Objective： To explore the therapeutic effect and associated techniques of breast-conserving therapy on patients with clinical stage Ⅰ and stage Ⅱ breast cancer. Methods： 216 female patients with breast cancer underwent breast-conserving therapy from December 1993 to October 2004. Their data were analyzed retrospectively. The breast-conserving therapy consisted of lumpectomy or quadrant removal of the breast, postoperative radiotherapy, chemotherapy and endocrine therapy. Of them, 209 patients underwent axillary lymph node dissection. Results： There were no operative complications. 216 patients were followed-up 3 to 147 months, the medial follow-up time was 78 months. The local recurrence rate was 1.85%. Two patients died and one of them was not related with breast cancer. Presence or absence of fibrosis, shape of breast, asymmetry, pigmentation and handle were taken into consideration for cosmetic evaluation by the patients and experienced breast surgeon. Breasts were scored cosmetically as excellent and good in 199 patients, the rate of satisfactory was 92.13%. Conclusion： Breast-conserving therapy for early breast cancer is e safe end effective therapy. It has less trauma end less complications and can also raise the quality of life in the patients. But we must obey the strict indications and reasonable techniques.

Clinical significance of S100A7 protein in predicting recurrence of breast cancer in patients undergoing breast-conserving surgery with radiotherapy

Objective To investigate the relationship between the expression of S100A7 protein and prediction of recurrence and prognosis of breast cancer in patients undergoing breast-conserving surgery combined with radiotherapy.Methods 349 samples of carcinoma tissue wax blocks were selected from January 2011 to January 2014 in Qingdao Central Hospital.All the patients had undergone breast-conserving surgery.We analyzed S100A7 expression in tumor tissue by immunohistochemical staining.Using univariate and multivariate analyses,we evaluated the relationship between S100A7 and clinical results,to explore independent risk factors for local regional recurrence(LRR).Results The positive expression of S100A7 in the recurrence group(66.7%)was significantly higher than in the non-recurrence group(38.4%),P=0.025.A log-rank test showed that high S100A7 expression was significantly correlated with 5-year regional recurrence free survival rate(RFS)(94.9%vs 89.5%,P=0.0408),distant metastasis free survival rate(DFS)(95.4%vs 83.5%,P<0.001),and overall survival rate(OS)(99.0%vs 92.5%,P=0.0011).Histological grade,vessel carcinoma embolus,lymph node metastasis,S100A7 expression,and tumor size were factors that influenced RFS.Multivariate analysis of the Cox proportional hazard model showed that high S100A7 expression was an independent risk factor that affected breast cancer RFS(HR=6.864,95%CI:1.575-29.915,P=0.01).Thus,we concluded that high S100A7 expression is associated with increased risk of LRR and distant metastasis of breast cancer after breast-conserving surgery and postoperative radiotherapy.S100A7 can be used as a molecular marker to screen for patients with high recurrence risk after breast-conserving surgery.

Application of Ultimate Oncoplastic Surgery in Breast-Conserving Surgery

Objective To investigate the application of oncoplastic surgery in breast-conserving surgery.Methods We retrospectively analyzed the clinical data of 103 breast cancer patients who underwent breast-conserving surgery in the First Affiliated Hospital of Henan University.All the patients were female whose tumor volume-to-breast volume ratio was greater than 20%.Fifty-two patients were treated with oncoplastic breast-conversing surgery(observation group),and 51 patients were treated with traditional breast-conserving surgery(control group).The volume of resected tissue,subjective satisfaction with breast shape,objective score of breast shape,and follow-up were compared between the two groups.Results In the observation group,the weight of resected breast tissue was 64.2–172.1 g,with a median of 98.7 g.In the control group,the weight of resected breast tissue was 67.5–175.7 g,with a median of 102.3 g.After 12 months of follow-up,the subjective satisfaction rate and objective score of breast shape in the observation group were significantly better than those in the traditional breast-conserving surgery group(P<0.05).There was no recurrence,metastasis,or death in the two groups.There was no significant difference in postoperative complications between the two groups(P>0.05).Conclusion Oncoplastic breast-conserving surgery leads to better cosmetic results and a more satisfactory clinical results.

Whole breast ultrafractionation radiotherapy after breast-conserving surgery in early breast cancer: A single-center, prospective, observational study from China

Objective:This single-center,prospective,observational study was designed to investigate the toxicities,patient-reported outcome(PRO),and dosimetric analysis of whole breast ultrafractionation radiotherapy(RT)after breast-conserving surgery(BCS)in early breast cancer(BC).Patients and methods:Patients diagnosed with BC stage I,II and treated with BCS were enrolled.A dose of 26 Gray(Gy)in five fractions was prescribed to the whole breast and tumor bed.Clinical endpoints included toxicities,PRO,and dosimetric analysis.PRO was measured by the European Organization for Research and Treatment of Cancer general quality of life questionnaire(EORTC QLQ-C30)and the BC-specific questionnaire(EORTC QLQ-BR23)questionnaires.Results:Between January 2022 and June 2023,62 female patients were enrolled.The median age was 45 years.Most patients(83.9%)were diagnosed with pathological stage I disease.The median planning target volume(PTV)was 456.4 mL.The minimum,maximum,and mean doses,and D95(dose of PTV irradiated volume more than 95%)to PTV were 20.2,28.8,27.2,and 26.3 Gy,respectively.The median mean lung dose and percentage lung volume receiving 8 Gy(V8)were 3.6 Gy and 13.4%,respectively.The median mean heart dose,V1.5(percentage of organ volume irradiated with 1.5 Gy or higher),and V7(percentage of organ volume irradiated with 7 Gy or higher)were 0.6 Gy,6.8%,and 0.4%,respectively.Cosmetic effects before RT showed no obvious differences compared to that post RT.No toxicities of grade 3 or higher occurred.Five patients had asymptomatic radiation pneumonia(grade 1),and 12 patients had radiation dermatitis(grade 1).No factor was significantly related to radiation dermatitis or radiation pneumonia.For the EORTC QLQ-C30 and QLQ-BR23 questionnaires,all function and symptom scores before RT had no significant differences compared with that after RT,1−2 months after RT,and 3−4 months after RT.Ultrafractionation RT did not worsen PRO.The 1-year crude local control was 100%.Conclusion:Whole breast ultrafractionation RT after BCS in early BC has no severe toxicities and does not affect PRO.These results need to be further validated with a longer follow-up and a larger sample size.

Application of Deep Inspiration Breath Hold Technique in Radiotherapy After Breast- Conserving Surgery for Left Breast Cancer and Its Improvement on Cardiac Dose

Objective:To analyze the application of deep inspiration breath hold technique in radiotherapy after breast-conserving surgery for left breast cancer and the improvement of cardiac dose.Methods:A total of 45 patients with left breast cancer treated in our hospital after breast-conserving surgery were selected,and the selection time was set from January 2020 to August 2022.All patients received radiotherapy.The right breast,heart,and lung volumes,and dose parameters of the heart,lungs,right breast,and left anterior descending coronary artery were compared under free breathing(FB)and deep inspiration breath hold(DIBH)technical modes.Results:The heart volume of the DIBH group was smaller than that of the FB group,and the left and right lung volumes were significantly larger than those of the FB group.In the DIBH group,the heart dose parameters V5,proper lung dose parameters,and left anterior descending coronary artery dose parameters were found lower than that of the FB group,and the differences were statistically significant(P<0.05).Conclusion:Compared with FB,the DIBH technique can reduce the heart’s size and increase the lung volume when used for radiotherapy after breast-conserving surgery for left breast cancer.It also reduces the dose to the heart,right lung,and left anterior descending coronary artery,thus protecting the heart and lungs.

Imaging of the treated breast post breast conservation surgery/oncoplasty: Pictorial review

Mammographic appearance of the normal breast is altered in the post-operative setting. It is essential to be aware of the normal findings as well as to identify features of recurrent disease with particular emphasis on radiologicalpathological concordance. Digital breast tomosynthesis and volumetric breast density add incremental value in this clinical setting. We present a pictorial review of various cases to illustrate normal post-operative findings as well as mammographic features suspicious for recurrent disease.

Advances in Oncoplastic Breast Surgery

Evidence from six prospective,randomized trials has shown that breast-conserving surgery(BCS)is a safe alternative to mastectomy,and this led to a heightened interest in achieving and balancing local control and cosmetic outcome post-surgery.However,it is also becoming apparent that conventional BCS techniques may not produce cosmetically favorable results for patients who present with ill-defined or poorly situated breast tumors.Other factors that are commonly found in Chinese women,such as small-volume and denser breasts,also contribute to the difficulty in achieving an optimal cosmetic outcome post-surgery,thus necessitating the need for oncoplastic breast surgery techniques to be employed.This article serves as an overview of the recent advances and principles of oncoplastic breast surgery,as well as the use of autologous fat grafts to improve cosmetic results and eliminate remaining smaller deformities post-surgery.

Oncoplastic Breast Surgery Using Spindle Shaped-Partial Mastectomy for Early Breast Cancer in the Upper Quadrant Area

Background: Oncoplastic surgery is becoming more common, however, only several reports have been published in Japan. We report the results of simple oncoplastic surgery for Japanese patients with early breast cancer in the upper quadrant area. Methods: In seven patients with a past history of breast-feeding and ptotic breasts, we performed oncoplastic surgery involving partial mastectomy and the resection of excess skin and parenchymal tissue. Results: None of the patients received a contralateral operation to produce symmetrical breasts. The width of the resected excess skin tissue ranged from 20 to 50 mm, with the mean width being 30 mm, and its length ranged from 50 to 90, with the mean length being 77 mm. The width of the resected gland tissue ranged from 40 to 65 mm, with the mean width being 53 mm, and its length ranged from 70 to 100 mm, with the mean length being 97 mm. The cosmetic results were excellent. Conclusions: Oncoplastic surgery using spindle shaped-resection was successfully performed in patients with upper quadrant lesions, and the cosmetic results were excellent.

Breast Conserving Surgery: Has the Standard of Care Enhanced Outcomes for Patients?

Breast Conserving Surgery (BCS) is a rapidly emerging field increasingly adopted to facilitate breast conservation and preserve breast aesthetics. Since the publication of the Randomized Controlled Trials (RCTs) of Breast Conserving Surgery versus mastectomy in early breast cancer, the adoption of BCS for breast cancer patients’ surgical management has been comprehensive. A computerized bibliographic search was performed on PubMed/MEDLINE, Embase, Google Scholar and Cochrane library databases. This article aims to perform a thorough review of new data regarding invasive cancer and margins while evaluating patient outcomes related to BCS after neoadjuvant chemotherapy focusing on margins, imaging evaluation, the extent of resection, and local regional recurrence outcomes. The growth pattern and biopsy of Ductal Carcinoma In Situ (DCIS) differ from invasive cancer, impacting margins. It is essential to understand how the Society of Surgical Oncology (SSO) DCIS margin guideline has influenced practice. Early breast cancer surgical management should be unique to each patient, driven by evidence-based medicine, and focused on specific clinical, histological, and molecular characteristics of the tumor. Conclusion: The current management for early breast cancer should be tailored and evidence-based to each patient based on the clinical, histological and molecular characteristics of the tumor. Presumably, the standard of care in BCS has enhanced the outcomes for this patient population. This review made by peers will help surgeons to stay up to date with the current literature and help them manage breast cancer while improving multiple clinical parameters such as Disease-Free Survival (DFS), Recurrence-Free Survival (RFS) and most importantly Overall Survival (OS).

Comparison of breast-conserving surgery and mastectomy in early breast cancer using observational data revisited:a propensity score-matched analysis

Recent observational studies showed that breast-conserving surgery(BCS) resulted in superior survival compared to mastectomy in breast cancer patients. This study compared the clinical outcomes of BCS and mastectomy using propensity score(PS)matching analysis, which had advantages over conventional methods in reducing bias. Nonmetastatic breast cancer patients who underwent BCS and mastectomy were matched 1:1 based on their PS. We used the Kaplan-Meier method and Cox-regression model to estimate the treatment effects. A total of 2,866 patients with a median follow-up time of 67 months were included in the original study population. Although the mastectomy cohort(N=1,219) had more advanced disease compared to the BCS cohort(N=1,647), LRFS was similar between the two groups(93.8% vs. 92.4%, P>0.05). BCS(vs. mastectomy) was associated with improved DFS(73.8% vs. 58.7%, P<0.01) and CSS(91% vs. 78.2%, P<0.01) in the original population. In the PS-matched population(N=1,668), clinicopathological features were equally distributed between the two cohorts. BCS(vs. mastectomy) was not associated with improved DFS(70.7% vs. 66.9%, P>0.05) or CSS(87.5% vs. 84.9%, P>0.05). We found that PS methods reduce bias when estimating treatment effects using observational data. BCS and mastectomy show equivalent outcomes in nonmetastatic breast cancer patients.

A multi-center investigation of breast-conserving surgery based on data from the Chinese Society of Breast Surgery(CSBrS-005)

Background:Although breast-conserving surgery is one of the standard treatments for breast cancer,few studies have assessed its recent implementation in China.We aimed to clarify the current real-world status of breast-conserving surgery in China.Methods:This cross-sectional survey relied on data collected by the Chinese Society of Breast Surgery(CSBrS)to examine patients who underwent this surgery between January 2018 and December 2018.The survey was conducted using a uniform electronic questionnaire to collect information,including clinical and pathological data on these patients.Results:Overall,4459 breast-conserving surgeries were performed in 34 member units of CSBrS,accounting for 14.6%of all breast cancer surgeries performed in these units during the study period.In patients who underwent breast-conserving surgery with information on tumor size available,more than half(61.2%)of the tumors were smaller than 2 cm in diameter,and only 87(3.2%)tumors were larger than 4 cm in diameter.Among patients who underwent breast-conserving surgeries,457(10.2%)patients received neoadjuvant therapy before the surgery.Among patients with a reported margin width,34(2.0%)patients had a margin of≤2 mm,and 1530(88.2%)of them had a margin of>5 mm.Conclusions:This study demonstrated the rates of breast-conserving surgery in member units of the CSBrS,and introduced the characteristics and surgical margins of patients who underwent this surgery.This information helps describe the real-world status of breast-conserving surgery in China.

Multicenter prospective study of magnetic resonance imaging prior to breast-conserving surgery for breast cancer

Background This multicenter prospective study aimed to assess the utility of dynamic enhanced magnetic resonance imaging （MRI） prior to breast-conserving surgery for breast cancer.Methods The research subjects were drawn from patients with primary early resectable breast cancer treated in the breast disease centers of six three-level hospitals in Beijing from 1 January 2010 to 31 December 2012.The participants were allocated to a breast-conserving surgery group （breast-conserving group） or a total mastectomy group （total mastectomy group）.Enhanced MRI was used to measure breast volume,longest diameter of tumor and tumor volume.The correlations between these measurements and those derived from histopathologic findings were assessed.The relationships between the success rate of breast-conserving surgery and MRI-and pathology-based measurement results were statistically analyzed in the breast-conserving group.Results The study included 461 cases in the total mastectomy group and 195 in the breast-conserving group.Allocation to these groups was based on clinical indications and patient preferences.The cut-off for concurrence between MRI-and pathology-based measurements of the longest diameter of tumor was set at 0.3 cm.In the total mastectomy group,the confidence interval for 95％ concurrence of these measurements was 35.41％-44.63％.Correlation coefficients for MRI and histopathology-based measurements of breast volume,tumor volume and tumor volume/breast volume ratio were r=0.861,0.569,and 0.600,respectively （all P ＜0.001）.In the breast-conserving group,with 0.30 cm taken as the cut-off for concurrence,the 95％ confidence interval for MRI and pathology-based measurements of the longest diameter of tumor was 29.98％-44.01％.The subjective and objective success rates for breast-conserving surgery were 100％ and 88.54％,respectively.Conclusions There were significant correlations between dynamic enhanced MRI-and histopathology-based measurements of the longest diameter of breast lesions,breast and tumor volumes,and breast volume/tumor volume ratios.Preoperative MRI examination improves the success rate of breast-conserving surgery.

Diagnostic value of preoperative examination for evaluating margin status in breast cancer

BACKGROUND A positive resection margin is a major risk factor for local breast cancer recurrence after breast-conserving surgery(BCS).Preoperative imaging examinations are frequently employed to assess the surgical margin.AIM To investigate the role and value of preoperative imaging examinations[magnetic resonance imaging(MRI),molybdenum target,and ultrasound]in evaluating margins for BCS.METHODS A retrospective study was conducted on 323 breast cancer patients who met the criteria for BCS and consented to the procedure from January 2014 to July 2021.The study gathered preoperative imaging data(MRI,ultrasound,and molybdenum target examination)and intraoperative and postoperative pathological information.Based on their BCS outcomes,patients were categorized into positive and negative margin groups.Subsequently,the patients were randomly split into a training set(226 patients,approximately 70%)and a validation set(97 patients,approximately 30%).The imaging and pathological information was analyzed and summarized using R software.Non-conditional logistic regression and LASSO regression were conducted in the validation set to identify factors that might influence the failure of BCS.A column chart was generated and applied to the validation set to examine the relationship between pathological margin range and prognosis.This study aims to identify the risk factors associated with failure in BCS.RESULTS The multivariate non-conditional logistic regression analysis demonstrated that various factors raise the risk of positive margins following BCS.These factors comprise non-mass enhancement(NME)on dynamic contrastenhanced MRI,multiple focal vascular signs around the lesion on MRI,tumor size exceeding 2 cm,type III timesignal intensity curve,indistinct margins on molybdenum target examination,unclear margins on ultrasound examination,and estrogen receptor(ER)positivity in immunohistochemistry.LASSO regression was additionally employed in this study to identify four predictive factors for the model:ER,molybdenum target tumor type(MT Xmd Shape),maximum intensity projection imaging feature,and lesion type on MRI.The model constructed with these predictive factors exhibited strong consistency with the real-world scenario in both the training set and validation set.Particularly,the outcomes of the column chart model accurately predicted the likelihood of positive margins in BCS.CONCLUSION The proposed column chart model effectively predicts the success of BCS for breast cancer.The model utilizes preoperative ultrasound,molybdenum target,MRI,and core needle biopsy pathology evaluation results,all of which align with the real-world scenario.Hence,our model can offer dependable guidance for clinical decisionmaking concerning BCS.

Surgical Outcomes Following Partial Breast Reconstruction with Chest Wall Perforator Flaps

Introduction: In the last two decades, chest wall perforator flaps (CWPF) have become a versatile tissue replacement technique for partial breast reconstruction following breast-conserving surgery (BCS) in well-selected cases. We present the surgical outcome of 81 patients with chest wall perforator flaps used for breast-conserving surgery. Methods: We recorded the outcomes of three oncoplastic breast surgeons who performed partial breast reconstruction with chest wall perforator flaps from 1st January 2018 to 30th June 2022 at Sherwood Forest Hospitals NHS Foundation Trust. Data were collected on patient demographics, including age, BMI, smoking status, bra size, previous treatments, type of CWPF procedure, tumor size (measured clinically, via imaging and histologically), biopsy results, specimen weight, margins involvement, re-operation rate, surgical site infection (SSI), flap loss, flap shrinkage, hematoma, and seroma rates. Results: A total of 81 patients were included in this study, with an average age of 55.7 years and a body mass index (BMI) of 26.7 kg/m2. The bra size varied between A to FF with A (7.4%), B (28.3%), C (38.2%), D (13.6%), DD (11.1%), and FF (1.2%). 14.8% of the patients had neoadjuvant chemotherapy (NACT). For 45 patients, LICAP (lateral intercostal artery perforator), 16 AICAP (anterior intercostal artery perforator), 13 MICAP (medial intercostal artery perforator), and for seven patients, LTAP (lateral thoracic artery perforator) flaps were used. The average tumor was measured at 15.75 mm clinically, 19.1 mm via imaging, and 19.6 mm histologically. Biopsy showed that 16% of the tumors were ductal carcinoma in situ (DCIS), and 84% were invasive. 16% of patients had involved margins, and re-excision was required in 10 patients, and completion mastectomy was performed in 2 patients. A thirty-day SSI rate was 6.2%, with flap-related complications, including flap loss and shrinkage, at 3.7% and 4.9%, respectively. In addition, 3.7% had a hematoma, and 17.3% had other complications. Conclusion: Partial breast reconstruction with perforator flaps is an excellent volume replacement technique in breast-conserving surgery with acceptable complications in well-selected cases.

乳腺癌新辅助化疗后局部病灶的外科处理原则

新辅助化疗是局部晚期乳腺癌标准治疗方案中的重要组成部分之一，可提高肿瘤切除率与保乳率。对于早期乳腺癌，新辅助化疗可使原发肿瘤降期以提高局部切除的可行性，并可早期评价化疗敏感性从而指导个体化治疗。一些研究已经证实新辅助化疗的反应与患者生存率相关，许多患者将得益于其对远处器官内微小转移灶的控制。本文将就新辅助化疗后保乳的选择、乳房再造术的时机以及区域淋巴结治疗等局部病灶外科处理的研究进展作一综述。1）新辅助化疗后的保乳手术不应为追求保乳而以降低生存率或增加局部复发为代价，且选择标准应与直接手术相一致，存在局部晚期病变但对化疗反应好的患者也考虑保乳手术。2）新辅助化疗后的晚期乳腺癌患者行即刻乳房再造术，其并发症发生率并无增加；但放疗可导致假体再造乳房的包膜挛缩或反复感染，对自体乳房再造的影响尚无定论，因此局部晚期乳腺癌患者应考虑行延迟乳房再造术；Kronowitz等人提出的“延迟一即刻”乳房再造是一种具有实用价值的方法。3）对新辅助化疗敏感的患者可考虑通过前哨淋巴结活检进行腋窝淋巴结分期；在新辅助化疗前后行活检各有利弊，一些研究中将超声和前哨淋巴结活检相结合来判断腋窝淋巴结状态的方法值得借鉴，但尚需更多的研究加以证实。

隐匿性乳腺癌的诊治探讨

目的探讨隐匿性乳腺癌的临床特点及诊治方法。方法对9例隐匿性乳腺癌患者的临床资料及疗效进行回顾性分析。结果术后9例患者中6例找到乳腺癌原发灶（3~8 mm）,随访1~8年,7例行乳腺癌改良根治术的患者中5例未出现局部复发或远处转移,1例术后1年发现骨转移灶,另1例术后1.5年死于脑、肺及骨转移;2例行保乳术的患者均无局部复发或远处转移。结论对有腋窝淋巴结转移腺癌而无明显原发癌灶的女性患者,应高度警惕隐匿性乳腺癌。治疗宜采用保乳术联合腋窝淋巴结清扫术,辅以全乳腺及区域淋巴结引流区放疗、化疗、内分泌治疗以及可能的靶向治疗。
