparing first year and following year of implementation of the act, the self-documentation rate increased (43.9% to 47.2%, p=0.014). Moreover, the number of LST decisions made during or after intensive care unit admission decreased (37.8% vs. 35.2%, p=0.045), and the completion rate of LST documents during chemotherapy increased (6.6% vs. 8.9%, p=0.001). In multivariate analysis, age < 65 (odds ratio [OR], 1.724; 95% confidence interval [CI], 1.538 to 1.933; p < 0.001), unmarried status (OR, 1.309; 95% CI, 1.097 to 1.561; p=0.003), palliative care consultation (OR, 1.538; 95% CI, 1.340 to 1.765; p < 0.001), malignancy (OR, 1.864; 95% CI, 1.628 to 2.133; p < 0.001), and changes in timing on the first year versus following year (OR, 1.124; 95% CI, 1.003 to 1.260; p=0.045) were related to a higher self-documentation rate.
Conclusion
Age < 65 years, unmarried status, malignancy, and referral to a palliative care team were associated with patients making LST decisions themselves. Furthermore, the subject and timing of LST decisions have changed with the LST act.

Phase 1/2a Study of Rivoceranib, a Selective VEGFR-2 Angiogenesis Inhibitor, in Patients with Advanced Solid Tumors: Yoon-Koo Kang, Min-Hee Ryu, Yong Sang Hong, Chang-Min Choi, Tae Won Kim, Baek-Yeol Ryoo, Jeong Eun Kim, John R. Weis, Rachel Kingsford, Cheol Hee Park, Seong Jang, Arlo McGinn, Theresa L. Werner, Sunil Sharma; Cancer Res Treat. 2024;56(3):743-750. Published online January 18, 2024; DOI: https://doi.org/10.4143/crt.2023.980

Abstract PDF Supplementary Material PubReader ePub: Purpose
This study aimed to report the results from an early-phase study of rivoceranib, an oral tyrosine kinase inhibitor highly selective for vascular endothelial growth factor receptor 2, in patients with advanced solid tumors.
Materials and Methods
In this open-label, single-arm, dose-escalating, multicenter three-part phase 1/2a trial, patients had advanced solid tumors refractory to conventional therapy. Part 1 evaluated the safety and pharmacokinetics of five ascending once-daily doses of rivoceranib from 81 mg to 685 mg. Part 2 evaluated the safety and antitumor activity of once-daily rivoceranib 685 mg. Part 3 was conducted later, due to lack of maximum tolerated dose determination in part 1, to evaluate the safety and preliminary efficacy of once-daily rivoceranib 805 mg in patients with unresectable or advanced gastric cancer.
Results
A total of 61 patients were enrolled in parts 1 (n=25), 2 (n=30), and 3 (n=6). In parts 1 and 2, patients were white (45.5%) or Asian (54.5%), and 65.6% were male. The most common grade ≥ 3 adverse events were hypertension (32.7%), hyponatremia (10.9%), and hypophosphatemia (10.9%). The objective response rate (ORR) was 15.2%. In part 3, dose-limiting toxicities occurred in two out of six patients: grade 3 febrile neutropenia decreased appetite, and fatigue. The ORR was 33%.
Conclusion
The recommended phase 2 dose of rivoceranib was determined to be 685 mg once daily, which showed adequate efficacy with a manageable safety profile (NCT01497704 and NCT02711969).

Impact of Patient Sex on Adverse Events and Unscheduled Utilization of Medical Services in Cancer Patients Undergoing Adjuvant Chemotherapy: A Multicenter Retrospective Cohort Study: Songji Choi, Seyoung Seo, Ju Hyun Lee, Koung Jin Suh, Ji-Won Kim, Jin Won Kim, Se Hyun Kim, Yu Jung Kim, Keun-Wook Lee, Jwa Hoon Kim, Tae Won Kim, Yong Sang Hong, Sun Young Kim, Jeong Eun Kim, Sang-We Kim, Dae Ho Lee, Jae Cheol Lee, Chang-Min Choi, Shinkyo Yoon, Su-Jin Koh, Young Joo Min, Yongchel Ahn, Hwa Jung Kim, Jin Ho Baek, Sook Ryun Park, Jee Hyun Kim; Cancer Res Treat. 2024;56(2):404-413. Published online November 7, 2023; DOI: https://doi.org/10.4143/crt.2023.784

Abstract PDF Supplementary Material PubReader ePub

Purpose
The female sex is reported to have a higher risk of adverse events (AEs) from cytotoxic chemotherapy. Few studies examined the sex differences in AEs and their impact on the use of medical services during adjuvant chemotherapy. This sub-study aimed to compare the incidence of any grade and grade ≥ 3 AEs, healthcare utilization, chemotherapy completion rate, and dose intensity according to sex.
Materials and Methods
This is a sub-study of a multicenter cohort conducted in Korea that evaluated the impact of healthcare reimbursement on AE evaluation in patients who received adjuvant chemotherapy between September 2013 and December 2016 at four hospitals in Korea.
Results
A total of 1,170 patients with colorectal, gastric, or non–small cell lung cancer were included in the study. Female patients were younger, had fewer comorbidities, and experienced less postoperative weight loss of > 10%. Females had significantly higher rates of any grade AEs including nausea, abdominal pain, stomatitis, vomiting, and neutropenia, and experienced more grade ≥ 3 neutropenia, nausea, and vomiting. The dose intensity of chemotherapy was significantly lower in females, and they also experienced more frequent dose reduction after the first cycle. Moreover, female patients receiving platinum-containing regimens had significantly higher rates of unscheduled outpatient visits.
Conclusion
Our study found that females experienced a higher incidence of multiple any-grade AEs and severe neutropenia, nausea, and vomiting, across various cancer types, leading to more frequent dose reductions. Physicians should be aware of sex differences in AEs for chemotherapy decisions.

Whole-Genome and Transcriptome Sequencing Identified NOTCH2 and HES1 as Potential Markers of Response to Imatinib in Desmoid Tumor (Aggressive Fibromatosis): A Phase II Trial Study: Joonha Kwon, Jun Hyeong Lee, Young Han Lee, Jeeyun Lee, Jin-Hee Ahn, Se Hyun Kim, Seung Hyun Kim, Tae Il Kim, Kum-Hee Yun, Young Suk Park, Jeong Eun Kim, Kyu Sang Lee, Jung Kyoon Choi, Hyo Song Kim; Cancer Res Treat. 2022;54(4):1240-1255. Published online January 17, 2022; DOI: https://doi.org/10.4143/crt.2021.1194

Abstract PDF Supplementary Material PubReader ePub

Purpose
Desmoid tumor, also known as aggressive fibromatosis, is well-characterized by abnormal Wnt/β-catenin signaling. Various therapeutic options, including imatinib, are available to treat desmoid tumor. However, the molecular mechanism of why imatinib works remains unclear. Here, we describe potential roles of NOTCH2 and HES1 in clinical response to imatinib at genome and transcriptome levels.
Materials and Methods
We identified somatic mutations in coding and noncoding regions via whole-genome sequencing. To validate the genetic interaction with expression level in desmoid-tumor condition, we utilized large-scale whole-genome sequencing and transcriptome datasets from the Pan-Cancer Analysis of Whole Genomes project. RNA-sequencing was performed using prospective and retrospective cohort samples to evaluate the expressional relevance with clinical response.
Results
Among 20 patients, four (20%) had a partial response and 14 (66.7%) had stable disease, 11 of which continued for ≥ 1 year. With gene-wise functional analyses, we detected a significant correlation between recurrent NOTCH2 noncoding mutations and clinical response to imatinib. Based on Pan-Cancer Analysis of Whole Genomes data analyses, NOTCH2 mutations affect expression levels particularly in the presence of CTNNB1 missense mutations. By analyzing RNA-sequencing with additional desmoid tumor samples, we found that NOTCH2 expression was significantly correlated with HES1 expression. Interestingly, NOTCH2 had no statistical power to discriminate between responders and non-responders. Instead, HES1 was differentially expressed with statistical significance between responders and non-responders.
Conclusion
Imatinib was effective and well tolerated for advanced desmoid tumor treatment. Our results show that HES1, regulated by NOTCH2, as an indicator of sensitivity to imatinib, and an important therapeutic consideration for desmoid tumor.

Histopathologic and Molecular Biomarkers of PD-1/PD-L1 Inhibitor Treatment Response among Patients with Microsatellite Instability‒High Colon Cancer: Jaewon Hyung, Eun Jeong Cho, Jihun Kim, Jwa Hoon Kim, Jeong Eun Kim, Yong Sang Hong, Tae Won Kim, Chang Ohk Sung, Sun Young Kim; Cancer Res Treat. 2022;54(4):1175-1190. Published online January 12, 2022; DOI: https://doi.org/10.4143/crt.2021.1133

Abstract PDF Supplementary Material PubReader ePub

Purpose
Recent clinical trials have reported response rates < 50% among patients treated with programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors for microsatellite instability‒high (MSI-H) colorectal cancer (CRC), and factors predicting treatment response have not been fully identified. This study aimed to identify potential biomarkers of PD-1/PD-L1 inhibitor treatment response among patients with MSI-H CRC.
Materials and Methods
MSI-H CRC patients enrolled in three clinical trials of PD-1/PD-L1 blockade at Asan Medical Center (Seoul, Republic of Korea) were screened and classified into two groups according to treatment response. Their histopathologic features and expression of 730 immune-related genes from the NanoString platform were evaluated, and a machine learning–based classification model was built to predict treatment response among MSI-H CRCs patients.
Results
A total of 27 patients (15 responders, 12 non-responders) were included. A high degree of lymphocytic/neutrophilic infiltration and an expansile tumor border were associated with treatment response and prolonged progression-free survival (PFS), while mucinous/signet-ring cell carcinoma was associated with a lack of treatment response and short PFS. Gene expression profiles revealed that the interferon-γ response pathway was enriched in the responder group. Of the top eight differentially expressed immune-related genes, PRAME had the highest fold change in the responder group. Higher expression of PRAME was independently associated with better PFS along with histologic subtypes in the multivariate analysis. The classification model using these genes showed good performance for predicting treatment response.
Conclusion
We identified histologic and immune-related gene expression characteristics associated with treatment response in MSI-H CRC, which may contribute to optimal patient stratification.

Radiofrequency Ablation versus Stereotactic Body Radiation Therapy in the Treatment of Colorectal Cancer Liver Metastases: Jesang Yu, Dong Hwan Kim, Jungbok Lee, Yong Moon Shin, Jong Hoon Kim, Sang Min Yoon, Jinhong Jung, Jin Cheon Kim, Chang Sik Yu, Seok-Byung Lim, In Ja Park, Tae Won Kim, Yong Sang Hong, Sun Young Kim, Jeong Eun Kim, Jin-hong Park, So Yeon Kim; Cancer Res Treat. 2022;54(3):850-859. Published online October 13, 2021; DOI: https://doi.org/10.4143/crt.2021.674

Abstract PDF Supplementary Material PubReader ePub

Purpose
This study aimed to compare the treatment outcomes of radiofrequency ablation (RFA) and stereotactic body radiation therapy (SBRT) for colorectal cancer liver metastases (CRLM) and to determine the favorable treatment modality according to tumor characteristics.
Materials and Methods
We retrospectively analyzed the records of 222 colorectal cancer patients with 330 CRLM who underwent RFA (268 tumors in 178 patients) or SBRT (62 tumors in 44 patients) between 2007 and 2014. Kaplan–Meier method and Cox models were used by adjusting with inverse probability of treatment weighting (IPTW).
Results
The median follow-up duration was 30.5 months. The median tumor size was significantly smaller in the RFA group than in the SBRT group (1.5 cm vs 2.3 cm, p<0.001). In IPTW-adjusted analysis, difference in treatment modality was not associated with significant differences in 1-year and 3-year recurrence-free survival (35% vs 43%, 22% vs 23%; p=0.198), overall survival (96% vs 91%, 58% vs 56%; p=0.508), and freedom from local progression (FFLP; 90% vs 72%, 78% vs 60%; p=0.106). Significant interaction effect between the treatment modality and tumor size was observed for FFLP (p=0.001). In IPTW-adjusted subgroup analysis of patients with tumor size >2 cm, the SBRT group had a higher FFLP compared with the RFA group (HR, 0.153; p<0.001).
Conclusion
SBRT and RFA showed similar local control in the treatment of patients with CRLM. Tumor size was an independent prognostic factor for local control and SBRT may be preferred for larger tumors.

Functional Impairments in the Mental Health, Depression and Anxiety Related to the Viral Epidemic, and Disruption in Healthcare Service Utilization among Cancer Patients in the COVID-19 Pandemic Era: Kyumin Kim, Harin Kim, Joohee Lee, Inn-Kyu Cho, Myung Hee Ahn, Ki Young Son, Jeong Eun Kim, Hee Jeong Kim, Sang Min Yoon, So Hee Kim, Moon Jung Kwon, Hwa Jung Kim, Su-Jin Koh, Seyoung Seo, Seockhoon Chung; Cancer Res Treat. 2022;54(3):671-679. Published online September 17, 2021; DOI: https://doi.org/10.4143/crt.2021.585

Abstract PDF PubReader ePub

Purpose
Literature is scarce regarding cancer care utilization during the massive outbreak of coronavirus disease 2019 (COVID-19) in the Republic of Korea. We investigated functional impairments in mental health and their relationships with depression, anxiety regarding the viral epidemic, and disruptions in healthcare service utilization among cancer patients in the COVID-19 pandemic era.
Materials and Methods
We used an online survey with questions related to the disturbances faced by patients with cancer in utilizing healthcare services in the pandemic era. Current mental health status was assessed using the Work and Social Adjustment Scale (WSAS), Stress and Anxiety to Viral Epidemics-6 (SAVE-6) scale, Patient Health Questionnaire-9 (PHQ-9), Insomnia Severity Index (ISI), Brief Resilience Scale (BRS), Cancer-Related Dysfunctional Beliefs about Sleep Scale (C-DBS), and Fear of COVID-19 over Cancer (FCC).
Results
Among the 221 responders, 95 (43.0%) reported disruptions in healthcare service utilization during the COVID-19 pandemic. Logistic regression analysis revealed that functional impairment in the mental health of these patients was expected due to disruptions in healthcare service utilization, high levels of depression, anxiety regarding the viral epidemic, fear of COVID over cancer, and low resilience. Mediation analysis showed that patient resilience and cancer-related dysfunctional beliefs about sleep partially mediated the effects of viral anxiety on functional impairment.
Conclusion
In this pandemic era, patients with cancer experience depression, anxiety regarding the viral epidemic, and disruptions in healthcare service utilization, which may influence their functional impairments in mental health.

Sarcoma

Clinicopathologic Characteristics and Clinical Outcome of Localized Liposarcoma: A Single-Center Experience over 25 Years and Evaluation of PD-L1 Expression: Heejung Chae, Jeong Eun Kim, Wanlim Kim, Jong-Seok Lee, Si Yeol Song, Min Hee Lee, Hye Won Chung, Kyung-Ja Cho, Joon Seon Song, Jin-Hee Ahn; Cancer Res Treat. 2022;54(2):579-589. Published online July 6, 2021; DOI: https://doi.org/10.4143/crt.2021.496

Abstract PDF Supplementary Material PubReader ePub

Purpose
For liposarcoma (LPS), clinical course and proper treatment strategies have not been well-established. Recently, immune-checkpoint inhibitors have shown potential efficacy in LPS. We aimed to describe the clinical course of LPS and evaluate the clinical impact of programmed death-ligand 1 (PD-L1).
Materials and Methods
We reviewed all consecutive patients (n=332) who underwent curative-intent surgery for localized LPS at Asan Medical Center between 1989 and 2017. PD-L1 testing was performed in well-differentiated and dedifferentiated LPS.
Results
The median age was 56 years with males comprising 60.8%. Abdomen-pelvis (47.6%) and well-differentiated (37.7%) were the most frequent primary site and histologic subtype, respectively. During a median follow-up of 81.2 months, recurrence was observed in 135 (40.7%), and 86.7% (117/135) were loco-regional. Well-differentiated subtype (hazard ratio [HR], 0.38), abdomen-pelvis origin (HR, 2.43), tumor size larger than 5 cm (HR, 1.83), positive resection margin (HR, 2.58), and postoperative radiotherapy (HR, 0.36) were significantly related with recurrence-free survival as well as visceral involvement (HR, 1.84) and multifocality (HR, 3.79) in abdomen-pelvis LPS. PD-L1 was positive in 31.5% (23/73) and 51.3% (39/76) of well-differentiated and dedifferentiated LPS, respectively, but had no impact on survival outcomes.
Conclusion
Clinical course of LPS was heterogeneous according to histology and anatomic location. Clear resection margin was important to lower recurrence and postoperative radiotherapy might have additional benefit. A decent portion of well-differentiated and dedifferentiated LPS were positive for PD-L1, but its prognostic role was unclear. Further research is needed to determine clinical implications of PD-L1, especially for advanced-stage LPS with unmet needs for effective systemic treatment.

Breast cancer

Comparison of the Effectiveness and Clinical Outcome of Everolimus Followed by CDK4/6 Inhibitors with the Opposite Treatment Sequence in Hormone Receptor-Positive, HER2-Negative Metastatic Breast Cancer: Hyehyun Jeong, Jae Ho Jeong, Jeong Eun Kim, Jin-Hee Ahn, Kyung Hae Jung, Sung-Bae Kim; Cancer Res Treat. 2022;54(2):469-477. Published online June 23, 2021; DOI: https://doi.org/10.4143/crt.2021.205

Abstract PDF Supplementary Material PubReader ePub

Purpose
In hormone receptor-positive, human epidermal growth factor receptor 2–negative metastatic breast cancer (HR+ HER2–MBC), the mainstay treatment options include cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) and everolimus (EVE) in combination with endocrine treatment. This study aims to compare the outcomes of the following treatment sequences: CDK4/6i followed by EVE and EVE followed by CDK4/6i.
Materials and Methods
Data from HR+ HER2– MBC patients treated between January 2014 and November 2020 with both CDK4/6i and EVE were retrospectively analyzed.
Results
Among the 88 patients included in the study, 51 received CDK4/6i before EVE (C→E group), and 37 received EVE before CDK4/6i (E→C group) with endocrine treatment. More patients in the E→C group had endocrine resistance (13.7% vs. 40.5%), experienced palliative chemotherapy (7.8% vs. 40.5%), and were heavily treated (treated as ≥ 3rd line, 5.9% vs. 40.5%). Median overall survival was 46.8 months in the C→E group and 38.9 months in the E→C group (p=0.151). Median composite progression-free survival (PFS), defined as the time from the start of the preceding regimen to disease progression on the following regimen or death, was 24.8 months in the C→E group vs. 21.8 months in the E→C group (p=0.681). Median PFS2/PFS1 ratio did not differ significantly between groups (0.5 in the C→E group, 0.6 in the E→C group; p=0.775). Ten patients (11.4%) discontinued EVE, and two patients (2.3%) discontinued CDK4/6i during treatment.
Conclusion
Although the CDK4/6i-based regimen should be considered as an earlier line of treatment, CDK4/6i- and EVE-based treatments can be valid options in circumstances where the other treatment had been already given.

Gastrointestinal cancer

A Phase II Study of Avelumab Monotherapy in Patients with Mismatch Repair–Deficient/Microsatellite Instability–High or POLE-Mutated Metastatic or Unresectable Colorectal Cancer: Jwa Hoon Kim, Sun Young Kim, Ji Yeon Baek, Yong Jun Cha, Joong Bae Ahn, Han Sang Kim, Keun-Wook Lee, Ji-Won Kim, Tae-You Kim, Won Jin Chang, Joon Oh Park, Jihun Kim, Jeong Eun Kim, Yong Sang Hong, Yeul Hong Kim, Tae Won Kim; Cancer Res Treat. 2020;52(4):1135-1144. Published online April 24, 2020; DOI: https://doi.org/10.4143/crt.2020.218

Abstract PDF Supplementary Material PubReader ePub

Purpose
We evaluated the efficacy and safety of avelumab, an anti-PD-L1 antibody, in patients with metastatic or unresectable colorectal cancer (mCRC) with mismatch repair deficiency (dMMR)/microsatellite instability-high (MSI-H) or POLE mutations.
Materials and Methods
In this prospective, open-label, multicenter phase II study, 33 patients with mCRC harboring dMMR/MSI-H or POLE mutations after failure of ≥1st-line chemotherapy received avelumab 10 mg/kg every 2 weeks. dMMR/MSI-H was confirmed with immunohistochemical staining (IHC) by loss of expression of MMR proteins or polymerase chain reaction (PCR) for microsatellite sequences. POLE mutation was confirmed by next-generation sequencing (NGS). The primary endpoint was the objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors ver. 1.1.
Results
The median age was 60 years, and 78.8% were male. Thirty patients were dMMR/MSI-H and three had POLE mutations. The ORR was 24.2%, and all of the responders were dMMR/MSI-H. For 21 patients with MSI-H by PCR or NGS, the ORR was 28.6%. At a median follow-up duration of 16.3 months, median progression-free survival and overall survival were 3.9 and 13.2 months in all patients, and 8.1 months and not reached, respectively, in patients with MSI-H by PCR or NGS. Dose interruption and discontinuation due to treatment-related adverse events occurred in 4 and 2 patients, respectively, with no treatment-related deaths.
Conclusion
Avelumab displayed antitumor activity with manageable toxicity in patients with previously treated mCRC harboring dMMR/MSI-H. Diagnosis of dMMR/MSI-H with PCR or NGS could be complementary to IHC to select patients who would benefit from immunotherapy.

Use of a High-Throughput Genotyping Platform (OncoMap) for RAS Mutational Analysis to Predict Cetuximab Efficacy in Patients with Metastatic Colorectal Cancer: Dalyong Kim, Yong Sang Hong, Jeong Eun Kim, Kyu-pyo Kim, Jae-Lyun Lee, Sung-Min Chun, Jihun Kim, Se Jin Jang, Tae Won Kim; Cancer Res Treat. 2017;49(1):37-43. Published online April 27, 2016; DOI: https://doi.org/10.4143/crt.2016.069

Abstract PDF PubReader ePub

Purpose
Cetuximab demonstrates improved efficacy outcomes in patients with metastatic colorectal cancer (mCRC) harboring wild-type KRAS exon 2. Resistance to cetuximab is mediated by activating less frequent mutations in the RAS genes beyond KRAS exon 2. We performed extended RASmutational analysis using a high -throughput genotyping platform (OncoMap) and evaluated extended RAS analysis for predicting cetuximab efficacy in patients harboring wild-type KRAS exon 2 tumors following Sanger sequencing.
Materials and Methods
Extended RAS analysis was performed on 227 wild-type KRAS exon 2 mCRC patients who received cetuximab as salvage treatment using OncoMap ver. 4.0. Targeted genes included exon 2, exon 3, and exon 4, both in KRAS and NRAS, and included BRAF exon 15. We assessed efficacy by the new RAS mutation status.
Results
The OncoMap detected 57 additional mutations (25.1%): 25 (11%) in KRAS exon 2 and 32 (14.1%) beyond KRAS exon 2. Survival differences were observed after dividing patients into the wild-type RAS group (n=170) and mutant RAS group (n=57) using OncoMap. Progression-free survival was 4.8 months versus 1.8 months (hazard ratio [HR], 0.44; 95% confidence interval [CI], 0.32 to 0.61), and overall survival was 11.9 months versus 8.4 months (HR, 0.65; 95% CI, 0.47 to 0.88).
Conclusion
Sanger sequencing is not sufficient for selecting candidates for cetuximab treatment. High-throughput extended RAS genotyping is a feasible approach for this purpose and identifies patients who might benefit from cetuximab treatment.

Given the promising activity of capecitabine and vinorelbine in metastatic breast cancer, this randomized phase II trial evaluated the efficacy and safety of this combination as neoadjuvant chemotherapy in breast cancer. Materials and Methods Patients with operable breast cancer (n=75) were randomly assigned to receive either four cycles of adriamycin 60 mg/m2 plus cyclophosphamide 600 mg/m2 every 3 weeks followed by four cycles of docetaxel 75 mg/m2 every 3 weeks (AC-D) or four cycles of capecitabine 2,000 mg/m2 (day 1-14) plus vinorelbine 25 mg/m2 (days 1 and 8) every 3 weeks followed by four cycles of docetaxel 75 mg/m2 (CV-D). The primary endpoint was pathologic complete response (pCR) in the primary breast (ypT0/is). Results Most patients (84%) had locally advanced (n=41) or inflammatory breast cancer (n=22). pCR rates in the primary breast were 15% (95% confidence interval [CI], 7% to 30%) and 11% (95% CI, 4% to 26%) in the AC-D and CV-D groups, respectively. The overall response rates and 5-year progression-free survival rates in the AC-D and CV-D groups were 62% and 64%, and 51.3% (95% CI, 34.6% to 68.0%) and 30.2% (95% CI, 13.3% to 47.1%), respectively. Although both regimens were well tolerated, CV-D showed less frequent grade 3-4 neutropenia and vomiting than AC-D, whereas manageable diarrhea and hand-foot syndrome were more common in the CV-D group. Conclusion CV-D is a feasible and active non-anthracycline–based neoadjuvant chemotherapy regimen for breast cancer.

Purpose

The objective of this study was to determine Bcl-2 expression in localized prostate cancer and its potential role as a predictive factor for biochemical recurrence (BCR).

Materials and Methods

This study included 171 Korean patients with newly diagnosed adenocarcinoma of the prostate who underwent radical prostatectomy (RP) without neoadjuvant therapy at a single center between February 2005 and May 2009. RP specimens obtained from these patients were analyzed for the expression of Bcl-2 using tissue microarray. The values of Bcl-2 and other clinicopathologic factors were evaluated. Statistical analysis was performed with contingency table analysis, chi-square tests, and a Cox proportional hazard model.

Results

Bcl-2 expression was immunohistologically-confirmed in 42 patients (24.6%). Bcl-2 expression was not associated with conventional clinicopathologic factors. Bcl-2 negative patients had a significantly longer mean BCR-free survival than Bcl-2-positive patients (p=0.036). Among several variables, a high Gleason score in the RP specimen (≥8), extraprostatic extension, seminal vesicle invasion (SVI), lymphovascular invasion (LVI), and Bcl-2 expression were significant predictors of BCR based on univariate analysis. Multivariate Cox proportional hazards analysis revealed that BCR was significantly associated with a high prostate specific antigen level (p=0.047), SVI (p<0.001), a positive surgical margin (p=0.004) and Bcl-2 expression (p=0.012).

Conclusion

Bcl-2 expression in RP specimens is associated with a significantly worse outcome, suggesting a potential clinical role for Bcl-2. Post-operative Bcl-2 could be a significant predictor of outcome after RP.

Abstract PDF PubReader ePub

Purpose

To assess the efficacy and safety of treating Korean patients with metastatic hormone-refractory prostate cancer (HRPC) using docetaxel plus prednisolone chemotherapy.

Materials and Methods

This was a retrospective cohort study performed in 98 patients with metastatic HRPC between October 2003 and April 2008. After screening, 72 patients fit the eligibility criteria for inclusion in this study. Treatment consisted of 5 mg prednisolone twice daily and 75 mg/m² docetaxel once every 3 weeks.

Results

Patient demographic characteristics included: median age 67 years (range, 51~86), median ECOG performance status 1 (0~2), Gleason score ≥8 in 61 patients (86%), and median serum PSA 45.5 ng/mL (range, 3.7~2,420.0). A total of 405 cycles of treatment were administered with a median 6 cycles (range, 1~20) per patient. The median docetaxel dose-intensity was 24.4 mg/m²/week (range, 17.5~25.6). A PSA response was seen in 51% of 63 evaluable patients at 12 weeks and maximal PSA decline ≥50% in 59% of 70 evaluable patients. Tumor response was evaluated in 13 patients, 4 patients achieved PR, and 5 patients had SD with a response rate of 31%. With a median follow-up duration of 23.1 months (95%CI, 16.7~29.5), the median time to PSA progression was 5.1 months (95%CI, 4.5~5.8) and median overall survival was 22.8 months (95%CI, 16.6~29.1). Nine (13%) patients experienced grade 3 or higher febrile neutropenia.

Conclusion

This chemotherapy regimen (docetaxel every 3 weeks plus prednisolone daily) demonstrated a strong response in Korean patients with metastatic HRPC, while the toxicity profile was manageable and similar to that observed in Western patients.
