Purpose: Surgical site infections (SSIs) remain a concern after implant-based breast reconstruction, despite preventive measures. These infections can have serious consequences. This study evaluated the correlation between drain tip culture results and SSIs in this patient population.
Methods: We analyzed data from patients who underwent implant-based breast reconstruction between July 2021 and May 2023. Drain tip cultures were collected, and any SSIs occurring within one month of surgery were documented. We then compared clinical data with the culture results.
Results: A total of 263 drain tip cultures were included. Notably, none of the 61 patients who underwent tissue expander removal and implant insertion had positive cultures. However, among the 202 patients who received tissue expanders or direct-to-implant procedures, 11 (5.45%) had positive cultures, with a total of 12 SSIs identified. Importantly, five of the 11 culture-positive wounds developed SSIs. Multivariate analysis revealed a significant two-way association between infection and positive drain tip cultures. For Staphylococcus aureus specifically, drain tip cultures showed excellent predictive value: sensitivity (33.33%), specificity (100%), positive predictive value (100%), and negative predictive value (95.96%).
Conclusion: Drain tip cultures from immediate implant-based breast reconstructions significantly correlated with SSIs. Close monitoring is crucial, especially when S. aureus is identified in the culture.

Purpose: The 21-gene recurrence score (RS) can guide adjuvant chemotherapy decisions in the multidisciplinary treatment (MDT) of patients with early breast cancer. This study aimed to evaluate the influence of the 21-gene RS assay on patient' compliance with MDT and its association with disease outcomes.
Methods: Patients diagnosed with pN0-1, hormone receptor-positive, human epidermal growth factor receptor-2-negative breast cancer between January 2013 and June 2019 were enrolled. A logistic regression model was used to identify parameters associated with treatment adherence. Prognostic indicators were evaluated using the Cox proportional hazard models.
Results: After the assay, patients were less likely to violate the treatment plan (14.9% vs. 23.1%, p < 0.001), and higher compliance rates were observed for chemotherapy (p = 0.042), radiotherapy (p = 0.012), and endocrine therapy (p < 0.001). Multivariable analysis demonstrated that the 21-gene RS assay (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.09-1.88; p = 0.009) was independently associated with MDT compliance. Moreover, compliance with MDT was independently associated with better disease-free survival (hazard ratio, 0.43; 95% CI, 0.29-0.64; p < 0.001), regardless of the 21-gene RS assay (interaction p = 0.842).
Conclusion: The 21-gene RS assay improved the MDT compliance rate in patients with early breast cancer. Adherence to MDT is associated with a better prognosis.

Purpose: During the major shift in China's policies on coronavirus disease 2019 (COVID-19), many residents will be infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) over a short period, including a few patients with breast cancer undergoing neoadjuvant chemotherapy (NAC). Moreover, it is unknown whether this comorbidity affects the efficacy of NAC for breast cancer and the patient's psychological state and quality of life (QOL). This study aims to answer these questions.
Methods: The clinical data of 2,793 patients with breast cancer who received NAC at The Affiliated Hospital of Qingdao University were retrospectively collected. The infected and non-infected groups were divided according to whether they were infected with COVID-19 during NAC. Propensity score matching was used to reduce patient selection bias. The effectiveness, psychological well-being, and QOL of the two groups were compared.
Results: No discernible differences were observed in the pathological complete response rates (p = 0.307) and major histological responses rate (p = 0.398) between the infected and non-infected groups. Following the full course of NAC, the Functional Assessment of Cancer Treatment General (p < 0.001) and Functional Assessment of Cancer Therapy for Breast Cancer (p < 0.001) were lower in the infected group than the non-infected group, the Hospital Anxiety and Depression Scale (HADS) anxiety scale (p < 0.001) and HADS depression scale (p < 0.001) were considerably higher in the infected group than the non-infected group.
Conclusion: With timely treatment and effective medical management, SARS-CoV-2 does not appear to affect the efficacy of NAC; however, it can significantly affect the QOL of patients and increase their psychological distress. Therefore, in addition to a timely assessment of the efficacy of NAC, it is necessary to dynamically understand the patient's psychological state and QOL.

Purpose: Oncotype DX (ODX) predicts the risk of recurrence and benefits of adding chemotherapy for patients with estrogen receptor positive (ER+)/human epidermal growth factor receptor 2 negative (HER2-) early-stage breast cancer. We aimed to develop a simplified scoring system using readily available clinicopathological parameters to predict a high-risk ODX recurrence score (RS) while minimizing reproducibility issues regarding Ki-67 index evaluation methods.
Methods: We enrolled 300 patients with ER+/HER2- early breast cancer, for whom ODX RS data were available in the test set. Using the QuPath image analysis platform, we systematically evaluated the average, hotspot, and hottest spot Ki-67 scores in the test set. Logistic regression analyses were conducted to establish a predictive scoring system for high-risk ODX RS. An independent validation set comprising 117 patients over different periods was established.
Results: Factors such as age ≤ 50 years, invasive ductal carcinoma tumor type, histologic grade 2 or 3, tumor necrosis, progesterone receptor negativity, and a high Roche-analyzed Ki-67 score (> 20) were associated with high-risk ODX RS. These variables were incorporated into our scoring system. The area under the curve of the scoring system was 0.8057. When applied to both the test and validation sets with a cutoff value of 3, the sensitivity of our scoring system was 92%.
Conclusion: We successfully developed a scoring system based on the systematic evaluation of Ki-67 scoring methods. We believe that our user-friendly predictive scoring system for high risk ODX RS could help clinicians in identifying patients who may or may require additional ODX testing.

Breast implant augmentation is a low-risk procedure with few life-threatening complications, most commonly rupture or leakage and contraction of the capsule. Breast implant-associated (BIA) malignancies are rare. Anaplastic large cell lymphoma (ALCL) is the most well-known neoplastic condition associated with breast augmentation. Carcinomas arising in association with implants have been reported but are rarer than ALCL. BIA-mesenchymal tumors are extremely rare and most are locally aggressive fibromatosis. To date, only eight cases of BIA sarcomas have been reported. Herein, we describe a case of silicone BIA-undifferentiated pleomorphic sarcoma (UPS) that was initially mistaken for ALCL because of a significant clinical and radiological overlap in presentation and imaging. Here, we present the morphological and molecular features of this rare neoplasm. We reviewed the existing literature related to BIA sarcomas to highlight the importance of considering this diagnosis in cases of recurrent ALCL-negative BIA effusions.

Purpose: Pencil-beam scanning (PBS) is a modern delivery technique used in proton beam therapy (PBT) to reduce normal tissue reactions. No dosimetric correlation between dermatitis and PBS has been reported for breast cancer. The current study aimed to investigate the factors associated with grade 2 or higher dermatitis in patients with breast cancer undergoing PBT using PBS.
Methods: The medical data of 42 patients with breast cancer who underwent adjuvant radiotherapy between December 2019 and September 2023 were reviewed. All patients received hypofractionated radiotherapy (HFRT), either 26 Gy (relative biological effectiveness [RBE])/five fractions or 40.05 or 43.5 Gy (RBE)/15 fractions, for the whole breast/chest wall with or without nodal irradiation. The duration of acute radiation dermatitis was defined as within 90 days from the start of radiotherapy. The Kaplan-Meier method and Cox proportional hazards model were used for univariate and multivariate analyses of the actuarial rates of grade 2-3 dermatitis.
Results: Twenty-two (52.4%) and 20 (47.6%) patients were diagnosed with grade 1 and 2 dermatitis, respectively. Multivariate analysis revealed a clinical target volume (CTV) ≥ of 320 cc (p = 0.035) and a skin dose of D10cc ≥ 38.3 Gy (RBE) (p = 0.009) as independent factors of grade 2 dermatitis. The 10-week cumulative grade 2 dermatitis rates were 88.2%, 39.4%, and 8.3% (p < 0.001) for patients with both high, either high, and neither high CTV and D10cc, respectively.
Conclusion: To the best of our knowledge, this is the first study on dosimetric correlations for dermatitis in patients with breast cancer who underwent hypofractionated PBT using PBS. In the era of HFRT, skin dose modulation using PBS may reduce the incidence of dermatitis.

The global incidence of breast cancer is on the rise, a trend also observed in South Korea. However, thanks to the rapid advancements in anticancer therapies, survival rates are improving. Consequently, post-treatment health and quality of life for breast cancer survivors are emerging as significant concerns, particularly regarding treatment-related cardiotoxicity. In this review, we delve into the cardiovascular complications associated with breast cancer treatment, explore surveillance protocols for early detection and diagnosis of late complications, and discuss protective strategies against cardiotoxicity in breast cancer patients undergoing anticancer therapy, drawing from multiple guidelines.

Purpose: The Avoid Axillary Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy (ASLAN) trial aims to demonstrate the oncologic safety of omitting axillary surgery in patients with excellent response after neoadjuvant chemotherapy (NACT) for early human epidermal growth factor 2 (HER2)-positive (+)/triple-negative breast cancer (TNBC) who have undergone breast-conserving surgery (BCS) and adjuvant radiotherapy. The ASLAN trial will provide crucial information that could change the procedure in highly selected patients undergoing axillary surgery after NACT.
Methods: ASLAN is a prospective, multicenter, and single-arm surgical trial. The recruitment will be conducted among five tertiary care hospitals in the Republic of Korea. The total number of patients to be recruited will be 178, and we plan to complete patient enrollment by December 2023. The enrollment is considered among patients with HER2+ breast cancer (BC) or TNBC at clinical stage T1-3N0-1M0 who are expected to achieve breast pathological complete response (BpCR) based on a combination of radiologic imaging and physical examination after NACT. BCS was performed on eligible patients. After BCS, patients who showed BpCR were enrolled with the omission of sentinel lymph node biopsy (SLNB). The primary study endpoint upon completion of this trial is 5-year recurrence-free survival, and the secondary endpoints include the 5-year ipsilateral breast tumor recurrence interval, 5-year ipsilateral axillary recurrence interval, 5-year distant metastasis-free survival, 5-year BC-specific survival, 5-year overall survival, 5-year contralateral BC-free survival, re-operation rate according to breast biopsy after NACT, adverse events within 5 years, and quality of life.
Discussion: Several clinical trials are currently underway to determine whether SLNB can be omitted after NACT in patients with HER2+ BC or TNBC that are expected to achieve pathologic complete response. The ASLAN trial is expected to provide valuable clues regarding the feasibility of omitting axillary surgery in highly selected patients.

Purpose: This study aimed to analyze the treatment outcomes and adverse effects of moderately hypofractionated partial breast irradiation (PBI) in patients with early breast cancer.
Methods: In total, 473 patients with early breast cancer or carcinoma in situ were diagnosed with Tis or T1N0 disease and underwent PBI following breast-conserving surgery. All histologic tumor types, close surgical margins within 1 mm of the tumor, and multifocal tumors were included in this study. A radiation dose of 50 Gy in 20 fractions was delivered over 4 weeks using intensity-modulated radiotherapy technique. Dosimetric data, recurrence patterns, survival outcomes, and adverse events were retrospectively analyzed.
Results: During a median follow-up of 28.9 months, seven patients (1.5%) experienced ipsilateral breast tumor recurrence (IBTR). Two patients had regional recurrence, four patients developed contralateral breast cancer, and no distant metastases were observed. The locoregional recurrence rate in the ipsilateral breast was 1.8%. Two deaths occurred during the follow-up period, but were not attributed to breast cancer. The 2-year disease-free survival and 2-year overall survival rates were was 94.0% and 99.8%, respectively. Acute adverse events occurred in 131 patients (27.1%), and were distributed among all grades, with only two patients (0.4%) experiencing grade 3 events. Late adverse events were noted in 16 patients (3.4%), and were distributed among all grades, including grade 3 events in four patients (0.8%). No grade 4 or 5 events were observed.
Conclusion: Hypofractionated PBI demonstrated favorable IBTR rates in patients with early breast cancer, with low incidence of acute and late toxicities in the short-term analysis.
