Objective To explore the clinical application of tissue flap in repairing the residual cavity formed by breast conserving surgery. Methods Retrospective analysis for clinical data of 120 early breast cancer patients who received breast conserving surgery in our hospital from January 2013 to December 2016 was performed. Among them, 60 cases (observation group) were implemented tissue flap repairing operation while the other 60 cases (control group) were operated by using the traditional surgery method. The clinical data of the two groups were compared analytically in four aspects: postoperative complications, postoperative breast beauty, subjective satisfaction of patients, and postoperative recurrence and metastasis. Results ① Postoperative complications: 3 cases of complications occurred in the control groupand 2 cases in the observation group, and there was no significant difference in the incidence of complications between the 2 groups (χ2=0.209, P=0.648). ② Postoperative breast beauty: in the control group, there were 23 excellent cases, 16 good cases, 12 common cases, and 9 poor cases; in the observation group, there were 51 excellent cases, 5 good cases, 3 common cases, and 1 poor cases. The difference of postoperative breast beauty between the 2 groups was statistically significant (Z=–5.234, P<0.001). ③ Subjective satisfaction of patients: in the control group, 28 cases very satisfied, 18 cases satisfied, 12 cases generally satisfied, and 2 cases dissatisfied; in the observation group, 40 cases satisfied, 18 cases very satisfied, and 2 cases generally satisfied. The subjective satisfaction of the patients in the observation group was better than that of the control group (Z=–4.381, P<0.001). ④ Postoperative follow-up: no recurrence and death occurred in both of 2 groups, but 2 cases occurred metastasis in the control group and 1 case in the observation group. The contrast difference in the incidence of metastasis was not statistically significant (χ2=0.342, P=0.559). Conclusion During breast conserving surgery, the use of surrounding tissue flap to repair residual cavity, compared with traditional breast conserving surgery without tissue flap repairment, does not increase postoperative complications, recurrence, and metastasis, and it has good cosmetic effect after breast surgery, as well as the patients’ subjective satisfaction is good.
Objective To explore the tumor shrinking pattern, the image evaluation methods of the residual lesions after neoadjuvant chemotherapy, and the indications, the resection range, the surgical margins, the management of sentinel lymph node biopsy (SLNB) and axillary lymph nodes of breast conserving surgery after neoadjuvant chemotherapy. Methods Domestic and foreign literatures about the breast conserving surgery after neoadjuvant chemotherapy were collected and reviwed. Results Breast conserving surgery after neoadjuvant chemotherapy raised the rate of breast conserving surgery and improved the postoperative life quality of patients, while the overall survival rate had no significant difference compared with mastectomy. Tumor shrinking pattern and its related factors after neoadjuvant chemotherapy remain required further study. At present, the indications for breast conserving surgery after neoadjuvant chemotherapy still mainly refered to that for early stage breast cancer. Resection range was more recognized to the scope of residual tumor lesions after chemotherapy. The margins were more widely accepted as which were without tumor involved. Although there were some controversies about the use of SLNB and the management of axillary lymph nodes based on the results of SLNB in breast conserving surgery after neoadjuvant chemotherapy, it was still considered necessary at the basis of the accurate biopsy technique acquired. Conclusions At present, breast conserving treatment after neoadjuvant chemotherapy is considered safe and effective. However, it is necessary to proceed cautiously under the conditions of adequate communication of local recurrence rate, standardized local treatment, standard postoperative radiotherapy, systemic adjuvant therapy, and regular follow-up.
ObjectiveTo investigate the prognosis after breast conserving surgery (BCS) and modified radical mastectomy (MRM) in patients with stage Ⅰ–Ⅱ breast cancer, and analyze the factors related to locoregional recurrence (LRR).MethodsThe clinicopathologic and prognostic data of patients with stage Ⅰ–Ⅱ breast cancer who underwent the surgical treatment in the First Affiliated Hospital of Chongqing Medical University from January 2011 to December 2014 were analyzed. The clinicopathologic characteristics and prognostic differences of the BCS group and MRM group were compared. The factors related to LRR of patients underwent the BCS and MRM were analyzed.ResultsA total of 1 330 patients with stage Ⅰ–Ⅱ breast cancer were included in this study, including 230 in the BCS group and 1 100 in the MRM group. Compared with the MRM group, the patients in the BCS group had higher height (P<0.001), younger age (P<0.001), smaller tumor diameter (P<0.001), and less axillary lymph node metastasis (P<0.001). Up to August 2019, 149 cases (18 cases in the BCS group and 131 cases in the MRM group) were lost, with a follow-up rate of 88.8%. The median follow-up time was 71 months (4－103 months). The LRR rate of the BCS group was higher than that of the MRM group (6.1% versus 2.5%, χ2=7.002, P<0.01). The locoregional recurrence-free survival of the MRM group was better than that of the BCS group (χ2=7.886, P<0.01). However, there were no statistical differences between the two groups in terms of the distant metastasis-free survival and disease-free survival (P>0.05). In the patients underwent the BCS, the HER-2 was associated with the LRR (P<0.05), and the axillary lymph node metastasis was associated with the LRR in the patients underwent the MRM (P<0.05).ConclusionsAccording to results of this study, although there is a significant difference in locoregional recurrence-free survival between BCS group and MRM group in patients with stage Ⅰ–Ⅱ breast cancer, there are no statistical differences in distant metastasis-free survival and disease-free survival between the two groups. Therefore, it is safe and feasible for choosing appropriate patients with stage Ⅰ–Ⅱ breast cancer to underwent breast-conserving treatment.
ObjectiveTo explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. MethodsThe clinical data of 18 patients received endoscopic breast tumor resection from September 2020 to December 2021 in the Department of Breast Surgery, West China Hospital, Sichuan University, were retrospectively analyzed to evaluate the feasibility, tumor safety and postoperative cosmetic effect. There were 7 patients with benign breast tumors (a benign breast tumor group) and 11 patients with early breast cancer (a malignant breast tumor group). Breast-Q and Scar-Q questionnaires were used to evaluate postoperative quality of life and satisfaction of patients. ResultsEndoscopic breast tumor resection was performed successfully in 18 female patients, among whom 12 patients received day surgery. The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. ConclusionEndoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
ObjectiveTo investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. MethodsThe demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from July 2021 to May 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed ResultsA total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts and chest condition between the two groups (P>0.05). ConclusionIt is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.
ObjectiveTo explore the clinical efficacy of volume displacement techniques for breast defects following breast conserving surgery. MethodsAfter inclusion and exclusion, the patients with breast defects following breast conserving surgery in the Minda Hospital of Hubei Minzu University from February 2013 to March 2020 were retrospectively enrolled, and were assigned into a volume displacement group and volume replacement group according to different surgical techniques. Then the outcomes were compared between the two groups, including short-term efficacy (incision length, operation time, intraoperative blood loss, volume of resected specimen, cosmetic effect, patients’ subjective satisfaction, total postoperative complications, and total hospitalization time) and long-term efficacy (local recurrence rate, 3-year tumor-free survival, and 3-year overall survival). ResultsA total of 208 eligible patients were included in this study, including 105 in the volume displacement group and 103 in the volume replacement group before propensity score matching (PSM); after PMS, a total of 62 patients were enrolled, including 33 in the volume displacement group and 29 in the volume replacement group. No statistical difference was reported in the baseline data between two groups (P>0.05), except that the maximum diameter of lesion in the volume displacement group was smaller than that in the volume replacement group (P<0.05). The incision length, operation time, total hospitalization time, total postoperative complication rate, local recurrence rate, 3-year tumor-free survival rate, and 3-year overall survival rate had no statistical differences between the two groups (P>0.05), whereas the intraoperative blood loss was less (t=3.294, P=0.002) and the volume of resected specimen was smaller (t=2.030, P=0.047) in the volume displacement group as compared with the volume replacement group, and the cosmetic effect and patients’ subjective satisfaction were better in the volume displacement group as compared with the volume replacement group (Z=2.297, P=0.022; Z=2.256, P=0.024). ConclusionThe study analysis with small size samples reveals that volume displacement technique for breast defects following breast conserving surgery can achieve a good cosmetic effect and high patients’ subjective satisfaction without increasing risk of postoperative complications and tumour recurrence, which demonstrates a good long-term efficacy profile.
ObjectiveTo compare the effectiveness of sequential method pure single-port lumpectomy-breast conserving surgery (SMPSL-BCS) in treating early-stage breast cancer patients with tumors in different quadrants. Methods A retrospective analysis was conducted on 200 early-stage breast cancer female patients admitted between January 2023 and December 2023. According to the quadrant where the tumor was located, the patients were allocated into the upper outer quadrant group (UO group), lower outer quadrant group (LO group), upper inner quadrant group (UI group), and lower inner quadrant group (LI group), with 50 cases in each group. There was no significant difference (P>0.05) in the baseline data, including age, body mass index, smoking history, marital status, comorbidities, affected breast side, maximum tumor diameter on ultrasound, maximum pathological tumor diameter, clinical tumor stage, molecular subtype, and disease duration. The operation time, intraoperative blood loss, postoperative drainage volume, and extubation time were recorded and compared between groups. Additionally, the occurrence of early-stage complications (1-3 months after operation; including subcutaneous fluid accumulation, incision infection, superficial skin burns) and late-stage complications (>3 months after operation; including pectoralis major muscle adhesion, changes in breast appearance and shape, sensory discomfort) were assessed. At 6 months after operation, the cosmetic outcome of breast-conserving surgery was rated for all groups. Results The UO group had the shortest operation time, followed by the UI group, LO group, and LI group, showing significant differences between groups (P<0.05). The UO group had the least intraoperative blood loss, followed by the LO group, UI group, and LI group; except for the difference between UO group and LO group, which was not significant (P>0.05), the differences between the other groups were significant (P<0.05). The UO group had the least postoperative drainage volume, followed by the LO group, UI group, and LI group; except for the difference between LO group and UI group, which was not significant (P>0.05), the differences between the other groups were significant (P<0.05). The extubation time of the LI group was significantly longer than that of the other groups (P<0.05). All patients were followed up 4-12 months, with an average of 8 months. And 193 patients were followed up more than 6 months, including 48 patients in UO group, 47 in LO group, 49 in UI group, and 49 in LI group. In the early-stage period, the LI group had a higher incidence of subcutaneous fluid accumulation after tube removal compared to the UO group and LO group (P<0.05), while there was no significant difference in the incidences of other early complications between groups (P>0.05). In the late-stage period, the LI group had significantly higher incidences of pectoralis major muscle adhesion and changes in breast appearance and shape than UO group and LO group (P<0.05), and a significantly higher incidence of sensory discomfort than UO group (P<0.05). There was no significant difference in the incidences of other late-stage complications between groups (P>0.05). At 6 months after operation, the cosmetic outcomes of breast-conserving surgery were significantly better in UO group, LO group, and UI group than in LI group (P<0.05); there was no significant difference between the other groups (P>0.05). Conclusion In the treatment of early-stage breast cancer using SMPSL-BCS, patients with tumors located in the upper outer quadrant show the best effectiveness. The effectivenesses are similar for patients with tumors in the lower outer and upper inner quadrants. However, patients with tumors in the lower inner quadrant do not experience significant advantages. Therefore, it is recommended that SMPSL-BCS should not be the first-choice surgical method for patients with tumors in the lower inner quadrant.
