[PMID: 37916188 PMCID: PMC10616842 DOI: 10.3389/fmolb.2023.1248410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 10/02/2023] [Indexed: 11/03/2023] Open
Abstract
Background: Breast cancer patients with synchronous ipsilateral supraclavicular lymph node metastases (ISLNM) have unfavorable prognoses. The role of supraclavicular lymph node dissection (SLND) as a surgical intervention in the treatment of this condition remains controversial. In this study, we aimed to evaluate the prognostic factors associated with breast cancer with ISLNM and to assess the potential impact of aggressive locoregional surgical management on patient outcomes. Methods: We conducted a retrospective analysis of 250 breast cancer patients with ISLNM who were treated with curative intent at our institution between 2000 and 2020. The cohort was stratified into groups based on the extent of axillary surgery. The first group, comprising 185 patients, underwent level I/II axillary dissection. The second group, consisting of 65 patients, underwent aggressive locoregional surgery, including levels I/II/III (infraclavicular) dissection in 37 patients and levels I/II/III + SLND in 28 patients. Our study evaluated overall survival (OS) and disease-free survival (DFS) as primary endpoints, and locoregional recurrence-free survival (LRRFS) and distant metastasis-free survival (DMFS) as secondary endpoints. Results: The median follow-up time among all patients was 5.92 years (1.05-15.36 years). The 5-year OS rate was 71.89%, while the DFS rate, LRRFS rate, and DMFS rates were 59.25%, 66.38%, and 64.98%, respectively. A significant difference in OS, DFS, LRRFS, and DMFS was observed between the second group and the first group (p < 0.01). No beneficial impact on recurrence, metastasis, or survival outcomes was observed in the levels I/II/III + SLND group compared to the levels I/II/III dissection group. Multivariate logistic regression analysis revealed that levels I/II/III ± SLND surgery and T stage were associated with OS (p = 0.006 and p = 0.026), while levels I/II/III ± SLND surgery, ER+/HER2-, and histologic grade were associated with DFS (p = 0.032, p = 0.001, p = 0.032). Conclusion: Breast cancer with ISLNM may be considered a locoregional disease, requiring a combination of systemic and local therapies. Aggressive locoregional surgery has been shown to positively impact recurrence, metastasis, and survival outcomes. This approach may provide improved management of the ISLNM for breast cancer patients.

Jiao Y, Guo X, Wu H, Lv Q. Surgery on Metastatic Foci is a Better Strategy for Stage IV Breast Cancer Patients with only Nonregional Lymph Node Metastasis. Adv Ther 2023; 40:3247-3262. [PMID: 37270436 DOI: 10.1007/s12325-023-02557-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 05/16/2023] [Indexed: 06/05/2023]
Abstract
INTRODUCTION Our study aims to explore whether breast cancer patients with non-regional lymph node (NRLN) metastasis benefit from surgery on distant nodes, and to determine the influencing factors affecting the prognosis of this type of patient. METHODS Information of invasive ductal carcinoma (IDC) patients from 2004 to 2016 was extracted from the Surveillance, Epidemiology, and End Results (SEER) database and analyzed by statistical methods, including multivariate Cox regression model, chi-squared test, propensity score matching (PSM), Kaplan-Meier plot, and log-rank test. RESULTS A total of 4236 M1 patients met the designated criteria. Among 847 patients with only NRLN metastasis who have detailed information, only 114 patients received surgery on metastatic distant lymph nodes. The Kaplan-Meier plot for overall survival (OS) showed that the prognosis of NRLN metastatic patients was superior to visceral metastasis (P < 0.0001) but similar to supraclavicular metastasis (P = 0.33). In addition, NRLN metastatic patients who underwent surgery on the NRLNs were found to have superior prognoses in terms of both OS (P = 0.041) and cancer-specific survival (P = 0.034) compared with those who did not undergo NRLN surgery. We have also demonstrated that NRLN metastatic patients who have received radiotherapy plus chemotherapy for primary tumors gain superior survival compared with those who only received chemotherapy apart from NRLN surgery. CONCLUSION Surgery on NRLN and radiotherapy for the primary tumor improved the prognosis of NRLN metastatic patients. Thus, the classification of NRLN, especially contralateral axillary lymph node metastasis (CAM), into the M1 breast cancer stage should be reconsidered. Different locoregional treatment strategies for metastatic foci should be recommended for patients with only NRLN and patients with visceral metastasis.

Long-Term Outcomes of Breast Cancer Patients Who Underwent Selective Neck Dissection for Metachronous Isolated Supraclavicular Nodal Metastasis. Cancers (Basel) 2021; 14:cancers14010164. [PMID: 35008328 PMCID: PMC8750885 DOI: 10.3390/cancers14010164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 12/24/2021] [Accepted: 12/27/2021] [Indexed: 11/16/2022] Open
Abstract
We retrospectively enrolled 139 patients who developed metachronous isolated supraclavicular lymph node metastasis (miSLNM) from 8129 consecutive patients who underwent primary surgery between 1990 and 2008 at a single medical center. The median age was 47 years. The median follow-up time from date of primary tumor surgery was 73.1 months, and the median time to the date of neck relapse was 43.9 months in this study. Sixty-one (43.9%) patients underwent selective neck dissection (SND). The 5-year distant metastasis-free survival (DMFS), post-recurrence survival, and overall survival (OS) rates in the SND group were 31.1%, 40.3%, and 68.9%, respectively, whereas those of the no-SND group were 9.7%, 32.9%, and 57.7%, respectively (p = 0.001). No SND and time interval from primary tumor surgery to neck relapse ≤24 months were the only significant risk factors in the multivariate analysis of DMFS (hazard ratio (HR), 1.77; 95% confidence interval (CI), 1.23-2.56; p = 0.002 and HR, 1.76, 95% CI, 1.23-2.52; p = 0.002, respectively) and OS (HR, 1.77; 95% CI, 1.22-2.55; p = 0.003 and HR, 3.54, 95% CI, 2.44-5.16; p < 0.0001, respectively). Multimodal therapy, including neck dissection, significantly improved the DMFS and OS of miSLNM. Survival improvement after miSLNM control by intensive surgical treatment suggests that miSLNM is not distant metastasis.
