Effect of magnesium sulfate with ketamine infusions on intraoperative and postoperative analgesia in cancer breast surgeries: a randomized double-blind trial

Abstract Background Opioids are the cornerstone in managing postoperative pain; however, they have many side effects. Ketamine and Magnesium (Mg) are NMDA receptor antagonists used as adjuvant analgesics to decrease postoperative opioid consumption. Objective We assumed that adding Mg to ketamine infusion can improve the intraoperative and postoperative analgesic efficacy of ketamine infusion alone in cancer breast surgeries. Methods Ninety patients aged between 18 and 65 years and undergoing elective cancer breast surgery were included in this prospective randomized, double-blind study. Group K received ketamine 0.5 mg.kg-1 bolus then 0.12 mg.kg-1.h-1 infusion for the first 24 hours postoperatively. Group KM: received ketamine 0.5 mg.kg-1 and Mg sulfate 50 mg.kg-1, then ketamine 0.12 mg.kg-1.h-1 and Mg sulfate 8 mg.kg-1.h-1 infusions for the first 24 hours postoperative. The primary outcome was the morphine consumption in the first 24 hours postoperative, while the secondary outcomes were: intraoperative fentanyl consumption, NRS, side effects, and chronic postoperative pain. Results Group KM had less postoperative opioid consumption (14.12 ± 5.11 mg) than Group K (19.43 ± 6.8 mg). Also, Group KM had less intraoperative fentanyl consumption. Both groups were similar in postoperative NRS scores, the incidence of side effects related to opioids, and chronic neuropathic pain. Conclusion Adding Mg to ketamine infusion can safely improve intraoperative and postoperative analgesia with opioid-sparing effect in cancer breast surgery.

Peritumoral infiltration of local anesthetic before surgery in early breast cancer: a comment

This is a comment on a study recently published about peritumoral infiltration of local anesthetic before surgery in early breast cancer. Previously, animal models and a randomized study for stage IV breast cancer patients inferred that the removal of the primary tumor resulted in increased growth factors and worse distant disease control. Therefore, breast cancer surgery might not be a strictly local intervention. In this new randomized study, the intervention was a peritumoral infiltration of local anesthetic ­ lidocaine 0.5% in the six tumor margins, as an attempt to limit the systemic repercussions of surgery. Although the adjuvant treatment available for the study seems outdated, leading us to question the external validation, limited resources may have increased the power of surgery. Unknown mechanisms during surgery can change the patient's journey, and it is our duty to look at surgical studies with due seriousness

Use of the serratus anterior fascia in immediate implant-based breast reconstruction

Using the serratus anterior fascia may be a safe and effective option to recreate the lateral breast profile during subpectoral breast reconstruction, with minimal functional impact on the donor site. However, the literature is scarce when it comes to studies on this fascia flap in implant-based reconstruction. This article aimed to review the use of the serratus anterior fascia in immediate implant-based breast reconstruction, searching the electronic databases PubMed, Embase, Lilacs, and SciELO. The search was carried out by combining the following keywords: 'breast reconstruction' and 'serratus anterior fascia'. In the Pubmed and Embase databases, the search yielded a total of 12 and 15 articles, respectively, of which seven were selected according to the scope of this article. We found no studies on serratus anterior fascia and breast reconstruction in the Lilacs and SciELO databases. All works have results favorable for the use of the serratus anterior fascia flap and agree that this technique can be considered in the algorithm for the coverage of the inferolateral portion during subpectoral breast reconstruction

Magnetic resonance differential analysis for different hormone receptor expression status in HER-2-positive breast cancer / 中南大学学报(医学版)

OBJECTIVES@#Currently, it is difficult to assess the expression status of hormone receptor (HR) in breast malignant tumors with human epidermal growth factor receptor 2 (HER-2)-positive in the early preoperative stage, and it is difficult to predict whether it is non-invasively. This study aims to explore the value of MRI on the different HR expression status (HR+/HR-) in HER-2 positive breast cancer.@*METHODS@#Thirty patients with HR+ HER-2-positive breast cancer (HR+ group) and 23 patients with HR-HER-2-positive breast cancer (HR- group) from the First Hospital of Hunan University of Traditional Chinese Medicine between January 7, 2015 and November 26, 2021 were selected as subjects, and all the patients were examined by MRI and all were confirmed by surgery or pathological biopsy puncture. The immunohistochemical staining results were used as the gold standard to analyze the basic clinical conditions, peri-lesion conditions and MRI sign characteristics in the 2 groups.@*RESULTS@#There were all significant differences in terms of mass margins, internal reinforcement features, and apparent diffusion coefficient (ADC) values between the HR+ group and the HR- group (all P<0.05). The logistic multivariate regression model showed that: when the lesion presented as a mass-type breast cancer on MRI, the internal enhancement features of the lesion were an independent predictor for differentiation in the 2 types of breast cancer [odds ratio (OR)=5.95, 95% CI: 1.223 to 28.951, P<0.05], and the mass margin (OR=0.386, 95% CI: 0.137 to 1.082, P>0.05) and ADC value (OR=0.234, 95% CI: 0.001 to 105.293, P>0.05) were not the independent predictors in distinguishing the 2 types of breast cancer.@*CONCLUSIONS@#Multiparametric MRI has good diagnostic value for HR expression status in HER-2-positive breast cancer. Combined logistic regression analysis to construct a predictive model may be helpful to the identical diagnosis.

Predicting survival and prognosis of postoperative breast cancer brain metastasis: a population-based retrospective analysis / 中华医学杂志(英文版)

BACKGROUND@#Breast cancer is one of the most common cancer in women and a proportion of patients experiences brain metastases with poor prognosis. The study aimed to construct a novel predictive clinical model to evaluate the overall survival (OS) of patients with postoperative brain metastasis of breast cancer (BCBM) and validate its effectiveness.@*METHODS@#From 2010 to 2020, a total of 310 female patients with BCBM were diagnosed in The Affiliated Cancer Hospital of Xinjiang Medical University, and they were randomly assigned to the training cohort and the validation cohort. Data of another 173 BCBM patients were collected from the Surveillance, Epidemiology, and End Results Program (SEER) database as an external validation cohort. In the training cohort, the least absolute shrinkage and selection operator (LASSO) Cox regression model was used to determine the fundamental clinical predictive indicators and the nomogram was constructed to predict OS. The model capability was assessed using receiver operating characteristic, C-index, and calibration curves. Kaplan-Meier survival analysis was performed to evaluate clinical effectiveness of the risk stratification system in the model. The accuracy and prediction capability of the model were verified using the validation and SEER cohorts.@*RESULTS@#LASSO Cox regression analysis revealed that lymph node metastasis, molecular subtype, tumor size, chemotherapy, radiotherapy, and lung metastasis were statistically significantly correlated with BCBM. The C-indexes of the survival nomogram in the training, validation, and SEER cohorts were 0.714, 0.710, and 0.670, respectively, which showed good prediction capability. The calibration curves demonstrated that the nomogram had great forecast precision, and a dynamic diagram was drawn to increase the maneuverability of the results. The Risk Stratification System showed that the OS of low-risk patients was considerably better than that of high-risk patients ( P < 0.001).@*CONCLUSION@#The nomogram prediction model constructed in this study has a good predictive value, which can effectively evaluate the survival rate of patients with postoperative BCBM.

Application of volume replacement techniques in breast conserving surgery for breast cancer treatment / 中华外科杂志

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.

Effectiveness of lobulated pedicled rectus abdominis myocutaneous flap for repairing huge chest wall defect / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect.@*METHODS@#Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly.@*RESULTS@#All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis).@*CONCLUSION@#The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.

Erysipelas after surgery for breast cancer: a real-world cohort

Erysipelas is often related to lymphedema, which can occur in up to 60% of cases, with advanced age, radiotherapy, tumor extension, surgical approach, and infections as risk factors. The aim of this study was to present and discuss a series of cases of erysipelas after breast cancer surgery treated in a private mastology clinic over the past ten years. This is a retrospective horizontal cohort study in which we selected all cases of erysipelas after breast cancer surgery from 2009 to 2019. The following were evaluated: number of patients treated with a diagnosis of breast carcinoma with axillary approach, age, surgery performed, adjuvant treatment and treatment of erysipelas, presence of lymphedema, and measurement of circumferences between both arms and associated diseases. A total of 12 cases of breast cancer were treated. In 66.66% of cases, a radical axillary lymphadenectomy was performed, and in 16.66% of cases, only a sentinel lymph node investigation was performed. The average age was 67.6 years. Erysipelas appeared, on average, 43 months after cancer diagnosis. Two deaths were reported due to severe erysipelas leading to sepsis. More studies are still needed on the subject. Of the 12 cases in this study, eight (66.66%) were associated with lymphedema. Only two (16.66%) of the patients in this group who developed erysipelas were not submitted to axillary dissection. The treatment for 50% of the participants in this research was with penicillin G benzathine. There were three relapses, and two patients died during the research period

Efficacy of serratus anterior plane block versus thoracic paravertebral block for postoperative analgesia after breast cancer surgery - a randomized trial

Abstract Background Breast cancer surgery is associated with considerable acute post-surgical pain and restricted mobility. Various regional and neuraxial anesthesia techniques have been used to alleviate post-mastectomy pain. Ultrasound-guided serratus anterior plane block (SAPB) has been considered a simple and safe technique. This randomized control study was performed to compare the efficacy of SAPB with the thoracic paravertebral block (TPVB) for postoperative analgesia after breast cancer surgery. Methods A total of 40 adult ASA physical status I - II female patients undergoing radical mastectomy were randomly allocated into two groups to receive either ultrasound-guided TPVB or SAPB with 0.4 mL.kg-1 0.5% ropivacaine, 30 min before surgery. All patients received standardized general anesthesia for surgery. Injection diclofenac and tramadol were used for postoperative rescue analgesia. The time to first rescue analgesia, total analgesic consumption in the first 24 hours, postoperative pain scores, and any adverse effects were recorded. Results The time to first rescue analgesia was significantly longer in the SAPB group (255.3 ± 47.8 min) as compared with the TPVB group (146.8 ± 30.4 min) (p< 0.001). Total diclofenac consumption in 24 hours was also less in the SAPB group (138.8 ± 44.0 mg vs 210.0 ± 39.2 mg in SAPB and TPVB group respectively, p< 0.001). Postoperative pain scores were significantly lower in the SAPB group as compared with TPVB group (p< 0.05). The incidence of PONV was also less in the SAPB group (p= 0.028). No block-related adverse effects were reported. Conclusion We found that the serratus anterior plane block was more effective than the thoracic paravertebral block for postoperative analgesia after breast cancer surgery.

Reconstrucción de herida compleja de tórax posterior a resección agresiva por cáncer de mama avanzado / Complex chest wound reconstruction following aggressive resection for advanced breast cancer

Los grandes defectos torácicos requieren generalmente procedimientos complejos para su reparación; en la mayoría de los casos es necesaria la combinación de tejidos autólogos y materiales protésicos, por lo que constituye un desafío para el cirujano plástico. En nuestra experiencia se presenta una herida compleja de la pared torácica secundaria a exéresis tumoral. En general se dispone de varias opciones reconstructivas para cubrir los defectos resultantes de las amplias escisiones y poder aportar colgajos vascularizados, amplios y voluminosos. A pesar de no disponer en nuestro caso con los tejidos regionales más comúnmente usados, hemos podido dar cobertura a todo el defecto y se ha garantizado una adecuada estabilidad de la pared torácica. Se tuvo como objetivo mostrar la forma en que se realizó la reconstrucción inmediata con la combinación de colgajo de rotación y material protésico. En este artículo se revisa el hemicolgajo dermograso abdominal, la técnica de elevación y sus ventajas e inconvenientes. Se trata de una técnica de gran seguridad, versátil, con pocas secuelas en la zona donante, de tiempo quirúrgico relativamente corto.

Background: Breast cancer is the most common cancer in the world and represents the main cause of death in women; nevertheless, therapeutic advances have made it possible to increase overall and disease-free survival rates. Looking for a better quality of life, on-coplastic surgery arises, which combines plastic and reconstructive surgery in the surgical management of locally advanced breast cancer, larger or with unfavorable location, seeking to improve the appearance without affecting the oncologic result.Objective: To perform an updated bibliographic review of the oncoplastic approach in the conservative surgical treatment of breast cancer, with the purpose of knowing its oncologic and esthetic results compared to conventional surgical treatments.Material and Methods: The bibliographic search was carried out in the databases PubMed, Elsevier, Hinari, Cochrane and ScienceDirect. Selecting the articles published during the last 10 years, in either English or Spanish, that were related to relevant information in the conser-vative oncoplastic surgical treatment of breast cancer.Results: The search criteria included articles on conservative oncoplastic surgical treatment in women with primary breast cancer, 99 articles met the criteria, excluding those published more than 10 years ago, with unclear or non-reproducible methodology. 35 were eligible, because they were relevant to the subject, published in indexed journals between 2011 and 2021, allowing to determine the clinical, oncological and aesthetic results of conservative oncoplastic surgery and contrast them with conventional techniques. Conclusion: Oncoplastic breast-conserving surgery is oncologically safe and comparable to conventional surgeries (total or partial mastectomy), offering more satisfactory esthetic results and improving the quality of life in patients.

Aesthetic assessment of breast reconstruction in the eyes of plastic surgeons versus nonplastic physicians

SUMMARY OBJECTIVE: The aim of this study was to evaluate the perception of the aesthetic result of breast reconstruction surgery from the perspective of plastic surgeons compared with physicians who are not specialists in plastic surgery. METHODS: Twenty patients who underwent breast reconstruction after mastectomy had their aesthetic results evaluated by 16 plastic surgeons and 16 nonplastic physicians, yielding a total of 620 ratings (320 ratings from plastic surgeons and 320 ratings from other specialists). For all analyses, the level of rejection adopted for the null hypothesis was 5% (p-value <0.05). RESULTS: Significant differences were observed between the two groups. On average, medical professionals who specialized in plastic surgery always obtained higher scores than other physicians. However, no significant differences were found in the assessment of the aesthetic outcome of breast reconstruction according to the sex of the rating medical professional for any of the assessments considered in this study. A strong positive linear correlation between the time since training in the medical specialty of plastic surgery (r=0.750, p=0.001) and the mean aesthetic outcome score was observed in this study. CONCLUSION: Plastic surgeons assessed the aesthetic results of breast reconstruction more positively than nonplastic physicians.

Study on Automatic Plan Method for Radiotherapy after Breast-conserving Surgery Based on TiGRT System / 中国医疗器械杂志

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.

Factors influencing decisions on contralateral symmetrisation procedure among patients with breast cancer

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.

Application of acellular bovine pericardium patch in implant based immediate breast reconstruction / 中华外科杂志

Objective: To examine the clinical effect of acellular bovine pericardium patch in implant based immediate breast reconstruction. Methods: The clinicopathological information of 141 breast cancer patients, who admitted to Department of Breast Reconstruction and Oncoplastic Surgery, Tianjin Medical University Cancer Hospital, underwent immediate mammoplasty with implants combined with acellular bovine pericardium patches were analyzed from June 2016 to October 2019. All patients were female, with the age of (38.8±8.5) years (range: 13 to 60 years). The body mass index was (21.9±2.5) kg/m2 (range: 16.0 to 32.3 kg/m2). There were 39 cases of duct carcinoma in situ, 46 cases of stage Ⅰ, 40 cases of stage Ⅱ and 16 cases of stage Ⅲ. All patients received nipple-areola-sparing mastectomy or skin-sparing mastectomy with sentinel lymph node biopsy or axillary lymph node dissection, and prosthesis implantation with sub-pectoralis combined with breast patch. The correlation of clinicopathological characters and complications was assessed by t test, χ2 test, Fisher's exact probability method and Logistic regression. Pre-and post-operative aesthetic, quality of life scores were recorded. Results: The operation time (M(IQR)) was 3.6(1.5) hours (range: 3.0 to 6.5 hours). The early postoperative complication rate was 22.0% (31/141), prosthesis removal was the main postoperative complication, accounting for 64.5% (20/31) of the total complications, of which 15 cases occurred in the first 30 patients. The follow-up time was 28(8) months (range: 20 to 53 months), The most frequent long-term complications were capsular contracture and implant displacement, with the incidence of 11.2% (14/125) and 10.4% (13/125), respectively. Multivariate analysis showed that prosthesis volume ≥300 ml (OR=8.173, 95%CI: 1.302 to 51.315, P=0.021) and peri-areolar incision (OR=7.809, 95%CI: 2.162 to 28.211, P<0.01) were independent relative factors for the occurrence of short-term postoperative local complications. After 2 years of operation, the score of breast appearance satisfaction was 71.7±15.5, postoperative effect satisfaction was 90.4±9.5, psychological satisfaction was 90.7±17.1, sexual satisfaction was 70.1±25.1. The immediate postoperative satisfaction rate at discharge was 95.4% (134/141), and 17.6% (22/125) of patients had the intention to received revision surgery. Conclusions: Prosthesis volume ≥300 ml and peri-areolar incision were independent realtive factors for short-term local complications after bovine pericardium patch combined with prosthesis implantation in the immediate breast reconstruction. After completing the learning curve, the postoperative complications of the procedure could be decreased.

Surgical management of nipple areola complex in central breast cancer / 中华肿瘤杂志

Objective: To explore the surgical strategy of nipple areola complex (NAC) management in central breast cancer. Methods: A retrospective analysis was conducted on 164 cases of central breast cancer who underwent surgery treatment from December 2017 to December 2020 in the Breast Center of Beijing Tongren Hospital, Capital Medical University. Prior to the surgery, the tumor-nipple distance (TND) and the maximum diameter of the tumor were measured by magnetic resonance imaging (MRI). The presence of nipple invagination, nipple discharge, and nipple ulceration (including nipple Paget's disease) were recorded accordingly. NAC was preserved in patients with TND≥0.5 cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative intraoperative frozen pathological margin. All patients with signs of NAC involvement, TND<0.5 cm or positive NAC basal resection margin confirmed by intraoperative frozen pathology underwent NAC removal. χ(2) test or Fisher exact test was used to analyze the influencing factors. Results: Of the 164 cases of central breast cancer, 73 cases underwent breast-conserving surgery, 43 cases underwent nipple-areola complex sparing mastectomy (NSM), 34 cases underwent total mastectomy, and the remaining 14 cases underwent skin sparing mastectomy (SSM). Among the 58 cases of NAC resection (including 34 cases of total mastectomy, 14 cases of SSM, and 10 cases of breast-conserving surgery), 25 cases were confirmed tumor involving NAC (total mastectomy in 12 cases, SSM in 9 cases, and breast-conserving surgery in 4 cases). The related factors of NAC involvement included TND (P=0.040) and nipple invagination (P=0.031). There were no correlations between tumor size (P=0.519), lymph node metastasis (P=0.847), bloody nipple discharge (P=0.742) and NAC involvement. During the follow-up period of 12 to 48 months, there was 1 case of local recurrence and 3 cases of distant metastasis. Conclusions: For central breast cancer, data suggest that patients with TND≥0.5cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative NAC margin in intraoperative frozen pathology should be treated with NAC preservation surgery, whereas for those with TND<0.5 cm or accompanied by signs of NAC invasion, NAC should be removed. In addition, nipple reconstruction can be selected to further improve the postoperative appearance of patients with central breast cancer.

Características y manejo del cáncer de mama precoz en mujeres añosas asistidas en la Unidad Docente Asistencial de Mastología del Hospital de Clínicas en el período 2011-2018 / Characteristics and management of early breast cancer in elderly women assisted in the Mastology Care Teaching Unit of the Hospital de Clínicas in the period 2011-2018 / Características e manejo do câncer de mama precoce em idosas atendidas na Unidade de Ensino de Mastologia do Hospital de Clínicas no período de 2011-2018

Introducción: Existen pocas pautas para el tratamiento del cáncer de mama (CM) en pacientes añosas, lo que puede conducir al sub o sobre tratamiento. Objetivo: Conocer las características, manejo y la evolución del CM precoz en mujeres añosas. Material y métodos: Estudio observacional, descriptivo, transversal. Se recolectaron datos relacionados con las características clínico-patológicas y la evolución de pacientes de 70 años o más tratadas por CM en el período comprendido entre el 1/1/ 2011 y el 31/12/ 2018, asistidas en el Hospital de Clínicas. Se utilizaron herramientas de estadística descriptiva y para calcular la sobrevida global (SVG) se utilizó el método de Kaplan-Meier. Resultados: se incluyeron 31 pacientes; la edad mediana al diagnóstico fue 76,8 años; las características clínico-patológicas fueron: carcinoma ductal: 71%; GH 1-2: 74,2%; estadio I: 54,8 %; sin metástasis axilares: 80,6 %; HER2-RE/RP+ 80,6%; HER2+ 16,7%, y triple negativas 3,2%. El 29% de las pacientes fueron diagnosticadas mediante tamizaje poblacional y el 74,2% recibieron tratamiento según pautas vigentes, mientras que el 38,7% fueron subtratadas y el 16,1% sobretratadas. La mediana de SVG fue de 98,7 meses. Conclusiones: Una minoría de las pacientes fue diagnosticada mediante tamizaje poblacional, el tipo histológico más frecuente fue el ductal y la prevalencia de los tumores HER2-RE/RP+ fue mayor que en las pacientes más jóvenes. La mayoría de las pacientes recibió tratamiento estandar.

Introduction: There are few guidelines for the treatment of breast cancer (BC) in older patients, which can lead to under- or over-treatment. Objective: To understand the characteristics, management and evolution of early BC in older women. Material and methods: Observational, descriptive, cross-sectional study. Data were collected on the clinical-pathological characteristics and evolution of patients aged 70 years or older, treated for BC in the period from 1/1/ 2011 to 31/12/ 2018, at the Hospital de Clínicas. Descriptive statistical tools were used and the Kaplan-Meier method was applied to calculate the overall survival (OS) rate. Results: 31 patients were included; median age at diagnosis was 76.8 years old; the clinical-pathological characteristics were: ductal carcinoma: 71%; HG 1-2: 74.2%; stage I: 54.8%; no axillary metastases: 80.6%; HER2-ER/PR+ 80.6%; HER2+ 16.7%, and triple negative 3.2%. Of all the patients, 29% were diagnosed through screening and 74.2% were treated according to current guidelines, while 38.7% were under-treated and 16.1% over-treated. The median OS was 98.7 months. Conclusions: A minority of patients were diagnosed by screening, the most frequent histological type was ductal and the prevalence of HER2-RE/RP+ tumors was higher than in younger patients. Most patients received standard treatment.

Introdução: Existem poucas diretrizes para o tratamento do câncer de mama (CM) em pacientes idosos, o que pode levar ao sub ou excesso de tratamento. Objetivo: Conhecer as características, manejo e evolução do MC precoce em mulheres idosas. Material e métodos: estudo observacional, descritivo e transversal. Foram coletados dados relacionados às características clínico-patológicas e à evolução dos pacientes com 70 anos ou mais atendidos por CM no período de 01/01/2011 a 31/12/2018, atendidos no Hospital de Clínicas. Ferramentas de estatística descritiva foram usadas e o método de Kaplan-Meier foi usado para calcular a sobrevida global (SVG). Resultados: 31 pacientes foram incluídos; a mediana de idade ao diagnóstico foi de 76,8 anos; as características clínico-patológicas foram: carcinoma ductal: 71%; GH 1-2: 74,2%; estágio I: 54,8%; sem metástases axilares: 80,6%; HER2-RE / RP + 80,6%; HER2 + 16,7% e triplo negativo 3,2%. 29% dos pacientes foram diagnosticados por triagem populacional e 74,2% receberam tratamento de acordo com as diretrizes atuais, enquanto 38,7% foram subtratados e 16,1% supertratados. O SVG médio foi de 98,7 meses. Conclusões: A minoria dos pacientes foi diagnosticada por rastreamento populacional, o tipo histológico mais frequente foi ductal e a prevalência de tumores HER2-RE / RP + foi maior do que em pacientes mais jovens. A maioria dos pacientes recebeu tratamento padrão.
