ABSTRACT
@#Objective To compare the differences of clinical effects between the bilateral endoscopic breast reconstruction and the open breast reconstruction. Methods The clinical data of 28 female patients who underwent bilateral breast graft reconstruction in the Department of Breast Surgery of West China Hospital from January 2017 to January 2021 were analyzed retrospectively. The patients were divided into two groups: an endoscopic group (n=12, aged 41.3±8.9 years) and an open group (n=16, aged 41.6±8.8 years). The clinical data of the two groups of patients were compared. Results There was no significant difference in demographic and oncological data between the two groups (P>0.05). There was a significant difference in the implants between the two groups (P=0.008). The operation time (298.2±108.6 min vs. 326.5±95.8 min, P=0.480) and anesthesia time (373.4±91.2 min vs. 400.3±97.1 min, P=0.463) were not significantly different. The total complications (P=0.035) and major complications (P=0.024) in the open group were more than those in the endoscopic group. For the comparison of breast satisfaction, psychosocial well-being and sexual well-being, the scores at six months and one year after surgery were higher in the endoscopic group than those in the open group (P<0.05). Conclusion The endoscopic reconstruction is safe and effective, with high satisfaction rates regarding breast reconstruction and quality of life, and is superior to conventional open surgery.
ABSTRACT
@#Objective To explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. Methods The 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. Results Endoscopic 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. Conclusion Endoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
ABSTRACT
@#The traditional view is that breast reconstruction is not an option for day surgery center. As a result, few hospitals in the world conduct this operation in day surgery center. Endoscopic breast reconstruction with liposuction and robot-assisted breast reconstruction are minimally invasive surgeries for breast cancer patients, but they cannot be carried out in the day surgery center due to long operation time. The novel endoscopic-assisted immediate implant-based breast reconstruction after nipple sparing mastectomy through a single axillary incision for breast cancer patients has been successfully conducted in the day surgery center in our hospital due to short operation time and small trauma. Standardized management of the complete process from the patient selection to follow-up after discharge brings rapid recovery and few complications. At the same time, the development of endoscopic surgery makes the breast almost scarless and improves aesthetic results. Therefore, the mode of endoscopic-assisted reconstruction in the day surgery center of our hospital is expected to be popularized in the whole country.
ABSTRACT
@#Objective To explore the surgical technique and preliminary results of endoscopic nipple-sparing mastectomy (E-NSM) and immediate pre-pectoral implant-based breast reconstruction (BR) with titanium-coated polypropylene mesh (TiLoop Bra) via single axillary incision for breast cancer patients. Methods The clinical data of 9 consecutive female patients who underwent E-NSM and immediate pre-pectoral implant-based BR with TiLoop Bra from March to May 2021 were retrospectively analyzed. The mean age of patients was 40.6 (22-60) years. The operation time, early complications were collected, and the patients' social and mental health, breast satisfaction and chest function before and after the operation were assessed with the BREAST-Q questionnaire. Results All the patients had unicentric tumor with a mean diameter of 2.4 (0.6-4.7) cm. The mean distance from the tumor to the nipple was 2.5 (2-4) cm. There were 2 patients with tumor stage 0 and 7 patients with stageⅠ. The mean operation time was 161.1 (125-201) min, the mean blood loss was 41.1 mL and the hospital stay time was 1.5 d. There were 5 patients in the day-care unit. All the patients were successfully followed up with a median follow-up time of 1 (1-2) month. One (11.1%) patient with depigmentation of the nipple-areola complex caused by mild ischemia. None of the patients had incision complications, subcutaneous emphysema, hematoma, infection, nipple-areola or skin flaps necrosis, implant loss. During the follow-up period, no local/regional recurrence or distant metastasis was found. Chest well-being was decreased in the first month after the surgery compared with preoperative status, and the difference was statistically significant (P=0.001). There was no statistical difference in the breast satisfaction or psychosocial function scores between pre- and post-operation (P>0.05). Conclusion E-NSM and immediate pre-pectoral implant-based BR with TiLoop Bra via single axillary incision has minimal trauma, rapid postoperative recovery, short operation time, few early complications and good early cosmetic effect, and the short-term result is satisfactory.
ABSTRACT
Objective@#The aim of this study was to investigate the association of the CYP19A1 rs7176005 single nucleotide polymorphism (SNP) with breast cancer risk and with clinicopathologic features of tumors.@*Methods@#This study was conducted by including 138 patients with breast cancer (cancer group), those who diagnosed as primary breast cancer after operation by pathology. There were 293 cases in the group of benign breast disease which was presented as a solid mass by the color ultrasound and pathologically diagnosed as "fibroadenoma or adenosis" (benign breast disease group), the cases were paired with breast cancer patients by age±5 in the same period, and there were 259 cases in the group of healthy control who received routine physical examination during the same period and were paired with breast cancer patients by age±5 without any detection of breast related diseases (healthy control group) at West China hospital between September 2012 and November 2016. The CYP19A1 rs7176005 SNP was detected by a direct sequencing method. Hardy-Weinberg test was used to analyze the genetic balance of the 3 groups. Chi square test was used to compare the distribution of rs7176005 genotypes between the 3 groups, and the differences of clinicopathological features in breast cancer patients carrying different genotypes.@*Results@#The ages of the breast cancer cases, the benign breast disease group and the healthy control group were (44.69±8.09), (42.33±11.44) and (41.92±9.61) years old, respectively. Hardy-Weinberg equilibrium test identified that the composition ratios of alleles C and T in breast cancer group, benign breast disease group and healthy group were not statistically significant (χ2 values were 0.83, 0.34 and 0.04, respectively, P values were 0.363, 0.561, and 0.852, respectively). All the three groups met the genetic balance, had consistency and could represent the population. Among the 138 cases of breast cancer, the CYP19A1 rs7176005 SNP was significantly associated with the diameter of the tumor (P=0.031). The majority of tumor size was <2 cm in patients who carrying TT and CT genotypes, and the proportion was 75% (12/16) and 58% (40/69), respectively. While those patients with TT genotype were mainly >2 cm and ≤5 cm, and the proportion was 51% (27/53). The distribution of TNM stage among patients with different genotypes was also statistically significant (χ2=11.19, P=0.025). The most common stage was Ⅱ in Patients who carrying CC and CT genotypes, and the proportion was 45.3% (24/53) and 52.2% (36/69), respectively. While those patients with TT genotype was mainly in stage Ⅰ and the proportion was 56.3% (9/16).@*Conclusion@#Though the CYP19A1 rs7176005 SNP is not associated with breast cancer development, breast cancer patients with the C allele exhibit a high tumor growth rate and large diameters.
