Analysis of T Cell Subsets Using Multiplex Immunohistochemistry and Clinical Outcomes of Immune Checkpoint Inhibitors in Advanced Gastric Cancer Patients: Tae-Yong Kim, Jeesun Yoon, Dae-Won Lee, Yoonjin Kwak, Hye Seung Lee, Do-Youn Oh; Received April 28, 2025 Accepted September 7, 2025 Published online September 9, 2025; DOI: https://doi.org/10.4143/crt.2025.458 [Accepted]

Abstract PDF: Purpose
As immunotherapy has become essential in the treatment of gastric cancer (GC), there has been growing interest in T-cells, which play a key role in immunotherapy. In this study, we evaluated the impact of T-cell subsets on immune responsiveness to immune checkpoint inhibitors (ICIs) in GC using multiplex immunohistochemistry (mIHC).
Materials and Methods
Eighty-four GC patients treated with ICIs were enrolled, and we repeated the staining-scanning-stripping procedure nine times to assess different kinds of T-cells or cell-surface immune checkpoints in a single tissue section.
Results
The proportions of patients with microsatellite instability-high (MSI-H), Epstein-Barr virus (EBV), and non-MSI/non-EBV were 8.3%, 3.6% and 88.1%. A high cytotoxic T-cell (T_cyto) density was related to longer overall survival (OS). GC with a high ratio of T_cyto/total T-cells (T_total) and a low ratio of regulatory T-cells (T_reg)/T_total showed better OS. A high density of PD-1- or TIM-3- expressing T_cyto were also associated with longer OS than a low density of those. Among memory T-cells (T_mem) subsets, GC with a high ratio of memory T_cyto/T_mem and a low ratio of memory T_reg/T_mem showed prolonged OS. Better tumor responses were observed in GC with a high ratio of T_cyto/T_total and memory T_cyto/T_mem.
Conclusion
T-cell subsets within the tumor microenvironment were associated with the clinical efficacy of ICIs in GC. PD-1- or TIM-3 expressing T-cells were also associated with response to ICIs, while memory T-cells subsets were associated with survival. mIHC is a feasible method for evaluating T-cell subsets in archival gastric tumor tissue.

DNA damage and Nuclear Anaplasia Induced by Trastuzumab Deruxtecan in Cancer Cells with Variable HER2 Expression and Homologous Recombination Deficiency Status: So Hyeon Kim, Yoonjung Park, Ahrum Min, Hye Yeon Park, Yu-Jin Kim, Sujin Ham, Jiwon Koh, Seongyeong Kim, Dae-Won Lee, Han Suk Ryu, Jin-Soo Kim, Kyung-Hun Lee, Seock-Ah Im; Received February 21, 2025 Accepted June 2, 2025 Published online August 4, 2025; DOI: https://doi.org/10.4143/crt.2025.201 [Accepted]

Purpose
Human epidermal growth factor receptor 2 (HER2) is amplified or overexpressed in various malignancies, including breast and gastric cancers, and is associated with poor prognosis. Although HER2-targeted therapies, such as trastuzumab, improve outcomes in HER2-positive tumors, resistance often develops, and HER2-low tumors remain largely untargeted. Trastuzumab deruxtecan (T-DXd; DS-8201a) is a HER2-targeted antibody-drug conjugate with potent activity in HER2-positive and HER2-low tumors. This study evaluates its antitumor mechanisms and efficacy in HER2-positive, HER2-low, and homologous recombination deficiency (HRD)-associated models.
Materials and Methods
Effects of T-DXd were assessed in cancer cell lines with diverse HER2 expression and HRD status. In vivo efficacy was evaluated using a xenograft model derived from HER2-low SNU-601 gastric cancer cells.
Results
T-DXd reduced HER2 phosphorylation and downstream signaling (AKT, ERK) in HER2-positive cells. It induced DNA damage accumulation, as evidenced by increased γH2AX and p-Chk1 expression, and triggered apoptosis through cleaved PARP and caspase-3 activation, confirmed by annexin V staining. Similar effects were observed in HER2-low cells, with greater sensitivity in HRD cells. In xenografts, T-DXd reduced tumor volume by up to 80% at 4 mg/kg and 10 mg/kg. Histological analyses showed decreased Ki-67 and increased apoptosis. Furthermore, T-DXd induced G2/M cell cycle arrest and nuclear anaplasia, suggesting disruption of chromosomal stability as a potential antitumor mechanism. No significant toxicity, including body weight loss, was observed.
Conclusion
These findings highlight T-DXd’s effectiveness in HER2-low and HRD tumors, supporting its broader clinical application, including strategies targeting DNA damage repair pathways.

Elimusertib, a Novel ATR Inhibitor, Induces Anti-tumor Effects through Replication Catastrophe in Breast Cancers: Mudong Kim, Ahrum Min, Sohyeon Kim, Seongyeong Kim, Yu-jin Kim, Sujin Ham, Miso Lee, Eunice Yoojin Lee, Jinyong Kim, Dae-Won Lee, Kyung-Hun Lee, Seock-Ah Im; Cancer Res Treat. 2026;58(1):159-174. Published online April 7, 2025; DOI: https://doi.org/10.4143/crt.2024.1105

Abstract PDF Supplementary Material PubReader ePub

Purpose
Sustained cell proliferation and cell cycle acceleration in cancer cells inherently increase DNA damage, which interferes with homeostatic replication and transcription. Ataxia telangiectasia and Rad3-related (ATR) is crucial for initiation of the DNA damage response, and ATR inhibitors, such as elimusertib, induce increased replication stress and DNA damage. We investigated the anti-tumor effects of elimusertib and its mechanism of action in relation to replication stress.
Materials and Methods
Anti-tumor effects were evaluated by MTT assay and colony formation assay in breast cancer cell lines in vitro, in breast cancer cell xenografts in vivo, and in patient-derived xenograft models. Cell cycle was assessed by flow cytometry and BrdU assay was used to measure replicating cells and S-phase progression. Alkaline and neutral comet assay was used to measure single and double-stranded DNA damages, respectively.
Results
Elimusertib delayed S-phase progression in MDA-MB-453 and MDA-MB-231 cells and induced caspase-7–dependent apoptosis. Furthermore, the increase in sub-G1 population in the fluorescence-activated cell sorting analysis and Annexin V assay also confirmed apoptotic cell death. In the BrdU assay, single-stranded DNA (ssDNA) increased in sensitive cells and aberrant ssDNA induced DNA damage in S-phase and eventually caused replication catastrophe. Finally, these anti-tumor effects were proven in in vivo xenograft and patient-derived xenograft models.
Conclusion
Elimusertib had anti-tumor effects and induced replication catastrophe in breast cancer cells with a high replication rate. Moreover, cells under high DNA replication stress were sensitive to elimusertib. Further studies and treatment strategies with elimusertib are warranted for cancers with a high replication rate.

Purpose
Considering the high disease burden and unique features of Asian patients with breast cancer (BC), it is essential to have a comprehensive view of genetic characteristics in this population. An institutional targeted sequencing platform was developed through the Korea Research-Driven Hospitals project and was incorporated into clinical practice. This study explores the use of targeted next-generation sequencing (NGS) and its outcomes in patients with advanced/metastatic BC in the real world.
Materials and Methods
We reviewed the results of NGS tests administered to BC patients using a customized sequencing platform—FiRST Cancer Panel (FCP)—over 7 years. We systematically described clinical translation of FCP for precise diagnostics, personalized therapeutic strategies, and unraveling disease pathogenesis.
Results
NGS tests were conducted on 548 samples from 522 patients with BC. Ninety-seven point six percentage of tested samples harbored at least one pathogenic alteration. The common alterations included mutations in TP53 (56.2%), PIK3CA (31.2%), GATA3 (13.8%), BRCA2 (10.2%), and amplifications of CCND1 (10.8%), FGF19 (10.0%), and ERBB2 (9.5%). NGS analysis of ERBB2 amplification correlated well with human epidermal growth factor receptor 2 immunohistochemistry and in situ hybridization. RNA panel analyses found potentially actionable and prognostic fusion genes. FCP effectively screened for potentially germline pathogenic/likely pathogenic mutation. Ten point three percent of BC patients received matched therapy guided by NGS, resulting in a significant overall survival advantage (p=0.022), especially for metastatic BCs.
Conclusion
Clinical NGS provided multifaceted benefits, deepening our understanding of the disease, improving diagnostic precision, and paving the way for targeted therapies. The concrete advantages of FCP highlight the importance of multi-gene testing for BC, especially for metastatic conditions.

Recent Developments in the Therapeutic Landscape of Advanced or Metastatic Hormone Receptor–Positive Breast Cancer: Eunice Yoojin Lee, Dae-Won Lee, Kyung-Hun Lee, Seock-Ah Im; Cancer Res Treat. 2023;55(4):1065-1076. Published online October 5, 2023; DOI: https://doi.org/10.4143/crt.2023.846

Abstract PDF PubReader ePub

Hormone receptor–positive (HR+) disease is the most frequently diagnosed subtype of breast cancer. Among tumor subtypes, natural course of HR+ breast cancer is indolent with favorable prognosis compared to other subtypes such as human epidermal growth factor protein 2–positive disease and triple-negative disease. HR+ tumors are dependent on steroid hormone signaling and endocrine therapy is the main treatment option. Recently, the discovery of cyclin-dependent kinase 4/6 inhibitors and their synergistic effects with endocrine therapy has dramatically improved treatment outcome of advanced HR+ breast cancer. The demonstrated efficacy of additional nonhormonal agents, such as targeted therapy against mammalian target of rapamycin and phosphatidylinositol 3-kinase signaling, poly(ADP-ribose) polymerase inhibitors, antibody-drug conjugates, and immunotherapeutic agents have further expanded the available therapeutic options. This article reviews the latest advancements in the treatment of HR+ breast cancer, and in doing so discusses not only the development of currently available treatment regimens but also emerging therapies that invite future research opportunities in the field.

A Multicenter, Prospective, Observational Study to Evaluate Ethanol-Induced Symptoms in Patients Receiving Docetaxel Chemotherapy: Young-Woong Won, Jin-Hyoung Kang, Jung Hye Kwon, Dong-Hoe Koo, Jung Hun Kang, Chi Hoon Maeng, Hee Kyung Ahn, Sung Yong Oh, Dae-Won Lee, Joohyuk Sohn, So Yeon Oh, Kyung Hee Lee, Su-Jin Koh, Keun Seok Lee, Chan-Kyu Kim, Ji-Yeon Kim, Jun Ho Ji, Sung-Bae Kim, Joo Young Ha, Ho Young Kim; Cancer Res Treat. 2023;55(4):1096-1103. Published online April 7, 2023; DOI: https://doi.org/10.4143/crt.2022.1565

Abstract PDF Supplementary Material PubReader ePub

Purpose
Several previous studies and case reports have reported ethanol-induced symptoms in patients receiving anticancer drugs containing ethanol. Most docetaxel formulations contain ethanol as a solvent. However, there are insufficient data on ethanol-induced symptoms when docetaxel-containing ethanol is administered. The primary purpose of this study was to investigate the frequency and pattern of ethanol-induced symptoms during and after docetaxel administration. The secondary purpose was to explore the risk factors for ethanol-induced symptoms.
Materials and Methods
This was a prospective, multicenter, observational study. The participants filled out ethanol-induced symptom questionnaire on the day of chemotherapy and the following day.
Results
Data from 451 patients were analyzed. The overall occurrence rate of ethanol-induced symptoms was 44.3% (200/451 patients). The occurrence rate of facial flushing was highest at 19.7% (89/451 patients), followed by nausea in 18.2% (82/451 patients), and dizziness in 17.5% (79/451 patients). Although infrequent, unsteady walking and impaired balance occurred in 4.2% and 3.3% of patients, respectively. Female sex, presence of underlying disease, younger age, docetaxel dose, and docetaxel-containing ethanol amount were significantly associated with the occurrence of ethanol-induced symptoms.
Conclusion
The occurrence of ethanol-induced symptoms was not low in patients receiving docetaxel-containing ethanol. Physicians need to pay more attention to the occurrence of ethanol-induced symptoms and prescribe ethanol-free or low-ethanol-containing formulations to high-risk patients.

Circulating Tumor DNA Dynamics and Treatment Outcome of Regorafenib in Metastatic Colorectal Cancer: Dae-Won Lee, Yoojoo Lim, Hwang-Phill Kim, Su Yeon Kim, Hanseong Roh, Jun-Kyu Kang, Kyung‑Hun Lee, Min Jung Kim, Seung-Bum Ryoo, Ji Won Park, Seung-Yong Jeong, Kyu Joo Park, Gyeong Hoon Kang, Sae-Won Han, Tae-You Kim; Cancer Res Treat. 2023;55(3):927-938. Published online March 7, 2023; DOI: https://doi.org/10.4143/crt.2023.268

Abstract PDF Supplementary Material PubReader ePub

Purpose
Circulating tumor DNA (ctDNA) is emerging as a valuable non-invasive tool to identify tumor heterogeneity and tumor burden. This study investigated ctDNA dynamics in metastatic colorectal cancer patients treated with regorafenib.
Materials and Methods
In this prospective biomarker study, plasma cell-free DNA (cfDNA) samples obtained at baseline, at the first response evaluation after 2 cycles of treatment, and at the time of progressive disease were sequenced using a targeted next-generation sequencing platform which included 106 genes.
Results
A total of 285 blood samples from 110 patients were analyzed. Higher baseline cfDNA concentration was associated with worse progression-free survival (PFS) and overall survival (OS). After 2 cycles of treatment, variant allele frequency (VAF) in the majority of ctDNA mutations decreased with a mean relative change of –31.6%. Decreases in the VAF of TP53, APC, TCF7L2, and ROS1 after 2 cycles of regorafenib were associated with longer PFS. We used the sum of VAF at each time point as a surrogate for the overall ctDNA burden. A reduction in sum (VAF) of ≥ 50% after 2 cycles was associated with longer PFS (6.1 vs. 2.7 months, p=0.002), OS (11.3 vs. 5.9 months, p=0.001), and higher disease control rate (86.3% vs. 51.1%, p < 0.001). VAF of the majority of the ctDNA mutations increased at the time of disease progression, and VAF of BRAF increased markedly.
Conclusion
Reduction in ctDNA burden as estimated by sum (VAF) could be used to predict treatment outcome of regorafenib.

Published online November 8, 2022; DOI: https://doi.org/10.4143/crt.2022.1360

Abstract PDF PubReader ePub

Purpose
This single-arm phase II trial investigate the efficacy and safety of S-1 plus oxaliplatin (SOX) in patients with metastatic breast cancer.
Materials and Methods
Patients with metastatic breast cancer previously treated with anthracyclines and taxanes were enrolled. Patients received S-1 (40-60 mg depending on patient’s body surface area, twice a day, day 1-14) and oxaliplatin (130 mg/m2, day 1) in 3 weeks cycle until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumor 1.1. Secondary endpoints included time-to-progression (TTP), duration-of-response (DoR), overall survival (OS), and adverse events.
Results
A total of 87 patients were enrolled from 11 institutions in Korea. Hormone receptor was positive in 54 (62.1%) patients and six (6.9%) had human epidermal growth factor receptor 2–positive disease. Forty-eight patients (85.1%) had visceral metastasis and 74 (55.2%) had more than three sites of metastases. The ORR of SOX regimen was 38.5% (95% confidence interval [CI], 26.9 to 50.0) with a median TTP of 6.0 months (95% CI, 5.1 to 6.9). Median DoR and OS were 10.3 months (95% CI, 5.5 to 15.1) and 19.4 (95% CI, not estimated) months, respectively. Grade 3 or 4 neutropenia was reported in 28 patients (32.1%) and thrombocytopenia was observed in 23 patients (26.6%).
Conclusion
This phase II study showed that SOX regimen is a reasonable option in metastatic breast cancer previously treated with anthracyclines and taxanes.

Abstract PDF Supplementary Material PubReader ePub

Purpose
To provide a wider choice of treatment opportunities for patients with neuroendocrine tumor (NET) in Korea, we have conducted a phase 1, open-label, single-arm, dose-escalation study of SNU-KB-01, a no-carrier added (NCA) ¹⁷⁷Lu-labeled DOTATATE.
Materials and Methods
Seven patients with inoperable, progressive, metastatic, or locally advanced, somatostatin receptor-positive NET with Ki67 index ≤ 20% were enrolled according to the rolling six design. The study consisted of two cohorts to receive 4 cycles of SNU-KB-01 every 8 weeks for the first dose of 5.55 GBq (n=3) and 7.40 GBq (n=4). We assessed the incidence of dose-limiting toxicity (DLT) and adverse event, absorbed dose of kidneys and bone marrow, and objective tumor response.
Results
Seven patients completed 4 cycles (21.3-30.1 GBq total dose) of SNU-KB-01. The mean absorbed doses to kidneys and bone marrow were 0.500 mGy/MBq and 0.053 mGy/MBq, respectively, and the total body effective dose was 0.115 mSv/MBq. No DLT was observed and the maximum tolerated dose was 7.40 GBq/cycle. Grade 3 thrombocytopenia occurred in one patient, but no other grade 3 or 4 major hematologic or renal toxicity was observed. The best objective response to SNU-KB-01 was partial response. Overall response rate was 42.9% and disease control rate was 85.7%.
Conclusion
Treatment with 4 cycles of SNU-KB-01 was well tolerated and resulted in control of disease in most of the patients. Our results indicate SNU-KB-01, an NCA ¹⁷⁷Lu-labeled DOTATATE, as a potentially safe and efficacious treatment option for NET patients in Korea.

Abstract PDF PubReader ePub

Purpose
We aimed to assess the real-world efficacy of nab-paclitaxel in metastatic breast cancer patients.
Materials and Methods
This is a retrospective study performed in two tertiary referral hospitals in Korea. Patients with metastatic breast cancer treated with nab-paclitaxel (Abraxane®) between March 2016 and March 2020 were enrolled.
Results
A total of 102 patients with metastatic breast cancer were included. Patients were heavily pre-treated with a median of four prior lines of chemotherapy (5 lines when including endocrine therapy in hormone-receptor-positive patients), and 66 patients (64.7%) were exposed to taxanes in the metastatic setting. According to St. Gallen molecular subtypes, 36 patients (35.3%) were luminal A, 28 (27.5%) were luminal B, 18 (17.7%) were human epidermal growth factor receptor 2–positive and 20 (19.6%) had triple-negative disease. Fifty patients (49.0%) were treated with a 3-weekly regimen (260 mg/m² on day 1 every 3 weeks), and 52 (51.0%) were treated with a weekly regimen (100 mg/m² every week). Objective response rate was 22.9%. After a median follow-up of 22.0 months, median progression-free survival (PFS) was 4.0 months (95% confidence interval [CI], 2.6 to 4.8) and median overall survival was 8.7 months (95% CI, 7.5 to 11.2). Patients treated with weekly regimen had longer PFS compared to 3-weekly regimen (5.5 vs. 2.3 months, p < 0.001). Multivariate analysis revealed the treatment regimen as an independent prognostic factor for PFS. There was no grade 3 or 4 hypersensitivity reaction.
Conclusion
This real-world data shows that nab-paclitaxel is a reasonable treatment option in heavily pre-treated and/or taxane-exposed metastatic breast cancer patients.

Published online September 23, 2020; DOI: https://doi.org/10.4143/crt.2020.430

Abstract PDF Supplementary Material PubReader ePub

Purpose
This study investigated the association of insulin, metformin, and statin use with survival and whether the association was modified by the hormone receptor status of the tumor in patients with breast cancer.
Materials and Methods
We studied 7,452 patients who had undergone surgery for breast cancer at Seoul National University Hospital from 2008 to 2015 using the nationwide claims database. Exposure was defined as a recorded prescription of each drug within 12 months before the diagnosis of breast cancer.
Results
Patients with prior insulin or statin use were more likely to be older than 50 years at diagnosis and had a higher comorbidity index than those without it (p < 0.01 for both). The hazard ratio (HR) for death with insulin use was 5.7 (p < 0.01), and the effect was attenuated with both insulin and metformin exposure with an HR of 1.2 (p=0.60). In the subgroup analyses, a heightened risk of death with insulin was further prominent with an HR of 17.9 (p < 0.01) and was offset by co-administration of metformin with an HR of 1.3 (p=0.67) in patients with estrogen receptor (ER)–negative breast cancer. Statin use was associated with increased overall mortality only in patients with ER-positive breast cancer with HR for death of 1.5 (p=0.05).
Conclusion
Insulin or statin use before the diagnosis of breast cancer was associated with an increase in all-cause mortality. Subsequent analyses suggested that metformin or statin use may have been protective in patients with ER-negative disease, which warrants further studies.

CA19-9 or CEA Decline after the First Cycle of Treatment Predicts Survival in Advanced Biliary Tract Cancer Patients Treated with S-1 and Cisplatin Chemotherapy: Dae-Won Lee, Seock-Ah Im, Yu Jung Kim, Yaewon Yang, Jiyoung Rhee, Im Il Na, Kyung-Hun Lee, Tae-Yong Kim, Sae-Won Han, In Sil Choi, Do-Youn Oh, Jee Hyun Kim, Tae-You Kim, Yung-Jue Bang; Cancer Res Treat. 2017;49(3):807-815. Published online January 18, 2017; DOI: https://doi.org/10.4143/crt.2016.326

Abstract PDF PubReader ePub

Purpose
While tumor markers (carbohydrate antigen 19-9 [CA 19-9] and carcinoembryonic antigen [CEA]) can aid in the diagnosis of biliary tract cancer, their prognostic role has not been clearly elucidated. Therefore, this study was conducted to evaluate the prognostic role of tumor markers and tumor marker change in patients with advanced biliary tract cancer.
Materials and Methods
Patients with pathologically proven metastatic or relapsed biliary tract cancer who were treated in a phase II trial of first-line S-1 and cisplatin chemotherapy were enrolled. Serum tumor markers were measured at baseline and after the first cycle of chemotherapy.
Results
Among a total of 104 patients, 80 (77%) had elevated baseline tumor markers (69 with CA 19-9 elevation and 40 with CEA). A decline ≥ 30% of the elevated tumor marker level after the first cycle of chemotherapy conferred an improved time to progression (TTP), overall survival (OS), and better chemotherapy response. Multivariate analysis revealed tumor marker decline as an independent positive prognostic factor of TTP (adjusted hazard ratio [HR], 0.44; p=0.003) and OS (adjusted HR, 0.37; p < 0.001). Subgroup analysis revealed similar results in each group of patients with CA 19-9 elevation and CEA elevation. In addition, elevated baseline CEA was associated with poor survival in both univariate and multivariate analysis.
Conclusion
Tumor marker decline was associated with improved survival in biliary tract cancer. Measuring tumor marker after the first cycle of chemotherapy can be used as an early assessment of treatment outcome.

Splenomegaly and Its Associations with Genetic Polymorphisms and Treatment Outcome in Colorectal Cancer Patients Treated with Adjuvant FOLFOX: Mi-Jung Kim, Sae-Won Han, Dae-Won Lee, Yongjun Cha, Kyung-Hun Lee, Tae-Yong Kim, Do-Youn Oh, Se Hyung Kim, Seock-Ah Im, Yung-Jue Bang, Tae-You Kim; Cancer Res Treat. 2016;48(3):990-997. Published online January 14, 2016; DOI: https://doi.org/10.4143/crt.2015.296

Abstract PDF Supplementary Material PubReader ePub

Purpose
Splenomegaly is a clinical surrogate of oxaliplatin-induced sinusoidal obstruction syndrome (SOS). We investigated development of splenomegaly and its association with treatment outcome and genetic polymorphisms following adjuvant 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) in colorectal cancer (CRC) patients.
Materials and Methods
Splenomegaly was determined by spleen volumetry using computed tomography images obtained before initiation of chemotherapy and after completion of adjuvant FOLFOX in CRC patients. Ten genetic polymorphisms in 4 SOS-related genes (VEGFA, MMP9, NOS3, and GSTP1) were analyzed using DNA from peripheral blood mononuclear cells.
Results
Of 124 patients included, increase in spleen size was observed in 109 (87.9%). Median change was 31% (range, –42% to 168%). Patients with splenomegaly had more severe thrombocytopenia compared to patients without splenomegaly during the chemotherapy period (p < 0.0001). The cumulative dose of oxaliplatin and the lowest platelet count during the chemotherapy period were clinical factors associated with splenomegaly. However, no significant associations were found between genetic polymorphisms and development of splenomegaly. Disease-free survival was similar regardless of the development of splenomegaly.
Conclusion
Splenomegaly was frequently observed in patients receiving adjuvant FOLFOX and resulted in more severe thrombocytopenia but did not influence treatment outcome. Examined genetic polymorphisms did not predict development of splenomegaly.

Abstract PDF PubReader ePub

Adenoid cystic carcinoma (ACC) of the breast is a very rare and indolent tumor with a favorable prognosis, despite its triple-negative status. Due to its rarity, there has been no consensus regarding treatments, and treatment guidelines have not been established. Here, we report on six patients with ACC of the breast. All of the patients initially presented with localized disease and no axillary lymph node metastases. Although some of our patients developed local recurrence or distant metastases, all patients had a favorable clinical course, and to date, none of the patients has died from complications of her disease. Here, we described the clinicopathologic features of ACC of the breast and review the current literature.
