Objective: To examine the application of volume replacement techniques in breast conserving surgery for breast cancer. Methods: The clinic data of 76 breast cancer patients underwent a breast conserving surgery with volume replacement techniques at the Breast Center, Beijing Tongren Hospital, from June 2019 to June 2021 were analyzed retrospectively. All patients were female, aged (42.6±6.4) years (range: 32 to 56 years). Tumor staging inlcuded stage ⅡA in 36 cases, stage ⅡB in 24 cases, stage ⅢA in 12 cases, stage ⅢB in 4 cases. Three types of techniques included the lateral thoracic adipofascial flaps in 47 cases, the upper abdominal wall adipofascial flaps in 22 cases and the latissimus dorsi myocutaneous flap in 7 cases. The specimen volume of tumor expansion resection in breast conserving surgery was measured, while the operative time used for volume replacement techniques, postoperative drainage retention time, postoperative complications and patients' satisfaction with the breast shape were recorded. Results: The specimen volume of tumor was (100.9±24.2) ml (range: 55 to 157 ml) in lateral thoracic adipofascial flap group, (88.4±14.5) ml (67 to 118 ml) in upper abdominal wall adipofascial flap group, (179.7±22.9) ml (range: 155 to 220 ml) in latissimus dorsi myocutaneous flap group. The operative time used to restore the breast shape of the three groups were (52.9±9.0) minutes (range: 45 to 70 minutes), (63.2±8.8) minutes (range: 50 to 70 minutes) and (99.3±3.4) minutes (range: 95 to 105 minutes), respectively. The postoperative drainage retention times of the three groups were (8.6±1.2) days (range: 7 to 10 days), (9.4±0.9) days (range: 8 to 10 days) and (11.4±1.3) days (range: 10 to 13 days), respectively. All the 76 patients were evaluated for their satisfaction with the cosmetic outcomes, 64 patients (84.2%) were strongly satisfied and 12 patients (15.8%) were generally satisfied. The postoperative complications included fat liquefaction in 6 cases (2 cases in the lateral thoracic adipofascial flap group and 4 cases in the upper abdominal adipofascial flap group) and seroma in 4 cases (each 2 cases in the lateral thoracic adipofascial flap group and the latissimus dorsi myocutaneous flap group). Conclusions: For patients with large tissue loss during breast conserving surgery, the corresponding volume replacement techniques, including lateral thoracic adipofascial flaps, upper abdominal wall adpofascial flaps and latissimus dorsi myocutaneous flaps, should be reasonably selected for repair according to the tumor site and the size of the intraoperative breast loss, which can ensure the original volume and shape of the breast, with controllable postoperative complications.

INTRODUCTION: Oncoplastic breast-conserving surgery (OBCS) can cause breast asymmetry. Although contralateral breast surgery to achieve symmetry was offered to these patients, the uptake of symmetrisation was variable. We aimed to determine the factors that deter patients with breast cancer undergoing OBCS from opting for symmetrisation. METHODS: All patients with breast cancer who underwent OBCS of displacement type with no symmetrisation were prospectively surveyed to explore the social, economic, psychological and physical reasons against symmetrisation. RESULTS: A total of 28 patients participated in a survey administered at a mean 21.6 (range 2-47) months after OBCS. A combination of factors, such as worry and desire to treat breast cancer first (67.9%), not being overly concerned about breast cosmesis (57.1%) and fear of pain from additional operation (28.6%), deterred patients from immediate symmetrisation. Worry and desire to treat breast cancer first was the most important single factor for 50% of the patients. Reasons for no delayed symmetrisation included not being overly concerned about breast cosmesis (70.4%), fear of breast cancer recurrence (48.1%) and being happy with current breast cosmesis (33.3%), with the former two reasons equally cited as the single most important deterrent by 30% of patients each. CONCLUSION A combination of factors may deter patients from symmetrisation. The most significant factors deterring OBCS among patients were worry and desire to treat breast cancer first for immediate symmetrisation, and not being overly concerned about breast cosmesis and fear of breast cancer recurrence for delayed symmetrisation. Reassuring these patients may increase their uptake of symmetrisation, thereby improving patient cosmesis and satisfaction.

To study an automatic plan(AP) method for radiotherapy after breast-conserving surgery based on TiGRT system and and compare with manual plan (MP). The dosimetry parameters of 10 patients and the evaluation of scoring table were analyzed, it was found that the targets dose of AP were better than that of MP, but there was no statistical difference except for CI, The V5, V20 and V30 of affected lungs and whole lungs in AP were lower than all that in MP, the Dmean of hearts was slightly higher than that of MP, but the difference was not statistically significant, the MU of AP was increase by 16.1% compared with MP, the score of AP evaluation was increase by 6.1% compared with MP. So the AP could be programmed and automated while ensuring the quality of the plan, and can be used to design the plans for radiotherapy after breast-conserving surgery.

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. TRIAL REGISTRATION chictr.org.cn, ChiCTR1900026841; http://www.chictr.org.cn/showproj.aspx?proj=42783.

PURPOSE: We evaluated the clinical value of breast magnetic resonance imaging (MRI) in patients who underwent breast-conserving surgery (BCS). The degree of correlation between pathology size and MRI or ultrasonography (US) size was compared based on breast cancer subtypes. In addition, we investigated the positive margin rates. METHODS: Patients with invasive breast cancer who underwent preoperative breast MRI and US between 2011 and 2016 were included in the study. Lin's concordance correlation coefficient was used to measure the correlation between MRI or US andpathologic tumor extent. Tumor extent was defined as pathologic tumor size, including in situ carcinoma. Margin positivity was assessed based on frozen-section examination. RESULTS: A total of 516 patients with a single tumor who underwent BCS were included in the study. The correlation between pathologic size and MRI was significantly higher than that of US (r = 0.6975 vs. 0.6211, p = 0.001). The superiority of MRI over US in measuring the pathologic extent was only observed in triple-negative breast cancer (TNBC; r = 0.8089 vs. 0.6014, p < 0.001). The agreement between MRI or US and tumor extent was low for the human epidermal growth factor receptor 2 (HER2)-positive subtype (MRI: 0.5243, US: 0.4898). Moreover, the positive margin rate was higher in the HER2-positive subtype than in the others (luminal/HER2-negative: 11.6%, HER2-positive: 23.2%, TNBC: 17.8%, p = 0.019). The post hoc analysis showed that the HER2-positive subtype was more likely to show positive margins than the luminal/HER2-negative subtype (p = 0.007). CONCLUSION: Breast MRI was superior to US in the preoperative assessment of the pathologic extent of tumor size; this was most evident in TNBC. For HER2-positive tumors, imaging-pathologic discordance resulted in higher positive margin rates than that with other subtypes.

PURPOSE: Neoadjuvant chemotherapy (NAC) is less effective for luminal breast cancer because luminal breast cancer has a lower rate of pathological complete response (pCR) after NAC than human epidermal growth factor receptor 2 (HER2)-type and triple-negative breast cancer (TNBC). We investigated the efficacy of NAC and the predictive factors of a better response in luminal breast cancer. METHODS: Between 2010 and 2016, we retrieved data of 244 patients with clinically node-positive breast cancer who were treated with NAC followed by surgery from a prospectively collected database. We classified breast cancer into luminal HER2⁻ and non-luminal HER2⁻ breast cancer (luminal HER2⁺, HER2⁺, and TNBC types). We analyzed each subtype with respect to surgical outcomes, response to NAC, and determined variables associated with surgical outcomes and response in patients with luminal HER2⁻ breast cancer. RESULTS: The total, breast, and axillary pCR rates were significantly lower in 114 patients with luminal HER2⁻ breast cancer than in those with other subtypes (7.9%, 12.3%, and 22.8%, respectively). However, breast-conserving surgery (BCS) conversion and tumor response rates did not significantly differ between patients with luminal HER2⁻ and those with non-luminal HER2⁻ breast cancer (p = 0.836 and p = 0.180, respectively). In the multivariate analysis, high tumor response rate (≥ 46.4%) was significantly associated with an increased BCS conversion rate. In the subgroup analysis of luminal HER2⁻ breast cancer, the multivariate analysis showed that higher Ki67 expression and axilla pCR and BCS conversion rates were significantly associated with tumor response to NAC. CONCLUSION: Despite the low pCR rate, the tumor response and BCS conversion rates after NAC of luminal HER2⁻ breast cancer were similar to those of other subtypes. NAC has the potential benefit of reducing the size of breast cancer, thereby increasing the BCS conversion rate in luminal HER2⁻ breast cancer.

PURPOSE: Although surgery is the most frequently implemented treatment modality for breast cancer, many older patients with breast cancer are under- or untreated because of their high incidence of postoperative complications. We assessed the efficacy and safety of breast surgery under procedural sedation in older patients (aged >70 years) by comparing selected clinical and oncologic factors after surgery for breast cancer under general anesthesia versus procedural sedation. METHODS: Of 79 older patients with breast cancer, 49 underwent breast-conserving surgery, 30 under general anesthesia and 19 under procedural sedation, and relevant clinical and oncologic variables were compared and analyzed between groups. RESULTS: The mean age was younger in the general anesthesia group and the mean operation time, hospital stay, and fasting time shorter in the procedural sedation group. There were no statistically significant differences in oncologic results between the two groups during follow-up. CONCLUSION: Breast surgery under procedural sedation is a safe and effective means of reducing tumor burden in older patients with breast cancer when their American Society of Anesthesiologists (ASA) physical status indicates a high risk of life-threatening perioperative complications associated with general anesthesia. And we also found that the oncologic results may be not inferior to same procedure under general anesthesia.
