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.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
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.

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

AbstractAbstract PDFSupplementary MaterialPubReaderePub
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.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
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.

DOI: https://doi.org/10.4143/crt.2017.562
AbstractAbstract PDFPubReaderePub
Purpose
We investigated whether irinotecan plus capecitabine improved progression-free survival (PFS) compared with capecitabine alone in patients with human epidermal growth factor 2 (HER2) negative and anthracycline and taxane pretreated metastatic breast cancer (MBC).
Materials and Methods
A total of 221 patients were randomly assigned to irinotecan (80 mg/m2, days 1 and 8) and capecitabine (1,000 mg/m2 twice a day, days 1-14) or capecitabine alone (1,250 mg/m2 twice a day, days 1-14) every 3 weeks. The primary endpoint was PFS.
Results
There was no significant difference in PFS between the combination and monotherapy arm (median, 6.4 months vs. 4.7 months; hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63 to 1.11; p=0.84). In patients with triple-negative breast cancer (TNBC, n=90), the combination significantly improved PFS (median, 4.7 months vs. 2.5 months; HR, 0.58; 95% CI, 0.37 to 0.91; p=0.02). Objective response rate was numerically higher in the combination arm, though it failed to reach statistical significance (44.4% vs. 33.3%, p=0.30). Overall survival did not differ between arms (median, 20.4 months vs. 24.0 months; p=0.63). While grade 3 or 4 neutropenia was more common in the combination arm (39.6% vs 9.0%), hand-foot syndrome was more often observed in capecitabine arm. Quality of life measurements in global health status was similar. However, patients in the combination arm showed significantly worse symptom scales especially in nausea/vomiting and diarrhea.
Conclusion
Irinotecan plus capecitabine did not prove clinically superior to single-agent capecitabine in anthracycline- and taxane-pretreated HER2 negative MBC patients. Toxicity profiles of the two groups differed but were manageable. The role of added irinotecan in patients with TNBC remains to be elucidated.

AbstractAbstract PDFPubReaderePub
Purpose
This nationwide retrospective study was conducted to evaluate the efficacy and safety of combined gemcitabine and docetaxel (GD) as an off-label therapy for advanced soft tissue sarcoma, which has limited treatment options owing to its rare occurrence.
Materials and Methods
A total of 228 patients received GD therapy for advanced soft tissue sarcoma from 2009 to 2014 in Korea. We retrospectively reviewed the clinical medical records and claims data of these patients.
Results
A total of 218 patients in 20 medical centers were included in the final analysis (median age, 50.0 years). The objective response rate was 15.1% (34/218, in the leiomyosarcoma subgroup; 26.3%). The median overall survival and progression-free survival were 10.3 months (95% confidence interval [CI], 8.4 to 12.2) and 3.3 months (95% CI, 2.8 to 4.7), respectively. The treatment was discontinued in 7.8% of patients owing to adverse events; however, there was no adverse event-related death. Neutropenia (35.7%) and anemia (15.1%) were the most frequent grade 3/4 toxicities. Univariate analysis for identifying the predictors of the progression-free survival period revealed that patients aged ≤ 50 years had a hazard ratio of 1.388 (95% CI, 1.027 to 1.875; p < 0.05) relative to those aged > 50 years, and the group with leiomyosarcoma had a hazard ratio of 0.693 (95% CI, 0.493 to 0.975; p < 0.05) relative to the group with other histopathological subtypes.
Conclusion
GD therapy was tolerable and effective for Korean patients with soft tissue sarcoma. In conclusion, for patients with advanced soft tissue sarcoma, especially leiomyosarcoma, GD therapy could be an important therapeutic option.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
Purpose
The purpose of this study is to investigate the prognostic value of lymph node (LN) ratio (LNR) in patients with breast cancer after neoadjuvant chemotherapy.
Materials and Methods
This retrospective analysis is based on the data of 814 patientswith stage II/III breast cancer treated with four cycles of doxorubicin/cyclophosphamide followed by four cycles of docetaxel before surgery. We evaluated the clinical significance of LNR (3 categories: low 0-0.20 vs. intermediate 0.21-0.65 vs. high 0.66-1.00) using a Cox proportional regression model.
Results
A total of 799 patients underwent breast surgery. Pathologic complete response (pCR, ypT0/isN0) was achieved in 129 patients (16.1%) (hormone receptor [HR] +/human epidermal growth factor receptor 2 [HER2] –, 34/373 [9.1%]; HER2+, 45/210 [21.4%]; triple negative breast cancer, 50/216 [23.1%]). The mean numbers of involved LN and retrieved LN were 2.70 (range, 0 to 42) and 13.98 (range, 1 to 64), respectively. The mean LNR was 0.17 (low, 574 [71.8%]; intermediate, 170 [21.3%]; high, 55 [6.9%]). In univariate analysis, LNR showed significant association with a worse relapse-free survival (3-year relapse-free survival rate 84.8% in low vs. 66.2% in intermediate vs. 54.3% in high; p < 0.001, log-rank test). In multivariate analysis, LNR did not show significant association with recurrence after adjusting for other clinical factors (age, histologic grade, subtype, ypT stage, ypN stage, lymphatic or vascular invasion, and pCR). In subgroup analysis, the LNR system had good prognostic value in HR+/HER2– subtype.
Conclusion
LNR is not superior to ypN stage in predicting clinical outcome of breast cancer after neoadjuvant chemotherapy. However, the prognostic value of the LNR system in HR+/HER2– patients is notable and worthy of further investigation.

AbstractAbstract PDFPubReaderePub
Purpose
This study analyzed the role of plasma biomarkers for TSU-68 in a previous phase II trial comparing TSU-68 plus docetaxel and docetaxel alone in patients with metastatic breast cancer.
Materials and Methods
A total of 77 patients were eligible for this study (38 in the TSU-68 plus docetaxel arm and 39 in the docetaxel alone arm). Blood samples were collected prior to the start of each cycle, and vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF)- AA, -AB, -BB, fibroblast growth factor, M30, C-reactive protein (CRP), and interleukin 6 (IL-6) levels were measured using enzyme linked immunosorbent assay. The primary endpoint was progression-free survival (PFS).
Results
In patients with baseline PDGF-AA ≥ median, median PFS was significantly worse in the TSU-68 plus docetaxel group than in the docetaxel alone group (5.4 months vs. 13.7 months, p=0.049), while a trend toward a PFS benefit was observed in those with baseline PDGF-AA < median (9.7 months vs. 4.0 months, p=0.18; p for interaction=0.03). In the TSU-68 plus docetaxel group, PFS showed significant association with fold changes in CRP (p=0.001), IL-6 (p < .001), PDGF-BB (p=0.02), and VEGF (p=0.047) following the first treatment cycle.
Conclusion
Baseline PDGF-AA levels and dynamics of VEGF, PDGF-BB, CRP, and IL-6 levels were predictive for the efficacy of TSU-68.

AbstractAbstract PDFPubReaderePub
Purpose
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.

AbstractAbstract PDFPubReaderePub
Purpose
The purpose of this study is to assess the efficacy and safety of everolimus in Korean patients with metastatic renal cell carcinoma (mRCC) for whom initial treatment with a vascular endothelial growth factor receptor-tyrosine kinase inhibitor (VEGFr-TKI) has failed. Materials and Methods Eligible patients with mRCC (any histology) who had progressed on or were intolerant of VEGFr-TKI therapy received oral everolimus (10 mg dose once daily). Tumor response was reassessed according to Response Evaluation Criteria in Solid Tumors (RECIST). Results This study included 100 patientswith a median follow-up duration of 10.2 months, a median progression-free survival (PFS) of 4.2 months (95% confidence interval [CI], 3.4 to 5.0 months), and an overall survival of 10.1 months (95% CI, 6.9 to 13.3 months). The most common grade 3 or greater adverse events (AEs) overall were anemia (13%), pneumonitis (9%), hyperglycemia (8%), and stomatitis (6%). While the incidence of pneumonitis was similar (26 cases, 26%) to the reported incidence in Western patients, the Korean presentations were more severe: 10 patients permanently discontinued everolimus due to pneumonitis, including two deaths on treatment. Statistically significant relationships were established between biologic toxicities, hyperglycemia and anemia, and PFS (hyperglycemia vs. non-hyperglycemia: hazard ratio [HR], 0.61; p=0.055 and anemia vs. non-anemia: HR, 0.51; p=0.021). Conclusion Everolimus was effective in Korean patients with mRCC who had failed initial VEGFr-TKI therapy. While everolimus was well tolerated in general and the AE incidence of this study was similar to those of previous reports, severe pneumonitis was common. Hyperglycemia and anemia showed significant correlation with PFS and thus may be potentially useful as prognostic indicators.

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.

Purpose

The benefit of consolidation high-dose chemotherapy (HDC) for high-risk primary breast cancer is controversial. We evaluated the efficacy and safety of consolidation HDC with cyclophosphamide, thiotepa and carboplatin (CTCb) followed by autologous stem-cell transplantation (ASCT) in resected breast cancer patients with 10 or more positive lymph nodes.

Materials and Methods

Between December 1994 and April 2000, 22 patients were enrolled. All patients received 2 to 6 cycles of adjuvant chemotherapy after surgery for breast cancer. The HDC regimen consisted of cyclophosphamide 1,500 mg/m2/day, thiotepa 125 mg/m2/day and carboplatin 200 mg/m2/day intravenous for 4 consecutive days.

Results

With a median follow-up of 58 months, 11 patients recurred and died. The median disease-free survival (DFS) and median overall survival (OS) were 49 and 69 months, respectively. The 5-year DFS and OS rates were 50% and 58%, respectively. The 12 patients with 10 to 18 involved nodes had better 5-year DFS (67%) and OS (75%) than 10 patients with more than 18 involved nodes (30% and 38%, respectively). The most common grade 3 or 4 nonhematologic toxicity was diarrhea, which occurred in 5 patients (23%). No treatment-related death was observed.

Conclusion

Consolidation HDC with CTCb followed by ASCT for resected breast cancer with more than 10 positive nodes had an acceptable toxicity but does not show promising survival.

AbstractAbstract PDFPubReaderePub
Purpose

The benefit of high-dose chemotherapy (HDC) for metastatic breast cancer (MBC) is controversial. We evaluated the efficacy and safety of HDC with cyclophosphamide, thiotepa, and carboplatin (CTCb) followed by autologous stem-cell transplantation (ASCT) for MBC patients.

Materials and Methods

From September 1994 to December 1999, 23 MBC patients were enrolled. All the patients received 2 to 10 cycles of induction chemotherapy. Before transplantation, 12 patients were in complete response (CR), nine were in partial response (PR), and two had progressive disease (PD). The HDC regimen consisted of cyclophosphamide 1,500 mg/m2/day, thiotepa 125 mg/m2/day and carboplatin 200 mg/m2/day intravenously for 4 consecutive days.

Results

After ASCT, 13 patients (56%) had a CR, five (22%) had a PR, three (13%) had no change, while two (9%) showed a PD. Seventeen patients relapsed or progressed during the median follow-up of 78 months. The median progression-free survival (PFS) time was 11 months and the median overall survival (OS) time was 23 months. The 5-year PFS and OS rates were 22% and 25%, respectively. On the multivariate analyses, less than 4 involved lymph nodes was predictive of a better PFS and OS.

Conclusion

HDC with CTCb for MBC has acceptable toxicity; however, this treatment does not show a survival benefit.

Cancer Res Treat. 2004;36(3):192-198.   Published online June 30, 2004
DOI: https://doi.org/10.4143/crt.2004.36.3.192
AbstractAbstract PDFPubReaderePub
Purpose

To determine whether COX-2 expression is associated with clinicopathological parameters, including c-erb-B2 overexpression and angiogenesis, and the disease-free survival of patients with operable breast cancer.

Materials and Methods

Paraffin-embedded tissue samples were selected from 205 patients surgically resected for breast cancer, between 1991 and 1997, and followed-up for at least 4 years. Samples were immunohistochemically stained with antibodies to COX-2, c-erb-B2 and CD34.

Results

COX-2 and c-erb-B2 expressions were detected in 118/205 (57.6%) and 58/205 (28.3%) patients, respectively. COX-2 expression was significantly higher in c-erb-B2 positive than c-erb-B2 negative tumors (75.9% vs. 49.7%, p-value 0.001). COX-2 expression was positively correlated with microvessel count (13.3±8.0 vs. 6.6±7.0, p-value 0.050), but not with other clinicopathological characteristics, including tumor size, involved axil lary lymph nodes and estrogen or progesterone receptor status. Although COX-2 expression itself was not a prognostic marker, breast cancer patients with tumors that co-expressed both COX-2 and c-erb-B2 had a poorer 5-year disease-free survival rate than those that did not (60.2% vs. 78.3%, p-value 0.0527).

Conclusion

Our data suggest that COX-2 expression occurs frequently in c-erb-B2 positive breast cancer, and co-expression of COX-2 and c-erb-B2 may be a useful prognostic marker in patients with operable breast cancer.

AbstractAbstract PDF
Purpose
Although HER2 positivity is prevalent in microinvasive breast cancer (MIBC), data focused on HER2-positive MIBC are limited. We investigated the clinical course and long-term outcomes of HER2-positive MIBC and evaluated the role of adjuvant chemotherapy.
Materials and Methods
The study included patients with curatively resected pT1mi pN0 HER2-positive breast cancer between January 2000 and January 2020. Treatments and survival outcomes, including invasive breast cancer-free survival (IBCFS), distant recurrence-free survival (DRFS), and overall survival (OS) were analyzed.
Results
The analysis included 799 female patients. The median age was 51 years (range, 23–79), and 51.6% (n=412) were premenopausal. Multifocality was confirmed in 17.3% (n=138), and estrogen receptor (ER) positivity in 29.8% (n = 238). Adjuvant chemotherapy was administered to 17.5% (n=140), with doxifluridine in 96.4% of cases. One patient (0.1%) received trastuzumab. With a median follow-up of 119.0 months (95% CI, 114.0–127.0), the 8-year IBCFS, DRFS, and OS were 91.2% (95% CI, 89.1–93.3), 97.5% (95% CI, 96.4–98.7), and 98.8% (95% CI, 98.0–99.6), respectively. No significant differences were observed between patients with and without adjuvant chemotherapy. The lack of differences in IBCFS by chemotherapy was consistent across subgroups, including pre-/postmenopausal patients, grade 1-2/3 tumors, and ER-negative disease.
Conclusion
A clinically meaningful proportion of HER2-positive MIBC patients experience IBCFS events with long-term follow-up. Adjuvant chemotherapy did not improve survival, potentially due to the use of an outdated, ineffective regimen. The role of modern adjuvant regimens, particularly those incorporating HER2-targeted therapy, warrants further exploration.
