ABSTRACT
Background: Axillary lymph node status is one of the most important prognostic factors for breast cancer. Sentinel lymph node biopsy (SLNB) after mastectomy is highly controversial. There is not enough data about SLNB in the early period after nipple?sparing mastectomy (NSM). This study investigated the feasibility of SLNB in the early postoperative period of NSM. Materials and Methods: Patients who were operated on for breast cancer in Acibadem Maslak Hospital between 2009 and 2018 were searched retrospectively. Results of SLNB as the second session in patients whose final pathology report revealed breast carcinoma after contralateral/bilateral prophylactic mastectomy and mastectomy for benign lesions were evaluated. Results: In the early period (median 14 days) after NSM, SLNB was performed by intradermal radioisotope injection in five patients with occult breast cancer in contralateral/bilateral prophylactic mastectomy and in one patient with preoperatively suspicious mass which yielded breast cancer at final pathology. In five (80%) patients, SLNB was performed, whereas in one patient axillary lymph node dissection (ALND) was performed due to the undetectability of SLN. In one patient, micrometastasis was observed, whereas no metastasis was observed in other patients including the one who underwent ALND. No complication due to SLNB was detected. No recurrence and distant metastasis were detected in a mean follow?up of 42.82 (19�) months. While SLNB did not change the treatment of patients with contralateral occult carcinoma, other patients had hormonal therapy due to negative SLNB. Conclusion: SLNB in the early postoperative period of NSM can be performed by intradermal radioisotope injection. However, further studies are needed to determine the feasibility of SLNB in the early postoperative period of NSM
ABSTRACT
Objective:To explore the preventive value of "integrated prevention strategy" for nipple and areola ischemia after single-port endoscopic subcutaneous mastectomy.Methods:The clinical data of 72 patients with breast cancer who received single-port endoscopic subcutaneous mastectomy in Beijing Friendship Hospital, Capital Medical University from July 2019 to July 2021 were retrospectively analyzed, they were all female. The follow-up period was up to July 2022. According to the perioperative treatment methods, the patients were divided into observation group ( n=40) and control group ( n=32). The patients in the observation group who adopted the "integrated prevention strategy" scheme, and patients in the control group who adopted the conventional treatment scheme. The incidence of postoperative nipple and areola ischemic was compared between the two groups, and the postoperative cosmetic effect, quality of life and satisfaction of patients were evaluated. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups; the Chi-square test was used to compare the data groups. Results:The postoperative drainage volume in the observation group was significantly lower than that in the control group [(632.40±226.37) mL vs (774.91±239.85) mL], and the difference was statistically significant ( P=0.013). Two weeks after operation, there was 1 case of nipple and areola ischemia in the observation group, and 7 cases in the control group, the difference was statistically significant between the two groups ( P=0.019). Twelve months after operation, the score of breast satisfaction (83.93±11.64 vs 67.28±11.52), chest satisfaction (89.63±8.06 vs 83.03±9.49) and psychosocial well-being (89.43±12.42 vs 78.88±10.40) in the observation group were better than those in the control group, the differences were statistically significant ( P<0.05). Conclusion:"Integrated prevention strategy" can effectively prevent the occurrence of nipple and areola ischemic after single-port endoscopic subcutaneous mastectomy and improve patient satisfaction, which has certain promotion value.
ABSTRACT
Abstract Objective Nipple-sparing mastectomy (NSM) has been traditionally used in selected cases with tumor-to-nipple distance > 2 cm and negative frozen section of the base of the nipple. Recommending NSM in unselected populations remains controversial. The present study evaluated the oncological outcomes of patients submitted to NSM in an unselected population seen at a single center. Methods This retrospective cohort study included unselected patients with invasive carcinoma or ductal carcinoma in situ (DCIS) who underwent NSM in 2010 to 2020. The endpoints were locoregional recurrence, disease-free survival (DFS), and overall survival (OS), irrespective of tumor size or tumor-to-nipple distance. Results Seventy-six patients (mean age 46.1 years) (58 invasive carcinomas/18 DCIS) were included. The most invasive carcinomas were hormone-positive (60%) (HER2 overexpression: 24%; triple-negative: 16%), while 39% of DCIS were high-grade. Invasive carcinomas were T2 in 66% of cases, with axillary metastases in 38%. Surgical margins were all negative. All patients with invasive carcinoma received systemic treatment and 38% underwent radiotherapy. After a mean of 34.8 months, 3 patients with invasive carcinoma (5.1%) and 1 with DCIS (5.5%) had local recurrence. Two patients had distant metastasis and died during follow-up. The 5-year OS and DFS rates for invasive carcinoma were 98% and 83%, respectively. Conclusion In unselected cases, the 5-year oncological outcomes following NSM were found to be acceptable and comparable to previous reports. Further studies are required.
Resumo Objetivo A mastectomia poupadora do complexo areolo-mamilar (MPM) tem sido tradicionalmente utilizada em casos selecionados com distância tumor-mamilo > 2 cm e biópsia de congelação da base do mamilo negativa. Recomendar MPM em populações não selecionadas continua controverso. Este estudo avaliou os resultados oncológicos de pacientes submetidas à MPM em uma população não selecionada atendida em um único centro. Métodos Coorte retrospectivo incluindo pacientes não selecionadas com carcinoma invasivo ou carcinoma ductal in situ (CDIS) submetidas à MPM entre 2010 e 2020. Os desfechos incluíram: recorrência locorregional, sobrevida livre de doença (SLD) e sobrevida global (SG), independentemente do tamanho do tumor ou da distância tumor-mamilo. Resultados Setenta e seis pacientes (média: 46,1 anos de idade) (58 carcinomas invasivos/18 CDIS) foram incluídas. A maioria dos carcinomas invasivos era hormônio-positivo (60%) (superexpressão de HER2: 24%; triplo-negativo: 16%), enquanto 39% dos CDIS eram de alto grau histológico. Os carcinomas invasivos foram T2 em 66% dos casos, com metástases axilares em 38%. As margens cirúrgicas foram todas negativas. Todas as pacientes com carcinoma invasivo receberam tratamento sistêmico e 38% receberam radioterapia. Após um período médio de 34,8 meses, 3 pacientes com carcinoma invasivo (5,1%) e 1 com CDIS (5,5%) apresentaram recidiva local. Durante o acompanhamento, duas pacientes tiveram metástase à distância e vieram a óbito. As taxas de SG e SLD aos 5 anos para carcinoma invasivo foram de 98% e 83%, respectivamente. Conclusão Em casos não selecionados, os resultados oncológicos de 5 anos após MPM foram considerados aceitáveis e comparáveis a resultados anteriores. Estudos adicionais são necessários.

Abstract Objective: Breast surgery is considered a clean surgery; however, the rates of infection range between 3 and 15%. The objective of the present study was to intraoperatively investigate the presence of autochthonous microbiota in the breast. Methods: Pieces of breast tissue collected from 49 patients who underwent elective breast surgery (reconstructive, diagnostic, or oncologic) were cultured. The pieces of breast tissue were approximately 1 cm in diameter and were removed from the retroareolar area, medial quadrant, and lateral quadrant. Each piece of tissue was incubated in brain heart infusion (BHI) broth for 7 days at 37°C, and in cases in which the medium became turbid due to microorganism growth, the samples were placed in Petri dishes for culturing and isolating strains and for identifying species using an automated counter. Results: Microorganism growth was observed in the samples of 10 of the 49 patients (20.4%) and in 11 of the 218 pieces of tissue (5%). The detected species were Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis, and Aeromonas salmonicida. No patient with positive samples had clinical infection postoperatively. Conclusion: The presence of these bacteria in breast tissue in approximately 20% of the patients in this series suggests that breast surgery should be considered a potential source of contamination that may have implications for adverse reactions to breast implants and should be studied in the near future for their oncological implications in breast implant-associated large-cell lymphoma etiology.
Resumo Objetivo: A cirurgia de mama é considerada uma cirurgia limpa; entretanto, as taxas de infecção variam entre 3 e 15%. O objetivo deste estudo foi investigar no intraoperatório a presença de microbiota autóctone na mama. Métodos: Pedaços de tecido mamário coletados de 49 pacientes submetidas à cirurgia eletiva da mama (reconstrutiva, diagnóstica ou oncológica) foram cultivados. Os pedaços de tecido mamário tinham aproximadamente 1 cm de diâmetro e foram removidos da área retroareolar e dos quadrantes medial e lateral. Cada pedaço de tecido foi incubado em caldo BHI (brain heart infusion) por 7 dias a 37 ° C, e nos casos em que o meio ficou turvo devido ao crescimento de microrganismos, as amostras foram colocadas em placas de Petri para cultivo e isolamento de cepas e para identificação de espécies usando um contador automatizado. Resultados: O crescimento do microrganismo foi observado nas amostras de 10 das 49 pacientes (20,4%) e em 11 dos 218 pedaços de tecido (5%). As espécies detectadas foram Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis e Aeromonas salmonicida. Nenhum paciente com amostras positivas apresentou infecção clínica no pós-operatório. Conclusão: A presença dessas bactérias no tecido mamário em aproximadamente 20% das pacientes desta série sugere que a cirurgia mamária deve ser considerada uma fonte potencial de contaminação que pode ter implicações nas reações adversas aos implantes mamários e deve ser estudada em um futuro próximo por suas implicações oncológicas na etiologia do linfoma de células grandes associado ao implante de mama.

Objective:To explore the individualized surgical methods for elderly breast cancer patients.Methods:Elderly patients(aged≥70 years)with stage 0-Ⅲ breast cancer admitted to Beijing Tongren Hospital Affiliated to Capital Medical University from January 2013 to June 2020 were retrospectively analyzed.They were divided into three groups based on surgical methods: breast-conserving surgery, nipple-areola complex-sparing mastectomy and traditional mastectomy.Age, tumor size, lymph node involvement, hormone receptor status, anesthesia mode, surgical operation mode and patient prognosis were retrospectively analyzed.Results:A total of 144 patients(147 cases)were followed up for 8-96(36.5±10.7)months, with a median of 27 months.The overall survival rate was 88.9%, with breast cancer-related deaths at 6.3%, non-breast cancer-related deaths at 4.9%, local recurrence at 3.5%, and systemic metastasis at 5.6%.Among the three groups, 38.5%, 82.0% and 73.3%, respectively, received general anesthesia.Breast-conserving surgery showed the shortest operation time[(71.7±31.6)min vs.(84.8±24.8)min vs.(100.0±34.4)min, F=7.264, P=0.001], the lowest postoperative drainage volume[(39.5±75.4)ml vs.(154.92±135.6)ml vs.(334.1±287.2)ml, F=31.481, P<0.001]and the shortest drainage duration[(2.8±3.3)d vs.(6.3±2.8)d vs.(8.5±3.7)d, F=38.101, P<0.001]. Conclusions:The surgical treatment of elderly patients with breast cancer should be based on comprehensive evaluation and accurate molecular typing.Breast-conserving surgery is the preferred surgical method for elderly patients with hormone receptor-positive and cN0 breast cancer.Mastectomy with skin and nipple areola preservation where appropriate can improve the therapeutic effect and quality of life for elderly breast cancer patients.
ABSTRACT
OBJECTIVE: To analyze the clinical results of autologous reconstruction with DIEP flap following nipplesparing mastectomy and summarize experience.METHODS: From January 2016 to October 2018,DIEP flaps were utilized in 81 surgical cases of immediate breast reconstruction after mastectomy in Huashan Hospital of Fudan University.Success rate,safety,complications and patient satisfaction of nipple-sparing mastectomy(NSM) group(38 cases) and non-NSM(NNSM) group(43 cases) were compared.RESULTS: All DIEP flaps in 81 cases were successful with a flap survival rate of 100%.No skin necrosis,infection,or seroma occurred.There were 1 case(2.6%) of vascular complication and 2 cases(5.3%)of partial fat necrosis in NSM group,and 2 cases(4.7%) of vascular complication and 2 cases(4.7%) of partial fat necrosis in non-NSM group.No statistically significant difference was found between groups.Three cases of partial NAC ischemia(7.9%) happened in NSM group with no complete necrosis.There was a greater satisfaction in NSM group(81.6%) than non-NSM group(72.1%) on the overall impression of breast reconstruction in 6 months after surgeries,but the difference was not significant(P=0.315).Over a median follow-up period of 22 months,no local recurrence or distant metastasis were observed.CONCLUSION: Autologous reconstruction with DIEP flap following nipple-sparing mastectomy is safe and reliable for carefully selected patients when operations are executed with proficient operative skills.Complications are similar in the approach compared with DIEP flap immediate breast reconstruction following non-NSM.The technique has a controllable rate of NAC necrosis and offers the advantage of cosmetic effect.
ABSTRACT
This was a hospital based descriptive study. One hundred and ninety one therapeutic mastectomy specimens were included .Age range of patients was from twenty two to eighty seven years. Twenty specimens out of one hundred and ninety one cases had grossly retracted nipples with thirteen cases (65%) showing neoplastic involvement. Nine out of the remaining one hundred and seventy one grossly unremarkable nipples (5.26%) showed occult neoplastic involvement. Overall neoplastic involvement of nipple was 11.51% (22 out of 191). Location of tumour, nipple tumour distance and lymphovascular invasion showed significant association with nipple involvement. This study indicated a low frequency of neoplastic involvement of nipple in mastectomy specimens thus favouring replacement of conventional mastectomy with nipple sparing mastectomy in selected cases. This study also proposes a unique selection criteria for nipple sparing mastectomy
ABSTRACT
As a kind of breast cancer surgery choice,the nipple-sparing mastectomy (NSM)saves the patients′nipple-areola complex (NAC)which has significant meaning for patients′cosmetic results and posto-peration reconstruction.However,the clinical application of NSMis still in controversial.Some hot topics about oncological safety of NSM have appeared in recent years,such as the screening criterion of the enrolled patients,the situation of NAC involvement and the complications after NSM and handing methods.
